Title: Improvements in or relating to bogie-frame constructions of rail vehicles
IPC: B61F3/06
Filed: 1950-12-28
Abstract: 681,467. Rail-vehicle undercarriages. SCHWEIZERISCHE LOKOMOTIV - UND MASCHINENFABRIK. Dec. 28, 1950 [Feb. 8, 1950], No. 31463/50. Class 103 (vi). A rail vehicle has a bogie comprising a frame 1, cross-beams 17, and cross-bars 12 which interconnect the ends of springs 11 and are suspended by links 13 from the bogie girders 14. The body 8, Fig. 3, is supported by its side girders 9 and slide-plates 10 from the bolster, and body transverse beams 21 disposed immediately fore- and-aft of the bogie centre portion are connected to the bogie beams 17 by two pins 16 which serve to transmit the traction and braking forces but not the bearing forces. The pins 16 are secured to the beams 17, and through spherical mountings 18 and slide-blocks 19 engage transverse slots 20 of the body crossbeams 21, the pins being able to move vertically within the bushes 18 within range of the bolster spring play. The slide-blocks 19, Fig. 2, are so arranged to the slots 20 that at any time only one of the pins 16 is active in transmitting the driving forces. For such purpose the blocks 19 are spaced a distance " a " from the sides of the slots 20. In this arrangement the driving forces always act on a point to the rear of the bogie centre, and the braking forces act on a point in front of the bogie centre. In a modification, the body transverse beams are disposed above the bogie cross-beam and the pins are secured to the body beams. In this embodiment the clearances " a " are situated between the sliding blocks and the bogie beams on the side nearest to the bogie centre. In another modification, the guide slots are curved.

Title: Improvements in or relating to flame cutting machines
IPC: F23D14/46
Filed: 1925-12-14
Abstract: 265,734. Hancock, L. J. Dec. 14, 1925. Blowpipe burners.-In a flame cutting machine of the type described in Specification 226,846, the valve controlling the supply of oxygen to the cutting jet is operated by a flexible connection from a part remote therefrom. A cable 2, secured at one end to a lever 5 which through a rod 8 opens the spring-controlled valve 9, passes through a flexible tube 3 and is operated by a lever 14. The lever 14, which may be arranged to stop and catch at several positions, at the same time operates the switch for controlling the traversing motor so that cutting starts, after preheating, immediately an increased supply of oxygen is supplied to the nozzle. In a modification a similar valve may be arranged above the valve shown and operated by the lever 5 before the valve 9 so that oxygen is supplied through a separate passage for preheating purposes. This passage may be provided with a fine adjustment valve. In a further modification the lever 5 is operated by an electromagnet. Separate and simultaneously operated levers may be used to operate the valve and motor-control switch.

Oct. 17, 1929, No. 31588. Convention date, Oct. 22, 1928. [Class 38 (iv).] In supplying from an alternating current circuit a consuming device, such as an X-ray tube, utilizing only half the e.m.f. wave a device is provided for absorbingenergy from the unused half of the wave so that the amplitude of that half of the e.m.f. wave may be made equal to or less than that of the useful halfwave, and the insulation requirements of the consuming device and its circuits are therefore reduced. The power factor is also improved. A transformer 73 furnishing high tension current from a secondary winding 74 to the anode circuit of an X-ray tube 67 has a further secondary winding 75 supplying a circuit comprising resistance or inductance and containing a synchronously-driven commutator 119, a two electrode valve or the equivalent. The cathode of the tube may be heated by a transformer 70 regulated by resistance 108 in its primary circuit and the primary of the transformer 73 may be supplied from a variable autotransformer 78 through a starting resistance 91. The resistance in the energy absorbing circuit may be in two portions 93, 100 each variable in conformity with the variations of anode volts and cathode current respectively so as to maintain the desired control of the unused portion of the voltage applied to the tube. Thus switches 82, 103 simultaneously control the tube and absorption circuits.

