Title: Improvements in or relating to a method of producing multicolour photographic images, more particularly coloured films
IPC: G03C7/22
Filed: 1932-02-15
Abstract: 397,170. Colour photography. GASPAR, B., 38, Innsbruckerstrasse, Sch÷neberg, Berlin. Feb. 15, 1932, No. 4448. Convention date, Feb. 19, 1931. [Class 98 (ii).] Multicolour photographic images, more particularly kinematograph images, are obtained by the simultaneous copying of a plurality of component colour images on to a light-sensitive multilayer material composed of superposed halogen silver layers. The component images may be united to form a master image or they may be combined by projection. Thus, threepart negatives produced in the usual manner are projected on to the multilayer material with the aid of corresponding filters. Alternatively, a two-colour exposure may be made, with the aid of prisms or half-silvered mirrors, to produce two part negatives on double-width stock or on two separate films, the negative part images being united and copied by contact, or superimposed by projection. Suitable corrective filters are employed. The multilayer emulsions may contain dyes or dyeforming substances. Specification 379,679 is referred to. The Specification as open to inspection under Sect. 91 states also that the component colour images may be copied consecutively. This subject-matter does not appear in the Specification as accepted.

IPC: B64D5/00
Filed: 1945-02-22
Abstract: 604,758. Indicators for towed aircraft. JACK & HEINTZ, Inc. Feb. 22, 1945, No. 4497. Convention date, Jan. 26, 1944. [Class 4] Means for indicating the position of a towed aircraft relative to the towing aircraft comprise an arm universally mounted in the nose of the glider and connected to the tow rope, and an indicator in the form of a miniature aeroplane which is moved over an instrument face provided with graticules in response to movements of the arm so as to indicate the position of the glider to left or right and above or below the towing aircraft. The arm, Figs. 1 and 11, comprises a fork 14 pivoted to a loop 13, through which the tow rope is passed, and carried in a sleeve 15 secured to an extension 17 of a rotatably-mounted ball 16. The latter also has an extension 18 formed with spaced balls 19, 20 engaging blocks 21, 22 mounted for lateral and upward and downward sliding movement respectively in a casting 12. The block 21 carries an arm 23 connected by a cable 31 to a drum 34 on the indicating instrument, and the block 22 an arm 25 connected by a cable 27 to a drum 30. The cables 27, 31, Figs. 8 and 10, are passed twice round the drums and anchored to springs 60. The drum 30 is mounted on a shaft 35 secured to which is a ball 40 engaging a block 41 slidable upwardly and downwardly in a casting 36. The block 41 engages a ball 42 carried at one end of a lever 43, the other end of which carries the miniature aeroplane 9. The lever 43 is pivoted on a pin 44 carried in a block 45 which is pivoted to a casting 48 by means of pins 46, 47 perpendicular to the pin 44. The casting 48 is slidable in the casting 36, and its position is adjustable by rotation of a pin 49. The drum 34 is mounted on a shaft 51 secured to which is a ball 54 engaging a block 55 integral with or secured to the block 45.

