Title: Circuit for supplying an electrical chip with voltage
Inventor: STERLER GEORG
IPC: G01R31/50
Filed: 1987-06-05
Abstract: An electrical chip is provided which represents its malfunction by means of an indicating unit. According to the invention, the indicating unit is not supplied via the main fuse for the chip but via a further circuit, the failure of which, at the same time, leads to the failure of operationally necessary parts in the functional unit with which the chip is associated. The failure of the main fuse then leads to the indicating unit being supplied with power and correspondingly being activated.

Patent DE-3801735-A1 (DE)
Title: Washers which are insulated with respect to structure-borne sound
Inventor: MANTEL JUVAL DR ING
IPC: F16B43/02
Filed: 1988-01-21
Abstract: Screws for fastening apparatuses or installations often constitute sound bridges, the structure-borne sound of the machine being transmitted to the surrounding buildings or building parts or vice-versa. The solution, according to the invention, of the problem consists in the fact that use is made of rigid washers, preferably consisting of metal, which are insulated with respect to structure-borne sound and in which there is located a self-concentrating part which represents the transition from the rubber or structure-borne-sound insulation insert of the washer into a sleeve of this type. Shown in Figure 1 is the device such as can be used, for example, for round or different, projecting screw heads, where a flat, pressure-distributing washer is suitable. Shown beneath the rigid washer (3) are the soft sleeve washers (4) which can be self-concentrating into a bore. In the case of bores with sharp edges, part of the insulating material is loaded to a greater extent, this contributing to structure-borne-sound insulation and not necessarily causing damage to the material. <IMAGE>

Abstract: PCT No. PCT/EP89/01205 Sec. 371 Date Jun. 27, 1991 Sec. 102(e) Date Jun. 27, 1991 PCT Filed Oct. 12, 1989 PCT Pub. No. WO90/07375 PCT Pub. Date Jul. 12, 1990.The invention concerns a process for the continuation granulation of a mixture containing at least one solid material and at least one liquid exhibiting a tendency to gel formation. In order to make it possible to work with a gel-like intermediate phase and yet continue to granulate, it is proposed that a mixture containing liquid raw materials which, by themselves, do not show any tendency to gel be used as the liquid exhibiting a tendency to gel, this mixture being produced in a static mixer, its average dwell time in the mixer being shorter than the gel time. The liquid is subsequently allowed to gel in a stirrer vessel, the dwell time in the stirrer vessel being longer than the gel time. Only then is the highly viscous mass thus obtained granulated together with the solid material.

Title: Surgical gripping forceps
Inventor: STORZ KARL DR MED
IPC: A61B17/22
Filed: 1989-03-25
Abstract: The invention relates to surgical gripping forceps having several forceps legs which are resilient to the outside and which can be extended under an axial spring load from the end of a guide pipe near the patient by actuating an actuation device on the end remote from the patient, and which are centrally contracted by a tension rod. In order to design such gripping forceps in such a way that they are simultaneously suitable for wound gluing, the invention proposes that a channel (2) for insertion of an adhesive substance be arranged in the guide pipe (1) of the gripping forceps. As a result of this, the adhesive substance can be applied through the gripping forceps immediately after closure of the wound by the gripping forceps themselves. <IMAGE>

Title: Process and automatic winding machine for the rewinding of cops to form cross-wound bobbins
Inventor: WEY EDMUND
IPC: B65H54/22

Abstract: Those cops (18) which contain only a deficient quantity of yarn or which have been ejected as being allegedly incapable of being unwound by the automatic winding machine (1) are delivered for rewinding to a specific winding station (7) of the automatic winding machine (1) which is selected and organized for the unwinding of these cops. To make the yarn tension uniform during the rewinding, in the case of each cop (18) to be provided for unwinding for this specific winding station (7), the respective yarn quantity located on the cop tube is determined automatically and is processed to form a yarn-quantity signal. The starting speed of the winding station (7) is put in relation to the yarn quantity and the further winding speed is set, controlled and regulated according to the yarn quantity. <IMAGE>

Title: Centrifugal fan and blower unit for handling grain - has separate drives allowing correct matching of fan and blower characteristics
Inventor: SCHLICK HORST-DIETER
IPC: B24C5/06
Filed: 1989-04-27
Abstract: In the bulk handling of material such as grain, material is drawn from the silo as an air-material mixture and separation takes place in a combination of centrifugal fan and blower. Usually the centrifugal fan and blower are mounted on the same shaft and are driven at the same speed. However the air flow released by the centrifugal fan is ill-matched to the inlet condition at the blower, which ideally should be driven at a higher speed. One of several designs to improve the match between centrifugal fan and blower has an additional motor (41) driving the blower (4'). Co-axial with the blower is the centrifugal fan (2') driven by the motor (1'). ADVANTAGE - Unit is more efficient and can be fitted into a more compact design.
