IPC: H03G3/22
Filed: 1926-01-25
Abstract: 268,906. Robinson, C., Timmis, A. C., and Beer, C. A. Jan. 25, 1926. Thermionic amplifiers.-The gain or amplification of an amplifier for alternating current of audible or higher frequencies is regulated automatically by wholly electrical means comprising a variable impedance. The Figure shows amplifying valves A and an amplifying and rectifying apparatus B connected across the input. The rectified current is applied across a resistance R and condenser C to produce a voltage determining the impedance of a valve Z. The valve Z may form one arm of a Wheatstone bridge in the circuit to amplifying valve D, as shown, or may be directly a transformer coupled in shunt to or in series with the input to the valve D or to the line. By suitable proportioning the resistance R to the capacity C the control in one sense may be applied quickly and in the opposite sense slowly. A number of valves in parallel biassed to different potentials may be employed to give a more extensive range of volume control.

Title: Improvements in or relating to spirit duplication
IPC: B41M5/04
Filed: 1968-01-16
Abstract: 1,220,226. Printing processes. A. B. DICK CO. 16 Jan., 1968 [16 Jan., 1967], No. 2294/68. Heading B6C. [Also in Division B2] A transparent sheet for use in the preparation of film transparencies imaged by spirit duplication comprises a base sheet in the form of a transparent film having a continuous transparent coating on the surface thereof which coating is not readily soluble in spirit fluids used in spirit duplication but is readily wetted by the fluids used in spirit duplication, is highly receptive to the dye image transferred from the imaged spirit master in spirit duplication and has a relatively high coefficient of friction. A spirit duplication process includes the steps of wetting the transparent sheet with alcohol or aqueous alcohol, pressing the wetted sheet in surface contact with an imaged spirit master and developing the image which has leached from the spirit master to the transparent sheet. The transparent film may be formed of polyester, cellulose acetate, polystyrene or polyvinylidene chloride. The transparent coating may comprise polyvinylidene chloride and a further component selected from colloidal silica, polyvinyl alcohol or partially hydrolysed polyvinyl acetate, e.g. colloidal silica and polyvinylidene chloride present in the ratio of 3 parts by weight colloidal silica to 0À3 to 1À5 parts by weight of polyvinylidene chloride; polyvinyl alcohol and polyvinylidene chloride present in the ratio of 1 part by weight polyvinyl alcohol to 0À5 to 4 parts by weight of polyvinylidene chloride; partially hydrolysed polyvinyl acetate and polyvinylidene chloride present in the ratio of 1 part by weight of partially hydrolysed polyvinyl acetate to 0À5 to 4 parts by weight of polyvinylidene chloride. The transparent coating may also be of polyvinyl alcohol, a methylvinyl ether/maleic anhydride copolymer, polyacrylic acid, methyl cellulose, hydroxypropyl methyl cellulose, a vinylidene chloride/acrylonitrile copolymer or a styrene/butadiene copolymer. The coating may be applied in aqueous solution at a solids content of 2 to 20% by weight and the coating may have a weight of # to 6 pounds per 3000 sq. ft. of surface area. The coating may contain a small amount of wetting agent, e.g. a sulphated ester of oleic acid. The coating may be applied by roller, flow or dip-coating. An air-knife or squeeze rolls may be used to smooth and reduce the coating to the desired coating weight. The coating may be air-dried, e.g. at below 300 F. The coating may be applied to the film while the film is in roll form. The transparent sheet may have a spirit soluble dye image deposited on the surface of the transparent coating; the image may be formed of multiple colours in proper registry.

