Patent FR-2248392-A1 (FR)
Title: Cupboard door latch - operates as a push button to release pivot arm inside
IPC: E05B63/12
Filed: 1974-10-22
Abstract: The door catch has a peg portion on the door which enters a socket buried in the frame which holds the peg secure in the closed position, which acts as a push button and releases the door when pushed. The socket houses a sleeve with an outer circular mouth containing a ring of balls which locate in a ring around the end of the peg and retain it. The sleeve moves against a coil spring to operate the latch device. The latter consists of a blade which is lifted up by a rod as it travels rearwards so as to swing over a spring loaded pivot arm which then engages a recess at the rear of the sleeve.
Patent FR-2295731-A1 (FR)
Title: Plugging means for body cavities during operations - made from polyurethane with a strong thread attached for withdrawal
IPC: A61F13/20
Filed: 1974-12-24
Abstract: Plugging means, or packings, for body cavities, for use during surgical operations, consist of a piece of foam (1), made from a plastic material which is physiologically inert, heat- and sterilisation-resistant, associated with a thread (2) which traverses the piece of foam from side to side. This thread, made from nylon, enables the packing to be withdrawn rapidly e.g. from the mouth once the operation is finished or at any other moment in case of need. The surgeon compresses the packing between the fingers and introduces it into the base of the mouth or other body cavity. On release it unrolls and conforms to the contours and reliefs so that a good dynamic sealing effect is assured during the whole of the operation under a general anaesthetic. The packing is easily placed in position and is capable of absorbing relatively large amts. of liqs. and secretions. When used in the mouth it protects the bronchial passages from debris and liqs. resulting from the operation.

Title: Engine utilising hydrostatic and mechanical forces - has immersed pistons displaced hydraulically and connected to weights producing moment
IPC: F03B17/04
Filed: 1977-04-05
Abstract: A circular disc (14) mounted on a central shaft (0) has two cylinders (1, 2) at its diametrically opposite ends. Each cylinder has a piston (1', 2') sliding in it and the pistons are connected by a hollow rod (3) which can slide in bearings (12) along a diameter of the disc. The disc with its associated assembly is immersed in a liquid. The hydrostatic pressure pushes the two linked pistons vertically down. The pistons are connected by a mechanical linkage with weights (A, C) so that the downward movement of the pistons causes a sideways movement of the weights (B, D). This produces a moment on the shaft which results in a rotation. After half a revolution the pistons are forced the other way and the process repeats.

Title: Regeneration of mixed bed ion-exchange resins - involves separating the two resins by elution and removing the interface mixture
Inventor: WIELAND GUNTER
IPC: B01J49/09
Filed: 1977-07-04
Abstract: After separation of anion- and cation-exchange resins by elution, the mixed interfacial zone, contg. particles of both resins, is taken off and not contacted with regenerant solutions. Mixed resin from the treatment vessel, when exhausted at the end of an operating cycle, is transferred to a regeneration tank in which, by upward flow of treated liquid, the light and heavy resin components are sepd. into two layers. The upper, lighter anion resin is displaced into a regeneration tank for brine regeneration. The mixed fraction is taken off into a holding tank whilst the remaining cation resin receives acid treatment. Used for the cyclic regeneration of mixed ion-exchange resin beds in which the exhausted resin mixt. is removed from the treatment vessel. Higher treatment efficiency and better liquid quality is obtd. because of lessened ion take-up by the mixed fraction of resin during regeneration.
