Title: A process for treating cellulosic fibres
IPC: D06P1/651
Filed: 1964-11-10
Abstract: Cellulosic textile materials are creaseproofed and stiffened and their reactivity towards cross-linking agents and basic dyes is improved by impregnating them with an aqueous caustic solution and then treating them with a solution containing a hydrocarbon sultone which is an intra-molecular cyclic ester of a hydroxysulphonic acid which may be an aliphatic, cyclo-aliphatic or an aromatic acid, e.g. 1, 3-propane sultone, 1, 4-butane sultone, 1, 3-hexane sultone, benzlyl sultone, tolyl sultone and mixtures thereof.  The materials may be impregnated with an aqueous solution containing 1-30% by weight of an alkali or alkaline earth metal hydroxide, preferably sodium or potassium hydroxide, by dipping, spraying or padding at 10 DEG -40 DEG C.  Standard mercerizing procedures using 16-18% caustic solutions are suitable and the process may follow the mercerizing step directly.  The sultone may be applied as a 1-25% by weight solution in water, acetone or alcohol at a temperature of 15 DEG -90 DEG C. by dipping spraying or padding.  The solutions of the hydrocarbon sultones may contain 0.1-5% by weight of a cationic, anionic or non-ionic wetting agent.  The treated materials may be washed with water which may contain a detergent and dried at a temperature of from ambient temperature to 125 DEG C.  They may subsequently be dyed with basic dyes or padded with an aqueous solution containing 5-25% by weight of a cross-linking agent, e.g. formaldehyde, urea-formaldehyde resins, dimethylol ethylene urea, acrolein-formaldehyde resins, dicyandiamide formaldehyde resins, melamine formaldehyde resins and polyepoxides, at 20 DEG -100 DEG C. and cured at 70 DEG -175 DEG C.

Title: Logical devices
IPC: H03K19/14
Filed: 1963-11-21
Abstract: 987,359. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 21, 1963 [Dec. 31, 1962], No. 45935/63. Heading H3B. An injection laser has a plurality of input terminals and operates as a logic device. Gallium arsenide crystal 2 has an active region 6 adjacent PN junction 5, a broad area ohmic contact 1 to N-region 3, and ohmic input terminals 7A, 7B . . . 7N on P-region 4. The input terminals are arranged so that the impedance between each electrode region 8A, 8B . . . 8N and active region 6 is less than that between adjacent contact regions. This may be achieved by suitable spacing or by cutting a groove between adjacent terminals. Etching and variation of crystalline resistivity may also be used to vary the impedance between contacts. When the sum of the currents injected through terminals 7 exceeds the threshold for stimulated emission from the device the optical output exhibits an abrupt line narrowing and increase in intensity. Either phenomenon may be detected as the logical output of the device, a broad, low intensity beam representing a logical 0 and a narrow, intense beam representing a 1. A device having three inputs may be operated as an AND device if each input current lies between one-half and one-third of the threshold currents, I; as an OR device if one input is continuously energized and an input is applied to either or both of the inputs; or as a majority device if the injected currents lie between ¢I and I. In each case current flow indicates a 1 and no flow indicates a 0. Instead of associating ohmic contacts 8 with a common PN junction the input terminals may be connected to individual PN junctions positioned so as to share a common laser active region 6.
