Patent FR-2258331-A1 (FR)
Title: Silo and filling and emptying device - raises silo on ramp and releases to produce material freeing shock
IPC: B60P1/00
Filed: 1974-01-18
Abstract: The container (1) has four rails (8) attached to its base, together with cross-pieces (8). The rails are carried by rollers or wheels (12) mounted on supports (9, 10). The container is slightly angled. A geared motor (21) drive a cam (19) which moves a push-rod (16) carried in a guide (17), the end of the push-rod (15) bearing against the cross-piece (8). The motor thus raises the container in an inclined direction, until the shape of the cam releases it to fall against end stops (13). The roller on the end of the push-rod against the cam, is spring mounted to assist the release. The shock so cause either helps pack the material into the container or helps dislodge it out.

Patent FR-2266367-A1 (FR)
Title: Speed slaving device for electromagnetic transmission - has one or more self-induction coupling elements
IPC: H02P29/00
Filed: 1974-03-26
Abstract: An adjustable L/C circuit compensates for variable speed perturbations such as hysteresis, surge and phase shifts. This circuit is followed by a gate device which controls the functioning of a square-law pre-amplifier which in turn actuates a voltage/current power converter. This converter excites the self-induction coupling element. When used with 2-speed electric motors the device permits automatic switching from low speed to high speed and vice versa by means of a tachometer. Voltage comparison and the output from the L/C circuit is effected by a differential comparator followed by an error multiplier-amplifier.

Title: Dual fuel engine with automatic fuel selector - applicable to road vehicles with power take-off from engine
IPC: F02D19/06
Filed: 1974-12-31
Abstract: The fuel selection system is intended for use with vehicles carrying concrete mixers or road drills and with a power take-off to permit the use of the propulsion engine to drive the machinery. To comply with French taxation requirements, an untaxed grade of fuel may be used for supplying power to the machinery but this grade must not be used to propel the vehicle along the road. Hence two separate fuel tanks are provided either of which can supply fuel to the injection pump. The invention describes a pneumatically operated system which automatically delivers the correct grade of fuel according to whether the engine drives the road wheels or the machinery.
