Title: Hydraulic disc brake for bicycles - has relative distance between brake linings defined by position of brake piston relative to block
Inventor: GAYEK JOACHIM DIPL ING
IPC: B62L1/00
Filed: 1992-07-04
Abstract: The brake has a disc, connected to the wheel hub, and a floating caliper block with two or more brake linings. The required distance between the brake linings (18a,b), e.g. 2xs, plus the thickness of the brake disc (21), is determined by the position of the brake piston (8) relative to the block (1). The distance is defined by impact of the piston on the block. The brake block is moved to achieve the same clearances on either side of the brake disc relative to the linings, by an adjusting screw (22). The screw adjusts the brake block relative to a frame-fastened guide cylinder (2). The impact of the piston on the block may be pre-set by the thickness of a stop washer (14). When the brake is not used, the piston is retained on the block by a spring (11). USE/ADVANTAGE - Hydraulic disc brake can be adapted to all types of bicycles, gives improved braking.

Title: Earth carrier for battery electrodes
Inventor: WARLIMONT HANS PROF DR
IPC: H01M4/72
Filed: 1993-02-24
Abstract: The known earth carriers for electrodes of lead-acid batteries usually comprise grids which are made, for example, by metal casting, from expanded metal, as a lead/plastic composite grid or as an expanded composite material grid. Their disadvantage lies in a relatively large weight and/or manufacturing outlay. Using the novel earth carrier, the lead mass is intended to be reduced to the electrically and electrochemically required minimum and thus the weight of batteries in relation to the storage capacity is intended to be minimised. The earth carrier according to the invention is constructed with current-conducting metal webs (1), which form, together with a metal connecting web (2), a comb-shaped electrode body, in which the metal webs (1) represent the teeth. Transversely to the metal webs (1) there are exclusively arranged plastic webs (3). These plastic webs are connected by a frame (4) and fixed to the metal webs (1). The earth carrier can be used with particular advantage for electrodes of those lead-acid batteries for which low weight is important. <IMAGE>

Title: Linear guide - with aerostatic bearing arrangement (NO-CO2-N2), dynamic and static
Inventor: BOENING MANFRED
IPC: F16C29/02
Filed: 1993-02-25
Abstract: The subject matter of the application is shown by Figures 1, 2 and 3. Figure 1, in cross-section, shows in detail the principle of this aerostatic bearing arrangement. Guide slideways (3) of various profile are shown in a bearing block. Bearing supports (2) with bearing shells (1) are pressed free of play against the guide slideways (3) via a load wedge with compensation for play (4) and a spring tension block (8). This is first of all a sliding-bearing construction with the technically known friction values. If media, such as air, gases and liquids, are fed under pressure to the feed bores (5), an air cushion and medium cushion develop between the bearing shell (1) and the guide slideway (3) so that there is no metallic friction when pressure is present. The spring tension block (8) together with the load wedge with compensation for play (4) is in direct relationship with the pressure which is supplied through the feed bores (5). The air cushion and the medium also contribute to the self-cleaning of the guide. If there is no mechanical friction, only a low noise level develops. <IMAGE>

Title: Displacement (position) measuring system
Inventor: GASS ERNST
IPC: B23Q1/72
Filed: 1993-03-05
Abstract: A displacement measuring system for detecting the displacement of a moving machine element comprises a housing extending in the longitudinal direction, a sensor (detecting element) which is arranged in the housing and extends parallel to the longitudinal direction, and a displacement detecting element which can be moved with respect to the housing in the longitudinal direction and acts in a contactless manner on the sensor. In order to improve the displacement measuring system in such a way that the previously mentioned requirements need no longer be placed on the machine element, it is proposed that the displacement detecting element is immovably guided on the housing by a longitudinal guide in all directions at right angles to the longitudinal direction, that the displacement detecting element is connected to the machine element via a connecting rod, that a first articulation (articulated joint) is provided between the connecting rod and the displacement detecting element and a second articulation is provided between the connecting rod and the machine element, and that the articulations have at least respectively one mobility about an axis which is aligned parallel to that of the respective other articulation.

Title: Torsionally elastic cardan shaft coupling for internal combustion engines
Inventor: GEBHARDT HANS
IPC: F16D3/00
Filed: 1993-09-13
Abstract: The invention relates to a torsionally elastic cardan shaft coupling for internal combustion engines. Cardan shaft couplings between an internal combustion engine and a cardan shaft take up a large amount of space since they have to accommodate large tilting moments, which are introduced by the cardan shafts. It is therefore not possible to accommodate the cardan shaft couplings in the flywheel of an already existing internal combustion engine. According to the invention, both a radial bearing (9) and a thrust bearing (10) are provided to take up the tilting moments introduced, the radial bearing (9) being guided, as is the thrust bearing (10), directly in functional surfaces assigned to the flywheel (1). The functional surface of the radial bearing (9) is here designed as an inner circumferential surface (11) which is machined into the inner edge of the flywheel (1). The functional surface of the thrust bearing (10) is designed as an end face (10a) assigned to the flywheel (1). By virtue of the fact that the radial and axial support takes place directly in the flywheel (1) itself, the torsionally elastic cardan shaft coupling can be installed in the flywheel (1) of an already existing internal combustion engine without the need to make major changes to the flywheel (1). <IMAGE>

Within the housing is a slider (19) which, when the ABS system is not working, is held in an end position by a spring (40) to allow the wheel cylinder to be fed directly from the master cylinder. The port to the pump is closed in these circumstances. In the "ABS active" situation, the slider is pulled back against the spring pressure, closing the connection between regulator and master cylinder, and opening up the pump port. ADVANTAGE - Low cost design combining both safety braking functions.t
