Patent FR-2524829-A1 (FR)
Title: Two-way hydraulic jack for bar bending machine - uses single action pump and head mounted opposite ends of cylinder in case forming oil reservoir
Inventor: TANDART JEAN-MARIE
IPC: B21D7/06
Filed: 1982-04-08
Abstract: The two way hydraulic jack for a bar-bending machine comprises a cylinder (1) in an oil reservoir with a cased single action pump (17) and a head (3) at each end. The pump has a ball distributor with one flow valve and one return valve. A lip seal (9) fits between the cylinder and the piston rod (6) at the head, its eventual non effectiveness being used as a stop to forward movement. A rear chamber (13) and a high pressure forward chamber (8) are fed via the distributor and a pipe (16) from the pump casing respectively. A stop ring (12) mounted on the rod is sited to the rear of a taper (29) and a second lip type piston seal (10) acts in a similar manner to the first to limit movement to the rear. A forward stop ring (7) has sufficient play on the piston to permit a laminar oil flow when the adjacent seal (9) becomes ineffective.

Title: Method and device particularly for improving the angular selectivity of an airborne radar used for ground detection
IPC: G01S13/524
Filed: 1982-05-14
Abstract: In a coherent pulse airborne radar with a low repetition frequency the direction @ in which the antenna is aimed can be altered in relation to the velocity vector @ of the aircraft 10 with respect to the ground 12. The radar circuits are controlled in such a way that the echoes sent via the ground 25 within the main lobe of the antenna are kept in the pass band of a preselected Doppler filter. The pass band of this Doppler filter is chosen according to the radiation pattern of the antenna so that all the echoes picked up in the main lobe 25 of the antenna are detected while the echoes picked up in the side lobes near the main lobe are rejected. In addition, provision is made for eliminating signals picked up in remote side lobes of the antenna in ambiguous isofrequency cones ( alpha 1, alpha 2). To achieve this, the repetition frequency of the pulses emitted by the radar is varied and the echoes with fluctuating frequency are rejected.

Title: Device which can be fitted to a vehicle, making it possible to sand in front of the wheels
IPC: B60B39/04
Filed: 1982-10-21
Abstract: The invention enters into the category of automobile accessories, which can be fitted to any vehicles with four or more wheels. Its object is to drop in front of the drive wheels of the vehicle the minimum amount of sand which will allow the driver to temporarily divorce himself from the problems of abrupt stopping or starting on an icy road. The system is composed of a conical tank with four panels 1 fixed vertically inside four angle brackets 2. One of the two wide panels of the tank forms, with the one opposite it, an outlet, permitting the passage of the sand. A movable trap door between two slides and actuated by a cable-pulley and return spring system, ensures the opening and closure of the tank. A pull cable ensures the link between the system and the dashboard.

Title: Device for obtaining image signals of electrical quantities across high-voltage insulation
Inventor: PERELLE MICHEL
IPC: G01R15/14
Filed: 1983-02-25
Abstract: A device for obtaining image signals of electrical quantities by transformer 3 across high-voltage insulation, using a low-voltage primary section 1 situated in a low-voltage environment and a low-voltage secondary section 2 situated in a high-voltage environment. The primary section 1 comprises a power supply circuit 1A providing, via the transformer 3, the electrical power required for the operation of the secondary section 2 in the form of pulses of power together with a receiving circuit 1B; the secondary section 2 comprises a power supply circuit 2A which converts the received pulses of power into voltage and currents and a data conversion circuit 2B which, in the absence of periodic pulses of power, is capable of short-circuiting the secondary of the transformer 3 with a mark-space ratio depending on the magnitude of the electrical quantity whose image at the level of the primary section 1 is required. The receiving circuit 1B measures the durations of the secondary short-circuits and derives an image signal from them. The invention relates to transmissions from high-voltage equipment.

Title: Device permitting the instantaneous interchangeability of the tool units and punch-holder cassettes on a press for crimping lugs in strip form
Inventor: CHAMBREY JACQUES
IPC: B23D31/00
Filed: 1983-10-25
Abstract: The invention relates to a device permitting the exchange of tool units and of subassemblies instantaneously. It consists of a base A solidly attached to the press on which a tool unit C is attached by means of a bolt B. The stripping device, with its sensitive contact 5, is mounted and dismounted instantaneously without adjustment and without screws or fixing clips. It is the two rods Y which act as guiding, centring and retaining means. Onto the tool unit C is mounted the support for the brake and the advance finger D, the mounting and dismounting of which are instantaneous. A star-shaped button 20 acts by gripping onto a U-shaped part which is deformed under this action and which, by means of a flat-to-flat bearing surface on the lug guide, locks everything in place. The strap brake 9 is instantaneously raised by means of a lever and cam and is automatically retained in the raised and lowered position. The advance finger 10 is constantly pressed against the lugs by means of a leaf spring 12 which pushes against the thrust cylinder 11. This leaf spring 12 also allows the thrust cylinder 11 to be retained with its advance finger 10 in the raised position. The punch-holder cassette E is withdrawn by manipulating (turning) the small wheel 13 or by bearing on the bolt B, as for the tool unit C, depending on the method adopted. The cassette receives the insulating punches 15 and conducting punches 16 which can be adjusted by means of two small jacks (thrust cylinders). The device according to the invention is particularly intended for interchaging the tool unit and punch cassettes.
