Title: Automatic automobile gearbox control - by storing gear change information allowing kick down
Inventor: SIBEUD JEAN-PAUL
IPC: B60W30/18
Filed: 1974-04-24
Abstract: The system of automatic gearbox control uses known devices and controls and electronic circuits of a closed loop variety to: (a) release the clutch; (b) immobilise the gearbox; (c) to put in a memory the selected speed and other information and operate clutch and gearbox appropriately thereafter. Both the gearbox and clutch are electrically operated. The gearbox change order may be suppressed and the memory cleared to allow a new ratio selection either manually, by "kick-down" on the accelerator, by an automatic device operating when the engine operates below a set level, completely automatically or semi-automatically.

Title: Declutchable manual controller for valve shaft - has screw shaft and rotary sleeve lockable together
Inventor: MAEDER CLAUDE
IPC: G05G1/08
Filed: 1974-07-05
Abstract: A shaft is moved along its axis automatically by a jack comprising a circular membrane with two circular washers permitting attachment to the shaft. Movement is caused by pressurisation of a chamber in a casing. A manually rotatable driving mechanism comprising a tube coaxial with the shaft is locked by screwing to a shaft extension through a hollow shaft which is inside it for automatic control. For manual control the tube is turned with the aid of arms to screw or unscrew the hollow shaft on the thread of the control shaft extension until a slot aligns with a slot in the casing, when a locking arm is inserted. The shaft is then moved by rotation of the tube.

Title: Unidirectional chopper to convert DC input - uses only main and auxiliary thyristor and series diodes
IPC: H02M1/06
Filed: 1975-01-29
Abstract: The unidirectional chopper converts a continuous dc input (11,12) into a pulse output (15) which is passed via an LC filter (33,34) to a load (36). This is achieved using only two thyristors. The input is applied to two series diodes (31,32). The first diode is shunted by an inductor (27) and the main thyristor (13). The output (15) is taken from the junction between the main thyristor cathode and the first diode anode. The main thyristor is shunted by the series combination of an LC commutating circuit (23,24) and an auxiliary thyristor (21). A diode (40) is anti-parallel to the auxiliary thyristor.

Title: Hydraulic pump delivery regulator - has sliding element pressure-actuated to connect pressure to drain during variable part of revolution
IPC: F04B49/02
Filed: 1975-03-28
Abstract: The arrangement is intended for rotary hydraulic pumps in which a spring-loaded regulator element is axially slidable in a bore under the action of the pump delivery pressure whilst rotating synchronously with the pump relative to the bore, the element being provided with a profilated recess via which the pump pressure can momentarily flow to drain during a processively longer period of each revolution as the pressure further exceeds a pre-determined limit. The arrangement is such that, in its initial position, the element fully closes the drain connection, and when the pressure displaces the element against its spring, the profilated recess opens the connection over a progressively increasing rotational angle so as to reduce the effective pump delivery per revolution.

Title: Electrolytic recovery of zinc from alkaline solns. - using electrolyte flowing at a speed which removes zinc from cathode
Inventor: JACQUELIN JEAN
IPC: C25C5/02
Filed: 1976-06-09
Abstract: The soln. is at least temporarily driven at a speed which physically removes Zn particles from the cathode. The soln. is pref. driven at constant speed so the Zn is deposited on the negative electrode but is then removed and carried away by the soln., but the speed may be reduced for the deposition stage. The cathode is inside an asbestos sleeve which allows the electrolyte to reach the anode but not the Zn particles. Normally, the Zn is deposited as a sponge or a non-uniform layer and can be difficult to dissolve. The invention removes the Zn by a simple method which avoids the complex and expensive use of mechanical stripping.

Filed: 1976-06-24
Abstract: A method and an apparatus for producing crimped filament yarns, said apparatus comprising at least one first twister member and at least one second twister member, each of said twister members having a work surface made of a synthetic rubber having a relatively small friction coefficient therebetween. These twister members are arranged so that their work surfaces cross each other at a selectable angle in contact relationship to provide at least one crossing zone for nipping therebetween at least one thermoplastic filament yarn which is fed to twist this filament yarn between the contacting work surfaces successively and at the same time to urge this filament to discharge from this crossing zone successively as the twister members are driven. This method and apparatus allow filament yarns to be imparted desired false-twisting effect, practically without being damaged and without causing uneven twists, at a high operation rate of 800 - 1000 meters per minute.
