Patent DE-3129259-A1 (DE)
Title: Wiper system, in particular one-arm wiper system for cars
Inventor: SACCO BRUNO
IPC: B60S1/36
Filed: 1981-07-24
Abstract: Wiper systems, in particular one-armed wiper systems for cars, in which the effective length of the wiper arm and/or the angular position of the wiper blade with respect to the wiper arm can be varied during the swinging movement by means of piston rods of hydraulic working cylinders which form parts of the wiper arm, are used to obtain a particularly favourable wipe pattern and for the guidance of the wiper blade in a manner which is favourable in terms of flow. In order to make wiper systems of this type independent of an external hydraulic pump, the invention proposes that a wiper-arm housing part which is placed rotatably on the spindle fixed to the vehicle encloses at least one pump cylinder which is connected to the working cylinder or cylinders and the pump piston of which, which is subjected on both sides to pressure medium, is pushed non-rotatably but in a manner such that it can be displaced in the axial direction, onto the spindle. The invention furthermore proposes that on the outer circumference of the pump piston a slotted guide be provided with which sliding blocks or the like held on the inner wall of the pump cylinder cooperate such that during the swinging movement of the wiper arm the pump piston can be set in a reciprocating movement in the direction of the spindle.

Patent DE-3214155-A1 (DE)
Inventor: STRAUSS KARL-PETER DIPL ING
IPC: H03J7/18
Filed: 1982-04-17
Abstract: The location coordinates, as well as the transmitting station frequencies, of stations that broadcast the same programs by network arrangements or otherwise, are stored so that when a particular program (network) is selected, all these stations broadcasting the same program as a station being listened to which are not more than a prescribed maximum distance from the station being listened to, may be listed in a table in a working store. While a particular station is being listened to, therefore, continuous checking of the station being listened to with other stations broadcasting the same program for relative reception quality can be carried out automatically while a station is being listened to in a moving vehicle, without taking into account the signals broadcast by stations that are too far away. As soon as some other station broadcasting the same program is found to provide better reception, it is automatically tuned in, and from then on the distance criterion is referred to the location of the new station, a new set of stations for signal comparison is selected and the comparative signal checking process is continued automatically.
Patent DE-3219730-A1 (DE)
Title: Arrangement for controlling a hydraulic servomotor
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: F15B11/08
Filed: 1982-05-26
Abstract: An arrangement (10) for controlling a hydraulic servomotor (13) with an electrohydraulic regulating valve (11) is proposed, with which an oil quantity exceeding the nominal size of the regulating valve (11) can be analogously controlled in an energy-saving manner. The pressure difference of a measuring orifice (28) detecting the oil flow via the regulating valve (11) controls an auxiliary valve (12) which can be activated hydraulically and the spool (44) of which, in addition to a centre position (46) blocking its consumer connections (34, 36), has a rapid-travel position (47), and the inflow connection (38) of which is supplied with pressure medium from a low-pressure circuit (15). The partial outputs required during working feed with maximum working pressure of the first pump (14) and during rapid travel by maximum delivery flow of both pumps (14, 15) lead to low energy consumption, the low-pressure circuit (15) being quickly, smoothly and automatically switched over independently of the electrical input signal at the regulating valve (11). <IMAGE>

Patent DE-3247383-A1 (DE)
Title: Current transformer
Inventor: PLESSL ANDREAS DR ING
IPC: H01F38/30
Filed: 1982-12-22
Abstract: A current transformer for a metal-encapsulated, gas-insulated switching installation has current transformer cores (10) which are arranged in metal encapsulation (2) (which is designed to be essentially rotationally symmetrical) and surround an inner conductor (1) which carries high voltage. An earthed, tubular screen (8) is provided between the current transformer cores (10) and the inner conductor (1). This current transformer is always intended to produce reliable measurements of the operating current, which is passed through the inner conductor (1), of the switching installation, even during switching operations which are linked to the occurrence of travelling waves with steep voltage rises. This is achieved in that the screen (8) and metal encapsulation (2) are electrically conductively connected to one another in such a manner that only a portion, which is required for charging the capacitance formed by the screen (8) and the inner conductor (1), of a current, which flows during the propagation of the travelling wave on the metal encapsulation (2), is supplied to the screen (8), and in such a manner that, furthermore, the inner surface of the metal encapsulation (2) in the region of the current transformer cores (10) is virtually free of material recesses and projections. These measures make it possible for the high-frequency current which is linked to the travelling wave to pass through the current transformer without any disturbances and at the same time reliably prevents overvoltages occurring on the screen (8), with respect to the metal encapsulation (2). <IMAGE>
