Patent DE-4336515-A1 (DE)
Title: Power-transmission belt and power-transmission system containing it
Inventor: KIMURA TAISUKE
IPC: F16G5/20
Filed: 1993-10-26
Abstract: A low-noise and robust toothed belt is to be created. The belt (10) has a belt body (12) which has a multiplicity of teeth (22) over the belt length. The teeth (22) are provided at a distance from one another and engage in a belt pulley interacting with the belt. Adjacent teeth (22) are configured (shape, length and pitch) and arranged (distance) relative to one another in such a way that they touch one another when the power-transmission belt (10) is wound around a belt pulley which interacts with it and has a diameter of 60-130 mm. The gap between the teeth (22) is thus at least temporarily eliminated. In one embodiment, the teeth squeeze together in such a way that adjacent teeth bearing against one another and the belt pulley in engagement with them briefly form a solid mass, so that impact noise is minimised. Drive belt for motor vehicles. <IMAGE>

Title: Pressure sealing system for rotating shaft - has conical surfaces pressed together to compress flexible O=rings on facing rings surrounding shaft
Inventor: EHGARTNER HEINZ
IPC: F16J15/34
Filed: 1993-11-14
Abstract: The sealing system is for the shaft (1) of a cellular lock system under pressure. Leakage from the chamber with the rotor (2) is prevented by O-rings (10,11) compressed between rings (5,6) surrounding the shaft and conical surfaces on the casing (3) and a pressure sealing ring (9) fitting onto the shaft. The pressure sealing ring (9) is pushed towards the rotor chamber, compressing the O-rings. A bearing flange (4) is bolted (4a) to the casing (3). The space behind the O-rings is filled with grease (13), introduced through a grease nipple (14) and released through a control channel (15). USE/ADVANTAGE - Seal for rotating shaft which can stand high pressure differential.
Patent DE-4341167-A1 (DE)
Inventor: HIESTAND KARL
IPC: B23Q1/00
Filed: 1993-12-02
Abstract: In an arrangement (1) for the transmission of a pressurized medium from a fixed, outer component (21) into a rotating, inner component (31) which are provided with allocated pressurized-medium passages (26, 27 and 36, 37 resp.), the outer component (21) is fastened to a housing (2) of a machine (M), and the inner component (31) is fastened at a radial distance from the component (21) to a spindle (3). In addition, to compensate for the radial distance, in each case an intermediate piece (41, 42) held in a rotationally locked manner is inserted between the outer component (21) and the inner component (31). The intermediate piece (41, 42) is provided with a passage (45 or 46), is laterally supported on one of the components via in each case radially directed sealing gaps (47, 48 and 49, 50 resp.) and is adjustable relative to the other component (21). This ensures that the two components (21, 31) are not directly supported on one another and do not enclose an axial sealing gap, but nonetheless transmission of pressurized medium is possible. Positional changes of the components (21, 31) are also automatically compensated for and positional inaccuracies cannot have an adverse effect. <IMAGE>

Title: Detecting occupation of vehicle parking space
Inventor: KUEHL BURKHART DR
IPC: G08G1/042
Filed: 1993-12-07
Abstract: A magnetic field sensor, e.g. Hall effect device (1), is used to detect the presence of a vehicle within a parking space.

Title: Metal part detector e.g. for recycling plant
Inventor: SCHOENBERGER LUDWIG
IPC: G01V3/10
Filed: 1993-12-15
Abstract: An alternating magnetic field is generated in a section of the flow being monitored by a transmitter coil supplied by an alternating current generator (G). The phase and amplitude variations of the field are detected by a coil system supplying an evaluation circuit which derives the detection signal. The frequency of the electromagnetic field generated by the a.c. current generator lies below 5 kHz, esp. between 200 Hz and about 1 kHz. The evaluation circuit is designed and tuned to enable a detection signal to be derived for small high density parts.
