Title: Improvements in and relating to the manufacture of pneumatic tyre covers
IPC: B29D30/06
Filed: 1929-10-23
Abstract: Tyre-covers are shaped and consolidated by heat and pressure, for example in an ordinary vulcanizing mould; they are then removed and vulcanized, or the vulcanization is completed by heating them in water under a pressure higher than that of saturated steam at the vulcanizing temperature.  The water may be kept in motion to ensure equality of temperature, and it may carry in solution substances which increase its density to just below that of the article treated. The pressure may be increased by admitting compressed air to the surface of the water in an autoclave.  The Specification, as open to inspection under Sect. 91 (3) (a) is not limited as to the medium in which the articles are vulcanized, nor as to the pressure employed. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to dynamo-electric machines
IPC: H02K3/12
Filed: 1934-11-09
Abstract: 445,490. Cores and coils for dynamoelectric machines. WESTINGHOUSE ELECTRIC MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Jones, M. F. ; 534, Greendale Avenue, Edgewood, Pennsylvania, U.S.A.) Nov. 9, 1934, No. 32317. Convention date, Nov. 11, 1933. [Class 35] The core of a dynamo-electric machine has winding slots formed with a rectangular bottom portion A, an upper intermediate portion B having the same cross-sectional area but a smaller depth, these two portions each housing the same number of conductors, and a top portion comprising a lower wide part 22 and a neck 21 in line with the lower part having a transverse dimension substantially equal to the transverse dimension of the bottom slot portion. The invention is particularly applicable to railway motors and the object is to improve commutation It is explained in the Specification that the most diffcult conductor to commutate satisfactorily is the lowest one in the slot by reason of its self inductance. It is explained further that if during commutation of one conductor, another conductor in the same slot forms part of a coil which is still short circuited by a commutator brush, damping currents will be set up in this coil and the voltage induced in the conductor in question is reduced. Accordingly it is arranged that the la,st conductor in a slot to be commuted will be as near the top as possible. As shown in Fig. 5, the conductors are rectangular in cross-section and are positioned with their longer dimension b vertical in the lower slot portion and with their shorter dimension a vertical in the upper portion. The upper conductors are introduced edgewise through the neck 21 and rotated through 90‹ in the widened part 22 before placing in position and the slot is closed by an insulating wedge 23. The conductor section is changed, both at the commutator end and at the back end of the armature while keeping the cross-sectional area constant either by forming separate pieces and welding them to the conductors or by drop forging or hot pressing the ends of the conductors. Alternatively, the conductors may be assembled as a unit, the ends flattened, twisted through 90‹ and finally pressed to the required shape, for example as shown in Fig. 47. A conductor in the upper part of a slot is connected to a conductor in the lower part of another slot and the arrangement may be such that for one direction of rotation, the last conductor to commutate will be the lowest in the top group, and for the other direction, the uppermost in the bottom group.

Title: An improved means for cutting textile fabrics and the like
IPC: D06H7/02
Filed: 1945-11-30
Abstract: 610,543. Feeding webs; sheet-delivery apparatus. ASHTON BROS., & CO., Ltd., and BAYES, A. W. Nov. 30, 1945, No. 32356. [Class 100(i)] A textile fabric or the like manufactured in continuous strip form with a ridge or like raised recurring formation in between or forming part of a pattern or other recurring feature, is cut into lengths in predetermined positions in relation to the pattern &c. by a cutter. mounted on - a feeder member slidable over the plane surface of the pattern but adapted to engage the ridge. As shown, fabric is drawn intermittently off a roll 57 by a spool 57b with which a roller 60 carried by an arm 59 co-operates, the pulley being driven by a pawl carried by a sprocket 61 oscillated by a chain 62 carrying a weight on one end and attached at the other end to an arm 63 fixed to a shaft 32. The fabric forms a loop and then passes down a channel 52 and under a weighted drag 55 to a guillotine 29 carried by a reciprocating feedblock 20. A section of the web is pulled forward at each cycle of the machine by the forward edge of a stirrup 21 which is pivoted at 22 to the block 20 and the forward end of which engages a ridge on the fabric to commence the feed at the correct time relative to the guillotine 29; the latter co-operates with one edge of a slot 28 in the block and a guide pin 20c prevents lateral movement of the fabric during severance. During the inward stroke of the block, the stirrup, which is supported by toggles 24 is in the raised position and towards the end of the stroke the toggle pivot engages a stop 26 to collapse the toggles and allow the stirrup to fall. The stirrup is, however, supported by an adjustable bracket 56 projecting from the drag 55 and drops off on to the fabric during the return stroke to engage behind the ridge; the stirrup is subsequently raised by engagement of the toggles with a stop 25 which may be adjustable to vary the position of the cut. The guillotine is oscillated about a pivot by a rod 34 connected to a lever 31 rocked about the shaft 32 by a cam 15 on a shaft 12 carrying also a cam 16 for reciprocating the block 20 through a lever 18 pivoted at 19. On the upward stroke of the guillotine, a finger carried thereby raises the leading end of the fabric clear of the edge of the slot 28. The cut labels are delivered by a belt 38 into a shoot 44 in which they are packed against the action of a resilient member 52 by a cam-actuated pusher 45. The packed labels pass under a guide 51 adapted to restrain them and so provide a space for the next label.

