Patent GB-1284199-A (GB)
Title: Photoanalysis apparatus
IPC: G01N15/14
Filed: 1971-01-12
Abstract: 1284199 Inspecting particles photo-electrically BIO/PHYSICS SYSTEMS Inc 12 Jan 1971 [14 Jan 1970] 1339/71 Heading G1A [Also in Division G2] In an apparatus for measuring simultaneously a plurality of characteristics of each of a group of small particles, e.g. blood cells, which are carried in sequence by a carrier liquid stream 19 past an inspection point 38 in a capillary tube 10, a plurality of photo-cells 40-52 are arranged at different angular positions with respect to the incident beam direction, at least two of the detectors each providing an indication of a different characteristic of each particle as a result of receiving radiation modified by the particle. The flow of the carrier liquid 19 is restricted to the centre of the capillary 26 by a sheath liquid 23 which forms a flowing envelope around the carrier liquid. The upstream portion 24 of the bore may be of exponential shape to facilitate non-turbulent flow.  As each particle crosses the inspection point 38 it is irradiated with collimated light from a laser 30. Transmitted light is received by a detector, e.g. silicon photo-cell, 40. The detector pair 42/44 placed symmetrically with respect to the incident beam receives radiation scattered within a certain angular range. Another detector pair 47/48 monitors radiation scattered in a different angular range, and detector pair 50/52 monitors an angular range of back-scattered radiation. The detectors are so positioned that the output of each detector pair is indicative of a different characteristic of each particle. These outputs may be displayed on a digital counter or recorded. In this way the particles may be differentially classified, in particular the number of dead and live blood cells in a sample may be counted. Fluorescence radiation may also be monitored Fig.2A (not shown), this technique being used to investigate blood cells stained with dyes which fluoresce at different wavelengths. Fluorescence radiation from each particle is directed on to a beam splitting dichroic mirror (69) by two curved collecting mirrors (63, 65). Two photomultipliers (73, 77) having associated filters (71, 75) receive the two divided components. In a further embodiment, Fig. 5 (not shown) forward scattering is measured by a single pair of symmetrically-placed photo-cells. Each photo-cell (68, 70) is of the type which gives one output indicative of the incident light intensity and another output indicative of the position of the incident beam. The corresponding outputs from the two detectors are combined. In all the embodiments it is possible to replace a detector pair with two mirrors directing radiation on to a single detector. Also each detector may have an arcuate receiving surface, Fig.4 (not shown) to enable more radiation in a given angular range to be received.

Title: Improvements in roasting of sulfide ore concentrates
IPC: C22B1/10
Filed: 1955-01-17
Abstract: A modification of the method of roasting iron sulphide such as pyrite or pyrrhotite in a multi-bed fluidized column by introducing roasting air into at least two vertically spaced points in a vertical column containing the sulphide, and withdrawing the roaster gases from the top of the column, as described in Specifications 660,778 and 661,560, is characterized in that the major portion by weight of the fluidized materials throughout the operation consists of coarse particles of previously roasted iron sulphide having a particle size between 6 and 35 mesh, the iron sulphide being charged to the column in finely divided form at a point below the upper surface of the uppermost fluid bed of the column, the rate of introduction of the charge being adjusted to maintain the temperature of the column at the incipient fusion temperature of the sulphide, preferably 50 to 75 DEG C. below the softening temperature of the column, whereby the roasted iron sulphide charge is withdrawn from the lower portion of the column in the form of discrete particles larger than the size of the iron sulphide particles charged, but not substantially larger than the relatively coarse particles of which the fluidized column is largely composed.  The roasting air supplied to the column is preferably 5 to 20 per cent in excess of that theoretically required and may be distributed according to the above Specifications, for example such that the lowermost bed has an apparent density of 75 to 90 per cent of the unexpanded bulk density of the particles, the next uppermost bed having an apparent density of 55 to 75 per cent, and the uppermost bed has an apparent density of 40 to 60 per cent.  The uppermost end of the column may be provided with an enlarged cross-section whereby loss of fines may be prevented.  The temperature of the fluidized column will depend on the pyrites employed that is normally from 1040 to 1060 DEG C.  The finished calcine consists predominantly of magnetite and a roaster gas containing about 14 per cent sulphur dioxide may be obtained.

