Title: Size checker for articles on conveyor - has laser beam and photo detector giving signal to microprocessor
IPC: G01B11/04
Filed: 1975-07-07
Abstract: Optical equipment to check the dimensions of moving objects, and compare the dimensions within given tolerances, is suited to measurement during mass production using a conveyor belt (2) for carrying the objects (I). It produces a beam of parallel light rays (4a, 4b.., 4n), all in one plane perpendicular to the direction of the moving objects (1). A laser (5) generates a beam of light which is divided to give the rays. Optical detectors (7a, 7b,..., 7n) corresponding to the light rays (4a, 4b,..4n) produce an electric current which varies with the intensity of the corresponding light ray. The belt (2) drives a disc (9) with slots which cut a separate light ray (10). Another optical detector (11) measures the belt (2) movement. The signals produced by the optical detectors are fed to a microprocessor. The microprocessor is used to establish conformance with the required dimensions.

Title: Weft thread feeder with constant tension - with hollow revolving shaft for depositing thread turns on drum
IPC: D03D47/36
Filed: 1975-09-26
Abstract: Device for storing on a drum a certain reserve of weft thread which is to be worked with constant tension comprises a hollow revolving shaft with guide eyes, for depositing several thread turns on the drum. Pref. the storage drum is stationary although supported by a rotating assembly, due to an anti-gyrating mass situated in its lower region, and due to its shaft being mounted in two roller bearings. The thread is wound onto the stationary drum, hence without change in torsion. It is deposited at the rear of the drum, and taken off at the front, thus allowing easy rethreading and avoiding overlapping of adjacent turns. Regulation of the quantity of thread stored is obtained by displacement of a reflective opto-electronic assembly onto the chrome-plated surface of the drum.

Title: High speed signal analysing device - uses signal to modulate electron or light beam deflected across charge coupled device
Inventor: LEJEUNE GABRIEL
IPC: G01R13/34
Filed: 1975-11-12
Abstract: A high speed signal analysing device is for the analysis of short duration non repetitive signals arising the nuclear physics, ionization or ballistics etc., it generates a beam of radiation. The beam is modulated by the high speed signal and is simultaneously scanned across a linear charge coupled device (8). In one embodiment an electron beam is generated from a cathode (1) and modulated with the high speed signal applied on line (3) ot a modulating grid (2). An element (4) focusses the beam prior to passage through a beam scanning deflector (6) which scans the beam over charge coupled device (8) under the control of unit (7). The beam may be a laser. Signal to noise ratio may be reduced by simultaneous scanning of three charge coupled devices masked to varying degrees.

Title: Tubular welding or brazing wire contg. flux - having tube made from metal strip with overlapping longitudinal edges
IPC: B23K35/02
Filed: 1976-04-28
Abstract: Welding or brazing wire contains a pickling flux in the form of powder or paste which melts and flows along the wire during welding. The wire consists of a tube formed by bending metal strip where the two longitudinal edges of the strip overlap; and the tube is filled with the flux. The overlap of the strip edges is pref. 30-90 degrees and the resulting tube may also be bent in a circle to form a brazing ring. The tube is pref. made from flat strip bent in four successive operations to make the tube; during forming, two dosing pistols are pref. employed to feed the flux at a controlled rate into the tube. A constant ratio metal flux is obtd. so the wire can be used e.g. on automatic brazing machines.

Patent FR-2333985-A1 (FR)
IPC: B60P1/16
Filed: 1976-11-30
Abstract: The valve consists essentially of a shut-off valve (35) arranged in a housing (31) and serving the purpose of controlling the direct return of a hydraulic fluid pumped to an actuating cylinder by a pump and of a compressed-air cell (32) divided into two chambers (40, 41) by a diaphragm (39). Via a valve pin (38), the movement of the diaphragm (39) is transmitted counter to the force of a spring (63) to a valve element (36) and, as a result, the latter can be raised from its seat (37). The flow of hydraulic fluid to and from the actuating cylinder can be controlled via a lowering valve (54) with two valve elements (56, 57) which is connected mechanically to the shut-off valve (35) and acts as a non-return valve. This control valve makes it possible to tip the tipping body of a tipper vehicle, halt it in any position and automatically lower it rapidly or slowly depending on its loading and to do this in a remote-controlled manner.

Title: Extruded composite hollow elastic profile for car body seals - distended between extrusion and curing to minimise skin thickness
IPC: B29C48/12
Filed: 1976-12-23
Abstract: A flexible strip seal profile having a smooth skin around a hollow foam core is made by coextrusion of the skin and foam materials under conditions which extrude a profile of reduced cross-section with a thick skin. Further expansion of the foam is allowed to dilate the cross-section and draw down the skin to its final thickness, before the profile passes through a vulcanisation chamber. The vulcanisation chamber may be an air oven, a microwave oven or a fluidised bed. The skin and foam are made of different but compatible materials such as ethylene-, propylene-diene or styrene butadiene rubbers, or neoprene (polychloroprene), nitrile (acrylonitrile) or natural rubber. The continuous profile is more versatile than profiles made by moulding processes. The process is more reliable than coextrusion of very thin skins on a full-sized profile.

Title: Reducing surface stickiness of water-soluble polyacrylamide hydrogels - by coating with a higher fatty acid or alkali salt
IPC: C08F2/00
Filed: 1977-10-20
Abstract: The surface stickiness of hydrogels of water-soluble acrylamide type polymers is reduced by coating the surface of the hydrogel with >=1 higher fatty acid or an alkali salt. Pref. 14-24C higher fatty acids are used at =0.01 wt.% esp. 0.05-0.001 wt.%, on total monomers. Process can be used with polyacrylamide, partially-hydrolysed polyacrylamides of water-soluble copolymers of acrylamide with other vinyl monomers. The fatty and (salt) may be added to the polymerisation system before the formation of the polymer. The process is esp. useful for treating the hydrogel before it is dried, to give free flowing dry prods. which are useful as adhesives for paper, thickeners, flocculating agents for water treatment and oil recovery agents. Addn. of the higher fatty acid material to the polymerisation medium reduces sticking of the hydrogel to the walls of the polymerisation reactor.
