Patent FR-2244190-A1 (FR)
Title: Dual gauge cine projector with transport sprocket - has a single selector with switch coupling for motorised sprocket change
IPC: G03B1/50
Filed: 1974-09-19
Abstract: The projector incorporates a manual selector which is mechanically coupled to the changeover system for the film gate, claw and film guide which are closely grouped about the film gate. The selector is coupled to a switch and to a control element. These couple the film transport motor to the axially movable dual sprocket so that it is moved automatically into the correct axial position for the chosen film gauge. The design is claimed to be simple and economical to construct and to simplify projector operation by combining all gauge changeover functions in a single control.

Title: Controlling perfusion or transfusion fluid flow - by moving lever to compress flow tube at several points simultaneously
IPC: A61M39/28
Filed: 1975-02-07

Title: Low temp. heat engine - burns hydrogen and oxygen in closed system in presence of atomised water
IPC: F01K25/00
Filed: 1975-04-07
Abstract: Hydrogen is introduced into a combustion chamber through a central nozzle. Oxygen is introduced through an annular nozzle surrounding the hydrogen nozzle. Water is injected through a primary atomiser surrounding the two fuel nozzles and through secondary nozzles placed along the length of the combustion chamber. The injected water reduces the temp. reached and so makes it possible to use existing known materials of construction. The steam produced by combustion and vaporisation of the injected water is taken to a steam turbine. The condensate from the turbine is returned from the hot reservoir by a feed pump to the water atomising injectors in the combustion chamber.

Title: Electrical space heating plate - provides uniform heating over the plate surface when vertically mounted
IPC: H05B3/26
Filed: 1975-05-29
Abstract: The electrical plate is employed for room heating and normally wall mounted. The electrically resistive heating element itself is printed on a rigid porcelain or porcelain covered metal sheet. The design is such that the plate (1) in a vertical position does not become unevenly heated which occurs with a uniformly distributed element. The element is designed such that the heating effect is reduced towards the upper edge of the plate by increasing the elements width (3) in this direction hence reducing its resistance and power dissipation. The increase in width may be linear producing triangular shaped elements or non-uniformly producing a curved element loop.

Patent FR-2318946-A1 (FR)
Title: Electrolytic recovery of zinc from alkaline solns. - using electrolyte flowing at a speed which removes zinc from cathode
Inventor: JACQUELIN JEAN
IPC: H01M8/06
Filed: 1975-07-21
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.
