Title: An article for dispensing organosilicon compounds
IPC: C04B41/49
Filed: 1954-01-25
Abstract: Organo-silicon compounds which are: (1) resinous siloxane polymers; (2) liquid siloxane polymers; or (3) disilanes, silmethylenes, silethylenes, silphenylenes, polymeric silanes and polymeric silmethylenes are dispersed in a compressed and liquefied chlorofluoromethane or chlorofluoroethane or mixtures thereof and contained in a closed container equipped with a release valve from which they may be dispensed as a finely divided spray.  Specified halogenated hydrocarbons are those having the formulae CHaClbFc and C2Cl6F6-d, where a is 0 or 1, b is 1, 2 or 3, c is 1 or 2 and d is 2 or 3.  The organo-silicon compound may be dispersed in another organic solvent which is then dispersed in the halogenated hydrocarbon.  In examples: (1) trimethylsiloxy end-blocked phenylmethylpolysiloxane was dispersed in a mixture of CCl3F and CCl2F2 in a closed container to give a 30 per cent dispersion.  The container was used to lubricate by spraying the locks of car doors and trunks.  (2) As in (1) but using trimethylsiloxy and blocked dimethylpolysiloxane which was used as a mould release agent.  (3) As in (1) but using trimethylsiloxy end-blocked methylhydrogenpolysiloxane which was used to render textiles water-repellent by spraying and heating to 100 DEG  C.  (4) A mixture of 40 per cent of a resin derived from 55 mol. per cent C6H5CH3SiCl2, 15 mol. per cent C6H5 SiCl3, and 30 mol. per cent CH3SiCl3 and 60 mol. per cent of a resin from equimolar proportions of (CH3)2SiCl2, CH3SiCl3 and C6H5SiCl3 together with a small proportion of cobalt naphthenate was made into a 40 per cent solution in toluene and the solution made into a 15 per cent solids dispersion in the fluorocarbon mixture of Example (1). The dispersion was used for spraying bread pans, the coating being cured at 400 DEG  F. for an hour.  (5) A mixture of 33 parts of a co-polymer of (CH3)3SiO 1/2 and SiO2 units of CH3/Si ratio 1.2, 50 parts trimethylsiloxy end-blocked dimethylpolysiloxane fluid and 17 per cent tetrabutyltitanate was made into a 60 per cent solution in Stoddard solvent and dispersed in equal parts of CCl2F2 and CClF2CClF2 to give a 10 per cent polysiloxane dispersion.  The dispersion was used to render leather water-repellent.  (6) A partially alkoxylated mixture of by-product chlorosilicon compounds described in Specification 714,461 was mixed in the proportion of 67 parts with 33 parts of the copolymer of Example (5), dispersed in the fluorocarbon mixture of Example (1) and used to waterproof masonry.

Title: Application of base exchange artificial resins for purifying aqueous solutions
IPC: B01J39/19
Filed: 1937-01-26
Abstract: Water-insoluble artificial aldehyde resins containing a sulphonic acid group or groups are manufactured by condensing an aromatic compound, containing at least one sulphonic acid group and having a tendency to condense, with an aldehyde or agent yielding it, or by treating an artificial aldehyde resin with a sulphonating agent.  In examples: (1) phenol-p-sulphonic acid is condensed with formaldehyde; (2) phenol is sulphonated and the product is condensed with formaldehyde; (3) naphthalene is sulphonated and the product is condensed with formaldehyde; (4) a resin made by condensing m-phenylenediamine with formaldehyde is sulphonated with fuming sulphuric acid.ALSO:Cation exchange is effected in aqueous solutions by passing the solution through a water-insoluble artificial aldehyde resin (i.e. a resin prepared from aromatic compounds and aldehydes) containing a sulphonic acid group or groups, preferably one having a large internal surface and a granular structure.  Regeneration may be effected by means of suitable acids or salt solutions.  The resins may be prepared by condensing an aromatic compound, containing at least one sulphonic acid group and having a tendency to condense, with an aldehyde or agent yielding it, or by treating an artificial aldehyde resin with a sulphonating agent.  In examples: (1) phenol-p-sulphonic acid is condensed with formaldehyde; the product may be used for extracting calcium chloride from solution, and regenerated with acid or common salt solution; (2) phenol is sulphonated and the product condensed with formaldehyde, yielding a product similar in properties to that of (1); (3) naphthalene is sulphonated and the product is condensed with formaldehyde; the product absorbs calcium and copper from solution; (4) a resin made by condensing m-phenylenediamine hydrochloride with formaldehyde is sulphonated with fuming sulphuric acid; the product absorbs copper from a dilute ammoniacal copper solution, e.g. the waste liquor from a copper artificial silk factory.

