Title: Fastening for doors, bonnets, folding tops or the like of motor vehicles
Inventor: CLAAR KLAUS DIPL-ING
IPC: E05B77/36
Filed: 1986-08-21
Granted: 1988-01-28
Abstract: The invention relates to a fastening for doors, bonnets, folding tops or the like of motor vehicles, with a rotary latch which is stressed by a spring-loaded detent pawl and which, as a result of transmission by a rod mechanism articulated on the rotary latch, can be transferred by means of a manually actuable operating lever out of a precatching position, assumed after the rotary latch located in a release position has run onto an associated locking pin, into a main catching position and which, with the reversal of the direction of movement of the operating lever leading to the closing operation, after the automatic cancellation of the catching position of the detent pawl, can be returned to its release position. According to the invention, the operating lever is connected to the rod mechanism in an articulated manner, in such a way that the rotary latch can be pivoted back into its release position under drive by the operating lever, and that, irrespective of the particular position of the rotary latch assumed in the course of the closing operation, the detent pawl can be transferred into a disengaged end position as a result of a positive coupling to the opening movement of the operating lever in the form of the forward drive preceding the rotary-latch drive.

Title: Setting device for split rivets
Inventor: STOEGER LORENZ
IPC: B21J15/06
Filed: 1987-09-22
Granted: 1988-11-24
Abstract: The setting device contains a feed tube by which a split (body-bound rivet) is fed into a setting position, in which the shank of the rivet protrudes from a forward setting head of the device. Arranged within a supporting sleeve of the device is a striking plunger which, in a first forward stroke, pushes the supporting sleeve forwards to an extent such that it holds the rivet head immobile with its front end face, allowing the shank of the split rivet to be inserted into the workpiece. The set-head can be inserted into the device counter to spring pressure until a triggering position for the striking plunger has been reached, whereupon the said striking plunger drives the expansion pin into the shank in an abrupt second forward stroke. By means of the setting device, it is possible to set split rivets in a simple and rapid manner while, at the same time, ensuring that the rivet head always rests firmly against the workpiece.

Title: Variable frequency generator e.g. for motor control converter - has gate circuit between pulse generating oscillator and frequency divider
IPC: H03K23/66
Filed: 1990-10-05
Granted: 1992-03-26
Abstract: A controlled frequency generator uses an input from a constant frequency oscillator (OSC) received by a gating circuit (TR) coupled to a frequency divider (TL). The output from the divider (E-A) is used, e.g., by a motor controlled. The output is also used by a pulse rate multiplier (PRM) coupled to the input gating stage. - A processor (R) generates both the divider ratio and the multiplier control valves. Pulses generated contain specific values that are required to be suppressed. The control applied to the rate multiplier provides effective suppression.

Title: Vehicle drive  with engine and cone pulley gearbox - has torque sensor forming pretension valve and  supplying additional hydraulic pressurised medium to bias cone pulleys in event of torque shocks.
Inventor: SCHOENNENBECK GERT DR ING
IPC: F16H61/662
Filed: 1992-12-12
Granted: 1994-03-31
Abstract: The pretension valve is formed by a torque sensor mounted on one of the gearbox shafts and through the relative movement of at least two valve parts (50,53) throttles the return flow of the pressurised medium. In the event of torque shocks through torque-dependent relative movement of the valve parts the sensor moves an additional volume of the hydraulic pressurised medium through the opening non-return valves (65,66) into the pressurised medium pipes (18,19) leading to the tensioner (15,16). The pretension valve interacts with suitably spaced inlet and outlet pipes (22,59) for the pressurised medium. The valve adjustment which throttles the return flow of the pressurised medium is produced by the movable valve part (53) directly biasing the side remote from the return flow with the pressurised medium coming from the pressure reducing valve (42). USE/ADVANTAGE - Reduced risk of cone pulley gearbox in vehicle slipping in event of sudden temporary torque shocks.

Granted: 1995-07-20
Abstract: A pipe bending appts. comprises pads (1, 2, 10, 11) arranged in two pairs of pads, at right angles to each other. The facing surfaces (3, 4) of the first pair of pads (1, 2) on the longitudinal line of the pipe (17) are equidistant to each other according to the curvature of the pipe on the first bending plane and parallel to each other on the direction at right angles to it.

At least one pad (11) of the second pair (10, 11) acts as a push unit, with a width corresponding to the outer dia. of the pipe (17). The facing wide sides have a longitudinal stretch appropriate for the run of the facing surfaces (3, 4) of the first pair of pads (1, 2). The line of the narrow sides of the second pair of pads (10, 11) follow the curvature of the pipe (17) in both bending planes with troughs (20, 21) to form a channel. When the second pair of pads (10, 11) are brought together, the push pad (11) passes through the closed pads (1, 2) of the first pair.

Filed: 1994-06-01
Granted: 1995-10-26
Abstract: The treatment of sewage sludge comprises mixing a partly dewatered and digested sludge with a mineral raw material. The novelty of the process is that the partly dewatered sludge with a dry solids content of approximately 15% to 30% is added to a raw material composed essentially of two layer clay minerals whose cationic exchange capacity is high due to a low degree of diagenesis; or to granulated natural stone with a clay mineral content of one or more 2 or 3 layer clay minerals, and a granular or powdered sludge-polishing adsorbent material which substitutes the mineral raw material up to a content of 10 wt.%.
