Title: Improvements in or relating to multi-layer photographic material
IPC: G03C7/20
Filed: 1945-03-22
Abstract: 589,507. Colour photography. COOTE, J. H., and AUSTIN, A. ST. J. March 22, 1945, No. 7265. [Class 98 (ii)] A multi-layer colour photographic material in which at least two silver halide emulsion layers sensitized to different parts of the spectrum are carried on the same side of a support, has an interposed regenerated cellulose layer united at its inner surface to the underlying emulsion layer by means of a bond comprising a hydrophilic polyvinyl compound, the adhesive power of which is sufficiently reduced when the material is permeated by an aqueous liquid to enable the regenerated cellulose layer, carrying the outer emulsion layer, to be separated from the underlying emulsion layer. The bond is formed by application, to the emulsion layer, of a solution of polyvinyl alcohol, partially hydrolysed polyvinyl acetate, or the latter material in conjunction with polyvinyl acetate, in a solvent medium which contains insufficient water to have appreciable swelling action on the regenerated cellulose film which forms the next layer, applying this regenerated cellulose film, pressing the layers together and drying. The exposed surface of regenerated cellulose may be sprayed with an aqueous gelatinchrome alum solution and dried before the overlying, silver halide emulsion is applied to it. A photographic material with three emulsion layers may be formed with a weaker polyvinyl bond between the outer emulsion layers than that between the inner emulsion layers so that the outer emulsion, with its regenerated cellulose support, may be readily separated from the remaining material on the application of water. Specification 564,976 is referred to.

IPC: F01L13/00
Filed: 1963-02-26
Abstract: 999,563. Reverse control. ARMSTRONG PATENTS CO. Ltd. Feb. 20, 1964 [Feb. 26, 1963], No. 7575/63. Heading F2D. A combined engine-throttle and reverse gear control for a marine I.C. engine comprises slave pistons 33, 36 for the gear 34 and throttle 37 respectively, actuated by liquid displaced through flexible pipes 6, 9 by master pistons controlled by a manual lever 25 movable in two planes in an E-shaped gate slot 50-53, movement in the longitudinal branch 50 of which turns a sleeve 13 carrying a two-lobed face cam 14 actuating two spring-loaded master pistons 17, 18 controlling displacement of the doubleacting reverse-gear slave piston 33, whilst movement in the transverse branches 51, 53, possible only in gear and neutral positions, advances a master piston 23 displacing the single-acting spring-returned throttle piston 36. The longitudinal gate slot 50 is V-shaped to produce a slight engine speed increase above idle on moving from neutral to either gear position to prevent stalling. The lobes of the cam 14 are of different heights to compensate for the volume of the gear piston-rod 33, and the lobes have setting notches corresponding to the gear positions. The throttle piston 23 is connected to the manual control lever 25 by a pin 21 solid therewith and slidable in slots 20 in side plates 19 welded to or cast integral with the rotatable sleeve 13. The lower end of the control lever 25 has a slot 27 engaging a fixed pin 22 in the side plates 19.

Title: Improvements in or relating to parachute-releasing mechanism
Inventor: HATFIELD JOHN EDWARD
IPC: B64D17/56
Filed: 1950-03-27
Abstract: 690,998. Parachutes. IRVING AIR CHUTE OF GREAT BRITAIN. Ltd. March 13. 1951. [March 27, 1950] No. 7621/50. Class 4. Parachute release mechanism comprises a spring-actuated mechanism in combination with means for controlling the freeing of the spring- actuated mechanism for movement to a parachute-releasing condition, such means being themselves driven in a releasing direction by the spring-actuated mechanism and associated with subsidiary control means consisting of or including a barometrically controlled device. As shown the rip-cord 7 is attached to a plunger 27 loaded by a compression spring 28, a peripheral groove 29 in the plunger engaging a pawl 31 carried by a lever 32 pivoting about a pin 33. The upper end of the lever 32 carries a pin 35 engaging a pin 36 in the spindle 37 of a toothed sector 38, forming the first member of a time-delay gear train 41, 43, 44, 45, the latter member of which gears with a pinion 46, Fig. 3, (not shown) driving an eccentric 48 engaging a forked element 49 secured to an oscillating governor disc 50. The time-delay mechanism may be prevented from operating by obstructing a pin 53 on the pinion 44 by means of a pin 55 operated by a barometric capsule to prevent opening of the parachute above a predetermined height, or by a spring 54, the end of which may be moved into the path of the pin 53. During normal automatic operation the end of the spring 54 is first withdrawn from the path of the pin 53 by the removal of an arming pin by a static or manually-operated line, and if the jump is made at a sufficiently low height the pin 55 is clear of the pin 53 to allow operation of the gear train, but if made at a great height the train is prevented from operating until the barometric capsule withdraws the stop pin 55 when the predetermined operating height is reached. When the gear train is freed the spring 28 forces the plunger 27 to the right, thereby moving the pawl 31 upwards and rotating the lever 32 clockwise to initiate rotation of the train. At the end of the delay period the pawl 31 moves clear of the plunger 27 and the spring 28 operates the rip cord 7. In an emergency, such as in the event of failure of the automatic control, the cord 7 may be operated by a rip ring on the wearer's harness. In an alternative arrangement, Figs. 6-8 (not shown), the arming pin for the spring 54 is withdrawn by a pilot parachute. Specification 601,829 is referred to.

