Title: Fibre-reinforced moulding and process for the production thereof
Inventor: FRANK LOTHAR
IPC: B29C70/08
Filed: 1987-03-12
Abstract: Obtaining an optimum effect of the fibre reinforcement and specification of a simple production process. The fibre reinforcement consists of a layer which extends over only a fraction of the cross-section of that region of the moulding which, under flexural loading, is subjected to tensile loading. The layer consists of two fibre bands 13 and 14 which have different structures and are directly adjacent to one another. The fibre band 13 with the looser structure is directly adjacent to the tensile-loaded surface of the moulding. The novel process for producing the moulding consists in the two fibre bands 13 and 14 being laid, loosely and adjacent to one another, into a casting mould such that the looser fibre band faces the tensile-loadable surface of the moulding and then the material forming the moulding being introduced in liquid form into the casting mould under pressure. The moulding is suitable in particular for forming bowls of kitchen sinks, for sanitary systems and the like. <IMAGE>

Title: Washing and disinfecting machine for endoscopes
Inventor: TAKEI TORU
IPC: A61B1/12
Filed: 1987-04-14
Abstract: The conventional washing and disinfecting machines for endoscopes have the disadvantage that the temperature changes during the individual washing, disinfecting and rinsing processes are not monitored. Since the effect of the liquid disinfectant, in particular, depends greatly on its temperature, uniform disinfection is not guaranteed in the conventional machines. Moreover, there is a great danger of excessively hot liquids causing damage and quality losses to the endoscope, its components and the machine. These disadvantages are avoided in that there are provided a device (124) for determining the temperature of the liquid disinfectant and means (122) for controlling this temperature as a function of the temperature determined. The device for determining the temperature is preferably constituted by thermocouples or the like in the washing space (2) of the machine and in the tank (62) for the liquid disinfectant. The means for controlling the temperature comprise, on the one hand, a first heating unit inside the washing space and a second heating unit (152) inside the tank and, on the other hand, a cooling unit (170) on a liquid supply line (44) or a cold water source (176) with the aid of which cold water can be added to the liquids. <IMAGE>

Title: Solenoid-operated fuel injection valve and method for controlling the fuel injection of an internal combustion engine
Inventor: ENGEL RONALD DIPL ING
IPC: F02M51/06
Filed: 1987-07-22
Abstract: Known fuel injection valves are not suitable for small engines, since it has proved very difficult to precisely meter the smallest amounts of fuel and the large amounts of fuel needed for full load operation.   The new fuel injection valve is characterised in that one of the elements determining the OPEN - CLOSED positions of the closing member is arranged so that it can be adjusted during operation and is thereby suitable for a method of controlling an internal combustion engine, in which signals formed as a function of engine operating parameters are sent to the means of adjusting the fuel injection valve. Problem-free use in small engines has thereby become possible.

Patent DE-3729085-A1 (DE)
Title: Safety motor vehicle with a vehicle front part which is mounted so as to be capable of pivoting downwards and lateral mirror devices
Inventor: AMBROS RICHARD
IPC: B60N2/48
Filed: 1987-09-01
Abstract: The invention relates to a safety motor vehicle with a vehicle front part (260) which is mounted, so as to be capable of pivoting downwards, on an interior space (261) of the vehicle, the vehicle front part being held in a stop position by the pretensioning force of the compression spring (265) of a shock absorber spring unit (265, 266). In order to be able to exert the pretensioning force in a variable fashion, in the present patent application pneumatic springs (298) are additionally attached so as to be capable of pivoting between the front part of the vehicle and the interior space of the vehicle so that the compression spring only produces the required minimum pretensioning force and a control range up to a maximum pretensioning force is made possible by means of the pneumatic springs depending on the pressure applied to them. Thus, when braking on ice, it is for example possible for the rear part of the vehicle to be pivoted merely counter to the pretensioning force of the compression spring towards the front part of the vehicle by the shearing force produced during braking when the pneumatic springs have no pressure applied to them, as a result of which the stability of the vehicle is increased and at the same time lateral veering off of the rear part of the vehicle is avoided. As a result of a highly curved windscreen of the safety motor vehicle which deflects the slipstream laterally, it has been necessary to somewhat modify the mode of operation of the mount of the lateral mirror devices. <IMAGE>

Title: Flexible shaft coupling
Inventor: CHIVARI ILIE
IPC: F16D3/80
Filed: 1987-09-08
Abstract: A flexible shaft coupling comprises a first coupling half (10), which forms an outer ring (12), and a second coupling half (28), which projects with axial dogs (32) into this outer ring (12). The coupling halves (10, 12) are connected in torsionally elastic fashion to one another by a star of leaf springs (60 to 78). Some of the leaf springs (60 to 68) are connected at their outer ends to the outer ring (12), and the others (70 to 78) are connected at their outer ends to the dogs (32). A high torsional elasticity is thereby achieved. In addition, the forces between the leaf springs and the coupling half on the output side are reduced. <IMAGE>
