Patent FR-2222187-A1 (FR)
Title: Synchronising system for packing machines - has assembly machine chain coupled to chain of machine producing bases
IPC: B23Q7/06
Filed: 1973-03-23
Abstract: The system is for use between one machine producing bases, and another assembling the sides of a packing onto the bases. The chain with lugs driving the work through the assembly machine is mechanically coupled to that of the machine making the bases. The chains are coupled by a further chain passing around respective drive wheels of the two machine chains. The assembly provides synchronisation between the two machines which may thus be assembled in a single machine which require no manual handling from operators.

Title: Therapeutically active tannin fractions prepd. - from Cupressus sempervirens fruits by extracting with solvents
IPC: A61K8/97
Filed: 1973-04-20
Abstract: Tannin extracts are produced by subjecting Cupressus sempervirens fruits harvested 4-8 months after flowering of fruits remaining on the tree and harvested 16-20 months after flowering to extraction with an aq. solvent, treating the total extract or the evaporation residue of the extract with ca. 90 vol. % alcohol in order to separate therapeutically inactive weakly condensed tannins from the desired strongly condensed tannins, and collecting or recovering the resulting insoluble therapeutically active strongly condensed tannin fraction. All of the therapeutic activity of Cupressus sempervirens tannins (used in the treatment of venous disorders) is in the strongly condensed tannin fraction. The new process provides a simple means of separating the active strongly condensed tannins form the inactive weakly condensed fraction.

One end of the billet is melted while the other end holds the starter piece which is withdrawn by rotating the billet. The billet may be an electrode or a separate non-consumable electrode may be used. The products are semi-circular ingots which can be welded together to form rings for prodn. of e.g. high pressure vessels or cement furnace straps.
Patent FR-2232396-A1 (FR)
Title: Friction butt welding of tubes - by revolving ring between butt ends under pressure
IPC: B23K20/12
Filed: 1973-06-07
Abstract: Pipes of large dia. for pipelines are butt welded together by rotating a V-shaped ring which fits in the V-gap of the chamfered pipe ends. When the frictional heat has softened the metal near the ends, an axial force is exerted to weld the pipe ends together and the press the ring outwards. The heavy pipes need not be revolved, only the small ring which can be stopped quickly when desired. This method produces much less internal flash on the pipes than if the pipes are rotated.
Patent FR-2234908-A1 (FR)
Title: Appts to measure the efficiency of a ball player - speed and precision are recorded using radar and photography
IPC: A63B63/00
Filed: 1973-06-28
Abstract: Speed and precision of aim are both recorded automatically. A target, which may be a light capable of being moved horizontally and vertically, is placed in a surface plane which forms the goal area. The ball, covered with a metalised paint, is hit towards the goal and its speed measured by a radar detector as it passes through the surface. Precision of aim is recorded using an instant print camera or a video tape recorder, with a correction factor applied to allow for the ball's trajectory and distance from the goal area. The speed may also be measured by determining the time elapsed during the passage of the ball.

Title: Rapid action fixing element - is plastics or metal plug with slotted insertion end
IPC: F16B21/08
Filed: 1974-03-21
Abstract: A shaft (1) connects two inwardly facing abutments (4, 7) spaced at a distance equal to the combined thickness of the materials to be joined.

Title: Turbine or windmill rotating about vertical axis - with cam to align hinged blades to suit fluid flow
IPC: F03D3/06
Filed: 1974-10-04
Abstract: The turbine rotor has a shaft (A) which is mounted with its axis vertical and carries two discs (D). These discs support four curved blades (V1)(V2)(V3) (V4) which can pivot on pins (P1)(P2)(P3) (P4). The two blades (V1)(V2) are held facing the wind by the stops (O1)(O2) but as the rotor rotates the blades are made to pivot by a cam operated by the rotor so that the blades offer the least resistance to the wind when moving against the wind direction. This attitude of the blades is shown by the blades (V3) and (V4). As each blade completes a revolution the cam changes the blade attitude to the position (O1) to receive the force of the wind.

Title: Tank filling equipment - has two-stage float detector controlling inlet valve
Inventor: COURANT JACQUES
IPC: B67D7/36
Filed: 1974-11-06
Abstract: The equipment prevents spillage from fuel tanks. In the pipe connecting the source (9) to the tank (1) is a valve (A) with a body incorporating a seat, against which there works a plug movable between the fully open and tight shut positions. One plug face is subjected to the pressure downstream of the seat, which tends to move it into the open position, while the other is part of a chamber connected to the upstream side of the seat by a calibrated orifice. The plug is spring-loaded to shut. A detector with float (B) is mounted in the tank. When the contents of the latter reach a predetermined level (N1) they bring the float from a rest position, in which it opens the overflow to an active one where it shuts if off. A hand control may be used.

Title: Vacuum packed meat etc. squeezed by compressed air - to eliminate juice-collecting cavities from package and product
IPC: A22C7/00
Filed: 1975-05-12
Abstract: Meat or fish portions are filled into packages which are then enclosed in a chamber to be subjected first to vacuum condition to extract air from the packages and then immediately to compression by compressed air in order to close up all spaces between portions inside a package and between the packaging material and the portions. Factory prodn. of vacuum packaged raw foods, e.g. meat and fish, esp. hams, pressed into packages ready for cooking. Obviates air inclusions in and between packed portions. The sudden pressing by compressed air closes up all spaces which would otherwise fill up with juices during cooking and result in loss of quality when the juices were subsequently frozen. The pressing operation is applicable to a wide range of sizes and shapes of packages, not requiring a press mould limited to a single type of package.
