Title: Torque controlled voluminous set yarns
IPC: D02G1/02
Filed: 1971-06-01
Abstract: 1357139 Modified torque yarns W A SEEM N J STODDARD and R W STODDARD 1 June 1971 [5 April 1971] 18255/71 Heading D1F A method of making set yarn by modifying the torque of an advancing multifilament falsetwist textured yarn comprises overfeeding the false-twist textured yarn through heating and cooling zones in a substantially tensionless condition, and then passing the tensionless yarn through a fluid-whirling chamber in which the yarn is subjected to low pressure fluid to false twist it in a direction opposite to that received in the initial false-twist texturing process, the pressure being controlled to produce a lesser degree of twist than in said first process and collecting the yarn. By 'substantially tensionless' is meant tension sufficient to prevent pigtailing but not sufficient to straighten the crimps in the yarn. The false-twist textured yarn is preferably formed in a continuous process with the set yarn. In a preferred embodiment, an unprocessed yarn Y is led from a supply bobbin 10 via feed rolls 20 and heater 30 to a false twist spindle 40. The false twist textured yarn thus produced is then led directly to feed rolls 50 and heater 60. The heated yarn is led directly to a fluid false twister 80 which imparts a false twist to the yarn in the opposite direction to the twist in the false-twist textured yarn. The modified torque yarn is then takenup on roll 100. The fluid false twister 80 comprises a fluid-whirling chamber 154 having a cylindrical side wall 142 and a fluid inlet passage 152 connected thereto. The inlet passage 152 is disposed tangentially to the side wall and has an axis disposed in a plane perpendicular to the axis of the side wall. The chamber 154 also has end plates 144 perpendicular to the wall axis, the plates 144 having axial bores 148 for the passage of the yarn through the chamber. The fluid stream introduced into the chamber causes the yarn to balloon and also causes the filaments of the yarn to separate. The contact surface of the heater 60 is preferably arcuate to improve yarn/heater contact. The filaments of the yarn may be made of polyester or polyamide. In a preferred embodiment, the false twist imparted to 'the yarn is less than 25% of the twist heat-set in the yarn during the production of the false-twist textured yarn. The modified torque remaining in the set yarn is preferably substantially zero but may be opposite to the normal residual torque of the falsetwist textured yarn. The yarn is preferably used to make knit tricot or knit jersey products.

Apparatus for installing and removing a flow-valve 20 (Fig. 2) in an offset valve seat 18 in a well tubing mandrel has a support 30a on which the valve 20 is mounted. The support is attached to a wire by which it is lowered and raised, and the valve is mounted on a pivoted arm 32 which is retained in the upright position by abutments until a movable member mounted within the support is moved by a downward pull on it, to displace one abutment and allow the arm 32 to be swung outwards by a spring. One embodiment (Figs. 4-8, not shown), is as described in the Parent Specification. In another embodiment (Fig. 9) the movable member 80 which is in two parts connected by a shear pin 86 is spring-biassed upwards relative to the support and the downward pull is applied by pulling on the wire so that a pivoted key-plate 46a jars against a stop 28a. The apparatus is correctly orientated in relation to the valve seat by a guide surface 26a which guides the key-plate into a vertical slot 24a leading to the stop 28a. The apparatus is released by continued pulling on the wire, which shears the pin 86, allowing the support 30a to be raised further, relative to the upper part 82 of the movable member, so that the lower edge of a slot 44a can engage the tapered surface 54a of the key-plate 46a to release it. The valve 20 (Fig. 2) is attached to a conventional handling tool 74.

Abstract: 1,190,821. Cigarette-making machine. INDUSTRIAL NUCLEONICS CORP. 20 April, 1967 [20 April, 1966], No. 18335/67. Heading A2C. [Also in Division G1] The operation of a machine for producing cigarettes having dense ends, said machine forming a continuous tobacco rod 18 containing extra tobacco in locally dense regions R spaced along its length and conveying said rod 18 along a path past a cutter 20 for cutting through each of said dense regions R to form cigarettes 22 with dense ends, is monitored by measuring the density of the rod 18 as it passes a predetermined position along said path relative to said cutter 20 to produce a signal indicative of the density of the dense end regions R, generating a reference signal in response to each cutting operation of the cutter 20 and correlating the density signal with the reference signal to provide an indication of the position of the dense regions R relative to the ends of the cut cigarettes 22. The density of the rod 18 is measured by a gauge 30, of the radiation or capacitance type, which is placed as close as possible to the cutter 20. A reference pulse generator 36 is mechanically coupled to the cutter 20, and comprises either cam actuated limit switches or a photo cell receiving light from a segmented reflecting portion of a rotating cutter axle or hub. Where the spacing between the cutter 20 and the gauge 30 is not an integral number of cigarette lengths, the reference pulses or the measured density signals are passed through a delay device before being fed to gates 32, 34. The resultant gated signals S 1  and S 2  correspond to that portion of the rod 18 immediately before and after the point where it is cut and to the remaining central portion of a cigarette respectively. These signals S 1 , S 2  then pass through averaging circuits 42, 44 and the averaged signals are fed to a difference computer 46 the output signal S 3  of which is fed to a meter 48 which shows a maximum value when exact synchronisation is achieved. A motor 26 drives both the cutter 20 and a known type of dense-ending device 24 via a differential 76 which may be manually adjusted, directly or via a servo 78, to maximize the reading on the meter 48. A reference signal generator 74, preset to a predetermined minimum level for S 3  feeds a signal to a comparator 72 which actuates an alarm 70 whenever the signal S 3  falls below the desired minimum level. The use of an oscilloscope, to determine the direction as well as the magnitude of any deviation from synchronization, is also described.

Abstract: 334,633. Cachemaille, A. S., (Westing- house Lamp Co.). June 15, 1929. Vacuum tubes. - A process for depositing a carbon coating on metals, such as iron, nickel, molybdenum or tungsten, or alloys of nickel or iron with manganese, chromium or copper, which are particularly adaptable for use as grids or anodes in electric discharge devices and for supports therefor, consists in first deoxidizing the metal surface bv heating in a reducing atmosphere and then in an atmosphere containing the vapour of a dissociable hydrocarbon. Finally, the metal is subjected to a prolonged heating in vacuo to remove gases therefrom and to cement the coating to the metal surface. In practice, the metal, mounted in perforated metal or iron or steel containers, is placed in a tube 1 and is heated by a gas or electric furnace 2 in a current of hydrogen passing through a pipe 5A which is formed into two branches and is provided with valves 8 to allow the gas to be fed in at either end of the tube 1. After a temperature of 775‹ C. is attained, a hydrocarbon gas, such as methane, or the vapour of a hydrocarbon, is passed through the pipe 1 by closing a valve 8<A> in the tube 5<A> and opening valves 8<B>, 8<c> to cause the hydrogen to bubble through petroleum ether contained in a. vessel 7, to which is connected a vessel 6 whereby the supply of hydrocarbon is replenished. The temperature of the tube 1 is maintained between 775‹ and 825‹ C., when dealing with nickel, for about an hour, details of gaseous flow and dimensions of heating tubes being given. The flow of gas is reversed at definite intervals by means of the valves 8. After the coated metal has cooled to 500‹ C. in the saturated gas, cooling is continued in a stream of hydrogen only, superfluous carbon being afterwards removed. Adsorbed gases are then removed by heating in vacuo at a temperature. of from 850‹ to 950‹ C., the vacuum being maintained below 0.25 millimetres. Specifications 285,810 and 305,465 are referred to.
