Patent GB-480766-A (GB)
Title: Method of producing photographic colour-screen prints on paper and other supports
IPC: G03C7/04
Filed: 1936-05-20
Abstract: 480,766. Colour photography. PILLER, F. May 20, 1936, No. 14294. Void. Convention date, May 20, 1935. [Class 98 (ii)] In making prints on multicolour - screen sensitive material by contact or projection from coloured ordinary or multicolourscreen negatives or diapositives, or coloured slides, an additional screen is used and is registered with the screen on the print material. The additional screen may be a multicolour screen ; or a black and white line screen may be used which is displaced tc uncover the different screen colours in turn for separate exposures with appropriate coloured light. As shown, for projection printing, the image of a multicolour screen a is first registered marginally with the screen c<2> of the print material c, the picture area of which is masked during this operation. The coloured original b is then projected by white light through both screens onto the panchromatic layer c<1>. If a diapositive is printed, the print is developed by reversal to a positive. The positions of screen a and original b may be reversed, and either may alternatively be placed in contact with the print material c. Printing may be effected by contact, with screen a and original b laid one above the other against the print material c. If as screen b, a black and white line screen is used adapted to mask all the colours except one, it must be registered in position for each partial exposure.

Abstract: 629,594. Cathode-ray tubes. POOLE, R. B. May 11, 1946, Nos. 14316 and 16722. [Class 39 (i)] [Also in Group XL (b)] A cathode-ray tube for a colour television system employing movable filters (see Group XL (b)) is provided with photo-electric auxiliary electrodes PEC providing signal currents which, when amplified, serve to move the filters in synchronization with the scanning beam. The auxiliary electrodes are excited by the light from the fluorescent screen when the beam reaches their neighbourhood. The mirrorbacked fluorescent screen MFS is supported on a re-entrant stem 10 rising from a base-member D on which is clamped by clamps 16 the bodymember B. Other re-entrant stems 12, 14 carry the electron gun electrodes. A re-entrant portion 73 enables the deflecting coil M2 to be got near the beam. The transmitting tube may have a mosaic screen fitted with similar auxiliary electrodes, Fig. 15 (not shown.).

Title: Improvements in or relating to range clocks or keepers for use in gun fire control
Filed: 1921-05-23
Abstract: 188,694. Vickers, Ltd., and Gray, P. W. May 23, 1921. Sights.-Range clocks or keepers, of the kind which include adjustable members set in accordance with the speed and course of the target and in accordance with the speed and course of " own " ship adapted to adjust the available speed element of the mechanism so that the apparatus indicates the range for use with the gun sight or director, are carried by a training portion of the gun sight or director sight and drive a pointer contiguous to a pointer driven by the sight-elevating mechanism. Alternatively. the range-clock may operate a pointer which is also under the influence of the elevating mechanism. A shaft A rotated by the rangeclock drives a pointer A and the handle B drives a pointer B and also operates the elevating mechanism of the sight B. The handle B is rotated to maintain the pointer B opposite the pointer A. Corrections are introduced by means of differential gearing operating upon the pointer B. When used in conjunction with a director sight, the range may be transmitted to the gun stations by an electrical switch. Specification 189,157 is referred to.

Title: Embossing of fabrics
Inventor: WOOD FRED
IPC: B44C1/24
Filed: 1958-05-06
Abstract: 920,442. Embossing; stencilling. BRITISH RAYON RESEARCH ASSOCIATION. May 5, 1959 [May 6, 1958], No. 14427/58. Class 100 (2). In a method of embossing a fabric by passing it between an embossing roller and an impression roller, stencil means passes over one roller and is disposed between the fabric and one roller surface. A heated, engraved, metal bowl 11, Fig. 3, coacts with a resilient cotton bowl 12. An endless stencil band 14a, which may be made from ragboard, Manilla hemp paper or wood pulp paper, is passed round the bowl 12 and a tensioning roller 13. The fabric 15 passes between the stencil 14a and the metal bowl 11 whereby the areas of the fabric adjacent to the cut-out parts of the stencil receive no embossment while the ground of the cloth is embossed. In a modification, the stencil is fed round the bowl 11 and the fabric passes between the stencil and the cotton bowl 12 whereby the embossment is effected only on those parts of the fabric adjacent to the cut-out parts of the stencil. The stencil may be in the form of strips 34a, 34b, 34c Fig. 5, passing round either the bowl 11 or the bowl 12. The process may be used on fabrics made from thermoplastic fibres e.g. nylon "Terylene" (Registered Trade Mark) " Seraceta " (Registered Trade Mark) filament acetate satin, cellulose acetate, and on non-thermoplastic fabrics e.g. viscose rayon, which are first padded with a suitable resin which is cured after the embossing. MoirÚ, cirÚ, crepe and schreiner effects may be produced in this way. The process is also applicable to the embossing of leather, leathercloths, polyvinyl chloride and coarse, thick paper.

Title: Improvements in and relating to electric control systems
IPC: H02M7/06
Filed: 1937-05-27
Abstract: 501,831. Automatic control systems and regulators. BRITISH THOMSONHOUSTON CO., Ltd. May 27, 1937, No. 14739. Void. Convention date, May 27, 1936. [Class 38 (iv)] In systems in which a main source of current 1, 1, Fig. 1, supplies a load 3, 3 and charges a battery 2 and in which the battery supplies the load when the main supply fails, the voltage of the supply is controlled by a coil with two parts 5, 6 in opposition, one part 6 being in the battery circuit and the other 5 in the load circuit. An impedance 7 across the load circuit limits the charging rate of the battery when there is no load. In the application shown in Fig. 5, an A.C. source 1 supplies the battery 2 and the load 3 through a combined transformer and regulator and a rectifier 10. The core of the transformer has a transverse leg on which is wound the saturating winding consisting of the opposed control coils 5, 6 in the load and the battery circuit respectively. An additional saturating winding 16 may be provided. In a modification, Fig. 6 (not shown), the transformer functions as an auxiliary backing transformer, the primary winding 14 being connected across and the secondary winding 15 in the supply circuit. Tappings on the auto-transformer 8, Fig. 7, may be changed by an electromagnetic relay 19 controlled by the opposed coils 5, 6. The impedance 7 is switched out or in according to whether current is or is not flowing to the load 3 through the relay 22. In a modification, Fig. 8 (not shown), a carbon pile resistance 24 replaces the tap changing device. The saturable control reached in the system shown in Fig. 9, regulates the pulsating current flowing through the windings 9 to the rectifier 21, in accordance with the degree of saturation due to the current in the opposed control windings 5, 6. In a modification, Fig. 10 (not shown), an additional control is provided responsive to the state of charge of the battery. A relay 25 in the battery circuit operates a tap changing switch 26 for the saturable reactor.
