Title: Formation of reserve windings on bobbins in yarn processing machines
IPC: B65H65/00
Filed: 1973-01-31
Abstract: 1464713 Winding continuously supplied yarn PLATT SACO LOWELL Ltd 31 Jan 1974 [31 Jan 1973 23 Aug 1973] 4840/73 and 40055/73 Heading D1J A yarn winding process comprises first delivering the yarn to a yarn collection zone, engaging the running yarn with the bobbin to be wound without halting delivery of the running yarn to the yarn collection zone, and then rotating the empty bobbin to form a reserve winding at one end of the empty bobbin from yarn withdrawn from the yarn collection zone. In one embodiment, Fig. 9, a bobbin tube 47 is mounted on spigots 50 carried by a cradle 52, 53, the cradle having a handle 54 whereby the cradle can be rocked about the shaft 102 to bring the bobbin 47 into frictional contact with a drive roll. When the bobbin tube 47 is fully wound the thread is severed and sucked through the bore of an empty bobbin tube and thence to a suction orifice so that a continually produced thread 41 can be taken up by the suction orifice whilst the full bobbin is removed from the cradle. The fresh bobbin, with the thread extending therethrough, is then moved to a setting between the spigots 50, as shown, the bobbin having a recess 49 at each of its ends so that the thread 41 can continue to be sucked up by the suction means. When the bobbin is in position the cradle 52, 53 is swung towards the drive roll and the winding operation then commences. Some of the thread leading to the suction orifice is wound back onto the bobbin at one end to form a reserve winding. The bobbin may have grooves 48 for such a reserve winding. Thereafter the thread leading to the suction orifice is cut. In a modified embodiment the recesses 49 are formed in the spigots 50 instead of the bobbin 47.  In a modified embodiment, Fig. 2, when a bobbin 15' has been fully wound the thread 31 is cut and led directly to a suction tube 25 without first passing it through the next bobbin to be wound. The completed package is then removed from the cradle 13, 13. The next bobbin to be wound has at one end a pair of axially extending slots 18 terminating in apertures 19. Before this fresh bobbin is placed in the cradle 13, 13 the thread 31 is arranged to pass into one aperture 19 and then out of the other aperture 19. The bobbin can then be placed in the cradle 13, 13 whilst the suction tube 25 continues to take up the thread. The cradle is then swung to a setting in which the bobbin engages a drive roll and the winding operation commences, the thread being caught by a traversing member 21. The bobbin may have a groove 20 for a reserve winding that is drawn out of the suction tube 25.

Abstract: 1281631 Phthalic anhydride CHEVRON RESEARCH CO 3 Feb 1970 [3 Feb 1969 13 Nov 1969] 5201/70 Heading C2C In a process for the production of phthalic anhydride from an aromatic hydrocarbon feed and an oxygen-containing gas in a vapour phase oxidation reactor utilizing a metal oxide oxidation catalyst in a fixed bed having a hotspot zone and an indirect heat exchanger with associated circulating heat exchange fluid as the temperature control means, there is fed to a control system capable of receiving, storing and comparing information relating to parameters affecting the process conditions in the reactor, information relating to (a) the composition of the vaporized effluent product stream issuing from the reactor, and (b) the temperature of the heat exchange fluid; and responsive to a comparison of the stored information the control system causes the required circulation of the heat exchange fluid to be effected, the mode of operation being such that initially the temperature of the heat exchange fluid is adjusted to and maintained at a value in the range from 20‹ to 50‹ F. below the optimum temperature until the composition of the effluent product stream becomes stabilized, and thereafter the temperature of the heat exchange fluid is increased stepwise by from 5‹ to 15‹ F. until the stabilized product stream contains less than 0À5 weight per cent of tolualdehyde-type compounds based on the weight of phthalic anhydride in the product stream, less than 2 parts but greater than zero part of phthalide and/or quinone-type compounds and less than 1 part of unoxidized hydrocarbon feed per 100 parts of phthalic anhydride, thereafter maintaining the thus established operating temperature so long as the product stream composition falls within the aforeprescribed ranges, otherwise resuming the upward incremental adjustment of the heat exchanger fluid as before, said information relating to the product stream composition being determined by means of a vapour phase chromatograph unit. Information on the location of the hot-spot zone may also be fed into the control system. When the hot-spot is within the 60-80 percentile portion of the bed or the phthalide content is not decreased below 2% based on the phthalic anhydride (whichever occurs first), the catalyst may be regenerated by discontinuing the flow of the hydrocarbon feed into the reactor while continuing the flow of oxygen-containing gas for a period in the range of from “ to 1 hour, during which time the bed is maintained at a temperature in the range of from 650‹ to 1000‹ F. The control system may be a digital or analogue device.

