a throttle lever or regulator, which controls the amount of steam entering the cylinders [3]: 75 : 82 a reversing lever or (US term) Johnson bar, which controls the timing of the admission of steam into the locomotive's cylinders. [3]: 65 This is required for two purposes. One is to reverse the locomotive's direction, e.g. when shunting.
Harris Corporation was an American technology company, defense contractor, and information technology services provider that produced wireless equipment, tactical radios, electronic systems, night vision equipment and both terrestrial and spaceborne antennas for use in the government, defense, emergency service, and commercial sectors.
The Class BB 8700 electric locomotives were rebuilt from the BB 8500 (or BB 88500) as the first subseries for the growth in Maurienne. Indeed, while the CC 6500 participated in this task, the reorganization of traction in Maurienne had led them to other services. Since the BB 8500 had been restricted for some years to 150 km/h (93 mph), as a ...

In many countries or regions they are mandatory to be installed at the gas regulator or gas outlet/ tapping point. Depending on the application they are also often used at the torch side as an additional safety device. Flashback arrestors help prevent: Further gas flow in the case of pressure shocks.
Between the regulator and hose, and ideally between hose and torch on both oxygen and fuel lines, a flashback arrestor and/or non-return valve (check valve) should be installed to prevent flame or oxygen-fuel mixture being pushed back into either cylinder and damaging the equipment or causing a cylinder to explode.
Modern regulated supplies mostly use a transformer, silicon diode bridge rectifier, reservoir capacitor and voltage regulator IC. There are variations on this theme, such as supplies with multiple voltage lines, variable regulators, power control lines, discrete circuits and so on. Switched mode regulator supplies also include an inductor.
A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which generates energy via a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator/dynamo, supplying electric current to an incandescent bulb or light-emitting diode. The flashlight must be pumped ...
