Title: Heat pipe device for vapourizing liquid fuel
IPC: F02B1/04
Filed: 1974-01-23
Abstract: 1497538 Vaporizing liquid fuel using heat pipe SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 21 Jan 1975 [23 Jan 1974] 03171/74 Heading F4U [Also in Division F1] A heat pipe for vaporizing liquid fuel prior to its introduction to an I.C. engine or gas turbine combustion chamber contains a heat transfer fluid and a non-condensable gas and comprises a heat receiving zone 2, in which the liquid heat transfer fluid can be evaporated by heat from the engine or turbine exhaust system; a heat discharging zone 5 in which the vaporized heat transfer fluid can be cooled and condensed to a liquid which returns direct to the heat receiving zone 2 and a heat transfer liquid storage zone 3 in which condensed heat transfer fluid can be stored without being returned directly to the heat receiving zone 2. Additional cooling means 9 may be provided. The heat transfer fluid may be 2-octanol, decane, tetralin or a mixture of water and glycol or water and methanol and/or ethanol. The non-condensable gas is preferably air, nitrogen, helium, argon, neon or krypton. If the rate of supply of heat in zone 2 increases while the requirement for heat in zone 5 remains substantially constant, more of the liquid in zone 2 evaporates (reducing the area of the heat transfer surface, so keeping the rate of heat transport between these zones constant) and condenses in zone 3. If the requirement for heat in zone 5 then increases, the increased rate of condensation in this zone causes a pressure drop so that the non-condensable gas in zone 3 forces some of the heat transfer liquid to pass therefrom to zone 2. In Fig. III (not shown) and Fig. II the zone 3 communicates with the rest of the heat pipe by way of a capillary tube 8, cooling means being provided for zone 3 and the capillary tube. In Fig. III, a second heat transfer liquid storage zone (13) provided with cooling 14 is included.

Abstract: 1,163,340. Rotary heat exchanger. HITACHI Ltd. 24 Jan., 1967 [26 Jan., 1966], No. 3492/67. Heading F4S. [Also in Division F1] In a heat exchanger comprising a stationary spiral fluid flow pipe 16 disposed within a rotary hollow horizontal shaft 9, heat exchange is effected between air flowing over the outer surface of the shaft 9 and a liquid or gaseous fluid 15 flowing through the pipe 16 by means of a heat transfer liquid 20, e.g. water or turbine oil which is sealingly contained by rings 17 (see Fig. 5) within the shaft 9 up to a level 19. On rotation the liquid 20 is forced centrifugally outwards such that the pipe 16 is completely immersed in a layer of liquid. The shaft 9 has a plurality of equally spaced vertical discs 10 joined to its outer surface. A casing 11 partly surrounds the discs 10 so that on rotation of the shaft 9 air is forcedly directed over the outer surface of the shaft from a direction 12, towards a direction 13. In a modification, the pipe 16 may be bent in a zig-zag or other complex shape (Figs. 6, 7).

Title: Improvements in or relating to fluid level detecting devices
Inventor: NAYLOR EDWARD LEONARD
IPC: G01F23/26
Filed: 1967-01-24
Abstract: 1,213,128. Monitoring fluid level electrically.  C.I.A. ELLIS. Jan. 10, 1968 [Jan. 24, 1967], No.3514/67. Heading G1H. The capacitance values of first and second pairs of electrodes 10, 12 and 10, 14, Fig.3, are equal when a fluid level 18 (or the interface level between a pair of fluids) is located either below or above the position of the electrodes, but become unequal when the level registers with either one of the pairs or the space between. The capacitors C1, C2, Fig. 2, formed by the electrodes are connected in a bridge circuit to determine the feedback between the input and output of an amplifier A by way of a transformer L, Lc, the arrangement being such feedback occures to produce oscillation in the amplifier loop only when the bridge circuit is unbalanced. Thus, the production of oscillation indicates that the liquid or interface level occurs within the predetermined region of container 16, Fig. 3, occupied by the electrodes. A detecting and amplifying circuit may respond to the oscillations to actuate a visual or aural alarm. The electrodes may be mounted inside tube 16, and at least one may be coated with an insulating material which has no chemical reaction with the fluid in the tube. Where the tube is made of conductive material it may form electrode 10. Balancing capacitors may be connected across each of capacitors C1 and C2. In an alternative circuit arrangement, Fig. 1 (not shown), the two capacitors form the feedback connection from a phase-splitter at the output of the amplifier to the input. The term "fluid" is intended to embrace dry powders, sherries and suspensions as well as liquids.

