Patent FR-2472619-A1 (FR)
Inventor: HAYASHI CHIKARA
IPC: C23C14/34
Filed: 1979-12-27
Abstract: The appliance consists of a chamber (10) which is fitted in an electrically insulated manner with a cathode support (22) for a cathode (20) with a cathode material layer (24) to be sputtered. An anode (26) is fashioned so as to retain a substrate (28) to be coated. The surfaces (30, 32) of the cathode material layer (24) and of the substrate (28) are parallel to one another and are arranged so as to be tilted with respect to a horizontal plane. The appliance is operated with an inert atmosphere having a pressure of 6.5-1.3.10<-3> mbar and a voltage of 800 V. When the substrate is coated by cathode sputtering, a uniform film is formed thereon, and the cathode material layer (24) can be used up virtually completely, without pieces dropping down owing to fracturing and thus being lost to the operation.

Title: Handle for sports racquet with reservoir of talc - talc is ejected onto handle through holes in sliding reservoir and handle
IPC: A63B49/08
Filed: 1980-01-31
Abstract: The handle (a) contains a reservoir of talc (b), in a hole in its extremity, which can be ejected through holes (e1,e2,f1,f2) onto the handle. There is a spring (c) on top of the reservoir and the reservoir is held in place by a screw (d) with a central hole. The end of the reservoir (b1,b2) is widened out and corresponds to grooves (a1,a2) in the handle. The pressure of the thumb on the cover of the reservoir makes the openings in the reservoir coincide with those in the handle, allowing the talc to escape.

Title: Motor scooter float frame conversion - has pivoting friction roller converting wheel drive to propeller and raisable floats for selective use
IPC: B60F3/00
Filed: 1980-03-12
Abstract: Two floats (3,4) are connected by spaced traverses (13,34) which provide a seating for a longitudinal frame (2) which in turn carries the motor scooter using bolting plates (12). The frame can be in a high position where end fingers (13) pierce holes in the top of the traverses, the wheels are above the water line, and a pivoting friction roller (47) is in contact with the rear wheel which drives the propeller (54). On land, the fingers (13) penetrate lower holes in the traverses, the friction roller is folded away, and the scooter wheels are in contact with the ground between the two floats.

Title: Noise making cover for bombs - has hollow spaces filled with material of similar density and or hardness to cover wall
IPC: F42B12/76
Filed: 1980-04-09
Abstract: The envelope generates noises and is for aircraft and mortar bombs. The outer wall (5) is smooth and the inner is divided by a square pattern to give elements in relief (3). These are parallelepipeds, separated by hollow spaces (4), themselves parallelepipeds of the same dimensions. The relief parts (3) do not contact side stops and the hollow spaces are filled with material of density and/or hardness similar to that of the wall. An internal smooth surface (6) is thus formed, and inside this is placed an explosive filling.

Title: Motor vehicle axle drive housing - mfd. from rectangular steel tube with two slotted sides radially expanded
Inventor: NEUMANN BERTRAM
IPC: B21D7/04
Filed: 1980-05-22
Abstract: A rectangular steel tube is provided with oblong slots on two opposite walls. When the slotted section of the hollow tube is expanded outwards, a round chamber is produced to form an axle housing for the location of the differential gear. A hydraulically operated (22) expansion tool has two pairs of reaction rollers (6) between which the axle tube is located. Two jaws (3) which engage the tube slots are located between the fixed location rollers (6). As they are forced outwards by the cylinder action, the first stage of the axle tube forming is obtained.

Title: Cutting of microscopic spiral groove on shaft journal - uses axially reciprocating stone applied to rotating shaft during alternate strokes
Inventor: PINEAU JEAN CLAUDE RENE FRANCO
IPC: B24B19/02
Filed: 1980-08-07
Abstract: The process uses an abrasive stone (6) to cut a microscopic spiral groove on a cylindrical workpiece (7), to provide a micro-turbine oil seal at e.g. the location of a shaft journal in a housing aperture. The workpiece (7) and the stone (6) are subjected to relative reciprocal displacement parallel to the axis of the workpiece while it is rotated, being brought into contact and separated during succeeding inverse movements. The cutting machine may use an hydraulic device (28) to move a stone-holder (2) relative to the workpiece, and includes a mechanism (11,21,22,24) which automatically compensates for the wear of the stone.

Title: Luminance and chrominance separator circuit for colour TV receiver - contains comb filters comprising logic and delay circuits to generate bi-linear transformations and digital A=D converters
Inventor: MORAILLON JEAN YVES
IPC: H04N9/78
Filed: 1981-04-27
Abstract: An A/D converter receives a clock input which is four times the frequency of the chrominance sub carrier to sample a composite video signal and provide parallel outputs. The converter output is also applied to the parallel inputs of a rejection filter for the chrominance and carrier and also to the parallel inputs of a band pass filter. The filters are comb filters and comprise adders, subtractors and delay circuits to generate the requisite bi-linear transformations. They operate in digital sampling modes to produce a digital value for the luminance signal on one set of parallel outputs while the chrominance sub-carrier is produced on a second set of parallel outputs.
