Title: Vehicle drive with optional regenerative braking - uses engine or flywheel only and engine and flywheel modes with automatic control
IPC: B60K6/10
Filed: 1975-07-18
Abstract: The electronically controlled vehicle drive system operates in three modes, the first with the engine only connected to the drive, the second with a flywheel only connected, and the third with both connected. Force coverters are brought into operation so that during connection and disconnection, the speed of the flywheel is maintained above a determined low level. The force is applied to the flywheel only when the speed of the engine exceeds a given low level, by means of a centrifugally actuated device, which is in turn, hydraulically operated by a fluid system. The flywheel is driven by the engine, when a reduction in speed occurs and when the ratio between the two speeds is less than 2.5 to 1.
Patent FR-2288514-A1 (FR)
Title: Formed products film coating - using aqs solutions of water-soluble cellulose ethers
IPC: A61K9/36
Filed: 1975-07-31
Abstract: Formed products (esp. medicinal tablets, pills, pastilles, pellets or granulates) are film-coated by applying an aqueous solution or suspension of at least one water-soluble cellulose ether (pref. methylcellulose, hydorxypropylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose and/or hydroxyethylmethylcellulose) in water as the sole solvent, using a standard coating process. The coating is pref. carried out in a ventilated coating pan or drum or in a Wurster apparatus. Use of water as the sole solvent avoids health, fire and explosion hazards and costs associated with organic solvents, the cost savings being greater than the penalties of higher energy costs because water is less volatile than organic solvents. Film-coating with aqueous dispersions of acrylic resins is known, but this necessitates the addition of water-soluble additives if the coated product is intended to disintegrate in the mouth and the application of a protective sealing layer if the product to be coated is water-sensitive; these measures are not necessary when coating with aqueous solutions or suspensions of cellulose ethers.
Patent FR-2320656-A1 (FR)
Title: Electromagnetic screw-nut system for vertical axial movement - esp. for removing and replacing control rods of nuclear reactor
IPC: G21C7/12
Filed: 1975-08-06
Abstract: Device incorporates a tubular body, a magnetic screw inside the tubular body, a magnetic nut outside the tubular body and a device limiting the axial movement of the screw. The tubular body is made of magnetic material and is smooth inside. The screw constitutes the rotor of a polyphase asynchronous motor, the stator of which is fixed outside the tubular body. The magnetic nut consists of two annular pole pieces around the wall of the tubular body with a winding and a magnetic armature. The inner surfaces of the pole pieces are threaded, the pitch corresp. to that of the screw. The pole pieces are spaced apart by an amount equal to a whole number of pitches. The thread of the internal screw as well as that of the inner surfaces of the polar pieces is filled with a metallic non-magnetic, or an insulating material so that the surfaces opposite the screw and the tube are smooth and continuous. The electro-magnetic units are easily accessible from the exterior and can be dismantled or replaced without contact with the interior of the tube. The power necessary for rotation is reduced to a min. The degree of freedom of the screw in the tube is very great, allowing its free fall by simple cutting of the magnetic circuit and the effect of gravity. No reducers, rails, guides, pinions etc. are necessary, all rotary and translatory movements being brought about electromagnetically.
