Title: Method for Heating a Thermoplastic Yarn
Inventor: CERUTTI GIACOMO
IPC: D01D10/04
Filed: 1968-02-21
Abstract: 1,162,617. Yarn heating apparatus. BEMBERG S.p.A. 21 Feb., 1968 [4 March, 1967], No. 8530/68. Heading B5B. [Also in Division H5] A thermoplastic yarn wound on a supporting tube in the form of a spool, is heated by positioning the wound yarn mass as a dielectric between two electrodes energized by an R.F. voltage having an R.M.S. value of from 1000 to 2000 volts, a frequency between 10 and 200 megacycles and a generator power input between 2 and 6 kilowatts, for a time of from 1 to 10 minutes. Either field electrode of the R.F. field may be formed by the metal tube which supports the yarn spool, which tube is preferably made of aluminium, but may also be made of other metals, e.g. steel. The second electrode is preferably made of copper. Specified thermoplastic materials include polyamides, including polyhexamethylene adipamide, polycaprolactam and polyurethanes, polyesters, especially polyethylene terephthalate, polyolefins and polyvinyl materials. Thus, in Fig. 1, 1 indicates either field electrode, having a cylindrical configuration, the yarn spool 2 being placed in the interior of said electrode. The metal tube 3, on which the yarn is wound, acts as the second field electrode. Electrodes 1 and 3 are inserted in the supporting plate 4, in the interior of which they are connected to the coaxial leads 5 and 6 through which the R.F. voltage is fed. In Figs. 2 and 3, electrodes 1 and 2 are so shaped as to exhibit annular projections 3 and 4. The yarn spool 5, having a cylindrical supporting member 6 made of a non-metallic material, is positioned between electrodes 1 and 2 so that its sides directly contact the annular projections 3 and 4 of the electrodes. In addition, to the electrodes 1 is affixed a cylindrical block 7, of a non-metallic material, intended to support the spool 5. Electrodes 1 and 2 have, on their bottom portion, two coaxial plugs 10 and 11 which permit insertion into, and withdraw from, the coaxial sockets 8 and 9 formed in the supporting plate 12, the electrodes and spool assembly. The coaxial plugs 8 and 9 are connected, in the interior of bedplate 12, to coaxial leads 13 and 14 through which the R.F. voltage is supplied. Continuous treatment processes may also be effected. Thus, for example, the yarn spools may be arranged in a horizontal row on a conveyer belt or another like member which, being moved in a continuous run, causes the yarn spools sequentially to be passed between two confronting plate electrodes, energized by an R.F. voltage, the spatial velocity of the spool being calculated so that each individual portion thereof is subjected to the heat treatment for a time whose duration is roughly that required in the stationary treatment for producing an acceptable reduction of residual shrinkage. Examples are given, relating to the use of the apparatus for the reduction of residual shrinkage in yarns of polyamide and polyester materials.

March 3, 1964 [March 4, 1963], No. 8925/64. Heading DID. [Also in Division G3] In a spinning machine in which the spindles and the flyers are driven and their drive shaft 3, 4 are connected to a differential 7, signals are fed from one or more of the moving parts of the machine to an electronic controller 27 (enclosed within the dashed line in Fig. 1) for controlling the drive to the differential, the traversing elements and the feed and delivery rollers of the drafting head. As shown, hydraulic motors 23, 24 which drive shafts 3, 4 are driven by a pump 14 of adjustable capacity. Alternatively motors 23, 24 are driven by separate pumps. Motors 39, 34, 57, 9, 10 for driving the feed rollers 12, delivery roller 11, differential 7, and the spindle rail traverse mechanism respectively are driven by a pump 16 which is arranged to maintain a constant output pressure. A tachometer device 26 on shaft 4 feeds a signal into controller 27 to act as a basic signal from which signals representing the desired speeds of the other driven components of the machine are derived. Each of these signals is then compared with a signal derived from a tachometer associated with the appropriate drive and the drive is adjusted to bring the actual and desired values together. For the shaft 11 of the delivery roller the signal corresponding to the desired speed is fed in at 31. compared in a device 32 with the signal from a tachometer 33 and a servo-valve 35 is adjusted as a result of the comparison to regulate the speed of motor 34. The signal for the feed roller is taken from the tachometer 33. Adjustable devices 30, 37 allow the desired speeds of delivery and feed rollers to be adjusted. The basic signal from tachometer 26 is also fed to a part of the controller which contains an integrating device 43, 44 and issues the signals which determine the speed of the differential drive shaft 8 and the speed and reversal points of the traversing mechanism. By using the adjustment devices in the controller the shape of the package can be selected and the amount of material wound before a signal is given to end the wind, adjusted.

Filed: 1917-06-29
Abstract: 128,246. Armstrong, Whitworth, & Co., Sir W. G., and Simson, G. June 29, 1917. Ordnance muzzle shutters.-Relates to means for actuating muzzle shutters, particularly those used with guns mounted on submarine vessels, and consists in employing near the muzzle of the gun a power cylinder with two pistons, the shutter being carried by one of the piston-rods and actuated by the other. Fig. 3 shows the shutter I pivotally mounted at J on a cross-head E sliding in guides F beneath the gun muzzle. The power cylinder A has a rear piston B connected by its rod D to the cross-head E and a front piston C, the hollow rod G of which is connected to an arm H on the shutter. When pressure fluid is admitted to the cylinder A through a flexible pipe K, the pistons B, C move forward together and slide the shutter from its housed position below the gun muzzle. The piston C moves forward alone when the piston B reaches the by-passes N, and the shutter is then rocked on its pivot J to close the muzzle. The parts are returned when pressure fluid is admitted to the front end of the cylinder by a flexible pipe L, the piston C being sufficiently long to render the by-passes N inoperative,
