Title: Improvements in or relating to railway vehicle bogies
IPC: B61F5/48
Filed: 1935-04-15
Abstract: 439,614. Railway - vehicle bogies. SCHWEIZERISCHE INDUSTRIE GES., Neuhausen, Schaffhausen, Switzerland. April 15, 1935, No. 11599. Convention date, April 17, 1934. [Class 103 (vi)] [See also Group XXXI] The body or underframe K of a railway vehicle is supported at each end upon a bogie comprising two radiating axles 3, 4 mounted respectively in separate frames 1, 5 which are pivotally connected at a point 8 between the axles, the body being directly supported on the frame 1 by a centre pivot 2, and the. frame 5 being capable of swivelling with respect to the body about a pivot 6, disposed outside the axles. In the construction shown the forward or outer axle 3 is driven by a motor M, and the pivot 6 is capable of sliding in longitudinal guides centrally disposed on the frame 5. The effect on a curve is that the natural displacement of the axle 4 relative to centre line of the vehicle causes a swivelling movement of the frame 5 about the pivot 6 as shown in Fig. 2, and the consequent lateral displacement of the pivot 8 effects a correct steering movement of the driven axle 3.

Abstract: 496,634. Wireless receiving - apparatus ; aerials. HUBER, E. April 14, 1938, No. 11612. Convention date, April 16, 1937. [Class 40 (v)] In a receiver having a frame aerial, the winding of the aerial, the leads from the aerial to the receiver, and at least the input stage of the receiver are enclosed within an electrostatic screen, the screening around the aerial being interrupted at one point but being effectively continuous electrostatically. The frame windings 11, coupling conductors 19, 20 and the first stage of the receiver are screened respectively by the aerial tube 12, screening means 27, and the casing 2. The screening means 27 is conductively connected to the casing 2 at the point 28 and to the tube 12 by means of the bridge 29, the metal coating of the rotatable lead 5, and the bridge 30. The ends of the tube 12 are insulated from the head 5 by the dielectric sleeves 31 to prevent the tube forming a short circuit turn. Alternatively the tube may be directly connected to the head 5 and split at its upper mid point. The two halves overlap and are insulated from one another to provide uninterrupted screening, Fig. 2. The head 5 is mounted on the mast 1 by ball-bearings and may be rotated by wormgear 8.

Title: Improvements in or relating to apparatus for heating liquids by electricity
IPC: F24H1/10
Filed: 1928-04-21
Abstract: 314,165. Foy, F. April 21, 1928. Electric hot-plates; heating by electricity.-A one or more heating elements p is arranged in a hollow-walled shell d and a narrow spiral or zigzag passage through which the liquid flows is formed between the shell and the tube by corrugations c on the shell or .tube. Alternatively the passages is formed by soldering a strip to the shell or tube. A sleeve l brazed on the tube j screws into a flange g carrying the shell d and is held in position by a, lock-nut n. The flange g may be soldered to the vessel r. The space between the walls of the shell d may be filled with air or other gas at any pressure. A number of such heaters may be enclosed in a further hollowwalled shell open at the top and bottom for passage of liquid. The heating element, Fig. 8, comprises insulating blocks t, spigoted into one another and held together by a central bolt y, resistance spirals u being threaded through straight or spiral grooves in the blocks. Longitudinal movement of the spirals is prevented by discs s having a flat side and arranged in recesses on the blocks t, or by plates shaped as in Figs. 12, 13 and arranged between adjacent blocks. The plate in Fig. 12 is given a part turn after the spirals are threaded into position. The terminals z<1>, 2 are secured to plates z, 1 separated by insulation 5. The plate z is connected to the top ends of the resistance spirals and has a central hexagonal hole fitting over a corresponding spigot on the block t. The plate 1 has an aperture and slot to allow the bolt y and terminal z<1> to pass therethrough and makes electrical connection with the lower ends of the resistance spirals through the medium of the bolt y. The insulating disc 5 is cut so that a part 6 can be turned up therefrom to prevent arcing between the terminal z and plate 1. The apparatus, Fig. 9, is controlled by a thermostat 14 protected for a portion of its length from contact with the liquid by a casing 15 filled with air or other gas at any pressure.

