[Class 98 (ii)] Photographic material comprising superposed silver halide emulsion layers differentially sensitized for different regions of the spectrum and each containing colour-forming components adapted to react with a diamine or aminophenol developer to produce differently coloured images in the different layers is developed with a developer incapable of affecting the colourformers, the unaffected silver halide is removed, the silver images converted into developable silver salt images and the layers re-developed in a developer, the oxidation products of which react with the colour-formers in the layers to produce differently coloured images therein. The material may comprise three layers on one or distributed between two sides of a support. Decolourizable filter layers and an anti-halation layer may be provided. The first development may be in a metol developer. After fixing and washing, the silver images are bleached in ammoniacal potassium ferricyanide solution. After re-exposure to light, if necessary, colour development is effected in a diethylparaphenylenediamine developer. The material may comprise more than three layers, and one of the emulsion layers in either three- or four-layer material may be an ordinary emulsion not containing colour formers. The image in this layer may be coloured by any of the known processes, including the method of colour development employing a colour-former in the developer. The colour-formers may be of the kind in which diffusion is minimized. Specifications 447,092 and 458,400 are referred to.

The hood 100 is made to engage and disengage with the chisset by means a pneumatic ram 96. The chisset 2 comprises a rectangular box 4 provided with a strengthening member 14 and a lid 10 having a depending rim 12. The chisset containing pressed curds is received at one end 24 of a floor mounted frame which comprises six equal length sections through which each chisset is transported in succession, a step in removing the cheese from the chisset taking place in each section. Double chain conveyors 26 bring the chissets into the first section where it is supported on runners 32 and guide rails 34. Further movement is hindered by check arms 36 operated by pneumatic rams. When the check arms are moved out of position a pawl bar 44 operated for reciprocal movement by a pneumatic ram 48 moves the chisset out of the first section into the second when means are provided for removing the lid 10. Said means include wedge shaped members 56 secured to frame 54, the tips 57 of said members 56 engaging between the rim 12 of the lid 10 and the upper surface of member 14, thus prising the lid off as the chisset advances beneath the members 56. Means is provided between the third and fourth sections for inverting the lidless chisset, such means comprising a rotatably mounted shaft 78 extending transversely across the main frame and carrying four arms 86 at 90‹ spacing. Each arm 86 is formed from U-section metal channel formed with inwardly directed flanges. The anms are so arranged that a chisset drawn by pawl 76 from the second section into the third section is located between arms 86, the strengthening member 14 being located beneath the flanges. The arms are then rotated through 180‹, stopping at 90‹ to allow the following arms to engage the following chisset. A third pawl 92 on the pawl bar 44 disengages the chisset from its supporting arms and transfers it to the fifth section where the hood 100 is used to lift the chisset away from the cheese, which is transferred to the next section and removed by hand. An inclined gravity roller conveyor 116 at right angles to the main frame conveys the empty chisset to a conveyor for cleaning and re-use. All rams and pawls are coupled to a control mechanism which synchronises all the operations of the apparatus.

Abstract: 1,000,177. Feeding record tapes. THOMPSON RAMO WOOLRIDGE Inc. Dec. 3, 1963 [Dec. 3, 1962], No. 47769/63. Heading G5R. Since tape brakes with flat cooperating surfaces tend to grip one edge of the tape, and if the drive is started before the brake is completely released the other edge of the tape may be stretched and cause faulty reading or erasure of digital information recorded on the tape, using a rotatable cylinder as one member of the brake prevents this as the cylinder would rotate. In Fig. 3 a magnetic tape passes from a reel (not shown) between a reverse drive capstan 30 and pinch roller 32 and between a brake block 38 and its associated pinch roller 40 to a transducing head 44 and then through similar elements to another reel. Rollers 32 and 40 are normally held out of engagement with the tape by springs 35 and can be moved into engagement by solenoids 34 and 41, simultaneous actuation of the solenoids being inhibited electrically by a self-decommutating circuit. A lamp and light detector apparatus 36 is provided to detect the approach of the end of the tape, and to prevent the heat of the lamp causing expansion of the tape when it is stopped and subsequent cooling of the tape when it is re-started causing loops or bulges which might cause faulty reading or erasure. Guides 50 and 50A are adjusted on their supports 52 and 42A to provide a tape channel several tape thicknesses deep between them and the magnetic head 44.

Filed: 1975-11-27
Abstract: 1485659 Disintegrating agent for tablets DOW CHEMICAL CO 27 Nov 1975 48733/75 Headings A5B and A5E A disintegrating agent for tablets (defined as being a compressed or moulded mass of solid material comprising an active ingredient) comprises a plurality of tubules having a length of 0.5 micron to 3 mm., a substantially uniform internal cross sectional area corresponding to an inside diameter of 5 to 1000 microns and a substantially uniform wall thickness corresponding to an outside diameter of 25 to 1100 microns. The tubules are incorporated into pharmaceutical or disinfectant tablets in an amount of 0.1 to 90% by weight of the tablet. They are preferably of a water swellable material e.g. ethyl cellulose, carboxymethyl cellulose, cellulose acetate, hydroxypropylmethyl cellulose, cellulose or gelatin, and have a bulk density of 0.1 to 0.6 gms/cc. They may be produced by sub-dividing hollow fibres, e.g. those commercially available for use in dialysis produced by extrusion, melt-spinning or coating a filamentous core and then dissolving the core. The tablets are prepared by mixing the material to be formed into tablets, if necessary after wet or dry granulation, with the tubules and then compressing the mixture into tablets using a pressure which does not permanently collapse the tubules. The tubules may be dyed prior to incorporation in the tablet to give a tablet having a coloured speckled appearance. If required, the tablets may be coated to control disingration time. In the Examples, pharmaceutical tablets containing aspirin, rifampicin, and quinidine sulphate are prepared. A disinfectant tablet for use in aqueous systems such as water closets, humidifier tanks and wading pools is prepared by granulating sodium bisulphite with ethyl cellulose and spray-coating the granulate with shellac, forming a second granulate of sodium iodide and ethyl cellulose, mixing both granulates with 2, 2-dibromo-3-nitrilopropionamide and tubules of hydroxypropyl ethyl cellulose and compressing into tablets. In use the nitrilopropionamide has an initial disinfecting action which is synergised by the sodium iodide; later slow release of sodium bisulphite then detoxifies the disinfectant.
