Patent FR-2549286-A1 (FR)
Title: Delay timer for automatic gearbox.
Inventor: GALLAY DOMINIQUE
IPC: F16H61/08
Filed: 1983-06-15
Abstract: Device for timed control of an electromagnet placed in a motor vehicle gearbox, which electromagnetic engages a gear of the said box to obtain a modification of the ratio. The control channel includes safety contacts which, since they include no hysteresis, can, when they are closed, lead to jolts in the progress of the vehicle. To prevent this, a delay-timer system has been placed in the control channel in series with the contacts and the electromagnet. Its particular feature is that it offers a large resistance to the electromagnet when the safety contacts are closed and this throughout the time of the delay and a very small resistance at the end of delay in order to permit control of the electromagnet. If one of the safety contacts opens during the delay, the latter is automatically reset to zero.

Title: Hydropneumatic device making it possible to convert the static forces of some liquid masses into kinetic forces capable of producing energy
IPC: F03B17/00
Filed: 1983-06-29
Abstract: The present invention relates to the means for producing energy from forces accumulated inside liquid masses under pressure. The device consists of a cylindrical wall 1 of low height, of another concentric wall 2 which is slightly higher, on the top of which will be fixed an arch-shaped element 4 intended to contain a gaseous mass under pressure, the side 5 of this second wall will be located inside and below the level of the wall 1 and will be fixed from place to place on support points which will at the same time be anchorage points intended to reinforce the construction. When the device is ready to operate, with the central mass under the pressure of the liquid, the space located between 1 and 5 will contain a second liquid mass which will be under the pressure of a gas the level of which will be slightly above the wall 1. When equilibrium between the various forces has been achieved, the value of the pressure of the gases will depend on the magnitude of the central liquid mass. Pipes 7 which pass through the wall 2 at its lower part will serve to transmit the pressure forces exerted on the liquid mass 6 to the outside world, the production of energy will result from a series of states of equilibrium and of inequilibrium.

Title: Stop piece and mechanism for closing gate leaves
IPC: E05F5/00
Filed: 1983-07-07
Abstract: The invention relates to devices of the type of a mechanism for closing gate leaves. This invention consists of a stop piece equipped with a mechanical device allowing one or both leaves of a gate to be blocked using one's foot. It comprises a support piece 7 forming a stop 12, 13 equipped with a cam 4 which pivots between two stubs 10. One or other of the leaves slides on one or other of the edges of the cam to end up in abutment. Depending on the position given to the cam, the latter blocks one or other of the leaves or blocks just one or both elements simultaneously by virtue of the stub 14 fixed on one of the leaves. Amongst the most beneficial applications of the invention, mention may be made of its use as a positioning (hanging) accessory for installing new gates positioning and adapting existing gates.

Title: Improvement to handling and storage means. Stackable mini-containers which may be instantaneously disassembled (or assembled)
IPC: B65D21/02
Filed: 1984-05-07
Abstract: Stackable mini-containers which may be instantaneously assembled or disassembled to enable their transport cost to be lowered. The invention relates to the manufacture of handling and storage equipment which considerably reduces the handling operations and which may be used as a storage, dispatch and sales unit. This equipment consists of a bottom 1 and of four sides (such as 6 and 17 which may be assembled or disassembled without any tool or additional part and which are perfectly interchangeable). Since it may be produced by injection moulding of plastics, it is lightweight, solid, of low cost and produced by moulds which are extremely simple to machine. The assembly of the five constituent elements is carried out by rotating the sides through 90 DEG with respect to the bottom 1. Two of the opposite sides 6 are made integral with the adjacent sides 17 by means of a device sliding in a slot 9, the sides 6 being maintained in the vertical position by the elastic action of stop-pieces 13. This equipment is particularly suited for the storage of spare parts, of partial assemblies, for the despatch of products (sales units) and for their handling by their buyers.

Title: Back pack for aquatic outings
IPC: A45F3/04
Filed: 1985-11-28
Abstract: Back pack adapted for transporting equipment in an environment which may be damp or aquatic. The invention relates to a back pack with two superposed compartments which are independent and permeable, one of which contains a leaktight bag. It consists of two compartments separated by a partition 3 which can be folded downwards, by virtue of a slide fastener (zip) 4, the compartments being permeable to water and easily accessible from the outside via a lace 12 on eyelets, at the top, and a slide fastener (zip) 5 at the bottom. The lower compartment contains and protects a leaktight bag 2 in which a camera, a towel and food, for example, may be kept dry. The upper compartment 1 receives the technical equipment (rope, for example) which will get wet during the manoeuvres. The device according to the invention is intended particularly for transporting technical and photographic equipment during aquatic outings such as speleology or the descent of waterfalls, while remaining capable of easy conversion into a conventional back pack.
