Title: Hydroelectric generator rotor lifter - pneumatically operated pistons give lifting and braking action
IPC: F16D65/16
Filed: 1974-12-10
Abstract: Mechanism for lifting and braking vertical shaft rotors used in hydroelectric generating stations, consists of two pistons, one (24) superimposed on the other (23), in one cylinder (22) each having its own chamber formed by protrusions (28, 29). For braking the compressed air passes into the higher of the two chambers (36), pushes the piston (24) up such that the brake shoe (27) applies against the brake track (52) of the rotor (53). On releasing the brakes, the spring (45) pulls the piston to its rest position. For lifting, the pressurised fluid passes into the lower chamber (31) and forces both pistons up thus raising the rotor. On releasing the fluid pressure, the spring pulls both pistons to their rest positions.

Title: Wax treatment machine for vine grafts - has thermostatically controlled water bath temp maintained by electric resistance
IPC: A01G1/06
Filed: 1974-12-19
Abstract: The machine consists of a container in sheet metal (1) in which is held the water for the water bath, the water being heated by an electric resistance (2) controlled by a thermostat. The thermostat components and the electrical circuits are housed in a sheet metal box (6) located in front of the container and attached to it. The electrical resistance is capable of heating the water very rapidly, but the increase in temperature can be stopped immediately when the desired value has been obtained, through the absence of any metallic earth. Strict temperature control is obtained by a thermostat of which the sensor (12) is located between the two arms of the resistance, thus accurately monitoring the heat output. An inner bath (4) contains the paraffin wax, and rests directly on the bottom of the outer bath, on four feet (8) a few cms. above the resistances. It is provided with a cover (10).

Title: Refrigeration system with compressor - has compensating receiver accommodating gas in liquid state at constant pressure
IPC: F25B41/00
Filed: 1975-01-07
Abstract: Hot refrigeration gas passes via a discharge passage from a compressor to a condenser, while a liquid passage runs from the condenser to the evaporator and has a compensating receiver connected to it. A return passage leads the vapourised gas from the evaporator to the compressor and the condenser is exposed to the ambient temperature. A pressure-sensitive valve in the liquid passage between the condenser and the union to the receiver keeps the condenser at least partly saturated at all times during normal temperatures. Means are included for maintaining the gas liquid in the receiver and the liquid passage, and at a pressure substantially constant and lower than the discharge pressure of the gas from compressor to condenser in the discharge passage.

Title: Frequency divider with oscillator supplied with DC - has CMOS inverters deriving power only from signal supplied by oscillator
IPC: G04G3/02
Filed: 1975-04-30
Abstract: The frequency divider consists of two parts, and only one of these two parts requires a continuous source of energy. The second part of the frequency divider derives its energy from the signal being processed. When there is no input signal there is no power consumption. The oscillator is supplied from a dc source and it is coupled via a transformer with variable couplings to a rectifier. The rectifier is used to charge two capacitors that supply the first of two CMOS inverters. The second CMOS inverter is cascaded with the first CMOS inverter.

Title: Filing system with multiple strip index entries - has curved or polygonal cards for inspection from wide angle range
IPC: B42F21/00
Filed: 1975-05-15
Abstract: The filing system has the surface portion bearing the file index made in two or more non-coplanar strips. Two strips can form a straight dihedron, or a single strip may be rolled into convex or concave semi-cylinder, or there may be three of more strips to form a polyhedron. This facilitates searching through the titles from any angle or level, as each face bears the same index entry. The index file can be shorter than the face of the file unit against which it is mounted, and can have cavities at the ends. The overall shape of the file units can be rectangle with one face missing, and one bearing the index. Their base can have one or more holes nearer to the index end, and they can be arranged to fit in modules of rectangular shape, with one face missing.

Title: Telephone transit exchange with line detector for call charge pulses - has transistorised circuit connected to line and switch contacts at outgoing junction
Inventor: HODBERT FRANCIS
IPC: H04M15/10
Filed: 1975-10-23
Abstract: The telephone exchange equipment is used to retransmit call charge pulses when no special line is provided for such signals. The equipment includes an incoming junction, an auto-selector and an outgoing junction. A detector is added to the incoming junction line and a set of contacts is added to the outgoing junction line. The detector can detect a change in voltage in the line corresponding to call charge pulses. It has a transistorized circuit connected to the transit line (t). The change in voltage of the line (t) drives one (T2) of the transistors which in turn polarises another transistor (T3). Saturation of this transistor (T3) provides a voltage to a relay coil (R). The contacts of the relay (R) produces a signal for retransmission of the call charge pulses.

Patent FR-2319158-A1 (FR)
IPC: G06F13/42
Filed: 1976-07-20
Abstract: In the present method for transferring data between a control unit (SE) connected to a data processing system (DVA) and a data station (DS) containing an input/output unit (EA), each item of received useful information is acknowledged by the data station during the transmission of the useful information from the control unit (SE) to the data station (DS). If it is temporarily not ready for receiving the useful information, it signals this to the control unit. The control unit then outputs instruction words requesting the data station to output the status words until the latter is again ready for receiving useful information. During the transmission of useful information from the data station to the control unit, the control unit continuously sends instructions which request the data station to output useful information. The data station then sends either useful information or status words if there is no useful information.

Title: Delayed high speed sampling shift register - uses high density MOS memories working at several hundred megahertz and register is of series input and output type
Inventor: VIGEANEL PIERRE ANDRE ERNEST
IPC: G11C19/00
Filed: 1976-09-07
Abstract: A logic delay system has a high capacity and high memory density and a rapid sampling rate. The register has a series input and output form and includes several tens of thousands of memory cells working at a clock frequency of several hundred MHz. The number f individual component units is minimised by using high density MOS techniques. The system is intended to increase reliability whilst maintaining low manufacturing costs. The transit time for data in the delay circuit is a function of the time taken for the columns in the memory matrix to be 'loaded', ie the delay can be varied by altering the number of columns.

Patent FR-2367897-A1 (FR)
IPC: E05C21/02
Filed: 1977-03-22
Abstract: The tilt-and-slide wing has, at its top edge, a scissor mechanism, by means of which it is guided in a running rail (23) fixed to the frame. A bolt member can be displaced on the upper wing leg by means of an espagnolette (16) and can be brought into engagement with a counteracting bolt member on the upper frame leg. The upper locking is intended to make it possible to bring the wing into any sliding position without any difficulty. For this purpose, a link arm (25) serving as a bolt member is articulated on a cover rail (27) by means of a pin (26). On the other hand, the link arm (25) is connected via a pin (28) to a sliding shoe (24) guided in the running rail (23) which is fixed to the frame and which serves as a counteracting bolt member. A permanent connection is thus made via the link arm (25) between the movable wing and the stationary frame. So that the desired locking can be formed, there projects from the cover rail (27) a press-down boss (29) which is connected firmly to the espagnolette (16) and which cooperates with a catch (30) in the vicinity of the sliding-shoe pin (28).
