Patent FR-2323068-A1 (FR)
Title: Controllable hydraulic shock absorber - has hollow cylindrical actuator shaft which varies fluid flow to and from piston cavity
IPC: F16F9/48
Filed: 1975-09-02
Abstract: The hydraulic shock absorber does not generate high pressures in the regions adjacent to shaft seals, thus considerably easing the sealing design requirements. A cylindrical actuator shaft (1) slides axially in a cylinder (5) and has external ribs (11), just touching the internal walls of the cylinder. Inside the cylinder, the actuator shaft is bored out, forming a hollow (3) piston, containing a return spring (14). The other end of the cylinder is closed and extends inwards in the form of a cone (7) which penetrates the cavity (3) in the piston. When a load is applied, and the shaft is displaced, the gap between piston and cone progressively decreases and restricts transfer of fluid from the piston cavity to the cylinder cavity (8).

Title: Propulsion system utilising resultant of centrifugal forces of inertia - has unbalanced rotor which is alternately accelerated and decelerated
IPC: F03G7/10
Filed: 1975-11-18
Abstract: The propulsion system utilises a rotor with a mass attached to one side so that the rotor is unbalanced about its axis of rotation. The rotor forms part of an electrical machine which acts as an electric motor for one half of a revolution during which the rotor is accelerated. In the following half revolution the machine acts as a generator and the rotor is decelerated. The alternate acceleration and deceleration of the rotor produces a centrifugal force which acts continuously in the same direction and can be utilised as a means of propulsion.

Title: Stamping machine pneumatic height controller - has position sensors controlling air supply from accumulator to pneumatic cushion
Inventor: HAMANT LEON
IPC: B66F3/35
Filed: 1976-05-13
Abstract: A stamping machine has a plate (10) mounted on a pneumatic cushion (1), which acts as a lifting cylinder, which is inflated from a pneumatic accumulator (7) located under the framework. This raises the platform from a position of rest, supported on resilient pads (8, 9) on the framework, to an working position.

Title: Truing mechanism for grinding wheels - uses master profile and holder with probe follower and diamond trimmer
IPC: B24B53/08
Filed: 1976-10-29
Abstract: The grinding wheel trueing arrangement consists of a cylindrical holder (11) which can pivot about an axis (10) which is parallel to the plane of the grinding wheel (3).

Title: Dynamic volume measurement of moving cylindrical workpieces - has longitudinal and radial spring measurement rollers feeding generators producing pulse chains which represent dynamic length and radius
IPC: G01F17/00
Filed: 1977-03-25
Abstract: A roughly cylindrical log (1), the diameter of which varies along its length, is fed past a saw (6) in a sawmill. A longitudinal measurement roller or wheel (2) and a radial measurement spring roller (4) feed simpler generators (8, 9) which produce pulse chains representing the dynamic length traversed and radius respectively. A second longitudinal transducer (11) and impulse generator (10) are situated beyond the saw (6), offset from the first set by a fixed known length (26). A number of gates, switches and a difference counter (19) are linked together with these generators and with a volume measurement network (12). This gives a dynamic reaing of the volume traversed by the log past the first transducer set (8, 9) taking into account any direction changes, and also taking into account the offset between the transducer sets.