Title: Manufacture of colouring matters
IPC: C09B47/06
Filed: 1936-07-08
Abstract: The process described in the parent Specification (the manufacture of stable metal phthalocyanines by heating together a phthalic anhydride, or a corresponding free acid, or a monoester thereof, or an ammonium salt thereof, or an amide or imide of the said acid, or an o-cyanobenzoic acid or an ammonium salt or ester thereof with urea or a heat decomposition product thereof (other than ammonia) and a substance consisting of or containing a metal adapted to give a stable metal phthalocyanine) is modified by adding boric acid in small quantity to the reaction-mixture.

Abstract: 583,865. Potato harvesters. BONELLA, A. G. Feb. 10, 1944, No. 2479. [Class 6 (iii)] A potato harvesting machine comprises a reticulated screening drum 4 rotatable about an axis extending transversely of the machine and adapted to receive the contents of the drill delivered to it by a rotatable feed element 1, the drum screen serving to free the potatoes from soil and the soil-free potatoes then passing, as the drum rotates, to the other side of the drum to an outlet 18 which rotates with the drum, whereby the potatoes are delivered in heaps on the ground each time the outlet reaches it lowermost position. In the construction shown the feed element 1, which operates behind a fixed share or sock 15, is arranged at an angle to the line of travel of the machine 4 and is power-driven. The reel is slightly dished and comprises radial spokes 12 with wire between to constitute a riddle. Potatoes pass from the reel to the cone-shaped drum 4 which rotates on an axle 7 so inclined that the underside of the wheel is parallel to the ground. The drum, which is joined to a central hub by spokes 8, is covered with wire mesh, and is fitted with a ring 6 which engages the ground, causing the drum to rotate as the machine progresses. Both inlet and outlet ends of the drum have inwardly directed peripheral flanges, and that at the outlet end has the opening 18 through which the potatoes fall, being guided thereto by a curved baffle 20. The potatoes pass through prongs 19 which serve to lift haulms upwards, the haulms dropping off when the prongs are pointing downwards.

Abstract: 579,343. Cutting-machines for leather &c. COLLINSON, F. B. Jan. 29, 1945, No. 2756/44. [Class 31 (i)] A machine for cutting shapes such as leather soles from sheet material is constructed with a cutting member 16 having knives arranged as shown in Fig. 3 to form multiple pattern of the shapes, and with a pressing member which progressively forces the blank B against the knives 16 as these.are traversed together with the blank relatively to the pressing member, the material being bent about an axis transverse to the direction of movement of the sheet through the machine. In Fig. 5, the knives are fixed to the reciprocating bed 15 of a planing machine, and the leather bend B is kept free from curves by being fed over rods 28, the front edge of the bend being slit and secured to a hook 33 on the bed. The bend is forced against the knives by a curved anvil 24 adjustably secured to an extension of a tool holder 14, and the cutting is completed by a pressure roller 17 adjustably .mounted and supported by a counter pressure roller 18. Spring-pressed studs are arranged to eject the cut sole shapes which may be delivered by a conveyer. In a modification, Fig. 8, the cutting member 15 with knives .16 is mounted in .a segmental corner 11, and the material is supported as in Fig. 5 and fed between the carrier 11 and pressure roller 17, the carrier being driven by a gear 37 and an internal gear 38. A platform 39 is provided for the operator who controls the feed, and a signal device may be used to warn the operators when the machine is .to be started. The dies may be arranged to cut identification .notches 29, Fig. 3, in the sole blanks, and an adjustable side gauge may be used in the machine for confining the action of the cutters to certain parts of the bend B.
