Overall, it was more comparable to the 20 mm Oerlikon, though vastly inferior to the 40mm Bofors weapons used by the US and allies in every respect except rate of fire (and only barely in that respect: the Bofors could put out a sustained 120 rounds per minute because of its constant-fire top-fed ammo clip design, whereas the 25mm's frequent ...
The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.
Fittings allow multiple pipes to be connected to cover longer distances, increase or decrease the size of the pipe or tube, or extend a network by branching, and make possible more complex systems than could be achieved with only individual pipes. Valves are specialized fittings that permit regulating the flow of fluid within a plumbing system.
[2] [3] It envisioned a tool that can cut a mortise in single operation - putting it on par with a biscuit joiner on speed while allowing for a more flexible and potentially stronger floating-tenon joint. The tool implementation by Festool involves a router-like spinning shaft with a special shape cutter bit.
Heater ratings for series-string, AC/DC tubes are given in milliamperes; heater ratings for parallel-string tubes are given in volts. A – 4 V heater for 2-cell lead-acid batteries and for AC mains transformers; B – 180 mA DC series heater; C – 200 mA AC/DC series heater
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
Military specification 6V6 tubes and their equivalents. American military services contracted tubes from many sources through the U.S. War Department. They used a Joint Army-Navy Nomenclature System (AN System. JAN) Most of these tubes bear the JAN marking as well as a VT number (VT = vacuum tube). 3106 - 6V6 tube made in East Germany.
The XM25 Counter Defilade Target Engagement (CDTE) System, [5] also known as the Punisher and Individual Semiautomatic Air Burst System was an airburst grenade launcher with programmable ammunition derived from the XM29 OICW.
