Title: Improvements in or relating to inlet valve operating gear for liquid piston internal combustion pumps & prime movers
IPC: F04B49/10
Filed: 1929-08-14
Abstract: 338,165. Christie, S. P. Aug. 14, 1929. Direct explosion apparatus.-In a liquid piston internal-combustion pump, a semi-rotary disc fuel inlet valve is arranged to be moved and controlled by a device operated by the flow of liquid or exhaust gases, or by pressure variations within the combustion chamber. The valve is described adapted to a pump working on the twostroke cycle. In Figs. 1 and 3, the compressed air and gas is led by pipes 11 and 12 to the valve chamber 13, which contains a ported disc 14 seated on a ported plate 15 on the other side of which seats a spring-loaded non-return valve 19. The valve spindle 16 has a crank 18 attached, carrying a spring 32 to bias the valve in the open position. The crank 18 is connected by the rods 31 to a paddle 30 situated in the play pipe which operates the valve in accordance with the cyclic flow of liquid. Fig. 4 shows a spring 36, connected to one end of the crank 18, which tends to open the valve, whilst a piston 34, operating in the cylinder 35 connected to the stand pipe, is connected to the other end. A cam 39 arranged on the valve spindle engages with a detent 40 operated by the paddle. During the return flow of the liquid the paddle lifts the detent and the valve is opened by the spring 36. During compression the movement of the piston 34 closes the valve and the discharge of liquid during the working stroke moves the paddle in the reverse direction and closes the detent 40. Various modifications for moving and locking the valve are described in which (a) the valve is inter-connected with the exhaust valve and locked by a detent operated by a paddle, (b) an electromagnetic relay is arranged between the paddle and the detent, (c) the valve is operated as in Fig. 4 and the detent operated in a similar way, (d) the detent is operated by an electromagnetic relay from a paddle situated in the exhaust flow. Specification 241,635 is referred to.

Abstract: 283,280. Aerozon Air Conditioning Co., Ltd., Lipscombe, H. W. J., and Whatton, F. Oct. 7, 1926. Air and gases, moistening.-In humidifiers in which the water is induced by air or gas under pressure, such as described in Specifications 220,703, 251,001, air is automatically admitted to the water line near to the atomizer soon after the water supply is shut off. Compressed air and water are supplied through hollow legs 2, 3, respectively of an atomizer 1. A tube 7 extending into the leg 3 is adjustably carried by a con. nector 8 which is screwed into a container 10 having air holes 14 and supplied with water from a pipe 13. The water level is normally maintained at the height A-A slightly above the lower end of the tube 7 by means such as a float chamber of small capacity. On the water supply being cut off the level within the container rapidly sinks to the mouth of the tube, the supply to the atomizer thereupon ceasing.

Abstract: 1,146,716. Magnetic structures. MAGNETICS Inc. 4 June, 1966, No. 24991/66. Heading H1H. A magnetic core is produced by annealing magnetic Mo-Ni-Fe alloy particles at a temperature of at least 800‹ C., rolling the particles to form flakes 20-25 Á thick and 250- 350 Á in diameter, reannealing in H 2  at a temperature of at least 800‹ C. while mixed with powdered mica to prevent agglomeration, applying a plurality of insulating coatings containing at least 50% mica having a particle size up to 90 Á, forming a core by pressing the coated particles in a die such that the flakes are parallel, and perpendicular to the axis of the core, and annealing at 800-1000‹ C. without breakdown of the insulation. During rolling, a paraffin oil lubricant may be used, which is removed with trichloroethylene. The insulation may be applied, e.g. in at least 4 coats, as a slurry of water, mica, Mg(OH) 2  and Na or K silicate, followed by drying in a rotating drum at 150- 160‹ C. and forced cooling to 80‹ C. The mica may be natural phologopite or muscovite, or synthetic mica. The die may be torroidal or non- torroidal and powdered magnetic material may be added on top of the flakes in the die to enable the edges of the final core to be rounded. After annealing, the core may be force cooled in H 2  or H 2 -N 2 , then reheated in air at 250‹ C, cooled in water and dried at 150‹ C., or mechanically vibrated at 60 cps., and coated with epoxy or enamel. The alloy may contain 2% Mo, 81% Ni, and 17% Fe. The core has a permeability of 550 at 10-100 g,. increasing to 600 at 1500 g.

