IPC: G03F7/095
Abstract: 1,053,112. Thermographic materials; making lithographic plates. A. B. DICK CO. Feb. 18, 1964 [Feb.18, 1963], No.6721/64. Headings G2C and G2M. A thermographic material comprises a base sheet having a water-wettable surface carrying a coating which can be washed off with water and which contains a uniformly distributed substance convertible to water-repellent areas when exposed to a heat image, the base sheet and coating being substantially transparent to both ultraviolet and infrared radiation. The base sheet may be a cellulose triacetate support subbed with an acrylic modified vinylidene chloride containing colloidal silica, clay and talc and the coating may be cane wax dispersed in partially hydrolysed polyvinyl acetate and may contain dyestuffs. An imaged lithographic offset master is made by bringing an original having an infrared-absorbing image into surface contact with the above thermographic material, exposing it to infrared and washing off the non-image areas of the thermographic material to give a positive water-repellant image on a water-wettable surface, treating the said imaged material with an aqueous solution of a compound which blocks the transmission of ultraviolet radiation, such as metanil yellow, and exposing to ultraviolet through the thus-formed negatively imaged material an ultravioletsensitive photolithographic plate, such as an aluminium plate sensitized with a resin-forming diazo compound, which forms an ink-receptive, water-repellant image in the areas exposed to  ultraviolet, which image corresponds to the image of the original. The above procedure may be modified by using the ultravioletblocking solution to wash off the non-image areas of the thermographic material.

Abstract: 1,053,952. Magnetic storage apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Jan. 23, 1964 [Feb. 6, 1963], No. 4817/63. Heading H3B. In a shift register comprising a magnetic thin film strip having its magnetization initially in a single direction along a longitudinal easy axis, and in which the direction of magnetization of a small area of the strip is reversed by an input signal and is then moved progressively along the strip by alternating control pulses applied to a pattern of shift control conductors, a continuously biasing magnetic field is applied to the film which tends to maintain the magnetization in its initial direction. As shown in Fig. 2, the thin film strip 2 is supported on a substrate, and adjacent input and output transverse conductors 7, 8 are provided near opposite ends. The strip is biased longitudinally by a coil 11 connected to a D.C. source 10 and has an adjacent pattern of transverse control conductors 4, 6 in two mutually staggered layers. As in the prior art the control conductors in any one layer are connected in series alternately at opposite ends, and the small area reversed in magnetic direction by an input pulse in conductor 7 is moved towards the output conductor 8 by alternating pulses B, C, Fig. 3, respectively applied to the two control conductor layers. The movement of the small area is effected by current in the control conductor adjacent the forward edge of the area which causes a local reversal of the film magnetization to extend the area, and by current in the control conductor adjacent the rearward edge which causes a local restoration to the initial magnetic state to reduce the area. The action of the bias is to ensure that the local restoration is more positive by assisting the action of the control current at that position, while the reversal of magnetization to extend the area is restricted to the vicinity of this area by the action of the bias in reducing the effectiveness of the control current.

In a nuclear power plant which uses the reactor coolant gas, C0 2  to heat the turbine working fluid, the latter may be either steam or freon gas. In one embodiment, Fig. 2, the reactor coolant gas heats two separate supplies of water, the hotter of which is received in the lower reservoir 5, Fig. 2, while cooler enters the upper chamber 3. The flexible partition 6, separates 3 and 5, the reservoir 5 is thus under pressure and vapourization of the contained water is prevented. The water from 3 and 5 is vapourized in the expansion chambers 7 and 10 which supply the turbines 12 and 13 respectively. In a further embodiment, Fig. 3, the coolant gas from reactor 15 heats feon, which is received in tanks 17 and is supplied to the turbine 19 through the expansion valves 18. Alternatively, a third heat storage medium, for example potassium and sodium nitrates or nitrites may be interposed between the reactor coolant gas and the freon.

Abstract: 1,231,110. Animal food. ROCO CONSERVEN RORSCHACH. 29 Dec., 1969, No. 63151/69. Heading A2B. An animal foodstuff containg meat, which term includes all edible flesh, for example from animals or fish, and having a water content of 10-50 wt. per cent., is preserved by saturating the meat in the non-denatured state with a concentrated solution of a sugar, and is subsequently warmed to coagulate the meat protein, at least on the outside of the meat. An emulsifier may be added before or during the treatment with the sugar solution, particularly if a fat component is present. The thus saturated and coagulated meat may be added to a dry mixture of other food components to give a balanced animal foodstuff, and the resulting mixture processed with warming to give a shapeable plastic composition.

Abstract: 1,251,263. Splicing yarn ends. W. V. WILLIAMS. 9 April, 1969 [6 Nov., 1968], No. 18278/69. Heading D1W. A method of splicing a plurality of thermoplastic synthetic yarn ends comprises the steps of clamping together spaced pairs of yarn ends and maintaining the clamped together pairs in a fixed position, and moving a radiant heating means in a path with traverses all the clamped pairs close to the yarn ends to cause fusion of the ends. Apparatus for carrying out the method comprises a support structure including an elongated track member 32, a self-propelled yarn splicing head 36 movable along the track member 32, the splicing head 36 including a radiant heating element 71, and coacting opposed yarn clamping bars 42, 43 having spaced teeth 46, 54 which hold a plurality of pairs of yarn ends in the path of movement of the heating element 71. The heating element is resiliently biassed towards the clamping bars. In operation, the trailing ends of a beam are held and severed, and are then placed with the leading ends from a full beam between the clamping bars 42, 43 so that corresponding pairs of ends are held between the teeth 46, 54. The clamped bars 42, 43 are then pivoted to bring the yarn ends into the path of the heating element which is activated, and the splicing head travels along the track 32 to weld the yarn ends. The splicing head is provided with an automatic stop when it reaches the end of its travel, and can either be manually returned to the starting position, or the driving motor can be reversed to propell the head back to the start. The splicing head is propelled by means of a driving gear engaging a toothed rack extending along the track 32.
