Title: Liquid fuel burning apparatus
Inventor: LEACH HAROLD WILLIAM
IPC: F23D11/00
Filed: 1959-12-16
Abstract: 893,685. Supplying air to burners. LUCAS (INDUSTRIES) Ltd., JOSEPH. Dec. 6, 1960 [Dec. 16, 1959], No. 42734/59. Class 75(1) In a liquid fuel burner comprising a burner tube 9 movable axially between operative and inoperative positions, the admission of air to a cylindrical air casing 4 from an air chest 6 is controlled by an annular disc 13 axially slidable on a fixed tube 8 and by an annular ring 15 closely surrounding the periphery of the disc 13 and permitted limited axial movement relative thereto. The ring 15 is adapted to seat against the outer end of the air casing 4 and the initial movement of the ring 15 away from its seating is effected without moving the disc 13. The ring 15 is moved by a pair of tubular spindles 17 slidably mounted in bushes 18 in the outer wall 7 of the air chest 6 and clamped in set position by threaded collars 24. The inner ends of the spindles 17 are secured by yokes 19 to the ring 15, and extend through holes in the annular disc 13. The relative axial movement of the annular disc 13 and the ring 15 is determined by an internal flange 16 on the ring and collars 20 on the ends of the spindles 17. A stop 21 on the fixed tube 8 prevents the annular disc 13 from seating on the end of the air casing 4. The outer ends of the spindles 17 are closed by windows 23 one at least of which is detachable to admit of the insertion of an ignition torch through the spindle. A pair of pins on a handle on the end of the spindle actuates a valve and an electric circuit of the torch. A further window is provided in the outer wall 7 of the air chest and is aligned with a pivoted shutter in the disc 13 opened manually or automatically by a projection on the wall 7 when the disc 13 is in the fully open position. Specification 892,933 is referred to.

Filed: 1959-12-16
Abstract: 936,233. Materials for wearing apparel. KUNSTZIJDESPINNERIJ NYMA N.V. Dec. 16, 1959 [Dec. 16, 1958], No. 42814/59. Drawings to Specification. Class 141. [Also in Group VIII] A brassiere or the like incorporates a fabric woven from weft of polythene or other monofilaments and a warp of one monofilament alternating with two threads of continuous filament rayon or spun acrylic fibre; a greater amount of monofilament shows on one side of the fabric than on the other. The cups of the brassiere are made of the fabric with an outer layer of another fabric. In one example, the side of the fabric showing more monofilament is placed next to the skin. In another example, the side containing the smaller amount of monofilament is abraded to raise projecting fibres from the rayon warp, which is woven under low tension so that it tends to hide the monofilament warp; in this case, the abraded side is placed next to the skin.

Title: Method for the electrical control of blast furnaces
IPC: C21B5/00
Filed: 1959-12-17
Abstract: 927,593. Electric selective signalling systems. RHEINSTAHL EISENWERKE MULHEIM/ MEIDERICH A.G. Dec. 17, 1959 [Dec. 20, 1958], No. 42980/59. Class 40 (1). The position at which a rotary hopper drops a charge into a blast furnace is controlled by recording the instantaneous value of the angular position of the hopper in a counting mechanism at a control station where it is compared with an adjustable programme of control commands, and means is provided to control successive values of the dropping position in accordance with the control programme. A rotary hopper is charged on one side at a fixed charging point, and as the hopper is rotated the charge moves away from the charging point towards a selected angular position where it is to be dropped into the furnace. A toothed wheel 3 operates a contact 4 to supply a pulse to a counting mechanism 5 for each degree of rotation of the hopper from the charging point. In response to each pulse, counter 5 steps wiper 6 to apply a positive potential to one of the 360 contacts of twelve switches 7-8 whose corresponding contacts are connected in parallel. Assuming that the programme comprises a sequence of twelve different angular positions, these positions are selected in switches 7-8 by suitable positioning of the selector arm. Switch 9 selects switches 7- 8 in succession, and each time the desired angular position is reached a pulse is supplied to relay 10 which opens contact 10<SP>1</SP> to stop hopper-drive motor 2, and at the same time resets counter 5 to zero. Immediately after resetting, counter 5 is again responsive to pulses, so any over-run by motor 2 is compensated for in the next operation. A fresh charge is loaded into the hopper at the point which stops under the charging point, so that the succeeding rotation is again measured from the charging point. Operation of relay 10 also, through contact 10<SP>11</SP> supplies a pulse to counter 11 to step the wiper of switch 12 to the next position, and, for the straight sequence of twelve angular positions, a pulse is supplied to relay 14 on each successive operation of counter 10. Relay 14 resets counter 11 and applies a pulse to counter 15 so that the next position of switch 9 is selected. By varying the position of the selector arm of switch 12, the number of repetitions of each angular position may be varied. Certain commands set in switches 7-8 may be omitted from the sequence by operating switch 16. The Specification mentions the control of temperature and flow rate of the air blast and of temperature, flow rate and pressure of cooling water by means of a similar system.

