Title: Wiper system, in particular for motor vehicles
Inventor: EDELE REINHARD
IPC: B60S1/24
Filed: 1986-12-24
Abstract: The invention relates to a wiper system, in particular for motor vehicles, with two wiper levers which can be moved in an oscillating fashion in opposite directions with respect to each other between an inner and an outer reversal position, and which have wiper blades, the wiping areas of which have a large area of overlap in the inner reversal position. However, there is no fear that the wiper blades may knock against one another since the wiper lever, which in the inner reversal position lies at the bottom, is allocated a means which has the effect that when the wiper levers leave the inner reversal position, the first mentioned wiper lever runs behind the wiper lever, which lies at the top in the inner reversal position, by a certain angular amount, and the wiper lever, which lies at the top in the inner reversal position, is allocated a means which has the effect that when the wiper levers leave the inner reversal position, this wiper lever runs ahead of the wiper lever, which lies at the bottom in this reversal position, by a certain angular amount. <IMAGE>

Patent DE-3713366-A1 (DE)
Title: Method for controlling a heating installation
Inventor: REINER EUGEN
IPC: F24D19/10
Filed: 1987-04-21
Abstract: In a heating installation without mixing device, at a boiler temperature having, for example after domestic-water heating, a relatively high value, e.g. 85@C, the circulation pump is switched on and off cyclically. The switched-on periods are relatively short at first and the switched-off periods relatively long, so that a temperature results in the heating circuit which fluctuates only slightly from a mean value, owing to the storage capacity of pipe system and radiator. The occurrence of crackling noises and overheating of the rooms are thereby avoided.

Title: Remotely switchable intermediate plug socket with feedback
Inventor: LIEBSCHER GERHARD ING GRAD
IPC: H02J13/00
Filed: 1988-02-12
Abstract: Remotely switchable intermediate plug sockets or transmitting devices in heavy-current lines for remote switching of loads have until now suffered from the lack of a signal to confirm the respective switching states. Feedback messages on the respective switching states of the intermediate plug socket to the respective transmitters have been achieved by the intermediate plug socket and the remote switch operating as both a transmitter and as a receiver. Remotely switchable intermediate plug sockets with feedback are predominantly used in domestic installations, especially wherever a load is intended to be switched and monitored from a number of points. One particularly energy-saving application is in the case of separate pumps for hot-water circuits in multiple-occupancy dwellings. The switched-on duration can be limited by combination with timers.

Title: Apparatus for continuously mixing a building material
Inventor: GRUBER HEINZ
IPC: B28C5/08
Filed: 1988-03-23
Abstract: Mixing pumps for building materials are known which are charged from a cylindrical supply container by means of an agitator and comprise essentially a mixing pipe which is inclined with respect to the horizontal plane and inside which a screw conveyor, a mixing tool and an eccentric screw pump are arranged in a coaxial arrangement. It is, however, disadvantageous in this arrangement that mutually separate drives are provided for the agitator tool in the supply container on the one hand and for the functional elements accommodated inside the mixing pipe on the other hand. An apparatus according to the invention is, in contrast, characterised by a funnel-shaped container (2) which is placed on the mixing pipe (1), so that the material contained in the container (2) passes into the mixing pipe (1) only under the influence of gravity. Only one motor (11) is required for the drive of the apparatus according to the invention, which motor is connected successively to a screw conveyor (5), an agitator tool (14) and an eccentric screw pump (10) via links (12, 13, 15). As a result of the said link connections, in contrast to the case of a rigid connection, it is achieved that the eccentric, elliptical circulating motion of the eccentric screw pump (10) is not obstructed so that the latter is driven under kinematically satisfactory conditions. <IMAGE>
