Patent FR-2290534-A1 (FR)
Title: Forming causeway foundation - using armouring mesh of threads and multiple fibre bands
IPC: E01C3/06
Filed: 1974-11-05
Abstract: Foundation for earthworks comprises an embedded net e.g. of synthetic or glass fibres, having spaced, parallel threads (1) and crossing parallel bands (2). The threads (1), which can be of polyester or polypropylene, are drawn or spun as a group of fibres and are stronger than the bands (2) which are individual fibres of the same materials. The threads (1) are oriented to be transverse of the foundation to accommodate tensile stressing. The bands (2) preferably extend longitudinally of the foundation. The bands (2) are relatively flexible, allowing hillocks (3) of earth to form in the mesh openings, thus giving high friction between the net and earth.

Title: Composite coloured plastic components - obtd. by injection moulding - bonding rigid plastic layer to prefabricated parts of flexible plastic material
IPC: B29C45/14
Filed: 1975-02-24
Abstract: Composite coloured plastic components, esp. multi-coloured rear lights for automobiles, are produced by (a) plasticising >=1 prefabricated part of flexible plastic matl. against the surface of one mould half; (b) closing the second mould half against the first mould half; and (c) injecting a rigid plastic material into the mould so that the resulting layer bonds to the plasticised, flexible plastic material. Accurately moulded, composite plastic components are obtd. having a strong bond between the two materials. The flexible material protects the component from breakages or damage through impacts, and the rigid material provides dimensional stability.
Patent FR-2264428-A1 (FR)
IPC: H03K3/45
Filed: 1975-03-07
Abstract: A pulse generator is comprised of an asymmetrical magnet assembly and a Hall sensor operative for generating an electrical signal upon the application of a magnetic field thereto. The Hall sensor and magnet assembly are mounted for relative movement for the generation of a train of electrical signals in response to relative displacement therebetween. The asymmetrical multi-pole magnets in the magnet assembly have a plurality of symmetrically spaced pole pairs with each pole pair including a magnetic pole of predominant polarity occupying a substantially greater area than the pole of opposite polarity. The predominant pole is sufficiently strong to provide a salient magnetic field of essentially single polarity. A magnetizing head also is provided for producing the asymmetrical pole character of the magnet.

Title: Feed device for sprayer - has housing with sheath internally connected to tank keeping fluid at constant level
IPC: F23K5/02
Filed: 1975-06-27
Abstract: The feed device supplies a sprayer operating on the ejector principle, such as an oil-fuel burner. It comprises a closed housing (5), inside which a sheath (14) is mounted, open at the top and sealed to the housing at the bottom. A pipe (8) opening into the sheath leads from a storage tank at atmospheric pressure, while a further pipe (6), opening into the housing, leads to the sprayer. The depression created in the housing draws up liquid from the storage tank into the sheath continuously, replenishing the housing so that the level (10c) inside it only varies within very narrow limits. Consequently, the rate of feed to the sprayer is kept constant.

Title: Deceleration shock damper for vehicle clutch - with reverse torque limiter in parallel with forward drive free wheel
IPC: F16D41/067
Filed: 1975-08-01

Title: Acceleration of solidification and hardening of cement - using mixt. of polymerised alkylbenzenesulphonate and ammonium polyacrylate
IPC: C04B24/22
Filed: 1976-02-09
Abstract: Acceleration of the solidification and hardening of cement is effected using an organometallic prod. such that it has no harmful secondary effects on the cement. Pref. families are polyermised organometallic sulphonates, or their derivs.; and organometallic acrylates,or their derivs. Partic. pref. is a mixt. of 80 wt. % polymerised alkylbenzenesulphonate and 20 wt. % ammonium polyacrylate, the mixt. being added to mixing water at 1-2 pts. wt. per 1000 pts. cement. Such accelerators avoid the disadvantages of previously used mineral salts. They extend the surfaces of contact as well as the electrostatic activity of the surfaces. This accelerates solidification or hardening through a high cohesive force between the particles. Adjustment of the acceleration can be effected by varying percentages and mixtures. The prod. retains water and is a plasticiser.

Title: UHF television tuner production - involves using prototype which is established by empirical adjustment of two-section earth plate for optimum coupling (NL070976)
IPC: H03J3/18
Filed: 1976-03-05
Abstract: A method for the production of HF circuits, is used especially for UHF television tuners. There is an HF resonant circuit connected at two different earth points to an earth foil (43) on a circuit board, and with a coupling circuit also connected to two different points on the earth foil, which is difficult to design theoretically. A model of the HF circuit is first built, and the degree of coupling between the resonant circuit and the coupling circuit is adjusted by making interruptions at different points of the earth foil. When satisfactory coupling is achieved the model is taken as a production prototype. The adjustment may be effected by using two sections to the earthfoil, bridged at several points, and breaking the bridges successively until those remaining provide the necessary degree of coupling.

Title: Swivel plate mounting for opposing press tools - is for installation of tubular rungs in metal ladder (NL 18.12.78)
IPC: B21D39/06
Filed: 1977-06-14
Abstract: The press tool for fitting the rungs (1) in metal ladders (4) includes at least two opposing tool heads (11) mounted on a common base plate. Hydraulic cylinders (13) provide the axial force required to form the two ends of the tubular rung (1) on installation. The form punch (6-9) which expands and then rolls over the outside ends of the rungs, is mounted on a segment plate (10). Thus in cases where the two ladder beams (2) are not parallel, the punch tool on the segment base (10) is self adjusting to the inclination of the ladder beams. A uniformly rolled end of the ladder rung is therefore produced.
