Title: Electrical actuating mechanism for rail points - has motched drum chain-driven from double acting ram with two balance levers
Inventor: CRUTSCH LOUIS
IPC: B61L5/06
Filed: 1974-10-03
Abstract: The mechanism has a drum with a horizontal axis and a notch driving an actuating rod for the points. The drum is driven by a coaxial sprocket. A chain engaging with the sprocket has its ends attached to the rods of a double-rod double-acting ram whose axis is at right angles to that of the drum, and which is supplied by a motor-driven pump. Two rocker levers mounted on opposite sides of the drum and coupled together by a bar pivot on horizontal axes. On one end of each rocker lever has a sprocket meshing with the chain, and the other end has a roller running against the drum so as to drop into the notch in one or the other of the two end positions of the mechanism, thus locking the points in place.
Patent FR-2287399-A1 (FR)
Title: Dish washing installation - has dishes in boxes carried on smooth surface links of conveyor chains
IPC: B65G17/08
Filed: 1974-10-07
Abstract: The system comprises inlet and outlet conveyors, possibly a closed loop, driven by suitable motor and pulleys. The conveyors are based on a trough (16) carried on suitable supports (17). In the centre of the trough is formed a narrow rectangular depression (18). The upper length (8) of the driving chain links runs in this trough with link connections in the depression. The lower, return length (8b) passes beneath the trough. The boxes (4) containing the dishes are carried on the links. The smooth surfaces of the links allow the links to slide beneath the boxes, if a blockage stops the boxes moving.

Patent FR-2311919-A1 (FR)
Title: Electrically operated door opener - has linear electric motor whose speed of shaft displacement is limited by hydraulic damper
Inventor: KUNDIG PETER
IPC: E05F3/10
Filed: 1975-05-21
Abstract: The electric door opener has a partitioned casing (1) forming an outside chamber (14) and an inside cylindrical perforated chamber (9) with one way valves (10, 11) at either end. Both chambers are fitted with hydraulic fluid, and a fluid reservoir maintains a constant fluid supply (15). A longitudinal shaft (6) has a piston (7) at one end which travels inside the perforated cylinder. At the other end the shaft forms the core of a linear electric motor (20) and the drive to the door opening linkage. The linear motor causes a displacement of the shaft whose piston forces oil through the perforations from the inside to outside chamber. The restriction of oil flow limits the speed of the shaft displacement.
Patent FR-2278591-A1 (FR)
Title: Tensioned closure for plastics lids - esp for drum- or barrel-type containers
IPC: B65D45/32
Filed: 1975-06-26
Abstract: A device for fixing plastics, esp. polyolefin, covers to containers has an easily twistable wire ring having a tensile strength corresponding with the pressure exerted by the merchandise to be filled into a container. The wire is arranged on bearing surfaces subtending an obtuse angle with the outer wall of the cover and is twisted to cause diminution of the cross-section. The device is esp. suitable for reliably closing barrels (e.g. with 120 1 capacity) without deformation of cover of container, and covers with rel. small diameter are used. The wire has largest possible diameter but rel. low tensile strength (e.g. 3 mm dia. tensile strength 10 kp/mm2 for 120 1 barrel).

The reverser (3) is mounted on the shaft of the input pulley of the speed changer and it is joined to the differential (4) by a shaft almost perpendicular to the clutch output shaft. Final drive is by two half shafts (51) (52) and the whole assembly is mounted directly on to the engine.
Patent FR-2326241-A1 (FR)
Title: Mobile cabin for spray-painting long objects - incorporates air washer with fixed wash-liquor gutter, acting also as hydraulic seal
Inventor: DAUDENTHUN MICHEL FERNAND ERNE
IPC: B05B14/468
Filed: 1975-10-01
Abstract: The object is fixed and the spraying is done in a mobile cabin, contg. an air inlet and a fan ensuring continuous circulation of air in the cabin, bringing in clean air and discharging contaminated air to a washer. Plant incorporates a fixed gutter extending along the path of the cabin, receiving the discharged wash-liq. The washer is attached to the mobile cabin, and the gutter is used as a hydraulic seal between the air outlet from the washer and the fixed discharge to atmos. In prior art, the fluid-tightness between the gutter and the air in the cabin is achieved by a flexible strip, which can be rapidly fouled, and also the washer may be under the cabin and move with it, using a lot of water and weighting the cabin. The invention, by using a fixed gutter, allows the use of as much liq. as required, and by using the gutter as a seal, resolves very simply the problem of fluid-tightness.

Patent FR-2307683-A1 (FR)
Title: Adjustable load regulating brake valve - with screw adjuster for valve spring operated via tooling holes
IPC: B60T8/18
Filed: 1976-04-16
Abstract: The load regulating valve operates with a spring loaded servo piston (28) which modulates the output brake pressure w.r.t. the load sensor setting. In order to provide a controlled set point at which the modulation begins, with a variable elasticity of the springs in a mass production process, the valves are fitted with adjusters. These comprise screwed adjusters (35) operated via tooling holes (33) from the outside of the valve. The adjusters alter the spacing between the valve element support (16) and the bracing piston (28) at the other end of the spring. This alters the spring tension.
Patent FR-2311353-A1 (FR)
IPC: F16H59/04

Title: Non-skid vehicle chain - comprises six equal links coupled at sides by rigid hinging bars
IPC: B60C27/04
Filed: 1976-07-28
Abstract: The non-skid vehicle chain comprises a set of U-shaped stirrup links coupled together. It comprises six equal links (3), coupled together at the sides by rigid bars (2, 2') at an equal distance from the link side or opening. The bars hinge where they join the links.
