Title: Process for the production of detergent tablets
IPC: C11D17/00
Filed: 1964-12-29
Abstract: Detergent tablets are prepared by compressing a detergent composition into tablets, treating the compressed tablets with superheated steam at a temperature above 450 DEG  F. for less than 10 seconds, and then cooling the steam-treated tablets for at least half a minute to reduce the tablet temperature to ambient temperature, the cooled tablets having substantially the same moisture content as before the steam treatment.  The tablet-forming composition may comprise non-soap organic anionic or non-ionic detergent, including C9- 15 alkylbenzene sulphonates, fatty acyl isothionates, alkyl sulphates fatty acyl isothionates, alkyl sulphates and sulphonates, dialkyl sulpho-succinates, sulphated or sulphonated monoglycerides, fatty alkyl sulphocarboxylates, methyl taurides; polyoxyethylene condensates with alkyl phenols, polyoxypropylene, propylene oxide/ethylene diamine reaction products, and straight or branched chain C8- 18 alcohols; and "Pluronics" (Trade Mark). In the anionic detergent the cation may be sodium or potassium. The compositions may also contain soap, sodium sulphate, sodium silicate, sodium tripolyphosphate, lauric myristic isopropanol-amide, alkyl dimethylbenzyl ammonium chloride, sodium carboxymethyl cellulose, and other conventional additives such as colour, perfume, optical brighteners &c.

Abstract: 1,250,039. Wells &c. VETCO OFFSHORE INDUSTRIES Inc. 28 Oct., 1969 [17 March, 1969], No. 52692/69. Heading E1F. An apparatus for supporting a casing hanger comprises a housing 18, 17 and a split ring 15 shiftable from an inoperative position, Fig. 3, to a constricted operative position, Fig. 2, in which it provides a seat for the casing hanger (not shown). Fluid supplied through a passage 43 to a port 44 raises an annular piston 40 and a constrictor ring 28 which cams the ring 15 inwardly to form the seat, Fig. 2. A flange 30 on the ring 28 locates above a shoulder 38 on the ring 15 to prevent a return to that original position when the pressure in the passage 43 is relieved. A casing hanger supported by the ring 15 is held down by a lower split ring 13. When the casing is cemented, circulating fluid is passed through conduits 62. In a modification the ring 15 is formed as two concentric coupled split rings, and the port 44 is provided with a non-return valve. The apparatus is adapted for subaqueous work.

Abstract: 1321629 Preparing α-Aminobenzylpenicillin E R SQUIBB & SONS Inc 6 Nov 1970 [12 Nov 1969] 52935/70 Heading C2A α-Aminobenzylpenicillin is prepared by reacting the reaction product of 6-aminopenicillanic acid or its tertiary amine salt and an aromatic aldehyde which does not contain an α-hydroxy group, with phenylglycine N-carboxy anhydride in a biphasic solvent system comprising 30 to 70% by volume of water and 70 to 30% by volume of a water-immiscible chlorinated alkane having not more than 4 carbon atoms and not more than 3 chlorine atoms on a single carbon atom, and separating the desired product from the aqueous phase. Suitable aldehydes are benzaldehyde, o-, m- or p-chlorobenzaldehyde, p-anisaldehyde and piperonal. The tertiary amine salt of the 6-aminopenicillanic acid is preferably that of a C 7  to C 10  tert. amine, e.g. t-octylamine or t-nonylamine. The chlorinated alkane may be chloroform, trichloromethylene, ethylene dichloride or preferably methylene chloride, and usually comprises about 50% by volume of the biphasic reaction medium. The reaction is carried out at pH 4 to 6 and about 1‹ to 5‹ C. The starting material is prepared by reacting the aldehyde and the tert. amine salt of 6-APA in aqueous solution and the product crystallizes out. This material is then used for the inventive process in about equimolar proportion to the N-carboxyanhydride. After reaction the α-aminobenzylpenicillin is isolated from the separated aqueous phase by concentrating and crystallization, when it is obtained as the trihydrate.

