Title: Method for signal generation and signal evaluation by the use of a rubber body
Inventor: STIEFELMEYER GUENTHER
IPC: E05F15/44
Filed: 1984-03-27
Abstract: The invention relates to a method for signal generation and signal evaluation by the use of rubber bodies. The object of the invention is, in contrast to the hitherto known method of utilising a deformation-related pressure rise in a hollow rubber profiled piece closed in an air-tight manner on all sides, to find a way of allowing signal generation and signal evaluation irrespective of the particular cross-sectional shape of a commercially available rubber body, that is to say also with regard to rubber bodies having a solid profile. This object is achieved, according to the invention, in that the change of the electrical properties of the rubber body which occur as a result of a mechanical deformation of the rubber body is detected and is used to trigger a switching operation.

Patent DE-3433106-A1 (DE)
Title: Wiper arm, in particular for wiper systems on motor vehicles
Inventor: EDELE REINHARD
IPC: B60S1/34
Filed: 1984-09-08
Abstract: A joint component with a wiper rod attached to it is swivellably coupled to the attachment component of a wiper arm. A contact pressure spring is hooked into the attachment component and to the wiper rod. In order to obtain a stable folding-away position of the joint component and of the wiper rod even on this side of the dead-centre of the contact pressure spring, a support which is swivellably mounted on the attachment component engages between the wiper rod, which projects into the joint component, and a clamp component. The clamp component has a locking nose over which the support jumps when the joint component and the wiper rod fold away during the outward deflection of the wiper rod. The spring force of the wiper rod keeps the support on one side of the locking nose and thus holds the joint component in the folded-away position. In order to obtain a locking force which ensures a securely maintained folded-away position, the clamp component is attached, as a separate component at a distance from the locking nose and, viewed from the latter, in front of the attachment point between wiper rod and joint component, to the wiper rod. If the support crosses over the locking nose, only the section in front of the attachment point of the joint component on the wiper rod can then deflect outwards.

Title: Aeration of water bodies
IPC: C02F7/00
Filed: 1985-07-12
Abstract: Water bodies should be aerated, their self-cleansing power would drastically increase. For this purpose, funnels are to be anchored into the water bodies in such a way that the water can flow in from the top, by a twisting action can take in air from the top by suction and at the bottom, by a bend of the outlet pipe, can flow out again from the apparatus downstream. Air is to be fed from outside the water body by feed pipes into cavities behind the funnel, is to be able to enter into the twisting water column through pores and the twisting motion is to be forced by means of a thread. On the downstream side of bridge piers, half-round pipes should project into the water with many pores for entry of air into the water, since the waters washing around the piers produce a draught and can thus take in air by suction.