Title: Improvements in or relating to electromagnetic time-limit devices
IPC: H01H50/86
Filed: 1934-04-20
Abstract: 428,729. Electromagnets. WESTING- HOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, Pennsylvania, U.S.A.- (Assignees of Schaelchlin, W. ; 305, Woodside Road, Wilkinsburg, and Frisch, E. ; 7143, Thomas Boulevard, Pittsburg, both in Pennsylvania, U.S.A.) April 20, 1934, No. 11949. Convention date, May 11, 1933. [Class 35] [See also Group XXXVII] In an electromagnetic time-limit device comprising a core member, a movablymounted armature and a coil for magnetizing the core member, in order tc increase the timelimit range over which the device is capable of being preset for operation there are provided means for decreasing the rate of decay of the magnetic flux when the coil is de-energized and also means for dissipating the residual magnetic flux. As shown in the Figure the core 31 carries an operating winding 11 and an opposing neutralizing winding 5 a heavy ring 23 of good conducting material such as copper, silver &c., being placed between the core and the inner coil. The armature 34 is formed at its upper end with a knife-edge portion 37 adapted to pivot between the end of the yoke 33 and a plate 35 attached thereto, a bent-up portion of the latter limiting the outward movement of the armature under the action of the adjustable retractive spring 45. The armature carries a contact 26 whch is brought into engagement with a contact 27 a predetermined time interval after the circuit of the operating coil is broken. This time lag is controlled by the adjustment of the retractive spring 45 and the range over which the time limit can be adjusted is increased by the action of the ring 23 in retarding the decay of flux in the core and of the winding 5 in neutralizing the remanent magnetism. The magnetizing force of the winding 5 is made very small relatively to that of the operating winding 11 so that it has no appreciable neutralizing value until the magnetic flux has fallen to a low value. Theoretical considerations underlying this action and operating curves are given in the Specification.

Abstract: 142,821. Hemphill Co., (Assignees of Bosworth, G. P.). Oct. 10, 1918, [Convention date]. Knitting.-A machine-knitted glove or mitten is made from two selvedged blanks secured together at the edges in any suitable manner as by stitching or seaming. The tnumb may be made separately from or integrally with the front part Assuming that the glove is to be made on a circular knitting- m a c h i n e with independent needles, reciprocating Knitting may be begun at the base of the wrist on the breadth 1-2 either at the front or back, and the wrist part may be fashioned or be subsequently shaped by cutting and seaming. Preferauly the front blank is knitted first, and the finger fronts are knitted integral with the glove front beginning with the little finger. The finger backs are knitted integral with the glove back beginning with the first finger. The line 3-4 at the base of the thumb having been reached, preferably all the needles are elevated while retaining their loops and immediately afterwards the thumb needles are restored to action to knit a strip 5, 6, 7, 8 which may be fashioned or not. Knitting is then continued on the expanse 9-10 until a line 12-13 at the bases of the fingers is reached. The finger fronts are knitted in succession, beginning with the little finger. At the completion of the selvedged strip 15, which may be fashioned or not, some of the needles are left in action and others may be brought into action to increase the breadth of the strip 20 forming the front of the third finger and thereby to form a gusset or lap between the third and the little finger. The finger strips 20, 24, and 27 are knitted in succession in a similar manner to the strip 15 and the work is finally run off the needles. The blank for the back of the hand is preferably formed in the same way as for the front, except that no thumb strip is required.

Abstract: 777,519. Electronic counting-apparatus; pattern-movement stepping registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 28, 1955 [May 17, 1954], No. 12278/53. Class 106 (1). [Also in Group XXXIX] In a stepping circuit for a shifting register or counter comprising a series of bi-stable magnetic cores each embraced by input, output and drive windings, means for pulsing together the drive windings of alternate cores, and a transfer circuit including a unidirectional conducting device coupling the output winding of each core with the input winding of the succeeding core, a single impedance element is in series with and common to all the transfer circuits. As shown, the cores A, B, C, D ... have drive windings 16a, 16c and 16b, 16d connected via lines 17 and 18 respectively to pulse generators 19 and 20 alternately operative under control of flip-flop 21 which receives actuating pulses over lead 22. The transfer circuits comprises diodes 2, 5, 8 ... , the input and output windings, and a common resistor R provided to prevent back transfer. If, e.g. core B is in the " 1 " stable state, the next drive pulse through 16b will restore it to the " 0 " state, thus producing a large pulse in output winding 4 in a direction to pass diode 5 and energize input winding 6 of core C to switch the latter to the " 1 " state. The drop in voltage across R due to this current flow in the transfer circuit between cores B and C cancels the pulse induced by the drive pulse in input winding 3, so that no current flows in the transfer circuit, comprising diode 2, between cores A and B. The value of resistance R may be chosen so that the voltage drop produced by current flow through more than one transfer circuit is too great, whereby only a single " 1 " may be propagated; the apparatus may then operate as a counting ring which responds to the pulses on lead 22.

Title: Manufacture of calcium carbide and a shaft furnace for use in such manufacture
IPC: C01B32/942
Filed: 1955-04-28
Abstract: In the production of calcium carbide in a shaft furnace from lime or limestone and carbon, e.g. in the form of coke, the furnace is charged such that, in a horizontal plane immediately above the tuyere mouths of CaO concentration of the charge increases continuously from the walls to the centre of the furnace.  The proportion of lime to carbon may increase slowly from the furnace wall to a point at some distance beyond the tuyere mouths and then increase rapidly up to the central region where the concentration of CaO may be 85 per cent. The differential concentration may be produced by means of a special charging installation whereby the charge may be supplied to the furnace along the wall, along the centre, or along an intermediate region as desired (Fig. 3. not shown), or by passing a mixture of coke and lime in which the particles of lime are at least twice as small as the coke particles through a centrally arranged vertical feed pipe (Fig. 4, not shown).  Specification 727,497 is referred to.
