Patent ES-318225-A1 (ES)
Title: Method of bulking textile yarns
IPC: D02G1/18
Filed: 1965-10-07
Abstract: Bulk is imparted to continuous filament yarn by differential shrinkage between two or more constituent interlaced bundles of at least two different types of filaments, and the effect may be enhanced by subsequent falsetwist crimping, texturising within a turbulent fluid zone as described in Specification 732929, and/or forming crunodal loops in preselected filaments. Each bundle has a twist of 0-1 turns per inch which is not increased by interlacing (effected, under controlled tension and without formation of loops) by air jets. The shrinkable (10-20%) component (15-75% by weight) may be stretched, but unstabilised, filaments of nylon 6 or 66, copolymers of acrylonitrile and vinylidene chloride, acrylics, polyesters and polyolefins: an unshrinkable component may be stabilised forms of such filaments or cellulose acetate or triacetate, viscose rayon including polynosics. In a continuous process, one or both forms of filament may be freshly spun or drawn from supply spools, stretched (if necessary) between godets, combined (in passing over one godet) passed through an air jet interlacer, and collected on bobbin(s) by a ring and traveller. The differential bulk effect is developed by subjecting the running yarn or wound hanks to heat and/or moisture e.g. in a liquid bath or steam chamber: alternatively, bulk may be developed after weaving or knitting the yarn into fabric the final form of which may exhibit crepe weave or marl appearance. The bundles may be similar or different as regards the nature of the materials, denier, the number and the cross-sectional form of constituent filaments, the direction of residual twists, lustre or dye receptivity, and the degree of interlacing may vary along their length: resultant esthetic effects may occur in the yarn and/or fabric. Interlaced yarns, perhaps of different construction and finish may be used as warp and/or weft in fabrics.

IPC: B65B63/02
Filed: 1965-11-30
Abstract: Segregation according to size etc., of particles of a metal-containing pulverulent material in an air-tight bag is prevented by reducing the air-pressure within the bag to 'below atmospheric pressure by at least 0À2 kg./cm.2 before sealing.

Abstract: In a self-cleaning gas oven, food soils are cleaned from the walls of the cooking compartment 13 by heating the outer surface of these walls to a temperature between 750-950 F. with flue gases. A firebox 45 housing a burner unit 47 supplies flue gases during heat cleaning to a heating channel 74 surrounding the compartment 13 through apertures 75. Baffles 86, 87, 88, 89 direct the flow of flue gases which finally leave the channel 74 through an opening 79. A damper 70 is provided to close apertures 43 through which flue gases enter the compartment 13 during normal cooking operations, and a further damper 72 closes an exhaust vent 63. The gaseous products of the heat cleaning leave the compartment through an oxidation unit 80 which comprises a perforated ceramic block coated with a catalyst, e.g. platinum. The outer oven easing 16 is cooled by a fan 91 inducing air through a channel 90. This air is mixed in the region of a baffle 78 with the exiting flue gases before being discharged through an exhaust vent 67. Additional fan units (Fig. 3) may be provided for cooling the side walls of the outer oven casing 16.
