Title: Internal combustion engine in which oil is used for lubrication and cooling, especially where the oil cooling represents the only cooling system of the internal combustion engine
Inventor: LICHTNER EMIL DIPL ING
IPC: F01M5/00
Filed: 1987-05-06
Abstract: The invention relates to an internal combustion engine (1) in which oil is used for cooling and lubrication, especially where the oil cooling represents the only cooling system. In order to achieve a rapid warming of the oil inside the heat exchanger, the bypass line (9), controlled by a thermostat (8), is led through the heat exchanger (12) and releases a proportion of the heat to the oil present therein. At the same time the outer coolant feed line (13) to the heat exchanger remains closed by a coolant thermostat (14) in order to accelerate the warming-up of the heat exchanger contents. The two thermostats (8) and (14) are operatively connected to one another and are both infinitely adjustable as a function of the temperature so that the thermostat (14) releases the coolant supply as soon as the thermostat (8) switches the oil circulation from the bypass line to the heat exchanger (Fig.1). <IMAGE>

Patent DE-3723257-A1 (DE)
Title: Safety harness with swimming aid
Inventor: CAMPION CHRIS
IPC: B63H9/10
Filed: 1987-07-14
Abstract: Known safety harnesses have no swimming aids or insufficient swimming aids, with the result that a person who finds himself/herself in difficulties cannot adopt a stable swimming position in the water. The additional fitting of a life jacket, in the case of surfing with a harness, is too laborious and constricts the freedom of movement to too great an extent. The safety harness has a float element configured as a bib. The bib is fastened to a back flap on the safety-harness central part located on the back. A clearance for the head is left between the back flap and the bib. The safety harness is used for surfing or sailing. <IMAGE>

Patent DE-3804685-A1 (DE)
Inventor: SKACH KUNO DIPL ING
IPC: H01H35/38
Filed: 1988-02-15
Abstract: The pressure switch has a switching piston (3) which can be acted on by a control spring (7) against a switching pressure. To adjust the switching pressure, the control spring is supported via a spring plate (10) against the switch housing (1), which spring plate is arranged such that it can be screwed on a threaded spindle (13). The threaded spindle (13) is supported on the switch housing (1), in an axially unmovable manner, and can be turned at random by means of a hexagonal section (15) projecting into free space. A ram (20), connected to the switching piston (3), has two individual stops (24 and 28) between which there engages the end (42) of a rotating lever (43). On the other hand, the switching ram (45) of a microswitch (46) rests on the rotating lever (43), the rotating lever (43) being spring-loaded in the switching direction of the microswitch (46). In order to adjust the switching hysteresis, the one individual stop (28) is formed by a nut (27) which can be screwed on the ram (20). The nut (27) cannot rotate and is coupled in an axially moving manner to a threaded sleeve (31) which is screwed to the switch housing (1). The screwing lifting movement of the threaded sleeve (31) is limited by stops. The threaded sleeve (31) can be rotated at random by means of a hexagonal section (34) projecting into free space. The two hexagonal sections (15 and 34) are located on opposite sides of the switch housing (1). The arrangement ensures separate adjustment, without sticking, of the switching pressure and of the switching hysteresis. <IMAGE>

Abstract: An integrated optical component contains a waveguide (4) having a birefringent waveguide section (7) between two non-birefringent waveguide sections (17, 18) along the surface of a glass substrate (1). The production of the birefringent waveguide section (7) and the non-birefringent waveguide sections (17, 18) is carried out in a first and second ion exchange process through a first and a second diffusion mask with the aid of a first salt melt for the first ion exchange process and a second salt melt of different composition for the second ion exchange process. <IMAGE>

Title: Method and device for detaching vehicle windows
Inventor: GILCH HEINZ DR
IPC: B60J10/70
Filed: 1988-03-15
Abstract: The invention relates to a method and a device for more easily exchanging windscreens. In comparison to the prior art this invention is characterised in that the sealing compound is cut by a multiplicity of wires rather than by an individual wire or a plastic monofilament. Each of these wires only cuts a small portion of the entire cross-section. This requires less force for the cutting-through. Use can therefore be made also of thinner wires which, in turn, require less force for cutting the sealing compound.

Title: Method for the field current control and field weakening control of an excitation winding of a separately excited D.C. machine and circuit layout for implementing the method
Inventor: LADISCH REIMAR ING GRAD
IPC: H02P7/282
Filed: 1988-03-22
Abstract: The invention relates to a method for the field current control and field weakening control of an excitation winding (12) of a separately excited D.C. machine using an antiparallel connection (2) of two bridge circuits (4, 6) which each have four converter valves (T1-T4, T5-T8), two converter valves (T1/T2, T3/T4, T5/T6, T7/T8) which lie facing one another diagonally in one bridge circuit (4, 6) being, for each direction of the field current (IR, IR'), periodically operated in synchronism, and to a circuit layout for implementing the method. According to the invention, a third converter valve (T4, T1, T8, T5) of the driven bridge circuit (4, 6) can be driven periodically in synchronism with the switched converter valves (T1/T2, T3/T4, T5/T6, T7/T8) lying diagonally opposite. In the event of a network failure, a freewheel path is then formed for the field current (IR, IR'), so that no inductive voltage rise (overshoot) occurs. In addition, the field of the excitation winding (12) can be reversed by means of a generated negative field voltage, which brakes the D.C. machine. <IMAGE>

Title: Electrostatic filtration by agglomerating charged contaminant particle - with opposite polarity carriers for later removal from entraining fluid stream
Inventor: KOENIG NIKOLAUS DIPL ING
IPC: B03C3/019
Filed: 1989-07-18
Abstract: While flowing in a liq. or gaseous fluid stream (18), entrained contaminant particles (13) charged at the same polarity are encountered e.g. in cross-flow, by carrier granules or particles (17) of opposite polarity and pref.  of generally equal size in the micron range. The contaminant particles deposit on the carrier particles, mutually cancelling their charges and forming agglomerates which can be  subsequently sepd., eg. by centrifuging, ultrasonics or chemical reaction. The carrier particles may be catalytic and suitable for re-use when sepd. with suitable materials, spen. may be followed by destructive combustion. Both sets of particles may be charged by the same field. Alternatively the carrier particles are charged by electrodes (25, 27) while entering the stream at a downstream location from the initial charging point for contaminant particles (13). ADVANTAGE - Efficient particle sepn. is achieved by a compactly constructed filter.
