Title: Improvements in printing or reproducing colour photographs
IPC: G03C7/04
Filed: 1934-05-02
Abstract: 437,888. Colour photography. HARRISON, G. B., and THREADGOLD, S. D., 23, Roden Street, Ilford, Essex. May, 2, 1934, No. 13311. [Class 98 (ii)] Relates to printing by contact from a multicolour-screen master photograph made on regular-pattern screen material onto multicolour-screen copy material of any pattern, using a printing light comprising a number of light sources of different colours corresponding to the screen colours, each colour having the same spectral range as, or a narrower range than, the corresponding screen colour, and consists in choosing the effective dimensions of the source of each colour in a plane parallel to the screen, and the distance of the source from the master screen, so that, having regard to the usual slight separation of the master and copy screens, the light from that source which is passed by a master screen element of the same colour spreads over an area of the copy screen substantially equal to the area of a group of colour elements forming a master screen pattern unit. The light source of each colour may consist of a single source or of several sources of that colour ; and the complete source may consist of a source of white light, or a source of light as described in Specification 417,860, with a diffusing screen or equivalent lens system, between which and the master and copy is placed a mask carrying colour filters spaced apart over its surface. If two filters of different colour overlap, a single filter transmitting both colours may be employed at the overlap. A mask for use when the master screen is of the kind described in Specification 322,432, [Class 98 (ii)], comprising red lines 1, Fig. 2, separated by alternating blue and green rectangles 2, 3, comprises an opaque sheet 8, Fig. 3, having apertures fitted with red, green, and blue filters 9, 10, 11 respectively, the filters being arranged so that the red spread the light transversely to the direction of the master screen red lines, and the blue and green spread the light both parallel and transversely to the master screen lines. Fig. 4 shows the manner in which the red sources, when placed at a predetermined distance from the master screen 12, cause light passing through a red element 14 of the master screen to spread on the copy screen 13. The filters for different colours may be of different size according to the size of the elements on the master screen ; and other slight variations may be made for the purpose of colour correction or for compensating for irregularities in the master screen element. A modified form of mask is described in the provisional specification comprising three red filters arranged in line transversely to the screen lines, three green filters arranged in line parallel to the screen lines, and a single central blue filter. Specification 374,891 also is referred to.

Title: Treatment of cotton fabrics
IPC: D06L4/70
Filed: 1960-04-14
Abstract: Sized fabrics composed entirely of cotton fibres or of mixtures of cotton fibres with other <PICT:0895721/IV (c)/1> natural or synthetic fibres, e.g. wool, viscose, rayon or nylon, are impregnated with an aqueous alkaline solution of a hypochlorite containing an alkali metal hydroxide, removed from the solution and heated at an elevated temperature for a period of time sufficient to disperse the motes and render the non-fibrous content of the fabric water-extractable, the impregnated fabric leaving the solution containing 2%-5% by weight of alkali-metal hydroxide based on the weight of the dry fabric.  The fabric, which may be woven or knitted, may be singed and washed prior to introduction into the hypochlorite solution.  The hypochlorite solution which preferably has a pH of 10-14, may contain an alkali and/or alkaline-earth metal hypochlorite in a concentration such that the solution contains 0.3-5 grams of active chlorine per litre, an alkali-metal hydroxide and 0.1%-3% by weight of an alkali-metal silicate, and may be applied to the fabric at 60 DEG F-200 DEG F. The impregnated fabric is preferably adjusted to a liquor pick up of 50%-150% based on the dryweight of the fabric and heated to 180 DEG F.-500 DEG F., e.g. by steaming at 180 DEG F.-220 DEG F. for at least 15 minutes.  The fabric may then be bleached by washing it with water and impregnating it with an aqueous solution of hydrogen peroxide, removing it from the solution and heating. The solution preferably contains less than 2% by weight of hydrogen peroxide and 0.1%-3% by weight of 40 degrees Baume sodium silicate (Na2O(SiO2)2,5) and is preferably applied to the fabric at 40 DEG F.-160 DEG F.  After leaving the hydrogen peroxide solution the liquor pickup of the fabric may be adjusted to 50%-150%, based on the dry weight of the fabric, and the fabric may then be heated by steaming for at least 15 minutes until the required degree of bleach is obtained, washed with water and dyed.  The hypochlorite solution and the hydrogen peroxide solution may contain wetting agents, e.g. arylsulphonates.  The process may be effected in the apparatus shown, in which the fabric 1 is singed by passage between burners 2 and 3, washed in bath 4, impregnated with the hypochlorite solution in saturator 10, heated with steam in J-box 16, washed in bath 22, impregnated with hydrogen peroxide solution in saturator 25, heated with steam in J-box 31 and washed in bath 36. Specification 764,483 is referred to.

