Title: Improvements in or relating to flooring materials and methods for the manufacture thereof
Inventor: MOSS DENNIS ARTHUR
IPC: D06N3/06
Filed: 1963-04-09
Abstract: A flooring material comprises a substrate of backing material, a cured polymerized vinyl resin bottom layer on one side thereof and a cured polymerized vinyl resin top layer on the opposite side thereof, the bottom layer, which is to be face downwards on the laying of the flooring material, being of greater thickness than the top layer. The flooring material may be made by spreading a layer of vinyl resin paste on one side of the backing material, curing it and repeating the process on the other side of the backing material.  A polymerized vinyl resin wear layer may be provided on the cured top layer, for example by coating the top layer with a vinyl resin paste and curing. The wear layer may be transparent, coloured, mottled or have patterns embossed thereon. The preferred vinyl resin is polyvinyl chloride and the paste may contain plasticisers e.g. nonyl, octyl, butyl, benzyl butyl, and dialphanol phthalates, trixylenyl and tricresyl phosphates, stabilizers e.g. barium-cadmium soap, dibutyl tin dilaurate, dibasic lead carbonate, lead stearate, pigments, fillers e.g. CaCO3, viscosity depressants e.g. hexylene glycol, and solvents e.g. aliphatic mineral spirit.  The backing material may consist of woven or non-woven fabrics or rubber-impregnated paper. Woven fabrics may be prepared from natural or synthetic fibres e.g. viscose, cotton, or hessian.  Non-woven fabrics may be prepared from synthetic or natural fibres e.g. viscose fibres bonded with polyvinyl alcohol, polyvinyl acetate or synthetic rubbers.  The coatings may be formed using conventional techniques e.g. spreading knife, roller coaters, hot melt coaters and extrusion coaters.  A pattern may be printed on the top layer after curing, and a transparent wear layer added thereafter.

Title: Improvements in or relating to arrangements for counting electrical impulses
IPC: H03K23/82
Filed: 1943-08-31
Abstract: 567,863. Electric selective signalling. STANDARD TELEPHONES & CABLES, Ltd., BRAY, F. H., and BROWN, L. R. Aug. 31, 1943, No. 14180. [Class 40 (i)] [Also in Groups XIX, XXXIX and XL] In a system in which electric impulses arc counted by an endless chain of discharge tubes, the tubes are rendered non-conducting in groups instead of one at a time in response to the discharge in the next succeeding tube as described in Specification 566,156, [Group XL]. By this means, very rapid impulses can be counted. The invention can be used for generating one impulse per n cycles of a controlling A.C. for generating switch-stepping impulses in a telephone exchange, for counting forward or reverting impulses in a register controller or similar distant control system, for counting articles or to indicate the frequency of an oscillator by counting the number of cycles in a fixed time. In the system described, each cycle of the chain forming the subject matter of the invention sends an impulse to a chain of the kind described in the above mentioned Specification and each cycle of the latter sends an impulse to a relay chain. The latter may control lamp circuits and the discharge tubes may be visible through numbered apertures so as to indicate the three digits of the number of impulses received. Circuit details. Momentary operation of a primary key PK ionizes tubes V2, V13 and relay A in the respective chains. Thereafter, when start key SK is operated each positive half cycle after amplification in a tube VT1 causes the discharge of a condenser through a mercury vapour tube MT1, and a consequent sudden change in the potential of the lower ends of condensers C4 ... C14 connected to the starting electrodes of the tubes of the units chain followed by a gradual restoration of the initial potential. Since V2 is passing current, V3 is in a condition to respond (owing to the voltage drop in resistance R36) and breaks clown, preparing V4. Owing to the high xesistance R23, V4 is not in a condition to discharge until the impulse that discharged V3 has ceased. In response to the next impulse, V4 breaks down and prepares V5 and so on. V5 also changes the grid potential of a valve VT2 associated with a common part of the discharge circuits of V1 . . . V4 so as to stop the discharge in these tubes. Similarly V9 stops the discharge in V5 ... V8 and V2 stops the discharge in V9 ... V11. The discharge of V11 causes both VI and V2 to discharge in response to the next impulse and the former delivers a pulse to the chain V13 ... V22 which operates as described in the prior Specifications referred to. When V22 discharges, it causes the next impulse to discharge both V12 and V13 and the former energizes a relay IP which gives an impulse to a relay counting chain of known kind in which each relay is operated over a winding of the preceding relay which it unlocks so that the preceding relay holds only until the end of the impulse.

