Title: Heating system utilising catalytic combustion
IPC: B64D10/00
Filed: 1957-05-03
Abstract: 864,064. Combustion apparatus. WEISS, G. May 3, 1957 [Oct. 1, 1956], No. 14179/57. Class 51 (1). In a heating system utilizing catalytic combustion and comprising a longitudinal array of spaced catalytic elements 93, 94, Fig. 5, each of said elements is formed of a sheet-like base 79, Fig. 3, to which is applied a catalytic layer 80. Air-fuel mixture is supplied substantially simultaneously to all the catalytic layers through the tubular base members 79 and spacing tubes 73 and through discrete openings 81 through the said members. The air-fuel mixture is directed along the catalytic layers to exhaust openings 82 in cover tubes 78 for the elements to atmosphere or to an outer tube 84. The main air-fuel stream passing through the base members 79 transfers a part of the heat generated at one element to the succeeding element to ensure the continuous operation of all the elements. A pre-heating device may be provided before the first element and a similar device may be provided after the last element to completely burn out the exhaust gases and reduce odour. The catalytic layer of the elements may be in the form of a separate sleeve radially spaced with respect to the base tube member. Pressure operated non-return valves may be provided for each heater element to isolate the same during non-operation thereof. In modified arrangements the flow of air-fuel mixture may be from an outer tube inwardly to a central tubular exhaust passage and the supply to each element may be by a separate tube. The fuel supply may be separate by means of a wick system. In another arrangement the heater elements are arranged transversely between an air-fuel supply tube and an exhaust tube or the exhaust tube may be omitted if exhaust direct to atmosphere can be per. mitted. On application of the invention to the tubular heaters of a suit for human wear is described.

Title: Process for the production of products of regenerated cellulose and new surface-active compounds for use therewith
Inventor: JACCARD GASTON
IPC: D01F2/08
Filed: 1963-04-10
Abstract: 1,037,644. Regenerated cellulose filamentary materials. SANDOZ PATENTS Ltd. April 10, 1963 [April 10, 1962], No. 14363/63. Heading B5B. In the production of filamentary materials by spinning or casting viscose into a precipitating bath, there is added to the viscose and/or to the precipitating bath a surface active compound which is an optionally quaternized, sulphoalkylated basic carboxylic acid amide obtainable by sulphoalkylation, especially by sulphoalkylation of a basic amide derived from a carboxylic acid containing 12-18 carbon atoms and an alkylene diamine having 1-4 carbon atoms in the alkylene group, or a polyalkylene polyamine, the diamine or polyamine being N-substituted by alkyl and/or hydroxyalkyl group or groups, each having 1-4 carbon atoms, and having only one primary amino group. Sulphoalkylation may be effected with the acid of a salt of a sulphonic acid having 1-4 carbon atoms and containing only one substituent capable of reacting during the alkylation and whereby the reaction product is quaternized, if desired. Preferred compounds are the sulphoalkylated basic carboxylic acid amide obtainable by sulphoalkylation of lauric acid dimethylamino propyl-amide with a salt of 1-chloro-2-hydroxypropane-3-sulphonic acid and its quaternary ammonium derivatives, and the corresponding compound derived from oleic acid. In general, the surface-active compound may be a derivative of a soap-forming fatty acid, e.g. lauric, myristic, palmitic, stearic and oleic acids, and mono-N-alkylated or mono-N- hydroxyalkylated or asymmetrically di-N-alkylated or di-N-hydroxyalkylated ethylene diamine, propylene diamine and diethylene triamine, especially hydroxyethylaminoethylamine, methylamino propylamine, and 1- amino-3-dimethylaminopropane. For the sulphoalkylation there may be used C 1 -C 4  alkane-aulphonic acid salts containing a halogen atom or an epoxy group in the alkyl radical, e.g. haloethane-, 1-halopropane-3-, 1-halo-2- hydroxy-propane-3-, and 1,2-epoxy propane-3- sulphonic acid salts. Sulphoalkylation may be effected in an aqueous alkaline medium at a moderately elevated temperature. The reaction products contain chiefly tertiary and/or quaternary ammonium compounds which possess at least one sulpho group in the molecule so that they act amphoterically, i.e. are anion-active in an alkaline medium and cation-active in an acid medium. The compounds containing tertiary amino groups may optionally be quaternized by reaction with alkylating agents, e.g. dimethyl sulphate, methyl chloride, benzyl chloride and glycol chlorohydrin. Aqueous solutions of the compounds containing 10- 15% of combined carboxylic acid may be added in a proportion of 0À1-1 g./1 to the lye used in preparation of the viscose, or in a proportion of 0À5-0À75 g./l to precipitating baths.
Patent GB-769212-A (GB)
Title: Improved friction material for brakes
IPC: F16D69/02
Filed: 1954-05-17
Abstract: A friction material for brake linings is formed by a sintered mixture of mullite (3 Al2O3. 2SIO2) and a metallic binder in which said mixture includes a component, particularly molybdenum or tungsten, which acts to inhibit the formation on the friction surface of a high melting point glaze which by causing an excessive rate of torque increase as static friction conditions are approached produces brake chatter.  The molybdenum or tungsten have anti-oxidant properties which prevent the existence of iron in its highest valence form thereby maintaining a lower melting point "glaze" a 12,5 per cent maximum proportion by weight of molybdenum being suggested.  The proportion of ceramic material, predominantly mullite, may be about 43 per cent, the remaining 35-65 per cent being selected from the metals copper, nickel, titanium, zinc or tin of which copper may form up to about 84 per cent, forming a matrix in which mullite particles are embedded.  A second ceramic such as silica may be added, and also a lubricant formed by graphite, hardcoal or lead.  An apparatus for testing specimens of the friction material when raised to an appropriate temperature is described. Specification 740,820 is referred to.

