Patent FR-2400108-A1 (FR)
Title: Driving head for coal face cutting machine - has front mounted pivoting lever on which spiral grooved cutting rollers are mounted
Inventor: PENTITH GERALD RICHARD OLDHAM
IPC: E21C35/20
Filed: 1977-08-11
Abstract: The coal face cutter drive head consists of extended arm (s) which mounted at right angles to them, have a lateral suspended pivot spindle. The arm(s) carry at least one cutter roller with spiral grooved periphery. Pref. the coal cutting machine has mounted at the extended central pivoting arm, at either end a cutting roller (23) with opposite rotating drive movement. The peripheral cutter bits are mounted in a helical configuration. The gap between the cutter rollers is bridged by cover (48) with lateral folded side plates. An auger type feed screw is forwarding cut coal onto an extended endless conveyor in the longitudinal working direction.
Patent FR-2402484-A1 (FR)
Title: Centrifuge bowl with improved abrasion resistance - having grid formed from wedge-shaped bars with transverse and vertical mounting in conical bowl
Inventor: ASNER V I
IPC: B04B7/18
Filed: 1977-09-08
Abstract: Centrifuge bowl for a sieve type centrifuge has a conical shape. It is constructed from segments each of which is in the form of a grid formed from a series of rods with wedge or trapezium shaped cross section. The narrow aperture between adjoining rods is mounted on the inner surface of the bowl and this serves to support the filtered material. The edges of the segments on both sides have reinforcement ribs mounted along the conical profile at the stress points of the segments. These ribs consist of a protective plate which in the longitudinal direction extends over the complete impact length of the segment on the inside of the bowl and which overlap the adjoining segments. Used in sepg. materials esp. abrasive ones such as coal and sand. The construction of the connection joints of the centrifuge ensures that premature failure of the weld connections and reinforcement ribs does not occur.

Patent FR-2405565-A1 (FR)
Title: Connection strip for distribution boxes - has cranked section with cogged semicircular convex end lockable with box wall
IPC: H01R9/24
Filed: 1977-10-10
Abstract: In the connection strip for electrical distribution boxes, the space available for the introduction of wiring into screwed terminals is minimal. The strip design eases the access problem and minimises the time required to make connections. The strip, carrying orthodox screwed terminals along its length, may be rotated about a line parallel and close to its own axis. This allows in-service position and a position in which access is improved. Each end of the strip has a cranked section with a cogged semi-circular convex end engaging and lockable with a mating section bolted to the box wall.
Patent FR-2407826-A1 (FR)
Title: Transfer printing process partic. for cotton or PVC - employs colourless resin applied between support and colourant sheet
IPC: B41M5/035
Filed: 1977-11-04
Abstract: Transfer printing with sublimable colourants is effected by interposing an unpigmented colourless resin between the support material to be coloured and the sheet carrying the colourant. The resin can be applied to the support before transfer printing e.g. only to the parts requiring to be coloured, except for a slight overlap. It can be applied by a separate heat transfer step using an intermediate support previously covered with resin. Alternatively, it can be applied to the sheet carrying the sublimable colourants, printing being carried out in a single operation. Polymerisation of the resin can be effected at the same time as the transfer printing. If an intermediate sheet is used, it can be hydrophobic or very slightly hydrophilic, and the same sheet can be used several times. The process can be used on supports with surfaces of varying kinds, being partic. adapted for use with textile materials made from natural cellulosic fibres such as cotton, or with PVC plastic.
Patent FR-2408368-A1 (FR)
Title: Lotto number checking device - uses grid over which is placed card punched out by player
IPC: A63F3/06
Filed: 1977-11-09
Abstract: The check card for comparing the winning numbers of a lotto game with the players' cards consists of a square or rectangular card in the middle of which are vertical rows of numbers identical to those on the lotto board. The player has a punch with which he punches out holes in the card. A square hole in the first horizontal row of figures indicates the number of the grid in the card underneath. The numbers are checked by placing the card on the board so that the square hole shows the grid number, and so that the edges of the card are parallel to the rows of numbers on the board.

Patent FR-2410589-A1 (FR)
Title: Rail vehicle with externally flanged wheels - having tyres shrink fitted onto bodies which are located on axle by stepped seating
IPC: B60B37/04
Filed: 1977-11-30
Abstract: The vehicle has wheels designed to run on rails with restricted side movement. The restriction can be external flanges (21) rubbing on the rail sides. For a rubber tyred vehicle, tyres, turn horizontally and contact vertical guides. The running surface of the tyres is inclined inwards. Each wheel has a body on to which a tyre is shrunk and held on an internal seating which prevents the wheel moving outwards, by acting as a stop.
