Title: Methods of producing webs, strips or ribbons of textile pile material
IPC: D03D47/40
Filed: 1970-01-16
Abstract: 1,263,874. Finishing edges of non-metallic sheet material. FERDINAND VAN DAMME & ZONEN. 16 Jan., 1970 [28 Feb., 1969; 13 May, 1969], No. 2266/70. Heading B5K. [Also in Division D1] Webs, strips or ribbons of textile pile material are produced from wider webs, strips or ribbons with at least the pile at least partially comprising thermoplastic material, by heating the starting web, strip or ribbon along those portions which are to form the longitudinal marginal edges of the web, strip or ribbon to the softening temperature of the pile to soften only the pile, pressing the heated portions to cause the pile in a plastic condition to be driven into the interstices of the pile carrier material, and cutting along these portions to form webs, strips or ribbons without the physical state of the warp and weft threads of the pile carrier material being substantially modified. Prior to heating, the pile may be reduced to a length such that the plastic mass of pile produced by the heating is not substantially greater than the volume available to receive this mass in the interstices of the pile carrier material. The reduction in length is effected by cutting, shearing, grinding, milling, abrading or trimming. The heating and pressing operations may at least partially overlap in time and they may be performed simultaneously. The cutting operation may be carried out simultaneously with the heating and pressing operations.

Title: Improvements in sighting correction apparatus for guns mounted on aircraft
IPC: F41G5/18
Filed: 1937-01-27
Abstract: 483,767. Sights for aircraft guns. ALKAN, R. Jan. 27, 1937, No. 2383. Convention date, Feb. 7, 1936. [Class 92 (ii)] Means for automatically correcting the angle between the sight and gun to suit the speed of the aircraft and to take account of the aiming movements of the gun in azimuth and elevation comprises a lens 19, crosswires 21, and reflecting surfaces 18, 20 forming a collimator for viewing the target and an image of the crosswires superposed thereon. The casing of the collimator is fixed to the gun, the crosswire support 17 being universally jointed to the casing at 12, 13 so as to be movable horizontally and vertically by mechanism controlled by flexible connections with the gun support 28. This support is pivoted horizontally at 28a in a. frame 27 turning in azimuth about an axle 25 carried by the usual U-shaped elevating arm 25a of an aircraft ring mounting 39. The mechanism controlling the crosswire support 17 comprises a crank-shaft 14 carrying at one end a crank pin engaging a slide 16 on the support 17 and at the other end a crank pin 5 engaging a pivoted inclined plane 4 which causes the crank shaft to slide in the hub of its driving worm wheel 7. This wheel is rotated to conform with azimuthal rotations of the turret ring 39 by a flexible shaft 36 connected to a worm 11. Azimuthal rotations of the frame 27 apply a correcting axial movement to the worm through cam 26. roller 31, rocker 32, cable 10 and spring controlled lever 9. Elevational movements of the arm 25a are conveyed by a cable 33 to a pulley 30 on the axle 28a which pulley is also connected by a cable 1 to a pulley 2 on a shaft carrying a cam 3 engaging the inclined plane 4. Vertical movements depending on gun elevation are thus conveyed to the crosswire support 17 as the crank-shaft 14 slides and revolves. To adjust the apparatus for varying speeds of aircraft the casing carrying the crank-shaft is adjustable relatively to the collimator casing which causes the block 16 to slide in the support 17. The pins connecting the collimator casing to the gun pass through resilient bushes to eliminate the effects of shock. The crosswires are preferably illuminated by a lamp 23 fitted with a reflector 24 and diffusion screen 22.

Patent GB-753461-A (GB)
Title: Improvements in cellulose ester textile materials
Inventor: FINLAYSON DONALD
IPC: D01F2/28
Filed: 1953-01-29
Abstract: Textile materials are made of or contain filaments of a simple or mixed cellulose ester of propionic or butyric acid which has a propionyl or butyryl value (reckoned as propionic or butyric acid) of at least 25 per cent and contains less than 0.5 free hydroxyl groups for each anhydroglucose unit, and which also has a high degree of crystallinity as shown by its X-ray diagram.  Filaments obtained directly by dry, wet, or melt spinning cellulose esters of the specified composition have a relatively low degree of crystallinity, as shown by diffuse rings in their X-ray diagrams, but they may be converted into products of high degree of crystallinity, as shown by relatively sharp circles or arcs in their X-ray diagrams, by a heat treatment below the thermal softening point or treatment with mild swelling agents, under such conditions that the filaments do not shrink by more than 5 per cent of their length.  The textile materials may be subjected to dry heat at 110-175 DEG  C. in the case of cellulose tripropionate, or 100-150 DEG  C. in the case of cellulose tributyrate.  The time of treatment may range from 5 to 15 minutes at 100-120 DEG  C. to as many seconds as the softening temperature of the cellulose ester is approached.  Lower temperatures, e.g. down to 80 DEG  C., may be used if the heating is carried out in the presence of water or wet steam, and temperatures below 60 DEG  C. may be used if the heating is carried out in the presence of an organic liquid which is a mild swelling agent for the cellulose ester, or in the presence of the vapour of a solvent or swelling agent, e.g. ethylene chloride, acetone, ethyl acetate, or benzene vapour.  Treatment with such vapours may be carried out at room temperatures, i.e. 15-25 DEG  C. Materials of mixed acetate propionates or acetate butyrates of cellulose may be subjected to the treatment.  A textile material of a partially esterified cellulose, particularly of cellulose acetate, may be subjected to propionylation or butyrylation to obtain a material of the desired composition and the material may then be subjected to treatment to impart a high degree of crystallinity to the cellulose ester.  The treatment may be applied to individual batches of material, e.g. lengths of fabric or hanks of yarn, or continuously as to a running fabric or yarn. Yarns may be treated on thread-storage, threadadvancing reels or like devices.  Heat may be applied to the material by means of a fluid heat-transfer medium, e.g. hot air, dry or wet steam, or hot water under pressure, or by means of heated plates or rollers or infra-red heating devices.  The treated products are resistant to shrinkage at elevated temperatures, e.g. 180-200 DEG  C. Specifications 443,707, 443,773, 719,853, 719,860, 721,674, 726,900, 731,930 and 748,772 are referred to.  The Provisional Specification also refers to Specifications 448,816 and 448,817.
