Patent GB-759997-A (GB)
Title: Aerodynamic classifier
IPC: B07B7/08
Filed: 1954-12-09
Abstract: 759,997. Pneumatic separators. MICROCYCLOMAT CO. Dec. 9, 1954 [Feb. 17, 1954], No. 35640/54. Class 117. A controlled supply of dry pulverent solid material in a carrier gas is fed by a feeder 64 tangentially at 67 to a rotary classifier mounted within a housing 10, and the material collects in a bed at the bottom of the housing. The action of the classifier rotor above the bed maintains it in a turbulent state, and the oversize and denser particles settle to the bottom of the bed and are discharged from an adjustable opening 72 and carried away by a conveyor 74. Smaller particles of desired size are drawn from the bed into the periphery of the rotor, and are finally drawn by a suction fan axially through the rotor to a discharge outlet which leads to a collector for separating the particles from the gaseous carrier. The classifier rotor is mounted on a shaft 29 and is in the form of a cage enclosed between annular end plates 49, 50 and is divided into sections by annular rings 54. Rods 55 are arranged around the peripheries of the plates and rings, and spaced inwardly therefrom are rods 56, Fig. 4, on which spaced annular discs 57 are mounted. The discs 57 form a drum-like structure and their inner peripheries are spaced from a tube 30 secured to the shaft 29 to provide an annular passage 60, Fig. 1. A centrifugal fan impeller comprising blades 40, 41, is also secured to the shaft and is mounted within a housing 16 spaced from the classifier housing. Due to the rotation of the rotor, air vortices 95 are set up between adjacent rods 55, Fig. 6, and the finer particles are drawn into those vortices and the depth reached by the particles within the rotor periphery is inversely proportional to their mass or size. The separation of the particles from the vortices is effected by the fan which draws air in a controlled manner into the rotor periphery and carries the particles through the passage 60 to the fan outlet. The spaces between the discs 57 provide intake ports which are positioned in relation to the circulating particles of the required size. A damper in the fan outlet controls the fan suction, and a frusto-conical spacer ring 61 equalizes gas flow through the rotor. The depth of the particle bed is preferably maintained substantially constant by automatically controlling the feed of material to the apparatus. For this purpose pressure sensitive elements controlling the feeder 64 may be set in the walls of the classifier housing on opposite sides of the bed. Instead of a belt conveyor 74 a corrugated or toothed roller may be positioned at the discharge opening. In order to maintain the bed in a fluent state a part of the bottom of the classifier housing may be perforated, and an additional air supply fed to the perforations.

Abstract: 176,908. Timpany, D. C. Dec. 20, 1920. Washing-machines with swinging beaters, rubbers, or squeezers in stationary receptacles, of the type described in Specification 13474/00 comprise in the receptacle an oscillating rubber and a reciprocating bumper connected together by torsional springs, and arranged so that they may be jointly operated by means of a handle which causes the bumper to be drawn towards the rubber, so squeezing articles placed between them, and upon the springs being overcome permitting the rubber to oscillate alone, thus producing a rotary as well as an horizontal movement of the articles, and are provided with means for adjusting the strength of the spring. The oscillating convex rubber is composed of wooden ribs or slats d longitudinally fluted or recessed to increase their rubbing effect, and metal side or cheek members e pivoted on axles f secured by an integral plate f<1> to the inside of a tub a, having wooden sides and a galvanized iron bottom; the rubber is actuated by a frame handle g by means of links h connected to the cheek members d by lugs d<1>. The bumper j is composed of wooden ribs or slats of which the interior faces are longitudinally grooved and the ends are secured to curved side arms k connected to the tub by link bars l. An horizontal spindle m extends inwards from each side cheek e, having at the end adjacent to the tub a lever n n<1>, with a ring extremity n<2> pivoted about a pin o in the side arm k; each spindle m has coiled round it a helical spring p, of which one end is attached to a collar q on the outer end of the spindle, and the other is connected to an arm r revolubly mounted on the spindle, and having a projecting portion r<1> which may be entered between any two of the spaced projections s in a quadrant integral' with the lever arm n<1>. The spring normally maintains the arm n<1> against a stop e<1> of the cheek e. By movement of the lever arm n', the compression of the spring p may be regulated so as to adjust the pressure on articles between the rubber and bumper.

