Title: Improvements relating to the control and like fittings of steam plant
IPC: F22D11/00
Filed: 1924-11-05
Abstract: 224,881. L÷ffler, S. Nov. 13, 1923, [Convention date]. Temperature, regulating.-A valve on a boiler is provided with a condenser through which a cooling medium is circulated to ensure the accumulation of water at the valve to protect it from damage by contact with steam. The valve A controlling the delivery of steam from a boiler D is placed in a downwardly-extending pipe R surrounded by a cooling-jacket K to ensure the accumulation of water at the valve when it is closed. Water may be supplied to or withdrawn from the pipe by a pump. According to the Specification as open to inspection under Sect. 91 (3) (a), the condenser is replaced by heat-radiating fins. This subjectmatter does not appear in the Specification as accepted.

Abstract: 685,169. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and SCOWCROFT, J. Oct. 11, 1951 [Oct. 31, 1950], No. 26495/50. Class 40 (iv). In a system in which the normal final-selectors have a separate outlet for each subscriber on a party-line, the wanted subscriber is rung from a code-ringing circuit individual to the party-line and including a switch set in accordance with the outlet selected. As shown, the - and P wires of the outlets are commoned while the + wires go to a bank of the switch CF which is started by IC when the party-line is seized and hunts for ringing return potential. Alternatively the switch may hunt over separate P wires. Relays CD, CDR pull up and put ringing relay RS under the control of the ring start and ring hold wires so that it is operative-for periods lasting a little longer than the longest ringing code. During each period, relay AC is controlled over the code ringing conductor selected by CF to ring the party-line. Upon reply, feed relay A energizes when RS is back, connects up B and closes a loop for operating F and D in the final selector. At the end of the call, the switch CF remains in its set position.

[Class 8 (ii).] Gases. such as krypton, less volatile than oxygen are extracted from air by subjecting the crude gaseous oxygen evaporating at the base of a rectifying column to washing by a reflux oi liquid oxygen freed from krypton &c. and obtained by the condensation of the gaseous oxygen. The Figure shows apparatus in which the gaseous oxygen rises through tubes 5 cooled by the outflowing gaseous nitrogen ; pure gaseous oxygen passes out at the top of the tubes, while the liquid becomes enriched in krypton &c. and flows back into the vaporizing vessel of the rectifier, the liquid in which is thus enriched and may be drawn off and worked for krypton &c. when sufficiently concentrated. In a modification, the gaseous oxygen passes into a second rectifying column in which a reflux of condensed oxygen is effected, the. krypton &c. accumulating in liquid form at the bottom of this column and being drawn off from the evaporating vessel at the bottom in a gaseous form.

The valve member 32 is slidably mounted in a tube 34 integral with a cap 16 screwed on to the container neck 14, and the lateral projection 58 keys the valve member 32 to the fixed tube 34. The safety ring 56 is secured to the fixed tube 34 by flare 72, but can rotate thereon. A tapered pin 50 carried by posts 46 on the fixed tube 34 closes the lower end of the valve member 32. Rotation of the safety ring 56 to bring indicia on the flange 40 and on the ring 56 into alignment permits raising of the valve member 32 by means of the flange 40. In another embodiment, Figs. 7-9, an aerosol valve 86 is operated by downward movement of an actuator 90 provided with a nozzle 92. The rotatable safety ring 96 protrudes through a snap-fitted cover 116 so that raised indexing tabs 118 and 120 may be angularly aligned to permit opening of the valve controlled by valve member 86. The safety ring 96 is provided with a tubular stem 100 whose upper end 101 abuts a radial locking projection 102 on the actuator 90. The upper end 101 has a release notch which can accommodate the projection 102 when the tabs 118 and 120 are aligned so that the valve may be opened. In a further embodiment, Figs. 10 and 11 (not shown), the cover 116 is omitted, and there is no nozzle 92 projecting beyond the actuator 90. The safety ring 96 does not project outwards beyond the flange 110.

A reversible pump or engine has sliding- rocking vanes 31, which engage with barrelshaped slots 28, in a rotor 24, and vane extentions 30 provided with cut-away portions 42 to facilitate the passage of fluid into and from the working chamber 15. For a pump, inlet and outlet ports 36, 40 are less than the width of the working chamber, peripheral portions 38, 39 of the latter providing bearing surfaces for the arcuate portions of the vanes. A groove 47 allows escape of fluid trapped in front of a vane, after the leading edge of the latter has cut off the outlet port at a point 44. A similar groove 50 is used when the pump is reversed. The rotor is secured to the shaft 18 by splines 27, in grooves 26, which provide a limited amount of freedom for the rotor to rock about an axis 1-1, should there be any irregularity in the faces 16, 17 of the end walls 10, 13. The splines are also tapered as shown, Fig. 2. Each vane may be pressed outwards by a spring-pressed plunger. Fig. 5 (not shown). The inner end of a vane may be beaded, Fig. 6 (not shown). The capacity of the pump, or engine, may be varied by varying the eccentricity of the rotor 24 in its casing.