Abstract: 1453126 Seaming METAL BOX Ltd 20 Feb 1975 [11 Jan 1974] 01416/74 Heading B3J Apparatus for seaming ends on to oval, rectangular or other non-circular containers 10, Fig. 23, by plunging a seaming roller 152B against the end during only a small part of the rotation of the end and container relatively to the roller, as distinct from the method of gradual approach during several rotations, comprises a chuck 21, a cam, a seaming head 124 for rotation relatively to the chuck, a simple rocker 128 on the head 124, a seaming roller 152B and a cam follower roll 142B on the rocker, upon relative rotation between the head 124 and the chuck 21 the cam causing the rocker to pivot and the seamings roller 152B to plunge towards the chuck, perform a seaming operation with the roller at a constant radial distance from the chuck, and a retraction movement. Thus in theory, a deforming operation could be completed in a single revolution after the plunge movement. As shown, the head carries two first-operation rollers 151A, 151B, Fig.9, and two secondoperation rollers 152A, 152B, each controlled on the plunge principle by a separate face-cam 131A, 131B, 132A, Fig. 13, and (132B), Fig. 15 (not shown). The second-operation rollers follow the first in operation with an overlap, Fig. 19, (not shown), and seaming is completed in less than the two revolutions of the seaming head used to complete a cycle which involves operation of a lift pad 112, Fig. 22, and indexing a turret 80. A can is fed into a pocket (81), Fig. 21 (not shown), on the turret at a first station (102) to which can ends are supplied from a feeder (115). Indexing of the turret carries the can first to an idle station (103) and then to the seaming station where it is pressed by the lift pad 112 against the chuck 21 and held against the turret by a clamp 104 which is applied by a spring and released by linkage operated by a cam (94). The lift pad 112 is operated by a cam 95 and lever 111 from a drive shaft 84. A conveyer 117 operated independently of the seamer discharges the seamed can after indexing to a fourth station. Alternatively, the first and second seaming operations may be performed in different heads between which the cans are transferred by a turret, each head having only two rockers. Tapered profile cams 240, Fig. 25, may be used against which conical follower-rolls 247 are pressed by springs 250. The vertical position of the roll 247 on its arm 242 or that of the arm 242 may be adjusted to set the seaming pressure. The seaming head may be stationary and the chuck rotate, or both may rotate at different speeds. Metal cans are used, although the bodies may be of plastics, paperboard or a laminate of plastics and/or paperboard.

Abstract: 606,594. Printing and embossing shelf edgings &c. ROYAL LACE PAPER WORKS. Jan. 16, 1946, No. 1483. Convention date, May 12, 1945. [Class 100(ii)] Shelf edgings or coverings and other ornaments are formed of a transparent plastic ply 7 interposed between a transparent plastic ply 9 and a backing ply 1, the plies 1, 9 being printed by couples P, p<1>, p<2>, P<3> respectively on the sides which contact with the ply 7. The ply 7 is extruded on to the printed ply 1 as this passes over a conveyer 2, and the ply 9 passes over a roll 10 to bring it into contact with the ply 7. After passing over a table 3, which may be heated, the compound material is passed between embossing or indenting rollers 11, 4, which produce an embossed design in relief on the upper side of the compound material, and in intaglio on the lower side, the embossed designs being in register with the printed designs, and the two designs are correllated so as to produce a composite pattern such as the flowers and leaves &c. of a plant. If desired both embossed designs may be in intaglio. The plastic materials may be of thermoplastic or thermosetting nature, and if of the latter in addition to employing heated embossing rollers heating means are added beyond the embossing rollers to facilitate quick setting. The ply 7 may be formed of transparent synthetic resins such as cellulose acetate, cellulose acetate butyrate, acrylic resins, stearine resins, vinyl resins, urea or phenolic resins. Cellulosic materials may be used for the facing or backing ply. The invention may be carried out by flat plate printing operations, and the printed impressions may be on the ply 7 instead of on the plies 1, 9.

