Title: Sustained action detergent product
IPC: C11D1/75
Filed: 1968-05-14
Abstract: 1,224,777. Sustained action detergent. ARMOUR GROCERY PRODUCTS CO. 14 May, 1968 [15 May, 1967], No. 22738/68. Heading C5D. A dry detergent composition comprises, by weight, 5-20% of a detersive surface active agent (which is one of more conventional soaps, anionic synthetic detergents and/or nonionic synthetic detergents), 0À5-16% of a suds booster (which is a fatty ethanolamide and/or an amine oxide), the balance of the composition consisting of inorganic builders and fillers, with 10-60% of said builders and fillers being tripolyphosphate, and 20-75% of said tripolyphosphate being in the form of discrete particles encapsulated by a polymeric film so that the encapsulated tripolyphosphate, in the presence of water, is gradually dissolved in the water over an extended period of time. Suitable soaps for use as the detersive surface active agent are water-soluble ammonium, alkali metal or organic base salts of C 12 -C 18  fatty acids. Suitable anionic synthetic detergents are alkyl aryl sulphonates, alkyl sulphates, sulphonated fatty acid amides and sulphonated monoglycerides, while suitable nonionic synthetic detergents are polyoxyethylene ethers of fatty alcohols or of alkylphenols, fatty acid/ethylene oxide condensation products, condensation products of ethylene oxide with fatty acid esters of polyhydric alcohols or with sugars, and fatty acid diethanolamides. The preferred synthetic detergents are C 12 -C 14  alkyl benzene sulphonates. The suds booster may be a fatty acid mono- or di-ethanolamide, or an amine oxide or morpholine oxide containing one or more C 6 -C 18  alkyl radical. Preferably the tripolyphosphate is in the form of its sodium salt and encapsulation is with gelatin, polyvinyl alcohol, polyvinyl acetate, carboxymethyl cellulose or hydroxyethyl cellulose. Different rates of release of the encapsulated tripolyphosphate may be achieved by the use of encapsulating materials having different rates of dissolution or by the use of different thicknesses of encapsulating film. Additional builders such as sodium sulphate and tetrasodium pyrophosphate may be present. The detergent composition may be in the form of discrete granules or a tablet. Where a fully self-disintegrating tablet is desired, an effervescent composition can be incorporated. This may comprise at least one carbonate salt (e.g. sodium carbonate, bicarbonate or sesquicarbonate) and at least one water-soluble acidic material (e.g. sodium dihydrogen phosphate, sodium acid pyrophosphate, citric acid, tartaric acid or fumaric acid). Brighteners, pigments and perfumes may also be present.

Title: Method and arrangement for the identification of speech
IPC: G10L15/00
Filed: 1959-07-03
Abstract: 916,781. Recognising speech sounds. STANDARD TELEPHONES & CABLES Ltd. July 3, 1959 [July 10, 1958], No. 22926/59. Class 106 (1). In apparatus for recognising speech sounds the speech signals after compression is applied to four band-pass filters F1, F2, F2,3 and F3, each of which has a wide band width and the output of each filter is applied to a detector D which produces a pulse when the signal changes polarity to start a pulse generator J, the counter C serving to count the pulses until the next pulse, the output of the counter, representing the instantaneous wavelength of the filter output signal, being entered into a shift register SH. A recognition circuit TR connected to the shift register stages produces outputs on leads L representative of the sounds detected. The detector D may produce signals of both polarity transitions. The output pulse appears on leads 1, 2 and 3. The first starts the generator J, the third opens the gates G to pass the contents of the counter into the three parallel shift registers and the pulse on line 2 resets the counter in preparation for the next cycle. Entry into the shift registers may be made at each cycle or only when the contents of the counter differ from the previous value.

Abstract: 222,510. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Kirwer, C.). Sept. 28, 1923, [Convention date]. Joints formed by welding.-A glass to metal seal between tubular members is formed by folding a portion of glass over the end of the metal tube, and fusing or welding it thereto, the glass tube being fused subsequently to the glass portion. As shown in Fig 2 a copper tube 4 has a knife-edge portion 10, on both sides of which a folded glass-portion 11, 12 is welded. This is effected as shown in Fig. 3 by inserting the edge in the end portion 11 of a tube 15 and heating in a flame, the glass being worked and rolled on the metallic surface by means of a metal or graphite plate until the surface is fully wetted by the glass. The tube 15 is then severed and the portion 12 folded over and sealed in a similar manner to the inner surface of the edge 10. The glass flange thus formed may be welded by a butt-or lap-joint to a glass tube. In the joint shown in Fig. 9 the end 22 of a thin portion of the tube 4 is left out of contact with glass 5.

Abstract: 1,082,928. Photo-electric detection of extraneous matter in ampoules. FARBENFABRIKEN BAYER A. G. June 1, 1965 [June 4, 1964]. No. 23315/65. Heading G1A. To detect extranepus matter in a liquid in an ampoule, the ampoule is first rotated in a vertical position and then stopped, the matter after being lifted into suspension then falls to the bottom and in so doing passes through a horizontal light curtain close to and extending over the bottom of the ampoule. Particles over a given size are detected by means of a photo-diode or -transistor detecting changes in intensity of the light curtain and passing the resulting signals to a threshold amplifier. In order to obtain parallel rays of light within the ampoule, which acts as a cylindrical lens, the source of light is placed at the focal point of the ampoule. The vortex created in the ampoule by the rotation is allowed to subside so that its peak is above the light curtain before measurement is taken.

Title: Improvements in or relating to a process for the production of compounded aqueous dispersions of or containing rubber and the products obtained thereby
IPC: C08L7/02
Filed: 1935-08-21
Abstract: A creaming-agent such as pectin, gum tragacanth, alginate, or Irish moss, is added to an unvulcanized aqueous rubber dispersion concurrently with or subsequently to the addition of compounding ingredients to the dispersion, the agent being added in a proportion effective in the creaming of uncompounded latex.  This treatment appears to effect temporary association of rubber globules with particles of compounding ingredients.  The resulting composite particles may be lighter than, heavier than or equal in specific gravity to the aqueous serum of the dispersion, so that the composite particles may cream up or down or not at all.  The compounding ingredients may be oils, sulphur, accelerators, activators and fillers which may be formed in the dispersion by the interaction of suitable reagents, in which case the creaming agent may be added immediately before or concurrently with the final reagent.  The creaming may be expedited or modified by heat, agitation or centrifuging.  The latex concentrates described in Specifications 219,635 and 290,313, [both in Class 70], may be used.
