Title: Method of manufacturing squirrel cage rotor winding assemblies
Inventor: BEGOVICH CHARLES
IPC: H02K15/00
Filed: 1971-04-19
Abstract: 1281314 Making squirrel cage rotors; forging; extruding GENERAL MOTORS CORP 19 April 1971 [7 April 1970 (2)] 25237/71 Headings B3A B3H and B3P A metal slug 28 e.g. of aluminium or copper is extruded in a press 34 through slots 16 in a rotor core 12 to form the rotor bars (20) of a squirrel cage winding assembly (18) of a rotor (10), Fig. 1 (not shown). The core lamination stack is pressed into a mounting block 38, which is assembled with a die plate 36, guide block 42 and mandrel 40. The extrusion chamber 54 so formed has a radial width greater than or equal to the radial depth of the slots 16. A piston 62 is placed on an aluminium slug and a ram 60 is lowered on to the piston. The press 34 is heated to 1000-1150‹ F., the temperature being such that the temperature rise due to extrusion does not cause melting of the aluminium. The extruded aluminium passes into an annular cavity 64 to form an end ring (22) and sufficient material is left in the chamber 54 to form an end ring (24), Fig. 1. The end rings may be formed to the required shape in the press 34 or other dies may be used to press them to their final shape. In an alternative form of press, Figs. 12-14 (not shown) slugs (232), (234) are positioned on either side of the core laminations and extruded into the core slots (216). The extruded material fills the slots and a metallurgical bond (298) of the material of the slugs is formed at the slot centres, Fig. 14.

Title: Improvements in or relating to gas fires
Inventor: CARPENTER BERNARD LEONARD
IPC: F23K5/00
Filed: 1962-07-02
Abstract: 962,187. Incandescent gas fires. R. & A. MAIN Ltd. April 26, 1963 [July 2, 1962], No. 25339/62. Heading F4W. A gas fire of the kind comprising a number of radiants of a refractory material supported above the jets of a multi-orifice burner 10, is characterized in that different burner orifices or different groups of orifices are supplied with gas by at least three separate passages 11, 12, 13, feeding for example, as in the embodiment shown in Fig. 2, the burner orifices 1 and 5, 2 and 4, and 3 respectively. By providing gas to various combinations of the passages, by means of a multiway cock (Fig. 6), the number of radiants which are incandescent may be varied from 1 to 5. The cock body 23, which is fitted to the righthand end of the burner 10, has a taper bore 24, the smaller end of which is connected to a gas supply. The ports 26, 27, 28 extend through the cock body, and are connected to the passages 12, 11, 13, respectively. The rotatable valve (Fig. 7), which is positioned within the cock body 23, comprises a taper plug 6 having a passage 39, extending up from the smaller end. Various ports and grooves (Figs. 9, 10, 11, not shown), are cut in the said plug such that, when the plug is in various set positions relative to the cock body, gas is permitted to flow from the passage 39 to certain combinations of the ports 26, 27, 28; and hence to certain combinations of the passages 11, 12, 13. Thus with the plug in the first position relative to the cock body gas is supplied to all orifices 1 to 5; on rotation of the plug to the second position gas is supplied to orifices 1, 2, 4, 5; whilst on rotation to the third position gas is supplied to orifices 1, 3, 5 &c. By means of bleeder holes 41, 42 (Fig. 5, not shown), a minimum supply of gas is always fed to all orifices to support a stable pilot flame, so that on changing the valve position a full supply of gas may be fed to different orifices without ensuing noise. Ignition of the gas is obtained by turning the plug fully anti-clockwise from the off position past the last stable position, in which position gas flows to all orifices, and which brings a port 47 (Fig. 12, not shown), into register with a port 48 in the cock body, through which gas feeds to a glowing filament, itself operated by the lattermost movement of the plug, ignition thus occurring. Reflectors may be fitted to the fire, flanking the outermost radiants.

