Title: Fabrics made from bulked yarns
Inventor: SCHULZ FRANCIS
IPC: D02G1/00
Filed: 1959-11-16
Abstract: 922,405. Spinning and finishing yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. Feb. 15, 1961 [Nov. 16, 1959], No. 38748/59. Class 120 (3). Bulked yarn comprises continuous filaments of synthetic thermoplastic polymers e.g. polyesters and copolyesters, or polyolefines such as isotactic polypropylene, having a deliberately reduced strength compared with commercially available bulked yarn i.e. the tenacity of individual filaments, when measured at intervals of not more than three quarters of an inch, is uniformly or non-uniformly reduced from at least 4 grams per denier to 1-3.5 grams per denier. The yarn may be a non-torque singles, false-twist, stuffer-box, hot wire or gear crimped, with crimp elongation less than 15% and shrinkage per unit length in hot water or steam of not more than 10%. The initial filaments may be spun e.g. with denier variation along their length, or mechanically and/or chemically treated to produce the reduced tenacity, or a bulked yarn may be so treated. The finished yarn is stated to resist " snagging " and " pilling." Specifications 777,625, 808,213, 881,729, 921,583 and 922,406 are referred to.

Title: Apparatus for fan-folding web material
IPC: B41J15/04
Filed: 1973-08-16
Abstract: 1403475 Folding sheet material INTERNATIONAL BUSINESS MACHINES CORP 16 Aug 1973 [5 Sept 1972] 38795/73 Heading B8R In a zigzag folder, a web 6 formed with spaced lateral weakening lines to define sheets 8 is introduced by rollers 9, 11 to a curved guide 24 which brings it into contact with chains 12 moving slightly faster than the web feed, the lower run of the chains sagging towards a stacking platform 18, the sheets being stacked with alternate fold lines abutting guide means 40, 22. The guide means 40 is adjustable by rotating a shaft 32 between a position adjacent the shaft and a position 20<SP>1</SP>, according to the distance between the weakening lines, that part of the lower run of the chains to the right of the right-hand guide means being supported on a ramp 42. In the case of light-weight paper, belts 50 having projections 52 are moved into a position to engage and assist the descent of the fold lines to be stacked against the guide means 22. As the stack increases in height, the table 18 is lowered by a lead screw 62 rotated by a motor in response to a signal generated when the stack prevents a horizontal beam of light from reaching a photo-cell 60. In another form, Fig. 1 (not shown), the right-hand guide is fixed in its rightmost position, and the belts 50 and ramp 42 are dispensed with. The apparatus can be used to stack separate sheets.

Title: Improvements in and relating to non-woven fabrics
IPC: D04H1/64
Filed: 1965-09-10
Abstract: 1,125,955. Non-woven fabrics; shrinking fabrics. WEST POINT MFG. CO. 10 Sept., 1965 [10 Sept., 1964], No. 38830/65. Headings D1R and D1S. Non-woven fabrics are impregnated with a heat-curable binder of natural rubber or synthetic resin, dried, subjected to mechanical compressive shrinkage before the binder is fully cured, and heated to cure the binder whilst held in the compressed state. If the binder is thermoplastic before curing, it will soften during heating to adjust to the rearrangement of fibres during the shrinkage. The fibres of the fabric may be of polyethylene, polypropylene, nylon-6, nylon-66, polyethylene terephthalate, wool, cotton, acrylics, modacrylics, polyurethane, rayon or acetate rayon, and may be formed into a web by air-blowing, carding or cross-laying. Binders referred to are self-curing acrylic copolymer latices, "Hycar" (Trade Mark), and natural rubber The binder may also contain marble dust, zinc oxide or finely divided clay to reduce tackiness. The binder may be wholly uncured or partly cured before shrinking, or a first increment of binder may be applied and cured and a second increment applied but not cured before shrinking. The shrinking may be done on a two-drum shrinking machine.

Title: Device for displaying characters
IPC: G09G5/22
Filed: 1975-09-23
Abstract: 1512688 Cathode-ray tube circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 Sept 1975 [26 Sept 1974] 38937/75 Heading H4T A new character can be inserted at a desired position in a selected one of a number of rows of characters displayed on a television display tube by modifying the shift rate of signals representing that row of characters in a shift register. The system includes a one-row shift register store (89, Fig. 4, not shown) and a buffer store (86) which may also be a shift register, the total capacity of the two stores being sufficient to store the character signals of all the rows to be displayed. During display switching units (85, 88) cause both stores to recirculate their contents, the row store circulating once for each scan line of the display. The output of the row store also passes to a character generator which provides bright-up pulses to produce the characters in dot matrix form on the c.r.t. When the number of scan lines sufficient to display the present row has been counted a certain number of blank scan lines occur to provide the spacing between this row and the next. During blank lines switching units (85, 88) connect the output of the row store to the input of the buffer store and the output of the buffer store to the row store, so that the row just displayed is returned to the buffer store and replaced by the next row to be displayed. A character to be added to a row is presented at an input (98), e.g. from a keyboard. In addition a cursor signal is generated, the cursor signal defining the horizontal and vertical co-ordinates of the position at which the character is to be inserted. The cursor is displayed on the c.r.t., e.g. by inverting the video signal at that position. During the transfer of the relevant row from the row store to the buffer store, i.e. during blank scan lines, comparators responsive to the cursor signal and to corresponding system clock pulses cause a shift pulse to be withheld from the row store. This occurs immediately after the portion of the row preceding the insertion point has been transferred and consequently the remainder of the row lags by one character position relative to the first portion. The blank position so created is filled by the character received at the input (98) so that the row just displayed and now in the buffer store (86) now contains the new character. Several characters may be inserted in a single cycle by suppressing the relevant number of pulses. A character may be deleted in an analogous manner, the row store receiving an extra shift pulse at the relevant instant so that the character is read out of the row store before the buffer store can receive it causing it to be "lost" without causing a blank in the row.

Abstract: 907,563. Rolling. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 16, 1958 [Dec. 19, 1957], No. 40537/58. Class 83 (4). In forming two or more axial grooves 8, Fig. 2, of a superfinished steel shaft 26 of not greater than 6 mm. diameter, one end of the shaft 26 is positioned against a stationary support and the edges of two or more steel wheels 16 are pressed into the shaft and then moved longitudinally along the shaft to form the grooves. Guides 11 mounted on a base 10 and connected together at the top by a plate 13, each carry a member 14 having rollers 15 which are pressed against the inner surface of the guide by springs 18. The members 14 are moved vertically along the guides 11 by a pressure plate 23 having depending rods 22 each rod being attached to a cage 21 surrounding each member 14. Each of the wheels 16 is mounted in one of the members 14 and the wheels guide the shaft 26 into position in a supporting cup 27 after it had been entered through a tube 24 and a hole 25 in the plate 13. The pressure plate 23 is then depressed to move the wheel-carrying members 14 downwards until the rollers 15 engage a projection 12 on each guide 11, the wheels 16 then being forced, against the action of the spring 18, into the shaft 26 to form grooves 8. On further downward movement of the members 14 the wheels 16 retract and the lower side of one cage 21 depresses a bell-crank lever 33 so moving a spring- pressed base-plate 28 as to register in aperture 31 therein with a hole 32 in the base 10, allowing the shaft 26 to fall away freely. The baseplate 28 may alternatively be moved by magnetic means. The grooves formed in the shaft may be continuous. In a modification camoperated wheel-carrying members may be stationary while the shaft moves longitudinally.
