Title: Improvements in or relating to air compressors
IPC: F04B39/00
Filed: 1947-11-28
Abstract: 649,585. Air compressors. SJOBERG, E. Nov. 28, 1947, No. 31568. Convention date, Nov. 13, 1944. [Class 8(i)] [Also in Groups I and XXIX] A hydraulic air compressor comprises a hermetically sealed cylinder having an air reservoir 2, a working chamber 1, and a water - discharge chamber 3. The reservoir 2 mounts a pressure gauge 34, is fitted with an air consumption duct 35, and communicates through a non- return valve 33 with the chamber 1. The chamber 1 communicates through a pipe 24 with a chamber 23 having a piston or diaphragm which controls a water inlet valve 19, and through a discharge valve 12 with the chamber 3, is supplied with air through a filter 28 and a valve 27, and water through a valve 17, the valve 19, and a float - actuated, safety cut - off valve 21. The chamber 3 has a perforated scoop 37 carried on a lever 39 and collecting the discharge from the valve 12 to close the valve 17. At the commencement of the cycle of operations, the valves 17, 19, 21 are open whilst the valves 12. 27, 33 are closed. Water enters the chamber 1 and first raises an auxiliary float 15 to close an outlet 13 from a float chamber 4 housing a float 7 connected by a spring 10, a pin 9, a rod 6 passing through a float guide tube 5, and a spring 11 with the discharge valve 12, and connected by the rod 6, and a lever 30 to the air inlet valve 27. As the water level rises in the chamber 1, the air therein is compressed and passes through the valve 33 into the reservoir 2 until a predetermined pressure in the chamber 1 is reached whereupon the valve 19 is closed by their pressure acting on the diaphragm in the chamber 23 against the spring 22. On air being consumed, the pressure in the reservoir 2 falls whence the valve 19 reopens to admit more water to the chamber 1. The water level rises until the working pressure is again reached, this operation going on step by step until the water reaches the upper rim of the float chamber 4. Water then enters the float chamber 4 to raise the float 7 against the spring 10 and, through the rod 6 and lever 30, opens the air inlet valve 27, and through the rod 6 and the spring 11 opens the discharge valve 12. The water discharging from the chamber 1 sucks in air through the valve 27 and at the same time falls into the scoop. 37 to close the valve 17 which remains closed until the chamber 1 is substantially emptied of water. As soon as the water falls to the level of the float 15, the float chamber 4 is drained to permit of the repetition of the cycle of operations. The valve 21 is actuated by a separate float 45 and serves as a safety cut-off valve should the level of the water in the chamber 1 rise unduly. In a modification, the float chamber 4 is mounted on the upper end of a tube and communicates therewith through a restricted orifice, the valve 12 being arranged to discharge water from the lower end of the tube to drain the chamber 4 as well as from the chamber 1.

Title: Fasciated yarns
IPC: D01H15/00
Filed: 1975-07-30
Abstract: 1486766 Producing a fasciated yarn by fluid false twisting; Sliver conductors and guides TORAY INDUSTRIES INC 30 July 1975 [9 Oct 1974 22 Nov 1974 19 Feb 1975] 318252/75 Headings D1D D1F and D1N A fasciated yarn, i.e. a yarn having surface staple fibres helically coiled around a bundle of substantially parallel and non-twisted staple fibres, is produced by feeding a bundle of staple fibres through a nip (formed by rollers 4, 4') with some loose staple fibres arranged alongside the bundle, passing the fibre bundle and the loose fibres through a false twisting fluid vortex nozzle 12 and winding up the yarn on roll 23, the fluid producing a suction effect at the inlet 9, Fig. 3, of the nozzle at least when starting spinning, further suction being applied by suction means 18 to branch tube 10 of fibre inlet 9, this further suction being cut off when starting spinning. The fibre bundle is twisted between the nip of rolls 4. 4' and nozzle 12 and untwists between the nozzle and nip rolls 22, thereby twisting the previously loose fibres to give a drafted fasciated yarn. Preferably guides 5 limit the spread of the loose fibres in the horizontal direction and belts 7 limit spread in the vertical direction. The vortex is produced by fluid passing through channels 15. The'smaller the angle # the larger the suction effect exerted on the fibres but the smaller the twisting action. # is preferably 40 to 55‹. Alternatively an additional tube (16' Fig. 4 not shown) supplies fluid to additional channels (15') which are tangential to passage 13 and thus causes twisting without suction. Fluid is supplied to tube 16 only when starting spinning and thereafter to tube (16') only. The suction applied to tube 10 serves to draw off these fibres in the event of yarn breakage. When starting or restarting spinning the fibres are sucked down tube 10 until its extension, tube 17 is temporarily blocked. The fibre bundle is then sucked through nozzle 12. As shown tube 17 is flexible and is blocked by squeezing. Alternatively it may be closed by a shutter (31, Fig. 5, not shown). For the fluid vortex nozzle 12 to commence to spin the fibre bundle as tube 17 is blocked the fibres should be longer than the distance L2 between the nip rolls 4, 4' and the twisting point, e.g. at least 3 inches long. To enable shorter fibres to be used a temporary nip may be produced nearer the twisting point by raising roller "32, Fig 7A on arm 33 so as to press a portion of belt 7against belt 7' a cable 39 allows this to be done simultaneously with the blocking of tube 17. In the embodiment of Fig. 8, not shown, roller 6, about which belt 7 travels, is raised to produce a temporary nip at rolls 6, 6'. A circuit is provided so that in the event of a yarn breakage registered by detector 24, Fig. I the pomer is cut to the fibre feed rollers and then to the fluid supply motor. Alternatively it may be used to stop the machine without breaking the yarn.