Title: Improvements in magnetic materials
IPC: C21D1/76
Filed: 1929-10-29
Abstract: Magnetic materials, which may be iron or certain specified iron alloys, are subjected to a heat-treatment comprising heating in hydrogen or in a gas containing hydrogen under regulated conditions of temperature and pressure varying from a pressure of at least 10 atmospheres at 800-1000 DEG  C. to at least 1 atmosphere at 1300 DEG -1400 DEG  C., and down to at least about 45 mm. of mercury at between 1400 DEG  C. and melting point.  This heating is followed by cooling quickly through about 900 DEG  C., working if necessary, and reheating at about 880 DEG  C.; or the rapid cooling may be interrupted at about 880 DEG  C. for some time, whereafter no reheating is necessary; or the metal may be cooled slowly under successively increasing gas pressure varying from about 1 atmosphere at 1400 DEG  C. to about 15 atmospheres at 1000 DEG  C.  The heating may be effected by passing alternating current through the metal in a glass cylinder through which hydrogen is passed.  Iron may be melted in hydrogen followed by treatment as above.  The materials treated may be iron purified by means of calcium boride, or iron containing specified proportions of sulphur, alumina, ferrous chloride, silicon, aluminium, magnesium, manganese, molybdenum, ferric oxide, and nickel.  The treated material may be used as cores for relays, transformers, magnetic clutches, diaphragms, inductances and loading material for signalling conductors.  In the last case, after winding tape of the loading material on the conductor, strain may be relieved by heating at about 880 DEG  as referred to above.  Specifications 265,642, [Class 72, Iron &c.] and 342,360 are referred to.

Abstract: 1,245,741. Rectifier assemblies. ENGLISH ELECTRIC CO. Ltd. 16 July, 1968 [18 July, 1967], No. 32843/67. Heading H1K. [Also in Division H2] A rectifier assembly comprises, for each phase, a plurality of pairs of bus-bars each with a plurality of diode rectifiers distributed along their length and connected in parallel between them. The current inputs and outputs to the bars are positioned thereon intermediate the ends in such a way as to reduce variations in loading between individual cells to a minimum. Several externally commoned inputs and outputs to each bar may be used if required. In the thre-phase arrangement shown in Fig. 3, with 14 diodes between each pair of bus-bars and a single input and output to each bus-bar, the optimum positioning commensurate with the need to dispose the connections between pairs of diodes is as shown. The diodes are clamped to one finned bus-bar and are connected to the other, which is thinner and therefore more resistive, through individual fuses F. Conductor 5 forms a common output conductor for all phases. Where there are a plurality of input conductors for each phase these are preferably strapped together adjacent the bus-bars, especially when the rectifier banks are linearly arranged in phase order RR, YY, BB. Closer balancing of the current distribution may be achieved by inserting impedances in series with individual diodes or by varying the section of the bus-bars as by local reinforcements or sawcuts.
