Abstract: 902,913. Sensing record cards. GENERAL ELECTRIC CO. May 30, 1960 [July 2, 1959], No. 19030/60. Class 106 (1). A photo-electric arrangement for reading a record card having rows and columns of lighttransmitting areas, for example, perforations, comprises selectively operable lamps individually associated with, and transmitting light to, a respective row, a plurality of photo-electric cells, one allocated to each column of the areas, a number of light-directing elements, each of which is associated with a respective photo-cell and a corresponding column of said transmitting areas or holes with said lightdirecting elements operating in conjunction with the selectively operable lamps to direct light passing through columnar light-transmitting areas in selected rows of the areas to said respective photo-cells and means to detect the response of said photo-electric cells as a result of light incident thereon. A hinged cover 1 carries twelve arcuately-disposed elongated lamps L1 . . . L12 corresponding to the length of the record card 7, with 12 rows and 80 columns of selective perforations, and disposed in separate light-directing channels formed by partition members 20, 21. . .32, 33. The casing 3 has a top portion 2 holding the card 7 and is provided with partition members 20, 21... forming 80 compartments in which 80 photo-cells 16, forming a group 15, are centrally located in their lower surfaces. A number of columns, for example 1 to 40, have lightdirecting devices 27, e.g. rods of lucite, associated with the first row of perforations and passing light to associated photo-electric cells 26 for those columns of the first row which have perforations. The partitions 32, 33 associated with the lamp L1 have reflecting surfaces 34, 35 to direct light normally on to the upper end surfaces of the lightdirecting devices 27. The forty cells 26 forming group 25 are connected via forty amplifiers to output terminals 47 when switch 51 is in the closed position, and the first forty cells 16 of group 15 are connected, when switch 41 is closed, to transistor amplifiers and forty output terminals 46. The second group of forty cells 16 of group 15 are connected to a further forty output terminals by means of a third switch indicated in Fig. 6 (not shown). The lamps L1 ... L12 are illuminated in succession and the lamp L1 is formed of two sections of which the first half, associated with columns 1 to 40, is energized by the secondary winding of a transformer To when the operating switch Sm is closed. The second half of L1 is energized when a switch S1 is closed, and the remaining lamps L2 ... L12 are individually energized in sequence by successive actuations of switches S2 . . . S12. The arrangement permits the reading of row 1, rows 2 to 12, or rows 1 to 12 of columns 1 to 40, with or without the reading of rows 1 to 12 of columns 41 to 80, in which the reading of row 1 would not have the separate significance as for columns 1 to 40, and would control a photo-cell 16 associated with a terminal 46 common to all the rows of a column.

Title: Method of improving the processing of refined chemical pulp into viscose by adding anion active agents
IPC: D01F2/08
Filed: 1943-11-24
Abstract: A surface-active agent of the anion active class, preferably one which has substantially the same degree of solubility or insolubility in caustic soda solutions of both mercerizing strength and the more dilute strengths normally present in viscose, is incorporated in the cellulose material or the reagents used at any stage in the production of alkali cellulose or cellulose xanthate prior to completion of xanthation, in an amount of 0.01-0.15 per cent of the weight of the dry cellulose pulp, refined chemical pulp containing not more than 0.15 per cent other extractable matter being used as the starting material.  The anion active substance may be added to the cellulose pulp prior to sheet formation, or it may be applied to the pulp sheet.  It may be added to the mercerizing lye or may be mixed with the alkali cellulose during the shredding operation.  The presence of the anion active substance facilitates the operations of shredding, xanthating, dissolving and filtering.  Further, if filaments of subdued lustre are required, the anion active substance facilitates dispersion of the matting substance, e.g. mineral oil. p Smaller quantities of carbon disulphide are required for the xanthation, and the time required for ripening the viscose is reduced.  Anion active substances, insoluble in 18 per cent and 5-8 per cent caustic soda solutions, which may be used, are: soaps such as sodium oleate, sodium rosinate, and other alkali salts of fatty or resinic acids; soap-forming substances such as coconut oil, linseed oil, soya bean oil, cotton seed oil, glycol dioleate, oleic acid, rosin, or tall oil; alkyl aryl sulphonates such as the substances known as "Alkanol B," "Nacconol N.R.," and "Santomerse 3"; sulphated fatty alcohols such as sodium lauryl sulphate; sulphonated ethers such as "Tensol 52"; sulphonated naphthenic acids; phosphorated oils such as phosphorated castor oil.  Anion active substances which are soluble in both 18 per cent and 5-8 per cent caustic soda are: highly-sulphonated animal or vegetable oils such as the sulphonated castor oil sold under the Registered Trade Mark "Prestabit V"; sulphonated ethers such as the substance sold under the Registered Trade Mark "Triton 720."  The viscose obtained may be used in the production of artificial silk, staple fibre, transparent films, or sausage casings.

Abstract: 1358682 Reactors ENGLISH ELECTRIC CO Ltd 26 July 1971 [24 April 1970] 19777/70 Heading G6C  In an advanced gas cooled nuclear reactor, the moderator is cooled and the reflector bricks provide gas pressure equalizing manifolds, surrounding the fuelled region of the core, to prevent the occurrence of localized forces caused by asymmetric coolant flow when a fuel stringer is removed from a fuel channel. Coolant flows upwards through the apertures, 29, and the neutron plug, 30, to the fuel stringer sleeves, 34. The heated gas flows into the chamber 36 through the ports, 35. Moderator coolant flows upwards round the moderator to space, 37, and downwards through the inter-column spaces, 38, from which it flows through the ports, 33, into the fuel channels. The reflector bricks, 16, are formed with recesses, 43, which together constitute ring-shaped manifolds which surround the core and which interconnect the spaces, 38, to equalize coolant pressures within the core when a fuel stringer is removed from the core. This compensates for the "edge effect which would occur due to asymmetrical coolant flow due to a fuel stringer being removed from a channel at the edge of the core. Annular recesses 49 connect the spaces, 38, horizontally.
