Title: Improvements in or relating to photographic materials
IPC: G03C1/79
Filed: 1943-10-15
Abstract: Photographic printing paper comprises paper carrying surface coatings of hydrophobic polyvinyl acetal resin and carrying at least one emulsion layer, which may be separated from the resin layer by a colloid layer strongly adherent to both.  The resin may be obtained from polyvinyl acetate by partial or complete hydrolysis with simultaneous or subsequent reaction with formaldehyde, or a higher aldehyde.  A solvent of the resin in a preferably volatile organic solvent or solvent mixture is applied to one or both sides of paper base.  A subbing layer containing cellulose nitrate and gelatin, or successive layers of cellulose nitrate and gelatin, is then applied. The first subbing solution should preferably contain a substance having a slight solvent action on the resin.  In an example, paper base is successively coated on opposite sides with a solution comprising "Formvar" (Registered Trade Mark) 15-95, benzene, and ethyl alcohol, then on one side with a layer of nitrocellulose, with a gelatin layer, and finally with a gelatin silver halide emulsion layer.  The resin solvent may alternatively be a chlorinated hydrocarbon; dioxane; acetic acid mixtures of ethyl alcohol with toluene, xylene, monochlorobenzene, or carbon tetrachloride; or a mixture of ethylene dichloride and methyl alcohol.  A plasticizer such as benzyl benzoate, tricresyl phosphate, p-tert.-amylphenol, dibutyl phthalate, or tributyl phosphate or mixtures thereof may be added.  The paper base may carry a baryta coating immediately adherent thereto.
Patent GB-625244-A (GB)
Title: Improvements in power transmission systems particularly applicable to gun mountings
IPC: F41A27/26
Filed: 1939-06-09
Abstract: 625,244. Fluid-pressure servomotor-control systems. VICKERS-ARMSTRONGS, Ltd., and CLARKE, T. F., and COLE, P. W., [Representatives of INGOLDBY, M. K.], SPAINK, J. H. ABBINK-, and SPENCER, A. June 9, 1939, No. 16963. [Class 135] A power transmission system, particularly for gun mountings, includes a hydraulic power amplifier unit, Fig. 1, whose sensitive control element 4 is driven by an electric motor, means being provided in association with the hunter control element of the unit for limiting its rate of displacement in either direction. The element 4 drives, through a shaft 5, a side member 3 of a differential whose centre member 2 drives a shaft 8. This shaft 8 is threaded to engage a fixed nut 10 and thus when rotated is also translated to control a valve 1 regulating the supply of pressure fluid from an inlet 16 to the cylinders 17. The resultant rotation of the angle box 18 drives an output shaft 11 at high speed, this shaft being connected to a shaft 12 which leads back to the differential in such manner that the member 2 has a displacement proportional to the speed of shaft 11 and also to the lag in the amplifier. As shown in Fig. 3, such displacement causes a corresponding displacement of a piston 22 working in a fluidfilled cylinder 23. The ends of the cylinder are interconnected by two passages 24, each fitted with a non-return valve 25, a needle valve 29, and a valve 26 which has a bore shaped as shown and which is rotated by a pin 28 on a rack 21 driven by the member 2. The two passages have their valves 25 and also the valves 29 oppositely arranged with respect to the cylinder, and the ports in valves 26 are also oppositely arranged so that when one valve is closing the other valve remains open for a time. A bleed hole 30 is formed in the piston 22. In use, fluid passes through one or the other of the passages 24 when the piston moves to the right or left of its central position, but at higher speeds of the amplifier both valves 26 become closed and the speed of the piston is thereby reduced. Thus the rate of displacement of the valves of the hunter gear is limited so that the acceleration of the output is controlled. Lag correction may be introduced, Fig. 4 (not shown), by a further differential between the follow-up motor and the spindle 4.

