Title: Non-directional oriented silicon-iron
Inventor: JACKSON JOHN MARTIN
IPC: C21D8/12
Filed: 1959-05-25
Abstract: 877,654. Making magnetic sheets; altering physical properties. ARMCO INTERNATIONAL CORPORATION. May 25,1959, No. 17803/59. Drawings to Specification. Classes 83 (2) and 83 (4) A process of producing high permeability non- directional silicon-iron sheet stock containing from 2.0% to 3.5% silicon, comprises producing a stock in which the crystals are oriented with a (100) plane parallel to the surface of the stock, the cube edges being randomly oriented in the plane of the stock, subjecting said stock to a cold reduction of 55% to 85% and annealing said stock at a temperature of 1400‹ F. to 2200‹ F. in a non-carburizing reducing atmosphere. In an example the initial stock is formed by casting the silicon iron alloy between parallel cooling surfaces having a width and length many times the distance of separation of the surfaces and the cast material is hot rolled before the cold rolling operation. If the initial stock has been cast to size and requires no hot rolling it is annealed before being cold rolled. Where a low carbon content is desired, e.g. 0.007% or less, decarburization may be practised in conjunction with the annealing treatment which may be box annealing or open annealing. The example exhibited . straight grain permeabilities at H M  = 10 oersteds of 1550, cross grain permeabilities of 1520 and intermediate permeabilities in directions lying between the straight grain and the cross-grain.

Title: Elasticized welt for tubular knitted articles
IPC: D04B9/10
Filed: 1972-04-18
Abstract: 1359119 Knitting tubular articles BENTLEY ENG CO Ltd 26 March 1973 [18 April 1972] 17815/72 Headings D1C and D1K When knitting a succession of tubular articles, e.g. hosiery each having elasticized roll welts, the elastic yarn for the welt of one article is incorporated in the preceeding article just before it is pressed off. The elastic yarn is thus temporarily anchored in knitted stitches of the preceeding article, and is retained against whipping back on press-off by a group of non-knitting needles. At an auxiliary station, as Fig. 1, needles are pressing off the stitches of one article. A needle 4 has taken the elastic yarn 3 fed at the main station MS, while the trailing 3a has been knitted by needles 4N. Prior to the 1 x 1 set-out for the next article, a group of needles 7N are raised above normal clearing height. The first needle 9 of the next article assumes a low position, so that the chord of elastic yarn lies inward of the needle circle. When needles 6, 8 are raised they pass in front of the elastic yarn and trap it against the zig-zag formation, of the ground yarn 2. When the yarn is released from the preceeding article whip-back is prevented. The ground yarn is severed by moving the sinkers inwards to press it against the needles 7N and snap it.

Abstract: 178,579. Hay, F. J. Jan. 25, 1921. Indicators, alarm and signal. - Relates to an automatic oil - feed alarm apparatus for motor-vehicles in which a vessel d mounted on a lever h counterweighted at j receives lubricant through a pipe c and has a Leakage hole e which is insufficient to carry off the normal flow of oil, so that if the supply of oil ceases the vessel d empties and the lever h turns about its fulcrum and operates means closing an electric alarm circuit. According to this invention, the electric contact chamber o is arranged outside the main cylinder a containing the vessel d and lever h and the operating pin t passes through a stuffing box r. The pin t, which is provided with a contact-button u, is connected to the lever h by a pin s and is put in circuit with the main cylinder a, which is wired to the frame of the car at z, by a flexible metal wire v. An insulating plate p is arranged on the floor of the chamber o and above it is a contact plate q. A contact w completes the circuit between the plate c and a binding screw x, which is connected to an electric light or bell, and a battery. The Figure shows the device when the circulation is normal, the electric alarm being then inoperative. Oil overflowing from the vessel d leaves the chamber a at f.

Title: Improvements in and relating to electrical control systems and control devices
IPC: G01C19/00
Filed: 1942-01-08
Abstract: 616,603. Automatic control systems for voltage and speed. TUSTIN, A., MORRIS, D. G. O., BRAITHWAITE, R. C., SOMERVILLE, T. B., SIMMONS, J. D., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 8, 1942, Nos. 17931/47 and 17932/47. Divided out of 616,516. [Class 38 (iv)] [Also in Group XXXVII] A controlling quantity, e.g. the potential from a potentiometer 218, governs the make- and-break periods of two vibrators 20, 22 and 21, 23 which determine the energization of a device for producing a controlled quantity, e.g. the current of the metadyne 202, which is also applied to the vibrators to produce an effect opposite to that produced by the controlling quantity. The invention is described with reference to a motor control system in which motor 201 runs under the control of a metadyne 202 operated in accordance with the setting of potentiometer 218. When no current flows through windings 213, 214 of the vibrators, the contacts 20, 22 and 21, 23 make and break to energize variators 201, 207 equally and in opposite directions. When current flows through windings 213, 214, contacts 20, 22 and 21, 23 operate unequally to produce a resultant energization of the variator windings 206, 207 and an output from the metadyne 202 driving the motor 201. The metadyne output is applied to the windings in opposition to the potential from the potentiometer so that for each setting of the potentiometer 218 there is an equilibrium resulting in a corresponding speed of the motor 201. Further windings 219, 220 in series with the motor armature may compensate for the resistance drop in the motor armature and maintain a linear relation between motor speed and the setting of the potentiometer. In modifications, the vibration maintaining coils 211, 212 are each connected in series with their associated contacts across resistances 208, 209, Fig. 3 (not shown); fixed resistances are connected in series with the windings 211, 212, Fig. 4 (not shown); and the windings 211, 212 are connected to tappings on a resistance across the variator windings 206, 207, Fig. 5 (not shown). The controlling and controlled quantities may act mechanically on the vibrators. Two or more controlling quantities may act on the vibrators. Specifications 577,312, 577,315, 579,050, [all in Group XXXVII], and 616,516 are referred to.

Title: Method and apparatus for the manufacture of beams
IPC: B21B1/46
Filed: 1973-04-13
Abstract: 1434215 Making sections; rolling; forging; continuous casting; stretching A ORICHEL 13 April 1973 [15 April 1972] 17946/73 Headings B3A B3M B3E B3F and B3H A method of making beams such as widefianged or H-beams, channel sections or sheet piling, involves initially producing intermediate sections by rough forming an ingot, by continuous casting, or by extrusion; upsetting or stretching the intermediate sections in such a manner that each section, when rolled to its finished size, may produce more than two different final sizes, and passing the sections through rolling stands to produce beams of the required final size. In an example, Fig. 4, an initial ingot 1 is rough rolled at 16 to produce any of the intermediate sections a to f. These sections are then worked by an upsetting and stretching machine 21 is such a way that, after rolling the appropriate workpiece in stands 17 to 19, any of the final sections 1000 to 300 may be produced. The upsetting and stretching machine, Fig. 6, includes upper and lower beams 22, 22a which embrace an intermediate section 38 and are movable towards or away from each other by double-acting rams 23, Fig. 7. The section is held by laterally adjustable clamping jaws and can either be stretched, by urging the beams apart, or upset by moving them together. In the latter case, rams 30 are used to prevent buckling of the web of the section. When the intermediate sections are formed by continuous casting, a mould having the partial section shown in Fig. 10a may be used. The mould has side walls 39b and an adjustable end wall 39c which is movable to vary the size of the corresponding flange of the section. The end wall is coupled to a non-rotatable screw 42a which is axially adjustable by a worm wheel 44.
