Title: Diaphragm pump
Inventor: BECKER ERICH
IPC: F04B43/02
Filed: 1983-03-26
Abstract: A diaphragm pump has a formed diaphragm which possesses an elastic diaphragm section and a piston rod connecting part connecting this to a piston rod or the like. At the same time this has at least two front faces arranged at a distance from one another and essentially facing the delivery chamber of the pump and the elastic diaphragm section has a thickened central area with a free diaphragm connection end directed towards the piston rod or the like, which end is connected at least to that front face of the piston rod connecting part remote from the drive. At the same time the outside diameter (d) of that front face (16) of the piston rod connecting part (19) remote from the drive is smaller than the outside diameter D of that front face of the piston rod connecting part (19) closer to the drive and an annular zone (25) of the diaphragm connection end (15) matched to the surface of the front face (24) close to the drive runs past the front face (16) remote from the drive up to the front face (24) close to the drive and is fixed there. This gives an improved, more loadable connection between the diaphragm connection end and the piston rod connecting part (fig. 1). <IMAGE>

Patent DE-3312066-A1 (DE)
Title: Fuel injection system
Inventor: GMELIN KARL
IPC: F02M69/26
Filed: 1983-04-02
Abstract: A fuel injection system is proposed which serves for the fuel supply of an internal combustion engine. The fuel injection system comprises a metering and distributing valve (1) with post-connected control valves (13), which can be influenced by the fuel pressure in a differential pressure control line (21). The differential pressure control line (21) fits by way of a connecting line (22, 25, 19 or 19', 19) on the fuel supply line (3) and on the other hand can be relieved by way of a control throttle (23). In the parts (22, 25) of the connecting line to the control pressure valve (20) a shut-off or pressure control valve (9) is arranged, which closes in the event of an interruption of the fuel delivery so that the fuel pressure in the differential pressure control line (21) can be decreased and the control valves (13) open and the pressure can be equalised on both sides of the valve seats (16). In another embodiment a solenoid valve (9') is arranged in a line (19') to the line (19), which valve also closes in the event of an interruption of the fuel delivery and permits relieving of the fuel pressure in the differential pressure control line (21). In this embodiment the connecting line (25) is omitted. <IMAGE>

Title: Method for digital sound transmission
Inventor: PEXA GUENTHER
IPC: H04B1/64
Filed: 1983-04-12
Abstract: Method for digital sound transmission in which four sampling values (S1 to S4) are in each case combined to form a companding block and are compressed in a uniform manner, according to a compander characteristic depending on the highest absolute sampling value. The definition of the companding range is safeguarded by means of an error recognition coding; the most significant bits of the sampling values are safeguarded by means of an additional parity bit. The arrangement of sound channels within a pulse frame remains the same so that, apart from the frame identification word, no additional synchronisation information needs to be transmitted.

Patent DE-3328149-A1 (DE)
Title: Overload safety means for a differential-pressure transducer
Inventor: WINTER WERNER
IPC: G01L13/02
Filed: 1983-08-04
Abstract: Overload safety means for a differential-pressure transducer, in which pressures are applied to two diaphragms reinforced with discs, these discs being connected via a link, for example a rod, and being in contact with a bending beam, the deflection of which is detected by wire strain gauges and in which the damage to the mechanical parts, in particular the wire strain gauges, through excessive static pressures on one side is prevented by stops which are located between the discs and stop surfaces and which limit the displacement of the movable mechanical parts to the permissible degree. These stop elements are preferably parts of these discs or of a housing and are designed as rings. By the discs being loaded upon assembly by a pressure which is above the minimum permissible positive pressure, the play of these stop elements can be set exactly without having to fear tolerance problems.

Patent DE-3400076-A1 (DE)
Title: Fuel feed system
Inventor: RINGER KARL L DIPL ING
IPC: F02D33/00
Filed: 1984-01-03
Abstract: In motor vehicles the failure of a fuel pump can lead to a breakdown with serious risk of accident, which moreover cannot be rectified either by the driver nor by a mobile breakdown service. The object of the invention is to obtain early signals which permit a clear early diagnosis and repair and, if these signals are ignored and the fuel pump ultimately fails, to nevertheless supply the engine with fuel for a certain time but in any event to signal the failure of the pump so that on the one hand there is no risk of accident and on the other so that the driver is warned to look for a garage. For this purpose an intermediate tank with its own fuel display is built into the fuel line between pump and carburettor so that the fuel flows to the carburettor down a gradient. In the case of injection pumps which work with a pressurised fuel supply, an intermediate tank can be fitted at any suitable point in the manner of the accumulator tank common in hydraulic systems.
