IPC: F23D11/44
Abstract: 135,846. Gross, M. Sept. 5, 1916, [Convention date]. Vaporizing-apparatus.-A coal oil burner comprises diverging tubes 6 leading from a coupling 5 on the feed pipe 1 to a vaporizing.coil 7, the central portion of which is bent to form a U- shaped hanger 8 fitted with a nozzle 9. A plate 13 formed with concentric upstanding flanges 14, 15 and depressed portions 24 fits closely against and is soldered to the vaporizing-coil 7. The vapour issuing from the nozzle 9 mixes with air in a tube 20 carried by the plate 13 and passes between a removable cap 21 on the flange 15 and a spreader 23 secured to the tube 20 to burner apertures 16 in the flange 15. A starting- cup 10 is secured between the coupling 5 and a nut 12 on the pipe 1. The plate 13 is provided between the flanges 14, 15 and in the depressed portions 24 with drain-holes formed by striking downwards lips 18 from the plate. The drainholes lead to the cup 10. The feed pipe is controlled by a valve 2 and is connected to a pressure tank 4.

Abstract: 1,124,867. Friction clutches; reverse gear. TWIN DISC Inc. 23 March, 1967 [31 March, 1966], No. 13736/67. Headings F2C and F2D. A multiplate clutch in series with a cone clutch comprises interleaved friction discs 22, 23 respectively splined to an output hub 11 and to an axially slidable two-part intermediate member 13, 14 which has oppositely inclined conical surfaces 17, 18 engageable between driving cones 9, 8. A spring 26 normally separates the two parts 13, 14 of the intermediate member to disengage the multiplate clutch and a spring 25 separates the conical surfaces 9, 18. The clutch is engaged by supplying pressure fluid to a chamber 2, whereupon a piston 3 fast with the clutch cone 8 moves right to engage the clutch. The spring 25 may be stronger than the spring 26 so that, after initial engagement between the conical clutch surfaces 8, 17, the multiplate clutch is engaged before the conical surfaces 9, 18 or the spring 26 may be stronger than the spring 25 so that the conical surfaces 9, 18 are engaged prior to the multiplate clutch. The clutch may form part of a double clutch for a reverse gear (Fig. 2, not shown) in which one clutch (C3) directly connects the input and output shafts (5, 10) whilst the other clutch (C4) connects the input shaft (5) to the output shaft (10) through a countershaft reversing train (16c ... 16h). The clutch plates may be immersed in lubricating oil which is fed to a chamber (P) formed by one part (13) of the intermediate member and a radial disc (30).

Title: Improvements in the processing of photographic materials
IPC: G03C1/485
Filed: 1950-06-01
Abstract: 693,632. Processing photographic materials. KODAK, Ltd. June 1, 1950 [June 1, 1949], No. 13762/50. Addition to 631,184. Class 98 (ii). A rapid process for the formation of an image in a photographic emulsion layer comprises exposing imagewise a silver halide emulsion layer containing a developing agent, developing a silver image therein by treatment with an alkaline solution, stabilizing the layer by treatment with a solution of an alkali metal or ammonium thiocyanate or thiosulphate or of a thiourea or thioglycollic acid, and drying without further treatment. The developing agent is preferably a water-insoluble compound, e.g. 2: 3-, 2: 5-, or 3: 4-dihydroxydiphenyl or 5:6:7:8 - tetrahydronaphthohydroquinone, or may be water-soluble such as hydroquinone, pyrocatechol, or p -methylaminophenol sulphate. The emulsion should be well-hardened. The emulsion binder may be gelatine, polyvinyl alcohol, partially hydrolised polyvinyl ester, or cellulose ester. The stabilizing bath is preferably acid to neutralize the alkali of the developing solution. The alkaline solution may be applied by wiping the surface of the emulsion with a sponge, rubber roll, or other applicator wet with such solution, or the exposed layer may be pressed against a pad moistened with the alkaline solution. In example (1), aqueous solutions of silver nitrate and of sodium chloride are simultaneously run into aqueous gelatine solution while stirring, aqueous gelatine solution, methanol 3: 4-dihydroxyphenyl solution, and formaldehyde or other hardener are successively added, and the emulsion is coated on paper. After exposure, the material is treated in an aqueous solution of sodium carbonate, hydroxide, and thiosulphate, and potassium bromide to effect development, either by applying such solution by a sponge or by moistening a pad of cloth, paper, felt, sponge rubber, or water-permeable hydrophilic colloid (e.g. gelatin, gum arabic, or polyvinyl alcohol hardened with melamine-formaldehyde condensation product) and pressing the exposed layer thereagainst, and is similarly treated with an aqueous stabilizing solution of sodium sulphite, bisulphite, and thiosulphate. In example (2), aqueous silver nitrate and potassium bromide solutions are successively run into a gelatine solution, further gelatine solution and a surface-active agent are added, the pH is adjusted to 5.0, a methanol solution of 3: 4- dihydroxydiphenyl and formaldehyde are successively added, and the emulsion is coated on paper. The further procedure is as in example (1). The emulsion may also be a direct-positive type of emulsion such as is described in Specification 667,206.