Abstract: 1,207,654. Reducing the crimp intensity of conjugate acrylic fibres. E.I. DU PONT DE NEMOURS & CO. 22 Jan., 1969 [24 Jan., 1968], No. 3704/69. Heading B5B. The "crimp index" of a helically crimped bicomponent conjugate continuous filament in which each component is an acrylic polymer is reduced by heating the filament, while it is moist, at a temperature of 95‹ to 105‹ C. for a time of 0À5 to 2À5 seconds while maintaining it under an elongating stress of 2 to 20 mg./den., with the proviso that the product of the time and the elongating stress is 2 to 20 mg.sec./ denier. "Crimp Index" is defined as being calculated in accordance with the formula in which L, represents the length of a single fibre of about 3-6 denier under a tension of 5 mg. and L e  is the length of the fibre under a tension of 150 mg. which serves to remove all the crimp without extending the fibre. The term "acrylic polymer" includes both polyacrylonitrile and copolymers of acrylonitrile and one or more monoethylenically unsaturated monomers copolymerizable with acrylonitrile, the percentage by weight of acrylonitrile in the copolymer being at least 88%. The filament may be heated by contacting it with steam or with one or more heated rollers. It may be dry before it is contacted with steam and the steam may be at a temperature of 95‹ to 105‹ C. The filament may have been dyed and may be still moist from the dyeing process before being heated by contacting it with one or more heated rollers. Each of the components of the bicomponent filament may be composed of one or more polymers of acrylonitrile, each of which polymer is a homopolymer of acrylonitrile or a copolymer of acrylonitrile and up to 12% by weight of at least one other monomer which is non-ionizing in neutral media or contains sulphonate groups; each component has no more than 90 meq./kg of combined anionic function; the content of said other copolymerized monomer in one of the components is at least 1% by weight, based on the weight of the filament, greater than the content (if any) of said other copolymerized monomer in the other component; and the ratio by weight of one component to the other component is from 75: 25 to 25: 75 in the cross-section of the filament.

Filed: 1964-01-30
Abstract: Aqueous emulsions of polymers which are non-film forming at room temperature are prepared by the emulsion polymerization of a monomer mixture consisting of, by weight, 0.5-2% of an a ,b -olefinically unsaturated aliphatic carboxylic acid, 33-85% of methyl methacrylate and the balance vinyl acetate; the monomer mixture may optionally contain up to 25% by weight of a C1 to C10-alkyl ester of acrylic acid.  The acid monomer may be methacrylic acid, crotonic acid, itaconic acid, and, preferably, acrylic acid.  The emulsifier may be anionic, nonionic or cationic or mixtures of these, e.g. fatty alcohol sulphates, alkylaryl sulphonates, alkyl sulphosuccinates, alkyl phenoxy - polyethoxy ethanols, ethoxylated methylene-bis-phenols, ethoxylated fatty acids, and ethylene oxide-propylene oxide block polymers.  As polymerization catalyst there may be used inorganic persulphates, e.g. potassium persulphate, hydrogen peroxide, perborates and Redox systems such as hydrogen peroxide-ferric chloride, potassium persulphate-sodium metabisulphite, and t.-butyl hydro-peroxide-sodium formaldehyde sulphoxylate. The monomer mixture is added gradually to the polymerization reaction.  The emulsions are useful as stiffening agents in textile finishing and may also be used to improve certain properties of paper products. The emulsion polymers, when pigmented, may be employed in floor tiles, panels, moulding powders, paints and floor chips.ALSO:The sizing, rigidity and strength of paper products are improved by the use as wet-end additives of aqueous polymer emulsions which are non-film forming at room temperature.  The polymers are derived from a monomer mixture consisting of, by weight, 0.5-2% of an a , b -olefinically unsaturated aliphatic carboxylic acid (e.g. acrylic, methacrylic, crotonic or itaconic acid), 33-85% of methyl methacrylate and the balance vinyl acetate; up to 25% of a C1 to C10-alkyl ester of acrylic acid may also be included in the monomer mixture.
