Filed: 1968-08-12
Abstract: 1,182,553. Gauging shape or tensions in rolled strip. J.W. TURLEY. Aug. 12, 1968, No. 38437/68. Headings G1M and G1S. Cold rolled steel strip is carried over rubber or rubber faced freely running rollers 1, 5, 9, 16, 17, 18, 19 arranged in line across the width of the strip and supported by a beam 3 and bearing pedestals 2. If the strip is being produced misshapen then the tension at various transverse portions of the strip will vary and cause the rollers at those points to run at slightly different speeds from their neighbours. The rollers are so geared together inside by differentials 12, 14 and by a reversing gear 15 that these differences of speed add up or subtract to slightly rotate a shaft 4 one way or the other which movement is used to either mechanically or electrically indicate whether it is the edges or the centre of the strip which is at over-tension and thus requiring correction.

Abstract: 1,163,588. Automatic alarm systems. J. S. HOYLE. 25 Aug., 1967 [30 Aug., 1966], No. 38622/66. Heading G4N. In an alarm, e.g. fire or burglar, system which includes an alarm circuit and a sounder circuit for producing an audible signal, at E, in response to an abnormal condition, at A, in the alarm circuit, a fault warning circuit provides an indication of a fault in the sounder circuit. The fault warning circuit is independently powered by battery F and includes audible and visible indicators H, J, selectively incorporated into the circuit by switch K. The fault warning circuit is normally broken by contacts G<SP>1</SP> of relay G which is normally energized by the current flowing in the sounder circuit but which current is insufficient to operate the sounder E, e.g. a siren or a hooter. A fault in the sounder circuit, such as a severed lead or failure or shortcircuiting of the mains supply, de-energizes relay G to close contacts G<SP>1</SP> and operate indicator J or H. The alarm circuit may be of the normally closed or open type. In the closed type shown, breaking of the alarm circuit at devices A deenergizes relay C to close contacts C<SP>1</SP> and operate sounder E. Devices A may be fire-alarm push-buttons or heat or smoke detectors.

Title: Improvements in or relating to evaporators
Inventor: JANOVTCHIK VIACHESLAV JANSEN
IPC: B01D1/12
Filed: 1957-12-23
Abstract: <PICT:0845733/III/1> Liquid mixtures e.g. tomato juice, are concentrated by evaporation in an apparatus A (Fig. 1) comprising narrow bore upright tubes 2 down which the liquid mixture is forced at such a rate that they are completely filled, heat being supplied by gases, e.g. steam, or hot liquid, via inlet 18 and outlet 19 to the interior of a shell 1 containing the tubes 2, the heat causing the liquid mixture to boil in the tubes and liberate vapour which is separated from the liquid mixture after leaving the tubes. Concentrated liquid mixture falls through an opening 10 to be recirculated together with fresh liquid mixture through pipe 13 by a pump 12 to the top of the tubes 2, thus forming a closed circuit, or to be discharged through a pipe 22, whilst vapour passes upwardly through opening 9 of a separating vessel consisting of the lower part of a chamber 7, to vacuum producing equipment such as a water-cooled condenser 33.  Fresh liquid mixture is supplied to the closed circuit through a pipe 14.  When the apparatus is used in conjunction with a preliminary evaporator, e.g. of the inclined shell type B as shown, the pipe 14 originates from the shell 40 of the preliminary evaporator. The liquid level in the lower part of chamber 7 is controlled by a float device 15 to give the necessary head to the pump 12.  The preliminary evaporator comprises tubes 41 within its shell 40 which are fed with fresh liquid mixture by a feed pipe 60 which enters a lower chamber 45 of the shell 40.  Vapour passing through opening 9 and pipe 31 (valve 63 closed) condenses on the tubes 41 causing liquid mixture therein to boil, and concentrated liquid mixture and vapour to pass via pipe 50 into a separating vessel consisting of the upper part of chamber 7, upper and lower parts being separated by a partition 8.  Vapour from this upper part passes by pipe 57 to condenser 33 while the liquid passes down pipe 52 into the bottom of the inclined shell 40, thus forming a second closed circuit.  The flow of fresh liquid mixture through pipe 60 is controlled by a valve 61 dependent on the level of liquid in the upper part of the chamber 7.  In the Provisional Specification the separating vessels are not situated one above the other but are spaced apart laterally.ALSO:Tomato juice is concentrated by evaporation in an apparatus comprising narrow bore upright tubes down which the juice is forced by a pump at such a rate that they are completely filled, heat being supplied by gases e.g. steam or hot liquid to the interior of a shell containing the tubes, the heat causing the juice to boil in the tubes and liberate vapur which is separated from the juice after the latter has left the tubes, the concentrated juice being either recirculated for further treatment or discharged (for apparatus see Group III).

Title: Improvements relating to the application of polymeric surface coatings to metal articles by electrodeposition
Inventor: GINGER CHRISTOPHER JOHN
IPC: C25D13/22
Filed: 1964-11-20
Abstract: <PICT:1118783/C6-C7/1> In electro-depositing a coating on a metal article which serves as an electrode and is immersed in an aqueous solution or dispersion containing a polymeric substance, at least one metallic non-deposition electrode is used which is surrounded by carbon contained within a nonconducting sheath, or by cellulose or by asbestos. The surrounding material prevents acid or base generated at the non-deposition electrode from diffusing into the solution. For example, base is generated from a solution containing a resin having carboxyl groups neutralized by a base such as ammonia, an amine or alkali metal hydroxide to make it water soluble.  The carbon may be granular.  The cellulose may be in the form of granules, fibres, paper, sponge or fabric and may be contained in a sheath of fabric or nylon.  The asbestos may be in the form of fibres, paper, fabric or ribbon.  The electrode may be tubular with holes therethrough along its length to allow gas, e.g. H2, produced during the electro-deposition to escape or may be a flexible helical spring, e.g. of Cu, copper-plated steel or Zn-plated steel.  The Fig. shows a Zn-plated steel helical spring electrode 1 sheathed with cellulose paper tissues 2 enclosed in a sheath 3 made from cotton filter cloth. The examples are of applying paint from an aqueous solution of an epoxy resin-based paint and refer to painting steel, painting a petrol tank and to stoving painted articles.