Title: Improvements in and relating to machines for bending and shaping wire and the like material
IPC: B21F1/00
Filed: 1922-11-20
Abstract: 210,565. British Thomson-Houston Co., Ltd., and Kingwell, K. F. Nov. 20,1922. Making metal fabrics; corrugating; formers.-A machine for bending and shaping wire into the form of grid such as is used in making electrical resistances comprises a pivoted arm which folds the wire on a series of formers mounted on an endless chain, automatic means being provided to bring the formers successively into position. The pivoted arm 1 carrying a guide 49 fitted with wire straightening-rollers, is provided with curved arms 50 (Fig. 7) to prevent too sharp bending of the wire and is oscillated from a toothed segment on an arm 4 which is operated through a connecting rod 11 from a crank disc on a vertical shaft 16 driven from the main shaft 14. The wire is passed from a drum to the guide 49 over a pulley 52 which is counterweighted to maintain the tension of the wire during the swinging of the arm 1. The formers each comprise a formed hardened top 17 secured to a base 18 which is adapted to slide in ways on the table 26 and which carries a lower plate 19 having pins 20 which engage the links of an endless chain running over pulleys 21. A jockey pulley 24 is provided to keep the operative portion of the chain horizontal. The formers are lifted successively by means of levers 36 carrying spring pins and actuated by cams on a cross shaft 31. A ram 39 actuated through toggle levers 40 and bell-crank lever 44 from a cam 47 on the cross-shaft serves to push the formers into position beneath a spring pressed plate 29 and to move the chain through one link to bring the next former into position. The lifting and positioning of the formers are both effected while the wire guide is in one of its extreme positions. After the formers have passed beyond the pressure plate 29 the inclined portion of the chain causes their gradual withdrawal from the formed grid which passes off over guides into a receptacle, the formers being recessed to allow the removal of the grid without distortion.

Title: Improvements in inverter networks
IPC: H02P27/04
Filed: 1963-08-12
Abstract: 1,056,874. Inverting; control of A.C. motors. M. ETTER. Aug. 12, 1963 [Aug. 13, 1962], No. 31719/63. Headings H2F and H2J. In a polyphase inverter comprising a bridge of controlled rectifiers 5, 6 fed from a D.C. supply a, b, and feeding a motor M, control means are provided so that the current waveform attains a desired shape, preferably a sinusoid. With a rectifier 5 conducting a median point 8 is at the positive supply potential, and with a rectifier 6 conducting it is at earth; also diodes 3 and 4 carry provide for the continuance of current when a rectifier shuts off. It is therefore possible to have any desired mean potential for the point 8. Inductors and diodes 44-47 are provided to take up current surges on switching. The switching off of a rectifier is effected by firing two series rectifiers 5, 6, together so as to charge a resonant circuit 50, 51 or 52. The discharge of this circuit through the rectifiers shuts these off. Firing signals are derived from an oscillator 33 (at, say, 3000 c/s.) through a ring-counter 54 giving pulse signals Bi, Bj, Bk, at a signal frequency of 1000 c/s. These signals (Fig. 2d) pass to control units 55, 56, 47, which route each signal to either rectifier 5 (Fig. 2e) or rectifier 6 (Fig. 2f) in order to control the current so that this tends to follow a desired sinusoidal waveform. This routing is effected as follows:- The actual phase current I r  (Fig. 2a) is compared with the current a of a sinusoidal source 61 of 1000 c/s. in saturable cores 58, 59, 60. Whenever these current waveforms cross a short pulse is produced (due to reversal of the magnetization) whose sign depends on whether I r  is becoming larger ( + ve) or smaller ( - ve) than a (Fig 2b). These short pulses are applied to the units 55, 56, 57, wherein further pulses are produced which are started by a positive short pulse and terminated by the next negative short pulse (Fig. 2c). If the pulses Bi from the ring counter arrive during the presence of a long pulse it is routed to rectifier 6; if, however it arrives during an interval between pulses it goes to rectifier 5. The routing circuitry comprises a transistor arrangement (Fig. 3, not shown).

