Title: Improvements in multiple sight-feed pressure lubricators
IPC: F16N25/00
Filed: 1922-10-16
Abstract: 193,816. York, R. S. Feb. 23, 1922, [Convention date]. Fluid-actuated valves.-In a lubricator comprising a number of sight-feed units fed with oil under pressure from a common source, each unit is provided with a valve operating, when excess flow of oil occurs, to close the connection between the sight-feed chamber and the delivery pipe, and is provided also with a valve which is opened when excess of oil flows to permit oil to escape visibly to the atmosphere. Above the chamber 11 of each unit a sleeve 20 is screwed into the body 10, the sleeve being bored to receive a plunger 26 which is grooved on its periphery so as to be oil and steam tight. The plunger has an axial bore 26<a> which is formed at its upper end to provide a seat for a ball-valve 28 housed in a chamber 20 formed in a plug 30 screwed into the body above the sleeve 20. An outlet pipe 34 communicates by a passage 33 with a space 32 between a closure plug 31 and the plug 30, the space 32 communicating with the chamber 29 by a channel 35, the lower end of which is formed to provide a seat for the valve 28. A ball-valve 37 housed in a chamber 36 formed in the upper part of the plug 20 at the side of the plunger 26 normally closes a passage 38 communicating through an annular groove 39 with a passage 40 extending through the wall of the body. The diameter of the bore 26<a> is such that it permits the normal flow of oil, but if an excess flow of oil occurs the oil does not flow freely through the bore but raises the pressure in the sight-chamber 11 and causes the plunger 26 to be raised, which causes the valve 28 to close the passage 35 and stop the flow. In rising, a shoulder 41 on the plunger 26 dislodges the valve 37, permitting oil to escape through the channel 40, giving a visible indication of improper adjustment of the valve 16. To restore the valve 28 and plunger 26 to their normal positions after adjustment of the valve 16, should they tend to stick, a spring-pressed rod 48 is used. The rod 48 carries a valve 42 seating against a nipple 43 to prevent leakage of oil along the rod.

Title: Apparatus for the back motion of the cone drum belt in a flyer frame
IPC: D01H1/36
Filed: 1957-09-09
Abstract: 842,472. Flyer frame winding-on motions. HOWA KOGYO KABUSHIKI KAISHA. Sept. 9, 1957 [Sept. 14, 1956], No. 28420/57. Class 120(2). In apparatus for the return movement of a cone belt 3, Fig. 1, connecting cones 2, 3 in a flyer frame, a release mechanism is provided for disconnecting a main drive transmission to cone 2, and an auxiliary drive mechanism is provided for driving cone 3 while the frame is stopped and a return mechanism effects return of the rack 14 and anchor bar to their starting positions. As shown, a main motor M, controlled by ON and OFF push-buttons in a box f, Fig. 1, drives, through gearing, the drive shaft 1 of the top cone 2. During winding, drive to spindle 52, Fig. 2, is compounded of a uniform speed component from motor M via gears 72, 40 to outer gear 42 of a differential and a decreasing speed component via cones 2, 4, gearing to shaft 41 and sun wheel 43, the planet carrier 44 being connected to spindle 52 via a swing mechanism 45, 46, 47. When bobbin winding is complete, the end 27 of a knock-off bar 25 closes a switch a to stop the machine, A switch g is then operated to energize a magnet h and thereby open clutches 6, 7 which cut off the main drive to the top cone 2 and the drive from the bottom cone 4 to the bobbin. Under these conditions, the machine can be inched, by pressing a push-button IN, with the flyer and bobbin rotating at the same speed to feed forward a loop of roving. A pushbutton J is now pressed to energize an auxiliary motor m and cause.it to drive the bottom cone 4 to facilitate backing the belt 3 to its starting (right hand end) position by reverse movement of the long rack 14; this is effected by motor m via a chain drive 20c, a worm 19 and worm wheel 18, the latter being clutched to the vertical ratchet shaft 12 by operation of a magnet n, also energized by push-button J. Just before the end of the rightward movement of rack 14, it restores bar 25 to its original, hooked, position, thereby opening switch a and also a switch u which de-energizes'motor m and magnet n. Switch g is now opened, so that clutches 6, 7 are re-engaged, and the frame can be re-started for another winding by pressing the button ON. By driving cone 4, the backing of belt 3 can be effected without releasing the belt tension. This tension may be provided by a compression spring 37, Fig. 4; one end of the spring bears against a nut on a screw 34 supported by a bracket 36, and the other end bears on a case 32 pivoted at 33 to a lever 31 which supports cone 4 and is pivoted at 30. As modifications, a uni-directional coupling may be substituted for clutch 6, and the driving of shaft 12 and cone 4 may be effected by different motors.

Abstract: 989,765. Making polyacrylonitrile fibres. DOW CHEMICAL CO. July 19, 1963, No. 28612/63. Drawings to Specification. Heading B5B. In making polyacrylonitrile fibres by polymerizing a monomer containing at least about 80% acrylonitrile in an aqueous saline solvent for the polymer to directly form a spinning solution of the polymer, extruding the solution into an aqueous spin bath containing the same salt or salts as the spinning solution but at a lower concentration so that the polymer is coagulated to form filaments withdrawing the filaments from the spin bath, washing them with water and maintaining the concentration of the salt in the spin bath at a non-polyacrylonitriledissolving level with the water used for washing the fibres, a corresponding volume of spin bath is withdrawn, concentrated to a polyacrylonitrile-dissolving level, and returned to the zone in which fresh acrylonitrile monomer is polymerized and fresh spinning solution formed simultaneously. Substantially all the water required for the fibre-making process is that which has been used for washing the fibres withdrawn from the spin bath. Every step in the process is preferably continuous. The salt used in the process may be zinc chloride. The spent spin bath may be concentrated by evaporation. The aquagel filaments withdrawn from the spin bath are preferably washed in a countercurrent stream of water. The proportion of acrylonitrile in the polymer is preferably 90 to 95% by weight. A list of monomers which may be. copolymerized with the acrylonitrile is furnished. When the salt in the spinning solution is zinc chloride, the pH of the solution is adjusted by addition of hydrochloric acid to such an extent that the pH of the solution when diluted tenfold with water is below 4 and preferably from 2 to 3. The copper ion content of the solution is preferably adjusted to a value of from 0À03 to 0.5 parts per million and its dissolved iron content maintained at a concentration lower than about 10 parts per million, particularly when hydrogen peroxide is to be used as a catalyst promoter. Specifications 725,751 and 786,139 are referred to.
