Patent FR-2102759-A5 (FR)
Title: Tube centering support - split sleeve provides coaxial support for tube in bore
IPC: F16L5/00
Filed: 1970-08-20
Granted: 1972-04-07
Abstract: A sleeve which grips the circumference of a tube and supports it coaxially in a bore, allowing relative axial movement between tube and bore as the sleeve is easily slideable in the bore; in this way, there is little danger of stressing and perhaps damaging tubes which tend to move relative to a support bore during a process, e.g., porous barrier tubes used for isotope separation in a diffuser assembly. Essentially the sleeve is made of a springy material and formed with an axially-extending slit in the sleeve wall to allow the sleeve to be sprung out against the inner wall of a bore when a tube is inserted into the sleeve to be tightly gripped by at least three axially-extending ridges.

Title: Coating treatment process control
IPC: C23C14/54
Filed: 1970-10-13
Granted: 1971-08-06
Abstract: The object to be coated and the metal or alloy used for coating are placed in a vacuum chamber and the latter is bombarded with electrons. On transference to the metal object, the vapour emits, on passing through the electron field, a characteristic radiation, which is analysed by a spectroscope, the reading of which having been previously calibrated experimentally to give a determination of coating thickness, may be used to effect an instantaneous control over the coating process.

Title: Through bolt for wall shuttering - has helical thread and nuts at ends have oval openings
IPC: E04G17/065
Filed: 1973-05-29
Granted: 1974-12-27
Abstract: The fixing for wall shuttering panels comprises a through tie-bolt (1) on which are helicoidal ribs, which mesh with similar thread in an anchoring nut (13). Between this nut and the shutter face is a spacing nut (23) which holds the shutter panel and allows fine adjustment of position. Each element is double threaded, ie the ribs and grooves are in two groups. The opening in the anchor nut (13) and spacer nut is oval to simplify location and fixing. The two shutter faces and liners are held apart by means of a tubular spacing sleeve inserted around the bolt (1). A double-handled nut is then threaded onto the free end and tightened up thus compressing the two shutter faces against the spacing sleeve. The shutters are therefore rigidly fixed at a specified distance apart.

Title: Concrete shuttering table - has superstructure supported by stiffening ribs on sectional girders
IPC: E04G11/38
Filed: 1973-11-23
Granted: 1975-06-20
Abstract: Support girders (1) are made of two U-or C-sections placed back to back and joined by cross-plates (4). Stiffing I-beams (6) rest on the girders (1). The plate is supported by extensible uprights (7) with flanges (8) formed of two U-shaped sections (9) placed back to back and joined together by means of iron fittings (10). The U-shaped sections (9) are mounted on the girders (1) by pins (11) inserted into any pair of holes (12) spaced equally apart along the sections (2) of the girders (1). The flange (8) of the girder is for suspending a shaft (15) held by a hinged pin (14) and a locking pin (14a) inserted into the pairs of holes (13) on the sections (9). The shaft (15) is connected at one end to girder by means of a strut (16) which can be dismantled.
Patent FR-2254234-A5 (FR)
Title: Liquid sampling device for a pipeline - utilises pressure difference generated by a venturi in the pipeline
IPC: G01N1/20
Filed: 1973-12-10
Granted: 1975-07-04
Abstract: The low pressure point from the venturi (6) in the pipe (C) is connected to the receiver (1) by the pipe (4), causing liquid to flow into the receiver through the pipe (2). The required sample is drawn off by depressing the platform (19) which operates the slide valve (34) and then placing a flask on the platform (19). The mouth of the flask is sealed by the plug (31) and provides a means of equalising the pressure in the receiver (1) with the pressure in the hole (32) via the pipe (33). This pressure equalisation allows the valve (29) to open allowing the liquid in the tube (26) to drain into the flask. Surplus liquid is previously drained off through the non-return valve (10).

Abstract: Rotary grinder embodies a symmetrical cross (8) with rollers (9) at each leg end, centrally bearing the grinder disc (3), the unit travelling along a sheet edge on two rollers to straddle successive corners and grind 45 deg. chamfers. This process and mechanism automates the edge chamfering of glass sheets. A rectangular sheet (2) workpiece traverses a table with a lever mounted cruciform carried grinder disc eash side. The discs are sprung to bear on the glass, and as the glass proceeds two wheels will engage each lateral edge until the cruciforms rotate the straddle the trailing corners.

Patent DD-228183-A5 (DD)
Inventor: MARTIN HENRY W
IPC: F01M1/10
Filed: 1983-01-19
Abstract: A centrifugal separator for separating contaminants from contaminated oil has an outer casing (10, 11) and a rotor (20) within that casing mounted for rotation about a vertical axis. Oil under pressure enters the rotor at one end and at the other end exits through jets (78) into a chamber within the casing which is normally filled with air. As the jets of oil impinge upon the inner wall of the casing, a small amount of air becomes entrained in the oil and as the oil flows to a sump, the air is gradually removed from the interior of the casing. In order to prevent a build-up of oil within the casing, which could interfere with rotation of the rotor (20), air under pressure is supplied to the interior of the casing by means of a float-operated valve member (113) so that while the valve member is normally closed, any increase in the oil level will cause the float (124) to rise with that oil level and thereby open the valve (113) to allow additional air to enter into the interior of the casing.

Title: Animated image display for moving observers - has fixed individually lit images, with stroboscopic and synchronous timing control and IR beam initiation
IPC: G09F19/22
Filed: 1987-04-24
Granted: 1989-01-03
Abstract: A succession of images separated by black space are placed along the side of an underground railway tunnel. Each image has its own individual lighting, and the images are illuminated successively in time by a system which is stroboscopically and synchronously controlled. The spatial interval between the images, and the temporal interval between their lighting are both calculated in relation to the speed of the observer in the train to obtain a total period of vision of the image and black space of 40 milliseconds. This corresponds to 25 Hz giving persistence of vision. The lighting sequence is started when the drivers cab crosses a photoelectric cell and is sufficiently retarded to avoid dazzling him. The beam of the infra red cell is slanted so that it does not respond to the spaces between carriages.
