Title: Small press
Inventor: YASUHARU SAKAI
IPC: B23D17/04
Filed: 1982-02-26
Abstract: A small-size pressing or cutting-tool arrangement contains a small-size drive unit and a suitable transmission gear for driving an eccentric cam disc. A lever movable to and fro rests on the cam disc either directly or with devices interposed, the lever being used to drive the pressing or cutting-tool arrangement which is connected respectively via shafts to the lever movable to and fro and to a stationary reaction element. Also described is a control device for a small press, which contains a device preventing the drive motor from being overloaded. Furthermore, there is a timer, which determines when the work cycle of the press takes up more time than a predetermined value, and a position detector which detects the position of a cam disc of the press. The master switch of the drive motor is such that it cuts off the supply of current to the motor when one of the abovementioned circumstances is detected, that is to say, for example, when an excess current is determined, too long a work-cycle time detected or an end position of the cam disc during a work cycle determined.

Title: High-voltage cable with high-polymeric solid insulation
Inventor: PATSCH RAINER DR RER NAT
IPC: H01B7/29
Filed: 1982-03-25
Abstract: The invention relates to a high-voltage cable with high-polymeric solid insulation, in particular polyethylene. Such high-voltage cables are laid in the ground and also installed in pipes through which cooling water flows. These cables which are subjected to a damp environment have been found to undergo local microscopic changes in the insulation, which are referred to as "water treeing" and are attributable to microscopically small particles of salt in the insulation, originating from the damp environment or the cooling water. The object of the invention is to prevent or lessen any formation of water trees occurring under electrical loading in a damp environment in the case of high-voltage cables of the type mentioned at the beginning produced by customary processes. This is achieved by the cable being surrounded during operation by an aqueous solution of which the vapour pressure is below that of pure water.

Title: Transistor ignition system for spark-ignition engines with controllable dwell angle
Inventor: MEHLICH GUENTER
IPC: F02P3/045
Filed: 1983-02-14
Abstract: Customary ignition systems for internal-combustion engines operate over the entire engine rotation range with a constant dwell angle. This has the disadvantage that at a high engine speed the time available for charging the ignition coil becomes too short. In the ignition system presented here, at a specific, presettable speed of the internal-combustion engine, the ignition time is shortened by switching over, in such a way that even at a high engine speed a time period which is sufficient for the full development of the ignition energy is available for the charging of the ignition coil. The switching-over takes place here by means of semiconductor gates. A standard CMOS circuit CD4093 was used in the system. By means of the ignition pulses, a capacitor is charged. The voltage dependent on the charge state of the capacitor is tapped off at a potentiometer and fed to an input of a NAND gate. When the switching threshold is reached, its output is activated. With the aid of a circuit arrangement consisting of 2 NAND gates, a capacitor and a resistor, the ignition pulses are now passed on in shortened form.
