Title: Improvements in or relating to methods of forming an adherent layer on a sintered ceramic body
IPC: C04B41/52
Filed: 1959-07-20
Abstract: A sintered ceramic body such as alumina is coated with an adherent layer by applying a powdered mixture of a metal or metal compound and a ceramic which ceramic has a particle size less than 5 microns and a melting-point not lower than that of the ceramic body, and heating the body to below its melting-point.  The ceramic powder may be alumina, magnesia or zirconia and form up to 50% by weight of the mixture.  The metal powder preferably less than 5 microns is tungsten or molybdenum mixed with iron or manganese.  Bonding is effected by heating to below 1400 DEG  C. in a humid hydrogen - nitrogen atmosphere.  A powder metal mixture of molybdenum and manganese may be applied to the first layer and bonded at 1300 DEG  C. and a further powder metal layer of nickel may be applied and bonded at 900-1000 DEG  C.  The coated ceramic can then be soldered or brazed to another metallized ceramic or metal.

Title: Unbonded fibrous assembly
IPC: D04H1/58
Filed: 1967-05-30
Abstract: 1,140,710. Fabric laminates. E. I. DU PONT DE NEMOURS & CO. 30 May, 1967 [1 June, 1966(2)], No. 24799/67. Heading B5N. [Also in Divisions D1 and F4] An unbonded web comprises crimped staplelength orientated synthetic polymer fibres having at least a partial coating of an unorientated synthetic polymer having a melt temperature of at least 70‹ C. but less than the fibre stick temperature of the fibre polymer, e.g. within 5-50‹ C. of the latter. The fibres have an average length of at least one inch, a maximum retractive coefficient of not more than 30, a crimp frequency of at least 3 crimps per inch and an average crimp index of at least 3%. The web has a density of not more than 1 1b/cub. ft. The web is made by forming a tow of a filamentary polymer, crimping filaments in the tow, separating the crimped filaments, at least partially coating the filaments with the lower melting polymer, transversely cutting the tow to form sections of staple length fibres, e.g. 1-6", then opening and mechanically distributing the fibres to form the web, the method including, prior to the web forming step, annealing the filamentary polymer at an elevated temperature in a relaxed state so as to provide the maximum retractive coefficient of not more than 30. The lower melting polymer can be applied in fibre form or by spraying, e.g. as a solution or aq. dispersion or by dipping an opened tow in a solution of the polymer, squeezing and drying, e.g. at 120-160‹C. under a tension of not more than 0À009 (see Fig. 5, not shown). The lower melting polymer can be polyolefins, acrylic resins, acrylic terpolymers, polyesters, copolyesters, polyamides, copolyamides, vinyl polymers and copolymers. The filaments can have a denier of 1-50 denier per filament and is preferably formed from the same class of polymer as the low melting polymer. The filament tow can be drawn and may be annealed once or twice by air, water or steam at a temperature above 80‹ C. and deregistered into separate filament groups. The filaments may become crimped during annealing. In Ex. 14 trilobal filaments are used to form the web. The fibres can be formed into the web by carding, garnetting or cross-lapping. The fibres can be removed from the carding machine and collected on a perforated belt by an air stream so as to reform the web. The web can be bonded by heating to melt the lower m.p. polymer. During bonding an air stream can be forced through the web to minimize compaction. The web can be bonded whilst in a mould. The web can contain 0-95% uncoated or monocomponent filaments. The web can be converted into slivers, bonded yarns or knitted tufted and woven fabrics or formed into a bonded block of aligned fibres which can be sliced and bonded with the fibres end-on to woven cotton cloth with an ethylene terephthalate/ethylene azelate adhesive, see Examples 15-18. The Specification also discloses corresponding webs formed of non-annealed fibres.

