IPC: B01J2/00
Filed: 1970-04-20
Abstract: 1299746 Encapsulated materials MINNESOTA MINING & MFG CO 20 April 1970 [21 April 1969 8 May 1969] 18781/70 Heading ASE [Also in Divisions B8 and Cl] Capsules containing a liquid which is slowly released over a long period are made by encapsulating the liquid in a mantle composed of crystalline polyolefine and a compatible hydrocarbon resin, e.g. a petroleum resin, terpene resin or an indene or coumarone-indene resin. Optionally, a hydrocarbon wax, desirably of M.W. in the range 300 to 1500, may also be present. The liquid may in particular be a fertilizer or herbicide, those specifically mentioned being 2,4-dichloro-phenoxy acetic acid and trichloroacetic acid salts, 1,1'-ethylene- 2,2'-dipyridinium bromide (Diquat) and a fertilizer mixture comprising KCI, urea and NH 4 H 2 PO 4 . The capsules may be prepared by conventional methods, e.g. by subdividing a biliquid column, the outer portion of which is liquid encapsulating material, the inner portion being the liquid to be encapsulated and solidifying the encapsulating material.

Filed: 1956-06-18
Abstract: 805,276. Mechanical switches, without quickaction. MORLE, C. W. (Oak Mfg. Co.). June 18, 1956, No. 18789/56. Class 38 (5). A rotary switch has two concentric circles of fixed contacts arranged to be bridged by a moving contact ball. The fixed contacts 34, 41 are secured in desired slots 25, 27 to project from a fixed member 20 and the two series of contacts 34, 41 are bridged by a ball or balls 43 retained in apertures 45 of a plate 46 by spring members 57. The contacts 41 may each extend to cover more than one slot 27. Spring members 57 may retain more than one ball 43 and will then interconnect the balls. The members 20, 46 are held in their relative planes by a coupling member 51 which has a shoulder 52 engaging the outer face of the member 20 and staking fingers 54 which extend through apertures 55 in the plate 46 and are then spread.

Patent GB-734187-A (GB)
Title: Improvements in the manufacture of organic phosphorus compounds
Inventor: COATES HAROLD
IPC: C07F9/535
Filed: 1951-08-09
Abstract: Alkyl phosphorus tetrafluorides are obtained by reacting a complex compound derived from an alkyl chloride, phosphorus trichloride and anhydrous aluminium trichloride with hydrogen fluoride.  The alkyl phosphorus tetrafluoride may be converted into an alkyl phosphonyl compound by the introduction of oxygen, e.g. by reacting with sulphur dioxide to produce an alkyl phosphonyl difluoride, or by reacting with water to produce an alkyl phosphonic acid.  Specified alkyl groups are methyl and ethyl.  In an example a mild steel autoclave is charged with (CH3.PCl3.AlCl4) complex and anhydrous hydrogen fluoride, the latter being contained in a suspended polythene bucket. The reactants are then mixed and allowed to stand at room temperature for several hours until the autoclave is quite cold. The gaseous contents of the autoclave comprising essentially methyl phosphorus tetrafluoride (CH3.PF4), hydrogen chloride, and excess hydrogen fluoride are then mixed with a stream of sulphur dioxide and the mixed gases passed through an iron tube containing stainless steel gauze and kept at 100 DEG  C. The off-gases are condensed in a copper pipe kept at about -75 DEG  C. to yield methyl phosphonyl difluoride (CH3POF2), the identity of which is checked by hydrolysing a sample with dilute hydrochloric acid to form methyl phosphonic acid.  The complex compound derived from methyl chloride can be produced in known manner by combining the three components in equimolecular proportions in an additive reaction.  The Provisional Specification refers to the use of a complex of an alkyl halide, phosphorus trichloride and aluminium chloride.
Patent GB-738441-A (GB)
Title: The stabilisation of hydrazine
IPC: C01B21/16
Filed: 1953-07-08
Abstract: Concentrated hydrazine, e.g. a hydrazine solution of a greater concentration than hydrazine hydrate up to substantially anhydrous hydrazine, is stabilized by the addition of magnesium, calcium, zinc or aluminium, or an oxide or carbonate of such metal.  0.2 to 5 per cent of zinc oxide may be employed.  The added metal, oxide, or carbonate neutralizes acidity in the hydrazine.  Any excess, which remains insoluble, may be readily removed by settling and decanting or by filtration, whereafter the hydrazine may be distilled.

