Patent FR-2023968-A1 (FR)
Title: Linear trans-quinacridone
IPC: C09B48/00
Filed: 1969-11-20
Abstract: Linear trans quinacridone is prepared by heating 2,5-dianilinoterephthalic acid with a carboxylic acid chloride in an inert solvent. This would normally yield the difficulty filterable alpha-form. The beta-form (I) was only previously obtained by carrying out the reaction in the presence of pyridine bases, this process giving poor yield and being relatively uneconomic. If reaction is carried out in presence of an increased conc. of HCl (II) the reaction mixt. (I) is obtained in high purity and good yield. This may be achieved by passing (II) into the reaction mixture and maintaining a slightly raised pressure.
Patent FR-2096880-A1 (FR)
Title: Laser beam machining appts - automatically adjusted using control beam passing through semi-transparent mirrors
IPC: B23K26/04
Filed: 1970-07-09
Abstract: The machine may be automatically adjusted so that the machining point corresponds with the point of concentration of the beam. The laser beam for machining and the control beam are both concentrated by lenses. The control beam is transmitted by a pair of semi-transparent mirrors so that a portion of it falls onto the article. If the article is located at the foucs of the lens transmitting the machining beam, then the two concentration points coincide. The control beam is reflected back and is detected by a sensor after its frequency has been modulated by a vibrating plate. The electric signal is then rectified and its value gives an indication of the gap between the article and the lens focus. The signal may be passed to a servo-motor which automatically adjusts the position of the machining head.

Patent FR-2115456-A1 (FR)
IPC: B29C65/08
Filed: 1971-11-26
Abstract: 1322849 Seaming non-metallic sheet material BRANSON INSTRUMENTS Inc 23 Nov 1971 [27 Nov 1970] 54348/71 Heading B5K In a method of ultrasonically seaming a workpiece fed continuously past a resonator 22, the velocity at which the resonator 22 resonates is adjusted in dependence upon the rate of which the workpiece is fed past the resonator. The velocity of the resonator is the peak displacement amplitude at the output surface of the resonator per unit of time in a direction toward the workpiece. The resonator 22 is vibrated by a magnetostrictive or piezoelectric transducer supplied with high frequency electrical energy and its work surface is mounted to form, with a rotatable anvil wheel 24, a nip through which the material to be bonded, e.g. woven fabric made wholly or partially of thermoplastic fibres, is passed. The work surface of the resonator is disposed at an antinodal region. An electrical power supply 26 is mounted to the work-table 12 and supplies h.f. energy to the transducer. A foot control 28 is connected by a rod 30 to a control box 32 which has a dual function i.e. controlling the feed rate of the material and controlling the velocity of the resonator 22 in a predetermined and co-ordinated manner such that the velocity of the resonator increases linearly with increasing feed rate but at a rate which is less than the increase of the feed rate. As shown in Fig. 2, the wheel 24 is mounted on a shaft 36 extending from a gear reducer 38 driven by an electric motor 40 and is exchangeable for a wheel having a different raised pattern thereon, for examples see Fig. 3. When a knee operable control 34 is moved to the right against the action of a spring 44, a switch 46 is actuated to actuate a solenoid valve (not shown) to cause a piston working in a cylinder to lift the resonator 22 by a predetermined amount to facilitate insertion and removal of workpieces. Electrical circuits (n.s.) for the control of the machine are described.

Energy is stored by virtue of the air being compressed and when required the air is allowed to drive a dynamo or alternator. The storage tank is provided with a large piston normally held at the head of the tank by a cable and pulley system. If the air pressure falls below a usable level, the piston is released and makes up for the lack of such pressure.

Title: Resin impregnation of net covers to stabilise an/or seal soil - to inhibit soil erosion or seal hydrocarbon tank farm bunds.
IPC: E02D17/20
Filed: 1974-04-12
Abstract: Stabilisation of landscapes susceptible to erosion or sealing of earth surfaces is provided by covering the surface with a mesh or net made of rot-proof material and then spraying the net with an emulsion of a resin. Method is for stabilising loose soil to establish vegetation or to seal bund banks surrounding hydrocarbon storage vessels. Compared with conventional bitumastic dressings the lighter coloured resins absorb less solar heat, do not directly support nor are consumed by vegetation. They are permeable to water vapour, e.g. rising from the soil. Dendritic penetration of soil by the emulsion anchors the net firmly. The net provides lateral cohesion. Pref. an aq. emulsion of polyester or epoxy resin is used, specification bisphenol/epichlorohydrin incorporating an amine or a polyamide amine hardener, or a polyester of mixed, partially esterified phthalic and maleic acids incorporating benzoyl peroxide and dimethylaniline.

Title: Imitation timber grained surface - produced using fluid parting agent and viscous two-component resin to give accurate reproduction
IPC: B44C3/04
Filed: 1974-04-18
Abstract: A high pressure laminate having a three-dimensional surface structure esp. as a relief imitation of wood grain, is prepd. by applying a liq. or pasty parting agent (instead of the more conventional preformed parting sheet) and then applying a matl. which is resistant to the effects of the pressure and/or heat utilised. The relief pattern formed in the surface of the latter matl. may be used as either a negative or a positive representation of the structure required. Pref., the matl. applied immediately after the parting agent coating is a low-viscosity, cross-linking plastics sufficiently liq. to penetrate into the depressions of the surface and form an accurate model. Extremely accurate and long lasting representations are obtd. by a relatively inexpensive process. Pref., parting agent is a wax and the cross-linking plastics an epoxy resin.

Title: Electric fuse with ceramics support base - has fuse wire connected between two pins sealed in epoxy resin
IPC: H01H69/02
Filed: 1974-07-26
Abstract: The fuse has an insulating material support base (2) made of ceramics which has two recesses and holes (4). The bottom of each recess is covered with a layer of epoxy resin (6) which seals a pin (5) fitted in the hole (4). The fuse also has a window (7) made of a material which changes colour due to the increase in temperature of the fusible wire (8). The recesses are filled with silicon oxide to absorb the internal pressure due to the fusion of the wire (8). The silicon oxide (9) is covered by a layer of plaster (10). The middle part of the fuse has the fusible wire (8) and is sealed with a cardboard cover (11).

Title: Rotating milking shed for dairy cattle - has circular attendants' area surrounded by animal stalls enclosed by loop-shaped access and exit corridor
IPC: A01K1/12
Filed: 1974-10-18
Abstract: The grille containing e.g. eight, cattle-stalls is situated around an attendants' area which cannot be reached by the cows. Each stall contains a feeding-trough to which a small partition is attached, preventing the cows from entering the adjoining stall. The radial width of the stall area is less than the minimum length of the animals, so that the animals stand at an angle to the surrounding barrier. The loop-shaped access and exit corridor is approached by a gate allowing a certain number of cows to enter. The cows follow a barrier fixed to the surrounding-barrier and which rotates in a clockwise direction. The front cow of the group admitted into the unit enters its stall through a raised part of the barrier and leaves it through an adjacent raised archway. The cows then leave through the exit corridor. Sliding doors are attached to the barrier. Two feeler rods touched by the cows in the entrance automatically open the doors, and enables a count to be made o f the number of cows.
