Abstract: 1,063,142. Computer programming arrangements. BURROUGHS CORPORATION. Nov. 13, 1963 [Nov. 30, 1962], No. 44731/63. Heading G4A. A computer module comprises means for executing commands involving selectively no address, one address, two address and three address programming, and means in electrical relationship to the first means for selecting no address, one address, two addresses and three addresses for providing variable length instructions. The Specification describes in detail the operation of the module showing how relative addressing, indexing, and memory protection (i.e. the prevention of overwriting in blocks of main memory already allocated to other purposes) are carried out, using indexes and housekeeping data stored in the modules' own thin film storage unit. It also describes the floating point operations. The word format is shown in Fig. 5 (not shown). A data word consists of 48 bits, one of which in a binary data word indicates the sign. If alphanumeric data is stored, each character uses six bits, while for floating point operations a 12-bit exponent (including sign bit) and 36-bit mantissa (including sign bit) is employed. Instructions use a syllable format, with up to 7 syllables of 12 bits per instruction. The first syllable (Fig. 7, not shown), is an operation syllable with a 6-bit instruction code part and three tags. These tags indicate whether the operand addresses are indexed or not, or whether the operand is to be taken from (or returned to) stack. If indexing is used on an operand, its first syllable will be the address of the index, and if necessary further index syllables may be used (enabling a multi-level index system). The carrying out of the possible machine orders is described and illustrated in detail by the aid of flow sheets.

Title: Improvements in the treatment of napped acrylic fabrics
IPC: D06C29/00
Filed: 1962-11-30
Abstract: 1,003,697. Treating polyacrylonitrile napped fabrics. MONSANTO CO. Nov. 30,1962 [Dec. 1, 1961], No. 45417/62. Headings D1L and D1P. The pilling resistance of a napped fabric composed at least in part of acrylic fibres containing at least 85% by weight of polymerized acrylonitrile is improved by continuously feeding it through an application zone where it is treated with a finely divided stream of a solution of an aliphatic cyclic carbonate derived from a 1, 2-, 2, 3- or 1, 3- dihydric aliphatic alcohol having not more than four carbon atoms in its alkylene radical, leaving the solution on the fabric for a time sufficient to permit partial softening of the nap fibres, continuously feeding the fabric through a heating zone to evaporate the solution from the fabric so that the nap fibres are banded at their points of intersection and then cooling it to a temperature below 66C. before subjecting it to laterally applied pressure. Aqueous solutions containing 2-50% by weight of the cyclic carbonate which may be ethylene carbonate, propylene carbonate, trimethylene carbonate, 1, 2-butylene carbonate, 1, 3-butylene carbonate, 2, 3-butylene carbonate or isobutylene carbonate, may be used. The cyclic carbonate solution may be applied to the fabric as fine particles in the form of a mist, fog or cloud in a propelling gas at a temperature of 18-66C. 1-5 cc of the cyclic carbonate may be applied per square metre of the fabric and the fabric may then be heated to 107-143C. to evaporate the solution. The fabric may be rapidly cooled to below 66C. by treating with cool air for 5-10 seconds. Napped woven, knitted, felted, braided or tufted fabrics comprising acrylic fibres alone or in admixture with wool, cotton or viscose rayon fibres may be treated. The acrylic fibres may be made from copolymers containg 94% by weight of acrylonitrile and 6% by weight of vinyl acetate or methyl acrylate or from polymer blends containing (a) a copolymer of 94% by weight of acrylonitrile and 6% by weight of vinyl acetate and (b) a copolymer of 50% by weight of 2-methyl-5-vinyl pyridine, the blend containing 6% by weight of the methyl vinyl pyridine. In the drawing the cloth 10 is withdrawn from container 11 and passed to scray 13 on which it is forwarded in small folds and passed between tension bars 14 and 15 to the chamber 16 where it is sprayed with the cyclic carbonate solution by nozzles 28 and 30 supplied with the solution by headers 24 and 25 and conduits 26 and 27 and connected to gas supply headers 31 and 32. Pans 35, 36 and 40 receive solution impinged against the cloth but not retained thereon and pipes 37 and 38 supply gas under pressure to provide an up-draft or air curtain so that a minimal amount of solution will pass below the pipes. The cloth is heated in chamber 17 by banks of infra-red radiant heaters 45 and cooled in chamber 18 by means of cool air supplied by ducts 48 and 50. The cloth is passed throuth plaiter 58 reciprocated by cam driven means and collected in container 60 in the form of folds or plaits.

Title: Method and apparatus for generating power in a vapor generator-turbine plant
IPC: F22G5/20
Filed: 1962-12-04
Abstract: 965,180. Regulating steam temperature in boilers. COMBUSTION ENGINEERING Inc. Dec. 4, 1962 [Dec. 27, 1961 (2)], No. 45753/62. Heading F4A. In a unit power plant operating with double reheat the high and low pressure reheaters are arranged serially with respect to the combustion gas flow and reheat temperatures are regulated over a wide load range by adjusting the location of the combustion zone in the furnace and by regulating the quantity of flue gas recirculated to the furnace whereby the increase in the percentage of total heat absorbed by one reheater relative to that absorbed by the other as the load decreases and vice versa is compensated. In the form shown the boiler, which supplies steam to a turbine 48, has an upright furnace 10 fired by tilting burners 72, gases flowing past a final superheater 44 to a lateral pass 14 locating the second section 58 of the high-pressure reheater and the low-pressure reheater 66 to a downpass 16 in which are disposed a primary superheater 38, the first section 54 of the highpressure reheater and an economizer 20. A fan 74 withdraws cooled flue gas from the bottom of the downpass and discharges it into the lower part of the furnace through a duct 78 controlled by a damper 88. The tilt of the burners and the setting of the damper 88 are respectively controlled in dependence on the temperatures of the low-pressure and high-pressure reheated steam. At maximum load the reheat temperatures are at the desired values. With a decrease in load, when the high pressure reheater requires a greater proportion of the total heat absorbed relative to the demand of the lowpressure reheater to maintain the desired values, the burners are automatically tilted downwards and the gas recirculation increased, the effect being to decrease the heat absorbed by the low-pressure reheater 66 and increase that absorbed by the high-pressure reheater section 54 which constitutes the major proportion of the heating surface of this reheater, so maintaining the steam temperatures at the desired values. In a modification, the high-pressure reheater is arranged upstream of the low-pressure reheater and the controls actuate burner tilt and recirculated gas damper setting in inverse manner.