Title: Improvements in the crimping of yarns
Inventor: WILLENS ROBERT ALFRED ARCHIBAL
IPC: D02G1/02
Filed: 1956-06-19
Abstract: <PICT:0848798/IV(a)/1> <PICT:0848798/IV(a)/2> In crimping yarn of staple fibres or continuous filaments of regenerated cellulose such as viscose, organic derivatives of cellulose such as cellulose acetate, or wholly synthetic materials such as polyhexamethylene adipamide, polyaminocaproic acid, polyaminotriazoles and polyethylene terephthalate, the yarn is drawn from source at one linear speed and forwarded at a higher linear speed to a zone (in which false-twist is imparted) so as to stretch the yarn by an extent which may exceed the elastic limit, immediately before it enters the zone.  The stretching, e.g. 3-7 1/2 %, or 600% if also used to develop physical properties such as tensile strength in a synthetic material, may be effected when the yarn is cold or softened, as by heat.  As shown in Fig. 1, yarn 5 from a package 6 passes through a guide 7, around two sets of stretching rollers 8, 9 and 11, 12, through a steam header 13 (which may be replaced by an electrically heated chamber) and a false-twisting device 17 and is wound, with controlled relaxation, into a package 22.  In a modification, Fig. 2, yarn passes in contact with a heated surface 25 and, optionally, around a snubbing pin 26 which may be rotated with a peripheral speed less than that of roller 8.  Two or more yarns may be stretched between rollers 8, 9 and 11, 12, combined with doubling twist in the false-twisting zone and then separately wound, Fig. 4 (not shown).

Title: Ethanol-miscible methyl phenyltertiarybutoxypolysiloxane
IPC: C08G77/00
Filed: 1955-07-01
Abstract: An ethanol-miscible organopolysiloxane, for use in various lotions and polishes in cosmetic and pharmaceutical preparations is made by hydrolysing a mixture consisting, by weight, of from 25 to 30 parts dimethyldichlorosilane, from 22 to 26 parts trimethylchlorosilane and from 45 to 50 parts phenyltrichlorosilane, using as the hydrolysing medium a mixture consisting, by weight, of from 90 to 110 parts tertiary butyl alcohol and from 200 to 400 parts water per 100 parts of the silane mixture, and isolating the water-insoluble methyl phenyltertiary-butoxypolysiloxane produced.  In the example the silane mixture was slowly added to the hydrolysing medium, the temperature being kept below 80 DEG  C.; the siloxane layer was then isolated and neutralized with sodium carbonate, filtered and dried, after which low-boiling polymers were removed by vacuum distillation. The product was an oil of 40 cs. (at  DEG  C.) viscosity and a molecular weight of about 700.  The products contain from 0.5 to 5 per cent by weight of siloxane of Si-bonded tertiary butoxy groups and exhibit unusual compatibility with mineral and castor oils, and a 5 per cent solution in ethanol can hold up to 14 per cent water in solution without any phase separation.ALSO:Ethanol miscible methylphenylpolysiloxanes (see Group IV (a)), which in the form of 5 per cent ethanol solutions can hold up to 14 per cent by weight of water without phase separation, are used in the preparation of cosmetic and pharmaceutical products, such as sun tan lotions and salves, and in the treatment of certain fungicidal infections such as athlete's foot.

Filed: 1956-06-21
Abstract: 810,505. Sound-absorbing media. WIEDERHOLD, W., [trading as KOMM.-GES. H. WIEDERHOLD.]. June 21, 1956 [June 21, 1955], No. 19315/56. Drawings to Specification. Class 40 (8). In a liquid filled acoustic measuring tank, the internal wall surfaces are rendered non-reflecting to sound waves in the liquid by a soundabsorbing coating. The coating consists of an elastic material, e.g. rubber or a thermoplastic polymeric substance and the acoustic losses within the elastic material are introduced by the dispersion of particles of an additive such as cork, cellular rubber or a plastic, or sand in the elastic material. The distribution of additive particles is such as to cause the losses to rise in the direction from the liquid to the tank wall. The elastic coating may have a smooth or an indented surface and the additive particles may be of a uniform size or may increase in size towards the tank surface.