Abstract: 795,327. Making springs; stamping. INTERNATIONAL ENGINEERING GENERAL RESEARCH & LICENSING CO. May 1, 1956 [May 12, 1955], No. 13370/56. Classes 83 (2) and 83 (4). [Also in Group XXXII] The invention relates to a process for making an annular spring (see Group XXXII), consisting of a number of sectors 5 defining a frusto-conical surface, and joined to each other by respective trough-like or folded portions 3. The folded portions 3 extend over only part of the corresponding radius of the spring, the remainder of the radius being slotted as shown at 7. The springs are made by first taking a strip of material and forming it with a series of folds, the axes of which are disposed transversely to the longitudinal axis of the strip, and then uniting by welding the ends of the strip to form a corrugated ring, the corrugations of which are disposed parallel to the axis of the ring. The number of corrugations of the ring corresponds to the number of folds in the finished spring. This tubular ring is then converted into the form of a ring of truncated conical shape by a stamping operation acting upon the lower edge of the ring. A final stamping operation is then carried out in dies 14, 15 (Fig. 14). The slots 7 are then formed by a machining operation.

Title: Methods and apparatus for determining distance by echo
IPC: G01S7/58
Filed: 1925-05-21
Abstract: 257,552. ressenden, R. A. May 21, 1925. Determining d i s t a n c e s acoustically. - In measuring distances or locating the position of objects by the echo method means are provided for emitting waves to be reflected, and means for receiving the waves and operating a light shutter to allow a pencil of light to fall upon a scale continuously rotating relatively to the source, of light in order to produce an indication of the distance. An oscillator 14 located in the bottom of a ship 11 produces a sound impulse which, after reflection from the bottom of the sea, is received by a microphone 16 contained in a tank 15 and shielded from the sound producer 14. The microphone 16 is in circuit with an electric instrument having a pure gold filament 41 hung between magnetic poles 40 through aligned holes through which a pencil of light from a source 54 passes. The filament then constitutes a light shutter. A disc 38 is carried on a shaft 37 driven through gears 33, 34 from a motor 32. A projecting portion 49 of the disc carries a scale and a spiral curve 50. A contact 51 on the motor shaft closes the circuit of a dynamo 39 and oscillator 14 every time the disc 38 comes to the position shown in Fig. 4, with the projection vertical and on the left-hand of the disc. An impulse is sent out, and when the echo path 46, 47 has been traversed and the receiver 16 actuated, the filament of the electric instrument is moved to allow the pencil of light to fall for an instant on the scale 49, which is made in section of different colours. The curve 50, when the depth is zero, will be seen as a short line at the top of the soale, and this line appears to move downwards a distance proportional to the depth of water. This movement may be read off in terms of depth on a separate scale. The scale is graduated up to fifty fathoms, and over this depth the light fails to strike the disc but may act on a selenium cell 35 and cause a bell to ring. The cessation of the ringing of the bell indicates that shoal water has been reached. The depth may be checked by taking a reading on a second receiver 29; or, having determined the distance of an iceberg, its direction may be found by using both receivers 16, 29. Specifications 6008/09 and 11155/10, [both in Class 40 (v), Wireless signalling &c.]. are referred to.
