Title: Improvements in or relating to rendering fabrics water-repellent
IPC: C08L83/04
Filed: 1950-09-06
Abstract: A composition for rendering fabrics water-repellent comprises a mixture of 20-70 per cent by weight of a methylpolysiloxane containing between 2 and 2.1 CH3 radicals per Si atom and with a viscosity of 1000 to 100,000 centistokes at 25 DEG  C., and 80-30 per cent of a methylhydrogenpolysiloxane containing between 1.0 and 1.5 CH3 radicals and between 0.75 and 1.25 hydrogen atoms bonded to silicon per Si atom, there being a total of 2 to 2.25 CH3 radicals and H atoms per Si atom in the methylhydrogen polysiloxane.  The mixtures may be subsequently polymerized with evolution of hydrogen by heating at 100 DEG  to 475 DEG  F. for 5 seconds to 1 hour. Catalysts which may be added to the mixture include sodium bicarbonate, sodium aluminate and iron, cobalt, manganese, lead and zinc salts of carboxylic acids such as acetates, octoates and naphthenates.  The composition may be diluted with a hydrocarbon, chlorohydrocarbon, ether or alcohol, e.g. benzene, dioxane or ethanol, or emulsified with water and an emulsifying agent decomposable by heat, e.g. trimethylbenzylammonium chloride and hexadecyldimethylbenzylammonium chloride, the above solvents being used, if desired to thin the emulsions.  An organic acid, e.g. acetic acid may be added to inhibit liberation of hydrogen. The liquid dimethylpolysiloxane, end blocked with trimethylsiloxy units, may be made by heating a mixture of decamethyltetrasiloxane, octamethylcyclotetrasiloxane and potassium hydroxide to 160 DEG  C., cooling to 100 DEG  C. and adding dry ice, with subsequent filtration and distillation under reduced pressure.  The other polysiloxane may be made by adding aqueous isopropanol to a benzene solution of CH3.H.Si Cl3, and (CH3)3SiCl, subsequent vacuum distillation yielding a trimethylsiloxy end-blocked methylhydrogenpolysiloxane.  Examples are given of various mixtures for rendering fabrics water-repellent. Specification 640,067 is referred to.

Title: Improvements in carburettors for internal combustion engines
IPC: F02M3/08
Filed: 1928-08-08
Abstract: 303,492. Seignol, E. Jan. 6, 1928, [Convention date]. Spray-carburettors.- A Venturi tube 1, to the interior of which fuel or rich mixture is supplied from an annular space 8 through apertures 9, is provided at its inlet end with an air-admission valve 2 mounted on a trunk of a piston 4 which is subjected on its lower face to the suction in the Venturi through a movable orifice 6 at the top of the trunk. The piston 4 is loaded by a spring 7 and moves in a cylinder 5 the upper end of which has an airescape orifice 14. The air supply to the Venturi is admitted through ports 11. When the throttle valve 12 is closed, the spring 7 forces up the valve 2 to obstruct the Venturi, and the engine is supplied through a valve-controlled bye-pass. If the valve 12 is opened to give a mean running speed, the suction in the Venturi has a mean value, and the valve 2 is lowered to a position somewhat as shown in the Figure. Thus the orifice 6 will be brought nearer the throat of the Venturi, but at the same time the passage around the valve 2 will be enlarged. Further opening of the valve 12 will result in the piston 4 and valve 2 being brought to their lowest position. If, with the valve 12 fully open, the engine has to meet an excessive load involving a decrease of speed, it is necessary to avoid choking the engine with excess of air and this is brought about by the combined effect of the decreased suction and the spring 7 which causes the valve 2 to move nearer its closed position but, owing to the shape of the valve 2, the air speed past the apertures remains high. The rich mixture supplied to the annular space 8 and to the bye-pass respectively may be formed in primary carburettors constituted by two Venturi tubes located on or near a fuel tank situated below and at some distance from the engine. The Venturis raise the fuel from a float chamber located at the bottom of the fuel tank, Fig. 4 (not shown). In a modification, the space 8 and the bye-pass are supplied with fuel through a calibrated orifice fed from a float chamber the level in which is maintained rigorously constant by the means described in Specification 284,226.
Patent GB-1354620-A (GB)
Title: Water degradable metal containing polymers from organic acids
IPC: C08G79/00
Filed: 1971-04-19
Abstract: 1354620 Pesticidal and pharmaceutical application of metal-containing polymers AUSTIN SCIENCE ASSOCIATES Inc 19 April 1971 [11 March 1970 21 Oct 1970] 23036/71 Headings A5B and A5E [Also in Divisions C1 and C3] Medicines, pesticides and herbicides comprise water-degradable, metal-containing polymers in which metal atoms are coordinated with bidentate carboxylic acid ligands, the atoms of the metal being in the polymer chain and linked to each other through the carboxyl groups. The polymers are obtained by reacting in a solvent a carboxylic acid with a soluble salt of the metal in the presence of an aldehyde. The metal may be calcium, magnesium, strontium, barium, radium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, zirconium, niobium, molybdenum, cadmium, tantalum, tungsten, platinum, mercury, tin, lead, antimony, and the rare earth metals e.g. thorium. The polymers degrade on contact with water. Heating the polymer increases the molecular weight and produces a polymer which degrades less readily. Polymers may be prepared in which either the metal or the carboxylic acid is an active material which is gradually released as the polymer contacts moisture, or the polymer may be used to encapsulate material which is gradually released. Herbicides, insecticides, nematocides, fungicides, rodenticides and defoliants may be prepared in both these ways. When the active material forms a part of the polymer it may be dissolved in a solvent and sprayed or the solution coated on or absorbed in granular material. If the polymer is dissolved first in a nonionic surfactant it may be dissolved in water for a short time without degradation to enable it to be sprayed. Medicines e.g. insulin and thyroid extracts, may be encapsulated in the polymer for controlled release in the body, or a medicine, e.g. a salicylic acid compound, may be used to prepare the polymer. Calcium salts and maleic acid may be used to prepare polymers for use in medicines. For topical application of medicines and insect repellants, calcium salts and citric acid may be used. In Examples polymers are prepared by reactions in which the metal salts are ferric nitrate, cupric nitrate, cobaltous chloride, nickel nitrate, titanic trichloride, ferric chloride, calcium chloride, and the carboxylic acids are 2,4-dichlorophenoxy acetic acid, 2-methyl-3,6-dichlorobenzoic acid, benzoic acid, 2-(2,4,5-trichlorophenoxy) propionic acid, 4-amino-3,5,6-trichloropicolinic acid, 2,4, 5-trichlorophenoxy acetic acid and maleic acid; cinnamic aldehyde and benzaldehyde are used to catalyze the reactions. The herbicidal effects of polymers prepared from ferric nitrate and salts of 2,4-dichlorophenoxy acetic acid, 2,4,5- trichlorophenoxy acetic acid and 4-amino-3, 5,6-trichloropicolinic acid, is described, the polymer being distributed as sprays of polymer dissolved in acetone and as coatings of polymer on inert granular material and on fertilizer pellets.

