Title: Improvements in or relating to an apparatus for producing periodic m.m.f. impulses
IPC: H02M1/26
Filed: 1956-09-28
Abstract: 788,438. Converting. SIEMENS-SCHUCKERTWERKE AKT.-GES. Sept. 28, 1956 [Sept. 30, 1955], No. 29760/56. Addition to 745,173. Class 38 (2). In a contact converter having a switch choke 12 in series with each contact 13, remagnetized before contact closing for phase angle control by a pulse producing circuit including a saturable choke 6 of the kind forming the subject of parent Specification, the premagnetization of choke 6 and therefore the output volts of the converter are influenced by a variable quantity of the converter, such as its output current or voltage. In Fig. 1, which shows a constant current circuit, the load current passes through a winding 26 on each choke 6 in such direction that upon variation of the current, the pulse produced in the circuit comprising rectifier 25 and series windings 7, 4 on chokes 6, 2 respectively, which partially remagnetizes choke 2, is so varied that the length of the contact step after contact closure is altered in that direction which tends to restore the current to its original value. The output voltage or the speed of a motor energized by the converter may be kept constant by passing through winding 26 a current dependent on the quantity to be controlled.

Title: Improvements in continuous process for the manufacture of simple or mixed ethers of the fatty series
IPC: C07C43/06
Filed: 1925-11-25
Abstract: 243,736. Distilleries des Deux-SÞvres. Nov. 26, 1924, [Convention date]. Alcoholic liytids, distilling. - Simple and mixed ethers are prepared by a continuous process which consists in removing the water formed by the reaction of sulphuric or other acid and alcohols by adding a body such as gasolene or benzine, which forms an azeotropic mixture with water and distilling. The reaction mixture is heated in a boiler 1 and the vapours pass to Ó rectifying-column 3 to which a condenser 5 and dehydrating-apparatus 8 are connected. The ether is removed by a condenser 12 connected to the uppelr part of the column. In a modification for preparing higher ethers, the ethers are removed from the bottom of the column. In the case of butyl ether, for example, the products of reaction themselves form an azeotropic mixture with water.

Title: Improvements in or relating to direct reduction processes for producing carbon binding metal or metal alloy
IPC: C21B13/12
Filed: 1925-11-26
Abstract: 243,743. Flodin, H. G., and Gustafsson, E. G. T. Nov. 27, 1924, [Convention date]. Dry processes of extracting metals; alloys.-In a process for producing carbon binding metals and alloys, a mixture of oxide ore and carbon, part of which may be replaced by ferro-silicon, ferromanganese or aluminium, is fed into a slag bath in an electric furnace provided with movable electrodes, and the temperature of the slag bath and the metal &c. is regulated during reduction by varying the height of the electrodes above the bottom of the furnace and thereby heating different layers of the slag bath. The electrodes are raised to such a position that they form arcs between the slag bath and themselves, thus heating the upper portions of the said bath during the reduction of the ores, and at the end of this process to such a position that they just contact with the bath. To attain a sufficiently high temperature in the molten metal just before tapping, the electrodes are lowered so that they are immrsed in the slag bath to such an extent that they almost contact with the molten metal. The charge is fed continuously into the furnace, but is cut off for a suitable length of time before tapping the metal. The metal may be desulphurized and dephosphorized before tapping by removing the whole or part of the slag, adding substances such as lime, carbon, and fluorspar to the bath and then operating with the electrodes in such a position as to form arcs between the electrodes and the slag bath, the slag produced being removed before the metal is tapped. The furnace may also be provided with a conducting bottom or bottom electrodes for concentrating the heat in the bottom of the furnace, i.e. in the metal bath. The mixture of ore and reducing agent may be finely crushed and formed into briquettes &c., with or without the use of binding agents, the briquettes &c. being dried in air &c. before feeding into the furnace.

