Title: Master cylinder for hydraulic brake systems
Inventor: SAALBACH KURT
IPC: B60T11/20
Filed: 1988-10-18
Abstract: A tandem master cylinder with two central valves for hydraulic brake systems is demonstrated. An O-ring (23), designed as contact pressure element, is arranged in the pushrod piston-side end of the housing (21) of the tandem master cylinder. The O-ring is arranged between a stop disc (27) and a pressure transmitting body designed as plastic bushing (24). In its compressed state, the O-ring transmits an axial force to the secondary sleeve (25) by way of the plastic bushing (24). The secondary sleeve in turn bears on a stop disc (26). Use of the O-ring (23) as contact pressure element results in a play-free seating of the secondary assembly comprising plastic bushing (24) and secondary sleeve (25). By means of the invention a compact construction, especially a shortened overall length of the tandem master cylinder is achieved by simple, skilful means. The disc spring of the prior art, which was needed for contact pressure of the secondary assembly, can be advantageously omitted. In addition the control compression spring of the central valve of the prior art is made dispensable by simple means, that is by strengthening the central valve compression spring (22). <IMAGE>

Title: Device for disposal of sewage sludge - comprises rotating drum dryer and filter band press used instead of centrifuge to improve throughput of sludge drying system
Inventor: JOBST HORST-DIETER
IPC: C02F11/123
Filed: 1989-06-07
Abstract: A system consists of a sludge conveying device, a flocculant soln. prepn. device, a device for introducing the flocculant soln. into the sludge, and a device for drying the sludge.  It is proposed that the dryer should be a rotating drum filter with a water-tight inlet section and a perforated filtration section. The inlet section occupies about one fifth of the length of the drum, and contains at least one agitator paddle. The sludge from the drum filter is further dried in a filter band press in which it is compressed between two moving permeable membranes. The liq. sepd. from the sludge is recirculated to the sewage treatment plant. USE/ADVANTAGE - Used in the disposal of sewage sludge, in which it is desirable to reduce the vol. of the sludge by drying it. A similar existing system uses a centrifuge to separate the liq. and solid parts of the sludge. The proposed system has the advantage that a considerably greater throughput can be achieved at a comparatively low cost.

Title: Input circuit of a colour monitor
Inventor: TOMSIA ZBIGNIEW
IPC: G09G1/28
Filed: 1989-06-08
Abstract: The invention solves the problem with the construction of an input circuit of a two-standard colour monitor which can operate both in colour and in mono, the operating mode being determined by corresponding polarisation of the field synchronising pulses.

The correction element has a first npn transistor whose emitter is connected to frame potential, whose base is connected to the integrator and whose collector is connected via a diode to a V input of the circuit and via a resistor to the base of a second npn transistor. The emitter of the second transistor is connected to frame potential and the collector to the buffer diodes and via a diode to a stationary contact of a changeover switch of the background and character colour inversion element.
