Patent FR-2252941-A1 (FR)
Title: Spring mounting for automatic railway coupling - has intermediate part fitted by torsion spring to spring assembly
IPC: B61G7/10
Filed: 1974-12-02
Abstract: Consists of an intermediate part placed, at the end of prestressing, in the spring assembly which is first placed in compression. Usually this is d-one by special gear - mechanical or hydraulic presses, and takes a long time, so the intermediate part is fitted by a flexible element, preferably a torsion spring, indirectly by a base plate or directly to a moving part of the spring assembly. When the spring assembly is first compressed it undergoes a compression value greater than the required compression. The patent avoids this by a simple screw system for pre-compression to the required value.
Patent FR-2252468-A1 (FR)
Title: Flexible three dimensional open cell covering material - has number of interlaced profiled strips with slots
IPC: E04F15/10
Filed: 1974-12-09
Abstract: The flexible flat material is used as covering for roads and ground. The open, three dimensional structure of the covering material is filled with ballast such as sand, soil or grass. The flexible ground produced is suitable for carrying vehicles and pedestrians and it can be used, for example, for covering racecourses. The profiled strips used can be made from textile fibre reinforced rubber, polyurethane or PVC. The cover improves the surface draining and load carrying capacity of the ground. The interlaced system of strips has a first kind of strips made from flexible material and the second kind of strips. These strips are keyed to each other so that the first strips from horizontal members and the second strips are arranged vertically. The strips are parallel to each other.
Patent FR-2295386-A1 (FR)
Title: Tunnel furnace with heating by electrical resistances - which are housed in grooves in hearth roof elements protected by removable plates
IPC: F27D11/02
Filed: 1974-12-16
Abstract: Refractory brickwork forms the lower and upper base blocks of a tunnel furnace and houses intermediary refractory elements which form the side walls of the tunnel and a series of elements assembled side by side longitudinally to form the hearth and roof of the furnace. These elements in the form of plates have parallel transverse grooves, the depth of which is at least equal to the dia. of resistances which sit in the grooves, close together. The resistances are of the hairpin type, each leg sitting in adjacent grooves and the tails projecting through a notch formed between the upper and lower base blocks, to the outside of the furnace. Each resistance has its individual control to vary the temp. profile along the tunnel and the resistances are connected in series. Refractory plates cover the grooves of the hearth and roof elements to protect the resistances, these plates sitting in grooves made in the side-wall elements of the tunnel so that they can be removed. Hairpin tubes of high temp. steel can also be housed in the transversal grooves of the elements to act as cooling coils for certain parts of the furnace. Construction is used in electrically heated tunnel furnaces of square or rectangular cross-section with width 50-1000 mm. An extremely regular high intensity heating of hearth and roof is obt. because grooves are close together and can also give varied temp. profile along furnaces as resistances have individual control. The resistances are easily changed even during operation by non-specialised personnel.

Title: Ball screw for machine tool use - has transfer passage with lip to pick up balls and bent through right angle
IPC: F16H25/22
Filed: 1975-03-12

Title: Automatic sound or luminous alarm with manual control - uses transistor controlled electromagnetic relay to actuate alarm
Inventor: GUYADER ANDRE LE
IPC: G08B17/06
Filed: 1975-06-30
Abstract: The automatic alarm with manual control has a sound or luminous warning device The automatic alarm is permantly connected to an alternating electrical supply.

Title: Moulding and extrusion method - for fluidising crushed powdered material which does not flow easily under gravity
IPC: B28B5/02
Filed: 1975-08-29
Abstract: A method of fluidising crushed, pulverised, comminuted powdered or other particulate solids, with or without added liquid, that will not flow readily under gravity has been developed to enable this material to flow through an aperture either as an extrusion or to cause it to conform precisely to the shape of a mould. The material is inserted into the top of a hopper having an aperture at its base through which the material is discharged under gravity to a surface or into a mould. The material is subjected while in the hopper to one or more vibrators arranged to effect vibration of the material in the intended direction of flow through the hopper. This causes the material to flow freely through the hopper, and effecting relative movement between the hopper and a surface or mould to effect the withdrawal of the material discharged from the hopper.

Title: Vehicle spare wheel carrier - is wire cage under chassis, swung out sideways and lowered to ground for easy removal
IPC: B62D43/04
Filed: 1976-02-06
Abstract: The arrangement for holding a spare wheel (2) for a motor car uses a wire cage (3) mounted under the chassis, i.e under the floor (1) of the luggage boot, so that the wheel is retained horizontally without occupying any luggage space. This cage has two wire arms forming a V shape, supported by a wire rod (4) across them. The two arms are bent, to match the shape of the wheel, with ends hooked over. When a catch (16) holding them is released,the whole cage can be swung out about a vertical pivot (7) and the V part swung down with the cross rod (4) forming a pivot, to rest on the ground for simple removal of the wheel. The end of the rod remote from its pivot, carries a roller (6) which travels along a horizontal curved guide track (14) when the cage is swung out.

Title: Constant speed control for universal motor - has tachometric alternator incorporated into shaft, and diode compensating hysteresis
IPC: H02P7/292
Filed: 1976-07-23
Abstract: The constant speed control, for a universal motor, has a tachometric alternator (2) incorporated into the motor shaft (1) and connected to a thyristor control circuit (4). A diode (5) connected into the circuit, compensates for the motor's hysteresis arising because the current it receives is not DC but pulsed. The diode increases the motor efficiency. A protection circuit consisting of a rectifier and resistor circuit, is connected between the supply network and the tachometric alternator to prevent the motor experiencing damaging acceleration if the cable connection to the tachogenerator fails.

Title: Electric hoisting machine safety system - detects imbalance of three=phase supply using magnetic ring around each conductor
IPC: H02H1/06
Filed: 1977-03-21
Abstract: A three-phase motor (1), causing movement of the hoist is fed by three-phase conductors (2, 3, 4). Each conductor is encircled by a magnetic torus (5, 6, 7) which transmits a signal to a flowmeter (8), the output of which is fed to the coil of a relay (9), activating a switch (10). At the same time, each conductor (2, 3, 4) feeds a rectifying bridge (11), charging a capacitor (12) of high capacitance. Normally, the capacitor is charged, and the switch is open. If one of the three-phase conductors is open-circuited, the imbalance created in the flowmeter results in the switch closing, and thence the capacitor discharging into the control coil (13). The control coil then activates the safety function by, e.g. cutting off the supply to the motor. Instead of a relay, a transistor or thyristor may be used.

Title: Prepn. of non-alcoholic beer from low concn. must - giving beer of density about double that of normal beer
IPC: A23L2/38
Filed: 1977-07-29
Abstract: Prepn. of a non-alcoholic beer comprises the following to a must of low concn. an amt. of hops is added twice that required for a normal beer. The stirred brew is adjusted to pH 4.3 and boiled for an hour and a half to eliminate part of the protein fraction. The complex nitrogen fraction is then reduced by digestion with a proteolytic distance for a day. The must is then cooled to 8 degrees C, 2 g/hectolitre of maltolysine is added, and the mixture is strongly oxygenated. It is then left for 24 hrs. cooled to about 1 degrees C, and 1 litre of yeast/hectolitre is added. The must is then allowed to ferment until a well frizzled head is formed accompanied by a temp. rise of about 3 degrees C. The beer is then cooled to about 1 degrees C, filtered through kieselguhr, and pumping to pre-bottling tanks. Ascorbic acid is added at 2 g/hectolitre followed by passing in CO2 under pressure over a day until a saturation of 6 g/l is obtained.
