Title: Bituminous composition
IPC: C08L95/00
Filed: 1972-03-27
Abstract: 1327535 Bituminous composition BRITISH PETROLEUM CO Ltd 27 March 1972 [31 March 1971] 14241/72 Addition to 1304238 Headings C3N and C3P A process for the production of a bituminous composition comprises blowing at 180-260 C. with a gas containing elemental oxygen, a mixture of 10-85% wt., based on the total mixture, of a bituminous substance, 5-25% wt., based on the total mixture, of a copolymer derived from ethylene, propylene and a cyclic olefin having an endocyclic bridge and at least two olefinic double bonds, and, 10-85% wt, based on the total mixture, of a flux oil for extending the copolymer, the elastomer being in the latex form when added to the bitumen. Suitable latices contain 40-60% wt. copolymer. The preferred copolymer is a copolymer of ethylene, propylene and dicyclopentadiene. The bitumen and the flux oil are preferably blended together before the copolymer latex is added. The flux oil is preferably obtained by beating vacuum distillates and de-asphalted vacuum residue with suitable solvents. Aromatic extracts obtained during the production of lubricating oils may be used. The latex may be incorporated into the bitumen/flux oil blend by stirring, or by blowing under milder conditions than those required to form the final composition, e.g. for a shorter period, at a lower temperature or with a lower rate of air throughout. Before the addition of the copolymer latex the bitumen may be heated to 150- 260 C. If necessary the mixture is then heated to 180 C. prior to blowing. The blowing is preferably carried out in two stages. The first stage may be carried out at 180-230 C. and the second at 230-260 C. The blowing time is usually in the range 8-20 hours. Sulphur may be added, suitably in an amount 0À5-4 parts by weight per 100 parts by weight of copolymer. The blown elastomerized bitumen finds application in sealing materials, pipe wrapping compounds, bitumen paints, and flexible roofing felt and may also be used as a concentrate and blended with unblown bitumen. Examples disclose mixtures comprising (1) 40% wtÀ bitumen, 50% wt. aromatic extract and 10% wt. copolymer of ethylene, propylene and dicyclopentadiene and (2) (3) 60% wt. bitumen, 30% wt. aromatic extract and 10% wt. of the same copolymer, to which varying amounts of sulphur are added. The bitumen was derived from a Tia Juana crude oil and had a penetration of 185 mm./10 at 25 C. and a softening point of 41 C.

Title: Improvements in seamless knitted hosiery and in methods and machines for making same
IPC: D04B9/12
Filed: 1945-06-08
Abstract: 622,637. Knitting. INTERWOVEN STOCKING CO. June 8, 1945, No. 14597. Convention date, June 2, 1944. [Class 74 (ii)] The leg 2 and instep 3 (including the upper part of the foot) of a seamless sock have wrap thread plated over the body thread in selected wales to form a wrap embroidery pattern; and a heel extension 12 (when present), high splice 4, heel 5, sole 6, toe band 7, and toe 8, are of terry fabric. The wrap embroidery pattern may extend into the high splice. Terry thread may be fed as an addition body thread in the leg. The instep needles have long butts, those needles which knit the portion 12 have short butts and the remainder have butts of intermediate length. The sinkers have curved fingers 39 which, when the sinkers are advanced early enough, enter under the terry yarn (fed from a point above the body yarns) and over the body yarn or yarns, so that long terry loops shall be drawn: the fingers slope upwardly so that, by a transient partial withdrawal of the sinkers in the course of their advance the terry loops are further lengthened. When the sinkers are advanced by fixed cam 48 or 49 (according to the direction of rotation) the terry yarn, if fed, is incorporated as a body thread; but selected sinkers are advanced earlier, as required, by one or more pattern-controlled hinged cams 51, 53, 54, 55, which act on suitably differentiated butts or tails. The loops are slackened in the terry portions, either by circumferential adjustment of portions 191, 192 of a composite needle-raise cam 188, or (in knitting heel and toe regions) by lowering the stitch cam block: in this latter case, the sinker cap is swung about its axis to compensate for the increased and earlier descent of the needles, so that the fingers 39 of the sinkers shall still enter between terry and body threads. The stationary part 189 of the cam may be adjustable. The terry feeder and co-operating cutter and binder are moved in and out, as required, under the control of the main pattern drum and cams. A separate terry thread feeder may be brought in for heel and toe.

