Patent DE-4127697-A1 (DE)
IPC: F17C7/00
Filed: 1991-08-21
Abstract: The process relates to the dispensing of gas from pressure vessels having a filling pressure of over 200 bar. To be able to empty these pressure vessels in a technically simple and economic manner without having to give up existing systems for filling pressures up to a maximum of 200 bar, it is proposed, at a vessel pressure of more than 200 bar, to reduce the gas pressure according to the invention by means of a first pressure reducer (5) down to or below 200 bar and then to reduce it to working pressure by means of a second pressure reducer (8). At a vessel pressure in the course of gas dispensing or at a filling pressure of in each case below 200 bar, the first pressure reducer can be bypassed by means of a bypass line (7). <IMAGE>
Patent DE-4134445-A1 (DE)
Inventor: ZAVISKA DALIBOR
IPC: B60T8/42
Filed: 1991-10-18
Abstract: Proposed is an anti-blocking return-feed hydraulic brake system with a flow-control valve (20) fitted as the inlet valve. The flow-control valve (20) has a metering orifice (35) and a master-cylinder connection (64) and pump connection (63). The cross-sectional areas of these connections vary as a function of the position of a piston (22), which is controlled by the pressure drop across the metering orifice (35). During slip control, the master-cylinder connection (64) is shut off or restricted and the pump connection (63) controlled in accordance with the operation of the flow-control valve. This measure has the advantage that, during a brake-pressure control operation, the master cylinder (1) is disassociated from the hydraulic braking circuit, thus ensuring that the slip-control operation is not felt at the brake pedal.

Title: Monitoring jointing, e.g. press or impact, processes with pulsed drive - measuring distance covered by process tool and comparing with defined tolerance bands
Inventor: WUERTZ GUENTHER
IPC: G07C3/14
Filed: 1991-11-16
Abstract: The method involves measuring the distance covered by the process tool over the defined energy input per impulse or strike and the total distance of the jointing part. The tolerance requirement is determined by setting up tolerance bands during  the jointing process.  The measurement values for an error-free process must lie within the bands. A failure strategy depending on the actual faults is used.
Patent DE-4138189-A1 (DE)
Title: Reel for coiling hot metal wire - has axially movable flange to allow width of coil to increase to relieve internal stresses
Inventor: SCHIRN MARTIN
IPC: B65H75/24
Filed: 1991-11-15
Abstract: As the hot metal wire is wound onto a reel, the subsequent cooling of the wire or strip produces transverse stresses in the material. These stresses can be avoided by winding the wire  onto a reel which consists of a core (3), a fixed flange (1) and an axially movable flange (2). The movable flange is held at a distance (a) from the fixed flange, while the material is wound onto the reel. As the material cools, the forces produced by cooling press the movable flange to a distance (b) from the fixed flange so that the internal stresses in the material are relieved. USE/ADVANTAGE - For coiling hot drawn wires,with controlled compensation of transverse stresses.

Title: Signal display indicating malfunction of bicycle's lamps - has green LED electrically in series with rear lamp and mounted on headlamp casing
IPC: B62J6/00
Filed: 1993-07-23
Abstract: An indicator for malfunction of the lamps on a bicycle uses optical or acoustic means, with a variable intensity of indication (light or sound). The system can also be applied to tricycles, motorcycles and other light vehicles. The electrical wiring can be rigidly attached to the bicycle frame, or inside the tubing. The indicator is simply a LED mounted on the headlamp casing, which shows green if the rear lamp is working normally. It is electrically in series with the rear lamp. The circuit is suitable for dynamo power or rectified power from an alternator. Instead of a single LED, several can be used of different colours or size to indicate other conditions, like lamp active but low power output. ADVANTAGE Increased safety for cyclists at night.

Title: Changeover valve
Inventor: MERZ SIEGFRIED
IPC: F16K11/052
Filed: 1993-10-08
Abstract: A changeover valve (1) has an inlet space (4) and two outlet spaces (5, 6). The aperture cross-sections between the inlet space (4) and the two outlet spaces (5, 6) can be closed alternately. For this purpose, use is made of a rotatably mounted, lever-shaped valve element (10) which, in the region of its ends, carries sealing bodies (15, 16) that can be moved against valve seats (8, 9). An axially displaceable spindle (12) engages on the valve body (10), the point of engagement lying between the fulcrum (13, 14) of the lever and one of the sealing bodies (15, 16). An axial change in the position of the spindle (12) operatively connected to the valve element (10) ensures that one of the valve seats (8, 9) can be closed by means of the associated sealing body (15, 16), while the other valve seat (9, 8) remains open. Any desired intermediate positions are also possible. It is advantageous if the valve body (10) is pressed against one of the valve seats (7, 8) by a spring (17). Such changeover valves (1) are advantageously used in heating systems when it is a matter of diverting the flow of the heat transfer medium from one part of the system to another or distributing it between the said parts. In conjunction with a heat meter, it is also possible to charge heating costs to the parts of the system. <IMAGE>

Filed: 1994-02-05
Abstract: For a combination of two different or similar switching devices (1, 2) or other electrical series insertion devices, the housing (1.1, 2.1) can be subsequently centrically aligned. The devices (1, 2) are both electrically and mechanically interconnected and combined into a compact unit by means of connecting components (3, 5, 6) which can be inserted into recesses (1.5, 2.5) in adjacent housings (1.1, 2.1). To prevent the separation of such a combination into the original individual devices (1, 2) or their rearrangement into another combination which may not meet the regulations, each connector (3, 5, 6) can be permanently inserted into the housing (2.1) of one device (2). At the same time it is engaged reliably in the adjacent housing (1.1) so that, after assembly, it is impossible to separate the devices (1, 2) without destroying the connector (3, 5, 6). A part of the destroyed connector (3, 5, 6) remains captive at least in the housing (2.1) of one device (2). The combination is especially suitable for fitting one or more line protection switches (1) with a residual current protection module (2) to provide an FI/LS switch.