Title: Improvements in or relating to electric switches
IPC: H01H5/16
Filed: 1919-09-19
Abstract: 154,022. Crompton & Co., and Jones, W. F. Sept. 19, 1919. Switches, quick-action.-In a switch in which the switch handle spindle carries integrally an auxiliary lever operated through a spring by a handle loosely mounted on the spindle, the movements of the lever are controlled by one or more spring-controlled detents mounted on the switch box, each detent having an eccentric cam-surface over which a pin on the handle rides towards the end of its traverse, thus allowing the spring to turn the lever and spindle to close or open the switch. The parts are shown in the " off " and " on " positions in Figs. 1 and 2 respectively. The handle E, loose on the switch spindle B, carries a pin F engaging the spring D which is also engaged by a pin C on the auxiliary lever A, shown in Fig. 4, the spring ends being crossed so that the spring is wound up by movement of the handle in either direction. The spring-controlled detent G, pivoted on the casing at M, holds the lever in the " off " position while the handle is moved until its tail 0 is depressed by a pin N on the handle, whereupon the lever springs over and closes the switch. Complete closure is ensured by the engagement on a lug U of a spring- pressed pawl P carried by the handle and prevented by a pin R fixed in the casing from engaging the lug until the handle has been thrown well over. Opening of the switch is assisted by the pressure on the lever at A<1> of a pin V carried by the handle, the action being completed by the spring. A second detent operated by the handle similarly to the detent G mav be used to prevent the switch from opening until the handle has made a predetermined reverse movement, should the grip of the switch blades be insufficient for this.

Title: Improvements in or relating to applying an adhesive tape band to an article
IPC: B65B67/06
Filed: 1957-07-22
Abstract: 863,031. Packaging-machines. KRUEGER, T. H. July 23, 1957 [July 23, 1956], No. 23169/57. Class 94(1). In a device for applying adhesive tape to the twisted neck of a bag or to bundles of pencils, &c. in which the article is passed into a channel in a frame, the tape lying across the mouth of the channel, actuation of a tape applying member by the entering article causes release of latch means with consequent operation of a tape severing knife. The frame, which may be mounted adjustably on a vertical standard 16, supports a roll of tape 28 which passes across the.mouth of a channel 32, its end adhering to frame portions 42, 44. The article is passed into the channel to carry the tape into a recess 50 in the tape applying member 54. Movement of the article along the channel rotates the member 54 about its pivot 56 against a spring 80 and the rear wall of the recess 50 presses the tape portions behind the article against a resilient projection 60 on the frame. A knife 62 is mounted on an element 66 pivoted to member 52 at 68 and biassed rearwardly by a spring 110. Near the end of its travel, the member 54 contacts a roller 108 to rotate a latch 96 releasing an element 74 pivoted at 76. The spring 80 causes rapid movement of the member 74 so that a roller 72 strikes an anvil 70 of the element 66 causing the knife 62 to be projected forward to cut the tape. The article may now be removed downwards through the portion 36 of the channel. Final movement of the member 54 also causea a resilient block 120 to press the tape against the franc portion 44 while a strip 122 on the knife presses its cut end against the portion 46. The spring 80 restores the parts to their initial position.