Title: Improvements in or relating to apparatus for delivering measured quantities of liquid
IPC: B67D7/08
Filed: 1931-02-23
Abstract: 373,618. Liquid meters; fluid-actuated valves. WHEATLEY, A. R. and BECK & CO., Ltd., 130, Great Suffolk Street, Southwark, London. Feb. 23, 1931, No. 5584. [Classes 69 (i), 69 (ii), and 135.] Liquid meters of the type in which a valve closes to stop the flow after the delivery of a predetermined quantity, are provided with setting means comprising a manually-operated spindle and a one-way clutch, the clutch being adapted to act through a rotary cam free on the spindle for opening the valve, the rotary cam being afterwards returned to allow the valve to be closed by a spring. In the form shown in Fig. 2, the inlet valve g is opened against the action of a spring h, by means of a cam disc r, which is operated through ratchet means from a setting spindle n ; the spindle n is returned to its normal position after setting, and the cam disc is returned to allow the valve to close, by a tappet 3 operated through gearing from the meter valve 7. The stroke of the meter pistons is altered by adjusting the position of the valve seat ring 85. Another form has means to prevent supply during the setting operation, and means whereby the meter may be temporarily stopped, if desired, before the whole of the predetermined quantity has been delivered, and then restarted to complete the delivery. In this form, an auxiliary valve 10, Fig. 3, is provided, which is opened by a member 11 when the spindle n is returned to its normal position after the opening of the valve g. The setting lever o has a pointer o<1> movable over a graduated dial provided with a spring stop 13a so shaped as to permit the pointer to move past it in one direction only. During the operation of the meter, the cam plate r is returned by ratchet mechanism operated from the meter valve 7 through a tappet 3, the latter serving also to actuate indicating pointers 33, 33a, through gearing comprising a clutch 41, 42. At any time during delivery, movement of the lever o serves to move the member 11 to allow the valve 10 to close, but a catch 24 co-operating with a recess 22, Fig. 4, prevents this movement from being large enough to affect the setting of the cam plate r. When the predetermined quantity has been delivered, the valve g closes and a rod 27 moves the catch 24 out of the recess 22 ; the spindle n is thus freed for resetting. During the resetting, the clutch 41, 42 is thrown out by a rod 50, and the pointers 33, 33a are returned to their zero positions by a spring 35. In another form, hand-operated means are operable at any time during delivery to permit the initial position of the parts to be re-attained. The spindle 82, Fig. 9, may be pushed inwards to disengage a clutch member 71 from a worm wheel 69 forming part of the transmission between the meter valve 7 and the cam r, and then turned to rotate a spindle 75 through a ratchet device 81 to return the tappet 3 to its initial position ; the rotation of the spindle 75 also unlocks the spindle n.

Abstract: 1424822 Data storage SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 5 Feb 1973 [16 Feb 1972] 5594/73 Heading G4C A recirculating data store is arranged to store and retrieve data and associated tags in the order in which they are received. The store consists of a shift register M having 512 cells each storing 15 bits in parallel, and registers N and O. The store is divided into two sections, Ml storing four data bits, e.g. dialled telephone digits, and ten tag bits, and M2 storing a single bit. Circuit St enters into register N and the first stage of store M two complementary characters 0101 ... and 1010 ... to indicate the start of a stored sequence. Circuit RT detects the passage of the characters and in response generates signals T and K5. A circuit RCT checks for the presence of only one pair of start characters and, when an error occurs, clears the store and causes a new pair to be entered. Circuit S contains several 14 bit registers storing data which is inserted in the store in the correct sequence, each data item being stored in the first free cell following the start characters. A logic circuit Y is arranged selectively to include and exclude output register O in the store recirculation path. If one of the output buffers R 1 -R m  is free circuit C generates signal K1 to inhibit gates C1-C15 and enable gates D1-D15. The clock pulses CK to register O are blocked at gate P2 and the data in register O is 'read out to the free buffer R. Following the transfer the appropriate buffer R generates a signal B1-B m  which causes circuit C to restore the clock pulses to register O which is thus cleared. Following the next passage of the pair of start characters register O is reinserted into the store recirculation path to form the last cell in the sequence following the start characters. In this way the data is read out in the order in which it was stored.

Abstract: 753,465. Valves. DAVY & UNITED ENGINEERING CO., Ltd. Feb. 19, 1954 [Feb. 27, 1953], No. 5625/53. Class 135. An hydraulic valve comprises a hollow valve member 31 having first, second, and third areas subject to fluid-pressure, the forces acting on the first and third areas tending to open the valve and the force acting on the second area tending to close the valve. The first area which has an effective diameter A is located in the valve inlet 12. The second area (effective diameter B-C) is always exposed to valve inlet pressure through passages 44, 45, 49, 50, 51 leading into and out of the interior 43 of the valve member. The third area (effective diameter B-A) is optionally exposed to the valve inlet pressure through a pilot valve (not shown). The areas are so dimensioned that when all three are exposed to inlet pressure the valve moves to open position and when the third area is open to exhaust or drain pressure, the valve closes. Some of the passages into the space 43 are dimensioned to restrict the flow of fluid into or out of the valve member and so cause the valve member to move at a predetermined speed. As shown, the valve member comprises differential piston 31 with a valve ring 32 secured to one end by a tapered pintle 33 having passages 49, 50, 51 connecting the space 43 within the piston with the high-pressure inlet 12. The valve ring 32 is adapted to engage a seating ring 17 mounted in the valve body 11 between a foundation ring 16 and the end of a cage 14 having a series of triangular outlet ports 15. The ring 16, the cage 14, a liner 18, and a gland ring 23 are all held in the valve body by a bonnet 20 itself secured by studs 25 and nuts 26. The valve member or piston 31 has a part of diameter A sliding in the cage 14 in double packing 19, a part of large diameter B sliding in the liner 18 and itself carrying a packing 37, and a third part of diameter C smaller than A sliding in a liner 22 and a packing 24. The bonnet 20 contains a cushioning pad 21 and is open to the atmosphere through a passage 54. The space 43 communicates with an annular space 42 through a port 45 and a series of ports 44, the ports 44 being cut off by the gland ring 23 when the valve is fully open. The space 42 communicates with an outlet connection 38 leading to a three-way pilot valve through a passage 41 and an annular channel 40. A space 48 on the opposite side of the piston to the space 42 is connected by passages 46, 47 with a connection 39 also leading to the pilot valve so that the space 48 may be connected to exhaust to allow the main valve to close and may be connected through the pilot valve to the high pressure in the spaces 42, 43 to cause the main valve to open.
