Patent GB-754012-A (GB)
Abstract: 754,012. Measuring extension of objects using radio-active markers. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. April 2, 1954 [May 22, 1953], No. 9806/54. Drawings to Specification. Class 40 (3). A method of measuring variations in the distance between points in an extensible object in an opaque enclosure in which marking indexes of a solid radio-active substance are fixed to the object at the points comprises locating the points outside the enclosure at which the radiation from the indexes is strongest by traversing a radiation detector, located in a block of material impervious to the radiation with a window facing the enclosure, along the enclosure. The indexes may be narrow along the line joining the points and long in a direction at right angles thereto, in which case the window in the block is correspondingly shaped and the detector is traversed in a direction perpendicular to the long dimension. The indexes may be pieces of pure metal (e.g. gold) or alloy wire, a constituent of which has been partially transmuted into a radio-active isotope emitting gamma radiation, the half life of which is about 3 days. The detector may be a Geiger counter operating a pulse counting or integrating device connected to a galvanometer which thus gives an indication of the intensity of radiation reaching the counter through the window. An embodiment is described for measuring the stretching of the core of an armoured cable under tension, in which the indexes are spaced at intervals which are measured before and during the application of tension. In a further embodiment for measuring the displacement between individual conductors in a multi-core cable indexes are provided on each of the conductors.

IPC: C12N5/10
Filed: 1978-06-13
Abstract: Continuous cell lines of genetically stable fused cell hybrids capable of producing large amounts of monoclonal antibodies against specific viruses and their antigenic determinants have been developed. The cell lines are fused cell hybrids between viral antibody producing cells and myeloma cells. Fused cell hybrids between influenza virus-primed mouse spleen cells and mouse myeloma cells can be maintained indefinitely in culture and continue to produce large amounts of anti-influenza antibody.

Title: Nickel-based alloy for nuclear power station components
IPC: C22C1/04
Filed: 1978-09-27
Abstract: The alloy consists by weight, of 1.4 to 2.5% of carbon, 0 to 2% of silicon, 25 to 33% of chromium and 6 to 15% of molybdenum, the balance consisting of nickel and unavoidable impurities, the total amount of cobalt, tungsten and boron in the unavoidable impurities being preferably less than 0.2%, based on the weight of the alloy. The alloy is suitable for components such as stopcocks, valves etc. in nuclear power stations. The alloy has comparable mechanical properties to the cobalt-based alloys conventional for such purposes, but is less susceptible to activation by fission or fusion products.

Patent GB-2006643-A (GB)
Title: Membrane separation and purification of compounds
IPC: B01D69/12
Filed: 1978-10-18
Abstract: A permeable anisotropic synthetic membrane useful in membrane separation processes, for example ultrafiltration, dialysis, electrodialysis, reverse osmosis, gas permeation and gas diffusion, comprises a multi-layered structure with each layer serving as a molecular screen having a precise molecular weight cut-off and wherein between each layer there are rows of alveolae with adjacent alveolae in adjacent rows being connected by means of channels of molecular dimensions. For any type of polymeric starting material it is possible to obtain membranes of a predetermined molecular weight cut- off. The membranes provide a multi- layered action which enables any defect in separation by one layer being corrected by the following layer and so requires a less strict quality control, reducing the cost of manufacture when compared with membranes of the prior art.

Patent GB-2019498-A (GB)
Title: Valves for Pressurised Dispensers
IPC: B65D83/14
Filed: 1979-04-09
Abstract: To form a "vapour tap" in the wall of the shell of a valve for a pressurised dispenser such as an aerosol can, the outer surface of the upper end of the open-topped cylindrical shell is offset radially outwards, possibly by simply thickening it to form a rim 14, and an upwardly extending notch 15 formed in the outer surface of this rim and downwardly extending notch 16 in its inner surface cooperate and overlap to define an orifice. There may be several such pairs of such overlapping notches, the outer one being circumferentially wider than the inner one. This formation of the vapour tap orifice by overlapping notches allows the shell to be moulded easily in a simple mould, yet leaves an unbroken upper annular surface 13 of the rim, for engaging the usual gasket. <IMAGE>

In an alternative construction the free space is formed by a recess. <IMAGE>
Patent GB-2058110-A (GB)
Title: Aqueous correction fluid and method for making same
IPC: C09D133/08
Filed: 1980-07-14
Abstract: Novel aqueous correction fluids comprise a stable emulsion of a water- dispersed, water-insoluble acrylic resin as the binder for the masking pigment. The compositions form smooth, receptive, highly opaque, non-brittle masking coatings and have an acceptable drying time due to the fact that the water content is as low as 25 to 50% of the total weight of the composition. The acrylic binder constitutes more than 10% by weight of the correction fluid and has such a high pigment binding power that it provides, on drying, pigment- air interfaces (without loss of film integrity) which, due to the large differences in refractive index between air and pigment, produce a much more opaque coating than is possible with other resin binder systems. As a result, up to half of the masking pigment content can be replaced by less expensive fillers while still providing acceptable opacity.
Patent GB-2082027-A (GB)
Title: Surge protection
IPC: H05K9/00
Filed: 1980-07-29
Abstract: To provide surge suppression for lines connected to telecommunication apparatus, a number of such lines are terminated on the contacts (1, 2) of a printed circuit board type connector (3). Into this connector there is fitted a metal strip (4) having on each face an insulating coating which breaks down when a preset voltage is applied across it. The connector contacts bear on this strip, so that if a surge greater than that preset voltage occurs on a line wire, the coating between that line wire's contact and the metal strip breaks down. The metal strip is grounded, e.g. by end contacts (5), so that when such a breakdown occurs the surge is dissipated. <IMAGE>

Title: Validating coins
IPC: G07D11/00
Filed: 1980-12-03
Abstract: A coin validating arrangement for a coin operated machine, comprising a coin chute (5) having an upstream coil (8) for sensing a true coin and producing a Q signal output only when a true coin is properly inserted, an obturator (11) generally downstream of the true coin sensing coil, a coin acceptance coil (21) generally downstream of the obturator, and a validating circuit (41) which enables the coin acceptance coil to produce an A signal output which in turn generates an accept signal which activates the machine only when no Q signal output is being produced. In a preferred arrangement, an intermediate or zoning coil (18) produces a Z signal output as it watches the coin through the obturator from the Q coil to the A coil, and production of the accept signal is also dependent on the Z signal. <IMAGE>
