Title: Improvements in or relating to the production of copies from multi-colour screen cinematograph films
IPC: G03C7/04
Filed: 1934-03-01
Abstract: 434,434. Colour photography. HARRISON, G. B., 23, Roden Street, Ilford, Essex. March 1, 1934, No. 6642. [Class 98 (ii)] In order to produce a large number of copies of a multicolour-screen master negative or positive without undue damage to the master, sets of intermediate colour-separation prints are made from the master on plain sensitive material, and from each set finished copies are prepared by printing the components, each with light of the appropriate colour, in register on multicolour-screen sensitive material. In either or both printing stages, the images may be slightly diffused in known manner to compensate for lack of registration of the screen elements on the master and the final copies. The separation prints 2, 3, 4 may be produced by contact printing from the master 1 as shown in Fig. 1, using parallel printing beams G<1> G<2> of the appropriate colours which are dispersed by prisms 5 and lenses 6 to form pure spectra at 7 from each of which unwanted light is masked by an appropriate masking plate produced as described in Specification 417,860. Instead of dispersing and masking the beams, a sharpcut filter may be inserted in the path of each beam. The light beams are concentrated on their respective gates by lenses 8, and registration is affected by the sprockets 10. Similar apparatus is used for printing the final copy from the intermediate separation prints. Advantage may be taken of the fact that the light beams at the printing gate are not parallel to produce slight diffusion of the image if provision is made for a slight separation between the films in the gate. To ensure that the correct set of images is printed in each image space, a perforation is made at the beginning of each of the printing and print films in appropriate position, and these perforations are registered by spring pins 16 before printing is begun.

Title: Improvements in or relating to multi-colour printing processes employing half-tone negatives or positives
IPC: G03F3/02
Filed: 1933-03-04
Abstract: In a process of making correctly coloured printing formes for multicolour printing in which a set of positive or negative half-tone part-pictures is produced from the original and the pictures retouched to secure correct colour values, each negative or positive part-picture is produced on a separate light-sensitive layer applied to a white substratum carried by a non-expansible body.  The carrier may be a metal or glass plate and the light-sensitive layer and white substratum formed by using a light-sensitive paper.  In this case an intermediate layer e.g. of water glass or of gelatine hardened with chrome alum is applied to the carrier and the paper secured thereto by a adhesive consisting of spirit varnish with the addition of gum elemi.  The surface of the glass may also be roughened to secure a better adhesion and a framing of paper or film applied to the edges with gum or glue to prevent the sensitive paper becoming detached.

Filed: 1961-02-23
Abstract: 914,037. Analogue calculating devices. JERIE, H. J Feb. 23, 1961 [Feb. 26, 1960], No. 6686/61. Class 106 (1). An analogue device for use in the adjustment calculation of a trilateration network comprises a base member having a smooth flat surface, marking devices, Fig. 3, slidingly arranged on the base member and having hollow studs, 1, perpendicular to the surface, and distance-rods, each of which comprises a rigid rod 7, Fig. 1, and, slidingly arranged thereon, two fixing elements, one of which, 9, is restricted in its movement by two elastic members, 13, and the other of which, 8, is fixed, and both being provided with a bore which slidingly fits on the studs. The known points in the network are represented by pinning corresponding marking devices to the base member. Distances between the fixing elements 8, 9 of the distance rods are set by means of a setting-rule, Fig. 5, provided with a scale calibration 24, heads 21, 22 and a slidable setting element 25, and the helical springs 13 are initially set up in an unstressed condition by means of adjustable collars 14. The base member holding the fixed studs, distance-rods and freely slidable studs representing unknown points, is then vibrated and the equilibrium positions of the unknown points are subsequently marked by pinning needles through the studs. The discrepancies between the values of the distances measured in the field and the approximate values are then introduced into the rods and the base member is again vibrated. The difference between the two equilibrium positions of each slidable stud represents the adjustment required in the approximate co-ordinates of the unknown points. A detailed example of the use of the device in connection with mapping scales, is given in the Specification.

