Title: Improvements in methods of and means for bending metal strip to helical form
IPC: H02K15/02
Filed: 1933-10-26
Abstract: 411,746. Coiling strip. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fisher, F. E. ; 36, Sanders Avenue, Scotia, New York, U.S.A.) Oct. 26, 1933, No. 29744. Convention date, Oct. 26, 1932. [Class 83 (iv).] In a machine for forming cores for dynamo-electric machines, a flat slotted strip is wound edgewise between flat surfaces on members pivoted on an axis perpendicular to the strip. The strip is fed into an intermittently operated press which divides it longitudinally into two interlocking strips formed with slots and teeth as described in Specification 411,738. The two strips then pass separately into intermit - tently operated bending units A, B which wind them edgewise into helical form. Coiling. Members 44, 45 with interengaging shoulders are keyed on a shaft 30 and form a channel 46, Fig. 3, with bulged side 106, Fig. 10, into which the stock is fed tangentially. The members 44, 45 are intermittently rotated by a connecting-rod attached to a hub 32 on the shaft 30. On the forward stroke, the members are clamped together to pull a length of strip into the machine by wedge projections 56 on the oscillating member 32 forcing members 44, 45 slightly to the left against a head 42. On the back stroke the wedges move in recesses to release the stock when the members are separated by springs 58. The wedges are actuated by stop screws and cams 68 which give a sharp movement to the wedges to clamp the strip. The member 44 is provided with a diagonal slot 71, Fig. 3, at 240‹ to the point of entrance of the strip, along which the coil is fed to an annular receiving channel 73 formed between the head 42 and the member 44 on the shaft 30. A diagonal opening in the head 42 discharges the coil to a core support 111. Sizing pins 76 advanced by a cam plate 43 are projected at intervals into the slots of the coil to prevent accumulative error in the registration of the slots. A roller clutch exerts tension on the coils in the channel 73 during the idle stroke of the shaft 30 to assist it from the channel 73. In a modification, the coiling and receiving members are actuated independently and a transfer means between the members is provided. Specification 406,951 also is referred to.

Filed: 1958-09-18
Abstract: 874,453. Electromagnetic relays. DASCHKE, A. W., and SNELL, W. G. Sept. 18, 1958, No. 29918/58. Class 38 (5). [Also in Group XXXVI] A frequency responsive relay and indicator has tuned reeds 18 surrounded by a coil 22 and aligned with markings on a scale 14 behind a window 12 in a casing 10. Parallel to the two end reeds 18 are two magnetic movable contact members 25, 26 with bent-over ends 25a, 26a. When one of the end reeds 18 vibrates it engages the respective end 25a or 26a to move the member 25 or 26 to the right so that it is attracted by a permanent magnet contact 32 or 33. The members 25, 26 are reset by energization of respective coils 34, 35 causing plungers 36 to strike the members 25, 26. Members 25, 26 preferably vibrate at a relatively low frequency so as to be unaffected by the operating-coil flux. In Fig. 4 (not shown), a single coil is adapted to reset both contacts by means of a cross-bar on its plunger. In Figs. 5 and 6 (not shown), the contacts are manually reset by rotation of a knob mounted on a spindle carrying a bar which can engage either contact, a torsion spring normally maintaining the parts in a neutral position.

Title: Improvements in methods and means for producing malleable iron and steel directly out of oxide ore
IPC: C21B13/12
Filed: 1926-11-26
Abstract: 262,126. Gustafsson, E. G. T. Nov. 28, 1925, [Convention date]. Extracting.-In a process for producing malleable iron and steel in a closed electric furnace, 'the quantity of reducing agent, consisting wholly or partially of carbonaceous material, added during the first part of the smelting operation is less than that theoretically required for the complete reduction of the ore and during the latter portion of the smelting a further quantity of reducing agent is supplied so that the total quantity of reducing agent is in excess of that theoretically required for the reduction of the ore simultaneously supplied, and the desired carbon content of the product is obtained. The second supply of carbonaceous material is fed into the furnace on to the slag bath for the purpose of reducing the metal oxide in the slag and also carbonizing the metal produced by the first part of the smelting process, which is carried out by the process described in Specification 262,127. When producing iron or steel low in phosphorus from an ore rich in phosphorus, the shortness of the carbon in the charge is arranged so as to produce an iron with a carbon content of about 0.10 per cent, and after the slag has been removed a charge with excess of carbon or a carbonaceous material alone may be added to the iron in the same or another furnace, if desired after a new slag has been formed on the iron.

