Title: Disposable syringe with bifurcated sealing lip - avoiding piston sealing deterioration on storage with thermoplastic polyethylene sealing lip
Inventor: CHOLEWA JOACHIM
IPC: A61M5/315
Filed: 1990-06-05
Abstract: A disposable syringe contains a piston having a sealing lip at its leading end allowing hermetic sliding of the piston relative to the interior of the syringe housing, the novelty being that the sealing lip (19,20) is bifurcated. Pref. the sealing lip is integral with the piston (16) and both the housing (11) and the lipped piston (16,19,20) are made of a thermoplastic, esp. high pressure polyethylene. ADVANTAGE - The bifurcated lip provides improved sealing which does not deteriorate due to housing expansion on long term storage, allows easy piston suction and compression strokes and is easy and inexpensive to mfr.

Filed: 1990-10-12
Abstract: In the hydraulic press, components (37,38) with a variable length are mounted outside the press zone, coupled to the press (17,34) at one end and fixed in position at the other end. A control (13,39) alters the length of the components (37,38) and, at the same time, the vertical position of the press (17,34) at one speed, and the pressure unit (43,50) at a second speed in relation to the press (17,34). The side components (37,38) pref. have a mechanical stepless drop unit (36) which is activated on a given change of hydraulic pressure on the piston rod (38) within the cylinder (37). The press has a fixed cylinder (17) and a moving piston (43) coupled to a press ram (34,63). The press (17,34) has a retainer system (8,62) with a piston (8) which moves in relation to the pressure unit (43) and lies on a retainer (46) which slides in relation to the pressure unit (43). USE/ADVANTAGE - The press is used for stamping, cutting, shaping, pressing workpieces together or extracting water from materials or, in metalworking, to press shapes. The system gives an accelerated movement and also the press movement, without allowing the pressure unit to drop, in all positions, in the event of a parts failure or a loss of hydraulic pressure. The press can also be positioned rapidly for a pressing action.

Patent DE-4036742-A1 (DE)
Inventor: HONUS KLAUS
IPC: B60T8/00
Filed: 1990-11-17
Abstract: A circuit arrangement for a drive slip control system assesses the speed (vER) measured at a driven spare wheel with a correction factor K(t) in order to maintain or improve the control function even when a smaller spare wheel is fitted. This correction factor (K(t)) is found with the drive slip control inoperative by the comparison between axles of the rotation speeds (vna1, vna2, va, vER) of the wheels on one axle and the comparison of the rotation speed differences measured on the driven and undriven axles. On the transition from very slippery road surfaces ( mu lowuniform) to dry ones ( mu highuniform) without the prior calculation of the correction factor, the slip threshold (S) is temporarily raised. When running on different friction factors on the right and left ( mu -split), a raised slip threshold (SER) becomes effective on the spare wheel if it is fitted on the high-friction factor side.