Title: Improvements relating to multi-layer sheet materials
IPC: D06M17/02
Filed: 1944-04-11
Abstract: 581,580. Compound sheet materials. BRITISH CELANESE, Ltd. April 11, 1944, No. 6703. Convention date, April 8, 1943. [Class 140] Waterproof or gasproof compound sheet material comprises a central thermoplastic film or foil, a plasticized fabric containing both non- thermoplastic and plasticized thermoplastic yarns on each side of the film or foil, and outer non-thermoplastic, or unplasticized thermoplastic fabric layers, all adhesively joined together. The thermoplastic material for the film or foil and the thermoplastic yarns in the fabrics may be a polyvinyl resin, a synthetic linear polyamide derived from amino acids or from diamines and dicarboxylic acids, an organic cellulose derivative such as cellulose acetate, propionate, or butyrate, ethyl or benzyl cellulose. The non- thermoplastic yarns employed in the fabrics may be cotton, linen, or regenerated cellulose. The film may contain a plasticizer such as triphenyl phosphate, dimethyl diethyl, or dimethoxyethyl phthalate, dibutyl tartrate, or triacetin. The plasticizer applied to the fabrics adjacent to the film may be those already mentioned and also ethyl paratoluene sulphonamide, monomethyl xylene sulphonamide, triethyl citrate, or mixtures. The plasticizer may be applied to the fabric as a solution in a volatile solvent such as benzene, methyl or ethyl alcohol. The absorption of plasticizer may be accelerated by the use of a penetrating agent such as Turkey red oil, xylene, toluene, monopol oil, pine oil, sulphonated pine oil, cyclohexanol, cyclohexanone, diacetin, tetrahydronaphthalene, or mixtures of two or more of these materials. The treated fabric may be aged, treated with methyl or ethyl alcohol, and again aged. The fabrics may be woven, knitted, knotted, or netted. The outer fabrics may be of cotton, or cellulose acetate. The layers are united with the aid of heat, pressure, and, if desired, moisture or a solvent. One of the outer layers may be made water-repellent, e.g., by treatment with an aluminium acetate-wax emulsion. The product may be used for water-bags, clothing, knapsacks, and tents. Specification 452,298 is referred to.

Title: Improvements in or relating to methods of detecting flaws in solid material and of apparatus therefor
IPC: G01N27/20
Filed: 1961-02-23
Abstract: 1,017,061. Testing materials for flaws. CENTRAL ELECTRICITY GENERATING BOARD D. H. LUCAS, H. L. CARSON and R. C. WRATTEN. May 23, 1962 [Feb. 23, 1961], No. 6712/61. Heading G1N [Also in Division H4]. A solid material is tested for flaws, using a flaw detector giving an output signal dependent on the presence of a flaw, by applying a variable stress to the material and detecting the variation in output signal corresponding to the varying stress. Rod 10 is fixed in insulating clamps 11, 12, one of which is driven by a moving coil vibrator 14. Current is passed through the rod between contacts 21 and 22, and the potential drop between contacts 24 and 25 is applied through filter 26 to an AC amplifier 27, phase sensitive detector 28 and meter 29 (Fig. 2 not shown). Transverse cracks in the rod are modified at the vibration frequency and the output component having this frequency is detected. Contacts 24, 25 may be placed closer together and arranged to be moved over the surface of the rod to locate a flaw. A weld joining two magnetic tubes may be tested by placing a coil around the tube on each side of the weld, detecting variations in the leakage flux at the weld using a search coil, and detecting variations in output of the coil at the vibration frequency. A similar arrangement for a non-magnetic tube comprises a search coil arranged in a bridge circuit and energized to induce eddy currents in the weld, variations in the impedance of the search coil being detected. The varying stress may be an impulse or a periodically repeated impulse, and may be a tensile, torsional, or bending stress. The applied stress may be similar to the stress expected during use of the sample, and may be applied to a part or the whole of a body. The stress may be produced by an unbalanced rotor. A pressure vessel may be tested using an oscillating piston acting on hydraulic filling the vessel. An ultrasonic flaw detector arrangement is also described (see Division H4).

