Title: Gauge for checking underground pipes - consists of catch at one end of pipe, compression spring and two axial seals
Inventor: PILAN MANFRED
IPC: G01B5/12
Filed: 1989-08-04
Abstract: The check for pipes, esp. those embedded in the ground, incorporates a gauge (4) whose dia. is less than the nominal ID of the pipe being checked against which it is sealed. The gauge (4) is driven by compressed air from the first end of the pipe through the pipes, so that the volume of air escaping at the second pipe-end is measured. The gauge (4) has a catch (13-15) at the second pipe-end, which consists of another pipe (13) the end (14) of which facing away from the pipe (2) being checked has an annular stop, with compression spring (15), for the gauge and an opening for connecting the volume-gauge. Two axial seals (5,6) are spaced apart from the gauge (4). USE/ADVANTAGE - The pipe-check gauge is quickly and stably put into place when repairing and digging up a damaged pipe.

A second stage of the inaccuracy evaluation and the reciprocal inaccuracy processing are conducted using a further memory unit. USE/ADVANTAGE - For performing inaccuracy evaluation using two or more observation data representing change in object so as to produce corresp. reaction control data.  System eliminates disadvantage of excessive capacity of conventional ones by using separate processor to prestore data in memory.

Title: Application of side folds in lay=flat tubing - reduced friction between blown tubing and folding equipment is obtd. by producing air cushion between tubing and side guides
Inventor: KELCH MANFRED
IPC: B65H45/22

Title: System controls engine knocking - modifying specified characteristics of each working point when knocking is detected
Inventor: GIBTNER SIEGFRIED DIPL ING
IPC: F02P5/152
Filed: 1990-01-19

Title: Multi-plate clutch for motor vehicle - has two stage actuation to ensure complete separation of clutch discs
Inventor: WITTMANN JOHANN
IPC: F16D23/12
Filed: 1990-04-06
Abstract: The motor vehicle is fitted with a multi-disc clutch (1) which held in engagement by a spring. The clutch is disengaged by depressing the clutch pedal (2) which directly actuates a first piston (7) which operates in a cylinder (6). This first piston abuts against a second piston (8) which drives hydraulic fluid into a hydraulic cylinder which disengages the clutch. The initial movement of the clutch is only sufficient to move the clutch discs so they are not longer in metal to metal contact but a residual torque is still transmitted due to the drag of the oil on the faces of the clutch disc. The movement of the first piston opens ports which allow high pressure hydraulic fluid to act on the second piston (8) which is pressed further forward and causes the clutch plates to be completely separated.