Abstract: 1,190,967. Cathode - ray storage tubes. XEROX CORP. 28 Sept., 1967 [29 Sept., 1966], No. 44133/67. Heading H1D. A cathode-ray storage tube wherein the stored information can be read non-destructively comprises a fine mesh screen 6 coated on one side with insulation 8 on which a charge pattern can be set up by a writing beam 22 and coated on the other side with a layer 10 of field-effect semi-conductor which can be scanned by a slow reading beam 42. The charge pattern on the layer 8 produces local fields which extend through the mesh 6 and vary the local conductivity of layer 10 by the field effect. The layer 10 is scanned by a constant current beam 42 which tends to charge the surface to the potential of the cathode 46; between scans the charge will leak off at a rate dependent upon the local conductivity of the layer 10, thus developing a charge pattern, and on the next scan the surface is restored to the cathode potential thereby generating an output signal across the load resistance 12. The insulation 8 may be glass, silicon monoxide or dioxide, calcium fluoride, or aluminium oxide; the semi-conductor 10 may be cadmium sulphide, antimony trisulphide, zinc oxide, calcium oxide, or lead oxide.

Filed: 1966-10-04
Abstract: 1,143,079. Typewriters &c. C. H. HERTZ, and S. I. SIMONSSON. 4 Oct., 1966 [8 Oct., 1965(2)], No. 44356/66. Heading B6F. [Also in Division H4] In an arrangement for producing symbols, pictures, &c. determined by representative electrical signals by utilizing the latter to control a liquid (ink) jet directed against a recording surface moving relatively to the jet, the control means comprises an electrode to which the signals are applied and which diffuses the jet to an extent determined by the signals. The general scheme is shown in Fig. 1, in which the jet 2 which parts into droplets near the nozzle due to the action of surface tension is diffused, as at 9, by the action of the annular electrode 6 supplied with the representative electrical signals from source 7 the diffusion resulting when the charge imparted by electrode 6 to the jet stream overcomes the surface tension of the droplets which then explode into similar droplets each carrying a charge of the same sign so that mutual repulsion results. In the arrangement of Fig. 1, the diffused jet impinges on the (moving) recording surface 3 but produces a much lighter shading than the undiffused jet. Such shading may be prevented by an apertured diaphragm 14 (Fig. 2) which passes the undiffused jet only or by means of an electric field 10 between electrodes 11, 12 which deflects the diffused jet away from the normal axis, a grounded apertured electrostatic shield 13 being utilized to prevent the field 10 from influencing the field close to the jet. Since the electrodes 11, 12 and the diaphragm 14 collect liquid from the jet, means (e.g. suction) are necessary to remove it. When it is required to produce intermediate shades of grey the diaphragm may be positioned as shown at 15 (Fig. 3) so that the amount of liquid reaching surface 3 depends on the solid angle of the diffused jet. Fig. 4 shows a construction for the diaphragm comprising a cylindrical housing 17 apertured at 16 and containing a conically shaped porous disc 18 to receive the liquid not passing aperture 16 and to prevent saturation of the disc liquid is removed by vacuum means applied at 19. A facsimile recording system employing a helically scanned drum mounted recording surface and utilizing a single device of the kind shown in Fig. 3, for black-white reproduction and three such devices for colour reproduction is described with reference to Figs. 5 and 6 (not shown). The recording surface may be replaced by a liquid retaining surface so that, after recording, one or more prints may be produced by rolling the drum over copy paper. In the case of colour reproduction a fourth device of the kind shown in Fig. 3, using black coloured liquid may be employed to improve colour quality. In a further embodiment twenty devices of the kind shown in Fig. 2, are arranged in a 5 x 4 matrix and selectively utilized to form the desired symbols &c. (Figs. 7 and 8, not shown).
