Filed: 1972-04-20
Abstract: 1394604 Air laid web former E I DU PONT DE NEMOURS & CO 20 April 1972 [20 April 1971] 18346/72 Heading DIN An apparatus for forming textile webs on a moving screen 26 has a duct through which a closely controlled low turbulence air flow passes and into which a uniform layer of fibres 22 is projected through a slit at at least 3000 ft/min; the fibres remaining as a distinct layer within the thickness of the air stream and being conveyed as such to the moving screen 26; the fibres being injected by a toothed roll 8 in co-operation with a curved plate 10 at a clearance of less than 0.125 inches from the roll teeth. The air flow is maintained within close velocity limits and with low turbulence across the entire duct depth and width with the exception of boundary layer regions. Velocity limits and turbulence levels are given. The air flow is stabilised by a honeycomb 40 and screens 38, 42 and is conducted to the working section by a nozzle 18 suitable forms of which are disclosed. The boundary layer through which the fibre stream passes may be controlled by e.g. a suction slot (44) Fig 2 (not shown), or an obstruction (62), Fig 3 (not shown).The fibre stream may be induced to thicken by a solid obstruction across the duct or a similarly positioned perforated bar, Figs 4 and 6 (not shown). The air flow may recirculate as shown, or the system may be open ended. The duct may be curved and may flare or taper and the collecting screen may be inclined. Suitable ranges of dimensions and speeds of most parts of the apparatus are given together with examples of data from test runs.

Title: Process for the preparation of a biaxially oriented polyester  film
IPC: B29C55/28
Filed: 1973-04-17
Abstract: 1430291 Stretching polyethylene terephthalate films TEIJIN Ltd 17 April 1973 18372/73 Heading B5B Biaxially stretched polyethylene terephthalate films are produced by a two-stage drawing process. In the first step the film is drawn to 3À5 to 5À0 times its original dimension at a temperature such that the refractive index n sd  of the film after this step is less than 1À560. In the second step the film is drawn in the transverse direction to 3À0 to 4À0 times the original dimensions at a temperature of 50- 150‹ C. The first step may be preceded by a predrawing in the same direction to 1À2 to 3À0 times the original dimension and a temperature between the second order transition temperature and 120‹ C. The second step may optionally be performed in two stages, the first at a temperature of 50-95‹ C. at a draw ratio of at least 1À1 but less than 95% of the total draw ratio of this stage, the second completing the drawing and being performed at a temperature from 70- 150‹ C. and greater than or equal to the temperature of the first stage of this second step. Preferably the first drawing step is performed in the machine direction and the second in the transverse direction. The film may optionally be heat-set. The film may contain no more bifunctional acid components other than terephthalic acid, and diol components other than ethylene glycol, than a total of 15 mol per cent.

Abstract: 1,081,237. Control of two A.C. motors. INSTITUT FUR FORDERTECHNIK LEIPZIG. April 28, 1966, No. 18725/66. Heading H2J. In sorting apparatus, a cabin is driven horizontally by squirrel cage motor m1 with reversing relays c1, c2, and control switch b1. The drive for vertical travel comprises squirrel cage motor m2 associated with reversing relays c3, c4, pole-changing relays c5, c6 and control switch b2.

Title: Improvements in or relating to shock absorbing struts
IPC: B64C25/60
Filed: 1929-06-18
Abstract: 332,029. White, A. E., (Cleveland Pneumatic Tool Co.). June 18, 1929. Fluid - friction vibration - dampers; pneumatic springs. - Telescopic struts or shockabsorbers applicable to the landing gear of aircraft and to vehicles are adapted to resist compressive forces by pneumatic means and are also adapted to prevent sudden extension by liquid friction and by friction between gland packing and the cylinder. A piston 14 on the end of a piston rod 16 of large diameter works in a cylinder 11 containing both air under pressure and oil. The piston rod 16 passes through a stuffing box in which packing 34 is retained in position between a screwed gland 35 and a pressure ring 32 which normally abuts against a shoulder on the cylinder 11. Leakage of the liquid from one side of the piston to the other is controlled by means of a loose annular ring 24 movable lengthwise of the cylinder between the underside of the piston and a shoulder on the end of a piston rod 16. The ring is formed with three holes 26 which are connected by a circular recess 30 in the upper side of the ring. Three gauged holes 28 in the piston 14 communicate with a circular recess 29 on the underside of the piston, the recesses 29 and 30 being of the same diameter so that liquid is always free to flow through the gauged openings 28 upwards or downwards. The piston is also provided with three holes 31 of larger diameter which are closed by the ring 24 when it is m its raised position. Compressive forces applied to the apparatus are resisted by the internal air pressure. Rapid extension of the apparatus under the action of the internal pressure is resisted by the restricted flow of liquid through the small gauged orifices 28, the loose ring 24 then being in its uppermost position. The pressure of the liquid under the piston forces the packing-retaining ring 32 downwards so as to expand the packing 34 radially and resist movement of the piston rod and piston in the cylinder.

A bearing for a rotatable shaft 11 comprises blocks 12, 13, the former being the journal load-carrying portion and having a soft metal lining 14, and the latter having thrust loadcarrying surfaces 15a. The block 13 has a semi-circular bore of greater radius than that of the shaft, thus forming an oil reservoir 18 which is supplied with oil through passages 19 in the block 12 from troughs 21 in the block. Oil may be supplied to the troughs during rotation of the shaft by an oil ring or paddle on the shaft dipping into a main oil reservoir. The reservoir 18 is sealed by half-ring P.T.F.E. seals 23 urged by zig-zag springs 24, 25 into engagement with recesses in the block 13, and the shaft. On rotation of the shaft, oil is supplied to the load-carrying portions of the bearing almost immediately, from the reservoir 18. The lower-bearing block 13 may take part of the journal load by providing a lining 31, and the seals may be spring-urged against collars on the shaft, or the seal at one end of the shaft may be replaced by a cover.

Filed: 1963-05-15
Abstract: A coarse gauge fully fashioned stocking machine is converted to an outerwear machine by the modification of predetermined cams to alter the stitch quality and altering the slurcock to ensure that each time the sinker is fully advanced by the traverse of the slurock the yarn kink is fully formed about a needle before the slurcock starts to advance the next following sinker to kink the yarn about the next following needle.  The quality control cam is modified to increase the loop size and the needle bar raising cam is altered to ensure that the beards are pressed clear of the fabric loops.  The alteration of the needle bar presser cam gives greater pressure to the needle bar and prevents the fabric causing a miss press and modification of the knock over cam allows for double fabric thickness during the formation of a turned welt.