Title: Pigments which fluoresce in ultra-violet light
Inventor: KRANZ JOACHIM
IPC: C07D209/50
Filed: 1966-04-01
Abstract: A colourless pigment which fluoresces yellow in ultra-violet light comprises a colourless organic plastic and a b -aminophthaline having the general formula <FORM:1092689/C4-C5/1> in which R1 denotes a hydrogen atom, a hydroxyl group or a methyl group and the radicals R2 and R3 denote hydrogen atoms or together denote one of the radicals <FORM:1092689/C4-C5/2> and <FORM:1092689/C4-C5/3>  Organic plastic carriers may include polyvinyl chloride, polyacrylonitrile, polyacrylic esters or ureaformaldehyde or melamineformaldehyde resins.  The fluorescent material may be made by condensing products of iminophthalimide with 2-methylpyridine, 2-methylquinoline or 2,6-dimethylquinoline.  The concentration of b -quinophthalines in the whole mixture may be 0.1 to 3%, preferably 0.5 to 2% by weight. In an example a solution of one or more of the b -quinophthalines in a solvent miscible with water (e.g. dimethylformamide, N - methylpyrrolidone, tetrahydrofurane, or ethylene glycol monoethyl ether) may be added to an aqueous dispersion of the plastic.  The mixture is then heated while stirring to approximately 85 DEG  C., the pigment then being filtered off.  To produce compositions which fluoresce in colours other than yellow, a small amount of a prior art substance, such as 4-aminonaphthalic acid n-butylimide, which fluoresces in another colour may be added to the plastic and b -quinophthaline. Reference is made to known pigments consisting of a mixture of polyvinyl chloride and 9,10-dichloroanthracene or di-hydroxyterephthalic esters and also the pigment o-hydroxybenzaldazine.  The pigments can be used as marking inks, for warning signs and traffic signs, or for articles to be sorted automatically.

Abstract: 1502262 Microwave heating THORN ELECTRICAL INDUSTRIES Ltd 1 July 1975 [3 April 1974] 14817/74 Heading H5H A microwave heating apparatus has a heating chamber 10 with a microwave supply, inlet and outlet passages 11, 12 with doors 17, 28 at the ends remote from the heating chamber 10, a driven conveyer 25 extending through the chamber from a feed station 24 within the door of the inlet passage, a feeding device 22, 23, for feeding a unit to be heated from a supply station 20 to the feed station 24, sensing devices 31, 32, 33 responsive to presence or absence of units to be heated at the supply station 20, the feed station 24 and the treatment station 50 within the chamber, and control equipment interconnecting the sensing devices with doors, feeding device, conveyer drive and microwave supply such that detection of a unit at the supply station 20 enables the apparatus to commence a cycle of operations, detection of a unit at the feed station 24 initiates closing of the inlet door and starting of the conveyer drive, detection of the unit at the treatment station 50 and of closed doors initiates supply of microwave energy and absence of a unit at the feed station 24 causes opening of the inlet door if a unit is detected at the supply station 20. As long as units to be heated are presented at the feed station, the cycle is repeated. If no units to be treated are detected at supply station 20, detector 34 in the outlet passageway 12 controls the cycle, with the inlet door being kept closed. The doors are constructed. Fig. 3, to have a flexible conductive panel 39 which by inflation of a circumferential duct 41 is caused to abut a conductive resilient gasket 38 on a door frame 37, thus providing a microwave seal. The operations are in general dependent on the state of inflation or deflation of the duct 41, rather than the mere presence of a door at the inlet or outlet openings 36. Thus for example in starting, the first step of opening the doors is deflation of the seals. Detection of the deflation by pressure switches permits opening of the doors. Microwave energy is supplied and the conveyer started when the seals are again in place and inflated.