Title: Multi-pass, reverse re-entry gas turbines
IPC: F01D11/02
Filed: 1967-04-13
Abstract: 1,119,287. Turbines; jet propulsion plant. GENERAL MOTORS CORP. April 13, 1967 [Aug. 3, 1966], No. 17012/67. Headings F1J and F1T. An axial-flow gas turbine of the type having repeated action on a single rotor blade ring comprises a generally annular casing having a forward and a rear section and forming circumferentiallyspaced axial passes through the casing, forward and rearward passes alternating circumferentially of the casing, each pass comprising an inlet in one section and an outlet in the other section, the passes increasing in circumferential extent from high to low pressure; a turbine wheel coaxial with the casing comprising a shrouded ring of blades extending radially from a disc and rotatable successively through the passes; a set of nozzle vanes in each inlet; a recurved conduit connecting each outlet (except the last one) with the succeeding inlet; seals to oppose flow between the passes bypassing the blades and nozzles; and seal rings co-operating with the blade tip shroud ring and the disc and retaining the nozzle vanes and the seals in position. In the gas turbine shown in Fig. 4 and in developed view in Fig. 3, the gas passes through an inlet 35, first-stage nozzle vanes 62 and rotor blades 29 to the first-stage outlet 39, and thence through a recurved conduit 41 to the second-stage inlet 42. After passing through secondstage nozzle vanes 43, the gas passes again through the rotor blades 29 to a second-stage outlet 45 and thence through a further recurved conduit 46 to the third-stage inlet and so on. This circumferential dimension of the flow path increases from stage to stage. After passing through the ninth recurved conduit 53, the gas passes through a final set of nozzle vanes 55 to traverse the rotar blades 29 for the tenth time and then enters an exhaust collector 57 leading to three exhaust outlets (58, 59, 60), Fig. 2 (not shown) which discharge in a radially outward direction. Sealing between stages and particularly between the first and final stages is provided by shroud segments such as 68, 71 and also by annular seal strips 83, 84, 86, 88, preferably of an abradable honeycomb or cellular material, which co-operate with labyrinth ridges on the side faces of the rotor wheel 14. The annular seal strips are brazed or otherwise fixed to rings 74, 75, 91, 92 which also serve to retain the nozzle vanes and shroud segments in position. The rings 74, 75 are in turn located by a ring 77 while the rings 91, 92 may be bolted in place. The turbine may be incorporated in a jet-propulsion engine and drive a compressor supplying air to an annular passage (9).

Title: Methods and apparatus for the liquid treatment of filamentary material
IPC: D01D10/04
Filed: 1944-09-13
Abstract: <PICT:0583990/IV/1> <PICT:0583990/IV/2> <PICT:0583990/IV/3> Filaments and yarns are processed by applying a liquid to the materials and passing them in continuous length through a plurality of turns in a helical path at sufficient velocity to throw off the liquid by centrifugal force.  The process may be applied to a treatment comprising a plurality of stages, and between at least some of the stages the filament is caused to follow a helical path at sufficient velocity to throw off the liquid by centrifugal force.  In one form, the filament is treated with a liquid whilst passing through a plurality of turns in a helical path at a velocity insufficient to throw off the liquid by centrifugal force, and is then passed through a plurality of turns in another helical path at sufficient velocity to throw off the liquid.  In Fig. 4 (part) and Fig. 5 (part), the filament passes in a helix around roller 2a whilst liquid is applied by the means 3a.  The peripheral speed of the roller is insufficient to cause the liquid to be thrown off by centrifugal force.  The filament then advances to the roller 5a which is sufficiently smaller in size to cause the liquid to be thrown off.  The liquid thrown off is caught by the guard 4a.  Another liquid is then applied to the filament as it passes around roller 2b and is thrown off as it passes around the following roller 5b.  Conventional types of rollers may be used for advancing the filament in helical turns. In Fig. 3, the filaments are passed firstly over a larger roller 9 to which liquid is applied by the device 19, and then over a smaller roller 12 rotating at a higher angular velocity, but with the same peripheral speed.  The process may be applied to the treatment of freshly-spun artificial filaments from viscose, cuprammonium cellulose, cellulose acetate, proteins and the like; for example, in the case of viscose, separate rollers may be employed for washing, desulphurizing, re-washing, bleaching, anti-chlor treatment, washing and finishing.
