Title: Improvements in or relating to apparatus for identifying and handling coded information
Inventor: DELL HUGH ALEXANDER
IPC: G06V10/10
Filed: 1954-01-28
Abstract: 806,741. Photo-electric scanning devices. MULLARD RADIO VALVE CO. Ltd. April 28, 1955 [Jan. 28, 1954], No. 2625/56. Class 40 (3). In a system for recognizing printed characters, signals produced by an " arrested spot " scanning system, as described in Specifications 747,718 and 786,885, [Group VI], are compared with signals each corresponding with one of the range of characters to be read. The " arrested spot " scanning system comprises a cathode-ray tube 2 examining, by means of a travelling spot, a sheet 1, reflected light being received on photocells 3. The beam of the tube performs rectilinear scanning movements under the control of time base circuit 4 until a character is encountered. The scan is then arrested and subsidiary time bases in unit 5 scan the character intercepted. The signals produced by the photo-cells during this exploration are compared with standardized signals produced by devices 0, 1, 2, 3, either by scanning typical characters or by using signals previously recorded on a storage device, for example, a magnetic tape. The two sets of signals are fed to gate circuits G, G1, G2, &c. so that a signal is emitted from the gates only when the two signals are identical.

Abstract: 628,842. Electrodeposition of zinc. LOWE, S. P., LONG, G. W., KENT, G. H., DOWNES, K. W., and HUDSON BAY MINING & SMELTING CO., Ltd. Jan. 28, 1947, No. 2668. [Class 41] A method of electrolytically obtaining zinc of high purity from a zinc sulphate electrolyte containing at least one of the impurities lead, copper, cadmium and iron, comprises adjusting the pH value of the electrolyte to a state of equilibrium neutrality, adding cresylic acid and pine oil to the electrolyte in amounts sufficient to reduce the amount of such impurities and not more than will dissolve in the electrolyte, and passing electric current from an impure zinc anode to a cathode through the electrolyte. The electrolyte is maintained substantially quiescent during electrolysis. The amount of cresylic acid added is between 2 and 10 pounds per ton of zinc , deposited and the amount of pine oil is up to 6.5 pounds per ton of zinc deposited. The current density does not substantially exceed 25 amperes per square foot of cathode.

In a space heater comprising a shell 1 mounted on legs 2 and having louvres 4, a removable lid 6 and an air-gas ring burner 5 arranged inside the lower end of the shell, the burner is ignited by a pilot light, the ignition of the pilot light actuating a thermo-couple to open the supply of gas to the burner through a flame failure valve 7. As shown, the burner is supplied with air-gas mixture from pipe 10 through a flame failure valve 7 passing horizontally for ignition through a metal mesh 8. The burner is ignited by a pilot light from a tube 11 containing a filament 11b which when heated by the passage of gas ignites the pilot light. The ignition of the pilot light actuates a thermal-couple which opens valve 7 which remains open until the pilot light is extinguished. A sleeve 12 is provided to protect the filament 11b. In use the products of combustion rise and escape through louvres 4. the first Provisional Specification refers to a tapered flame spreader situated above the burner. Specifications 873,721 and 943,099 also are referred to.

Abstract: 1339693 Vibrators CARL SCHENK MASCHINENFABRIK GmbH 21 Jan 1972 [3 May 1971] 3104/72 Heading F2X [Also in Divisions B1-B2 and B8] A two-mass vibrator system operable at supracritical frequency has a counter-vibratory mass 5 resiliently supported by springs 7, 8 from foundations 9, 10 and a vibratory useful mass resiliently supported by springs 3, 4 from the counter-vibratory mass 5, the mass 5 and the foundations 9, 10 being additionally coupled by vibration-damping elements 11,12 and 13, 14 which serve to prevent high amplitudes of the useful mass developing as the system runs into resonance during shut down. In the embodiment illustrated, the useful mass is a vibratory screen consisting of a screen box 1 and a screen plate 2, and is driven by a vibrator 6 comprising two counter-rotary out-of-balance weights. Other applications include vibratory conveyers or feeders. The vibration-damping elements may alternatively be arranged in pairs at that end of the mass 5 at which the vibrator 6 is situated, and singly at the opposite end (Figs. 2 and 3, not shown). These elements are conveniently at an angle to the foundation plane other than 90 degrees so as to attenuate resonant vibrations in both the vertical and horizontal directions.

In the construction shown, a batch of cigarettes 1, Fig. 1, is pressed with a wrapper into one of a series of movable supports 3, as described in Specification 352,659, leaving the ends 2 of the wrapper projecting upwards. Vertical plates 28, Fig. 4, having base plates 29, are moved inwards towards one another and then downwards on to the cigarettes. Presser members 67, Fig. 1, are then moved towards the plates 28 and cause the upstanding ends 2 of the wrapper to fold over the top of the cigarettes into the angles between the plates 28, 29. The plates 28 are then withdrawn, and the ends of the wrapper are pressed by the members 67 to form a longitudinal seam. If the wrapper is composed of or treated with heat-sealable material, the pressers are provided with electric heaters 71. The pressers 67 are then withdrawn, and the movement of the support 3 carries the package beneath a presser 67, the upstanding seams being folded down on to the package, as shown in Fig. 5. The ends of the wrapper are folded by any suitable mechanism.

Title: Process for the manufacture of aqueous dispersions of rubber
IPC: C08J3/03
Filed: 1932-02-03
Abstract: Aqueous dispersions of rubber are prepared, with a small expenditure of power and without the preliminary step of forming of water-in-rubber dispersion, by masticating plasticized rubber with an aqueous paste of an organic colloid such as soap and an attrition agent, preferably a non-colloidal mineral powder employed as a rubber compounding ingredient such as whiting, slate dust, diatomaceous earth or the substance sold under the Registered Trade Mark "Silex." The dispersions may be diluted with water, which may contain compounding or vulcanizing ingredients in suspension, and may be employed for making rugs by causing fibres to adhere to a fabric foundation, proofing textiles, making compound fabrics or as sealing compositions. Example: 850 parts of reclaim rubber are plasticized in a mixing apparatus with 45 parts of a softener such as cumar, mineral rubber or gum rosin, and are added in mass or progressively to a masticating machine containing a thick paste comprising 160 parts of rosin soap, 700 parts of whiting and 350 parts of water; mastication is continued for 30 to 80 minutes at about 180 DEG  F., water being added if required to maintain the consistency of the mass; the dispersion is diluted with 4000 parts of water to half of which 120 parts of gum tragacanth, 30 parts of sulphur, 50 parts of zinc oxide and 2 parts of a vulcanization ultra-accelerator may be added; alternatively these ingredients may be added in dry form to the diluted dispersion; small quantities of essential oils and preservatives such as ammonia and formaldehyde may be included in the composition.  Specification 351,427 is referred to.ALSO:A rubber composition in the form of an aqueous dispersion which may be employed for proofing textiles, as an adhesive making compound fabrics or rugs, or as a sealing composition, comprises the following ingredients: reclaim rubber 43,4 per cent, softener such as cumar, mineral rubber, or gum rosin 2,3 per cent, rosin soap 8,19 per cent, whiting 35,8 per cent, zinc oxide 2,55 per cent, sulphur 1.53 per cent, water soluble gum such as gum tragacanth 6,13 per cent, vulcanization accelerator 0,10 per cent.
