Abstract: 880,734. Rotary motors. GENERAL GAS LIGHT CO. Nov. 5, 1959, No. 37541/59. Class 110 (2). Fluid, preferably air, under pressure is admitted successively to a number of stationary flexible tubes 32 which expand against rollers 24 and cause rotation of a rotor 25 and an output shaft 26. Fluid enters through inlets 14 and 18 in a rotary valve 16 to chambers 7, 8 leading to the tubes 32, and is discharged under control of a rotary valve 36 and ducts 40. Part of the exhaust passes through ports 44 in through the rotor for cooling purposes and leaves through ports 46. The supply of fluid may be varied by angular adjustment of a valve 5 as shown by a pointer 9, to vary the degree of opening between ports 6 and chambers 7. Flat support plates 33, projecting through the tubes, and carried by nipples 31, prevent angular displacement of the centre portions of the tubes. Fig. 7 shows a modified arrangement in which a carrier 48 is provided with flattened end studs 49 for connection with the inlet and outlet valves. The rolls 51 are mounted in recesses 50 which have an anti-friction lining 52, and the ends of the rollers are enlarged at 53.

Title: Improvements in or relating to incandescent gas lamps
IPC: F23D14/30
Filed: 1929-12-09
Abstract: 339,494. South Metropolitan Gas Co., and Chandler, D. Dec. 9, 1929. Street and like overhead lamps; lantern cowls. -In an incandescent gas lamp a superheater for the primary mixture of air and gas is of inverted cup shape and means are provided for directing the secondary air into the cup to be preheated before passing to the combustion zone. The superheater 1, Fig. 1, has internal vanes 5 to assist in heating the secondary air and external vanes 14 to take up heat from the products of combustion. Secondary air enters the bottom of a tube 6, supported by a spider 16 mounted on a rod 17 screwed into the superheater 1, and is directed into the inner surface of the superheater where it is warmed before passing to the combustion zone. The products of combustion pass between the superheater and the inner surface of a canopy 7 to a chimney 8. Primary air is supplied through holes 22 from a chamber 25. In a modification, Fig. 2, the gas supply pipe 24 passes up within the tube 6, the primary air being slightly heated before passing through the holes 23. A deflector 30 deflects the heated secondary air on to the tube 6 before passing to the combustion zone. To facilitate assembly and replacement of parts the tube 6, supported by flanges 32, supports a shield 29 flanged at 34 to carry a globe 18. The superheater, carrying the chimney 8 and canopy 7 is supported by the gas supply pipe 24, the upper and lower parts of which are connected by cone and socket joint 36. In the modification shown in Fig. 3 a cone plate 38 resting on a shoulder 40 on the tube 6 closes the cup-shaped superheater, the heated secondary air reaching the combustion zone through openings 39. The canopy 7 is hollow and filled with a. heat insulating material 41. In a further modification the heated secondary air passes to the combustion zone through a perforated block. In the form shown in Fig. 1, the outlets 9 of the chimney 8 are protected by two concentric shields 11 and 13 with apertures 10 and 12. The chamber 25 from which the primary air is supplied communicates with the atmosphere through openings 26 masked by a baffle plate 27.

Abstract: 1330745 Packages E I DU PONT DE NEMOURS & CO 11 Aug 1971 [12 Aug 1970 30 March 1971] 37780/71 Heading B8C [Also in Divisions B5 and C3] A sealed package containing a measured quantity of a powdered material is made of a plastic film which is readily soluble in cold water (see Divisions B5 and C3). Powdered materials which may be suitably so packaged include pesticides, e.g. the insecticide methomyl, fungicides, herbicides, foodstuffs and foodstuff additives. A package may comprise one or more such packages enclosed in a moistureproof over-wrapping. Such a composite package may contain one package containing the fungicide benomyl and one package containing the fungicide maneb. To minimise the possibility of packages made from the film becoming brittle on storage, the packages may be made and filled in an atmosphere above 35% relative humidity and immediately enclosed in a moisture-proof overwrap. Alternatively, excessive brittleness under low relative humidity conditions may be avoided by including small amounts of highly polar water-soluble substances such as dimethyl formamide, dimethyl acetamide, ethylene glycol, propylene glycol, glycerol or polyglycols as plasticisers in the film. Packages may be made from the films of the invention on commerically available plastic film package making machinery. In the laboratory bags may be made from the films of the invention by wetting a quarter inch band along three edges of a rectangular piece of the film, followed by placing a second piece of film of the same size as the first piece over the first piece and exerting mild pressure along the wetted edges. The resulting bag with three sealed edges may be filled with a powder and the fourth edge sealed similarly, or by heat-sealing at 120 to 140 C. A moisture-proof overwrap is provided to prevent damage from moisture.