Abstract: 644,028. Type - bar - making machines. SOUCHE, F. C. June 3, 1947, No. 14696. Convention date, Nov. 11, 1941. [Class 100 (iii)] An automatic line centring and shifting device for a typographical composing machine comprises, for each of the two jaws between which the line is to be cast, a rack displaced by a set of pinions driven by a connecting rod pivotally secured to a lever rocking under the action of a cam keyed to a control shaft of the machine to control the spacing of the jaws. The rack 4, Figs. 1 and 4, of the jaw 2 is driven by a pinion 9, mounted freely on a shaft 11 in a housing 8 and driven by a toothed connection with a boss 13 frictionally mounted on the shaft, which is rotated by a pinion 22 driven by a rack 24 adjustable by a stop 37 and mounted on a rod 26 vertically reciprocated by a connecting rod 29 pivoted at 30 to a lever 28 actuated by a cam 27. The rack 7 of the jaw 5 is similarly actuated by a rack 25 also mounted on the rod 26. A hand control 21 rotates a cam 20 to slide the bosses on the shafts to engage or disengage the pinions so that either or both jaws are in operation, and a member 38 can be rotated to disconnect the rod 26 from the rod 29. A spring 36 acts to return the mechanism in the casing 8 to its inoperative position. The driving connection between the lever 28 and rod 29 comprises a rod 31 with a nut 35 and a spring 32 bearing against a cylinder 33 pivoted to the rod 29 and abutting the nut 35, so that when the jaws grip the type with the desired pressure, the spring 32 is compressed to avoid further jaw movement. Both jaws move inwardly an equal amount from positions controlled by the stops 37 for centring, while one jaw rests against its stop and the other is actuated for quadding. The cam 27 may be keyed to the shaft carrying the cam controlling the first elevator of the machine.

Title: Improvements relating to input storage systems for use with electronic computers
Inventor: HARRISON GEORGE RALPH
IPC: G06F3/08
Filed: 1959-05-01
Abstract: 920,762. Record card apparatus. FERRANTI Ltd. April 22, 1960 [May 1, 1959], No. 14863/59. Class 106 (1). An input buffer for a digital computer comprises three stores and blocks of input data are each read in twice, first to one of the first two stores (selected alternately) and then to the third, the contents of the two stores being then read out to the computer, while also being compared for identity. The use of three stores enables simultaneous reading of two blocks, one into store 1 or 2 (leaving the previously-read block unchanged in 2 or 1) and the other (previous) block into 3. As shown, 1-3 are magnetic core matrix stores each of 80 columns and 12 rows for receiving the data from an 80-column punched card; the rows of the card are sensed in turn in synchronism with ¢-write signals on lines 7 (Fig. 1) from a shift register, and one of the selectors 9 opens a path through diodes 8 or 11 so that a card presented at the first reading station is read into 1 or 2 while the card previously read at this station is read into 3. Fig. 2 shows the buffer read-out arrangement; a shift register 13 operated at computer speed reads out in turn the columns of 3, and each column set of signals on lines 22 is converted by unit 25 to a series-mode signal for the computer. The shift register pulses also pass through columns of either 1 or 2 (under control of selectors 19 and 16) and read out the contents of this matrix to a unit 23, and provided that the two outputs are identical no alarm signal will be generated by 24. Thus, the operation is: (a) first card read into 1, (b) second card read into 2 and first card into 3, (c) 3 and 1 read out to computer, (d) third card read into 1 and second card read into 3 (e), 3 and 2 read out to computer, and so on.

Abstract: 420,746. Yarns. BRANDWOOD, J., 18, Saunders Street, Southport, Lancashire. May 24, 1933, No. 14941. [Class 120 (iii)] To produce by the de-twisting method a yarn having little or no twist a twisted yarn or sliver is impregnated with a liquid which is then dried off to leave a deposit upon the fibres of a plastic substance which renders the yarn plastic without impairing its flexibility, the yarn or sliver when dried being untwisted to the desired extent. The liquid employed is an emulsion in water of an oxidizing or drying oil, e.g., linseed or hempseed oil the water being dried off and the oil oxidized upon the fibres. The cheeses of yarn or silver 3 are supported upon a perforated horizontal partition 2 in a closed casing 1, an emulsion of 1À5 per cent linseed oil and 98À5 per cent water (or of a higher proportion of oil) being circulated by the pump 4 through the pipes 5, 6. After impregnation excess emulsion is removed by air circulated through the pipes 7, 8. The cheeses are then dried in a hot air chamber, e.g., at 60‹ C., the dried yarn then being untwisted. The deposited oil is removed from fabrics knitted or woven from the yarn by treatment in a hot water bath to which soda ash has been added. Alternatively continuous lengths of yarn are run through a bath of the oil emulsion, then dried and wound.
