Title: An improved control for the adjustment of the rolls of rolling mills
IPC: B21B37/60
Filed: 1932-10-29
Abstract: 395,916. Control of motors. KRUPP GRUSONWERK AKT.-'GES., F., Buckau, Magdeburg, Germany. Oct. 29, 1932, No. 30414. Convention date, Nov. 6, 1931. [Class 38 (iii).] Travelling to predetermined limits.-The electric motor for adjusting the pass of a rolling-mill is adapted to be cut out when the adjustable roll has reached a predetermined position, the mechanism comprising a disc driven by the setting gear and having adjustable means about its circumference for operating a contact device. A disc 2, Fig: 1, performs one revolution for a maximum adjustment of the pass, and carries a number of spring retained bolts which are normally carried at the inner ends of radial slots 3, but may be moved to the outer ends of the slots, bolts in the latter position being adapted to actuate the switching- out device for the motor, and therefore being selected at positions corresponding to the sizes of the successive passes required. An arm 8 is pressed resiliently towards the disc 2 and carries an arm 15 on. which is a roller 14 which is engaged by bolts in the outer position to rock the arm 8 and actuate the press-button 12 of the switch 13 controlling the motor. The arm 15 is so mounted that it yields without moving the arm 8 when the rolls are opened. Press-buttons are provided for starting the motor in the inward or outward direction and for stopping the motor, a limit switch for the outward movement preventing excess movement. The press-button D, Fig. 4, for controlling the cut-out. S for the inward movement of the rolls is in circuit with an auxiliary cut-out R which allows the switch E controlled by the disc 2 to switch off the motor even if the switch D remains depressed. Actuation of press-button D closes contacts k<1>, k<2> to excite the cut-out S and to switch in the motor. Contacts k<3>, k<4> are closed by the cut-out S to excite the cut-out R, and contacts k<7>, k<8> also having been closed, this causes the contact k<9>, k<10> to be broken so that the cut-out S is supplied only through contacts k<13>, k<14>, line b, and contacts, k<5>, k<6> while the circuit to, cut-out R is now completed through contacts k<11>, k<12>. When the switch E is actuated by the disc 2, the motor is therefore switched out, and cannot be switched in again until the press button D is released, thereby closing contacts k<9>, k<10> and again depressed.

Title: Method and apparatus for the working of material by means of a beam of charge carriers
IPC: B23K15/08
Filed: 1960-09-05
Abstract: 919,299. Electron beam apparatus. ZEISSSTIFTUNG, CARL, [trading as ZEISS, C]. [Firm of], Sept. 5, 1960 [Sept. 4, 1959; June 1, 1960], No. 30514/60. Class 39 (1). [Also in Groups XXII and XL (b)] Operations on a material, specifically the removal of material by heating and evaporation, soldering or welding, are effected by means of a beam of electric charge carriers, the working cross-section of which is smaller than the area of the place of the material to be worked, which is scanned over the material in synchronism with the scanning of a picture by a television type of scanner, the beam being controlled as to its intensity, position of impact during the scan and velocity of scan in accordance with the content of the picture. The Figure illustrates one embodiment in which an electron beam 5 produced by an evacuated electric discharge apparatus 1 of generally known construction is arranged to impinge a workpiece 11 located within the vacuum chamber and is scanned over the surface of the workpiece in a television type of raster by signals applied to an electromagnetic deflection system 10. 9 comprises an electromagnetic lens, 6 an adjustable beam-shaping aperture, 4 the anode and 3 a modulating electrode by which the intensity of the electron beam, which originates from a cathode 2 may be controlled. Electrode 3 is connected to receive signals through an isolating transformer 21. The beam 5 is modulated so to impinge the material only in response to picture signals of a predetermined magnitude. If this method of working is employed the discharge apparatus 1 may be simplified, Fig. 2 (not shown), by dispensing with the isolation transformer 21 and connection to electrode 3, and the use instead of on/off beam modulation achieved by the use of auxiliary deflection electrodes, to which the picture signal is applied, which determine whether or not the beam is interrupted by an apertured diaphragm.

Abstract: 825,119. Finishing and heating yarns. HEBERLEIN & CO. A. G. Oct. 2, 1957 [Jan. 16, 1957], No. 30884/57. Classes 120(2) and 120(3) Yarns of synthetic organic textile fibres e.g. polyamide or polyester fibres, which have been rendered crimpable by highly twisting, heat-setting and backtwisting, are modified to reduce potential stretch (and thereby increase bulkiness) by subjection under constant tension in fully stretched condition to a moist or dry heat treatment e.g. by means of a gaseous medium such as dry air or steam or by contact with a hot surface, the intensity and duration of which e.g. 70‹-250‹C. for sixty minutes to 0.3 seconds,. is adjusted according to the reduction required. The backtwisted yarn may be (cross) wound under tension on a rigid or partially compressible tube or bobbin of large diameter and heat-treated in this form, or it may be passed continuously, as by transfer between two bobbins, in stretched condition through or in contact with a heating device e.g. an electrically heated metal tube or surface. The heat treatment may be combined with one or more other operations in the production of the crimped yarn for which purpose the heating device may be incorporated in a ring-twisting, up-twisting, false-twisting, spooling or doubling-winder machine e.g. the heater may be fitted on a false-twisting apparatus so that the heat treatment is applied during backtwisting. Single yarns and plies thereof e.g. two single yarns rendered crimpable by high-twisting in opposite directions, may be treated in twisted or doubled form.

Abstract: 236,155. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. June 25, 1924, [Convention date]. Vacuum tubes; vacuum apparatus with reflecting surfaces; low-pressure metallic-vapour apparatus.-Electric discharge tubes in which a light - radiating positive column appears and which comprise two electrodes within a sealed envelope filled with a rare gas in contact with the electrodes are operated at 500 volts or above and are provided with one or more conductive members extending over a considerable length of the tube and along or in the wall thereof out of contact with the gas. Each conductive member may comprise a conductive layer 6, Fig. 1, such as aluminium paste or a silver mirror reflecting light in a predetermined direction, or a copper or other metal wire or band 20, Fig. 3, arranged helically around the tube, disposed within the walls of the tube or enclosed in an insulating tube within the discharge tube. An auxiliarycapacitive discharge between the conductive members or between one member and an electrode lowers the initiating and operating high voltage of the main discharge and permits a reduction in the resistance in series with the tube. At least one conductive member may be connected with one electrode of the tube and two members, such as two helices with their ends near together at the centre of the tube, may be connected to the two electrodes. One member connected to the electrode may be connected to earth, as in Fig. 3, so that nearly the whole tube is at earth potential, the member extending close to the other electrode. Alternatively, the auxiliary discharge may be produced by a voltage separate from the main discharge voltage and preferably of such phase that the auxiliary voltage is a maximum when the main discharge can be initiated. Two conductive layers 6, 7, Fig. 1, on opposite sides of the outer surface of the tube may be supplied with voltage from a transformer 13 separate from the transformer 10 supplying the main discharge, between the electrodes 4, 5 in widened parts 2, 3 of the tube. To prevent discharges along the outer wall of the tube when two conductive members are used, one at least is arranged inside the tube. Several tubes may be connected in parallel across a single transformer. Specification 154,199 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the mixture of a small quantity of mercury or like vapour with the gas.
