Title: Improvements in suspension type heat exchanger and method of heating finely divided solids
IPC: F27B7/20
Filed: 1955-07-11
Abstract: 793,713. Preheating furnace charges. KENNEDY VAN SAUN MFG. & ENG. CORPORATION. July 11, 1955 [July 23, 1954], No. 20038/55. Class 51 (2). [Also in Group XXXVII] In a heat exchange tower 12 for preheating cement raw materials being fed to a rotary furnace 10 in a generally counter-current direction to hot waste gases issuing therefrom, the raw materials from a hopper 14 fall successively through a series of chambers 17, 22 and 26 or 18, 23 and 27, and the waste gases are caused to traverse each chamber in the same direction as the falling materials. From the furnace the gases pass in turn up a central flue 30, down the chambers 26 and 27, up side flues 34 and 35, down chambers 22 and 23, up a central flue 37, down chambers 17 and 18, up flues 39 and 40, and out through openings 41 and 42 into cyclone separators 43 and 44 from which an extractor fan delivers them into a stack running parallel with the tower. If necessary, the hot gases can be diverted at the foot of the tower directly into the stack. The side walls of each chamber are formed with baffles 19 defining a circuitous path for the materials and the waste gases, and the sudden reversal of the waste gases at the foot of each chamber causes the bulk of the raw materials to separate out. Passage of the raw materials downwardly from the hopper 14 is controlled at each stage by rotary pocketed valves 16, 20, 21, 24, 25, 28 and 29 arranged as shown in pairs. Additional rotary valves 47 control the passage of fires from the separators 44 and 43 to points above the valves 20 and 21 respectively, and a further valve 51 discharges any material collecting in the central flue 37. The valves, shown in detail in Fig. 3, each comprise a cylindrical body formed with an axial passage for cooling air, and blade members 59 defining the intervening pockets. Above each valve is disposed a mounting comprising hollow side sections 60 and a grating 61. Driving motors for each set of valves and fans supplying the cooling air are disposed on platforms 55 mounted on the tower, and inspection doors 52 allow of access to the gratings 61 from these platforms. If the rotary valves jam they are automatically reversed by a motor-controlling circuit (see Group XXXVII).

Filed: 1959-06-12
Abstract: 856,223. Spanners. PERSSON, S. H. June 12, 1959, No. 20133 /59. Class 61. A multiple spanner comprises a plurality of hexagon keys of different sizes pivoted individually on a common axis at one or each end of an elongated carrier which is provided with a leaf spring which when a selected key is moved from a collapsed position to a position of use at right angles to the carrier co-operates with means on the key to retain the key in position. As shown the carrier 1 is U-shaped in cross-section and is provided on the base with an upstruck boss 12 which serves to locate and retain a spring plate 11 in position the plate having an inverted U-shaped portion 10 on which the lower keys 7 rest. The plate terminates at each end in spring fingers 13 which act individually on the adjacent keys 7, 8. The pivoted hook-end of each key is curved and formed with a flat 14 which engages with a spring finger 13 when the key is pivoted into a position at right angles to the carrier. Each end wall of the carrier has a sloping top edge 15 which supports the keys when moved into the extended position of use.

Filed: 1970-04-27
Abstract: 1298719 Electrochemical analysis PERKINELMER CORP 27 April 1970 [25 April 1969] 20154/70 Heading G1N The solid connection of a lead-in wire to an ion-selective "semi-conductor" membrane is made by a metal capable of forming an ionic semi-conductor or ion transport compound with the anion of the membrane. The metal may be a powder loading in epoxy resin or a coating on the membrane enabling a standard e.g. copper epoxy bonding to be used. This connection avoids "polarization" due to static handling charges in dry condition which may cause protracted instability. EXAMPLES:- connections with lead or bismuth may be used with fluorides of lead, bismuth, yttrium, scandium or the lanthamide series; lead or silver connections may be used with lead chloride.

[Also in Division C3] In a method of coating a mould for use in producing steel ingots or slabs of copper or nickel or alloys thereof a body of volatilizable substance together with an exothermic product is ignited to burn in the mould and total combustion is prevented by restricting access of oxygen to the interior of the mould and using a controlled amount of an oxidizing agent, so that a " sticky " rather than a " sooty " layer of a material, usually containing carbon, is deposited on the interior mould surface. The volatilizable substance may be a bituminous material, e.g. pitch, or a carbocyclic chemical substance, a mixture of ester gum and formaldehyde resins or a mixture of camphor and naphthalene. The exothermic product may be an aluminothermic composition or a porous material, e.g. matted cellulosic fibre, impregnated with an oxidizing agent, e.g. nitrate or perchlorate. The exothermic product may be in a finely divided form throughout the body of the volatilizable substance which may be packed in a paper bag impregnated with the oxidizing agent. The exothermic product may also be in the form of cup-shaped bodies into which the volatilizable substance is placed or a two-layer slab of exothermic product and volatilizable substance may be used. Suitable compounds for the volatilizable substance include carbocyclic hydrocarbons such as naphthalene, phenanthrene, anthracene, biphenylene, naphthacene, rubrene, pentacene, heptacene, pyrene, perylene and acenaphthene; phenolic compounds such as resorcinol, hydroquinone, alpha- and beta-naphthol, anthraquinone and quinol, esters of carbocyclic acids such as pentaerythritol and glycerol esters of rosins; terpene compounds such as camphor, borneol, pinene or abietic acid; natural or synthetic resins containing carboxylic groups such as phenoformaldehyde, copal, terpene resins; and nitrogenous compounds such as α-naphthylamine and the aminoanthraquinones.

Title: Low Tar-Producing Tobacco Product and Method of Making it.

IPC: A24B15/12
Filed: 1968-05-02
Abstract: 1,171,878. Reconstituted tobacco. KIMBERLY-CLARK CORP. 2 May, 1968, No. 20943/68. Heading A2C. [Also in Division D2] A reconstituted tobacco sheet, which on smoking produces less tar than normal tobacco, comprises a porous paper-like web impregnated with tobacco extract material, the web comprising tobacco fibres whose looseness of bonding is such that the void fraction of the sheet, is substantially uniform throughout the sheet, and is at least 45 per cent. The void fraction is defined as the volume, per unit volume of the sheet, that is occupied by labyrinthine passages and voids therein. The sheet is produced by modifying the normal making process by: reducing the beating of the tobacco fibres; introduction of minor amounts of non-bonding fibrous or particulate matter to the fibre slurry, e.g. unbleached kraft hardwood fibres, cotton linters, or calcium carbonate; addition to the web making stock, or to the wet web, of volatile organic liquids, of which a mixture of acetone and xylene is exemplified, to reduce hydrogen bonding during drying out; or minimising the compaction of the web and bonding of the fibres by means such as using minimal restraint during drying or reducing the wet pressing.
