Title: Electrical discharge machine - partial and complete short ccts. are detected and used to avoid damage to workpiece
Inventor: TAKARADA EIICHI
IPC: B23H1/02
Filed: 1973-10-16
Abstract: An electrical discharge machine comprises an oscillator which feeds impulses to an electrode via an amplifier and a resistor in the conventional way. Should either partial or complete short circuits occur between the electrode and a workpiece it is known that the rate of rise of current flow between the electrode and the workpiece is very high. This rate of rise is detected by a toroidal coil positioned around the lead to the electrode and used to energise a Schmitt-trigger via a controlling diode which discriminates between fast and slow rates of rise current by the voltage induced in the coil. The output from the schmitt-trigger is passed via a flip-flop to one entrance of an AND gate positioned between the oscillator and the amplifier to isolate the electrode.

Title: Continuous flow water heater - has safety switch operated hy heater overload or excessive pressure in water channel
IPC: H01H9/20
Filed: 1974-01-26
Abstract: A photoelectric receiver is mounted on the heater body. It responds to visible radiation emitted by the heater in case of overload, and trips a safety switch switching off the heater, as in 2, 364, 975. The safety switchi is, in addition, operated by excessive pressure in the water channel. It can be reset from outside, except when it has been operated by excessive pressure, when the resetting device is blocked. Resetting is only possible after a specialist has removed the cover hood and tested the apparatus for faults. It is especially advantageous to have the input fasteners and input contacts covered by an additional protective housing. When the cover hood is removed the photoelectric receiver operates and opens the safety switch by means of a lifting magnet.

Patent DE-2414916-A1 (DE)
Title: D.C. motor constant current regulation - toroidal magnet has output winding to multivibrator to give small amplitude oscillation around reference current level
Inventor: STEINMANN HELMUT
IPC: H02P7/291
Filed: 1974-03-28
Abstract: The operating current of a d.c. motor with an inductive component is maintained essentially constant by a multivibrator triggered by signals from a toroidal core magnet. The electromagnet has three separate windings; a magnetising field coil that provides the reference level for the system depending on the rheostat, the motor induction coil, and an output coil coupled to a multivibrator and a transistor gate. When the supply relay is closed the motor current will change between a positive and negative value dependent upon the magnetic field characteristic of the coil and trigger impulses will be generated to the multivibrator. The motor current will therefore be in the form of a small amplitude oscillation about a reference mean value, with the waveform consisting of two exponentials. The oscillation amplitude will be dependent upon the hysteresis characteristic of the coil.
Patent DE-2415302-A1 (DE)
Title: Electrical distribution board for power vehicles - consists of circuit board carrying components and socket outlet for cables

IPC: H05K1/18
Filed: 1974-03-27
Abstract: The wiring and connection of a vehicle distribution system is simplified, enabling installation by semiskilled labour, by grouping the control components together on a board. For example fuses, control relays and similar units are mounted directly onto a large printed circuit board. Also on the board, and soldered directly to the appropriate conductors, are socket outlets for the wiring to the various services around the vehicle. The use of polarised plugs inhibits the possibility of wrong connections. The board may be contained in a suitable cubicle or box. A defective board is readily replaceable thus minimising the time a vehicle spends under repair.
Patent DE-2419244-A1 (DE)
Title: Anti-blocking pneumatic brake control valve - with solenoid inlet and venting valves connected to time delay logic for optimum response
Inventor: BABLITZKE ADOLF ING GRAD
IPC: B60T8/50
Filed: 1974-04-22
Abstract: The pneumatic anti-blocking brake control valve is operated by solenoid pressure valves and solenoid venting valves. In order to increase the response of the system the valve movements are kept small, with a result that large air losses can occur. The invention couples the solenoid valves to a logic control system which operates the valves with different time delays for applying and venting the brakes so that a rapid venting, without undue air loss, and a rapid reapplication of the brakes is obtained. The arrangement maintains the proportional control between applied and braking pressure.
