Patent GB-2006732-A (GB)
Title: Silicon bonded polycrystalline diamond body
IPC: B01J3/06
Filed: 1978-10-05
Abstract: The body comprises a mass of diamond crystals bonded by silicon carbide and elemental silicon. A cavity of predetermined size is formed in a pressure transmitting power medium, a mass of diamond crystals in contact with a mass of elemental silicon are disposed within the cavity and additional pressure transmitting powder is placed over the cavity and its contents producing a powder- enveloped cavity. Pressure is applied to the powder medium resulting in substantially isostatic pressure being applied to the cavity therein and its contents sufficient to dimensionally stabilize the cavity and its contents. The resulting shaped substantially isostatic system of powder-enveloped diamond and silicon is hot-pressed to liquefy and infiltrate the silicon through the interstices between the diamond crystals producing, upon cooling, an adherently bonded integral body.
Patent GB-2008619-A (GB)
Title: Hot Dip Metal Coating One Face of a Metal Sheet
IPC: C23C2/00
Filed: 1978-10-25
Abstract: Metal sheets hot dip coated on one surface only with a layer of a different metal, for example sheets of galvanized steel, are produced by applying a temporary sealing material along the edges of two superposed sheets prior to hot dippings. The sealing material is plastic at the temperature of dipping and so ensures a perfect seal preventing ingress of liquid but permitting minor movements of the sheets under thermal stress and strain without buckling, but which permits an easy separation of the coated sheets afterwards. The sealing material may be a glass, enamel, slag or an alloy.
Patent GB-2010973-A (GB)
Title: Steam Power Station with Fluidized Bed Furnace
IPC: F01K23/06
Filed: 1978-12-22
Abstract: In a process and an installation for operating a coal-fired steam power station, the steam generator is heated by means of a fluidized bed furnace. The furnace of the steam generator (1) is brought under pressure, preferably of about 8 bars, by means of a booster group consisting of a gas turbine (12) and compressor (13). The combustion air at the same time serves as the carrier medium for the fluidized bed. The latter is cooled by running the pipes of the vaporiser (21) through the furnace. The combustion gases are subsequently utilised, within the steam generator, to superheat the steam which is generated and to preheat the feedwater, releasing their remaining energy in the gas turbine of the booster group. <IMAGE>

Title: Device for removing lead particles from the exhaust gases of an internal combustion engine
IPC: F01N13/02
Filed: 1978-12-29
Abstract: Lead particles are removed from the exhaust gases of an internal combustion engine by deflecting the gases radially through holes (11) in the inlet pipe (10) to impinge on a wire mesh or expanded metal packing in a first annular chamber (12) for absorption of lead particles, the gases then passing through a chamber (8) in which a helical vortex flow is imparted to the gases by baffles (19-21), the gases then entering a convergent duct (24), backed by a further porous packing 26, where centrifugal separation of further lead particles takes place. The particles pass through slots 25 into packing 26 while a reversal of the gas flow direction occurs at the narrow end of duct 24, followed by axial straightening of the gas flow by radial partitions 28 before discharge of the gases through apertures 32 into an axial outlet pipe (18). The device also acts as a silencer. <IMAGE>

Patent GB-2029629-A (GB)
Title: Ribbon cable
IPC: H01B7/08
Filed: 1979-08-14
Abstract: In multi-core electric cable in which the cores extend in side-by-side spaced and parallel relationship, instead of producing the cable with the cores continuously interconnected by surrounding insulation so that when cut into lengths the insulation has to be pulled or cut apart in order to separate the cores for connecting, the cable is made at the outset with regions 35 at intervals along its length where the cores have never been interconnected. Methods of manufacturing the cable include those in which each core has an individual insulating sheath 34 interconnected to form the multi-core cable by the bonding of the sheaths together or to backing strip material or to both. In application to multi-core cables made from bare conductors sandwiched between strips of insulating material separation of the cores at intervals is achieved either by omitting at intervals the bonding of the insulating material or by omitting the insulating material at intervals or by a combination of both. Apparatus for, and methods of, so manufacturing flat multi-core electric cable are described. <IMAGE>

Title: Reducing disturbances due to colour crosstalk in a PAL television signal
IPC: H04N11/16
Filed: 1979-11-01
Abstract: A method is proposed for the reduction of disturbances due to colour crosstalk in a PAL colour television signal. For this purpose, at the PAL coder those components of the luminance signal are suppressed which lie in the direction of the U modulation axis of a colour carrier signal modulated in accordance with the PAL standard. In the PAL coder shown, the suppression is performed by demodulating the luminance signal Y in the direction of the U modulation axis in a demodulator 2, effectively subtracting the demodulated signal from the video frequency colour difference signal U in an adder 3, low pass filtering the combined signal at 4, modulating the combined signal onto the colour carrier in a modulator 5, and adding the resultant colour carrier frequency signal to the original luminance signal in the adder 8. <IMAGE>

Filed: 1980-01-09
Abstract: Floating apparatus like a ship or pontoon, a floating factory or the like, comprises a deck 2 having a working deck 3, supported by a hydraulic system 4 with a system of communicating vessels 5. During movements of the apparatus 1 caused by the wash of waves, the working deck 3 is automatically returned to the horizontal position 1. The working deck 3 is centrally anchored at 6 to the apparatus 1 for universal pivoting motion. The working deck 3 is attached to a number of pistons 7 connected to a closed container 8 of the hydraulic system 4. The apparatus 1 is provided with a stop 14 co-operating with the edge of the working deck 3 and limiting a further movement of the working deck 3 with respect to the apparatus 1 just before the maximum stroke of the pistons 7 is reached. In this manner, the workability range of the apparatus is greatly increased because the supported deck portion is kept in a substantially horizontal position by the hydraulic system in spite of the movement of the apparatus caused by the wash of waves. <IMAGE>

Patent GB-2054839-A (GB)
Title: Determining electrophoretic mobility of cells
IPC: G01P5/00
Filed: 1980-06-05
Abstract: The electrophoretic mobility of cells in a solution in an electrophoretic chamber is measured by applying an electric potential to the solution and using a linescan camera to form an image frame by line scanning the cell in a direction perpendicular to the cell movement. Two such image frames are correlated to determine cell mobility in the interval between the two frames. Each line scanned is processed to indicate detected cells and a digital number obtained. A frame is thus represented by a series of numbers which may be correlated. Alternatively and more simply each line is scanned and the presence of any detected cell represented by a logic ONE so that an image frame is represented by a series of logic ONES and ZEROS for correlation with a later series. Integration of successive mobility measurements improves the observed results. A tag inserter provides a visible mark on a television screen to indicate cells that are detected.
