Patent FR-2155846-A1 (FR)
Title: Textile packaging spindle - includes magnetic transmission of drive to spindle
IPC: H02K49/10
Filed: 1971-10-11
Abstract: A textile packing spindle carrying e.g. a bobbin on which the package is formed is secured to a rotatably mounted wheel carrying permanent magnets spaced around its periphery for co-operation with permanent magnets spaced around the periphery of a motor driven disc whereby the wheel and spindle are driven to rotate with the disc. Pref. the wheel or spindle are supported in magnetic bearings e.g. a semicylindrical magnetic cradle having permanent magnets at each end to provide a self-centering effect. The magnets on the disc may interleave with the magnets on the wheel and adjacent faces of the two sets of magnets may be of the same polarity to prevent contact between the disc and wheel magnets. The reduction in friction allows the spindle to be driven at high speeds allowing the textile to be taken up at the speed at which it is produced. Wear on the moving parts is also reduced.

Title: Method of forming sheets of e.g. steel - involves applying press. while supporting sheets at lines or points
IPC: B21D26/02
Filed: 1973-04-19
Abstract: Method of shaping sheet material e.g. steel, glass, plastic etc. into infinitely variable forms involves supporting sheet at random by means of point or line supports etc. and applying pressure at other similar points or lines according to materials used and forms desired. Classic stamp and matrix pressing is obviated. Numbers of supports or loads can be fixed for an operation or can vary and can be mobile or static and fixed to the sheet to permit sliding. A typical illustration is the formation of a semi-cone by forcing a sheet through a ring with a push rod.

Title: Machinery to move and stack sheet material - uses vacuum chamber lifted by pneumatic ram with air-flow rate control
IPC: B65H29/32
Filed: 1974-04-04
Abstract: A vacuum chamber (1) is attached to the shaft (4) of a pneumatic ram (5). One side of the piston (16) is permanently open to the atmosphere (7).

Patent FR-2279449-A1 (FR)
Title: Dispersion of solid particles in liq - stored in flexible container, by ultra-sonic vibrations from transducers in container
IPC: B01F15/00
Filed: 1974-07-26
Abstract: A process for dispersing solid particles in a liq. which is stored in a flexible container consists of irradiating and vibrating the liq. by the action of a field ultra sonic vibrations, created by an ultrasonic emitter attached to the flexible wall of the container or immersed in the liq. The emitter can be a piezo-electric, magnetic or electromagnetic transducer or a rotary generator. It is fitted in a fluid tight branch in the wall with an external cable to feed it and it may be surrounded by a receiver which has a flexible wall and which is filled with a liq. to transmit the vibrations, to protect the transducer from the liq. in the main container. Magnetically operated transducers in several containers may be fed by pulses, from a central distribution system, in a cycle. The process gives a permanent suspension of solid particles which separate in flexible containers e.g. calcium sulphate from liq. fertilisers. Such particles could adhere to the walls and to the bottom of a flexible container if they were not kept suspended. This would mean that frequent difficult cleaning would be necessary and the use of the invention avoids this.

The brush is mounted between two horizontal arms (7, 8) carried by a frame (9). These arms can pivot independently of each other around a common vertical axis. The arms are joined together by a flexible connection, consisting of spring leaves. Pivoting of the brush enables proper washing to be carried out to all vehicles, unlike installations using entirely vertical brushes. The brush is driven by a motor (12) mounted on the upper arm.

Title: Seismic streamer cable with depth control - has a stream-lined case containing the depth control elements
IPC: G01V1/38
Filed: 1975-05-07
Abstract: When the cable is towed, the control elements are so operated, that the cable is maintained in the required depth range. It has two depth control elements, separate and individually controlled. The first elements can only increase the depth, and the second only reduce it. It comprises further a depth detector generating an error signal, a function of deviation from the optimum required depth range, and a mechanism which controls the position of one of the control elements, so that the depth control unit moves with a vertical component and reduces to zero the error signal.
Patent FR-2310238-A1 (FR)
Title: Combined propulsion system for r d vehicles - has internal combustion engine and electric motor with interlocking mechanism for changing between them
IPC: B60L50/16
Filed: 1975-05-09
Abstract: The propulsion system for road vehicles uses both an internal combustion engine and a battery driven electric motor. The driver selects which power source shall drive the vehicle. A mechanical interlocking system ensures that it is impossible for both motors to be engaged at the same time. Furthermore the vehicle must be stationary before a change from one motor to the other can be made. By incorporating both types of motor in the same vehicle, and using common operating pedals, the advantages of the electric drive in towns and the internal combustion engine on open roads are combined.
Patent FR-2276187-A1 (FR)
Title: Tyre deflation detector - has piezo-electric unit whose signal is transmitted to receiver unit
IPC: B60C23/06
Filed: 1975-06-25

The crystal of the piezo-electric unit can be of polycrystalline ceramic material, e.g. barium or lead titanate and/or lead zirconate, and it can be housed in the wheel. There can be a detector pressed by the flat tyre as it passes over the point of contact with the road, in turn exerting pressure on the piezo-electric unit, and mounted in the air chamber between tyre and wheel rim or fixed to a wheel rim recess. The piezo-electric unit can be mounted in the tyre wall.
Patent FR-2319242-A1 (FR)
Title: Control of charged particle machining of substrate - is particularly for thickness control and uses substrate resonant frequency
Inventor: COUSSOT GERARD
IPC: H01L41/22
Filed: 1975-07-25
Abstract: A control system is for machining substrates, particularly piezo-electric substrates used as high frequency resonators, the machinining being achieved by ionic bombardment. Control of the ion beam is derived from a comparison of the resonant frequency of the substrate and a reference frequency, such that when the two frequencies match, the substrate thickness required has been achieved and machining stops. The control technique is particularly applicable to substrates intended to work in the 40 MHz to 500 MHz band. The substrate carries electrodes on both its faces leaving the central area free for bombardment, the electrodes transmitting the frequency generated during the process to detection and control circuits.
