Title: Flame spray gun
IPC: B05B7/20
Filed: 1965-10-11
Abstract: 1,117,365. Spray, producers. METCO Inc. 11 Oct., 1965 [11 Jan., 1965], No. 43064/65. Heading B2F. [Also in Division F2] A wire type flame spray gun has a wire feed drive train including a wire feed roller, the speed of which is controlled by a speed governor, and torque-sensing means which directly senses changes in the torque required to drive the feed roller independent of a change in the speed of the drive and which varies the power output of the drive transmitted through the drive train to increase the power output as the torque increases and to decrease it as the torque decreases. Feed rollers 8 and 9 are driven through a gear train comprising worm gear 17 Fig. 2 on shaft 16, meshing with worm 18 on shaft 19 Fig. 4, shaft 19 being rotatable by worm gear 20 meshing with worm 21 connected to turbine shaft 22 bearing turbine rotor 23. Brake disc 24 is axially displaceable along shaft 22 and a centrifugal power absorbtion speed governor comprising spring 25 and flyweights 26 is connected to the turbine rotor to maintain a constant speed by operation of disc 24 against annular brake shoe 30. Shaft 22 mounted for limited axial displacement against disc spring 42 constitutes the torque sensing means. With an increase in the drag on feed rollers 8 and 9 (e.g. caused by a greater drag on wire 6) there is a greater torque in worm 21 and the axial component of this torque moves shaft 22 towards and against the force of spring disc 42, thus decreasing the pressure of brake disc 24 on shoe 30 and increasing the power available in the drive train. A decrease in the torque in the drive train will have the reverse effect. In alternative embodiments the drive train may include mating bevel gears (Fig. 7) or mating couplings carrying serrated teeth (Fig. 6) which components move apart against a spring force as the torque increases, thus varying the braking force. Similar torque sensing means may be used in conjunction with other power regulating devices e.g. movement of shaft 22 may vary an electrical resistance in an electrically powered drive train. Wire 6 is fed from rollers 8 and 9 into a pasage extending through gas head 3 to nozzle 4 which has a central wire feed passage and is supplied with a ring of burner jets fed with a combustible gas mixture. A blast gas e.g. air, is fed through valve (5) and air cap (4 Fig. 1 not shown), to impinge on the heat-softened tip of the wire, continuously atomising it and propelling the atomised particles as a spray away from the gun. The gun may be used for spraying metals and refractory oxides.

Abstract: 1,093,740. Embossing. KENDALL CO. Sept. 28, 1966 [Oct. 4, 1965], No. 43388/66. Heading B6J. A sheet of deformable textile material is embossed by means of two rollers, at least one of which is heated, engraved with a pattern of lands 14 and grooves 16, producing an embossed pattern comprising discrete areas 52 of greatest depression where lands on both rollers engage, areas 50 of partial depression where a land engages a groove, and unaffected areas 48 where grooves are in register. The pattern may be helical, Fig. 1, and the lands may incline differently or oppositely and be of different thicknesses on the two rollers, or may be circumferential on one roller. Alternatively, the lands may be formed of separate elliproidal rings inclined to the roller axis, but in this case the relative angular position of the two rollers is critical. In some cases, the deepest embossed areas may become perforations. The sheet may be an array of thermoplastic and absorbent fibres, e.g. polypropylene and viscose rayon. The sheet may be mounted on a substrate such as woven fabric, or paper, or a bonded or unbonded non-woven fabric. The sheet may also be an adhesive tape. With a web of polypropylene fibres, using rollers heated to different temperatures, the fibres are fused together in the areas where lands co-operate, forming nodes 73, Fig. 13, in an open pattern. In the case of an adhesive tape comprising a cellulose acetate satin backing fabric coated with a heptane solution of a pressure-sensitive adhesive, and using the rollers of Fig. 1, the adhesive is formed into a set of continuous ridges with intervening troughs of thinner adhesive in which are formed spaced apertures.

Abstract: 981,080. Semi-conductor apparatus. STANDARD TELEPHONES & CABLES Ltd. Sept. 29, 1961 [Dec. 23, 1960], No. 44298/60. Heading H1K. Electrical apparatus comprises a plurality of circuit elements, such as tunnel diode storage elements, supported upon a cylindriform surface and operatively connected by conductors making different angles with the axis of the surface. Fig. 1 shows the equivalent circuit of the constructional arrangement shown in Fig. 2. A shifting register for binary intelligence comprises pairs A, B, C &c. of series-connected tunnel diodes 10a, 106. If a positive pulse is applied via conductor 16 to the first stage A while a small positive pulse is applied to 13 the lower diode switches to the high voltage condition before the upper one; a negative pulse to 13 would switch the upper diode first. Binary " 0 " and " 1 " are thus represented according to which diode bears the major part of the applied voltage. If a voltage pulse is then applied to B, this adopts the same state as stage A. Thus an intelligence bit can be passed from stage to stage by applying pulses to conductors 16-19. Once a given stage has adopted the new state, the energizing pulse can be removed from the preceding stage. A new intelligence bit can be fed into stage A only when stage B is quiescent so at least three register stages are needed to store an intelligence bit and ensure its unidirectional transfer through the register. Pulses are supplied to conductors 16 to 19 by means of transfer impulse generator 15 which is described in Specification 898,425. Fig. 2 shows the construction of such an assembly in successive stages progressing left to right. At the first stage a series of semiconductor wafers 31 are fixed along a helical path to the surface of a copper wire 11. Beads 32 of impurity are then added and an alloying process performed to transform each into a tunnel junction device. A layer of insulation 33 is sprayed on which is partly removed to expose beads 32 which are connected to a nickel-chrome alloy ribbon 34 wound in helical fashion. A series of second semi-conductor wafers 35 are then soldered to ribbon 34 and the process repeated to form the second series of tunnel diodes the beads of which are connected to one of the four transfer conductors of copper foil 38 which correspond to conductors 16-19 of Fig. 1. The ribbon 34 corresponds to the signal input connection 13, and its resistance constitutes resistors 14 and 12 of Fig. 1, and wire 11 to the common lead 11. The assembly is completed by a final wrapping 39 of insulation. More than one axial conductor may be provided. Specification 898,425 is referred to.

Abstract: 975,648. Reactor control rods. GROUPEMENT ATOMIQUE ALSACIENNE ATLANTIQUE. Nov. 11, 1963 [Nov. 12, 1962], No. 44418/63. Heading G6C. In a nuclear reactor neutron absorbing rod intended principally for use as an emergency shutdown rod, the problem of absorbing kinetic energy resultant from rapid braking of the rod is solved by providing a control rod comprising a plurality of tubular elements which slide telescopically partially within one another and which are each supported by one of the adjacent tubular elements; one of the two end elements carrying an abutment for contact with the reactor core, and the other providing an attachment for a suspension member. The rod may be used simultaneously as a control rod and as a safety rod, the suspension cable displacement being controlled in the former case and uncontrolled in the latter case. Each of the elements 2 may contain a neutron absorbing material ring, or the elements may themselves be constructed of such a material. In the embodiment shown, the rod is telescoped, when not in use, above the core 10, and is suspended by a steel wire 4 attached to the lowest element. In a modification (Fig. 2, not shown), the rod is suspended from the topmost element, and is thus in extended form when withdrawn from the core, and in telescoped form when inserted. By this means, the kinetic energy to be dissigated by arresting the rod movement is expended as a series of small shock loads, and no further damping is required.