Title: Improvements in magnetic sound records
IPC: C09D5/23
Filed: 1928-10-17
Abstract: 324,099. McClelland, T. Oct. 17, 1928. Records, magnetic; materials for; sound traces; records, combined phonograph and kinematograph.-Magnetic sound records comprise a track adapted to be magnetized in accordance with the sounds to be recorded and consisting of a substantially continuous belt of discrete particles embedded or enclosed in a matrix carried by or in a suitable carrier base. The base may be in the form of a ribbon or film of celluloid or metal, and the track may consist of steel filings or powder embedded in a matrix of celluloid or coliodion. The sound track may be affixed by pressing the moving base against a roller which is partially immersed in the matrix containing the magnetic particles, the sound track being forced to a certain extent into the base. Another method of attaching the track is to spray the matrix containing steel powder &c. on to the base. In another form, the base may be a ribbon of textile material which is impregnated with the matrix containing the magnetic element. The record may also be formed by blowing magnetic powder into the interior of a tube of textile material, applying celluloid solution, and flattening the tube. If desired, a plurality of parallel tracks may be applied to either or both of the faces of the base, and such tracks may be used either successively for recording lengthy matters on a strip by a lateral displacement at each end of the strip and continuation in the reverse direction on the next track, or so that each track may represent the simultaneous but separate record of different portions of an orchestral &c. rendering. In connection with combined sound and picture films, the magnetizable track and matrix are carried by the film. The Provisional Specification describes also the use of a metallic wire or a solution of iron as the magnetizable element.

Filed: 1928-10-17
Abstract: 321,794. Shimwell, O., and Gawsworth Patents, Ltd. Oct. 17, 1928. Shuttleless looms.-In looms of the type described in Specification 233,099, wherein the weft is drawn out into loop form at each side of the loom, the legs of each loop being successively drawn into the warps by a weft carrier, the length of the loops is varied by adjusting the positions of the yarn cutting and clamping members u, q, r, Fig. 6, for the ends of the loops. For this purpose, the members u, q, r are housed in brackets n, o, Fig. 1, which are adjustably bolted in slots k, m, in a frame a. The yarn clamping and cutting members in the bracket o comprise a stationary clamp and a stationary cutting blade with which co-operate a clamp and a cutter carried by spring-controlled bell-crank levers operated by a lever y, Fig. 6, controlled by a cam z on the shaft e. The lever y is fixed to a spindle 2, connected by lever-members 3, 4, to a barrel 5 carrying a thread guide p whereby, when the shaft e is oscillated, the thread-guide p also is oscillated. The yarn clamping and cutting members in the bracket n are actuated by separate cams on the shaft e. The weft which is attached to one of the clippers and extends to the bobbins through a tensioning device comprising the guide eyes 23, 24 and an adjustable intermediate friction pad 25 is engaged by the double hooks 26 on an endless chain 15 passing over sprocket wheels j, 16, 17, 18 and an adjustable tensioning sprocket wheel 19, whereby it is drawn into loop form as shown in Figs. 7 and 8. The upper clip and blade are now closed, and one leg of the loop is cut and transferred to the shed by the weft carrier 28, Fig. 1. Theneafter, the lower clip is opened and the other leg of the loop is inserted into the cloth. The end of the thread is now held in the upper clip and on the guide eye p being turned on the shaft e, the yarn is again placed in the path of the hooks 26 and a fresh loop is formed. As the hooks 26 reach the sprocket wheel 18, which is the limit of their traverse with the weft threads thereon, a guide 14, operated by gearing 13, 12, 11, 10, 9 from a cam on the shaft e, is lowered into the loop to receive the thread as it is released by the turning of the chain 15 on the sprocket. A depressing lever 29 lowers the legs of the loop into the path of the carrier 28.

Interference due to multi-hop paths is thereby avoided. In the embodiment the law is sawtooth. Sawtooth voltage generator, Fig. 2.-Clock pulses are fed to the negative input of an operational amplifier 28 acting as an integrator having a long time-constant; an F.E.T. 36 across a capacitor 29 is in the feedback path. The output of the operational amplifier is connected as shown to the positive input of a second operational amplifier 31 which acts as an adder with an adjustable D.C. via potentiometer 34 for adjusting the band of the frequency variation in a voltage-to-frequency converter, see below. Voltage-to-frequency conversion is effected in an arrangement consisting of a relaxation circuit followed by an amplifier and a flip-flop Fig. 5 (not shown), the output being square wave signals of linearly varying frequency. Receiver, Fig. 6.-A filter 44 is connected to a mixer 46 and to a circuit 54 for synchronizing variable-frequency local oscillator 47. The pathselection band-pass filter 48 is followed by a further mixer 49, associated with a fixed-frequency local oscillator 50 and feeding into a square-law detector 51 to which is connected a threshold circuit 52 from which information signals are fed to utilization means. Other paths may be parallel, each path having its own oscillators, mixers &c. and being synchronized from separate outputs from circuit 54. (Each path has its own frequency-modulated transmitter oscillator).