Title: Improved germicidal compositions
Inventor: GRAHAM ARCHIBALD ROBERT
IPC: A01N31/12
Filed: 1950-10-13
Abstract: The invention comprises isomeric mixtures of di-iso-decyldimethyl ammonium halides or hydroxides.  The isomeric mixtures of the desired products may be prepared from an isomeric mixture of iso-decaldehydes produced by an Oxo reaction between carbon monoxide, hydrogen and a branched chain olefine containing nine carbon atoms, e.g. a propylene trimer or a mixture of propylene trimers of boiling range between 120 DEG  and 150 DEG  C. at atmospheric pressure.  In the example a mixture of iso-decaldehydes obtained by treating a mixture of propylene trimers by the Oxo process is converted to a mixture of iso-decylamines by heating in admixture with ammonia, Raney nickel and methyl alcohol with hydrogen under pressure, heating the product with a further quantity of the iso-decaldehyde mixture, Raney nickel and methyl alcohol and hydrogen at elevated pressure to obtain di-iso-decylamines.  A mixture of N-methyl di-iso-decylamines is obtained by heating the latter with formic acid and aqueous formaldehyde, adding sulphuric acid to the product which is then steam-distilled and separating the oil formed after making the residue alkaline.  The mixture of N-methyl di-iso-decylamines is converted to mixtures of di-iso-decyldimethyl-ammonium chlorides, bromides or iodides respectively by heating in a Carius tube with methyl bromide and ethyl acetate or methyl chloride and methanol or by allowing a mixture with methyl iodide to stand.  The mixtures of halides may be converted to the corresponding hydroxides, e.g. by treatment with an aqueous suspension of silver oxide.  The halides or hydroxides may be employed in germicidal and washing compositions (see Groups III and VI).ALSO:Detergent compositions comprise isomeric mixtures of di-iso-decyl-dimethylammonium halides or hydroxides (see Group IV (b)) in admixture with other detergent and or alkaline washing compounds.  The isomeric mixtures of di-iso-decyldimethylammonium halides or hydroxides are compatible with water-soluble silicates and phosphates when dissolved in excess sodium carbonate solution.ALSO:Germicidal and detergent compositions comprise isomeric mixtures of di-iso-decyldimethylammonium halides or hydroxides (see Group IV(b) in admixture with other detergent and/or alkaline washing compounds.

Abstract: 1,221,583. Endless conveyers. FR. WINKLER K.G. SPEZIALFABRIK FUR BACKEREIMASCHINEN UND BACKOFEN. 27 May, 1968 [9 Feb., 1968], No. 25340/68. Heading B8A. Unbaked dough pieces are transferred from trays on a roller conveyer 34 to temporarily stationary carriers 10 of an oven conveyer by an endless conveyer belt 3 mounted on a carriage 2 to move the belt between the respective conveyers. A belt tongue at one end of the conveyer 3 picks up dough pieces from the trays as the conveyer moves in the direction e and the carriage moves in the direction c, and a belt tongue at the other end of the conveyer 3 delivers dough pieces to the carriers as the conveyer moves in the direction e and the carriage in the direction c and also picks-up baked dough pieces from the carriers when the conveyer moves in the direction d and the carriage moves in the direction b. The baked dough pieces are delivered, at a position intermediate the conveyers, to a shoot 39 feeding an endless conveyer 36. If it is desired to turn over the dough pieces on delivery to the carriers 40, the carriage 2 on its movement towards the carriers engages a ramp 19 and rails 17 to raise the conveyer 3 above the carriers (position 3<SP>111</SP>) so that the dough piece turn over as they are discharged. An auxiliary conveyer 13 positioned above said one end of the conveyer 3 assists in the pick-up of the dough pieces. Synchronization of the movements of the carriage 2 and the conveyer 3 with the oven conveyer is achieved by including in the control circuits therefore switches operated by cams 31, 43 driven respectively by the drive motor 30 for the carriage and the oven conveyer. A drive motor 10 for the conveyer 3 is mounted on the carriage 2. In a modification the said other end of the conveyer 3 has a pusher 44 such that when the carriage is withdrawn to the position 3<SP>11</SP> the trays loaded with unbaked dough pieces may be pushed from the conveyer 34 to the carriers 40.