Title: Apparatus for tensioning strip materials
Inventor: SPOONER WILLIAM WYCLIFFE
IPC: D06C3/04
Filed: 1957-02-09
Abstract: 833,525. Feeding webs. SPOONER DRYER ENGINEERING CO. Ltd. Nov. 12, 1957 [Feb. 9, 1957], No. 4498/57. Class 100(1) [Also in Group XXXIV] An apparatus for tensioning webs comprises a roller frictionally engaging a length of web, a shaft carrying the roller, one end of the roller being freely rotatable relatively to the shaft, a driving connection between the other end of the roller and the shaft, either the driving connection or the shaft being resilient, whereby the transmission of torque between the roller and the shaft adjacent the one end of the roller @ses a relative angular displacement between the one end of the roller and the adjacent shaft portion, and means for applying braking torque to the shaft to cause the angular displacement. As shown, a braked tensioning roller 19, Fig. 6, is supported at each end by end members 33, 36a freely rotatable on a shaft 30. The end member 36a is connected to one end 37 of a spring 38 attached to a collar 39 keyed to the shaft 30. A disc 34a carrying a pair of electrical contacts 40, 41, Fig. 7, is keyed to the shaft 30. Solenoids 46, 47 operating normally closed, valves 52, 51 respectively are connected through slip rings 45, 44 to the contacts 41, 40, respectively. Variations in tension exerted on web material, not shown, passing around the roller 19 causes relative rotation of the roller 19 and shaft 30, thereby causing a contact 42 on the roller to engage either contact 40 or thereby energizing solenoid 46 or 47. Energization of solenoid 46, as a result of an increase in web tension, causes valve 52 to open, thereby releasing air from a cylinder 50 having a piston which actuates a bell-crank lever 49 attached to a brake strap 28 engaging a brake drum 27 to decrease the braking action. Similarly, energization of the valve 51, as a result of a decrease in tension, causes valve 51 to open to admit air to the cylinder 50, thereby increasing the braking action applied by the strap 28. The cylinder 50 may be permanently connected to a reservoir vessel 53 so that large quantities of air have to be admitted or discharged from the cylinder 50 to effect a given movement of piston in cylinder 50. If the braking torque applied to the shaft 30 is high and the speed of the web 13, Fig. 3, passing around the roller 19 is low, the brake drum is connected to the shaft 30 by step up gearing 68 so that the drum 27 rotates faster than the shaft 30, thereby reducing brake snatch. The web 13 may be initially tensioned by reversely rotating the shaft 30 through worm and wheel gearing 70, a oneway clutch 69 being interposed be tween the brake drum 27 and its carrying shaft to permit this rotation. In a modification, Figs. 4 and 5 (not shown) intended for use when high web tensions apply, the spring 38 may be dispensed with; in this case torsional displacement of the shaft is magnified by a system of levers and gearing which is connected between the roller and disc on the roller shaft. The disc may be graduated for cooperation with a pointer fixed to the roller.

Title: Process for manufacture of titanium dioxide
IPC: C01G23/07
Filed: 1960-02-10
Abstract: <PICT:0913016/III/1> Pigmentary titanium dioxide is prepared by burning titanium tetrachloride with oxygen as an upwardly directed jet stream through a reaction zone containing incandescent coarse titanium dioxide particles, whereby the titanium dioxide is formed out of contact with fixed surfaces.  As shown in the Figure, a vertical cylindrical refractory reaction vessel is provided with an inlet 7 for coarse titanium dioxide particles and an outlet 6 which serves to remove the pigmentary products together with over-flowing coarse tianium dioxide particles.  The gaseous reactants are admitted through a tube 4, normally in admixture or the reactants may be admitted through concentric or juxtaposed orifices such that, as they react, they form one jet stream.  Thus a mixture of p  titanium tetrachloride and oxygen may be fed from a pipe 16 together with a controlled amount of oxygen and/or nitrogen from a vessel 16a.  Some of the titanium dioxide replacement particles may be fed into a conduit 19 in admixture with the gaseous feed which may also contain inert gases, carbon dioxide, carbon monoxide, water vapour, hydrogen, hydrocarbons, ethers or esters as nucleating agents or as suppliers of supplementary heat; aluminium chloride may be added as a rutile promoter.  The titanium dioxide particles are generally between 10 and 65 mesh, coarser particles being removed and submitted to chlorination. According to Examples (1) a reactor was preheated to 800 DEG C. and coarse titanium dioxide was fed in and the reactor thereafter heated by the admission of carbon monoxide through an inlet 5 together with a nitrogen/oxygen mixture from pipe 4.  When the temperature reached 1200 DEG C. a mixture of titanium tetrachloride and oxygen in a 1-1,1 mol. ratio and containing 2% of aluminium chloride was fed in through pipe 4 at 300 DEG C.  The carbon monoxide-oxygen feed was adjusted to maintain the bed temperature at 1200 DEG C.; titanium dioxide solids were fed in from the top at 250 DEG C.  No titanium dioxide incrustations occurred. (3) Titanium dioxide was fed as atomized liquid spray through a pipe passing through cap 21 and terminating at a nozzle at 4a at 90 DEG C., whilst oxygen was fed from line 16 at 300 DEG C.  Reference has been directed by the Comptroller to Specification 801,315.

