Filed: 1960-01-19
Abstract: 945,141. Valves. G. DION-BIRO. Jan. 19, 1960 [Jan. 30, 1959], No. 1960/60. Addition to 865,220. Heading F2V. A pressure regulating valve comprises a valve body 50 provided with an elbow duct 51, 52, the upstream branch 51 being adapted for connection with a liquefied gas container B, while the downstream branch 52 is connected to a delivery pipe C, the branch 52 and bore of the delivery pipe C being of constant cross-sectional area. A cylindrical valve member 53, connected to a diaphragm 55, is located in a bore opening into the bend of the duct and in axial alignment with the upstream passage 51. The valve seat is formed on the inner end of the duct 51 and the valve is normally urged to its open position by a spring 63, in which position it abuts a boss 67 on an end cover 60. A passage 64 leading from the downstream passage 52 of the elbow duct supplies fluid to a chamber 59 to act on the diaphragm 55 in opposition to the spring loading. In operation, the valve is normally held in its open position by the spring loading, as shown, and the liquefied gas is supplied to the outlet pipe C through an unobstructed passage of constant cross-sectional area. If due to a condition in the outlet pipe 3 the pressure in the passage 52 suddenly rises, this increased pressure will be communicated to the chamber 59 and act on the diaphragm to close the valve. Immediately the effect of this condition ceases and the pressure in the delivery pipe falls, the valve again opens to allow the uninterrupted flow of the gas.

Title: Improvements in or relating to yarn winding machines
IPC: B65H54/16
Filed: 1927-01-25
Abstract: 289,173. Palmer, H., and Palmer, W. Jan. 25, 1927. Winding-machines; clearing-apparatvs; stop - motions. -In a yarn-winding machine of the vertical-spindle type employing a pawl and ratchetwheel 45, 46, Figs. 1 and 3 for rotating the screwed rod 47 along which the nut device 48 carrying the yarn-guide 38 is fed, a bluff 69 is normally held out of action by the running yarn but on yarn failure operates to disengage the pawl 45 from the wheel 46 and thereby stop the feed of the guide 38. The yarn normally supports a guide pulley 37, but on breakage of the yarn the pulley falls and through a finger 71 lifts the segmental end 69<a> of the bluff 69 into contact with a pin 70 to disengage the pawl 45 and wheel 46. The builder-mechanism is also arrested by a stop-mechanism adapted to be rendered active by abnormal conditions of the running yarn. The stop-motion includes a spring- actuated plunger-rod 3 operated by excessive tension or a like drag in the yarn 34 to disengage the friction-discs 11, 13. The rod 3 is held set by a pin 21 engaging the end of the sleeve 2 and is released by a turning movement bringing the pin 21 into register with a slot 22 in the sleeve 2, the rod then rising under the action of the spring 5 to disengage the discs 11, 13 and to apply a brake 17 to the bobbin 19. The yarn passes from the hank 35 through a slit-clearer 31 having a guide-wheel 32 and successively over or through guides 33, 36, 37, 38 to the bobbin 19. Under normal conditions the parts are as shown in full lines in Fig. 1. When the clearer 31 is obstructed, or under undue increase of tension, the pivoted frame 25 is depressed and engages the inclined end of the vertical rod 39 moving it to the dotted position and turning the rod 3 through the link 44 connected to the arm 10 to stop the bobbin 19. The movement of the rod 3 also serves to disconnect the gain mechanism. When the rod 3 is turned, an arm 7 thereon tilts an abutment 51 out of the path of a screw 50, with which it normally makes contact on each reciprocation of the lifter rail 52 to advance the pawl 45. The member 51 is carried in a pivoted bracket 53 normally held vertical by a weight 56. Specification 208,870 is referred to.

Abstract: 606,988. Liners for gun barrels. MAGOS, J. P. Jan. 22, 1946, No. 2166. [Class 92 (ii)] The tapered liner for a gun barrel is formed integrally with a flange which has a number of spaced-apart threaded and unthreaded apertures, the latter serving for the passage of bolts which engage the barrel and thereby hold the liner in position, while the former receive the bolts, after their removal from the unthreaded holes, the bolts then bearing against an end surface of the barrel and serving to withdraw the liner axially from the barrel. In Figs. 1 and 3 the gun barrel 1 has a tapered bore 2 in which a tapered liner 3 fits, the liner being held in position by a bolt 7 which passes through holes 8 in a liner flange 6 and screw into the barrel at 9. The front of the liner is rounded at 5 and makes a gas-tight seal with a corresponding groove in the barrel. To remove the liner the bolts are removed from the holes 8 and are screwed into tapped holes 10 in the liner the screws then bearing against the end of the barrel and forcing the liner to the rear. In a modification, Figs. 4-6 (not shown), the liner is of oval section near the flange as a safeguard against rotation, and the flange fits in a counterbored hole at the rear end of the barrel.

IPC: F24C3/10
Filed: 1967-01-16
Abstract: 1,177,771. Gas burner ignition and control. INSTITUT MOSGAZPROEKT. 16 Jan., 1967, No. 2201/67. Headings F4F and F4T. An infra-red radiation gas burner 4 has ignition and control apparatus comprising valve 3 with a gas inlet 11 and supplying gas to a main burner nozzle 13 and a pilot burner 9, and a bi-metallic element 1 extending partly into the burner zone 7 and being adapted to engage a valve rod 2 to permit gas flow only when the element is heated, wherein when self-holding switch 34 energizes the circuit containing normally closed contacts 35 a coil 8 heats element 1 causing it to contact rod 2 thereby opening the gas passages to the pilot burner and nozzle 13. Igniter coil 10, in series with heater 8, ignites the pilot burner and also the main gas/air mixture through hole 24 after the mixture has passed through radiating element 23. When the valve is fully open gas is only supplied to nozzle 13 and the element 1 opens contacts 35 whereby switch 34 is de-energized. The heat of the burner on that part of element 1 extending into zone 7 causes the element to keep valve 3 open. When the burner is operating normally signal lamp is not energized. To cut off the burner, switch 34 is closed to energize the circuit containing heater coil, 20. A second bi-metallic element 18 is then heated which forces element 1 away from rod 2 thereby closing the valve 3. A programming device 39 may be used to automatically control the burner. In the embodiment of Fig. 2 the gas to main burner nozzle 13 by-passes valve 3 and is controlled by a pneumatic valve 25. On operation of the burner when gas is supplied to pilot burner 9 the increase in pressure in chamber 12 is transmitted to chamber 27 of valve 25 via line 28 and the pressure on plate 29 opens this valve allowing gas to pass to nozzle 13. In the embodiment of Fig. 3 (not shown), a plurality of burners 4 arranged in series are all fed from a single pair of valves 3, 25. Associated with the element 1 of each extra burner is a nozzle (42) connected with chamber 27 and via a throttle with chamber 12. In the event of one of the extra burners going out the corresponding nozzle 42 is closed by the element 1 and the gas supply to all the burners is cut off.
