Although there is a fair amount of coverage in the media about the crime and corruption in South Africa, such as the arms deal debacle and crime against tourists, there is an underlying moral vacuum which is seldom mentioned. Being aware of the situation "on the ground" may give the reader a proper perspective of what exactly is happening here. Only property crime is dealt with here, as violent crime is a subject on it's own. What follows is actual happenings and observations during normal day to day life. These are not stories or fabrications or even exaggerations, although it may seem that these items are too far fetched to be real. They are real. 1. A train derailed this week. It was[..]

In the case of plumbing products the buzz phrase is "water efficiency", or how much water a particular faucet, shower, or toilet consumes every time it is used. Water restrictions, drought, availability of potable water, and waste are all increasingly important issues as consumers begin to demand plumbing products that reduce their home's overall operational cost, as well as its environmental footprint on the planet. Water meters or not, wasteful toilets mean a strain on municipal water supplies, which in turn mean additional costly infrastructure upgrades for municipalities, as well as pressure on hydro companies to provide additional water supply through new dams and hydro projects.[..]

Just like most of the things that involve the use of a chemical, either medical things or just those stuffs that we use for our personal hygiene, it is always best that we consult the advice of those people like pool experts or professionals or all those people with expertise when it comes to pool chemicals to sanitize your swimming pools. This is done in order to assure that the effects that will be brought by these chemicals is good and not otherwise. We all do well know that not all chemicals are safe especially when it comes in contact with our skin since it can damage our health. Pool chemicals should not be used carelessly since it can possibly produce even more bad results instead[..]

Digester systems that convert waste material into biogas are becoming more prevalent throughout the world. Rural farmers now have a means to produce good quality fertilizer and biogas from waste materials like manure in a cheap renewable way. The problem is that this biogas produced is roughly 60% methane and 29% Co2 with trace elements of H2S, and is not up to the quality of 99% pure methane natural gas if the owner was planning on selling this gas or using it as fuel gas for machinery. The corrosive nature of H2S alone is enough to destroy the internals of expensive plant. The solution is the implementation of a biogas upgrading or purification system. Biogas upgrading is a series of[..]

Old School Arc Welding is not dead. In fact, it is still king. It this age of high tech and robotic welding processes, you might think that old fashioned arc welding might be obsolete. You would be dead wrong in thinking that. Arc welding (often referred to as stick welding) is still responsible for most of the welding in the construction and maintenance of nuclear plants, paper mills, pipelines, and skyscrapers. Old fashioned stick welding may have advanced a lot back in 1927 but since then, it has hardly changed at all. It's the same welding that grandpa did to fix his tractor back in the day. There are lots of reasons why shielded metal arc welding has stood the test of time...these[..]

It is a basic theory that, when we purchase or sell any product or commodities, we are required to calculate it to identify the quantity. So, weighing machines are happened to be the most important part of every manufactured goods or companies which are selling goods. There are a lot of types of scales accessible that meet up the individual requirements of their different type of requirements. A number of them might have required of bench scales, a few may have a need of a platform scale, a few may call for a crane scale and truck scale, while still others a floor scale. Previously, the scale was just a balance, in which the weights were kept on the one side of the balance and the goods[..]

Natural gas is a fossil fuel composed of a mixture of hydrocarbon gases. The primary components are methane, ethane and propane, however the remaining gases and their percentage of the overall composition can vary greatly. For example, the trace levels of H2S in the mixture sometimes lead to the natural gas being labeled as "sweet" or "sour". Natural gas is often measured in British Thermal Units (BTUs). One BTU is equal to the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit at atmospheric pressure. One cubic foot of natural gas has an average heating capacity of approximately 1000 BTUs. The actual heating capacity varies across the country,[..]

Even those that can provide an acceptable on-screen representation of real paper are plagued by problems such as the clunky buttons of the Kindle, the glare of touchscreen systems (due to dual layers) and the potential loss of pens from those that require them. E-paper was developed to reduce the glare of regular screens, but the display technology did not advance with the development of E-paper and e-Ink. However, touchscreen technology is now developing with coatings that can reduce glare, such as the screen that is offered with the new Be-Book Neo, a Wacom touchscreen that combines well with its 6" e-Ink panel to offer clear reading with minimum screen glare. In fact, it could be[..]

When it comes to electronic scales and industrial scales that you use in your business operations, it is important that these business essentials are properly maintained and kept in tiptop working condition. Most businesses rely heavily on the operation of these modern measuring devices that make the daily business tasks easy and hassle-free.

