ABS - American Bureu of Shipping
ABS (American Bureau of Shipping) provides classification, technical, and regulatory services for the marine industry. ABS develops safety rules, guides, standards and other criteria for the design, construction, and survey of marine vessels and structures including all materials, equipment and machinery. ABS certifies companies that provide services, such as measurements, tests, or maintenance, of safety systems and equipment. Additionally, ABS certifies individual materials, components, products and systems used on the vessels through a technical evaluation and survey of manufacturing compliance. ABS is comprised of surveyors, engineers, researchers and regulatory specialists. The rules, guides, and standards are developed by the International Association of Classification and by ABS staff, and they are approved by committees made up of naval architects, marine engineers, shipbuilders, engine builders, steel makers and by other individuals associated with the worldwide maritime industry.
Nacelle - Part of Wind Generator
A nacelle is a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train, and brake assembly.
A notable feature now found on some off-shore wind turbines is a large sturdy helicopter-hoisting platform built on top of the nacelle, capable of supporting service personnel and their tools, winched down to the platform from a helicopter hovering above it. Wind turbine rotors are stopped, feathered and locked before personnel are dropped down to or picked up from the platforms.
Railway Axle Counter
Operation -
An axle counter consists of a sensor, which detects the individual axles of a train by mechanical, electrical or even fibre optic method, and an evaluator which counts the axles passing into and out of a rail section. The evaluator may also convert the analogue signal of the axle sensor into a digital signal. However, in some cases there is a separate unit which performs this task.
The system is set up by having an axle counter sensor installed at each end of a section. As each train axle passes the axle counter sensor at the start of the section, a counter increments. An axle counter sensor comprises two independent sensors (so the device can detect the direction and speed of a train by the order and time in which the sensors are passed). As the train passes a similar axle counter sensor at the end of the section, the system compares count at the end of the section with that recorded at the beginning. If the two counts are the same, the section is presumed to be clear.
This process is carried out by safety-critical centrally located computers, called "evaluators", with the axle counter sensors located at the required sites in the field. The axle counter sensors are either connected to the evaluator via dedicated copper cable or via a telecommunications transmission system. That allows the axle counter sensors to be located a significant distance from the evaluator, and is useful when using centralised interlocking equipment, but less so when signalling equipment is situated beside the line in equipment cabinets.
GBM 50-2 PROFESSIONALMAGNETIC CORE DRILL
Bosch's corded magnetic metal core drill GBM 50-2 is convenient, durable, highly efficient and safe. With the best price-performance ratio in its class, this tool is ideal for tough metal core drilling, twist drilling and threading metal. Its laser technology offers a fast target set-up and power supply cut-off system prevents electric shock. Smart HMI-system enables easy serviceability and controls carbon brush wear, preventing unexpected interruptions. For a long tool lifetime, it features a load indicator that prevents overheating. Magnetic field activation with high magnetic force makes accuracy easy.
Engima Machine
The Enigma machine was a field unit used in World War II by German field agents to encrypt and decrypt messages and communications. Similar to the Feistel function of the 1970s, the Enigma machine was one of the first mechanized methods of encrypting text using an iterative cipher.
Desoldering Pump - Solder Sucker
Desoldering pump or Solder Sucker is used for to remove PCB soldering.
Air Filter Regulator
Function - A filter regulator combines two primary functions. The filter cleans the air that travels from the compressor by straining and trapping any solid particulates, like dust and dirt, and separating liquids from the compressed air. Meanwhile, the regulator controls the speed and precision of the fluid's flow.