Title: Method of and apparatus for inscribing an identification number in binary code on a metal component and reading the said number
IPC: G06K1/12
Filed: 1972-07-31
Abstract: 1355732 Blasting COMMISSARIAT A L'ENERGIE ATOMIQUE 31 July 1972 [6 Aug 1971] 35705/72 Heading B3D [Also in Division G6] The identity of a nuclear fuel element is established by labelling the can in binary code by means of sandblasting. Each can is passed, in turn, to a sandblasting box 3 and undergoes rotation therein. The box defines equally spaced, parallel slots 8 through which fine glass balls can pass from a nozzle 9 to impact the can. Associated with each slot 8 is a pipe 10 for conducting compressed air to selectively deflect the jets of balls. Thus, where a binary "1" is to be recorded, the relevant jet is deflected so as not to impact the can thereby leaving it unmarked; while where a binary "0" is to be recorded, the jet remains undeflected thereby sandblasting an annulus on the can.

Abstract: 1435488 Fibrous polymer particles BP CHEMICALS INTERNATIONAL Ltd 23 July 1973 [1 Aug 1972] 35903/72 Heading B5B [Also in Division D2] Fibrous polymer particles are made by subjecting a flow of a crystallizable polymer to a fluid stream to produce an elongational stress in the solution and allowing the polymer to crystallize while subjected to the elongational stress and to form fibrous polymer particles. Preferred polymers are high density polyethylene and polypropylene, and specified solvents include cyclohexane, n-hexane, n- .heptane, n-pentane, isopentane, xylenes, benzene, toluene, methylene dichloride, methyl chloride and mixtures thereof. A 1 to 15% by weight solution of high density polyethylene in xylene or cyclohexane is preferred, having a solution viscosity of 10<SP>2</SP> to 10<SP>4</SP> poise, and which may contain fillers, pigments, surface-active agents, anti-statics, or other paper-making additives, and the rate of flow of the solution may be 0À5 m. to 200 m./sec. The fluid stream may be nitrogen, carbon dioxide, or steam, water or superheated water, and may impinge on the polymer at an angle not greater than 30 degrees. Thus it may be directed at the flow of solution 3 as the latter emerges from a nozzle 5 mounted coaxially inside a nozzle 10 carrying the fluid -stream. Suitably the fluid stream is at a temperature of 20‹ to 160‹ C., and its rate of flow at least 10 times the rate of flow of polymer solution when a gas is used and at least 3 times when a liquid is used. Particles so made may be of length 1 to 10 mm., with an average degree of crystallinity of at least 10%, preferably 25 to 100%. The fibrous polymer particles may be deposited in the form of a sheet, e.g. by laying down on a mesh grid under gravity or by their own inertia, or the fibres may be used to make an aqueous pulp from which sheets are formed on conventional paper-making machinery. In apparatus as shown in Fig. 2, the fibrous polymer particles are collected on a gauze and provision is made for recovery of the solvent.

Abstract: 1,056,583. Speed-change control. FORD MOTOR CO. Ltd. Aug. 26, 1965 [Sept. 21, 1964], No. 36661/65. Heading F2D. In a vehicle automatic transmission of the type in which servo pressure for operating ratioestablishing clutches and brakes is controlled by a regulator valve subjected to conjoint action of throttle variable and governor valves, the regulator valve has a boost valve normally connected to the TV valve, but which is rendered inoperative by a cut-back valve in the event of excessive speed, e.g. during acceleration, when the torque requirements of the servo elements are reduced. System details.-The gear arrangement consists of an hydraulic torque converter 18 followed by an epicyclic gear with servo clutches 32, 36 and brakes 38, 64. Pressure liquid from a pump 80 is supplied to a 1-2 shift valve 268 and a 2-3 shift valve 270, Fig. 2B (not shown), incorporating a throttle modulating valve 318, through a main regulator valve 88, the lower end of which is subjected to the action of a boost valve 116. Also included are a manual range selector valve 200 and a throttle boost valve 332 (not shown). The governor valve 70 on tail shaft 62 and TV valve 154 having an engine manifold connection 188, in addition to the normal connections 262, 400 to the regulator valve 88, have input connections 428, 432 to the cut-back valve 416 which has differential lands 420, 424 and an output connection 434 with the regulator boost valve 116. A coasting boost valve 402 is mounted in parallel with the cut-back valve 416. Operation.-Normally the TV pressure in line 432 holds cut-back valve 416 in the position shown and is communicated through lines 434, 130 to differential lands 122, 124 of regulator boost valve 116 and thus augments the main servo pressure. In the event of excessive pressure rise in governor line 428, this pressure acting on the underside of valve 416 moves the latter upwards to cut off the connection 434, so that the servo pressure is reduced, being determined solely by the relationship between the TV and governor pressures in lines 262, 400. The coasting boost valve 402 is normally held in the position shown by a loading spring 410 so that TV pressure in lines 400, 412 is applied to the underside of regulator boost valve 116, but in the event of coasting at high speed with engine braking the governor pressure acting on the top of valve 402 forces it downwards to establish communication between passages 412, 414 and thus connect control pressure to the underside of boost valve 116 to augment the servo pressure.