Filed: 1975-02-04
Abstract: 1451183 Induction heating cooking apparatus MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 4 Feb 1975 [5 Feb 1974] 4704/75 Headings H2H and H2F An induction heating cooking apparatus comprises an inverter fed from an A.C. source by way of a full wave rectifier, the induction heating element be energized by the output from the inverter which inverter comprises a thyristor and a diode in back-to-back connection, the apparatus being provided with means for inhibiting the energization of the heating element in the absence of a cooking pan from the element. Induction heating cooking apparatus comprises a heating element 22 which cooperates with a cooking pan 23, the heating element 22 being energized by an inverter comprising a back-to-back connected thyristor 20 and diode 21 at a high frequency determined by the resonance of the heating element 22 with a capacitor 18, the supply to the inverter being from an A.C. source 12 by way of the unsmoothed output of a full wave rectifier 13. Firing pulses for the thyristor 20 are supplied by a pulse generator 26 by way of a thyristor 24 and a gating device 27. To relieve the thyristor 20 from heavy current transients at switch-on a pulse generator 25 is provided whereby the thyristor 24, and hence the thyristor 20, is constrained to switch-on at the zero points of the output voltage of the rectifier 13. To prevent wastage of energy when no cooking pan 23 is placed on the heating element 22 a detecting device 10 is provided. The device 10 is provided with a comparator 32 wherein a voltage dependent upon the current taken by the element 22, and derived by way of resistors 33, 34, is compared with a reference voltage obtained by means of a current transformer 30 and a full wave rectifier 31. The comparator 32 produces an output only in the absence of a pan 23 and this output enables a generator 36 to produce pulses which cause the gate 27 to block the firing pulses to the thyristor 20 thus de-energizing the element 22. A variable inductor 35 is provided to enable variations to be made between the pan 23 and the element 22 and the control therefor can be coupled to the means for varying the resistor 33 in correspondence thereto. The apparatus serves to reduce the heat generated in small articles which may be placed inadvertently in association with the heating element 22. In a further embodiment the primary winding for the current transformer in the detecting device 10 is formed by the connection from the thyristor 20 to the conductor 15.

Abstract: 901,446. Printing surfaces. FRY, W. A. March 22, 1960 [Feb. 12, 1959], No. 4943/59. Class 100 (2). An electrotype printing plate is produced by forming a shell by electrodeposition on a mould, spreading a thermosetting plastic paste over the rear surface of the shell and allowing the backing to set. The mould is prepared in known manner for deposition of a copper shell. The mould is then placed in a case in a vat until the shell is thick enough. The mould and shell are removed from the case and placed in a casting base. A thin layer of resin, e.g. epoxy resin, is brushed on to the surface of the shell to eliminate air traps and then more resin is spread on to the copper shell and smoothed by a straight edge. Curved thickness control bearers control the thickness of the plate. Surplus paste is displaced by a roller travelling over the backing. After initial setting of the resin, the backed shell is removed and pressed on to a thin curved metal baseplate previously coated with resin to act as a cement. Setting of the resin may be completed in a warm chamber. Alternatively, the shell may be deposited on a flat, instead of a curved, mould and the shell is then curved and backed with thermosetting plastic. Epoxy resins used for the backing are cured or hardened by reaction with amine or acid anhydride catalyst hardeners. In the case of polyester resins, styrene may be used as the hardening agent.