Filed: 1951-10-30
Abstract: 721,223. Electric tests. NATIONAL COAL BOARD. Jan. 30, 1953 [Oct. 30, 1951], No. 25350/51. Class 37. Apparatus for measuring the moisture content of granular material, e.g. pulverized coal, having relatively high conductivity by making the material affect the capacity of a condenser forming one arm of a bridge circuit is characterised in that the frequency of the bridge supply is greater than 10 mc/s., and the unbalance current may be fed to a phase-sensitive detector so that only the reactive current is measured. As shown (Fig. 3), the bridge comprises two coils L1, L2 which are the secondary windings of a high-frequency transformer fed from an oscillator HFO a standard prefixed capacitor C1 and a sampling capacitor C2. The unbalance current produced when the material to be tested flows through or past the capacitor C2 is fed via an amplifier VA to a detector VD for indication on a meter I, a reference signal being obtained direct from the oscillator HFO to make the detector VD phase sensitive. For making spot tests the capacitor C1 may be variable and have a calibrated dial, a series or parallel variable resistor (not shown) being added for phase adjustment if required. The output of the detector VD may be used to control the degree of moisture content of the material. Capacitor construction.-For making continuous tests on a flow of material, a main plate 10 (Figs. 4, 5) supports two pillars 14, 15 on which is mounted a bed-plate 16 covered by a rubber pad 17. One electrode is the lid 12, and the other electrode is a metal strip 18 assembled between two insulating plates 19, 20 and pressed against the lid 12. Granular material passing along the surface of the lid 12 enters the fringe field of the capactor and affects its impedance.

Title: Method and apparatus for continuously reacting and/or mixing liquid and solid components
IPC: B01J19/00
Filed: 1957-08-12
Abstract: 840,349. Mixing solids with liquids. BALLESTRA, M. Aug. 12, 1957 [Sept. 4, 1956], No. 25350/57. Class 86 In an apparatus for mixing a powdered or granular solid with a liquid, which may be viscous, the solid is fed into contact with the liquid as the latter issues from an atomizing device. In the form described, the viscous liquid is delivered from a container 1 to an atomizing nozzle 4, located in a mixing chamber 3. A fan 6 withdraws air from this chamber and picks up powdered material received through a shoot 14 and feeds it to a cyclone device 16, which discharges into the area surrounding the nozzle 4. In a similar manner a second component of the mixture may be fed in through a shoot 26, whence a second air stream carries it to another cyclone 28, the outlet of which is concentric with that of the first. The chamber 3 is made of sufficient height for any chemical reaction to be complete before the product reaches the outlet 5. If it is not desired to circulate the air continuously, the air exhausted by the fan 6 is passed to a duct separator 37 so. that unused powdered material can 'be collected for re-use. Butterfly valves such as 18, 30 control the flow of air from the fan while others, 19, 31, control the admission of additional air.

Abstract: 749,651. Washing gases. CHEMIEBAU DR. A. ZIEREN GES. Sept. 15, 1953 [Sept. 15,1952; Nov. 6, 1952; Nov. 6, 1952; Nov.6, 1952; Nov. 6, 1952], No. 25446/53. Class 55(2). [Also in Group XIII] Finely divided solid particles, liquid mists, &c. are separated from gases by passage through one or more beds of small irregular or regular bodies at such a speed that a mainly turbulent flow is produced within the interspaces formed by the bodies as distinct from a laminar flow characteristic of lower velocities. In these conditions of cross section of flow path and velocity of flow, individual streams disappear and gas particles freely intermix with the formation of eddies ; the Reynolds number reaches a critical value of over 100. The pressure drop through the bed should not exceed a head of 180 m.m. of water and the rate of flow should be at least 1750 m. per hour reduced to standard conditions. Coke, gravel, balls, prisms, rings, star and saddle-shaped bodies, &c. may be employed for the bed which should consist of more than three layers of the bodies. Liquid which may be heated or cooled may be sprayed on the bed during the treatment. This may comprise recirculated liquid or water, dilute acid or a salt solution. A number of beds may be used with the size of the bodies decreasing from stage to stage, in each of which several small separate beds may be used in parallel. The process may be applied to the catalytic production of sulphuric acid and the separation of other acid mists as of hydrochloric, hydrofluoric, silicofluoric silicic acid, or organic mists such as of coal tar oil.

