Title: Electrical melting device
IPC: C03B5/033
Filed: 1967-03-23
Abstract: 1,185,194. Resistance furnaces. SUDCHEMIE A.G. 23 March, 1967 [25 March, 1966; 1 June, 1966; 10 June, 1966], No. 13733/67. Heading H5H. A direct resistance melting furnace comprises coaxial pipes 11, 12, e.g. of Pt or Pt-Rh alloy, connected to respective electric conduits 29, 20 at their upper ends and joined at their lower ends, the charge to be melted being fed into the annular space between the pipes. Pipe 12 is fixed by a collar 15 connected thereto by screws 17, and pipe 11 is fixed by an external screw collar 22 and an internal bolt 24 the threaded end 25 of which is tightened against collar 22 by a nut 26. The collars 15, 22 are of, e.g. chrome, nickel, steel, and mount the conduits 20, 29. Inner and outer walls of collars 15, 22 respectively define a feed funnel for the charge, said charge leaving the funnel in the form of a charging cone the base of which touches the pipes. Pipe 12 has thermal insulation 31. The inner pipe 11 is substantially cylindrical while the outer pipe 12 has upper and lower cylindrical sections of different diameters interconnected by a downwardly tapering section (see Fig. 1), so that the temperature of pipe 11, where it is contacted by the melt, lies at or above its melting temperature, the part adjacent the cone base having the maximum temperature (1600‹ C.); the temperature of pipe 12 attains the melting temperature (14,000-15,000‹ C.) at its lowest part only and reduces upwardly, but is greater than the sinter temperature at the cone base; the pipe parts surrounding the cone are at or above the sinter temperature; and the temperature of the pipe parts adjacent the fixing collars is below the sinter temperature and is sufficiently low (<600‹ C.) so that no alloy is formed with the collars. Pipe 11 contains thermocouples at the hottest and lowest parts. The low temperature at the collars is achieved in a first embodiment (Fig. 1) by circulating cooling water or steam through a pipe (27) in bolt 24. In a second embodiment, Fig. 2, the coolant pipe 27, 42 has an extension 43 which carries an inner body 45 of a diffuser nozzle 44. The melt from nozzles 14 in strip form is sucked between nozzle parts 45, 49 by warmed cooling gases from conduit 43 passing through holes 48 and an annular slot 47, and by air drawn in through an annular slot 51. This latter air may be warmed air from cooling channels of collar 15. In a third embodiment (Fig. 3) for the production of glass pearls, extension 43 terminates just below nozzles 14, is closed at its lower end, and has holes (62) at the nozzle height for the passage of heated cooling gas, thus forming a blast nozzle. In a fourth embodiment (Fig. 4), e.g. for producing glass lenses, nozzles (14<SP>1</SP>) are at least 2 mm. wide so that the melt runs out by gravity. A collecting funnel (35) and outlet (36) are welded to the lower edge of pipe 12 and wrapped with heat insulation. The furnace may be fed with molten material from a conventional furnace.

Title: Improvements in methods of and apparatus for treating textile materials
Inventor: WILFORD ERNEST
IPC: D06B3/20
Filed: 1962-04-10
Abstract: 960,505. Textile treating apparatus. BRADFORD DYERS' ASSOCIATION Ltd. April 25, 1963 [April 10,1962], No. 13798/62. Addition to 903, 222. Heading D1L. In treating textile material in the piece with liquid, the material is moved though a bath of the liquid around the periphery of a rotating roller, the liquid is flung centrifugally outwards from the roller against the material and the outwardly flung liquid confined between the roller and the material is allowed to flow outwards from the centre line of the material and to escape at the edges of the material, the material being transversely stretched by this outflow as it moves through the bath. In the apparatus shown material 11 passes over tensioning roller 12, guide roller 16 into tank 2 containing washing liquid 1, under guide roller 17, round agitating roller 7, under guide roller 18, round agitating roller 8, under guide roller 19, and out of the tank via roller 20 and between a pair of driving rollers 21, 22. Agitating, rollers 7, 8 each have four brackets 9 projecting radially at each end, each pair of brackets carrying a satellite roller 10 there-between. The rollers 10 from vanes extending axially along the rollers 7, 8. In operation whilst the rollers 7, 8 are at rest or rotating slowly the material 11 remains in contact with rollers 10 as shown in full lines. As the speed of rotation increases the washing water 1 is picked up and thrown outwards centrifugally against the underside of material 11 such that the latter takes the path indicated in chain dotted line 11a. The water escapes sideways along the space between the material 11 and the rollers 7, 8 so that transverse currents are set up. As an alternative the material 11 may be taken around the underside of roller 8 as shown at 11b so that the material is treated from both sides. A perforated water supply pipe 23 is positioned just above the material 11 between roller 20 and the nip of rollers 21, 22 and a suction pipe 24 is positioned on the underside of material 11. A steam ejector draws water from tank 3 and the mixture is fed to pipe 23 and sprayed over the surface of the material 11 after it has left tank 2. The suction in pipe 24 is also caused by a steam ejector and this suction extracts excess liquid from the material 11 which liquid is returned via pipe 31 into the bottom of tank 2. The tank 2 is connected to a subsidiary tank 3 by a pipe 4 and the water level 5 in these two tanks is kept constant by a float valve 6.

