Title: Improvements in and relating to elastic textile fabrics and yarns
Inventor: PARKER CHARLES SCHWABE
IPC: D02G1/00
Filed: 1953-09-12
Abstract: 777,449. Finishing fabrics. BLEACHERS ASSOCIATION, Ltd., and BRADFORD DYERS' ASSOCIATION, Ltd. Sept. 9, 1954 [Sept. 12, 1953], No. 25251/53. Class 42 (1). [Also in Group IX] Thermoplastic textile fabric is rendered elastic by mechanically shrinking it in a compressive shrinking machine to a predetermined length shorter than its normal length and setting the fibres in their shrunk condition by heating and cooling. Temperatures employed in the setting treatment are from 250‹ to 400‹ F. The shrinking is preferably effected on a machine as described in Specification 529,579 or in a machine employing a contracting surface as described in Specification 402,087, and imparts a fine crimp to the fibres. By " thermoplastic textile fabric " is meant a woven or knitted fabric which contains a substantial proportion of thermoplastic fibres. Such fibres may be made of polyamides, polyaminolactams, polyesters, polyacrylonitrile, polyvinyl or polyvinylidene esters, or co-polymers thereof. The degree of elasticity imparted may be controlled by varying the amount of shrinkage and by adjusting the temperature of the setting treatment. Shrinking and heat-treatment are preferably carried out simultaneously, but may be effected successively. In an example, a fabric of " Terylene " (Registered Trade Mark) was shrunk by 38 per cent at 350‹ F.; the fabric then had an extensibility under load of 25 per cent with 100 per cent elastic recovery. When used for electrical insulation, the elastic fabric is given one or more coatings of a, linseed oil base varnish which is baked on, e.g. by passing the fabric through a bath of the varnish and guiding it up and down a tower through which hot air circulates. Specifications 359,759, 371,976, 372,803 and 400,950 also are referred to.

Title: Improvements in or relating to a process for the purification of hydrocarbon oils having an initial boiling temperature higher than 100íÒ c
IPC: C10G19/06
Filed: 1957-08-12
Abstract: In a process for purifying hydrocarbon oils which have a higher initial boiling point than 100 DEG  C and which contain naphthenic acids the oil is treated, in order, with : (i) an aqueous solution containing both a free alkali metal hydroxide and the salts thereof with organic acids having dissociation constants between 10-4 and 10-11; (ii) sulphuric acid; and (iii) an aqueous basic solution having a pH of not more than 8.5. Salt-forming organic acids mentioned are phenol and alkyl phenols (and the thiophenols); fatty acids, e.g. isobutyric; and naphthenic acids of lower molecular weight than those to be removed from the hydrocarbon oil.  The preferred aqueous solution is the spent caustic solution obtained from the caustic treatment of a lower-boiling hydrocarbon, e.g. cracked gasoline through the salts may also be added as such to fresh alkali metal hydroxide solution.  The salt content of the solution preferably exceeds 15 per cent wt.  The sulphuric acid treatment is preferably conducted by recycling the acid phase with 0.2 to 3 per cent wt. of spent acid being replaced by fresh acid every cycle.  The volume ratio of acid phase to oil is generally between 1 : 10 and 1 : 1.  The aqueous basic solution is generally a solution of a salt of a weak acid and strong base, e.g. sodium carbonate or acetate and it may also contain an alcohol, e.g. ethanol.  Preferably 10 to 50 parts by volume of a 1-5 wt. per cent salt solution is used per 100 parts of oils.  The treated oil may be water-washed and dried in a salt filter.  The process is particularly applicable to oils boiling between 200 DEG  and 400 DEG  C. and is generally carried out at between 20 DEG  and 80 DEG  C.

Title: Machine for stretching webs of film and the like longitudinally

Abstract: 1,013,980. Stretching films. MARSHALL & WILLIAMS CORPORATION. June 22, 1964 [April 28, 1964], No. 25679/64. Heading B5B. In a machine for stretching webs of film longitudinally a web W (Fig. 5) is drawn from a supply source (not shown), passes over freely rotatable guide rollers 142 and 148 and then in succession over driven feed rolls 41 and 40 which are provided with associated pinch rollers 154 and 170 which may be urged into contact with the feed rolls or spaced therefrom (for threading up) by means of hydraulic cylinders 162 and 182 respectively. The web W then spans the stretching zone " Z," passes over in succession the driven draw rolls 38 and 37 and leaves the machine after passing over the freely rotatable guide roll 97. Pinch roll 98 can be urged against draw roll 38 by means of the hydraulic cylinder 102. The distance between the feed roll 40 and the draw roll 38 (and hence the length of the unsupported portion of the film web at any moment being stretched can be adjusted by pivoting the arms 30 (on which the draw rolls 37 and 38 are rotatably mounted) about shaft 44 by means of the double acting air cylinder 50. The extent to which the arms 30 are pivoted is controlled by rotating cross-shaft 214 which through bevel gears 234 rotates a shaft within tubes 241 and thereby positions a nut in selected position within each tube 241. The nuts function as stops for rods 246 which are slidable within tubes 241 and are attached to the arms 30 by yokes 248 and cross-pin 50. The draw rolls 37 and 38 are driven at higher peripheral speeds than the feed rolls 40 and 41. The temperatures of all four rolls may be controlled by circulating a heat-exchange fluid through them. The film web in leaving the roll 40 may be heated by means of the radiant heater 290 the distance of which from the film is adjustable.

A carton is formed from a blank treated with a sealing medium by the steps of locating it over a mould, urging it down therein to form vertical side and end walls, sealing these walls together in the vertical position by simultaneously applying heat and pressure, and ejecting the completed carton. The blank is located over the mould 11 with the wings on its side walls upstanding and is then forced down by a mandrel 13 operated by rams 12 to fold up the walls, the wings lying against the inner surface of the adjacent end walls; while the blank is thus held by the mandrel 13 and spring-loaded plates 10a, the end walls and the wings, which are impregnated with a latex sealing medium, are sealed together by pressure elements 23 having heaters 24. Ball-and-socket joints 25 allow automatic setting of the pressure elements 23; the operating sequence is automatic and entry of the next blank into the mould 11 ejects the carton on to a shoot. In a modification glue is applied to the top blank of a stack, the blank being then lifted by suckers and moved into position above the mould.
