Title: Improvements in and relating to the manufacture and production of artificial threads and the like articles from viscose
IPC: D01F2/10
Filed: 1940-05-11
Abstract: 541,099. Artificial silk &c. COURTAULDS, Ltd., and WHARTON, J. May 11, 1940, Nos. 8522 and 10531. [Class 2 (ii)] Artificial filaments, yarns, threads, and the like are obtained by extruding viscose into an aqueous coagulating solution of sulphuric acid and at least one metallic salt in the presence of a non-ionogenic water-soluble compound, obtainable by the action of an alkylene oxide on a monohydroxy compound containing at least 8 carbon atoms in the chain. The non-ionogenic compound may be added to the spinning solution or to the co-agulating bath. It may be a condensation product of ethylene oxide with an aliphatic acid or alcohol, e.g. oleyl, lauryl, or cetyl alcohol. The monohydroxy compound may be saturated or unsaturated and it may have a straight chain or a branched or closed chain. It may be an alcohol, phenol, or carboxylic acid. The presence of the alkylene oxide condensation product during the formation of the filaments reduces the tendency of the spinning orifices to become clogged. In an example, viscose is extruded into a co-agulating bath. comprising dilute sulphuric acid, sodium sulphate, glucose, zinc sulphate, and a watersoluble condensation product of ethylene oxide and lauric acid. Specification 380,431 is referred to. One of the Provisional Specifications refers also to the use of other compounds containing hydrophobic groups and in particular to a water-soluble condensation product from pentaglycerol and lauric acid.

Abstract: 545,140. Photo-electric indicating devices. BRITISH THOMSON-HOUSTON CO., Ltd. July 11, 1941, No. 8811. Convention date, July 13, 1940. [Class 40 (iii)] A photorelectric apparatus for detecting the position of an edge 10a of a body 10 or measuring the lateral deviation of that edge comprises a lamp 17 projecting a beam of light on a galvanometer mirror 16 which reflects the light past the edge 10a to a photo-electric cell 13 connected to an amplifier 15 the output of which is fed to the galvanometer 12b in such a way that lateral deviations of the edge 10a produces a following-up deflection of the mirror 16, the output current operating the galvanometer and measured by an instrument 26 being therefore an indication of the lateral position of the edge 10a or a measure of its lateral deviations. In a modification, opposite edges of a body are simultaneously examined by photo-electric devices as above, but the two amplifiers have a common return lead in which the measuring instrument is disposed and therefore gives an algebraic sum of the two currents i.e. a measure of deviations of the body from a given width.

Abstract: 848,338. Photo-electric apparatus. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. March 22, 1957 [March 23, 1956], No. 9448/57. Class 40(3). [Also in Groups XIX, XXXVI and XL(a)] A data storage member 1 is combined with a photo-resistor which comprises a layer 2 of silicon provided with horizontal and vertical conductors 4, 5 on opposite sides thereof, the whole being supported on a pure silica plate 3. The data storage member 1 may be a perforated self-supporting plate as shown, a punched card, a photograph or a metallic layer which is photoetched to provide a data pattern. The photo-resistor may be made by oxidizing niobium pentabromide and thorium tetrachloride which have been deposited on the silica plate 3 to form the conductors 5, depositing a film 2 of silicon formed by reducing silicon tetrachloride with hydrogen at high temperature and then depositing the conductors 4. If desired an electroluminescent layer may be applied to the silicon film 2 before applying the conductors 4, by transferring an alloy of for example zinc and copper by an ionic exchange in an atmosphere of oxygen. If voltages are applied to the conductors 4, 5, a current will flow through a load resistance connected to one of the conductors at each point where there is a hole in the storage member 1 when light from a source 6 falls thereon. In one use of the apparatus, Fig. 4, the conductors 4 are sequentially activated by connection with a pulse distributer 11 through triode tubes 12 and the conductors 5 are connected to input terminals 15 through triode tubes 14. When during a pulse distribution, one of the conductors 5 is activated, the data stored in that line is transmitted as a sequence of pulses to a transformer 17 and output line 18. In another use of the apparatus, Fig. 5, as a word comparator, all the conductors 5 are connected through resistances 21 to a battery 22 and all the conductors 4 are connected through bistable circuits 19 to input terminals 20 and through resistances 25 to a current source. The output at 24 will remain steady as long as there is coincidence between the data in the storage device and the input at terminals 20, but will fall wherever there is non- coincidence. The output at 24 may be applied to the input terminals 15 in the Fig. 4 arrangement and this combination may constitute a code converter.
