Title: Method of creaseproofing cellulosic fabrics by wet creaseproofing followed by dry creaseproofing and the resulting product
IPC: D06M13/11
Filed: 1960-01-15
Abstract: Fabrics containing at least 10% of alkali insoluble cellulosic fibres having at least 1,8 free hydroxy groups per anhydro glucose unit are creaseproofed by (1) treating them with an aqueous solution containing a textile resin, i.e. a water-soluble, acid or acid salt catalysed material having a molecular weight of less than 1000 which will react with the cellulose molecules and which is thermosetting, and an acid or acid salt catalyst and (2) reacting them with an alkali catalysed cross-linking agent while the cellulosic fibres are in a moist, swollen condition by contact with a basic aqueous solution to produce cellulosic fibres cross-linked with linkages from 3-15 carbon atoms in length, the steps (1) and (2) being carried out in either order. Suitable textile resins are urea-formaldehyde and melamine-formaldehyde resins, methyl ethers of urea-formaldehyde resins, acrolein urea formaldehyde, cyclic ethylene urea formaldehyde, trimethylol acetylene diurea, tetramethylol acetylene diurea, methylated melamine formaldehyde, uran, triazane, tris (1 aziridinyl) phosphine oxide and epoxy resins, e.g. the diglycidyl ether of ethylene glycol, the triglycidyl ether of glycerol, and suitable acid catalysts are monoethanolamine hydrochloride, 2 amino-2 methyl-propanol nitrate, zinc nitrate, magnesium chloride and acid fluoride salts. After application of the resin the fabric may be dried and cured by heating at a temperature of 100 DEG -200 DEG C. for from 10 seconds to 30 minutes. The cross-linking agent may be diepoxybutane, the diglycidyl ethers of ethylene glycol, propylene glycol, diethylene glycol or bisphenol A, the triglycidyl ether of glycerol, epichlorohydrin, 1,2 dichloropropanol-3,1,3 dichloropropanol-2, 1-3 di-bromo-propanol-2, bis(1chloro-2hydroxy-n-propoxy)ethane, 1,4 dichloro-2,3-dihydroxybutane, divinyl sulphane, bis(vinyl sulphonyl)-methane, 1-4-bis(vinyl sulphony)butane, and octadiene-1-2, 7-8-diane-3-6. The basic catalyst employed as catalyst for the cross-linking reaction, e.g. sodium hydroxide, potassium hydroxide, sodium silicate, trimethyl phenyl ammonium hydroxide and tetramethyl ammonium hydroxide, may be applied in the form of an aqueous solution before, after or simultaneously with the cross-linking agent. The reaction of the fabric with the cross-linking agent may be effected at a temperature below 100 DEG C. Fabrics comprising cotton, linen, regenerated cellulose, cellulose acetate or partially methylated cellulose fibres alone or in admixture with glycolterephthalate, nylon or polyacrylic fibres may be treated.

Patent ES-341999-A1 (ES)
Title: Hosiery knitting with improved make up and transfer
IPC: D04B9/54
Filed: 1967-06-19
Abstract: In. knitting a stocking having a roll welt the transfer of the held course of loops to needles is begun at a point spaced circumferentially from the first stitch of the stocking. The dial of the machine includes two bolt cams 28, 34 depending into the transfer bitt butt track 26 to force the bits into and out of the needle circle respectively. The needles comprise two groups of consecutive needles having long and short butts 60, 62 respectively. Alternate, even, needles cooperate with transfer bitts. The long butt needles cooperate with short butt transfer bitts, and vice versa. The first course of the stocking is knit on odd needles only, with cam 68 acting on butts 66 of odd jacks 64. During the second half of the course cam 74 is inserted so that during the next revolution all needles take yarn, which the even needles hold until welt courses are begun, and the dial bolt cams are inserted. During the third revolution the transfer bitts are projected by the cam 28 whose operation with that of cam 34 has been so arranged during the previous course that the short butt group preceeding the long butt group, and odd needles only take yarn. Thus a loop is formed between alternate needles, extending across and held by the transfer butts. The first loop of the held course is at substantially the same circumferential location as the first stitch of the stocking. On the revolution following the welt courses, knitted on all needles, the even needles are raised before the knitting station so that they can take the held loops. On this revolution the bolt cams are inserted while the short butts pass so that projection of the long butt transfer bitts to transfer loops occurs half way through the revolution. Commencement of the transfer is thereby spaced circumferentially from the commencement of the stocking, viz at the opposite side of the cylinder from needle 1.

Patent ES-348699-A1 (ES)
Title: Process for recovering acrolein by quenching,absorption and plural distillation
IPC: C07C45/82
Filed: 1967-12-27
Abstract: Acrolein, in the form of an aqueous solution, is recovered from a gaseous reaction mixture obtained by gas phase catalytic oxidation of propylene by quenching, directly or indirectly, said reaction mixture down to a temperature of 30-80 C. to separate a condensate from the uncondensed vapour and then absorbing said uncondensed vapour into water at a temperature of 0-30 C. (after or while cooling the vapour to a temperature of 0-30 C.) to obtain an aqueous solution containing predominantly acrolein. In practice, the indirect quenching is effected by the use of cooling water or another suitable cooling medium and the direct quenching is effected by the use of the condensate itself after cooling. The condensate separated from the gaseous reaction mixture in the quenching step may either be discarded or subjected to distillation to recover the acrolein therefrom. The subsequent absorption stage is carried out after cooling the vapour indirectly either before or after the vapour enters the absorption column or directly by the use of the water for absorption, which is itself cooled so that the stated temperature range will be reached when the absorption of vapour occurs. The aqueous solution of acrolein is subsequently concentrated and purified by subjecting it to distillation, preferably under a pressure of 70 mm. Hg and at a temperature of - 1-53 C., and preferably by blowing steam into the distillate. Improved yields of pure acrolein are achieved if a small amount of polymerization inhibitor is added during the steam distillation.

Title: Integrated circuit for electronic timepieces
IPC: H01L49/02
Filed: 1972-12-27
Abstract: An integrated electronic circuit operating in conjunction with an electromagnetic transducer for sustaining a tuning fork in vibration, the fork serving as a frequency standard for a timepiece. The electronic circuit includes a super-gain transistor whose output is connected through an external power source to the drive coil of the transducer associated with the tuning fork to produce current pulses for actuating the fork. The voltage induced in the phase-sensing coil of the transducer is applied to the input of the transistor through a coupling capacitor, a resistor providing base current for the transistor, whereby regeneration occurs to sustain oscillation at a rate determined by the resonance frequency of the fork. The capacitor has a value in the picofarad range, this small value being offset by a large resistor value in excess of 100 megohms, the resultant decrease in base current being compensated for by an increase in current gain effected by the super-gain transistor. The capacitor, the resistor and the transistor are fabricated as a monolithic device, making possible a miniature timepiece construction.
