Title: Car seat tilt mechanism - has tight rope coiled round drum which is released for seat adjustment
Inventor: KLEIN THOMAS DIPL ING
IPC: B60N2/22
Filed: 1980-08-18
Abstract: This car seat adjustment mechanism is continuous, is very compact and easy to operate. This is achieved by using a rope forming several turns in a groove round a drum. The rope is normally pulled tight by a spring, but is released when a seat adjustment is required, the seat being coupled mechanically to the drum. A rope (8) is coiled in a groove round a drum (5), forming several turns, and is held tight by a coil spring (16) acting via a lever (12). The resultant friction prevents the drum rotating round the shaft (9) which also forms the pivot of the seat tilt movement. The housing (3a) is sufficiently close to prevent the rope from leaving the groove. The lever (6) is released from a rack (14) to release the drum for seat adjustment.

Title: Slide valve for oil in water emulsions
Inventor: BLOCK SIEGMAR ING GRAD
IPC: F16K27/04
Filed: 1981-02-25
Abstract: The invention relates to a slide valve (1) for oil in water emulsions. It has at least one piston slide (2) with a circumferential control edge (3) and a circumferential constriction (4) which, together with the longitudinal bore (5) of the housing, forms a transfer passage (6). The working fluid is fed in and discharged via radial housing ports (7, 8, 9). Sealing rings (10, 11) between the annular spaces (12, 13) and the transfer passage (6) are acted upon over their entire circumference by working fluid. The transfer passage (6) has a large cross-section and therefore permits both large and small volume flows. The chambers (14, 15) for the sealing rings (10, 11) are each connected to the annular space (12, 13) at the lower pressure in the direction of the pressure drop. As a result, the sealing rings (10, 11) are pressed into the sealing-ring chambers (14, 15) when being overridden. Point loads on the sealing rings (10, 11) are avoided and sufficiently large cross-sections of flow for the working fluid are provided. <IMAGE>

Title: Device for automatically monitoring the functioning of chilling furniture
IPC: G08B21/18
Filed: 1981-03-18
Abstract: In a device for automatically monitoring the functioning of chilling furniture, in particular refrigerators and freezing cabinets freezers, their operating temperature, which is produced in an adjustable manner by the electrically operated chilling unit, is kept, within narrow limits, essentially constant, in trouble-free operation by a controller, while in the event of overshooting and undershooting of prescribed upper and lower temperature limit values of a temperature range which includes all admissible operating temperatures, warning signals are transmitted to display a fault. In this case, the two temperature limit values can be variably adjusted by means of a switch in each case, the switch assigned to the limit value for the respectively adjusted lowest temperature interrupting the power supply to the chilling units upon undershooting of this temperature, and re-establishing it in the event of subsequent overshooting of this temperature.
Patent DE-3113180-A1 (DE)
Title: Device for detecting a memory overflow
Inventor: GRANZOW WOLFGANG-DIETER DIPL I
IPC: G11C7/24
Filed: 1981-04-01
Abstract: It may occasionally be so that the data to be stored in a memory or in a group of memory locations exceed the storage capacity of this memory or of this group of memory locations. Such a case may occur, for example, if a computer is in demand for a greater time than expected and/or if it is necessary, for carrying out an operation, to call up a considerable number of internested subroutines whose branch addresses have to be registered. In the event of such an undesired exceeding of the storage capacity, either data are lost or data are falsified, without this necessarily being detected. The invention therefore provides for an overflow register (RU) to be connected to the overflow end of the memories (SP) or groups of memory locations which may be affected. The said overflow register is to be loaded with quite specific data. In each operation (INT.) to address these memories or groups of memory locations, it is checked whether or not the data in the overflow register (RU) concerned still coincide with the data originally recorded. If a deviation is established, a predetermined routine is initiated, for example switching off of the computer (R) concerned. <IMAGE>

Provision is made for this purpose of a mechanism consisting of two lever arms (17 and 20) which extend approximately in the longitudinal direction of the axis (11) of the eyepiece tube and engage with one another via pins (21 and 22). <IMAGE>
Patent DE-3119707-A1 (DE)
Title: Activated-carbon catalyst, especially for decomposing hydrazine
Inventor: BRUNNER ANGELIKA ING GRAD
IPC: C02F1/72
Filed: 1981-05-18
Abstract: The purpose of eliminating hydrazine from aqueous solutions can be served by using activated carbon as a catalyst. This, however, has only a low activity, so that the decomposition of the hydrazine requires considerable time. According to the invention, the activated carbon is doped with copper ions and iron ions in amounts from 1 to 20 parts per thousand. This improves the catalyst activity, so that the noble-metal catalysts used hitherto can be dispensed with. The invention is relevant, in particular, for water treatment in nuclear power stations.