Title: Improvements relating to direct-action fuzes for projectiles
IPC: F42C15/24
Filed: 1953-03-11
Abstract: 725,967. Projectile fuzes. AKTIEBOLAGET BOFORS. March 11, 1953 [March 14, 1952], No. 6717/53. Class 9(1).  Direct action projectile fuze has a casing 1 into which is screwed a tubular member 2 containing a detonating charge 3. Near the mouth of the tube 2 a cylindrical member 4 is arranged to rotate about an axis transverse to the axis of symmetry of the fuze. Extensions at the ends of the member 4 form pivots 5, 6 (not shown in Figs.), and a diametral passage 7 in the member is filled with a primary charge, this passage being out of alignment with a striking pin 9 which is tapered at each end. A spring 10 bears against a collar 11 on a sleeve 12 which supports a second sleeve 13 having one or more recesses 14 in its forward edge. A protective casing 15 has a reduced portion extending between the sleeve 13 and the tube 2, this portion being provided with one or more through holes 16. Balls 17 in these holes engage recesses in the tube 2. Further balls 20 extend into recesses or a continuous groove in the casing 15 and recesses 21 in the tube 2. Longitudinal slots 22 in the casing 15 receive the pivots 5, 6 (not shown), to lock the member 4 with the passage 7 in a horizontal position. On firing the projectile, the acceleration produced causes the sleeves 12, 13 to set back and stress the spring 10. As the acceleration decreases, the balls 17, 20 move outwards under centrifugal force and exert pressure on the casing 1, the sleeves 12, 13 are moved forwardly by the spring 10 and the balls 20 move into recesses 14 so forcing the casing 15 upwards. The casing 15 and balls 17 are first ejected and then the sleeve 13 and balls 20. The collar 11 of sleeve 12 then abuts the pivots 5, and turns the member 4 until the passage 7 is aligned with the striker, which on impact is driven against the primer.

[Class 78 (i)] Apparatus for treating magnetisable articles such as steel sheets, comprises a plurality of trolleys linked together to form an endless chain, a facing plate on the outer face of each trolley upon which the articles to be treated are carried, an electro-magnet within each trolley, a continuous track around which the trolleys are driven, means for loading an article to be treated on to each trolley in succession at a loading station located at one position along the track, means for unloading the articles at an unloading station at another position along the track, means for treating the articles at a treating section located intermediate of the loading and unloading stations and means for energising and de-energising said electromagnets before and after treatment respectively at predetermined points along the track so that each article is magnetically held upon its trolley whilst it passes through the treating section. The Figures show the application to the electro-deposition of tin upon steel sheets in which the sheets secured magnetically on trolleys 12 linked together to form an endless chain, are passed through a bath 13 containing electrolyte and anodes 37 for the plating current. The sheets are fed one by one on to the trolleys as they pass the loading station 14 by suction cups 31 mounted on a frame 32 reciprocating in slides between the trolleys and the stack of sheets to be plated, and after passing through the bath are removed by similar apparatus 33 at the unloading station 15. Each trolley is provided with a magnetisable facing plate 21, Fig. 6, framed by a rubber strip 22, 22a on which the metal sheet is secured by eight electro-magnets 23 with windings 24 connected to terminals 25, 26 provided with collectors 27, 28 engaging resiliently with conductor rails 29, 30. Just before the trolley arrives at the unloading station 15, these collectors leave the rails whereby the coated plate may be removed by the unloading mechanism at 33. The facing plate 21 is connected to a terminal 34 provided with a collector 35 running on a conductor rail 36 whereby the sheet being treated serves as the cathode in the electrolytic cell, the rail 36 extending over the same portion of the track as the rails 29, 30. The trolleys are driven by an electric motor driving through gearing and sprockets 42, 43, a chain 44 carrying fingers engaging rods 46 co-axial with the wheels 17 of the trolleys running in channels 18. Immediately after being loaded on the trolley, the metal sheet is forced against the facing plate by a spring-pressed roller 50 with its edges resting on the rubber 22 which lies flush with the facing plate to form a substantially liquid-tight seal. Jacking mechanism 47, 48 is provided for raising and lowering the trolley track.
