Patent DE-3824239-A1 (DE)
Inventor: DOBLER KLAUS DR ING
IPC: F02M59/44
Filed: 1988-07-16
Abstract: It is desirable for regulating purposes to detect the variations in pressure inside the working chamber (14) of fuel injection pumps (10) without removing the filler cap (20) and opening the fuel circuit. In order to measure the pressure without opening the fuel circuit, the pressure sensor (24) is pressed against the filler cap (20) and the latter's minimal deformations due to pressure build-up in the pump's working chamber (14) are used to generate a measurement signal proportional to the pressure. This type of pressure measurement is particularly suitable for sensing the pressure in driven aggregates without direct access to the pressure chamber.

Patent DE-3836292-A1 (DE)
Title: Bed for snorers
Inventor: FUCHS SIEGLINDA
IPC: A61G7/00
Filed: 1988-10-25
Abstract: Hitherto it has been attempted to solve the problem of preventing snoring in sleeping individuals by devices which are directly attached to the body and force the latter to assume a lateral position. This makes relaxed sleeping impossible. A superficial mattress support which can be pivoted about a longitudinal axis from the horizontal into an inclined position by a controllable drive, rolls the snoring sleeper automatically into the lateral position without waking him, so that he stops snoring. Since the bed can be pivoted back into the horizontal after a short time, undisturbed and relaxed sleep is guaranteed for the snorer. <IMAGE>

Title: Multi-component catalyst for heating boilers
Inventor: ROEHNER ERNST
IPC: F23J15/02
Filed: 1988-12-01
Abstract: The greatest air polluters are industrial and domestic heaters and in second place motor vehicles. In order to combat this harm, strict regulations on the part of the government are to be expected in the near future. In industrial heaters, regulations made are already in force. Now it is the turn of domestic heaters to emit fewer pollutants into the already heavily polluted air. It will not be possible to avoid installing catalysts even into heating boilers as is the case with motor vehicles. In a large percentage of the domestic heating boilers currently on the market, retrofitting of catalysts will not be possible since these heating boilers as a result of their construction make catalyst installation impossible. The installation of catalysts will be additionally problematic as a result of the multiplicity of heating boiler sizes because a special tool will be necessary for the fabrication of catalysts for each heating boiler type which will require enormous costs. The abovementioned variable catalyst makes it possible to eliminate all the abovementioned difficulties. Moreover, only a small tool with low costs is required and, as a consequence of its special construction, it can bridge the different sizes of boiler types with respect to catalyst size without difficulties. A special catalyst cage receives the small catalysts, as a result of which a large catalyst is formed, ... Original abstract incomplete.

Title: Device for cutting off coil wire ends on connecting elements
Inventor: GOTTSCHALK WALTER
IPC: H01F41/10
Filed: 1988-12-09
Abstract: In the case of a known device for cutting off coil wire ends, two cutting parts can be rotated with respect to one another in a cylindrical housing by means of a guide pin which is guided on the one hand in axially parallel slots in the housing and on the other hand in guide curves of the cutting parts. The device is thus relatively costly to produce. In order to be able to produce a device for cutting off coil wire ends at a cost which is as low as possible, the cutting parts (5, 6) are connected in a resiliently jointed manner at their other end to a single connecting part (4), at a distance from one another, forming a cutting body (3) in the shape of a fork. An operating sleeve (14) which interacts with movement control attachments (12, 13) on the cutting parts (5, 6) at its one end in each case and can be displaced axially on the cutting body (3) is used as a movement control part. The device is primarily suitable for use in automatic winding machines. <IMAGE>

Patent DE-3902714-A1 (DE)
Title: Invisible heating on transparent surfaces and bodies
Inventor: HALLSCHEIDT PETER
IPC: H05B3/86
Filed: 1989-01-31
Abstract: For heating transparent surfaces, thin wires were previously used or the transparent surface was ventilated with hot air. The thin wires impair the view, the ventilation is more expensive than a direct electrical heating. The invention makes it possible to heat transparent surfaces such as window panes and laminated-glass panes in such a manner that the heated system does not impair the view. For this purpose, a material is used which has a similar refractive index as the carrier material, that is to say the transparent surface, through which current flows at the same time and which is heated due to its electrical resistance. The conductive material can be applied to the carrier or between the glass panes (laminated glass).
