Title: Glow plug ignition for Wankel spark ignition engines
Inventor: FRACKE KARL DR
IPC: F02B1/04
Filed: 1982-02-26
Abstract: The invention relates to a glow plug ignition in the Wankel engine, which is controlled by the rotary piston, so that no control elements are necessary for the ignition timing. The purpose of the invention is to ignite a very weak mixture in the Wankel engine, so that not only is the thermal efficiency improved but the emission of pollutants also reduced. This is achieved according to the invention by the glow plugs, since their ignition surfaces are more than fifty times greater than those of the discharge plugs. In the Wankel engine the four cycles are distributed between the four sides of the housing, so that the combustion chamber migrates with the rotary piston. The long, narrow combustion chamber, defined by the seals of the piston, passes the glow plugs at the circumferential speed of the rotary piston, so that the slower combustion speed of the weak mixture is increased. In addition this produces a constant pressure combustion, the lower combustion temperature of which generates correspondingly less nitrogen dioxide. As a result of this simple and reliable ignition system, the Wankel engine is not only the most economical but also the most environmentally friendly vehicle engine.

Patent DE-3344800-A1 (DE)
Title: Special-chain or spur gear mechanism
Inventor: MAJLAND LASLO
IPC: F16H1/32
Filed: 1983-12-10
Abstract: The essence of the invention is the use of the oscillating chain wheel (although a special gear wheel can also be used) which effects the rotation of the chain (or of the gear wheel with internal toothing) since the rotation of the chain wheel (gear wheel) is made impossible by cross-coupling. The solution presented makes it possible to achieve extremely compact and economically priced mechanisms and this is without doubt a considerable advantage. They can be interconnected in a very simple manner and this is also one of their good features. They can also be used as one half of a coupling and the coupling of the mechanism to the machine is thus extremely simple.
Patent DE-3347725-A1 (DE)
Title: Hook for fitting connecting means to elevated stop points
Inventor: JANSEN JUERGEN
IPC: B66C1/36
Filed: 1983-12-31
Abstract: In order safely to reach and leave elevated workplaces, hooks having a safety cable attached to them are used, which are hooked in on an elevated stop point by means of a rod, and are locked after being hooked in. In order to release - and to some extent also to fit - these known hooks, manipulations which are cumbersome to a greater or lesser extent must be carried out during the hooking operation in order to open the unhooking locking device. When using the subject-matter of the invention, which is reproduced by way of example in the figure, such manipulations are obviated, because the unhooking locking device, whose effect is novel, is automatically moved into the protection position after fitting the hook to the stop point, as a result of the force of gravity (acting on the hook) of the handling rod, and is automatically moved into the release position when the rod is lifted, as a result of the effect of the force of gravity of the hook, which force is in the opposite direction to this movement. The subject-matter of the invention can be used particularly advantageously as protection against falling off when climbing up overhead-line pylons. <IMAGE>

Title: Measuring probe and circuit arrangement for the electrical detection of partial discharges
Inventor: LEMKE EBERHARD DIPL ING DR SC
IPC: G01R31/12
Filed: 1984-03-07
Abstract: The invention relates to a measuring probe and circuit arrangement for the electrical detection of partial discharges in electrical equipment. It is the aim of the invention to enable partial discharges in electrical equipment to be detected without having to disconnect system components. The invention is based on the object of ensuring a detection of partial discharge signals of equipment under high voltage without high-voltage coupling capacitors. This object is achieved by the measuring probe consisting of a three-electrode system connected to one another via a compensation network, in which system, on the side facing the device under test, a compensation electrode is arranged between a measuring electrode and a reference electrode constructed in the manner of a housing. Within the reference electrode, two differential amplifiers are integrated, the rise time of which is very small compared with the duration of the TE pulses and is within the nanosecond range. <IMAGE>
Patent DE-3409338-A1 (DE)
Title: Device for the mutual interchange of electrical energy between an AC voltage or three-phase voltage system and a DC voltage intermediate circuit
Inventor: SCHWARZ BERNHARD
IPC: H02M7/757
Filed: 1984-03-14
Abstract: If the DC voltage intermediate circuit of a power-electronic actuating element is supplied from an AC voltage or three-phase voltage system via an uncontrolled rectifier, then it is not possible to reverse the direction of the energy flow, as is often desired. Until now, this reversal has been possible only with a very high level of complexity in terms of power and signal electronics, for example by the use of a reversing converter. The additionally required smoothing means and the relatively long reversal times often preclude technical use. Fig. 2 shows an arrangement which avoids all the said disadvantages. In order to consume electrical energy, the DC voltage intermediate circuit (2) is connected to a three-phase voltage system via uncontrolled half-wave rectifier valves (3) which, in this case, for example form a six-pulse bridge circuit. Connected opposingly in parallel to each uncontrolled half-wave rectifier valve (3) is a half-wave rectifier valve (5), which can be turned on and off and is always in the "on" state when the associated uncontrolled half-wave rectifier valve is conductive while consuming electrical energy, as a result of which current flow is possible in both directions and thus reversal of the energy flow, whose direction does not need to be known. <IMAGE>