Abstract: 557,622. Melamine. BRITISH INDUSTRIAL PLASTICS, Ltd. April 27, 1942, No. 5339. Convention date, May 28, 1941. [Class 2 (iii)] In the manufacture of melamine by heating a solution of cyanamide or dicyanamide in a solvent comprising liquid ammonia, the reaction is conducted in an autoclave having a rotating agitator whose bearing is accessible to the reactants and which is lubricated by means of a water soluble lubricant. The product is washed with water and hence is not contaminated with the lubricant. Examples of the latter are ethyleneglycol, glycerine, triethanolamine, mannitol, polyethyleneglycol and Turkey red oil. When organic hydroxy compounds are used they form a water soluble complex with any iron that may be present, which is thus removed (c.f. the process of Specification 554,262). An autoclave of known type which may be used is described.

Abstract: 1444523 Silver alloys; coating by sintering E I DU PONT DE NEMOURS & CO 24 Dec 1974 [27 Dec 1973] 55854/74 Headings C7A and C7D [Also in Division C1] A highly adhesive conductor on a dielectric substrate consists of a powder composition of pure silver and a Pd/Cu co-precipitated alloy in the ratio Ag:Pd/Cu of 1:0À1 to 0À5 in an inorganic binder. The Pd/Cu alloy powder is produced by simultaneous co-precipitation from solutions containing the salts of Pd and Cu in the desired proportions, using reductants such as dihydrazine sulphate, sodium borohydride amine boranes &c., preferably at a temperature of 55-80C with an initial pH of 4À5- 8.0 and with the Pd<SP>++</SP> concentration 14-35 g/l and a Cu<SP>++</SP> concentration of 10-28 g/l. The Pd/Cu coprecipitate powder should contain at least 35% Pd, and normally, up to 75% Pd. The silver and Pd/Cu powders with the binder, usually a glass, are normally dispersed in inert vehicles by mechanical mixing, the ratio of solids to liquids being 0À1-20 parts by weight solid per part by weight vehicle. The dispersions may be deposited on dielectric ceramic substrates, such as alumina, barium titanate or zirconate, lead zirconate, strontium titanate, calcium titanate or zirconate &c., by conventional screen or stencil printing, after which the printed substrate may be fired in air to sinter the metallizing compositions and form continuous conductors adherent to the substrate. Firing is carried out below the melting point of the metal used, but high enough to sinter, and is frequently 850C with 5-10 minutes at peak temperature. The use of Pd/Cu co-precipitate alloy is said to produce conductors with greater solderability, better adhesion and higher resistance to solder leaching than mechanical mixtures of Pd and Cu powders, and also to give improved surface smoothness.

[Also in Division B2] In a vertical classifier for dry pulverulent material of the kind described in Specifications 923,331 and 926,290, separated coarse particles contained in an annular discharge chamber 43 are prevented from contaminating separated fine particles contained in a discharge chamber formed by the interior of a fan housing 12 by means of an annular pneumatic seal chamber 85 and of a barrier disc 88 extending from the classifier rotor for rotation in the chamber 85. The rotor includes a flanged ring 35 carrying the disc 88 on the lower surface of its flange and, on the upper surface thereof, a segmental ring 41 carrying vertical radial blades 42, which cause centrifugal discharge of the coarse particles. The chamber 85 is bounded by upper and lower plates 81, 86 which extend into close proximity to surfaces of the ring 35 which are formed with one or more annular grooves 89 providing further pneumatic sealing by setting up eddy currents in the air flow drawn from the seal chamber 85 into the chamber 43 and the interior of the fan housing 12. The annular grooves could alternatively be formed on the surfaces of plates 81, 86. Air enters the chamber 85 through an annular slot 87. In operation of the classifier, reduced air pressure is created in the chamber 43 by rotation of the blades 42 and in the interior of the housing 12 by virtue of the rotation of pegs or rods 37 which support the ring 35 and due to a suction source connected to the fan housing. Any coarse particles accidentally escaping from the chamber through the space between the plate 86 and the ring 35 fall on the disc 88 and are thrown centrifugally outward through the air inlet slot 87 without the possibility of being drawn into the interior of the housing 12.
