Title: Copying process
IPC: H05B6/60
Filed: 1971-06-23
Abstract: 1349773 Printing W KORESKA 23 June 1971 [23 June 1970] 29494/71 Heading B6C In a copying process a latent image is formed on a copy sheet by writing or similar pressure and subsequently made visible by a chemical reaction produced by heating, the heating being effected by the action of a dielectric high frequency field, the frequency being such that the polarity of the field is altering several million times a second. In one example given, the under faces of the uppermost and intermediate sheets of a number of superposed sheets have a layer of methyl gallate in a vinyl resin binder and the upper faces of the intermediate sheets and the lowermost sheets have thereon a waxy layer of iron stearate in ozocerite. During writing on the uppermost sheet, the layers coact to form latent images on the copy sheets which are developed by heating the assembly of sheets as set out above. The assembly of sheets, which may be in zig-zag folded form, may be moved through the high frequency field so as to prevent overheating by standing waves. The electrodes may be in the form of rods disposed transversely to and under a conveyer belt of a low loss plastics material, e.g. a polyester.

Title: Improvements relating to electric translation apparatus
IPC: G01D5/30
Filed: 1956-09-28
Abstract: 824,128. Electric translation apparatus. GENERAL ELECTRIC CO. Sept. 28, 1956 [Sept. 30, 1955], No. 29703/56. Class 40 (3). In an apparatus for obtaining an A.C. potential at a frequency determined by a D.C. potential, the resistance of a photo-cell controls the frequency of a relaxation oscillator, the photo-cell being illuminated by light falling thereon in an amount which is varied by means responsive to the difference between the D.C. potential and a feed-back direct potential of magnitude dependent upon the frequency of the oscillator. In Fig. 1, the frequency of a relaxation oscillator 10 is controlled by the relative amounts of light reflected upon a pair of photo-cells 11, 12, by the mirror 18 of a galvanometer 17 from a light source 20. A conventional A.C. amplifier 13 amplifies and differentiates the oscillations of the oscillator 10 to provide a series of relatively sharp pulses which are applied to a bistable multivibrator 14 which provides an output of square-wave oscillations at a frequency of one half that of the oscillator 10. The output of the multivibrator 14 is amplified by an amplifier 15, from which the A.C. output may be taken. The output of the amplifier 15 is fed to an A.C.-D.C. converter 16 having a saturable core transformer which will saturate during each half-cycle of the highest frequency squarewave oscillation that will be impressed upon its primary winding. The output of the transformer, consisting of pulses of constant amplitude and width at a frequency which varies with the frequency impressed upon its primary, are rectified and applied to the galvanometer 17 in opposition to the D.C. input and to a D.C. reference potential which ensures that the apparatus operates at a desired frequency corresponding to zero D.C. input. In use, the light beam is so reflected by the galvanometer mirror that the sum of the D.C. input and D.C. reference voltages equals the D.C. feed-back voltage and frequency of the A.C. output is then determined by the D.C. input. In the detailed circuit arrangement, Fig. 2 (not shown), the A.C. output is derived from the output of the multivibrator 14.

Title: A process and apparatus for intimately contacting two immiscible or only partially miscible liquids
IPC: B01D11/04
Filed: 1947-11-07
Abstract: A process and apparatus for purifying oils in which the oil, for example lubricating oil distillate, and a liquid-extracting medium, for example alcohol, are brought into intimate contact, one liquid being injected into the other drop by drop by causing it to move intermittently through openings in a wall, as described in Specification 414,734, are modified in that the contacting zone comprises at least three compartments and the quantities of the liquids flowing out of the middle compartment are <PICT:0632888/III/1> <PICT:0632888/III/2> <PICT:0632888/III/3> automatically controlled in such a manner that after each cycle the interface between the liquids in this compartment remains entirely or substantially at the same level.  As shown in Fig. 2, imperforate partitions 6 extend across the column 5 and are provided with vertical tubes 15 closed at their ends and with perforations in their side walls.  Oscillation of the liquids with respect to the partition forces light liquid into heavy and vice versa.  Should one liquid become smaller in volume due to the removal of impurities &c. one end of the tube extends into the other liquid so that a quantity of this liquid is returned to the end compartment from which it originated so as to maintain an equilibrium of the interface level.  Fig. 6 shows a modification in which perforated partitions are arranged across the column at an inclination such that a similar action takes place. Vertical perforated partitions may be provided, connected to the side walls by alternate horizontal impervious partitions.  Small points, bars or plates may be placed above and below the perforations to disperse the liquids as they surge to and fro.  In a modification shown in Fig. 9, the column 5 is placed horizontally and perforated partitions 22 extend substantially horizontally at the interface of the liquids between pairs of vertical partitions 20, 21 to permit recycling, if one liquid increases in volume relatively to the other, as the liquids surge under the action of pumps 11, 12.  Fig. 19 shows a modification in which recyling is made unnecessary by periodically changing the volume of certain of the compartments in tune to the oscillating flow of the liquids.  A U-shaped tube 29 is secured to each of the middle compartments, one end in contact with the light liquid and the other in contact with the heavy.  A cylinder 24 is provided for each compartment substantially at the interface level of the liquids.  A piston 25 slides in the cylinder 24 between stops 26, 27 to vary the volume of the compartment, the stop 27 being adjusted by means of a controlling mechanism 28 responsive to the interface level of the liquids in the tube 29.  The expansion cylinder 24 may be replaced by a bellows or a diaphragm.  The level controlling mechanism may be placed inside the compartment.

Abstract: 715,346. Welding by pressure. WUPPERMANN GES., T. Dec. 24, 1951 [Dec. 23, 1950; Dec. 23, 1950; Dec. 23, 1950; Dec. 23, 1950], No. 30136/51. Class 83 (4). In pressure butt-welding metal work-pieces of solid cross-section the surfaces to be welded are preheated by a high-frequency inductor while spaced apart and thereafter an arc is produced between the surfaces without contact between them and they are subsequently moved towards one another for welding while the arc continues. The arc may be struck by a condenser discharge or by ionizing the gap by #-rays. The arc circuit is separate from that of the inductor and may be supplied at 6-10 volts at a frequency below 50 cycles per second, preferably 16<SP>2</SP>/ 3  cycles per second. In an embodiment work-pieces are clamped in spaced blocks 1, 2 and are heated by an inductor positioned between the ends. The inductor is swung out from between the work-pieces and the work-piece in the block 1 is rapidly moved towards the other piece by the straightening of a toggle lever 4 between the block 1 and a slide 3. A pneumatic or hydraulic piston 6 acts on the pivot 5 of the lever 4 which pivot may be moved over the dead-centre position. An arc is struck across the gap between the pieces and the latter are slowly moved together by movement of the slide 3 transmitted through the rigid lever 4. The movement of the piston 6 is preferably dependent on the movement of the inductor.