Abstract: 1361489 Removal of sludge from solutions used for treating metals CARRIER DRYSYS Ltd 4 April 1972 [12 May 1971] 14495/71 Headings BID and B2P  Sludge-containing solution, such as zinc phosphate solution which has collected in tank 4 after being sprayed over automobile bodies 1 moving through compartment 3, is withdrawn from tank 4 by pump 9 at a rate in excess of the capacity of a subsequent filter and is passed through pipe 23 to centrifuge 14 which separates some of the soultion from the mixture, this solution being returned from the top of the centrifuge through pipe 26 to tank 4. The concentrated sludge leaving the bottom of the centrifuge flows to a band 17 of filter paper drawn from a reel across trough 19, the rate of flow being controlled to within the capacity of the filter, and the filtered solution is returned through pipe 20 to tank 4. Clear solution flows over weir 12, and is pumped through heater 6 to the spray means 7 in compartment 3. When the thickness of sludge on band 17 is too great to allow liquid to run through the filter as fast as it is being supplied thereto, the liquid level in trough 19 rises and operates a float switch (not shown) which causes the band 17 to run on and expose a fresh section of the band. The band carrying collected sludge moves down chute 21 to skin 22. The lower outlet 15 of centrifuge 15 may comprise an adjustable valve. In one embodiment, sludge-containing solution is pumped to centrifuge 14 at the rate of 110 gallons per minute, and concentrated sludge is delivered to filter-band 17 at 10 gallons per minute. Two or more centrifuges leading either directly, or via a further centrifuge, to one or more filters may be employed. The piping is preferably made of stainless steel.

Abstract: 830,030. Jet-propulsion plant. ARMSTRONG SIDDELEY MOTORS Ltd. May 4, 1955 [May 20, 1954], No. 14797/54. Class 110 (3). [Also in Group XII] A reheat device for a turbo-jet engine comprises a fuel manifold 12 to be supplied with fuel through an altitude-responsive control 13, a flame stabilizer downstream of the manifold, and means for supplying a predetermined additional rate of flow of fuel and oxygen to the interior of the stabilizer at and above a predetermined altitude (say 40,000 ft.), the fixed rate of flow being sufficient for operation of the reheat device at a predetermined maximum operating altitude (say 100,000 ft.) of the engine, the altitude-responsive control 13 being operative to reduce to zero the flow of fuel to the fuel manifold at the predetermined maximum operating altitude. In Fig. 1 the flame stabilizer comprises an annular casing 15 supported by struts 16 of aerofoil cross-section. The casing 15 is flared at its open down-stream end, and fuel and oxygen are supplied to its interior at its closed upstream end by nozzles 18, 19 fed through passages within the struts 16. The axial spacing of the fuel manifold 12 is such that fuel from the manifold is at least partly vaporized by the time it reaches the stable flame zone at the downstream end of the stabilizer casing. The oxygen supply to the nozzle 19 may be in the form of liquid or gaseous oxygen or in the form of hydrogen peroxide. The fuel supply to manifold 12 is controlled by the altituderesponsiye control 13 to decrease progressively with increase in altitude until at maximum altitude all the reheating is effected by the fuel and oxygen supplied to the stabilizer 15; at low altitudes, below 40,000 ft, it is unnecessary to supply fuel and oxygen to the stabilizer 15.

Abstract: 847,878. Recovering titanium from scrap, electrolytically. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 24, 1959 [May 9, 1958], No. 14886/58. Class 41 Titanium is recovered from scrap using a molten electrolyte, and as anode a molten metal on which the titanium scrap floats submerged in the electrolyte, in which the titanium dissolves and is deposited electrolytically on a steel cathode, leaving some impurities floating on the molten metal and some dissolved therein. The molten metal, preferably tin; lead or an alloy molten at or below 800 ‹C., is circulated by a pump and the impurities are removed. The electrolyte consists of sodium chloride or lithium, potassium or strontium chloride or a mixture thereof, in which 5 to 15 % of titanium chloride is dissolved. A small amount of sodium fluoride may be added. In a suitable apparatus, a steel tank 1 is divided by partitions 7, 8 the latter mounted just above the layer of molten metal 2, which lies under the molten electrolyte 3. The titanium scrap is fed into the bath through a pipe 9, and rests on the slowly moving layer of molten metal; the undissolved residues and slimes 24, pass under partition 8 to a chamber 6, where they are removed from the metal surface. Cathodes of steel 10 are housed in bells 12 surrounded by a cooling jacket or fins 16. The apparatus is filled with argon under slight pressure. The cathodes with deposited titanium thereon, may be withdrawn into the bell 12, cooled in argon atmosphere, and replaced with fresh cathodes. In the initial stage, the preliminnary deposit of titanium may contain oxides and other impurities. The cathodes used in this " conditioning " stage are replaced before the main " production " stage, when the cathode in compartment 4 acts as conditioning cathode to the freshly added scrap. A current density of 4 to 40 amps. per sq. inch is used.. The titanium deposit is washed with sulphuric acid, water, and dried at a temperature not exceeding 60 ‹C.
