Patent GB-805526-A (GB)
Title: Method for clarifying water
IPC: C02F1/52
Filed: 1956-11-15
Abstract: Water is clarified by mixing with it a coagulant and an acrylamide polymer.  The coagulant is chosen from ferrous sulphate, ferric chloride, chlorinated ferrous sulphate, sodium aluminate, aluminium sulphate and aluminium chloride.  The acrylamide polymer may be polyacrylamide of a copolymer of acrylamide with up to 15 mole per cent. of other polymerizable substances such as acrylic and methacrylic acids and their alkyl esters, acrylonitrile, methacrylonitrile, methacrylamide, vinyl alkyl ethers, styrene, vinyl chloride and vivylidene chloride. The polymer or copolymer may contain free carboxyl groups, resulting from the copolymerization of acrylamide with acrylic acid, or from the partial hydrolysis of amide groups subsequent to polymerization.  The coagulant and acrylamide polymer may each be added in the form of a powder or of an aqueous solution.  Where the polymer is added in the form of a powder, it may first be mixed with an inert carrier such as diatomaceous earth, clay, pryrophillite or talc.  The process may be applied to the removal of finely divided solids such as silt or clay from river or lake water.  In examples (a) alum (with or without sodium silicate) and acrylamide polymer is added to river water, (b) ferric chloride and acrylamide polymer is added to river water, the pH of the water being adjusted to 6 by the addition of sodium hydroxide, (c) an aqueous effluent containing fine coal and clay in suspension, and obtained in the recovery of foundry sand by washing, is treated with aluminium sulphate and acrylamide polymer, and (d) ferric sulphate and acrylamide polymer is added to a brine obtained from a shale formation.  Reference has been directed by the Comptroller to Specification 768,665.

Abstract: 1,274,035. Rotary drum mixers. STATNI WZKUMNY USTAV KOZEDELNY. 14 July, 1969 [12 Sept., 1968], No. 35405/69. Heading B1C. [Also in Division C6] In a rotary drum mixer primarily for mixing, homogenizing and/or tanning hide collagen fibres, a short cylindrical body 1 is connected by frusto-conical portions to flat ends 2, 3 and is mounted on hollow trunnions 5, 6. There are longitudinal baffles 9 which extend to the ends of the drum and have in the middle of their inner edges recesses 10. The trunnion 5 is used as charging and discharging part; if the drum be rotated clockwise as depicted in Fig. 2 (not shown) the material is tumbled by the baffles 9, the recesses 10 giving an axial movement to prevent spillage through the trunnions, but reversal of the direction of rotation causes a trough 12 to deliver material to a pocket 13 whence it is discharged. The trunnion 6 abuts a stationary plate 14 through which passes a perforated liquid discharge pipe 15 the other end of which rests in a pivot 16. During mixing a collecting funnel 20 attached to a baffle 9 discharges material into the enlarged end of a stationary pipe 15 which conveys it to a sampling or measuring device 18, whence it is returned by a pipe 19 to the drum.

Abstract: 1437424 Hydrostatic transmission control KOEHRING CO 26 July 1973 [13 Sept 1972] 35598/73 Heading F2W In a hydrostatic transmission for control of the swing of the boom of, e.g., a crane, a fluid motor 12 is supplied with fluid under pressure from a variable displacement pump 11, the swash plate 13 of which is adjusted by pressure fluid supplied to servos 14 and 15 under the control of a valve assembly 23 and a mechanical feedback linkage between the assembly 23 and the swash plate 13. A control lever 33 adjusts an air pilot valve 22 to supply a pneumatic signal to a converter 24, which in turn supplies oil under pressure from a pump 25 to either a pilot port 30 or 31 (the other being vented) in assembly 23. Assembly 23 comprises a valve 36 having a spool 37 and a valve 40 having a spool 41 in the illustrated embodiment, charge pressure for pump displacement adjustment being supplied to a port 60 and ports 61 and 62 being connected to drain. On pilot pressure being supplied to port 31 valve spool 37, centred by springs 55, is moved to the left (the position shown) to put port 60 in communication with a port 63 and pressure is also applied to the right hand side of spool 41 (chamber 72) to move this to the left against the force of a spring 88 which acts between an abutment 97 on a pivoted member 90 linked to the spool 41, and a fixed abutment 98. This movement of spool 41 brings port 63 into communication with a port 76 from which fluid passes to servo 14 to adjust the pump swashplate 13. A link 104, pivoted at 105 to the swashplate 13 and a further link 100 interconnects swashplate 13 and spool 41. The movement of the swashplate 13 tensions spring 88 further and the spool 41 is returned to the central position shown when the force of this spring equals the pressure in chamber 72, so that the adjustment of the swashplate depends on the pressure supplied to the pilot port 31. The load on the motor is reflected in the pressure in the servo which holds the pump adjusted, 14, if pilot pressure is supplied to port 31, which pressure is transmitted through a groove 75 in a land 73 of spool 41 and an orifice 65 to a chamber 57 of valve spool 37, which pressure opposes that from port 31, in chamber 54, and so the spool 37 is moved to the right if this load is too great. This movement connects port 63 to drain and with spool 41 to the left of centre the servo 14 is connected to drain until the load is reduced. On return of the control lever 33 towards neutral the pressure at port 31 is reduced, spools 41 and 37 move to the right and the pressures in servos 14 and 15 reverse, thereby braking the motor 12. In an alternative embodiment (Fig. 7, not shown) the groove 75 and orifice 65 are replaced by a bore in the spool 37. With the lever 33 in its neutral position the motor 12 can rotate freely since neither servo 14 or 15 will be pressurized and so the motor 12 can move the swashplate of the pump by means of the fluid flow when the motor rotates. The system can work in reverse due to its symmetry.

Title: A method of and apparatus for feeding tobacco to mechanism for forming a continuous tobacco filler
IPC: A24C5/39
Filed: 1936-12-29
Abstract: 488,029. Cigarette-making and like machines. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. Dec. 29, 1936, No. 35613. [Class 130] In feeding tobacco to mechanism for forming a continuous tobacco filler, a stream of tobacco is formed by positioning tobacco at the rear end of a stream of tobacco movable in one general direction, separating strips of tobacco from the leading end of the stream, and directing the separate strips towards the said mechanism. In the apparatus shown in the Figure, tobacco from the carded roller of a feed hopper is showered by a picker roller upon a smooth high-speed roller 15 and passes through a confining passage formed by the surface of the roller and a curved plate 16 pivoted at 17 and connected to an eccentric strap 18, by which it is moved towards and away from the surface of the roller. The stream of tobacco built up in this confining passage is impeded by a plate 49 carried by an arm 50 pivoted at 51 and actuated by a cam 53 to move the plate into and out of the path of the stream. Strips of tobacco are separated from the stream by a blade 55, which may have a serrated edge and is clamped to a carrier 56 actuated by a pair of crank-pins 57, 58 on shafts 59, 60. The separated strips fall into a receptacle formed by projections 36 on a roller 35 and are deposited on a band 32 travelling in the bottom of a trough 33 forming part of mechanism for forming a continuous tobacco filler. A guide 37 surrounds the projections 36 and the roller 35 is rotated intermittently by means of a Maltese - cross drive comprising rollers 40 motmted on a pinion 39 and engaging non- radial slots 41 in a disc on the shaft 34. In an alternative construction, Figs. 1 to 3 (not shown), the means for severing tobacco strips from the stream and conveying them to the band 32 is that described in Specification 488,027. Specification 459,607, [Group VIII], also is referred to in the Complete Specification and Specification 441,402 in the Provisional Specification.