The starting 3a -acyloxy - 16a ,17a  - epoxy - 20 - ethylenedioxy - 5b -pregn-9(11)-ene may be obtained by protecting a 3a -acyloxy-16a ,17a -epoxy-5b -pregna-11,20-dione by ketalation to form a 20-ketal, reducing the latter with simultaneous saponification to form 16a ,17a -epoxy-20-ethylenedioxy - 3a ,11b  - dihydroxy - 5b  - pregnane by means of an alkali metal borohydride, esterifying the latter to form the corresponding 3a -acyloxy - 16a ,17a  - epoxy - 20 - ethylenedioxy - 11b -hydroxy-5b -pregnane followed by dehydration to obtain the desired 3a -acyloxy-16a ,17a -epoxy - 20 - ethylenedioxy - 5b  - pregn - 9(11) - ene. The 3-hydroxy compound may be oxidized to obtain a 3-keto compound while unsaturation in 1 and 4 positions may be introduced by dibromination and dehydrobromination. A 21-acyloxy group may be introduced by treatment with iodine follow by an alkali metal acylate.  The products are useful in the preparation of betamethasone.

Title: Machine for squaring folded box blanks
IPC: B31B5/74
Filed: 1957-10-14
Abstract: 832,733. Apparatus for making boxes. UNIVERSAL CORRUGATED BOX MACHINERY CORPORATION. Oct. 14, 1957 [Nov. 7, 1956], No. 32068/57. Class 18. [Also in Group XVI] When a box blank A, B, C, D, Fig. 18, has been folded so that a glued flap 253 underlies the panel A, the folded blank is squared by an apparatus comprising means 16, 71, Fig. 2, for advancing the folded blank through a channel 112, 112 which, at least at the outlet end 121, engages the side edges of the advancing box blank to square it before the glue has set. As shown, Figs. 2 and 5, there is a centre belt conveyer comprising an upper belt 42 and a lower belt 68 between which the folded blank is gripped and fed forwards, and two outer conveyers each comprising an upper belt 92 and a lower belt 98, Fig. 2, between which the flaps 252 of each panel A, B, C, D, are gripped and fed forward, all three conveyers moving at the same speed. The channel 112, 112 comprises two endless belts 153 each passing over end pulleys 121, 152, Fig. 9, and over intermediate idle rollers 115, the pulleys and rollers being spaced apart by a beam 113. As the belts 153 are rotated, cam action oscillates each beam 113 about the axis 119 of its associated pulley 121, such oscillation causing the belts 153 to tap the outer edges of the flaps 252. Thus, when a box blank reaches the pulleys 121, Fig. 2, which are spaced by a distance equal to the width of the box blank, the adjacent edges of panels A and D of the blank will have been aligned with each other. Shingling conveyers. As the box blanks pass out from the center conveyer belts 42, 68, Fig. 5, they drop onto a pair of shingling conveyers 174, Fig. 2, each comprising upper and lower belts 204, 212, Fig. 5, moving at a speed less than that of the center conveyer belts 42, 68, so that a shingling effect is provided. Weighted rollers 194, 203 and a pivotally mounted pulley 191, act on the panels A to hold them against the glued flaps 253. Idle rollers 221, Fig. 2, retain the box blank in squared condition whilst passing through the shingling conveyer 174. The shingled box blanks then move onto a conveyer belt 235 passing under weighted rollers 238 to give the glued joints time to dry. When the box blanks have panels A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>, D<SP>1</SP>, Fig. 20, with flaps 270, 272, of different widths, a deflector member 275, Fig. 17, is associated with each outer conveyer 71, the deflector member having a first set of wheels 282 engaging the wider flaps 272 to deflect them downwardly so that they may be tapped by the belts 153, and a second set of wheels 285 engaging the narrower flaps 270 and urging them inwardly. Various sized boxes. To accommodate various sized box blanks, adjusting screws extend across the apparatus and into the various conveyers, channel members, &c., so that these can be displaced to various positions.