Title: Improvements in or relating to liquid fuel burners
IPC: F23D11/24
Filed: 1946-05-10
Abstract: 611,843. Fluid-actuated valves. LANGHAM. A. J. May 10, 1946, No. 14171. [Class 135] [Also in Group XI] In a liquid fuel burner in which preheated fuel is supplied under pressure to a nozzle 8, an automatic cut-off valve 9 is controlled by a piston 17 working in a cylinder 16 connected to the valve chamber 6 by an integral or screwthreadedly connected tube 15 which does not form part of the hot oil supply channel. The piston 17 is coupled to the valve 9 by a rod 14, a spring 18 being provided to urge the piston to close the valve while a light spring 11 on the valve 9 opens the valve when the pressure of the fuel has caused the piston to slide back in its cylinder, the rod 14 being preferably of non-circular cross-section to allow fuel to enter the chamber to act on the piston which may be provided with a synthetic rubber self-sealing washer 20. The rod 14 may be connected directly to the piston or may abut against a spring-urged sleeve 25 having slots 28 for projections 27 of a stem 24 connected to the piston 17 so that when the fuel pressure drives back the piston, the end 22 of an axial stem 21 opens an air valve 29 and operates any electric control switches provided before the valve 9 is opened, by reason of the lost motion permitted by the slots 28. The tension of the spring 26 urging the sleeve 25 may be adjusted by rotation of the end 22 so that the stem 24 rotates the screw-threaded member 26 against which the spring abuts. The amount of the stem 21 which projects from the cylinder serves as a visual indication of the adjustment of the valve 9, and if the end 22 of the stem 5 is not used to operate an air valve or electric control, it may be covered by a removable cap screwing on to the cylinder.

Filed: 1967-03-29
Abstract: Micron-sized particles are reduced by partially filling a baffle-free, agitator-free, smooth-inner-surfaced cylindrical drum with a fluid suspension of particles, liquid and particulate grinding medium of size - 4+35 mesh.  There is sufficient liquid to form a slip.  The drum is continuously rotated about its horizontal axis at less than critical speed, so that the suspension occupies only the lower portion of the drum.  The individual particles of grinding medium travel in continuous generally elliptical paths within the suspension.  The density of the grinding medium is greater than that of the particles to be ground, and may comprise 1/32 inch steel balls or shot. Materials to be ground include calcined kaolin clay, limestone, talc, with additives, e.g. sodium silicate, and to reduce iron pick-up by the clay a high pH solution is used.  This may include tetrasodium pyrophosphate, soda ash, sodium hydroxide.ALSO:Micron sized particles are reduced by partially filling a baffle-free, agitator-free, smooth-inner-surfaced cylindrical drum with a fluid suspension of particles, liquid and particulate grinding medium of size - 4 + 35 mesh.
