Title: Turn indicator self-cancelling switch - has steering column friction driven roller for return to neutral position
IPC: B60Q1/42
Filed: 1975-01-15
Abstract: A road vehicle self-cancelling turn indicating switch has an operating lever (2) which pivots abouts a spindle (4) in a frame (8') and is connected to a slide (10) which has one side (12) of circular form. A small roller makes contact with the circular side (12) of the slide (10) and a large roller (16), fitted onto the same spindle (28) as the small roller, makes contact with the steering column (18) of the vehicle. Two electric contacts (24, 24') and two leaf springs (22, 22') are used to close one of the two circuits to obtain turn indication. In one of the operating positions of the switch, the small roller rides on a raised part (44) of the circular side (12) of the slide (10).

Title: Fault detector for pneumatically pressurised electrical cables - requires four monitor lines to operate alarm and location functions
Inventor: FERLAY MICHEL
IPC: H02G15/28
Filed: 1975-04-04
Abstract: The detection system is for faults and their position in pneumatically pressurised cables. Losses in pressure are detected by simultaneous measurements of the pressure along the cable system. The design aims to minimise the number of cables associated with the individual monitoring stations. Four wires are included in the main cable sheathing. One pair form a 'go' and 'return' loop across which are connected the various manometer operated switches which are in the 'open' state for normal pressure. A third cable is connected to the remote end of the loop pair feeding directly back to a resistance bridge and null detector. The fourth wire feeds selected manometers and returns to a relay driven alarm system.

Title: Retractable airscrew for glider - with folding belt drive around parallelogram linkage to fixed engine in fuselage
IPC: B64C31/024
Filed: 1975-09-18
Abstract: The glider is fitted with a small engine (1) inside the fuselage at a point most favourable for the weight loading. The engine drives a belt drive (5) around four corners of an adjustable quadrilateral formed by four hinged formers linked at the corners by roller axes. This enables the drive to be extended out of the line of the fuselage, with the different angular settings of the formers still retaining the same belt length. One of the rollers (14) supports the hub of an airscrew which rotates inside a cowl (2) which acts as a duct. The cowl is attached to the formers and does not rotate with the screw. When the cowl is retracted it forms a smooth line with the fuselage for min. drag.

Title: Counter current liq. treatment of food prod. esp. curds - with liq. eluent via several troughs overflowing in cascade
Inventor: HUE JEAN
IPC: A01J25/11
Filed: 1975-10-16
Abstract: Plant comprises a set of horizontal troughs set in stepped paralle, cascade formation so that liq. flows along each trough and overflows at the end into the next trough below. Each trough is provided with stirrers and conveyor blades to push prod. along the trough counter-current to the flow of liq. As prod. approaches the end of each trough a scoop bails it up to the next trough above via the latter's overflow. The prod. is pref. foodstuff in the form of curds which is washed with a liq. eluent. The stirrers, conveyor blades and scoop of each trough are pref. fitted on a common, rotary shaft extending axially of the trough; all troughs shafts have a common drive with the scoops angularly staggered from trough to trough. Completely continuous, counter-current action over the full path of both gravity flow liq. and power conveyed prod. is achieved. Optimum conditions can be set quite independent of gravity flow.

Title: Shock absorber with pressure closing valve - has ball valve normally supported on perforated platform by spring
Inventor: SALLE P
IPC: F16F9/16
Filed: 1975-12-01
Abstract: The shock absorber consists of a piston (11) sliding in a cylinder (12) and enclosed in a flexible housing (34), protected by a metal cap (38). The piston (11) is provided with a bell valve (27) which is normally held off its seat by the spring (22) and supported on a perforated platform (32) by the springs (33). Under a steadily applied load fluid flows out of the chamber (28) past the valve (27) and through the holes (29). With a shock load, the sudden rise of pressure in the chamber (28) closes the valve (27) so that the fluid can only flow through the clearance (41) between piston (11) and cylinder (12). This causes a further increase in pressure in the cylinder (12) which resists the shock.

Title: Rankine cycle heat or cold generating system - has parallel condenser-exchangers operating on staggered cycles to give regular and continuous output to evaporate
IPC: F25B23/00
Filed: 1976-10-12
Abstract: The equipment generates heat or cold using the Rankine cycle, and has in a circuit containing a refrigerating medium an expander and an evaporator. It incorporates two or more condenser-exchangers (3, 4) in parallel and in which pressure increase is effected by heating from an independent source. The transformation cycles in the exchangers are staggered, to give a regular and continuous output to the evaporator (1). The staggering can be arranged so as to give partial balancing of pressure at the exchanger filling unit. The refrigerating medium can be delivered from the evaporator outlet to the exchangers to be filled by a pump functioning without appreciable back-pressure.

Title: Cabling or stranding machine - with guide elements supported on cables to reduce vibration and wear
IPC: D07B3/10
Filed: 1977-04-15
Abstract: In the mfr. of strands on a cabling machine, a deformable, elastic loop is formed of cables jointed at their ends to two support arms, mounted on two drive half-shafts. Between the two support arms, the tension of the two supple cables is controlled by the spring. Guide elements for the strand are mounted on the cables to support it during its passage through the machine. The tensions on the strand are reduced by reason of the supple mountings on the cables. Vibration and wear on the machine are diminished, and thus, noise and the possibility of overload are also lessened. The safety of the machines is improved, since the risk of rupture of the loops is also reduced.
