Abstract: 1495151 Embossed films SMITH & NEPHEW RESEARCH Ltd 20 June 1975 [21 June 1974] 27636/74 Headings B5A and B5B [Also in Division B2] A polymer film has one surface embossed with a plurality of primary, parallel ribs and grooves and the other surface embossed with a plurality of more closely spaced secondary, parallel ribs and grooves which are at an angle of at least 30 degrees to the primary grooves. The combined depths of the grooves may be such that only a thin membrane is left at the intersections of the primary and secondary grooves or the depth may equal the thickness of the film which is thus perforated. The film must be predominantly uniaxially stretched in a direction perpendicular to that of the primary ribs and grooves. Preferably the primary grooves are longitudinal and the secondary ones at right angles to them. The film may optionally be stretched in the direction of the primary grooves, but only to an extent less than that in the perpendicular direction. The film may be made by embossing a melt between two chilled embossing rollers. The preferred material is high density polyethylene, either alone or mixed with polystyrene. The film may be split into tapes by tearing in the direction of either of the grooves. Corona discharge may be applied to the film or the tape in order to increase the strength of the bond to an adhesive coating.

Title: Improvements in method and apparatus for forming pouches in circularly knitted fabrics
IPC: D04B35/00
Filed: 1964-07-07
Abstract: 1,026,467. Knitting. TEXTILE MACHINE WORKS. July 7, 1964 [July 12, 1963], No. 27974/64. Headings D1C and D1K. The mechanism for simultaneously adjusting the stitch cams at each of the four feeding stations of the circular machine described the Specification 946, 955 has superimposed on it further mechanism which controls the stitch cams at each station independently of the others so as to enable the quality of the fabric not only to be varied throughout the whole circumferential extent during the knitting of the leg of a stocking but also to enable the quality of that portion of the tubular fabric knitted by continuous rotary knitting and which is to form the heel of the stocking to be further varied in a graduated form so as to accentuate that portion of the fabric and render it more suitable for a heel pocket. To this end the shaft 25 at each station controlling the movement of the needle cams has loosely mounted on its end a member 26 having a portion 27 against which screws 30 secured in a lever 31 attached to the shaft 25 are adapted to bear. A spring 32 maintains the screws 30 and portion 27 in contact such that as member 26 is pivoted by a lug 36 on a ring member 37 the screws 30 remain in contact under the influence of spring 32 to cause the lever 31 to rotate and with it the shaft 25 thereby adjusting the needle cams. The cams at each station are simultaneously operated in a similar manner when knitting the leg of a stocking to gradually reduce the tube diameter. At each station there is attached to one arm 60 of the lever 31 a cable 61, the cables from the four knitting stations being secured at their other ends to a corresponding one of a bank of levers 65. One arm of each lever is secured to a cable 61 and the other carries a follower 77 adapted to engage a cam 81 there being a cam 81 for each lever 65 and the cams being concentrically mounted but with their lobes 81 out of phase. The cams 81 are rotatably mounted on a pivoted arm 86 and adapted to be pivoted to bring the cams 81 gradually into and out of engagement with the levers 65 by a cam 96 mounted on the arm 86 and having a profile which engages a fixed roller 100. The cams 81 are driven by a chain and sprocket drive from a shaft 87 so as to rotate continuously. The driving shaft 87 carries a collar 135 having rollers which engage a lever 126 causing it to be pivoted and through a link 127 actuating a pawl and ratchet mechanism driving the cam 96. Consequently as cam 96 is rotated the cams 81 are brought closer to the levers 65 causing them to pull on the cables 61. The levers 65 operating in turn and to a varying extent as determined by the cam 96, the cables likewise operate the levers 31 to a varying extent each course causing the needle cams to be adjusted over part of the courses to effect additional variation in stitch length to create a heel pouch in the tubular fabric.

Title: Improvements in apparatus for measuring the hardness of metals
IPC: G01N3/52
Filed: 1927-10-22
Abstract: 280,182. Etablissements Vallaroche. Nov. 2, 1926, [Convention date]. Testing hardness of metals.- Relates to apparatus of the type in which a striker is freely dropped on to the specimen and automatically held at the maximum height of rebound by a ring of balls and consists in providing a striker, the upper end of which is fitted with a screwed oap and the lower end with a screwed ring for securing a hard ball, both ends being thus adjustable. A ball 2 is secured by a screwed cap 3 to the lower end of a rod or striker 1 guided in a tube 5 at the lower and upper ends of which are screwed rings 6, 7 respectively. The upper part of the tube 5 is formed of a ring 8 with a tapered bore 8'. An annular member 10 surrounding the rod and undercut at the upper end to provide a resilient top is slotted to receive balls 9 which are normally jammed between the tapered surface and the rod thus holding the latter. In use, the striker is lifted until the cap 3 engages and raises the member 10 which is held by a friction ring 11 so that the balls do not jam the rod. The rod is dropped and during the impact the screwed cap 12 at the upper end of the rod engages the member 10 and pushes it down sufficiently so that the balls hold the rod at the maximum height of rebound. The rod may be graduated in Brinell hardness numbers. Holes 14 are provided to prevent air-cushioning. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the graduations are made along a slot lengthwise of the guide tube, which may be. surrounded by a second rotatable slotted tube, and also a trigger release for the striker. This subject-matter does not appear in the Specification as accepted.

Filed: 1950-11-17
Abstract: 692,729. Machines for lacing shoe-uppers. BRITISH UNITED SHOE MACHINERY CO., Ltd., and RIVINGTON, A. A. Nov. 16, 1951 [Nov. 17, 1950], No. 28111/50. Class 43. In a machine for lacing shoe uppers, comprising a row of parallel needles, such as 1-4, Fig. 2, and co-operating means to form a series of loops in a lacing cord, for example in the manner disclosed in Specification 7013/06, [Class 112], the needles are each secured within an axially rotatable member 5, each endmost needle 1 and 4 being located eccentrically in its mounting member, as shown, and means are provided for imparting a partial rotation to each needle mounting member of the row, so that in one position of adjustment the needles 1-4 lie in a common plane and in another they lie in a curved row, as in Fig. 3, thereby enabling the machine to be used upon shoe upper parts provided with eyelet holes lying in curved or irregularly shaped lines. With the needles arranged in a common plane, as shown in Fig. 2, below a line of looper fingers (not shown), a cord-feeding needle lays a length of thread across them, the looper fingers are moved relatively inward, and the needle-mounting members 5 are rotated axially through 90 degrees. The last mentioned action brings the legs of the loop into a position to permit the subsequent passage of the cord feeding needle between them, and at the same time the eccentricity of the mounting of the needles 1 and 4 causes those needles to lie in a lower plane than the needles 2, 3. A workpiece, indicated in broken lines in Fig. 3, and with eyelets A arranged ina curve, corresponding to the positions of the ends of the needles 1-4, is then placed on the needles and over the loops of thread thereon, whereupon a rigid member 7, Fig. 5 (not shown), is moved downwardly and rearwardly by operation of a treadle to position the shoe upper parts correctly upon the needles. This movement of the member 7 also brings it intoengagement with the front ends of the two endmost needles 1 and 4 which are thereby bent upwardly and brought into alignment with the inner needles 2 and 3. With the needles thus arranged the cord-feeding needle is passed across the needles and through the loops formed from the thread laid across them previously. The deflection of the front ends of the eccentrically mounted end needles 1 and 4 is facilitated by making them of reduced thickness over a region 9 adjacent to their mounting members 5.
