Patent DE-4142725-A1 (DE)
Inventor: SCHLEI GUENTER DIPL ING
IPC: F16F9/04
Filed: 1991-12-21
Abstract: For the sealed mounting of a piece of hose made of elastomeric material, especially of hose U-bellows for air springs, on a connecting member, an open end of the piece of hose is pushed onto the connecting member. A metallic clamping ring is positioned such that it surrounds the piece of hose in its pushed-on end region. The diameter of the clamping ring is reduced by radially pressing it together and, in consequence, the piece of hose is firmly clamped on the connecting member in a sealed manner. In order to increase the quality of the clamping in of the end section of a piece of hose, the axial force produced on the connecting member while the piece of hose is being clamped in radially is detected while the clamping ring is being pressed together radially. <IMAGE>

IPC: H04N5/3728
Filed: 1992-10-27
Abstract: In the position-resolving area/sensor video camera, a semiconducting CCD circuit  is uniformly filled with electrons in phase 1. The electrons can then become differently distributed under the influence of the electric fields to be detected during phase 2. This distribution is maintained during phase 3 and is measured. A pyroelectric film on the surface of the CCD circuit causes an electric field distribution corresp. to the local distribution of heat or heat generating radiation which can be measured by the sensor. The results are displayed using holograms, IR imaging, or ultrasound imaging. USE - For determining positional distribution of  electric field.

IPC: D21F1/02
Filed: 1992-11-26
Abstract: At the stock inlet, for a papermaking machine, at least one of the two walls between the first and final chambers has a sliding movement. This alters the contour of the longitudinal section of the suspension flow gap between the walls to give varied and different accelerations and delaying profiles, and eddies. Pref. at least two walls, between the first and final chambers of the stock inlet, have shaped contours so that the max. and min. surface lines between the facing surfaces form a deviating angle of 0-180 deg..

Title: Manual rake for grass and foliage for tending lawns and meadows
Inventor: MARK JOSEF
IPC: A01D7/06
Filed: 1993-01-19
Abstract: The manual rake has a shaft (3) and a crossbar (1) connected to the shaft, a multiplicity of flexurally elastic tines (2) arranged in a row being fastened on the crossbar.

Title: Electrical switch, in particular for an electric toothbrush
Inventor: HERZOG KARL
IPC: H01H21/10
Filed: 1993-06-14
Abstract: An electrical switch 1 is described which has a load-bearing part 2, a frame 4 and a leaf spring 3 arranged in between. The leaf spring 3 consists of two parallel outer webs 5, 6 and two transverse webs 7, 8 which connect them. Those surfaces of the load-bearing part 2 and of the frame 4 which face the outer webs 5, 6 are designed to be concave or convex respectively, corresponding to one another. In consequence, the outer webs 5, 6 are shortened. A centre web 9 of the leaf spring 3, which centre web 9 is arranged parallel to the outer webs 5, 6 and is located between two supporting parts 20, 21, is bent into an S-shape as a result of this shortening. The centre web 9 can snap over into two different positions as a result of forces acting on the two "peaks" of this S-shape. Contact arms 10, 11 which are integrally formed on the centre web 9 project in different directions in these two positions and can thus be used for switching an electrical load on and off. <IMAGE>

Abstract: The oceans and seas serve mankind as a transport route, as an indispensable source of raw materials and food, and not least for rest and relaxation. Despite increased safety measures, there is always the potential risk of water pollution over a wide area from the transport of crude oil or refined oil products (collision, shipwreck, etc.), oil wells at sea and the like. In known floating apparatus (cleaning units) for removing oil and/or oil-like contaminants drifting on the water surface, various constructions with complicated or less complicated mechanisms are used. This novel cleaning unit is to enable oil and/or oil-like contaminants to be picked up with a small proportion of water. In addition, it is to be capable of action in a heavy swell and is to guarantee the continuity of the disposal process. In order to guarantee reliable pick-up of the contaminants with a small proportion of water and continuity of the disposal process even in a heavy swell, two rotating drums (1) hanging on a hoist (2) and half-immersed in the water are provided. The drums (1) are covered with oleophile materials. A second hoist (2) is provided via a hoist device (5) so that alternate raising and lowering of the two coupled hoists (2) permits continuous disposal. The transfer from the drums (1) into the storage tanks (7) ... Original abstract incomplete. <IMAGE>
