Title: Improvements in circular knitting machines for the knitting of fabrics having terry loops on both faces thereof
Inventor: MAURICE THIBORD
IPC: D04B9/00
Filed: 1955-02-09
Abstract: 799,735. Knitting. ETABLISSEMENT DE SEREVILLE. Feb. 9, 1955 [Feb. 19, 1954], No. 3809/55. Class 74 (2). Terry loops are formed on both faces of a fabric by an arrangement in which, after terry loops have been formed in the usual manner on the inner face of the fabric, as by means of a wheel 16 over the spikes of which a terry yarn 15 is drawn, the fabric is lifted up the stems of the needles by its passage over a plate 17 and, whilst it is so lifted, a second terry yarn 20 is fed beneath it and terry loops of that yarn are sunk on the other face of the fabric by the throats of the sinkers 8, which are advanced for this purpose. The needles have, alternately, long and short butts, which co-operate with a cam 6 recessed at 21, so that alternate needles are raised high enough to take the yarn 20 below their latches for it to be cast off in the course preceding that in which it is cast off by the intervening needles which, being raised to a lesser height, take the yarn in their hooks. A second plate 23 ensures that the fabric shall be restored to its original height. The sinkers bearing the yarn 20 in their throats retain the terry loops, until after the next course ; and the grooved yarn 14 is fed under the wheel 16 and drawn over the heads 8a of these advanced sinkers.

Abstract: 1362261 Pipe couplings BRITISH STEEL CORP 27 Jan 1972 [3 Feb 1971] 3821/71 Heading F2G [Also in Division B5] To prevent crack propagation, through a sleeve-like part 1 or sleeve of a welded polythene pipe joint, from weld gap 8, the sleeve-like part or sleeve is made of polythene of ultrahigh molecular weight (0.5 to 3 million) and need not completely surround the pipe, which is of lower molecular weight. After the parts have been heated and placed together, welding pressure may be applied, by means of a surrounding collar or clamp. As an alternative to a T junction, a saddle branch-to-main connector of ultra high molecular weight polythene is welded to both pipes.

Abstract: 1,087,383. Film strip take-up. GENERAL ELECTRIC CO. Jan.28, 1966 [Feb.15, 1965], No.4000/66. Heading G2J. A drive mechanism in a cine projector for a film strip holder 11, said holder having an opening 12, in which is held a film strip 16, which is recessed from the surface 14 of the holder, comprises a centre wheel 23, two, preferably toothed, take-up wheels 20, 21 on an intermittantly driven shaft 22, back up wheels 26, 27, and optionally an alignment wheel 31 on a spring-biased axle 28. When the film holder is inserted into the drive mechanism, its leading portion 32 is engaged by centre wheel 23, which has a diameter larger than or equal to that of drive wheels 20, 21, thus relieving the driving engagement between the drive wheels and the holder until the centre wheel 23 reaches the recessed aperture of the holder so that it no longer engages the latter which is thus pushed into driving engagement with drive wheels 20, 21 by spring 29. The mechanism prevents the leading edge of the film strip holder being mangled by the drive wheels whilst it is being inserted.

The cradle may be prevented from rocking by a spring-loaded catch 37. The pillar 20 is mounted in a socket 21 which is clamped to the saddle tube 22. A spring 24 urges the pillar 20 upwardly, a stop 25 preventing its ejection from the socket 21. The pillar may be locked in one or more positions within the socket by means of a spring-urged plunger 30 engaging in holes 31 in the pillar 20.

Filed: 1924-02-18
Abstract: 211,861. Gruber, H. Feb. 22, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Testing friction. - A method of and machine for determining friction characteristics is described. A shaft 2 mounted in a bearing support carries at one end a driving pulley 3 and a.t the other a removable friction disc 4. The frame 5 also carries a slide 6 which may be displaced by a screw 7. A bar 9 is supported on the slide 6 by the hardened point 100 of a screw 10 resting in a recess in line with the axis of the shaft 2. The bar 9 is also adapted to pivot about a pin 11 also in line with the axis of the shaft 2 and engaging a groove 90. The test piece 26 which is of prismatic section and is shaped to the contour of the disc 4 is carried in a recess formed in the end of the bar 9. A bore 12 may be used to place the specimen in communication with any suitable heat-measuring instrument. The test piece is loaded by a weight 14 on a lever 15 pivoting about a knife edge 13 and connected to the bar 9 by means of a cord 16 passed through a hole 17 in line with the axis of.the shaft 2: The weight 14 may be traversed on the lever 15 by means of a crank 140 and screw. A fixed stop, 18 near the end of the bar 9 is provided with 9, . slideway 180 receiving the end of a rod 19 having a collar 20 and pivoted to a lever one arm 21<a> of which carries a weight 22 while the other 21<b> carries a sliding weight 23 which may be traversed by a crank 230 and screw. In use, the sliding weight 14. is positioned to give the required load, and the disc 4 turned by hand until the extension 9<a> abuts against the stop 18. The disc 4 is now held and the weight 23 displaced until the end of the rod 19 moves the extension 9<a> backwards. The amount of friction may then be read from the lever arm 21<b>. Friction during rotation of the disc '4 is read when the stop 18 is out of contact both with the collar 20 and with the extension 9<a>. The weight 23 may be moved automatically by a relay energized when the parts 9<a> and 18 contact. Artificially cooled discs 4 may be used when the action of air or water-cooling is investigated. The tests . may be carried out also with a bbricated disc. The slide 6 may be moved to the right so that only part of the surface of the specimen engages the disc thus increasing the load per unit area and the wear. The invention is stated to include a method of measuring wear as a function of time or as a function of time and load per unit area. I

Abstract: 398,524. Preparing hides for tanning. GEIGY AKT.-GES., J. R., 215, Schwarzaldallee, Basle, Switzerland.-(Assignees of Biedermann, R.; 9, Riehenring, Basle, Switzerland.) Feb. 15, 1932, No. 4435. Convention date, Feb. 21, 1931. [Class 76.] Hides or skins are treated with aqueous extracts of animal organs in which the catheptic ferments are the effective constituents. The extracts are made from such organs as liver, spleen, kidneys, the mucous membrane of the stomach or from blood, and the pH value is brought to a value of 4-7, thus providing the optimum condition for the action of the catheptic ferment. Reducing agents such as inorganic or organic sulphur compounds may be added to activate the ferment. The treatment may effect both the de-hairing and the bating of the hides. An advantage of the invention is the avoidance of treatment with strongly alkaline agents ; a preliminary softening with neutral salts may however be employed.