Title: Variable-speed and reversing gearing suitable for motor-vehicles
IPC: F16H15/20
Filed: 1921-09-26
Abstract: 169,463. Castel de Courval, G. Sept. 24,1920, [Convention date]. Variable - s p e e d gearing comprises an epicyclic train controlled by a friction cone coacting with a movable roller or pinion. A friction cone 8, Fig. 2, is splined on a driving- shaft 9, which drives through bevel-gearing 23, Fig. 3, the carrier 22 of planet pinions 21. The annulus 20 of the epicyclic train is geared through a jointed shaft 18 to a spline shaft 16 upon which the movable roller 15 slides under the control of, say, the driver of a vehicle. A sun gear 27 is the driven element, and this may be connected through a balance gear 26 to a divided axle 25. When the roller 15 is near the small end of the cone 8, the element 27 is driven at top speed. In the configuration shown, the element 27 is hardly driven at all. When the roller 15 is opposite a gap 14 in the cone, the drive ceases. The drive may be stopped at any time by sliding the cone on its shaft towards its thick end. When the roller 15 engages an ,extension 28 of the cone, the element 27 is driven reversely. In a, modification, the planet-carrier is geared to the roller spindle, so that some of the actual drive passes through the roller. In a modification-shown in Fig. 6, the shifting of the roller is done by the power of the engine, the spindle 16 being tilted to one side or the other to bring it about. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement with toothed gearing instead of the friction gearing. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,272,435. Shuttleless looms. MACHINEFABRIEK L. TE STRAKE N.V. 21 May, 1969 [29 May, 1968], No. 25990/69. Heading D1E. A weft storage device for a shuttleless loom comprises a weft supply member 2 rotating in a housing 1 having associated therewith at least one weft storage tube 7 or 8 and a weft delivery device 16, e.g. a jet nozzle or weft gupper, the weft being clamped by clamps 26, 28, while the member 2 moves the weft across the entrance of a storage tube 7, 8, to permit a loop of weft to be drawn into the tube, following which the stored weft is introduced into the delivery device 16 by a positioning needle 33. In the jet nozzle loom shown wherein weft is supplied as hairpin loops, the legs of which are fed in succession, storage tubes 7, 8 are formed by flat, transparent hoses and the rotating member 2 has an axial weft supply passage 5 leading to a radially directed outlet 20. Member 2 rotates intermittently in steps of 180‹. At the beginning of a cycle, Fig. 5, and weft thread, held by clamp 26, is carried by the outlet 20 across the entry slot of tube 7 into which it is sucked to form a loop 3. Member 2 then rotates 180‹ to carry the thread, clamped by a second clamp 28, across the entry of tube 28 in which a second loop is formed. Simultaneously positioner 33 descends to move the end of the first loop, which is released by clamp 26, into the jet nozzle 16 for picking by the jet. A ramp 25 on the member 2 causes the end of the loop to ride up on to the end face 22, Fig. 8, so that when the member 2 rotates a further 180‹ the thread issuing therefrom passes under the picked thread held by clamp 28. Clamp 26 moves to position 26' and clamps the thread as soon as opening 20 moves past this position, whereby a new loop starts to form in tube 7. Positioner 33 descends again to move the end of the loop in tube 8 into nozzle 16 for picking, a cutter 27 severing the end adjacÚnt the clamp at 26', and clamp 28 release the inner bight of the hairpin loop. The clamp 26 returns from position 26' to 26 and the cycle repeats. The thread is fed from a package by rollers 4 and the thread collecting while member 2 is stationary may be retained temporarily in a supplementary storage device 3.
