Flashback arrestors with different size and flow rate, and different connections. A flashback arrestor [1] or flash arrestor is a gas safety device most commonly used in oxy-fuel welding and cutting to stop the flame or reverse flow of gas back up into the equipment or supply line. It protects the user and equipment from damage or explosions.
A flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons. Its primary intent is to reduce the chances ...
A flame arrester during testing A flame arrester made for a 91 cm (36 inch) pipe weighing 10 tons. A flame arrester (also spelled arrestor), deflagration arrester, [1] or flame trap [2] is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame.
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 ...
An arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands. Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on CATOBAR and STOBAR aircraft carriers. Similar systems are also found at land-based airfields for expeditionary or ...
An engineered materials arrestor system, engineered materials arresting system (EMAS), or arrester bed [1] is a bed of engineered materials built at the end of a runway to reduce the severity of the consequences of an aircraft running off the end of a runway. Engineered materials are defined in FAA Advisory Circular No 150/5220-22B as "high ...
A flashlight or electric torch (Commonwealth English), usually shortened to torch, is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb , but these have been displaced by light-emitting diodes (LEDs) since the early 2000s.
A full-power flash from a modern built-in or hot shoe mounted electronic flash has a typical duration of about 1ms, or a little less, so the minimum possible exposure time for even exposure across the sensor with a full-power flash is about 2.4 ms + 1.0 ms = 3.4 ms, corresponding to a shutter speed of about 1 ⁄ 290 s. However some time is ...
