IPC: D06F47/06
Filed: 1949-07-08
Abstract: 666,347. Washing and drying machines. AVCO MANUFACTURING CORPORATION. July 8, 1949 [Aug. 20, 1948], No. 18092/49. Class 138 (ii). A washing - machine having a collapsable bag 10 for extracting liquid from the clothes comprises a hollow vertical member 32 having a major outlet 33 into the hollow portion at the top thereof and a smaller outlet adjacent the bottom thereof so that on collapsing of the bag most of the water flows out through the upper outlet. The bag 10 is so arranged that its upper portion will collapse inwardly and contact the hollow member 32 (as shown in Fig. 3) before the bottom portion of the bag is lifted and a fold 50 may be provided in the side wall of the bag to ensure that the bag functions in this way. The clothes are thus held below the open top of the member 32 during the initial draining of liquid and scum from the top. In the example the hollow member 32 comprises an open topped agitator 31 provided with perforations 35 in its outwardlyextending portion. These perforations lead to a region 36 separated from an outlet 34 by a cylindrical wall 37 and liquid drains to the outlet 34 through notches 38 cut in the bottom face of the wall 37. The outlet 34 is connected by a conduit 40 to an air-and-liquid pump 39 whose outlet 41 is connected with a standpipe reservoir 42 having an outlet 43. The pump 39 is driven through a one-way drive pulley 44 and a belt 45 by a motor 30. On reversing the motor, the pump 39 stops and drive means for the agitator is actuated. This means consists of a belt 29, a one-way drive pulley 28 and a worm 27 driving a worm-wheel 26 carrying a crank 25. This crank imparts an oscillatory motion to a rack 24 which drives a pinion 23 mounted on a shaft 21, the upper end of the shaft being splined to carry the agitator 31. The bag 10 is supported by an outer member 13 and its open top is closed by a cover 51. Liquid is supplied to the bag through an opening 55 in cover 51, the opening 55 having a valve closure and vacuum release 57 actuated by a solenoid 58. With closure 57 lifted a waterdirecting tube 59 directs a stream of water into opening 55, water being supplied through a line 60 leading from a mixing valve 61. Valve 61 may be actuated by solenoids 62 and 63, actuation of the former providing hot water for washing and actuation of the latter providing mixed water at a lower temperature for rinsing. Specification 640,020 is referred to.

Patent GB-451723-A (GB)
Title: Stabilization of vinyl resins and compositions produced thereby
IPC: C08K5/098
Filed: 1935-06-25
Abstract: Polymerization products of vinyl esters, of improved resistance to heat or light, are manufactured by intimately mixing a polymerization product of at least one vinyl ester (including vinyl halides but excluding esters of unsaturated aliphatic carboxylic acids containing more than 12 carbon atoms) with a small amount, e.g. about 0,5--3 per cent, of one or more alkali metal, cadmium, lead or manganese salts of a weak organic carboxylic acid, e.g. the stearates, oleates, linoleates, ricinoleates, palmitates abietates, oxidized linoleates and ricinoleates, acetylated ricinoleates, lactates, succinates and laurates of the said metals, also lead adipate, benzoate, tartrate and acetate.  These salts may be used in conjunction with other stabilizers, e.g. other metal soaps such as copper oleate, esters such as butyl or methyl salicylate, or urea.  The mixtures may be rendered more alkaline, if desired, by addition of free alkaline oxides, hydroxides or other alkaline compounds.  The stabilizers may be incorporated in the resins during their manufacture or subsequent thereto, e.g. by mixing the dry resin and stabilizer in a masticator or on heated differential rolls, or by mixing in the presence of a solvent, e.g. acetone, or a fluid non-solvent for the resin, the resin and stabilizer being precipitated from the solution or suspension by adding water.  The stabilizers also serve as lubricants, and may be used in such quantities that they act also as plasticizers.  In examples: (1) an interpolymer of vinyl chloride and acetate, precipitated by water from an acetone solution of the resin, is mixed with lead oleate (obtainable by reacting oleic acid with litharge, or, in a specially suitable form, by reacting lead acetate with sodium oleate in aqueous solution); (2) an interpolymer of vinyl chloride and acetate is mixed with cadmium laurate; (3) a refined vinyl resin, obtained by extraction of the resin of (2) with toluene and acetone, is mixed with lead stearate, ultramarine blue and titanium dioxide. Specification 450,856 is referred to.  The Specification as open to inspection under Sect. 91 comprises the stabilization of polymerization products of vinyl esters in general (including vinyl halides) by the admixture of alkali metal, alkaline-earth metal, cadmium, lead, manganese or antimony salts of weak organic acids in general.  Additional salts specified are basic lead carbonate, barium succinate, calcium lactate, calcium lactophosphate and strontium oleate.  This subject-matter does not appear in the Specification as accepted.

Patent GB-747768-A (GB)
Title: Reduction of aminoketones
Inventor: FRIEDMANN CHARLES AUBREY
Filed: 1953-07-01
Abstract: An organic acid salt of adrenalone or noradrenalone is catalytically hydrogenated to the salt of the corresponding amino alcohol in the form of a suspension or slurry in a medium in which the amino alcohol salt obtained is relatively more soluble. Specified organic acid salts are the oxalate and the tartrate, water being preferably used as the reaction medium for the oxalate and aqueous methanol, ethanol or isopropanol, containing preferably 10-40 per cent w./w. water, for the tartrate.  The suspension or slurry may contain 15-30 per cent w./v. of the salt to be hydrogenated and the hydrogenation is preferably conducted at 40-60 DEG  C. under slight superatmospheric pressure using a palladium-charcoal catalyst.  The solutions of amino alcohol organic acid salts which are obtained may be decomposed with dilute ammonia to give the free bases.  In examples: (1) adrenalone oxalate is suspended in water and reduced with hydrogen in the presence of a palladium-charcoal catalyst.  Free d,l-adrenaline is recovered from the reaction mixture by standard procedure.  (2) Noradrenalone oxalate is similarly reduced and d,l-noradrenaline is recovered.  (3) Noradrenalone d-bitartrate is suspended in 80 per cent methanol and similarly reduced.  The resulting solution is filtered and evaporated, and the residue on fractional crystallization from aqueous methanol gives d-noradrenaline-d-bitartrate as the less soluble fraction and l-noradrenaline d-bitartrate as the more soluble fraction. d-Noradrenaline and l-noradrenaline are recovered by treatment with aqueous ammonia and the l-noradrenaline is characterized by conversion to its hydrochloride.  Noradrenalone-d-bitartrate is prepared from d-tartaric acid and noradrenalone hydrochloride. The Provisional Specification also refers to the use of other solvents, such as water, in the resolution of dl-noradrenaline-d-bitartrate, and to the use of platinum or Raney-nickel as hydrogenation catalysts in the reduction of dl-noradrenalone-d-bitartrate.
