Patent DE-3321728-A1 (DE)
Title: Dual brake master cylinder
Inventor: REINARTZ HANS-DIETER
IPC: B60T13/565
Filed: 1983-06-16
Abstract: The twin master cylinder (1), which is especially suitable for hydraulic brake systems of motor vehicles, has two bores (3, 4) running side by side in a housing (2), which bores each together with one piston (29, 30) each form a working chamber (11, 12) connected to wheel brakes of a motor vehicle. The pushrod-piston units (25, 26) are connected to one another by way of a yoke (43). The force (F) produced by a brake pedal acts on the yoke (43). So that hydraulic pressure can be simultaneously built up in both working chambers (11, 12) when the twin master cylinder (1) is actuated, a compensating piston (78) separates the two working chambers (11, 12). So that full braking of a vehicle is nevertheless achieved with approximately the same brake pedal travel in the event of circuit failure, the yoke (43) is rigidly connected to the pushrod-piston unit (27). <IMAGE>

Patent DE-3335964-A1 (DE)
Inventor: BARTZICK GUENTER
IPC: B65B13/06
Filed: 1983-10-04
Abstract: The packaging band in packaging machines, especially when it is formed from plastic, was previously temporarily stored in meandering loops. According to the invention, the band is stored in coils in a spiral relationship to each other, whereby the center of the spiral is shifted and the coils have a free intermediary space between each other. The packaging band can be easily fed at a tangent to the start of the smallest coil without sharp bends and removed at the largest coil by means of shifting the center. The spiral can also be in a standing position. It is advantageous in this instance if the packaging band is fed in and removed in the vicinity of the lowest point. The innermost coil is not limited in its size by any fixed stop means, but rather the infeed of packaging band is cut in by a sensing switch when the radius of the inner coil has reached a certain minimum size. The switch also cuts out the infeed to the storage unit in time during operation, so that the outermost coil does not firmly contact an outer ring.

Patent DE-3441752-A1 (DE)
Title: Brake pressure control valve for a hydraulic vehicle brake system
Inventor: SCHMOELZER ERNST
IPC: B60T11/34
Filed: 1984-11-15
Abstract: In this brake pressure control valve, a first control piston (6) designed as a stepped piston, which has a smaller effective surface in the inlet chamber and a larger effective surface in the outlet chamber, is arranged in a valve housing (1) with an inlet chamber (7) for the uncontrolled pressure and an outlet chamber (8) for the controlled pressure. The control piston (6) is forced into a limit position by a first control spring (11) against the controlled pressure and by its movement controls a valve (14), by means of which the inlet chamber (7) and the outlet chamber (8) can be connected to one another. Parallel to the first control piston (6), a second control piston (21) is provided, which with equal effective surfaces is acted upon by the pressure in the inlet chamber (7) and in the outlet chamber (8) and which is forced into a limit position by a second control spring (23) against the uncontrolled pressure. After the closure of the valve (14), the second control piston (21) is displaced towards the outlet chamber (8) under the compression of the second control spring (23) and, when there is a pressure drop in the inlet chamber (7), due to its return into its starting position immediately permits a corresponding pressure drop in the outlet chamber (8). In this way a low-hysteresis pressure control is obtained. <IMAGE>

Title: Staffette pump system for raising water to a predetermined height in stages and its vertical storage for the purpose of achieving a high drive pressure
Inventor: SUHR FRITZ
IPC: F03B17/00
Filed: 1985-01-23
Abstract: The aim of this invention is to create a large energy potential using the atmospheric pressure and to constantly maintain this by means of a water circuit. This is achieved in that water within the area of equilibrium existing between the atmosphere and a column of water is conveyed upwards in stages by way of a plurality of reservoirs and admitted into a high-level tank, and after this has been filled is drained from this, being led back into the bottom reservoir for drive purposes. This system is not confined to natural water deposits and is operative provided that water has been poured into the bottom reservoir until all reservoirs and the high-level tank are thereby gradually filled up by the pumps.
Patent DE-3502430-A1 (DE)
Title: Lockable gear-lever inhibitor for preventing unauthorised operation of motor vehicles
Inventor: FUEREDER GEORG
IPC: B60R25/00
Filed: 1985-01-25
Abstract: Securing of motor vehicles against unauthorised operation can be effected by locking the gear lever in a manner which is favourable in terms of cost and yet effective. The technical device for this purpose is simple and allows agreeable, fashionable design variants. Even retrofitting vehicles already in operation is possible. Theft of a vehicle equipped with the gear-lever inhibitor is as good as impossible without using a skeleton key or a metal saw, which would cause noise and take time and effort. The number of cases of damage should be considerably reduced by means of this invention. Securing means, such as for example the steering wheel inhibitor, which are currently in common use but are less effective and are more complicated, could also in the future be dispensed with. <IMAGE>
