IPC: F23D11/10
Abstract: 117,618. Birkedal, H. A., and Nielsen, A. April 24, 1917, [Convention date]. Freely-flowing materials mixed in conduits.- Relates to apparatus for atomizing oil or 'the like in air in which the oil and air meet one another in co-axial and conical jets forced out from two co-axial chambers. The apparatus is of the kind having an adjustable fuel nozzle of diverging conical formation and an adjustable air or fluid outlet nozzle of converging conical formation disposed relatively in such manner that the air jet intersects the fuel jet immediately in front of the two nozzles. According to the invention, the width of the annular opening of the fuel nozzle increases in the outward direction in order to facilitate the passage of solid impurities. As shown, air and oil are supplied by pipes 1, 2 to co-axial chambers 3, 4 separated by a wall 5, which terminates at the outlet end in an outwardly-expanding conical opening fitted with a conical valve 8. The valve is of greater taper than its seat, so that the diameter of the annular space between the valve of the wall 5 increases in the outward direction, and the valve is adjustable by means of a hand-wheel 10 on its stem 9. A sleeve 11, adjustable on the outlet end of the outer wall 7 by means of a hand-wheel 12, has a narrow conical surface 15 corresponding to a similar surface on the inner wall 5. The substances to be mixed pass through the passages between the valve 8 and the wall 5 and the sleeve 11 and the wall 5. Instead of a movable sleeve 11, the sleeve may be integral with the wall 7, which may be movable around and on the inner wall 5.

Title: Improvements in means of conditioning air for dehydrating purposes, especially for withering tea leaf
IPC: F26B21/08
Filed: 1932-04-26
Abstract: 385,180. Conditioning air for drying. STROMGREN, S. and ALLM€NNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. April 26, 1932, No. 11968. [Class 34 (i).] Air for tea-withering or other purposes is dehumidified by passing it through a space which has cold and warm surfaces opposite each other. The cold surfaces should have a temperature appreciably lower than the desired dew-point of the conditioned air, while the temperature of the warm ones generally need not exceed that of the surrounding air. For example, air is drawn through wide pipes 7 surrounding vertical pipes 6 through which passes cooling fluid. Condensed water is drawn off through the pipe 11, and the air passes out through the tube 12.
Patent GB-1106082-A (GB)
Title: An improved method of and means of handling particulate material such as dust
Inventor: CONRAD STANLEY
IPC: B65G53/06
Filed: 1964-03-20
Abstract: 1,106,082. Pneumatic conveyers. BABCOCK & WILCOX Ltd. 22 March, 1965 [20 March, 1964], No. 12026/64. Heading B8A. An apparatus for discharging dust from a container 1 into a line 8 leading to a dust separator and slurry forming apparatus comprises coaxial pressurized air nozzles 10, 11 discharging into the line 8 at the base of the container 1 under the control of pneumatic valves 14, 15, nozzles 17 for discharging pressurized air into the chamber 1 under control of a pneumatic valve 20 and a pneumatically controlled sliding flap 27 controlling the flow of dust from a hopper 21 into the container 1. The flap 27 and valves 14, 20 together with a valve 30 controlling a dust agitating air nozzle 29 in the hopper 21, are connected into a common pneumatic system 33, 34 under the control of a timer 31 for cyclic operation. The valve 15 controlling the overall air flow is operated by an independent pneumatic system 39, 40 responsive to the level of dust in the hopper 21. In operation with the flap 27 open, valves 30 and 14 open and valve 20 shut, the dust gravitates into the line 8 where it is fluidized by air from nozzles 10 and 11, and the dust level in the container 1 steadily rises. At a predetermined time interval the timer 31 causes closure of flap 27 and valves 14 and 30 and opening of valve 20 whereupon the space above the-dust in the container 1 is pressurized to aid discharge therefrom, the discharged dust being fluidized by air issuing from nozzle 11 only. This cycle is then repeated. A safety valve 43 in the container operates in the event of a dust blockage and a pressure gauge may be incorporated to give warning and/or shut off valve 15 prior to the valve 43 operating. In a modification, a dust level indicator 44 in the container 1 causes the flap 27 and valves 14 and 30 to re-open, and valve 20 to re-close when the dust level drops sufficiently. In another modification the flap and valves are controlled by a pressure gauge 45 in the line 8 instead of by the timer 31. In the embodiment, Fig. 2 (not shown), the sliding flap is replaced by a pivoted flap controlled by the air pressure in the container.
Patent GB-552132-A (GB)
Title: Improvements in the production of pattern effects on cellulose derivative fabrics
IPC: D06Q1/02
Filed: 1941-09-19
Abstract: 552,132. Treating cellulose derivative fabrics with liquids. BRITISH CELANESE, Ltd. Sept. 19, 1941, No. 12082. Convention date, May 15. [Classes 2 (ii) and 15 (ii)] A fabric containing yarns of an organic derivative of cellulose, which are locally coated with a water-soluble resist comprising polyvinyl alcohol, is treated with a volatile non-aqueous shrinking agent which is a non-solvent for the resist so as to shrink the uncoated portions of the yarns. Local coating of the yarns may be effected before or after they are formed into fabric. The resist may be applied at random along the length of the yarns before fabricformation and the shrinking treatment is carried out on the fabric so as to produce an overall cockled effect. The resist may be applied to the fabric by printing. The subsequent shrinking treatment produces a patterned effect similar to that of fabrics woven on a Jacquard loom or made on a lace-making machine. The resist may be applied locally with the aid of screens, stencils, blocks, or rollers. The shrinking agent may be acetaldehyde, acetic acid, acetone, diacetone alcohol, formaldehyde, ethylene chloride, or ethyl alcohol. It may be mixed with a diluent e.g. benzene, carbon tetrachloride, toluene, xylene, or kerosene. The shrinking agent and the diluent are chosen so that they have little or no solvent action on the water-soluble polyvinyl alcohol resist. The fabric treated mav be a woven, knitted or netted fabric and it may consist entirely of yarns of an organic derivative of cellulose or it may also contain yarns which are unaffected by the shrinking agent e.g. cotton, silk, wool, or regenerated cellulose. The yarns may be spun from staple fibres of an organic derivative of cellulose blended with staple fibres of cotton, silk, wool, or regenerated cellulose. The temperature and time of treatment with the shrinking agent are adjusted according to the activity of the agent and the degree of shrinking desired. The shrinking agent may be applied by dipping, spraying, or padding methods. The cellulose derivative may be cellulose acetate, butyrate, aceto-propionate, or other ester, or ethyl, benzyl, or other cellulose ether.

Abstract: 527,872. Type-casting machines. BADER, K. April 21, 1939. No. 12115. [Class 100 (iii)] Metal-pots.-In means for supplying metal to the metal-pot, the descent of an ingot is controlled by a hydraulic cylinder, the movement of the liquid in which is regulated by a valve operated by a float on the surface of the molten metal. The ingot 3. Fig. 1, is suspended from a chain 8 passing over a sprocketwheel 12, to which is secured a pinion 11 gearing with. a rack formed on the pistonrod 10 of a cylinder 13 containing oil or other liquid. The liquid can pass from one side of the piston to the other through a pipe 18, which is normally closed by a spring-pressed valve 17. When the metal level falls, a float 5 acts through a lever 16 to open the valve 17, and the passage of liquid to the upper side of the piston permits the ingot to descend. The ingot is supported from a hook on the chain by a hook-shaped portion 25, Fig. 2, having a shallow crook, which falls off the supporting-hook when the body of the ingot has been melted.
