Title: Burner Nozzle.
Inventor: KUNIOKA KAZUO
IPC: F23D14/78
Filed: 1969-01-01
Abstract: 1,196,892. Burners. NIPPON KOKAN K.K. 1 Jan., 1969, No. 154/69. Heading F4T. A burner nozzle, which can be used first to melt a cold charge and then rapidly converted to an oxygen lance, has four flexible vanes 11 each secured at one end 17 to a tube 3 and at the other end 18 to a sleeve 2, which is rotatably secured about a fixed inner tube 1 concentric with tube 3, so that rotation of the sleeve twists the vanes to impart a rotational component of velocity to fluid leaving the annular space 4 between the tubes. For melting operations, the vanes may be twisted, the tube 3 is supplied with oxygen or oxygen enriched air via a port 9, and the tube 1 is supplied with fuel, fluxing agents or other additives, mixing of the fluids near the outlet 24 being assisted by a Venturi 23. The shape of the flame depends on the degree of twisting of the vanes, and if the maximum imparted rotational component of velocity is greater than the longitudinal velocity, a region of reverse gas flow is produced beyond the nozzle, Fig. 4 (not shown). When the vanes are straight, extending longitudinally of the nozzle, and oxygen only is supplied to tube 3, the nozzle is used as an oxygen lance. A rotatable member 12 lies between two flanged parts 13, 14, is connected to the sleeve 2 and carries a handle (not shown) for effecting rotation of the sleeve. Member 12 is threaded on part 13 with a thread of such a pitch as to compensate for the shortening of the longitudinal distance between the ends of the vanes as they are twisted. Alternatively, Fig 2 (not shown), the sleeve 2 is made of two parts keyed together non-rotatably, for telescopic movement. A cooling system 5-8 is provided about the nozzle.

Filed: 1974-01-04
Abstract: 1417953 Semi-conductor devices SIEMENS AG 4 Jan 1974 [8 Jan 1973] 00366/74 Heading H1K A thyristor comprises an annular main emitter 1 and an additional emitter zone 12, the additional zone having two apertures therein through one of which an ignition electrode 6 contacts the first base region 2, a further electrode 8 contacting the base 2 through the other aperture, the second base region 3 possessing a region 10, of low breakdown voltage, situated beneath the further electrode, and the structure enabling an overhead voltage to ignite the device without damage. The further electrode 8 is in electrical connection with the main emitter electrode 5 via either a line 9 or regions of the device. A resistor 20 in the line connection helps the current flow caused by overhead ignition to be dispersed to the main emitter 1, as shown by the arrows, so switching on the device. Normal ignition initially causes the auxiliary emitter zone around the electrode 6 to conduct, and this ignites the main emitter 1. The region 10 may be of lower resistivity, or may be thinner, than the remainder of region 2, to produce the lower breakdown voltage. In alternative embodiments, the further electrode may extend towards the main emitter electrode 5 through an aperture in both electrode 13 and zone 12, the material between electrodes 8 and 5 constituting the resistor 20.  Reference has been directed by the Comptroller to Specification 1,360,326.

Title: Improvements in or relating to liquid level regulators intended particularly for use with steam boilers
IPC: F22D5/10
Filed: 1946-01-07
Abstract: 628,175. Fluid-pressure servomotor-control systems. HILLIER, H., and WEIR, Ltd., G. & J. Jan. 7, 1946, No. 494. [Class 135] A steam generator feed water control valve is subject tc generator pressure, feed water inlet pressure, and a control pressure, all acting differentially, the control pressure being variable by means of leak-off needle valves which are actuated in accordance with the water level in, and the stream flow from, the generator, the leakage water from the valves flowing in parallel to the generator, and a third needle valve is operatively connected with the feed valve and varies the control pressure in conformity with the opening of the feed valve. In an embodiment, the feed water inlet valve 3 carries differential pistons 4, 6 and the valve itself is subject to inlet pressure on its lower face and outlet or boiler pressure on its upper face. The water inlet 2 is in communication with the upper face of piston 6 through a passage 6<SP>11</SP> and with the lower face of piston 4 through a passage 6<SP>1</SP> and around the piston itself. The flow through passage 6<SP>1</SP> is controlled by a throttle 14 which, besides being adjustable in position, variably constricts passage 6<SP>1</SP> according to the position taken up by valve 3 and its pistons. The chamber 8 below piston 4 constitutes a control chamber, the pressure in which is controlled by two needle leak-off valves, one actuated by a float responsive to the water level in the boiler and the other, by an adjustable spring-loaded bellows of which the interior is subject to steam pressure at the outlet of the superheater, and the exterior is subject to the steam pressure in the boiler. The bellows is thus subject to differential pressures indicative of the load on the boiler. A screw-down spindle 11 enables the valve 3 to be closed by hand. In a modification, the inlet 2 is in full communication with the underside of the lower piston carried by valve 3 and the control chamber 8 is situated above the upper piston. A passage throttled by a needle valve leads from the under-face of the lower piston to the control chamber. Specifications 376,873, 394,547, 418,208 and 541,449 are referred to.

Title: Improvements in pistons
IPC: F16J1/04
Filed: 1920-01-10
Abstract: 153,802. Goold, L. W., (Stark, O. G.). Jan. 10, 1920. Piston packing; pistons.-A piston comprises a ring portion divided into segments and means for putting the segments under expansion strain in circumferential direction, so that the piston presses against the wall of the cylinder. In one form, the piston comprises two rings 1, 2 connected by members 3 carrying bosses 4 for the wrist-pin 8. Each member 3 is cut nearly halfway through at 5, and these cuts are intersected by cuts 6 in the ring, so that the ring 2 is divided into two segments. The bearings 7 for the pin 8 are slightly inclined downwards, so that when the pin is inserted the members 3 are bent outwards, and the segments are moved circumferentially with respect to the ring 1. Before or after the insertion of the pin 8, the segments are forced down into the position shown in Fig. 4 to close the cuts 5, and are then treated, as by heating, to fix them in that position. The top of the ring 2 is then finished to a smooth surface to receive the head 9. The head 9 has a flange 10, which may carry a flange 11 to engage a groove in the ring 2 to lock the head in position. Keys 12 may be seated in slots in the ring 2 and engage notches in the flange 10. The diameter of the ring 2 while in tension is slightly larger than that of the cylinder, so that the piston, when inserted, will press on the cylinder walls.
