Shank buttons have a hollow protrusion on the back through which thread is sewn to attach the button. Button shanks may be made from a separate piece of the same or a different substance as the button itself, and added to the back of the button, or be carved or moulded directly onto the back of the button, in which latter case the button is referred to by collectors as having a 'self-shank'. Snap buttons (also pressure buttons or press studs) are metal (usually brass) round discs pinched through the fabric. http://www.jfbutton.com/button/shank-buttons/

A Backup Battery Unit, or uninterruptible power supply (UPS), is primarily used to provide a backup power source to important desktop computer hardware components. In most cases, those pieces of hardware include the main computer housing and the monitor, but other devices can be plugged into a UPS for backup power, depending on the size of the UPS. In addition to acting as a backup when the power goes out, most battery backup devices also act as power "conditioners" by ensuring that the electricity flowing to your computer and accessories is free from drops or surges. http://www.cell2power.com/backup-battery-unit/

Nowadays, PPR is the most commonly used material for pipes and fittings. PPR is a random copolymer polypropylene. In winter, the flexibility of PPR water pipes will decrease, while the rigidity will increase and flatten. If the pipe is impacted by an external force, the surface of the pipe will crack more seriously. Therefore, PPR Pipe manufacturers suggest that when we use or install PPR Pipe and Fittings in winter, we need to be more careful to prevent pipe collisions and littering. Caring for the pipeline means caring for our own water consumption. http://www.chinapepipe.com/ppr-pipe-and-fittings/ppr-pipe/

Slewing Bearings, or turntable bearings, are ball or roller style bearings composed of two concentric rings either of which may include a gear. This type of bearing enhances load support and power transmission in all directions, and is typically employed to support heavy loads for slow applications and large equipment such as earth excavators and construction cranes. The unique power and versatility of slewing ring bearings has made them increasingly valuable in a wide array of industries, including construction, industrial, robotics, machine tooling, and medical applications. http://www.cnslewingring.com/slewing-bearing/
