Title: Polymer and process
Inventor: GILLAN J
IPC: C08K7/00
Filed: 1970-12-15
Abstract: 1332469 Porous polyester granules BALM PAINTS Ltd 15 Dec 1970 [22 Dec 1969] 59518/70 Headings C3C and C3P Porous cross-linked polyester granules are made by forming a solution of an unsaturated xylene soluble polyester resin containing free carboxyl groups in an essentially water insoluble polymerizable unsaturated monomer and suspending this solution as discrete globules in an aqueous continuous phase in the presence of from 0À3 to 10À0 equivalents per free carboxy group of a base having a dissociation exponent i.e. -log 10 K b  where K b  is the dissociation constant of the base in water at 25‹ C., less than 8, initiating polymerization to cross-link the polyester resin, recovering the granules and allowing them to dry in air until the liquid has diffused out of them. If desired droplets of an aqueous liquid may be pre-dispersed within the polyester solution before dispersion of this  solution in the continuous phase. The polyester resin is selected by the following test, to a xylene solution of the resin is added with mild agitation 5% by weight of an aqueous solution of ammonia and the mixture examined under an electron microscope to determine if a stable dispersion of droplets has formed and provided the mixture is essentially free of disperse particles greater than 5 microns and remains so for up to 30 minutes the resin is regarded as satisfactory. The unsaturated polyester resin contains an alpha, beta, ethylenically unsaturated acid such as maleic, fumaric, itaconic, citraconic or mesaconic acid. The preferred monomers are styrene, alpha-methyl styrene, divinyl benzene and nucular-substituted vinyl toluene. In addition minor amounts of other polymerizable monomers may be present such as acrylic and methacrylic acid esters, acrylonitrile, vinyl acetate, tetra-allyl ethoxyethane, ethylene glycol dimethacrylate, or triallyl cyanurate. The base may be an inorganic base of which ammonium hydroxide is preferred, or an aliphatic amine of which a long list is given. The polymerization within the globules is initiated by free radical compounds such as an organic peroxide or azo-compound or by exposure to a radiation source such as radioactive cobalt of ultra-violet light. The polyester resin may contain pigments e.g. TiO 2 . The aqueous phase may contain surface active agents, and thickeners such as hydroxyethylcellulose or polyvinyl alcohol. Exemplified polyesters are made from fumaric acid, phthalic anhydride and propylene glycol and maleic anhydride, phthalic anhydride and propylene glycol. The granules are used as matt texturing, flatting and opacifying agents in paint compositions. The granules may also contain pigment particles e.g. TiO 2 , by forming the granules in the presence of the pigment. Examples 7, 8, 10 and 11 relate to paint compositions and example 9 to the preparation of an opaque sheet.

Patent GB-1286969-A (GB)
Title: Patterned coating on a substrate
Inventor: GUTTRIDGE DAVID
IPC: C23C24/02
Filed: 1969-12-24
Abstract: 1286969 Welding by pressure TELCON METALS Ltd 23 Dec 1970 [24 Dec 1969] 62859/69 Heading B3R [Also in Division C7] A method of forming a patterned coating of a conductive or semi-conductive metal on a substrate comprises applying the metal in a finely-divided state to the substrate, applying pressure to effect cold-welding of the metal to the substrate in a selected area or areas corresponding to a desired pattern and removing any excess unbonded coating material. The method is used to apply a band 3 of aluminium to the central portion of a strip 1 of integrated circuit lead frames 2. The strip 1, of nickel-iron or steel, is drawn through a suspension of aluminium powder in alcohol, a thin layer of aluminium being deposited by electrophoresis; the strip is then dried and passed between pressure rolls one or both of which has a raised pattern, the coating finally being sintered in a sintering furnace preferably under a controlled atmosphere. The aluminium coating provides improved conductivity and facilitates the attachment of circuit components. Thus a semiconductor chip having Au or Al lead wires may be soldered or welded to the ends of the radial finger portions. The metal powder may be applied by alternative steps, e.g. merely laid on the strip or painted thereon in a binder.

Title: Bonded polycrystalline diamond body-silicon carbide or silicon nitride substrate composite
IPC: B24D3/08
Filed: 1978-10-12
Abstract: The composite comprises diamond crystals and a substrate of polycrystalline silicon carbide or silicon nitride bonded by silicon carbide and a carbide and/or silicide of a metal which forms a silicide with silicon. A mass of diamond crystals in contact with a mass of eutectiferous silicon-rich alloy and a silicon carbide or silicon nitride ceramic substrate are disposed in a container and placed within a pressure transmitting powder medium. Pressure is applied to the powder medium resulting in substantially isostatic pressure being applied to the container and its contents sufficient to dimensionally stabilize the container and its contents. The resulting shaped substantially isostatic system of powder-enveloped container is hot-pressed whereby fluid eutectiferous silicon-rich alloy is produced and infiltrated through the interstices between the diamond crystals and contacts the contacting face of the substrate sufficiently producing, upon cooling, an adherently bonded integral composite. In a modification, the use of a container is avoided by pressing a cavity in the pressure transmitting powder medium, placing the silicon-rich alloy, diamond crystals and silicon carbide or silicon nitride substrate in the cavity, covering the cavity with further powder medium, then applying isostatic pressure and hot pressing.

Patent GB-2007902-A (GB)
Title: Nuclear Reactors
IPC: G21C3/00
Filed: 1978-12-01
Abstract: A liquid metal cooled fast breeder nuclear reactor has a fuel assembly or core comprising a plurality of closely spaced elongate fuel sub-assemblies upstanding side-by-side from a support structure. The sub-assemblies each comprise a plurality of spaced fuel pins within a tubular wrapper (15) of cross- section generally hexagonal. The corners of the wrapper are replaced by flat sides (15b) or by sides which are inwardly convex (Figure 5, not shown) which have the effect of increasing the resistance of the wrapper to dilation under coolant pressure. Reduced dilation enables the sub-assemblies to be more closely spaced so that vibration is reduced and the fuel inventory of the reactor can be increased even though the number of fuel pins in each sub- assembly is reduced. <IMAGE>

Patent GB-2054155-A (GB)
Title: Suppressing Rotational Sidebands in NMR Spectrum
IPC: G01R33/46
Filed: 1979-07-17
Abstract: A nuclear magnetic resonance line broadened by an inhomogeneous magnetic field from magnet 10,12 can be narrowed by rotating sample 16. This, however, produces rotational side bands having a frequency equal to the frequency of a main signal plus/minus integer multiples of the speed of rotation. The generation of such spurious rotational side bands is avoided by varying the speed of rotation of the sample within a predetermined range of speeds. The lower limit of said range should be high enough to provide for narrowing the nuclear magnetic resonance lines by rotating the sample. The speed variation can be achieved by means of element 22 (similar to a peristaltic pump) across valve 20 in air line 18 which drives turbine rotator 14. <IMAGE>