Title: Improvements in sensitised photographic emulsions
IPC: G03C1/29
Filed: 1937-03-25
Abstract: 498,289. Sensitizing dyes for photographic emulsions. KODAK, Ltd. (Eastman Kodak Co.) March 25, 1937, No. 25050/38. Divided out of 498,031. Drawings to Specification. [Class .98 (ii)] Gelatino-silver halide emulsions contain a thiocarbocyanine or selenacarbocyanine and a dibenzthiocarbocyanine which combine to give a supersensitizing effect, i.e. a sensitivity greater than the sum of the sensitivities of the two dyes. The dyes may be included in the emulsion before coating or applied by bathing the coated emulsion. Examples of the sensitizers are : 2 : 2<1>-dimethyl-8-ethyl-thiocarbocyanine iodide ; 2 : 2<1> - diethyl - 8 - methyl - thiocarbocyanine iodide ; 2 :2<1> dimethyl - 8 - ethyl- 3 : 4 : 3<1> : 4<1>-dibenzthiocarbocyanine iodide ; 2 : 21 - di - ethyl - 8 - methyl - thiocarbocyanine iodide ; 2 : 2<1>- dimethyl - 5 : 5<1> : 8 -urethyl thio carbocyanine iodide ; 2 : 2<1> : 5:.5<1>: 8-pentaethylthiocarbocyanine iodide ; 4 : 4<1> - dichloro- 2 : 2<1> : 8-triethyl thiocarbocyanine chloride in conjunction with one of the following : 2 :2<1>- diethyl - 8 - methyl - 3 : 4 : 3<1> : 4<1> - dibenzthiocarbocyanine iodide ; 2 : 2<1> - dimethyl - 8 - ethyl- 3 : 4 : 3<1> : 41-dibenzthiocarbocyanine iodide or chloride and 2:2<1>:8-trimethyl-3:4:3<1>:4<1>- dibenzthiocarbocyanine iodide. The selenium containing carbocyanines are as effective as the thiocarbocyanines. The sensitizers may be included in the emulsions before coating or may be applied to the coated emulsion. The test to be applied in determining supersensitization is to compare the sensitizing effect of a mixture of equal quantities of the dyes with that of the same quantity of each individual dye. If it is greater than the sensitivity of each individual dye, then a supersensitizing combination is indicated. The Provisional Specification contains subject-matter which is described in Specifications 408,273, [Group IV], 498,031, 498,290, and 498,291.

Abstract: 626,072. Change-speed gear. BREGUET, L. Aug. 27, 1946, No. 25560. Convention date, Feb. 14, 1944. [Class 80 (ii)] [Also in Groups XXVI and XXVII] The invention includes a change-speed gear-box through which a centrifugal compresser is driven from the propeller shaft of an aircraft engine (see Group XXVII). A first-speed multiplicationgear may consist of a bevel pinion 4, Fig. 2, keyed to the propeller shaft 5, engaging a pinion 6 on the end of a transverse shaft 7 of the change-speed box 2. In the latter unit one or more gears are associated with the above multiplication gear and cause a driven shaft 8, Fig. 3, to rotate at the desired speed. The transverse shaft 7, which carries the gear wheels 22, 24 and a clutch unit, may drive either the gear wheel 22 through the agency of the roller 26 of a free wheel, when the clutch is disengaged, or the gear wheel 24 when the clutch is engaged. The clutch comprises a number of discs, 28a, 28b located inside a flanged hub 27 that is secured to the transverse shaft 7. Pivoted weights 29 under the action of centrifugal force, cause the clutch discs 28a, 28b to be subjected to axial thrust, thereby completing the coupling of the gear wheel 24 and the flanged hub 27. The pivoted weights 29, which are formed with projections, may be moved in the direction of the engine by a hand actuated sliding sleeve 30, through the operation of a rod 31 and jack 32 and so can disconnect the gear wheel 24 and the flanged hub 27, under which conditions the transverse shaft 7 drives through the gear wheel 22. The shaft 8, which carries the pinions 23, 25 that mesh with the gear wheels 22, 24 respectively, is coupled to the torsion shaft 10, through the medium of a centrifugally operated friction coupling 9 (see Group XXVI).
