Patent FR-2160609-A1 (FR)
Title: Locating welds in strip - in a continuous strip rolling line
IPC: B21C47/26
Filed: 1972-11-17
Abstract: The weld zones are detected by two coils which have partially split circular cores and are arranged in an offset manner. When a weld zone passes the gap in a coil, the flux change produced is concentrated at the heat-affected zone. The two coils are in two arms of a bridge circuit which compares changes in impedance in one coil w.r.t. the other. False signals are thus avoided and the weld zone is located accurately.
Patent FR-2225309-A1 (FR)
Title: Transmission for road vehicle - flywheel between engine and automatic transmission permits use of smaller engine
IPC: B60K6/10
Filed: 1973-04-16
Abstract: The vehicle transmission system particularly for town work, aims to reduce engine size and retains good acceleration by storing energy in a flywheel. This is vertically pivoted so as not to affect steering. The engine drives through an electromagnetic clutch and the outside of a powder coupling. The inner powder coupling member connects the flywheel drive. The drive goes on to another powder coupling and through this to the automatic transmission. Controls enable the flywheel to be engaged and disengaged at will according to the situation involved. For hard acceleration it can double the engine power. For less hard acceleration only the engine is used. A speed detector disconnects the flywheel drive when it attains full speed.

Title: Heat-treating long metallic rods esp. oil-drilling rods - by rotating and moving through heating, quenching and tempering stations
IPC: C21D9/00
Filed: 1974-06-28
Abstract: Plant for the heat treatment of long, round metal parts, comprises >=1 heat treatment device located on the axis (I) of movement of the bars and with supports both upstream and downstream of each device, the supports consisting of numerous rotating rolls on both sides of axis (I) and on shafts parallel to axis (I), at least one of the rolls being driven continuously. The row of supports includes several cradles which can be raised from a lower position, in which the bars being treated are rotated by the rolls, to a higher position where the bars are lifted off the rolls and are moved horizontally by the cradles in their direction of travel. Method is useful for quenching and tempering bars or pipes in carbon- or alloy- steels or non-ferrous metals, esp. drill-rods for oil-drilling rigs. The bars can be rotated without longitudinal movement and then moved longitudinally without rotation, so no distortion occurs in heat-treatment.

Title: Inflatable compartmentalised safety mattress for rescue work - catches people jumping from height and provides flotation
IPC: A62B1/22
Filed: 1974-07-11
Abstract: The mattress is made from plastic or proofed textile material of square, round or other suitable shape. The mattress is in two parts, a lower and an upper, separated by an internal wall; this permits the lower part to be rigidly inflated and act as a support for the upper, which is less inflated to prevent rebounds. The interior is also divided by partitions into compartments to prevent complete deflation, if damaged, and to avoid bulging of sides and tops. Around the outside is a rope handrail and, at each corner, is a handgrip. Inflation is by compressed air bottle or pump. The mattress can be used for water games and as a rescue float.

Title: Thin hollow multicolour moulding, esp. for bathing cap - has sharp colour boundaries obtd. by vent ducts in mould
IPC: B29C43/20
Filed: 1974-10-30
Abstract: Multicoloured, thin hollow articles, such as bathing caps, are mfd. from hot-vulcanised matls. in a multipart mould consisting of a core piece and external shell components. A number of pellets, one for each different colour of matl., are preheated at 30 degrees C and placed in the mould; they are heated to 155-160 degrees C at 200 kg./cm2 until the resultant viscous pools of matl. from all the pellets extend almost up to the junction lines of the colours in the final intended prodt.; the pressure is released and the matl. allowed to continue its flow towards the junction lines under its own elasticity, until the joints are formed, whereupon prevulcanisation, induced by a coumarone cpd. takes place. The temp. of 155-160 degrees C is still maintained, and the pressure of 200 kg./cm2 is re-applied to complete vulcanisation. A clear line of definition is produced at the boundary between different colours.

Title: Rear fork strut for bicycle - is formed by rolling flat plate round core with transverse drilling
IPC: B62K19/38
Filed: 1974-10-28
Abstract: The strut is in the form of a tubular component with two coaxial transverse drillings halfway along it. It has fixed to it a shorter central core (7) with a central transverse drilling. The tube is formed by rolling a flat plate (3) round the core. Initially the plate can have two drillings on its transverse centre line. The core is placed on the plate so that the axis of its drilling is parallel to the line through the centres of the drillings in the plate, and secured to it, after which the plate is rolled round it. The core can have ribs (9) biting into the wall of the strut, and it can be secured in place by spot welding.

Title: Telephone equipment for subscriber charge monitoring - uses 12KHZ signals summed with speech currents to energise the subscriber counter
Inventor: ROUX ROBERT LE
IPC: H04M15/28
Filed: 1974-12-19
Abstract: The subscriber-charge signals from the telephone exchange (2) originate from a 12 kHz oscillator (6) switched by the exchange (5) as a function of the call connections and transmitted as a chain of pulses. The 12 kHz signals are resistively mixed by a summing amplifier with the speech signals from the exchange (22, 23) and transmitted via a hybrid junction (11) to the subscriber. A band-pass filter allows speech frequencies to reach the handset and a high pass filter connects the 12 kHz signals to a detector and a counter. This enables the subscriber to monitor the cost of a call and improves the previous design.

Title: Multiple row disc type sugar beet harvester - has pivotal spring mounted row guide arms
IPC: A01D25/04
Filed: 1975-02-11
Abstract: The attachment has a rigid frame (1) carrying the discs (4) used to lift the crop. These discs are concave and rotate on a fixed vertical support leg. Next to each disc and support, on the innermost side, is a vertical column (5). Hinged (7) to each is an extension leg (6), profiled at the bottom (3) to act as a guide and having a coil or leaf spring (8) on the hinge pin side. This biases each leg towards a vertical position against a stop (9). The average spring force causes the harvester to follow a mean path determined by the spacing and direction of the rows.

Patent FR-2304915-A1 (FR)
Title: Liquid conductivity measurement and control probe - with (PTFE) insulated electrode tips for linear variability
IPC: G01N27/07
Filed: 1975-03-19
Abstract: Probes of variable permeability (electrical) for measuring the resistivity of liquids between two parallel electrodes have electrode tips enclosed in a block of insulating material. Isolation of the electrode tips eliminates end effects and consequent nonlinearity of response with respect to variations in the length of the electrodes in contact with the liquid. The linear signal thus obtained simplifies dependant process control adjustments. The circuit characteristics do not necessarily require an integral amplifier to provide control signals.