Title: Process and apparatus for electrical resistance-welding of sheet edges
Inventor: TAPPOLET KARL HEINRICH
IPC: B23K11/00
Filed: 1966-01-18
Abstract: 1,138,470. Welding by pressure. TAGERS G.m.b.H. 18 Jan., 1966, No. 2380/66. Addition to 1,100,851. Heading B3R. In the electrical resistance welding of two edges of a metal sheet or sheets the ends of each of the edges is bent up, the bent up edges are overlapped, forces are applied which tend to bring the bent up edges into close face contact, electrodes are pressed into contact with the overlapping edges in a direction normal to the portions of the sheet or sheets adjacent the bent up edges and current is passed through the sheet or sheets. The ends of a tinned steel strip are bent upwardly and downwardly respectively at right angles to the strip and the strip is formed into a cylindrical can body with the bent ends 3, 4, Fig. 1, abutting on their inner faces and an upper electrode 11 is engaged with the part of the strip adjacent the end 4 to overlap the end 4 and a lower electrode 12 is engaged with the other part of the strip to overlap the end 3. The electrodes extend the length of the edges. An insulated counter pressure member 14 is arranged to abut the outer face of the end 4 and a similar member 13 is arranged to abut the outer face of the end 3. In operation the members 13, 14 press the ends 3, 4 together in directions H, the electrodes 11, 12 are then forced against the strip in directions V, normal to directions 14, and current is passed between the electrodes. The welding apparatus may comprise upper and lower electrodes 11, 12, Fig. 2, carrying strips 13, 14 in recesses 19, 20 with an elastic material 21, 22, e.g. rubber, between the strips and the recesses. The lower electrode 12 is fixed and the upper electrode is movable vertically and horizontally, the latter by an eccentric 24. If the upturned edges are not bent sharply the edges, while pressed together, do not lie in face contact until current is passed to effect their softening. The upturned edges may first be pressed together with a high pressure to produce contact therebetween and the pressure is then reduced before a current impulse is applied. The electrode contact pressure before the current impulse is less than that after the impulse.

Filed: 1924-01-29
Abstract: 236,601. Drysdale, C. V., Smith, B. S., and Mackintosh, E. V. Jan. 29, 1924. Determining distances acoustically.-Heavily damped sounds are emitted at regular intervals of not less than one-tenth of a second by a subaqueous sound-emitter on one side of a ship's hull, and the echoes are detected by a microphone located on the other side of the hull, the telephone receivers being short-circuited except for a brief period which coincides with the arrival of the echo. Thus the current through a sound emitter 6 is suddenly interrupted once per revolution of the shaft 1, the diaphragm of the transmitter being thereupon released to give a damped note. This is effected by means of an insulating segment 4 on the metal disc 9. The telephones 11 are short-circuited by brushes 3 engaging conducting rings 3<a>, 12, except at the instant when the insulating segment 5 is passing under a brush, and this instant can be made to coincide with the arrival of the echo at the microphone 10 by rotating the ring 12. Hence in operating the apparatus the ring 12 is turned until the echoes can be heard in the telephones 11, whereupon the dapth can be read from the uniform scale 23 against the pointer 15. To allow for the inclination of the sound ray, the zero position of the pointer may be varied by a cam. Specifications 22940/14 and 237,933 are referred to.