Title: Improvements in carburetters
IPC: F02M15/02
Filed: 1921-03-10
Abstract: 185,438. Vernon, D. S. March 10, 1921. Vaporizers, external.-The fuel both for the main charge and for the starting or slow running charge for an internal combustion engine is passed through separate initially adjusted apertures and heated under engine suction to vaporize the fuel which issues through separate sets of annularly arranged apertures in the choke tube where it is mixed with air, the apertures for the main charge being controlled by a throttle valve but those for the starting fuel being uncontrolled. Fig. 1 shows a section through the apparatus, a heating chamber c being clamped between a floatchamber a and the carburettor b. The float-chamber has a well d<2> into which dips a tube having a fine bore e<1>, the fuel for the main charge passing up the annular passage around the tube and being atomized at a valve seating f<1> controlled by a screwed valve f, and that for the staring charge passing up the bore e<1> past a control valve g. The main fuel charge then passes through a coiled pipe h heated by exhaust gases entering the chamber c at c<2>, and the vapour enters an annular passage h<1> in the choke tube and issues through apertures b<2> in the lower inclined face b<4> of the choke. The apertures b<2> are controlled by a valve i having a face i<1> inclined similarly to the face b<4>, the valve i also controlling air inlet ports i<2>. The valve i is normally held closed by a spring i<3> and is actuated by a connection to its stem at i<5>. The slow running fuel charge passes through a tube j electrically heated by an insulated wire k, and the vapour enters an annular passage j<1> and issues through apertures b<3> in an upper inclined face of the choke. Air for the starting charge enters through a passage j<2> in the stem of the throttle valve and through a port j<3> controlled by a screw j<4>. The heating current may be cut off manually or automatically as the engine picks up speed. The air for the slow running charge may be heated electrically or by the exhaust and may enter the carburettor at all engine speeds. Instead of or in addition to the heating chamber c there may be a heating coil about the throttle apertures, or about the atomizing apertures, or iu both positions.

Abstract: 715,615. Electrode boilers. BATES, E. B. July 7, 1952 [April 5, 1951], No. 7871/51. Class 39 (3) An electrode boiler is gravity fed and the capacity of that part of the boiler which lies between the steam outlet and the lower end of the effective length of the electrodes is not greater than, and is preferably less than, the capacity of that part which lies between the inlet and the lower end of the effective length of the electrodes. Electrodes 23 are mounted in insulating bushes on a plate 25 at equally spaced intervals around the axis of a boiler 10 and have stems 24 surrounded by anti-flashover insulating sleeves 26 which space the exposed parts of the electrodes from the plate 25. A water inlet 12 is fed from a heater tank and a steam outlet 21 has shut-off and control valves 22, 29. Three phase current supply is indicated by an ammeter 18 and indicator lamps 19, and consumption is automatically controlled by the steam pressure which determines the extent to which the electrodes are immersed. The steam pressure is controlled by the head of the water feed. When using very hard water in the boiler, the electrodes may be supported on insulating rods or sleeves extending up from the bottom of the boiler so that the insulating bushes and at least the major portions of the sleeves are always immersed, thus preventing the formation of crystalline salts and precluding flashover.
