Title: Combined spirally grooved radial shaft-sealing ring - is designed to produce very low power loss and suffer min. near, but can be used for almost any high pressure or speed of revolution
Inventor: KAYSER ALBRECHT DIPL ING
IPC: F16J15/00
Filed: 1992-02-28
Abstract: A combined spiral groove-radial shaft-sealing ring has an annular space behind the radial elastomer member used as an annular membrane, and this space is connected by bores in the wall to the high pressure in the shaft clearance. The main body of the prod. has an axial low friction seating to guide a well-fitting axially moving spiral-groove ring which has a spirally grooved area to supply a liquid on its front face, the ring being radially offset at the rear and held so that it cannot turn. The low pressure is connected to the outer annular part of the rear of the spirally grooved ring by gaps. The inner ring is fixed, glued or cured on to the annular membrane. The spirally grooved ring is axially sufficiently long to be tight against the annular membrane and to press it by the grooved part against the smooth radial face of the shaft or rotor. The rear face of the spirally grooved ring takes the high and low pressures in such a way that the resultant axial force equals the pressure exerted (at the nominal speed of revolution) on the front face of the ring by the liquid pressure rising from the low to the high pressure in the gap at the spiral grooves. ADVANTAGE - The lightly loaded radial ring produces very low power losses and suffers little wear. On the other hand it can be used for almost any high pressure and it withstands high speeds of revolution. In the case of reciprocating action the floating spirally grooved ring allows oil to be fed under control to the moving shaft.

Title: Collision detector for vehicle equipped with airbag restraint - has manual switch preventing inflation of airbag, by inhibition of logic circuit which would otherwise respond to signal from accelerometer
Inventor: KAWABATA MUNEHIRO
IPC: B60R21/015
Filed: 1992-10-27
Abstract: The appts. has a manual switch (14) which renders an airbag system inoperative by earthing one input of an OR circuit (15).

Title: Quick-acting lock for cylindrical smooth pipe ends and bores
Inventor: KLEIN HERMANN
IPC: F16L55/11
Filed: 1993-07-21
Abstract: In pressure tests, smooth pipes or bores have hitherto been closed in a laborious manner by welding them shut, by pressing them by means of rubber springs, or by forcing blank covers onto them. In contrast, the novel method is easy and quick as well as exceptionally safe to operate. The novel quick-acting lock enables a reliable anchorage to be found in the bore or pipe interior by means of the expanding bolt (8) and the expanding pieces (9) shown in Fig. 1. The quick-acting lock is removed after releasing the pressure by slackening the nut (16). The quick-acting lock is used in the test and operating area of hollow bodies. <IMAGE>