For instances, business establishments that sell fresh vegetables and fruits will be extensively using the measuring instruments as one will have to determine the weight of each of the fresh merchandise that their customers buy. The electronic or[..]

Digital scales are devices to measure weights. These can weigh anything from light weighted to heavy bodies. The scales work on the principle of load cell technology in which load cells sense the weight of objects under certain conditions. The weight thus obtained is transferred into digital or electronic signals and gets displaced in digital formats. Available in varying models, brands, sizes, and shapes, digital scales come with accessories such as batteries, calibration weights, scale pads, and trays. You are also given easy reference manuals with most scales. The scales vary in prices and quality. Digital scales have several advantages over mechanical scales. They are efficient,[..]

A combination Bulk Bag and Manual Dump Batching System weighs bulk materials that are discharged from bulk bags and/or manually dumped from sacks, boxes and other containers, and empties the batch into mobile storage bins. The sanitary system consists of a bulk bag unloading frame, two hoppers, and two flexible screw conveyors that feed a central gain-in-weight hopper under automated control. A programmable controller with manual start button activates either of the flexible screw conveyors to load the first ingredient into the central weigh hopper at maximum feed rate. Load cells supporting the hopper transmit weight gain information to the controller, which steps-down the feed rate to[..]

There are several key points that need to take into consideration before buying weighing scales, these points are below and will help guide you into buying the correct scale for your application. What is the maximum weight you want to weigh up to? The maximum weight required includes any TARE weights that you may need, for instance if you have a pallet of goods that weighs 600kg and the pallet weighs 20kg then a 600kg scale is not suitable. Sometimes it is a good idea to choose the next capacity range available to future proof. What is the increment/division you require i.e 10g/1g/1mg? Increments are the steps in which a scale goes through its range, for instance a scale that has a[..]

Floor scale is a weight measuring device, which is used to measure heavy objects that cannot be lifted easily. The base of the machine is made of heavy duty structural steel and in the housing there are load cells that actually compute the weight placed on the platform. On the load cells rests a flat platform, which is made of heavy duty and corrosion resistant steel to withstand rugged use and a potentially corrosive environment. The electronic display unit indicates the true weight of the measured object. There are many types of floor scales depending upon the type of application. Health scale : It is small, light and portable version of floor scale and can be easily carried around the[..]

Digital scales are electronic devices used to measure weight. Digital scales come in a variety of sizes and colours and are made from a variety of materials. Digital scales differ from traditional scales because they function based on the principle of load cell technology in which electronic load cells sense the weight of objects under certain conditions . Once the weight is calculated it is transferred to digital or electronic signals and then displayed in a digital format. They are available in different models, brands, sizes, and shapes, and usually come with batteries as well as calibration weights, scale pads, and trays. Digital scales, like every other type of product, vary in[..]

Analog load cells traditionally use either strain gauge or piezo designs, both of which give accurate readings but have some limitations. Capacitive technology now allows analog load cells to give precisely calibrated data from within a firm shell. Capacitive technology works by measuring the change in capacitance when an object is placed on the analog load cell. This method gives readings quickly and can also support heavy weight loads. Miniature units require an external conditioner while normal and large sizes have this technology built in. Analog load cells can be used equally well with digital and traditional indicators and calibration tools. USB outputs allow these devices to work[..]

Scales are used to weigh items received in bulk, to make certain you're obtaining the amount you pay for. As food costs increase, checking the weights of items within the receiving region is considered a very strong control point for a smart operation. If the scales aren't accurate, you're wasting time and money. Of course, scales continue to operate even when they're inaccurate, so maintenance often is neglected to keep them in correct calibration. Dust, dirt, and food scraps can very easily clog the sensitive inner workings of the scale and build up friction, which causes inaccuracy. Scales truly get a workout in most food service operations, so you want a great, sturdy model instead[..]

most common platform scale is probably the bathroom scale. However, weighing platforms in industrial settings are actually very different from that type. Industrial weighing platforms must work in the harshest conditions such as exposure to chemicals and hazardous materials, the repeated weighing of heavy loads, and frequent shocks. This mean that industrial weighing platforms must be built tough with the most rugged and durable of materials. There is no standard, uniform size or capacity for industrial weighing platforms. Many different variations are available with capacities ranging from a gram to several thousand pounds. Features to look for in an industrial weighing platform: * The[..]