Title: Aircraft
IPC: B64C3/54
Filed: 1933-01-19
Abstract: 416,715. Controlling aircraft. ZAP DEVELOPMENT CORPORATION, 230, Park Avenue, New York, U.S.A. Jan. 19, 1933, No. 1855. Convention date, Jan. 19, 1932. [Class 4.] An aerofoil has a flap so mounted beneath its pressure surface that as it is extended downwardly, its trailing-edge lies substantially in perpendicular, dropped from the trailing-edge of the aerofoil in all positions of adjustment. Alternatively, a flap capable of adjustment about its leading edge so as to depend from the pressure side of an aerofoil always forward of the trailing edge, is moved by mechanism substantially wholly within the aerofoil to cause bodily movement of the flap to the front and rear respectively as it is raised and lowered. In one form, Figs. 1, 2 and 3, a flap 25 normally rested against the underside of a wing is moved rearwardly by connections to toothed racks 33 which are movable, parallel to the underside of the wing by pinions 27, and is tilted by links 37 pivoted to the aerofoil and the flap in such position as to produce substantially vertical downward movement of the trailing edge of the flap. The pinions 27 are fast with vertical shafts carrying upper pinions 31 meshed with racks 30 secured to a transversely extending bar 29. At their inner ends the bars 29 on the two sides of the machine carry or are formed with threaded sockets 28 respectively receiving oppositely threaded ends of a rod 24 rotatable by the pilot, for moving the bars 29 inwardly or outwardly, by chain and sprocket mechanism. Ailerons 15 are provided but in a modification, Fig. 15, these are omitted and means provided for moving the flaps differentially. In this case the rack bars 146, 147 are engaged by oppositely threaded parts 144, 145 of a bar 114 having a telescopic joint 116, 117. The bar 114 is rotatable for camber changing by chain and sprocket gearing. Hubs 126, 127 journalled in bearings 128, 129 are formed with internal cam slots 119 in which engage pins 118 on the relatively axially movable parts of bar 114. The hubs 126, 127 are adapted to be oppositely rotated by sideways movement of control column 135. Rotation of the hubs 127, 128 causes axial movement of one or other rack bar 146, 147 to vary the lift on to two sides of the craft. A modified flap mechanism comprises a depending member 90, Fig. 13, in which is slidable a flexible shutter-like flap 96 which may be retracted from operative position by rotation of a reel 95. Modified mechanisms for actuating the.flap involve the use of screw and nut gear operated by bevel pinions on transverse shafts extending into the fuselage, and in one case the flap extends as far as the forward spar of the aerofoil. Fig. 10 shows another modification in which the flap is moved by an arm on a quadrant 76, the forward edge of the flap having rollers 71 moving in guides 73, 72. The flaps may be made of two layers of corrugated metal with the corrugations of the upper layer at right angles to those on the lower surface which extend in the direction of flight.

Abstract: 633,222. Centrifugal pumps. LINDE AIR PRODUCTS CO. Jan. 21, 1948, No. 1899. Convention date, Feb. 1, 1947. [Class 110(i)] In a rotary pump comprising an impeller operating in an annular channel, fluid pressure within a portion of the channel is used for balancing the net force on the impeller produced during the pumping action by an increasing pressure gradient in the channel from the inlet to the outlet end thereof. In a two-stage embodiment, which is used for pumping low temperature liquefied gases, impellers 14, 15 are slidably connected to a shaft 19 by splines 20. The hub 18 of impeller 15 is preferably closed by a plug 40, and is journalled in a bearing 28. The impellers bear against thrust bearings 23, 24. A space around the hub 18 is divided by partitions 34 into two chambers 35, 36. Chamber 35 communicates with the hub region of impeller 15 by way of a hole 37. Chamber 36 communicates by way of a passage 38<1> and passages 38<2>, 38<3> (not shown with the second-stage chamber 12 near its inlet. The radial thrust exerted on the shaft 19 by the pumping action is balanced by a radial thrust caused by the difference of pressure between chambers 35 and 36. A chamber 41 is held at a low pressure, as by means of a passage 42 communicating with chamber 36. so as partially to relieve end thrust on the thrust bearing 24. The invention is applicable to a single-stage pump.
