Patent GB-119500-A (GB)
Title: Improvements in or relating to Instruments for Indicating Fluid Pressures.
Inventor: RUMNEY HOWARD
IPC: G01L7/18
Filed: 1917-09-27
Abstract: 119,500. Rumney, H. Sept. 27, 1917. Indicators actuated by pressure of head of liquid. - Fluid - pressure indicating - apparatus adapted to determine the depth of sea or other water or to indicate the variations therein, comprises a long mercurial pressure tube of barometer type, the reservoir of which is protected from the surrounding medium, indications of the depth being given by a coiled resistance wire carried in the barometer tube and partially immersed in the mercury. The tube 1 is connected to the reservoir 2 by a perforated sleeve 42 and is closed at the ends by plates 8 held in position by a rod 6 and nuts 9. The lower ends of the reservoir is mounted on a base-plate 3, the junction between the tube and the base-plate being closed by a rubber washer and a nut 10 together with a cap 11 screwed to the end of the tube. A second cap 12 secured by screws to the base-plate is providedto cover the whole. Surrounding the barometer is a tubular member 15 connected by supporting arms 18 to extensions 4 of the base-plate and secured at the lower end to a casing 14 enveloping the reservoir 2. Coiled round the upper end of the rod 6 is a resistance wire 7, one end of which is connected to the rod and the other to the inner member of a cable 33, the outer member making contact at 32 with the frame of the apparatus. An aperture 40 in the casing 14 allows entrance of the sea water, the contained air serving to protect the mercury in the reservoir 2. Variation in the depth of water causes the mercury to rise and fall in the barometer, thus short-circuiting part of the resistance wire 7 which preferably forms one arm of a Wheatstone bridge. A second instrument subjected to atmospheric pressure only may be arranged in another arm of the Wheatstone bridge, thus obviating errors due to change in the atmospheric pressure. The indicating-instrument may be calibrated to give direct readings of the depth, and a permanent record may also be made thereby.

Protective arrangements; running generators in parallel; transmission conductor arrangements; switching systems; doubly-wound alternators, with.-The external reactance required in multiple generator systems to limit short-circuit currents, and to facilitate the parallel running of aud load distribution amongst the generators, is reduced or eliminated by employing synchronous generators having two armature windings connected to separate bus-bar. sections which are interconnected by the coupling effect of these windings, the reactance of the machines themselves safeguarding the system. Fig. 1 shows bus-bar sections 2 - - 7 with reactances 13 between sections 2 and 3, 4 and 5, 6 and 7. Switches 12 interconnect the bus-bar sections and switches 14 may short-circuit reactances 13 as required. To sections 3, 4 and 5, 6 the windings 16, 17 of two doubly-wound alternators 15 are respectively connected through external reactances 20, 22 and switches 21, 23. Thus the bus-bar sections 3, 4 and 5, 6 may be connected directly or only through the inductive action between the windings. The reactances 13 may be dispensed with. The switches 12 between stations 3, 4 and 5, 6 may be replaced by the switches 12, 12<1>, Fig. 3, in series. To enable transfer of power from busbar stations supplied by generators of the usual type a synchronizing bus-bar may be provided to which they may be connected through reactances, and switches may be arranged to connect the synchronizing bus-bar to a point between the switches 12, 12<1>.

The above difference is due to a surface tension effect and may be varied by varying the slope of the edge, Figs. 1 and 3, or by making a slope on two sides of the cup, Fig. 4. The above cups are stated to produce a difference of from 15 to 22À5 per cent of the operating voltage.

Abstract: 1294032 Lasers RCA CORPORATION 26 March 1970 [4 April 1969] 14829/70 Heading H1C In a gas discharge tube containing at least two inoizable gases, an optical element such as an end mirror or window is protected from ions by electrostatic forces. The forces are produced by the discharge electrodes, with or without additional electrodes. In Fig. 1, the tube 10 contains a vapour from a heated source 16, and a condenser 22 is provided. The source and condenser respectively contain the discharge anode and cathode, and additional electrodes 24, 30 are provided, each of which is positive with respect to the adjacent discharge electrode so as to repel positive vapour ions away from end windows 12 and 14. The tube may be operated with the power supply 32 connected only to a pair of electrodes such as 24 and 28, Fig. 2 (not shown), or 24 and 30, Fig. 3 (not shown), but in such cases only the window adjacent the anode is protected by the electrostatic forces, and the other window must be placed well away from the cathode. The power supply may have a reversing switch, while the vapour source may act as the condenser and vice versa, so that when all the vapour is in the condenser reversing the operation of the tube extends its life, Fig. 4 (not shown). A pressure equalizing tube, in which the vapour may condense, may be provided between the vapour source and condenser, Fig. 5 (not shown), so that condensed vapour returns to the source. An R.F. generator may be connected to the electrodes in place of the D.C. supply, Figs. 6, 7 (not shown), in which case the necessary D.C. electrostatic screen is provided by connecting diodes in series with some of the electrodes. The vapour may be cadmium or mercury, and helium may be added.

Also during the coupling rupturable members 36, 62 engage, the latter forcing the former on to piercing rib 30 so that both members are fractured, both members 36, 62 being folded back to occupy spaces between the mating parts of the pipe coupling bodies. The final seal is produced by a gasket 48 of triangular cross-section sprung into a recess 42 in the end of the first body member 10 and being of a harder material than that of the body member, the base apices of the gasket, i.e. in cross-section, cutting into the ends of the body member. The diaphragm may be of a soft metal, e.g. brass, and may be bonded into the body members by soldering, brazing or gluing with a plastics material.