Title: Elastomeric copolymers of ethylene and process for the production thereof
Inventor: LANE ZIMMERMANN ROBERT
IPC: C08F10/00
Filed: 1959-09-02
Abstract: Essentially linear elastomeric copolymers of ethylene and an aliphatic polyol vinyl ether are made, said ether containing at least one vinyl group.  The copolymer preferably contains a major proportion of ethylene and may contain additional monomers such as vinyl acetate formate or propionate, vinyl ethyl, vinyl-2-chloro-ethyl, vinyl butyl or vinyl cyclohexyl ethers.  The polyol vinyl ether may be a mono-or polyvinyl ether of an aliphatic polyol such as a glycol or a polyglycol, e.g. ethylene or polyethylene glycols, propylene, hexamethylene or octamethylene glycols, 2,2-dimethyl-1,3-propanediol, or a vinyl ether of a triol such as glycerine and mixtures of these vinyl ethers may be used. The copolymer may be made by partially copolymerizing the polyol vinyl ether with ethylene under high pressures and temperatures in the presence of a catalyst, the reaction being interrupted before all the polyol ether has been polymerized.  The catalyst may be lauroyl, dicumyl or di-t-butyl peroxide or t-butyl hydroperoxide and the copolymerization may be carried out in bulk or in a diluent such as an aromatic hydrocarbon or t-butyl alcohol or in aqueous emulsion employing emulsifying agents such as sodium dioctyl sulphosuccinate, and chain modifiers such as mercaptans may be present.  The copolymers produced are noncross-linked and soluble in various solvents and may be employed in graft copolymerization, e.g. with alkenyl aromatic monomers such as styrene, vinyl toluene or chloro-styrenes.  The copolymers may be compounded with various fillers such as carbon black, finely-divided silica, calcium carbonate, calcium silicate or glass fibres and may be moulded or sheeted out to products which can be cured by Friedel-Crafts catalysts, e.g. BF3, X-rays or g -rays, U.V. radiation or simply by heating.

IPC: H03K23/74
Filed: 1951-12-28
Abstract: 709,456. Automatic exchange systems. SIEMENS BROS. & CO., Ltd. Dec. 12, 1952 [Dec. 28, 1951], No. 30350/51. Class 40 (4) A register sender has a control relay controlled by the contacts of the sending and receiving relays arranged so that sending cannot overtake receiving. When the register sender is taken into use earth is connected to contact ds and the first relay NA (not shown) in the sending distributer operates. The circuit to AA is held open by a contact not shown. While the first digit is being registered on apparatus (not shown) contacts ds operate to energize A, which removes the shunt from DR, which then pulls up over na. At the end of the digit ds restores to operate B in series with the right hand winding of A. Contacts b1 operate to restore DR. While the second digit is being entered ds operates to release A and at the end of the digit ds restores to operate C, the process repeating for each relay in the digit-receive chain A-H. When impulse sending is to begin the contact (not shown) in the dotted line to the impulse generator AA closes and with DR released AA sends out impulses as described in Specification 654,849. After the first digit has been sent a stop relay energizes to operate NB (not shown) and then releases to.restore NA. Provided C or a later relay is operated at this time, DR remains released and sending continues. If, however, sending catches up with digit registration corresponding relays in the two chains A-H and NA-NH (not shown) will be operated and DR pulls up to break the circuit to AA to stop sending.

Title: Improvements in or relating to stroboscopes
Inventor: WHITE BARRINGTON JOHN LEONARD
IPC: H05B41/34
Filed: 1961-08-24
Abstract: 984,935. Stroboscopes. DAWE INSTRUMENTS Ltd. Aug. 24,1962 [Aug. 24, 1961], No. 30574/61. Heading G2J. [Also in Division H3] A circuit for energizing a stroboscopic flash tube comprises a trigger circuit which may be synchronized optionally from an internal or external source of oscillations and a differentiating circuit applying the output of the trigger circuit to a pulse amplifier energizing the flash tube and comprising a transistor connected in the commonemitter configuration and a rectifier diode,whose characteristic is such that its impedance falls suddenly when the potential across it reaches a predetermined value in excess of 0.5 volts, connected so as to conduct in its low impedance direction in series in the emitter circuit of the transistor amplifier. Silicon diodes in which the "knee" of the characteristic is at about 0. 6 volt or Zener diodes may be used. In the circuit shown silicon diodes 3, 9 are connected in series in the emitter circuits of NPN and PNP transistors 2, 8. In the absence of an input signal current does not flow in transistors 2, 8, even under conditions of high temperature owing to the high impedance presented by diodes 3, 9, and the circuit remains stable. A positive input pulse of sufficient amplitude causes both transistors 2, 8 to conduct and a current pulse to flow through the primary winding of output transformer 10, which supplies the trigger electrode of a flash tube. Pulses for application to the amplifier circuit are derived by differentiating the rectangular wave output of a bi-stable circuit comprising reciprocally coupled transistors 30, 31, the controlling input for which is derived either from an internal oscillator connected at point 33,an external source connected at point 32, or periodically closed contacts 24. A frequency meter 40 is connected through diode 42 and capacitor 41 to the collector of transistor 31. As the transistor becomes conductive,the capacitor discharges through diode 43 and then re-charges through the meter 40 when the transistor switches off again. Zener diode 44 defines the voltage at the collector electrode when the transistor is non-conducting so as to ensure a uniform amplitude for the pulses applied to meter 40.