Title: Manufacture of disazo-dyestuffs
IPC: C09B35/18
Filed: 1942-02-24
Abstract: Disazo dyes are obtained by coupling tetrazotised 3 : 31 - dihydroxy - 4 : 41 - diaminodiphenyl with 2 mols. of the same or different components of which at least one is a 1-hydroxynaphthalenesulphonic acid carrying an auxochromic group, e.g. a substituted or unsubstituted amino group or a hydroxy group, in 8-position.  The products are suitable for dyeing cellulose fibres, e.g. of cotton or regenerated cellulose, or animal fibres, e.g. wool, silk or leather, and may be treated in substance, in the dyebath or on the fibre, with agents yielding metal, e.g. copper, chromium, iron, nickel or cobalt. The metal compounds produced in substance may be incorporated in nitrocellulose lacquers, artificial resins and spinning masses. In examples (1), (2), (4), (6), (7), (8), (10), (11) and (12), tetrazotised 3 : 31-dihydroxy-4 : 41-diaminodiphenyl is coupled with (1) 1 : 8 : 4-aminonaphtholsulphonic acid (2 mols.) in presence of potassium hydroxide, (2) 1 : 8 : 2 : 4-aminonaphtholdisulphonic acid (2 mols.) in presence of potassium hydroxide, (4) 1 : 8 : 4 : 6-aminonaphtholdisulphonic acid (2 mols.) in presence of potassium hydroxide, (6), (7) and (8) 1 : 8 : 3 : 6-aminonaphtholdisulphonic acid (2 mols.) in presence of magnesium hydroxide, barium oxide and calcium hydroxide respectively, (10) 1 : 8 : 4-dihydroxynaphthalene sulphonic acid (2 mols.) in presence of potassium hydroxide, (11) N-toluenesulphonyl - 1 : 8 : 4 - aminonaphtholsulphonic acid (2 mols.) in presence of calcium hydroxide, (12) N-phenyl-1 : 8 : 4-aminonaphtholsulphonic acid (2 mols.) in presence of potassium hydroxide.  Examples (3), (5) and (9) relate to the production in substance of the copper compounds of the dyestuffs of examples (2), (4) and (8) respectively.  In an example of the dyeing process, well-wetted cotton is introduced into an aqueous solution at 50 DEG C. containing the dyestuff of (1) and sodium carbonate, the temperature is raised to 95 DEG  C. with addition of Glauber salt and so maintained for 1 hour, whereupon copper sodium tartrate is added, the temperature is maintained for 1/2 hour at 80-90 DEG  C. and the cotton is rinsed and, if necessary, soaped to obtain a fast blue dyeing.  Specifications 12932/15, 102,881, [both in Class 2 (iii)], 455,274 and 609,299 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of unsulphonated 1-hydroxynaphthalenes containing an auxochromic group in the 8-position.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electric motor control systems
IPC: H02P1/02
Filed: 1944-02-11
Abstract: 577,220. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. Feb. 11, 1944, No. 2562. Convention date, Feb. 11, 1943. [Class 38 (iii)] An electric motor control system comprises means whereby a signalling device is operated by a manual switch, upon subsequent operation of which an electromagnetic starting switch responds to start the motor, the said means being so controlled by the starting switch as to be reset immediately upon response thereof, and to be effective when the motor is re-started through the manual switch. When a pushbutton 12 is depressed a relay 18 is energised to actuate a relay 19 and a signalling bell 23, and when it is released, the relay 18 will be de-energised but the relay 19 remains energised, a relay 20 being energised through a circuit including a normally-closed contact 18c. When the button 12 is depressed a second time a main switch 8 is energised to connect the primary winding of the motor to the supply lines for forward rotation, and at the same time the relay 19 together with the signalling device 23 and relay 20 are de-energised. A relay 17 is energised through contacts 8h, which are under the control of a time-delay device, to short-circuit an adjustable portion of each of the sections 31, 41, 51 of the motor secondary resistance for a pre-determined period to provide a good starting-torque. When the button 12 is released the motor stops and the system is restored to the original condition. To operate the motor continuously the button 11 is depressed and the operation of the relays and signalling device is similar to that previously obtaining except that a relay 15 and the switch 8 remain energised when the button is released. The switch 17 again temporarily short circuits the motor resistances. To accelerate the motor a controller 14 is moved so that the switches 60, 61, 62 close to respectively short circuit corresponding sections of the rotor resistance. When a push-button 13 is depressed the operation of the relays and signalling device is similar to that previously described except that the switch 9 is energised to rotate the motor in the reverse direction, the release of the push button stopping the motor. To stop the motor when running forwardly a switch 10 is depressed momentarily to de-energise switches 15 and 8 and disconnect the motor from the line. A relay 16 is energised through a contact of a relay 21, which was closed when the motor was forwardly started, and upon re-closing of the switch 10, the reverse switch 9 is closed to connect the motor to the line for reverse rotation. Windings 21d and 21c of the relay 21 have opposing effects, and as the motor slows down the pull of the winding 21c overcomes that of 21d and moves the contact-arm of the relay to the open position, thus de-energising the relay 16 and the switch 9, to disconnect the motor from the line. Specifications 376,522 and 532,989 are referred to.
