Patent DE-3377875-D1 (DE)
Title: Device for the collection of various substances present in a liquid
Inventor: METAIS JACQUES JULES
IPC: E02B15/04
Filed: 1983-05-04
Granted: 1988-10-06
Abstract: Separator comprises a tank, ballasted and stabilised to float one way up and partly immersed with the waterline moving up and down the outer surface with the swell. A rise in the waterline is used to press open a non-return inlet flap valve in the shell of the tank. A fall in the waterline subsequently presses open a non-return outlet flap valve to discharge purified water while pollutants are retained within the tank. In flowing through the tank between inlet and outlet valves, the water can be screened to retain solids. It also follows a flow path via baffles and/or internal non-return valve(s) to gravity-separate liqs., semi-liqs. and residual solids from water directed to the outlet valve. A string of modular, floating separators can be used to form a marine barrage to arrest and mop up an oil slick etc. The separator is used to remove pollutants from the surface or near the surface of the sea. A barrage of the separators will recover major spillages of hydrocarbon fuels, etc.

Title: Dressing
Inventor: WEBSTER DAVID FITZGERALD
IPC: A61F13/00
Filed: 1984-03-29
Granted: 1987-07-30
Abstract: A dressing suitable for application to lesions of the skin comprises a conformable apertured film. The film consists of two layers laminated together, the first layer which is the lesion contacting layer is formed from a material which swells in contact with water. The second layer does not swell or swells less than the first layer when in contact with water. When the first layer is placed in contact with a wet lesion the different swell characteristics causes the apertures to open allowing water to pass through the film from the wet surface to the top of the second layer. On a dry surface the apertures are closed. Preferably the apertures are in the form of slits. A composite dressing in which an absorbent for the fluid passing through the film is in contact with the second layer is also described.

Title: Vehicle wheel
Inventor: HUININK HEINRICH DIPL ING
IPC: B60B21/02
Filed: 1984-09-08
Granted: 1989-07-06
Abstract: A vehicle wheel on which can be mounted a pneumatic tire which essentially includes rubber or rubber-like synthetic material, and has a carcass with load-carrying cords which are anchored in the bead regions of the tire via inextensible core rings. The wheel has a rigid rim with laterally outwardly disposed rim flanges; disposed axially inwardly of these rim flanges on the radially outer side of the rim are seating surfaces for the tire. To minimize disrupting effects on the tire tread, while at the same time improving the emergency operating conditions, a support member is disposed axially inwardly of the seating surfaces on the rim. This support member has a diameter which is greater than the diameter formed by the rim flanges. In the region of a given rim flange, the tire wall extends laterally outwardly from a given core ring in a substantially flat manner, and in particular in an angular range of from 0 DEG  to 20 DEG  relative to the axis of rotation of the tire. The carcass neutral line passes through the same region of a given rim flange in such a way as to avoid a turning point. The core rings are eccentrically disposed in their head regions in such a way that when the tire is mounted, the inner diameter of the tire in these bead regions is less than it is during mounting of the tire.

Abstract: The invention relates to an apparatus for cleaning viscous materials, more particularly melted down scrap synthetic materials in a recycling process. The apparatus of the invention comprises a cleaning screen in the form of a strip which can be moved at right angles to the direction of flow of the material to be cleaned, so that the soiled area of the screen may be replaced by a clean area. In order to prevent the synthetic material from escaping when the cleaning screen is advanced, the volume before the screen is enlarged. This reduces or eliminates the pressure upon the screen so that the strip can easily be displaced, with no escape of the viscous material from the gaps in which the cleaning screen is located.
