Patent FR-2232154-A1 (FR)
Title: Parasitic correction in frequency and phase circuits - is for use in VHF communication and radio-location fields
IPC: H03D3/00
Filed: 1973-05-28
Abstract: Correction equipment for maintaining maximum usefulness of radio transmissions consists of a rectifying or detecting section to provide a voltage indicating the carrier level, a low frequency pass band circuit the output of which gives an indication of modulation depth and two further circuits, one a linear amplifier providing further outputs dependant on the received transmissions. The low pass band section has two short time constant circuits relating directly to the signal transmission, providing two symmetrical outputs each proportional to the positive and negative excursions of the carrier. Using these circuits to control threshold and comparative amplifiers. Phase and frequency distortion is corrected in v.h.f. frequency and phase modulated transmissions.

Title: Plastic container closed by heat sealed top - upper edge has peripheral ridges engaging underside of cover
IPC: B65D77/20
Filed: 1973-05-30
Abstract: The container is cylindrical and tapers towards its base. It is moulded in plastic or a metallic plastic and on its upper edges the two ridges are adjacent and define an annular groove between them. On the lateral edge of the rim is an outwardly projecting flange and this flange engages in the skirt of a shallow cover. Within the cover is a downwardly projecting ridge which lodges in the annular groove defined by the ridges on the container and provides a good seal, before the cover is heat sealed onto the container. When heat and pressure are applied the ridges coalesce without forming laterally projecting fingers.

Title: Track mounted brake for railway vehicles - pivoted beams engage sides of wheel and have vertically movable pivot
IPC: B61K7/04
Filed: 1973-06-18
Abstract: Two longitudinal braking beams are placed one on each side of a rail. These are fitted to arms ending in a common pivot below the rail. These arms can move vertically and are lifted simultaneously. In the raised position, the beams grip opposed sides of the rail vehicle wheel. The lifting power is produced by jacks, articulated to the pivoted arms so as to give equal motion on either side. The beams are fitted with grooved brake shoes, the upper part of which engages with the wheel. The beam pivoting point is housed in a slot, allowing the pivot itself to lift to a limited amount. The arms have slots whose upper faces engage the lower face of the rail support when the arms are raised, thus limiting vertical movement of the rails.

Title: Propulsive charge with partially inhibited bands - notably for use in anti-tank rockets
Inventor: DOIN BERNARD
IPC: F02K9/36
Filed: 1974-06-27
Abstract: Propulsive charge, notably for anti-tank rockets, comprises an assembly of bands of propellant arranged parallel to and around the axis of the combustion chamber. The bands of propellant have a parallelepipedal contour and are arranged annularly around the axis of the cylindrical body; they carry ribbons of a combustion inhibitor at the longitudinal external edges which bear against the internal wall of the body, with an intervening refractory lining. The bands form a single block with an internal ring, made of the same propellant and co-axial with the axis of the cylinder. They can be made by extrusion of a single block, by moulding or machining. Erosive combustion is prevented by the prodn. of an overpressure at the start of combustion followed by a gradually increasing press. during a part of the combustion period. The inhibitor helps to minimise the effects of the initial overpressure.

Patent FR-2251745-A1 (FR)
Title: High speed ball bearing for gas turbine - has corrected radius of curvature in outer ball track ring
IPC: F16C33/58
Filed: 1974-11-21
Abstract: The mass forces of the bearing walls increase with the cube of their diameter whilst their load carrying capacity is proportional to the square of the ball diameter. It is thus not possible to overcome the centrifugal force of a large diameter high speed bearing by increasing the bearing ball diameter. To increase the contact area between the ball and the outer track, the raio between the radius of curvature of the ball and that of the central zone of the outer ball track has a value of 1.005. This central zone supports the balls under normal load and running condition. The corresponding curvature ratio for the outer two track zones is 1.008. They support the bearing balls when excessive loads are applied to the bearing.

Title: Remote control system for TV receiver - uses frequency generator and motor drying control element to actuate selector switches
Inventor: CASSAN DANIEL
IPC: H03J1/20
Filed: 1975-02-12
Abstract: The remote control system for a television receiver is used to select the channel, adjust the volume and switch the receiver ON and OFF. It employs a frequency generator for transmitting radio or ultrasonic waves and an electric motor, which can rotate in either direction, associated with a single control element acting on the selector switching device. The control element is movable linearly, its movement ceasing upon the cessation of the frequency transmission. The frequency generator may provide a single frequency, with the rotation of the motor being reversed by micro-contacts when the control element reaches the end of its course, or the frequency generator may provide two frequencies, for rotation of the motor in respective senses.

Title: Filter press for sepn. of juice from grapes - with inflatable pressuriser working against perforated metal cage
IPC: B30B9/22
Filed: 1976-06-01
Abstract: Filter-press comprises a group of identical filters. Each has an external envelope which contains a perforated metal cage with holes for the passage of the expressed liq. The grapes to be pressed are pumped into the chamber delimited by the cage and by a pressuriser of rubberised cloth. The latter is inflated by compressed air; the grapes are pressed against the cage and the liq. flows through the holes to a trough from which it is evacuated to storage tanks. The solids, skins, pips and stalks, remain against the inside of the cage from which they are detached by the descent of a piston actuated by the introduction of compressed air. The piston is returned to its original position by the introduction of compressed air and a new cycle can be commenced. The filter is of partic. simple construction, it can produce a practically continuous flow of expressed liq.
