Title: Improvements in or relating to means for conveying materials, suitable for use in weighing apparatus
IPC: G01G21/00
Filed: 1942-08-17
Abstract: 563,718. Hydraulic machines. THOMAS, C. W., and RUDDICK, H. G. Aug. 17, 1942, No. 11507. [Class 69 (ii)] [Also in Groups XXX and XXXII] A weighing pan 16 is fed by a conveyer trough or band 14 which is vibrated from a rotating cam 6 through a column of fluid contained in a tube 1. The tube 1 terminates at its lower end in a block 3 mounted in a reservoir 2 filled with the fluid and traversed by a crossduct 17. A piston or diaphragm 4 closes the lower end of the tube 1 and is pressed up by a spring 8 contained in a cap 5 moving up and down with the cam 6. The upper end of the tube 1 is closed by a piston or diaphragm 10 connected by a rod 11 to one arm 12 of a bellcrank linked by its other arm 12a to one end of the conveyer trough 14, the other end of which is supported by a spring 14a. A piston 18 enters one end of the duct 17 and a ball valve 21 closes the other end. Normally, the pressure on the fluid is too low to overcome the spring 8, and the reciprocation of the cap 5 produces no effect. When a solenoid 19 is energized at the beginning of a weighing operation, however, the piston 18 is pushed in, thus increasing the fluid pressure to force down the spring 8 and allow the piston 4 to reciprocate with the cap 6. The impulses thus imparted to the fluid give the piston 10 a similar motion and so vibrate the trough 14. A valve 23 may be actuated manually to restrict the vibrations, or be operated automatically either electrically or mechanically with movement of the pan 16. In a modification suitable for continuous delivery, the piston 4 bears directly on the cam 6 under spring pressure, thus rendering the piston 18 unnecessary as the piston 4 will then build up the necessary pressure automatically by suction of fluid from the reservoir 2 through the valve 21 should the pressure fall. The vibrating device may be applied to sieves or hammers &c.

Title: Improvements relating to sludge washing apparatus
IPC: B01D11/02
Filed: 1953-04-27
Abstract: 728,791. Treating solids with liquids. ZDANSKY, E. A. April 27, 1953 [May 12, 1952], No. 11597/53. Class 82 (1). In apparatus for washing dissolved or soluble substances out of sludges by repeatedly sedimenting the solids in counterflow to a washing liquid, comprising a vertical column 1 with a series of sedimentation zones A, B and C from each of which the solids pass through a conical member 4 and are then distributed over the next sedimentation zone by a distributer 5, a pipe or pipes 8 and an associated non- return valve are provided for conducting the washing liquid out of each sedimentation zone, and slurry may be withdrawn through the valve 17 for brief periods under automatic closure of the said valves. In an alternative form, the bottom of each sedimentation zone may comprise a number of cones arranged in honeycomb fashion and the pipe for carrying the liquid mounted between them. Washing liquid enters through pipe 16 and after final clarification in the cone 9 passes out by the overflow 10. The sludge is introduced into cone 9 through apertures 14.

