Title: Metering unit for plastic compositions
Inventor: KERROM ROGER
IPC: G01F11/04
Filed: 1986-03-05
Abstract: The device for the metered dispensing of plastic compositions has a pressure piece (4) acted on by hydraulic fluid and a piston rod (5) connected thereto. The piston rod (5) can be telescopically inserted into a cylinder (6) and the latter in turn into a further cylinder (9). The pressure piece (4) connected to the piston rod (5) acts on a forcing-out plunger (3) of a cartridge (2) for forcing out the composition. The piston rod (5), the cylinder (6) and the further cylinder (9) are connected to one another via a tension element (14) which delimits the displacement paths of the individual parts with respect to one another. By virtue of the fact that the parts such as piston rod (5), cylinder (6) and further cylinder (9) can be telescopically slid one inside the other, a short construction of the device is achieved. <IMAGE>

Patent DE-3615860-A1 (DE)
Title: Device for pressing strands
Inventor: NIECKAU BERND
IPC: B30B11/22
Filed: 1986-05-10
Abstract: The invention relates to a device for pressing strands, especially thin strands of compounds for plaiting, for example to make Streusel.   The aim of the invention is to bring about a considerable increase in efficiency while keeping energy consumption the same, to reduce the outlay on maintenance, to extend the scope of the device and to facilitate loading. This is achieved by the use of conical rollers, which are each driven through 120 DEG  in a star head by a central drive shaft, the conical rollers being widest in the vicinity of the axis of the drive shaft and their diameters tapering outwards, the lower surface lines of the conical rollers extending perpendicularly to the axis of the drive shaft. <IMAGE>

Title: Divider circuit
Inventor: HABERLAND RUEDIGER
IPC: G06G7/161
Filed: 1986-06-12
Abstract: In the evaluation circuit to form the quotient of two mutually independent electrical signals with pulse width modulated rectangular output voltage, a capacitor is loaded reciprocally with the sum of the electrical signals (e.g. the current sum) up to a comparison voltage, and then reloaded with the difference of the electrical signals up to a second comparison voltage. The stability of the capacitor to be loaded has no effect on the measured value, since the same capacitor is reloaded at every load cycle.

Patent DE-3641745-A1 (DE)
Title: Roofrack
Inventor: BAUMBACH GUENTER DIPL ING
IPC: B60R9/045
Filed: 1986-12-06
Abstract: The invention relates to a device taking the form of a roofrack for motor vehicles, which is used to accommodate loads on the roof of vehicles. Known roofracks in the form of rails are unable, without additional devices, to ensure a fastening transversely to the longitudinal direction of the vehicle and to accommodate a load which is distributed over the entire surface of the roof. The aim of the invention is to integrate additional measures and means for reinforcing the roofrack taking the form of rails, so that separate storage of additional parts either in the garage or in the vehicle itself is unnecessary. The solution is found in roofracks which, in their normal position, are arranged longitudinally parallel to one another in the form of rails, the longitudinal beams or parts thereof being arranged at at least one point of support so as to be rotatable and/or pivotable out of an arrested normal position. The pivot, about which the sections of a longitudinal beam are pivoted, coincides with a base point.

Title: Device for clamping material test pieces in testing machines
Inventor: POHL ANDREAS
IPC: G01N3/04
Filed: 1987-07-16
Abstract: A device for clamping material test pieces in testing machines, with at least one clamping head which is fixed on a cross-yoke, a traverse or the like, is to be designed so that disturbing deformations or cross-forces are avoided on the test piece during clamping. This is achieved by arranging the clamping head (5) on the cross-yoke (3) movably in the cross-direction, so that it can be aligned with the test piece (6). The cross-mobility can be produced by connecting the clamping head (5) to a clamping device which is arranged on the cross-yoke (3) and whose clamping effect can be equalised by supplying pressure means between the clamping surfaces. <IMAGE>
Patent DE-3729770-A1 (DE)
Inventor: STUMPP GERHARD DIPL ING
IPC: F02D41/00
Filed: 1987-09-05
Abstract: Fuel-metering device for a diesel internal combustion engine with an electronic control unit, to which are supplied signals from a lambda-probe which is located in the exhaust pipe. The signals supplied by the lambda-probe serve to place an upward limit on supply of fuel to the internal combustion engine e.g. to direct it in accordance with individual cylinder's requirements. An average is computed on the basis of several probe-produced signals which serves as a threshold, and when the signals from the probe exceed this threshold, the amount of fuel supplied to the cylinders is influenced in such a way that the output signal from the lambda-probe no longer exceeds said threshold. The device serves to monitor conventional flow governors and can also be used as a device for emergency operation.
