Title: Cathode Ray Tube Beam Wobble Circuit for Photo-Type Composition
Inventor: SCHIRA JOHN CHARLES
IPC: B41B19/01
Filed: 1967-06-12
Abstract: 1,181,981. Cathode-ray tube displays. R.C.A. CORPORATION. 13 May, 1968 [12 June, 1967], No. 27093/67. Heading H4T. In an arrangement for tracing Alpha-Numeric characters on the screen of a cathode-ray display tube the characters are formed by a plurality of scan line segments (see Fig. 2) the lengths and spacings of which may be altered to change the "point" size of the character and means are provided for imposing a "spot-wobble" at rightangles to the direction of line scan, the amplitude of the "wobble" being varied directly as the "point" size so that characters of uniform density are produced (see Fig. 3). Fig. 1 shows the general arrangement in which a data processor 40 triggers the vertical sawtooth sweep generator 34, controls the horizontal stepping of the beam via a switch 43, digital counter 42 and D/A converter 44 and controls the beam blanking in accordance with the particular character to be produced. For controlling the "point" size of the characters a potentiometer 36 adjusts the amplitude of the vertical sweep between limits P 1  . . . P N  and for controlling the horizontal spacing of the lines the count in counter 42 is adjusted between the limits P 1  . . . P N  by a switch 43 in response to an output from the data processor. Switch 43 also provides a D.C. bias voltage proportional to the horizontal spacing and this is utilized in a modulator 54 to control the amplitude of a sinusoidal wave output from an oscillator 52 which is supplied to an auxiliary deflection coil 59 to produce the "spotwobble". The invention finds application in an electronic photo-composition system in which the characters are recorded on a photographic film 26 the movement of which is controlled by the data-processor.

Title: Spray apparatus employing a so-called two-fluid nozzle
IPC: B05B12/08
Filed: 1962-07-16
Abstract: 993,277. Spray producers. ONODA CEMENT CO. Ltd. July 16, 1962 [Aug. 23, 1961], No. 27170/62. Heading B2F. Relates to nozzles producing mixtures of two fluids, e.g. liquid and gas, and comprises spraying apparatus employing a plurality of twofluid nozzles coupled to common air piping and common liquid piping wherein there is inserted, in each branch of liquid piping leading from the common liquid piping to a corresponding nozzle, a fluid resistor having a higher fluid resistance than the total fluid resistance of the common and branch liquid piping. As shown in Fig. 2, air is supplied through piping 1 and liquid is supplied through piping 4 to nozzles, 7. Unless the flow of liquid to each nozzle is regulated the liquid content in the sprays will vary, some having too much and others having too little. Means are therefore provided whereby the liquid flow to each individual nozzle may be restricted as required. Air enters a nozzle 7 from piping 1, Fig. 1, and liquid enters from piping 4. The flow of liquid is restricted by an orifice 19 in a member 9, this being held between the end of a branch pipe 11, packing 12 being interposed, and a shoulder 10 so as to be exchangeable with other orifice members. The mixture of air and liquid emerges from a head 14 as a spray. In this embodiment the end space 18 in the nozzle head is hemispherical, Fig. 3.-2. If some of the spray blows back it may leave objectionable liquid deposit on the outside of the nozzle and adjacent piping and, to obviate this, extension pieces elongate the nozzle 7, as shown in Figs. 8 and 9. The restricting orifices, instead of being in interchangeable members, may be permanent, formed in the wall of the nozzle. In another modification the restriction members may be in the course of the liquid piping system.

Abstract: 782,363. Coating with nickel. GENERAL AMERICAN TRANSPORTATION CORPORATION. Sept. 21, 1954 [Jan. 12, 1954], No. 27271/54. Class 82(2) A continuous process of chemically plating with nickel a solid body of catalytic material comprises providing an aqueous nickel cation-hypophosphite anion type bath having a given initial composition and a given initial pH, contacting the body with the bath in order to effect the reduction of nickel cations to metallic nickel and the deposition thereof on the surface of the body along with the oxidation of hypophosphite anions to phosphite anions and resulting in the depletion of both nickel cations and hypophosphite anions in the bath and a decrease in the pH thereof, and adding to the bath (a) a measured amount of alkalizing reagent sufficient to restore the given initial pH thereof, (b) a measured amount of nickel cations related in a first fixed proportion to the added measured amount of alkalizing reagent, and (c) a measured amount of hypophosphite anions related in a second fixed proportion to the added measured amount of nickel cations, said measured additions of nickel cations and hypophosphite anions restoring the given initial compostion of the bath. The initial composition of the bath is preferably based on a ratio between nickel cations and hypiphosphite anions in the range 0.25-1.60, and a concentration of hypophosphite anions in the range 0.15/1.20 moles/litre; and the initial pH is preferably 4.5-6.5. When the initial pH is 4.5-6.5, the first fixed proportion expressed as a ratio between added nickel cations and added hydroxyl anions is in the range 0.50-0.417, and the second fixed proportion expressed as a ratio between added hypophosphite anions and added nickel cations is 3. The bath is preferably of the type containing a complexing agent and an exalting additive, e.g. of the malic acidlactic acidsuccinate, malic acid-succinate, or malic acid-glycine types. The figure shows a continuous system in which plating solution is circulated from storage compartment 19 by pump 18 into condenser 13, thence into the plating tank 12 and ultimately back into regeneration compartment 20 via the vacuum flash evaporators 14 and 15. The plating solution is regenerated by additions, periodic or continuous, of hydroxyl anions, nickel cations and hypophosphite anions to regeneration compartment 20, from stock solutions 26, 27, 28 respectively, which may, be solutions of sodium hydroxide, and, assuming that the bath was initially made up from nickel chloride and sodium hypophosphite, nickel chloride and sodium hypophosphite. This regeneration may be carried out by following the pH controller 23 and using the addition of alkalizing reagent as a reference for establishing the additions of nickel and hypophosphite ions.

Abstract: 581,921. Radiolocation. HARDWICK, J. Oct. 10, 1939, No. 27565. [Class 40 (v)] Relates to systems for locating the position of a distant transmitter, or reflecting body, by using two or more receivers separated by a multiple of the working wave-length, as described in Specification 581,920, and consists in a method of equalizing the gain of each of the receivers which is controlled by an automatic volume control voltage which is independent either of the direct or reflected signal. The control voltage may be introduced directly into each of the receivers at predetermined intervals, not covering a complete period of reception of the position-indicating signal. An auxiliary control signal of variable amplitude is separately radiated, the receivers being made sensitive to this auxiliary signal for a part or all of its duration, but not being a complete period of the position-indicating signal. Fig. 1 shows an installation in which a pulse " signal A, Fig. 2, is fed from a generator 16 to the main transmitting aerial 2, and is picked up, after reflection, say from an invisible aeroplane, by three spaced aerials 3, 4, 5 connected to separate receivers 6, 7, 8. A preliminary pulse B, Fig. 2, is fed from the generator 16 to the auxiliary aerial 10, and is also fed direct to the A.V.C. circuits 13, 12, 14 of the respective receivers through a delay network 15. To prevent the receivers from being paralysed by the main outgoing pulse from the aerial 2, a " suppression " pulse C, having the shape and timing (relatively to the pulses A and B) shown in Fig. 2, is also applied from the generator 16 directly through the lead C to the three receivers 6, 7, 8.
