Patent DE-3308575-A1 (DE)
Title: Control valve
Inventor: BRUNNER RUDOLF
IPC: F16K47/02
Filed: 1983-03-10
Abstract: The invention relates to a hydraulic control valve with a spool for controlling the working flow, which spool can be displaced in a housing bore between a neutral position with unpressurised flow and at least one control position, a pressure connection to the housing bore, a through-channel formed in the spool and a drain connection being provided for unpressurised flow. In the known control valves, the pressure connection, the through-channel and the drain connection are dimensioned in such a way that two restrictions with approximately the same restricting effect are obtained for the hydraulic fluid flowing through, with the result that the pressure in the hydraulic fluid is reduced in two approximately equal stages. This results in a troublesome loud noise if the valve is switched out of the neutral position into a working position or vice versa. According to the invention, this noise is reduced by the fact that the pressure connection and the inlet cross-section of the through-channel, on the one hand, and the outlet cross-section of the through-channel and the drain connection, on the other hand, are dimensioned in such a way that the cross-section of passage of the through-channel to the drain connection is larger in every piston position between a fully closed position and a complete overlap between the pressure connection and the through-channel than the cross-section of passage of the pressure connection to the through-channel.

Title: Circuit arrangement for preventing the emission of noise signals
Inventor: NAGLER WERNER DIPL ING
IPC: H04Q11/04
Filed: 1983-03-28
Abstract: The digital useful information to be transmitted from a peripheral module (LTU0 to LTU7) via time division multiplex lines (SIHI) to a central device controls a monostable trigger circuit (M) to whose reset input (R) it is fed, a release signal being supplied to the trigger input of said circuit which release signal primarily effects the connection of the peripheral module to the time division multiplex line using the correct time channel. If errors occur in the continuous release signals, no noise signals can thus be transmitted onto the time division multiplex line once the operating delay of the monostable trigger circuit has elapsed. <IMAGE>

Patent DE-3336002-A1 (DE)
Inventor: KOBER HANS-RUDOLF DIPL ING
IPC: F16C32/06
Filed: 1983-10-04
Abstract: The disclosed guide device utilizes no rigidly mounted external guide elements. However, a guide element freely slidable on an air cushion on a flat base can be lowered from the interior of a slide element (by removal of the air cushion) onto the base. Once the guide element has been lowered, it is fixed by subpressure onto the base and takes over the function of a rigidly mounted guide. The guide element, which was previously freely slidable on the base, is now exactly positionable along the guide of the guided element. If the displacement path is to be increased, then the slide piece element is fixed by subpressure on the base, the guide element is again acted upon with compressed air and driven within the slide piece in a displacement direction and at the end of the interior space is again fixed to the base. Now the slide piece is again released and can on its air cushion be further positioned exactly in the displacement direction. This stepwise movement is limited only by the size of the base.
