Title: Hydraulic throttle device with permanent flow channel - has channel gap related by mathematical formula to fluid properties and dimensions
Inventor: KATS A Y
IPC: G05D7/01
Filed: 1975-09-24
Abstract: A throttle for the hydraulic circuit of a programmed machine tool or follower mechanism has a circular housing (1) with a groove (5) around part of it, into which fits an insert (6). The latter is of a higher linear coefficient of expansion then the material of the housing. The housing and insert are ring shaped and enclose a rotating cylindrical member (2), leaving a gap (7) between. The width (h) of this gap is given by a formula relating the viscosity of the fluid handled, the length of the gap, the density of the fluid, and the pressure drop inside.

Patent FR-2346622-A1 (FR)
Title: Flow limiting valve for pipe line - uses sudden fall in downstream pressure to cause valve closure
IPC: F16K17/28
Filed: 1976-03-31
Abstract: The flow limiting valve has a cylindrical body (1) with top and bottom flanges. The valve head (6) is attached to the valve rod (4) which slided in the guide bush (5). The valve is normally held open by the spring (11) which sets on the lever (10) which, in turn, actuates the spindle (9) and lever (7). A fork on the end of the lever (7) engages a pin (8) on the valve spindle. When there is a sudden drop in pressure downstream of the valve, due to a pipe burst, the pressure difference across the valve head is sufficient to overcome the force of the spring (11) and close the valve. The valve may also be closed when required by the pneumatic or hydraulic actuator (12).

Title: Locking device for railway points - has pivoted elements connecting two fixed elements with elastically deformable element gripping vertical roller
IPC: E01B25/26
Filed: 1976-04-29
Abstract: The device described may be used to lock a moveable object esp. a railway point in two extreme positions without a stopping point between them. A pivoted element connects two fixed elements situated in front of and behind the pivoted element. The mobile element (6) has one or more deformable elastic elements (20) at its point which partially embraces the periphery (35) of a roller (36) pivoted about a vertical axis (37) integral with the fixed element (2). The point of contact (51) moves in the shape of a cycloid along the elastic element (20) which is subjected to a sinusoidal deformation. A control system modifies the position of the point of contact (51) and the contact force between the elastic element (20) and the roller (36). This may be achieved by using two parallel ports (41,42).

Patent FR-2343145-A1 (FR)
IPC: E05F15/53
Filed: 1977-03-03
Abstract: The switching device (10) for a pneumatically actuated double-acting cylinder (11) is suitable for the drive of swing doors. A five-way two-position valve (12) controlling the connections between the pressure-medium source (32), pressure-medium run-off (35) and two cylinder connections (16, 18) has a closing member (26) loaded by a spring (27) in the direction of an initial position (28). The closing member (26) is loaded counter to the spring (27) by the pressure in that cylinder connection (18) which is not bled in the initial position (28). The change-over of the valve (12) into the working position takes place by the build-up of a dynamic pressure in a cylinder connection (18) during the movement of the swing door, so that the switching device (10) works purely pneumatically and the swing doors can also be opened from intermediate positions.

Patent FR-2392200-A1 (FR)
Title: Coloured concrete mfr. - by mixing the colours with the mould release agent applied to the shuttering prior to casting the concrete
IPC: C04B40/00
Filed: 1977-05-25
Abstract: Coloured concretes are made using colouring materials on the concrete shuttering in the form of mould release agents. When the concrete is cast into the shuttering and vibrated to place it completely into the mould, the colour is transferred to the concrete surface. Used in the mfr. of architectural concretes. The method avoids the need to use sufficient colouring matter to colour the whole block of concrete. It also avoids the need for using transparent colourless mould release agents. Problems of colour change at the edges of mating shuttering pieces are avoided. Ghosting due to excess vibration is avoided. Colour uniformity can be achieved. Colour variation can be deliberately applied giving artistic effects.
