Patent DE-2405671-A1 (DE)
Title: DC line overvoltage limiter cct. - has non-lieear series resistor in each long or shunt branch reacting to temp. variations
Inventor: POPP ERWIN DIPL ING
IPC: H02H9/04
Filed: 1974-02-06
Abstract: The overvoltage limiter circuit consists of a voltage arrester(s) coupled, across the load and a positive temperature coefficient resistor coupled between the D.C. supply and the load. When the voltage arrester breaks down, heat is developed in it. The resistor responds to the temperature variations, as it lies in thermal contact with the arrester, so that the resistor resistive value increases to a level that reduces the overvoltage to below the arrester breakdown voltage. After the positive temperature coefficient resistor has cooled down, the load is again supplied with full power. This configuration allows voltage arresters of low breakdown voltages to be used.
Patent DE-2409716-A1 (DE)
Title: Implosion chamber evacuation process - uses high-pressure chamber sealed from atmosphere containing implosion chamber at atmosphere pressure
Inventor: KUDIABOR KODJO DIPL ING
IPC: B65B31/02
Filed: 1974-03-01
Abstract: The process is for evacuating bags of plastic or other flexible material containing foodstuffs such as meat, the walls being imploded onto the contents by subjecting them to atmospheric pressure on the inside and a higher static pressure on the outside. To build up the pressure difference an evacuation system is used, comprising a high-pressure chamber sealed off from atmosphere. Inside this is an implosion chamber connected to atmosphere so that its pressure is the same as the latter. The implosion chamber can be in the form of a bag of sheet material to be evacuated, preferably of plastic, sealed off from the high-pressure chamber and accommodating the product to be packed.
Patent DE-2411421-A1 (DE)
Title: Small bore firearm - has rifled barrel with deep drawn rifling for reducing bullet kinetic energy
Inventor: WITHUM WERNER
IPC: F41A21/18
Filed: 1974-03-09
Abstract: This special barrel is used so that standard ammunition can be used without recourse to an exceptionally short barrel or special ammunition with a small amount of propellant. The speed and the kinetic energy of the bullet is reduced by especially deeply drawn rifling within the barrel and these grooves and lands formed are extended right to the cartridge chamber. The barrel is provided with a maximum of six grooves and lands in the rifling. In addition to the rifling the barrel bore is made undersize in order to provide additional braking effect. The cartridge is held in the cartridge chamber and the rifling lands and a groove are machined into the undersized barrel bore. The rifling is continued right up to the bullet of the cartridge in the cartridge chamber. The cartridge chamber bore and the barrel bore are connected to a truncated conical tapered bore section. This barrel bore rifling ensures that the propellant burns normally yet does not impart excessive pressure on the bullet and the precision of shooting is not affected adversely.

Title: Pressure controlled flow regulator for water cooling systems - diaphragm in pipe wall actuates limit switches controlling throttle valve
Inventor: LUIG ELMAR
IPC: G01P13/00
Filed: 1974-08-12
Abstract: A flow regulating device reacts to pressure in a pipe line to operate limit switches to open and close a circuit coupled to a throttling valve in the line. Flow takes place from input to output over a control valve. A diaphragm located in the wall of the pipe reacts to pressure to move a lever pivotted at one end. As the pressure increases the actuator pin of a contact set is stripped. As the lever moves further an electrical circuit coupled to the control valve is closed. At an upper pressure, a second limit switch is stripped and the circuit opens. The pressure at which the limit switches are operated may be adjusted by varying the position of one of the limit switches over a given range.

Title: Electromechanical filter terminal circuit tuning method - adjusts circuit frequency to coincide with nominal frequency within filter pass band
Inventor: ALBSMEIER HANS ING GRAD
IPC: H03H7/01
Filed: 1974-08-27
Abstract: Each terminal circuit is tuned to a frequency (f3) outside the pass band by a connection of an additional capacitance of known value; an auxiliary frequency (f2) is derived from the values of the above additional capacitance, and a fixed terminal circuit reactance (C1), so that a resonant frequency coinciding with the nominal frequency (f1) is produced after disconnection of the above additional capacitance; then the circuit is tuned to the frequency (f2) and the first additional capacitance is removed. There are two lines connected at intervals by capacitances (C1, C23, C34, C5), and on one line between each of these capacitances there are capacitances and inductances (C2, L2) and (C3, L3) in series. The filter acts as an electromechanical equivalent of this circuit.