Title: Steam or hot water boiler, furnace or other apparatus having a combustion chamber under pressure in relation to the heat-absorbing parts of the apparatus
Inventor: RYDBERG JOHN ANDERS
IPC: F28D19/04
Filed: 1951-05-17
Abstract: 700,524. Pressure-exchangers. AKTIEBOLAGET GUSTAVSBERGS FABRIKER. May 17, 1951, No. 11602/51. Class 8 (1). [Also in Group XIII] Relates to apparatus such as a boiler or furnace having a combustion chamber 7 under presure in relation to the heat-absorbing parts 10, e.g. water-filled walls of a boiler, and from which chamber the hot combustion gases are taken at high pressure by a pressure-exchanger comprising a rotor 1 rotating in a casing 2 having a high-pressure inlet 5 at which the hot gases enter to be conveyed to a low pressure stage and there be replaced in the cells of the rotor by an equal volume, at lower pressure, of Àcolder and therefore heavier gas entering by an inlet 3 to displace the hot gases into an outlet 4. Moreover, the cold gas is returned to the high-pressure stage and forced out of the cells by further hot gas from the inlet 5 so that the whole exchange results in the transfer of a larger weight of gas from the low-pressure stage to the high-pressure stage than in the opposite direction and thus the hot gases are delivered to the heat-absorbing part 10 at a lower pressure than prevails in the furnace. According to the invention, the surplus gas resulting in the furnace from the pressure-exchange is by-passed directly, e.g. by a duct 19, to a low-pressure region 20 located before, or comprising, the inlet to the heat-absorbing parts 10 and in this region the gas, being injected by a nozzle 21, draws with it and compresses the hot gas from the casing outlet 4 so that hot gas at high velocity passes through conduits of the heatabsorbing parts 10. The low-presurse hot gas from the outlet 4 is pre-compressed by a jet from a nozzle 25 fed by bleeding gas from the pressure-exchanger. As shown, cold air enters the exchanger at the inlet 3 and in a compressed state passes from an outlet 6 by a duct 8 to the furnace 7 to be used for combustion and maintain the pressure therein above atmospheric, the pressure in the heat-absorbing part 10 being about atmospheric. In a modification, Fig. 2 (not shown), the pressure in the furnace is about atmospheric, and in the heat-exchanging part 10 it is lower than this, duct 8 and the outlet 6 being unconnected but open to atmosphere and the outlet of the part 10 being connected to the inlet 3 so that the pressure-exchange is between fresh and spent combustion gases with the latter discharging at 6. The fraction of the hot gases which passes through the pressure-exchanger may be pre-cooled to prevent damage to the exchanger. The jet pump 20, the various ducts and the exchanged casing 2 are air or watercooled, Fig. 5 (not shown). Air or water may flow through the exchanger shaft for cooling.

Abstract: 474,053. Compound fabrics. BRITISH CELANESE, Ltd. April 24, 1936, No. 11731. Convention date,'April 24, 1935. Addition to 462,242. [Class 140] A stiffened compound fabric suitable for wearing-apparel, e.g. for collars, cuffs, fronts, &c. of shirts, hats and parts thereof, and linings, is made by uniting under heat and pressure in the presence of water an assembly of fabrics each containing filaments or fibres of a thermoplastic cellulose derivative, at least one fabric containing both a water-soluble and a waterinsoluble plasticizer for the cellulose derivative, and at least one fabric containing no plasticizer. The assembly may comprise two cellulose derivative fabrics, one free from plasticizer, or three fabrics, the middle one being treated with the plasticizers. The appearance of the outer plasticizer-free fabrics is substantially unchanged after pressing, and part or all of the water-soluble plasticizer may be washed out subsequently. Suitable water-insoluble plasticizers are dimethyl-, diethyl-, or dimethoxyethyl-phthalate, and water-soluble, dimethyl- or diethyl-tartrate, and mono-, di-, or triacetin. A mixture of dimethoxyethyl-phthalate and triacetin is useful for cellulose acetate fabrics. The plasticizers may be incorporated in the solution from which the cellulose derivative yarns are formed, or may be applied to the fabric, e.g. by spraying or dipping, from a solution in benzol, ethyl, or methyl alcohol. The fabrics may be woven, knitted, or netted, may consist solely of cellulose derivative yarns, or may comprise also cotton, regenerated cellulose, linen, wool, or natural silk yarns. Fabrics made from mixed yarns comprising cotton and cellulose acetate fibres or filaments may be used. Two layers of cellulose acetate or mixed fabric may be united to an intermediate cellulose acetate or mixed fabric treated with plasticizer. Pigments such as titanium dioxide, antimony trioxide, and lamp black may be present in the assembly. The fabrics may be cut to shape an:l sewn together before union. The plasticizer and the heat and pressure may be applied locally. Cellulose formate, propionate, or butyrate, ethyl- or benzyl cellulose may replace cellulose acetate.
