Patent FR-2201170-A1 (FR)
Title: Propellent charge structure - with prismatic powder sections in a moulded plastic coating
IPC: F02K9/24
Filed: 1972-09-28
Abstract: The propellent charge blocks are provided with an internal, longitudinal, prismatic channelling with a star-shaped cross-section and are notably intended for the propulsion of missiles. The plastic core has a number of prismatic channels around its periphery, each channel having the same cross-section as the sections of powder. The latter are placed in the channels and kept in position by thin ties. The cylindrical assembly is placed in a metallic mould and both ends are closed by stoppers; the lower stopper has a reservoir for the coating which consists of a resin, of the type which polymerises in the cold, and a refractory filler. The mould is mounted on a support and rotated arounds its own axis and also around an axis perpendicular to the latter. This causes a rapid migration of the resin into the annular space between the internal surface on the mould and the external surface of the core with its powder sections in position. Perfect homogeneity of the supporting resin envelope is obtd. in the short time required for the polymerisation of the resin. When this has taken place the assembly is withdrawn from the mould and the core extracted from the propellent charge structure thus obtd.

Title: Signal phase angle measuring device - uses repetitive waveform shaped for phase comparison with input signal
IPC: G01R25/00
Filed: 1974-03-11
Abstract: The device is for diverse studies such as internal combustion engine timing to the control of the sweep of oscilloscopes. A sawtooth signal derived from the repetitive reference signal is applied to the input of an operational amplifier circuit which acts as an inverter with unity gain. The second input of the amplifier is connected to a reference voltage such as zero volts. A switch connects the amplifier stage input or output to an input of a comparator to reverse the sign of the phase angle. A potentiometer provides a signal whose phase angle is required. The comparator output is connected to two transistors which conduct depending on the phase difference and the output is read on a galvanometer.

Title: Cleaner for water straining grid - to prevent blockage of water channels esp. canal sluices
IPC: E02B8/02
Filed: 1974-03-15
Abstract: A straining grid in a water channel, is cleaned by a horizontal comb, the teeth of which are forced between the vertical bars of the grid in an upstream direction, and which is then drawn up to a point where the debris may be discharged into a collector. The comb is swung in during downward travel, or a pivoting arm, guided by castors which are diverted by a deflecting plate into 'U' section runners downstream of the vertical runners which guide the comb during upward travel; travel is actuated by a rack and pinion mechanism. Pref. e.g. alternate grid bars are truncated for 1/3 of their height, to provide a by-pass in the event of blockage of grid.
Patent FR-2268734-A1 (FR)
Title: Moving strip tension regulation system - has tension detector actuating potentiometer to vary individual roller motor speeds
IPC: B65H23/188
Filed: 1974-04-24
Abstract: A number of motor-driven rollers at intervals haul the strip along and a first variable potentiometer is connected to a part of each motor and to a power source. All first potentiometers are coupled together for simultaneous adjustment, while a second variable potentiometer is connected to another part of each motor and to a power source. A strip tension detector reacts to variations in tension and is coupled to each of the second potentiometers, varying the speed of an individual motor and its respective roller independent of the others. Each detector can have a feeler bar capable of angular movement and situated where the strip is guided or diverted. Thus when tension alters it moves in the direction of the strip and actuates the second potentiometer via a coupling.

Title: Measurement of deformations of electrically insulating body - using embedded coil forming oscillatory circuit coupled to tuned oscillator
Inventor: PIETERS BERNARD ALBERT
IPC: G01B7/24
Filed: 1974-07-05
Abstract: Device comprises a deformable electromagnetic coil (2) embedded in the body (1) and which follows its deformations, at the same time forming an oscillating circuit. The distributed capacity of the coil (2) augments that of a condenser (5) mounted in parallel across the coil. The device includes an oscillator (3) whose frequency is slaved to that of the oscillating circuit (2). The oscillator (3) is of the tuned circuit type with the oscillatory circuit being coupled magnetically to its resonant circuit (4) through a face of the body, the oscillator typically being outside the body while the oscillating circuit is inside the body, or vice versa.

Title: Rotary machine driven by potential energy - has weights driven around circular guide placed eccentrically of horiz. shaft
IPC: F03G7/10
Filed: 1974-10-22
Abstract: Circular guides (4) are supported on a framework (5) and are in vertical planes. The guides carry a number of weights (1) which can move round the guides and which slide on radial spokes (2) fixed rigidly to a shaft (3). The shaft may be moved by mechanical means away from the centre of the guides and in a horizontal plane so that the shaft and guides are eccentric in a working state of the machine. The eccentricity ensures that the torques applied to the shaft as the weights move about the guides is unequal on opposite sides of the shaft, thus causing the shaft to rotate.
Patent FR-2261964-A1 (FR)
Title: Method of forming reel of welding wire - involves using a guide moving in an arc of a circle
Inventor: JAHNS E
IPC: B65H59/00
Filed: 1975-02-21
Abstract: As the wire leaves the straightening machine (1) it feeds through a guide (2) moving in an arc (5) of a circle, the wire forming the radius, with the straightening machine at the centre. The wire is led to the reel (4) for winding, and, as it forms a layer (3) on the surface, the guide (2) moves until the wire reaches the other end of the reel. Here, the guide reverses and a new layer builds up. At the other end of the reel, reversal occurs and the procedure is repeated. Winding tension is kept constant by the guide lagging or leading from a neutral position.

Title: Flying cutters for spirally welded pipe mfr. - has serrated cutter wheels hydraulically clamped at each and operated by scissors action
Inventor: POTTIER MICHEL ALBERT
IPC: B23D25/04
Filed: 1975-04-17
Abstract: The spirally welded pipe (T) is manufactured as a continuous process and cut into lengths by flying cutters. These are mounted on a carriage travelling with the pipe and at the same speed. The cutters are serrated wheels (45), a set of three rotating freely in a holder (37) fitted to an arm (25) on each side of the pipe. These arms are cranked (26, 28) and swing about pivots (27) in their upper sections. The arms are clamped onto the pipe by an hydraulic cylinder (V), this imparting a scissors action to both arms together. As the pipe rotates (g), the serrated cutters shear through the metal.
Patent FR-2307900-A1 (FR)
Title: Storing and feeding yarn at constant tension - by wrapping around drum rotated via clutch controlled photoelectrically
IPC: B65H51/22
Filed: 1975-04-18
Abstract: Yarn is wrapped around a polished steel drum to form a reserve winding, the yarn being advanced on a conical surface so that each turn of yarn is moved axially along the drum. A photosensor detects the number of turns of yarn on the drum and controls a clutch and electric brake to rotate and arrest the drum accordingly. Pref. the yarn is fed axially from the drum. The method is used in advancing weft yarns in a loom. The yarn is formed into a reserve and advance under constant tension, thereby eliminating breakages.
Patent FR-2309077-A1 (FR)
Title: Frequency selector control on radio receivers - has electronic tuning control switching from one band through to second band
Inventor: BAILLARD ANDRE
IPC: H03J5/24
Filed: 1975-04-25
Abstract: The apparatus is used for control of frequency for radio receivers. It is used where wave-band switching may be required or tuning through from one band to another. The design allows selection of frequencies within one band without altering the components required for the other bands covered by the receiver. A control signal derived from one waveband oscillator is fed to a combined amplifier and amplifier clipper (2) providing a constant amplitude variable frequency square wave. A further amplifier stage (3) feeds a LC circuit having a resonant frequency slightly higher than that of the original control frequency. Detection of this provides a d.c. level which varies the tuning value of a variable capacitance diode.
