Abstract: 805,597. Band brakes. SELF-CHANGING GEARS Ltd. April 3, 1957 [April 12, 1956], No. 11126/56. Class 103 (1). [Also in Group XXIV] Relates to forward and reverse planetary gearing for rail-cars in which forward or reverse drives are obtained by application of separate band brakes (see Group XXIV). Each brake comprises an applying piston-rod 54 connected to one end 58 of a central, single band nearly circumscribing a brake drum 12 and attached at its other end 60 to a connecting link 62. On each side of the central band lie a pair of bands having their first ends 64 attached to the connecting link 62 and their other ends 67 attached to a reaction link 69. Small pads of friction material may be secured to the inside of the connecting link 62 to engage the brake drum 12. The piston actuation rod 54 is moved to apply the brake against the bias of a spring 53 when air under pressure is supplied to a space 75 at the front of the piston. A gear pump driven from the output shaft of the reverse gearing supplies oil under pressure to the space 47 at the back of the piston to prevent it applying the brake until movement in the opposite sense has ceased, viz. to prevent the reverse brake band being applied while the output shaft of the gear is still moving in the forward direction, and vice versa.

Title: Improvements in or relating to colour photography
IPC: G03C7/327
Filed: 1945-05-04
Abstract: Hydrophilic vegetable protein compounds contain a plurality of dye intermediate nuclei which contain a group capable of coupling with the oxidation products of an aromatic primary amino photographic developing agent to form an azomethine or quinone-imine dye.  The vegetable protein (zein, gliadin, hordein, wheator maize-gluten, oryzenin, edestin, phaseolin, wheat-globulin, ricin, leucosin, or legumelin, or derivatives such as piperidylmethylzein, dimethylaminomethylzein, or dimethylaminoethylzein) may be condensed with a bifunctional condensation agent (formaldehyde, formaldehyde-yielding material, dimethylolurea or its mono- or di-methyl or ethyl ethers, dimethyloladipamide, or dimethyloloxamide) and a dye intermediate either simultaneously or stepwise.  The reaction may be effected in the presence of a solvent or non-solvent for the protein, and condensation agents may be added.  The dye intermediate may contain a group readily eliminated in the coupling reactive position.  The change in water-solubility produced by the introduction of the dye intermediate groups may be balanced by selection of treatment of the proteins before or after condensation (e.g. by condensation with fatty acid chlorides such as acetyl, lauryl, or stearyl or with aromatic acyl halides, e.g. benzyl chloride), by selection of the bifunctional condensation agent (use of glyoxal, or of formaldehyde and hydroxyethanesulphonic acid or glycollic acid), or by selection of the dye intermediate group. Light-sensitive emulsions prepared using the protein derivatives as binders may contain sensitizing dyes, sodium thiosulphate or hyposulphite, allyl thiourea or isothiocyanate, benzimidazole, nitrobenzimidazole, benztriazole, methyl thiouracil, chrome or potassium alum, formalin, dimethylolurea, thymol, menthol, or alcohol.  Examples are given of the preparation of zein derivatives containing dye intermediate nuclei, e.g. from 1 - phenyl - 3 - methyl - 5 - pyrazolone, saligenin, or acetoacetanilide.  Specifications 484,698; 545,443, 545,444, [both in Group XX], and 11153/53 (as open to inspection under Sect. 91) are referred to.

Abstract: 561,550. Toothed gearing. RICHARDSONS, WESTGARTH, & CO., Ltd., SIGNER, J. U., PARSONS MARINE STEAM TURBINE CO., Ltd., and DOUGLAS, L. M. Aug. 19, 1942, No. 11674. [Class 80 (i)] Relates to gearing of the type in which a primary pinion drives two primary wheels each of which drives a secondary wheel through a secondary pinion. Such gearing is disclosed in Specifications 111,329, 116,531, 117,840, 120,257, 125,203, and 146,641, [all in Class 80 (i)], The invention is directed to means for automatically accommodating inaccuracies of the gear teeth. As applied to a turbine installation having an H.P. and L.P. turbine shaft coupled respectively to two double helical primary pinions, each such pinion a, a<1>, Figs. 1, 2, drives two primary wheels b, band b<1>, b<1> the shafts of which carry secondary pinions c, c, c<1>, c<1> engaging a common secondary wheel d. Each primary wheel is single helical and is driven by one helix only of the double primary pinion a or a<1>. The secondary gears are preferably double helical; but may be straight or single helical. The pinions a, a<1> have axial freedom obtained preferably by connecting them to their driving shafts through couplings permitting axial movement. The gear shafts each have two bearings. The secondary gears c, c<1>, d are disposed axially within the primary gears, and the secondary wheel d is preferably double helical with each secondary pinion axially free. To ensure that the turning forces on the two, secondary gears shall differ greatly,. the helical angle of the primary pinions is made small, e.g. 15 degrees, and that of the secondary gears large, e.g. 45' degrees. In a modification, in order that the turbines may be located nearer the gearcase, the two lower primary wheels are arranged at the end remote from the turbines. In both forms, the centres of the primary pinions a, a<1> and two of the four associated secondary pinions c, c<1> are disposed in the same horizontal plane, thus permitting the cover to have a plane horizontal joint.

Title: Improvements in viscosity flow control means
Inventor: HEITMANN ARNOLD MANDIUS
IPC: F02C7/224
Filed: 1966-03-17
Abstract: 1,090,494. Gas turbine engines. GENERAL ELECTRIC CO. March 17, 1966, No. 11710/66. Heading F1G. [Also in Division F2] To ensure the supply to a gas turbine engine of a sufficient amount of atomized fuel, particularly at starting, the reduction of the percentage of fuel which atomizes properly, normally occurring as the fuel viscosity increases, is compensated for by increasing the rate of fuel delivery to the engine as the viscosity increases. A viscosity-sensitive control 82, Fig. 4, for this purpose is connected in parallel with the main fuel metering valve and comprises a passageway through which laminar flow of fuel occurs. The pressure drop along the passageway, which is proportional to the product of the fuel viscosity and the rate of flow through the duct, is used to control the supply of fuel. The passageway may be straight but preferably comprises a helical tube 122, the pressure drop across the helical tube being applied to the opposite sides of a bellows 110 carrying a needle valve 116 co-operating with a thin plate orifice 118. The initial position of the needle valve 116 relative to the orifice 118 is adjustable by a nut 130. Fuel delivered by a pump to an inlet 96 flows through the orifice 118 and thence through the helical tube 122 to an outlet 98 leading to the burner nozzles. Any increase in fuel viscosity produces a proportionate increase in the pressure drop through the helical tube 122, causing the bellows 110 to move the needle valve 116 to the right to reduce the pressure drop through the orifice 118, thereby increasing the fuel flow. The viscosity-sensitive control 82 may be used to provide the entire supply of fuel at starting or may supplement the minimum flow provided by the main fuel metering valve of the engine. Preferably, a constant pressure drop is maintained either across the orifice 118 or across the entire control 82 by means of a pressure drop regulator of known type. In an alternative arrangement, the laminar-flow passageway (148), Fig. 5 (not shown) is connected in series with a sharp-edged orifice (152) of fixed area, the combination being connected in parallel with a sharpedged orifice (142) which is adjustable by a needle valve (144) carried by a bellows (146) subjected to the pressure drop through the passageway (148).
