Patent FR-2385004-A1 (FR)
Title: Hollow kinetic energy accumulator for vehicle - has flywheel containing liquid or powdered fuel and coupled to electrical generator
IPC: B60K1/04
Filed: 1976-12-27
Abstract: The energy accumulator is housed in a sealed casing closed by a lid. The elements of the accumulator are sufficiently strong to resist the centrifugal force when the accumulator is rotating. The container has a ball bearing and a sleeve integral with the spindle. Fuel passes along the passage in the spindle which extends up to the flywheel. Fuel which is centrifuged out is returned through a tube and drawn off by means of a pump.

Title: Circuit leakage test appts. - has warning light with selectable loads consisting of serially tapped resistors
IPC: G01R31/02
Filed: 1977-02-16
Abstract: A device is used for detecting current leakage in faulty domestic appliances. To use the device a current of five to seven times that normally applied is fed to the appliance and leakage is monitored by inductance through a transformed stage (3). A warning lamp (4) is connected between banks of serially tapped loads which are independently selectable by a gauged switch (2) to reduce the current loss effects of the lamp. The device is balanced by a complete transformer (1) operating on one side of the tapped loads. The construction only requires chemical battery power and is thus easily portable.

Title: Hydraulic inclination adjuster for height conveyors - performs pivot motion of conveyor and tipping of top part by use of hydraulic cylinders
IPC: A01D33/10
Filed: 1977-05-20
Abstract: The hydraulic inclination adjuster is also used for mechanically arresting parts of a height conveyor where the conveyor, in its working position, the conveyor assumes a position which leads upwards and sideways w.r.t. the connected mobile collecting - or harvesting implement. In its transport position it assumes a position which is collapsed in the direction of the implement. The pivot motion of the conveyor (1) and the tipping motion of its top (5) are carried out separately by means of two single acting hydraulic cylinders (14, 16) in sequence, connected in parallel to a hydraulic line (15). The tipping motion of the top part takes place in the vertical intermediate position of the bottom part (4) of the conveyor. The tipping motion of the top part (5) into the transport position and the pivot motion of the conveyor (1) into is working position takes place automatically under the action of gravity when the hydraulic line is switched to return.

Title: Removing mercury from aq. solns. - by sorption on a basic anionic exchange resin in presence of active chlorine
IPC: C02F9/00
Filed: 1977-06-02
Abstract: Solns. contg. Hg are purified by sorption of the Hg onto a highly basic anionic exchanger (I) in the presence of active Cl at 20-40 mg./l. (I) has a matrix of a porous 2-methyl-5-vinylpyridine (II)-divinylbenzene (III) copolymer. Pref. the process is carried out with movement (periodic or continuous) of (I) countercurrent to the soln. to be purified, and removal of spent (I) while adding an equivalent amt. of fresh (I). Used esp. for purifying waste waters from electrolysis cells or aq. sublimate solns. The presence of active Cl increases the dynamic capacity of (I) up to =44wt.% for Hg. Sorption cycle times can thus be increased, Hg concns. of =0.005 mg./l. in the effluent are achieved and the Hg is more easily recovered for re-use.

Patent FR-2369425-A1 (FR)
IPC: F16J1/24
Filed: 1977-10-28
Abstract: The piston (2), rotatable on a connecting rod (1) about its longitudinal axis (19), has a control element (10) capable of swivelling to and fro as a function of the swivel movement of the connecting rod (1). The control element (10) has two friction surfaces (11, 12), inclined towards the longitudinal axis (19) and enclosing an obtuse angle with one another. The one friction surface (12) interacts with a correspondingly formed friction surface in the piston (2) and the other friction surface (11) with a correspondingly formed friction surface on a contact pressure part (15). The contact pressure part (15) is arranged axially moveable in the piston (2) and its axial play (2s) is greater than the axial play (s) of the control element (10). A frictional connection of the control element (10) to the piston (2) comes about under the effect of the inertial forces of the contact pressure part (15) and of the control element (10). Because of the double cone shape of the two friction surfaces (11, 12) of the control element (10), large moments of friction are generated on the one hand, whilst on the other, owing to the different design plays of the control element (10) and the contact pressure part (15), a good separation of the interacting surfaces is always achieved at the end of the positive rotary movement of the piston (2), so that no return rotary movement of the piston can occur.
