Title: Container with limited opening
Inventor: TREBOT ALAIN
IPC: B65D47/24
Filed: 1987-07-15
Abstract: The container according to the invention comprises a bottle 2 having a neck 3 provided with a screw thread 4 on its outer surface and a stopper 7 closing the neck by screwing on this fast screw thread. At the base of the neck, a notched crown wheel 14 integral with the neck cooperates with a ring 11 interposed between the base of the neck 5 and the base of the stopper 10. The ring is driven in rotation by the latter. The notched crown wheel forms a ratchet wheel and the radially deformable ring 11 comprises notches forming retractable pawls. The screwing of the stopper is possible by the deformation of the ring up to the position of closure. Starting from this position, the opening is carried out over less than one turn because of the locking of the ring on the notched crown wheel.

Title: Machine for feeding handicapped people
IPC: A47G21/08
Filed: 1987-10-20
Abstract: A mobile device intended for feeding handicapped people no longer having the use of their hands. It consists of a base 1 onto which two plates 2 and 3 are fixed supporting the spoon mechanism 29 and the motor 5 which by itself powers both the spoon mechanism and the plate 11 by virtue of grooved pulleys, 9, 6 and 16 and round belts.

Title: Static electric generator with superconducting induction
IPC: H01L41/107
Filed: 1988-02-03
Abstract: The subject of the invention is an alternating, static electric generator operating independently of any other external energy source. The invention consists in causing piezoelectric, ferroelectric or magnetostrictive elements 1 2 to interact in a set of resonant cavities for the purpose of determining through ultrasonic waves a variable polarisation of these elements and hence an electric current of high intensity. The exciter elements 1 are ultrasonic wave generators, the elements 2 are resonators and create an alternating current 3. The elements 1 vibrate under the effect of a voltage produced by an RLC oscillating circuit 8 9 1. The energy dissipation in the oscillating circuit is compensated by electromagnetic induction with the aid of superconducting coils 10 forming a primary winding and with the aid of ordinary auxiliary coils 11 forming a secondary winding. The superconducting coils 10 tap off a compensation current from the production current 3 with no Joule effect or any other impedance, hence with no energy alteration of this current. This type of lossless tapping with the aid of superconducting coils can be performed on any variable current and in particular on the oscillating circuit itself.