Title: Mountings for engines for aircraft
IPC: B64D27/04
Filed: 1945-06-04
Abstract: 602,256. Aircraft engine mountings. LORD MANUFACTURING CO. June 4, 1945, No. 13983. Convention date, May 19, 1944. [Class 4] [Also in Group XXXII] An aircraft engine mounting element includes a supporting member comprising a housing and a supported member comprising a core within the housing, the members being movable relatively to each other against the action of resilient means in one direction in response to engine vibrations and in a transverse direction in response to propeller thrust, and is fitted with a friction damper having parts associated with the members sliding against each other in response to engine vibrations and moving apart in response to propeller thrust to relieve the damping. As shown, the power plant is supported from the mounting ring 13, Fig. 2, by a series of elements arranged in pairs ab, cd and ef, the axes of the elements converging to a point on the longitudinal axis of the engine adjacent the centre of gravity. Each element comprises an outer housing 15, Fig. 4, secured to the ring, and an inner core having a stem 19 secured to a bracket 20 on the engine by a nut 19a, the housing being closed, after insertion of the core, by a screwed cover-plate 17. The core, Fig. 5, consists of resilient soft rubber members 21, 22 shaped as shown when unloaded and vulcanized to opposite sides of a head 119 formed on the stem and to plates 21a, 22a fitting respectively into a recess in the bottom of the housing 15 and against the inner surface of the cover 17. The members 21, 22 are formed with recesses 21d, 22d and their elasticity is such as to allow relatively free radial movement of the core head. The latter is eccentrically positioned in relation to the plate 22a so that under load it will assume a central position in the housing 15. The plate 21a and housing are formed with corresponding apertures for the reception of a locating pin to ensure correct assembly of the elements. The cover 17 is screwed up sufficiently to place the elements 21, 22 under initial compression so that their circumferential walls are slightly bulged. Under excessive loads, the bulged walls engage the frusto-conical and cylindrical parts 115 and 116, Fig. 4, of the wall of the housing 15 and exert a scrubbing action to limit movement of the power plant. To damp out vibrations, of large amplitude at idling speeds, the elements e, f are fitted with friction dampers, Fig. 9, each of which comprises an annular brake lining 30, riveted to a plate 31 carried by a collar 32, and a dish-shaped spring 33 secured in position by a circumferential channel strip 34. The damper is assembled with the collar 32 fitting into a recess in the bracket 20 and the lining engaging the outer face of the cover 17, the spring 33 resting against the rim of the bracket 20 and being put under compression by screwing up the nut 19a. At higher speeds, the compression of the rubber members 21, 22 to accommodate the engine thrust is sufficient to relieve the compression of the spring and render the damper inoperative.

Title: Improvements in electric cables
IPC: H01B11/12
Filed: 1927-05-25
Abstract: 296,114. Beatty, W. E., (Bell Telephone Laboratories, Inc.). May 25, 1927. Loading or otherwise modifying circuits to improve transmission. - In a continuously-loaded signalling cable having greater inductance in some sections than in others, the capacitance of these sections is also increased in order that the characteristic impedance may remain constant, to avoid increased attenuation. The invention is described as applied to a submarine telephone (or telegraph) cable. Near the ends of the cable the inductance is reduced by the use of lighter loading; the capacitance is correspondingly increased (1) by increasing the thickness of the insulation where the cable goes rapidly into deep water, or (2) by using insulation, such as paper of lower specific inductive capacity where shallow water extends for a considerable distance from the shore. (1) The loading 11 on the central conductor 10 of permalloy at the ends of the cable is lighter than at the midsection 12, Fig. 1, and the diameter of the guttapercha 13 is increased at the ends accordingly. (2) Lighter loading 21 replaces the heavy loading 22 and paper insulation 23 replaces the guttapercha 24, the diameter of the insulation remaining substantially the same. Lead sheathing 25 is used. In a modification of (1) the thickness of insulation is varied by changing the diameter of the central conductor and its loading. In a modfication of (2) a return conductor is positioned within the lead sheath at the end sections for a distance just beyond the paper insulation and is then continued outside the sheath. The Specification discusses the theory of attenuation. Specifications 201,931; 218,261, [Class 40 (iii), Telegraphs, Electric], and 280,449 are referred to.

Abstract: 919,924. Welding by pressure. CROMPTON PARKINSON Ltd. April 18, 1961 [April 27, 1960], No. 14008/61. Addition to 764,764. Class 83 (4). In electric arc stud welding apparatus including a tool having a single solenoid coil connected in series with the welding circuit so as to be energized to retract a stud against the effect of a spring as soon as the circuit is completed and including a contactor for de-energizing the coil after the retraction of the stud, means are provided for switching a resistance in series with the solenoid simultaneously with the closing of the contactor, the contactor short-circuiting the combination of the solenoid and series resistance. The apparatus is supplied from a D.C. source 4 and the closing of a switch PB causes energization of a time delay alloy TD and of a control relay CR. Relay CR closes its contacts CR1 to by-pass the button PB and also closes contacts CR2 to complete a circuit through the lifting solenoid 1, normally closed contacts C2 of a contactor C, the stud 2 and workpiece 3. The stud is then retracted to strike a pilot arc, the intensity of which is limited by the solenoid 1 and a choke 5. The relay CR closes its contacts CR3 to energize the contactor C which closes its contacts C1 to short-circuit the coil 1 and choke 5 and simultaneously opens its contacts C2 to bring a variable resistance 6 into series with the coil 1. The rate of decay of the energy in the coil 1 is controlled by the resistance 6. Finally the relay TD opens its contacts TD 1 to de-energize relay CR. The welding tool may be as described in the parent Specification.
