Title: Improvements in apparatus for indicating or recording the level of a liquid
IPC: G01C13/00
Filed: 1926-10-12
Abstract: 281,817. Wollaston, H. J. Buchanan-. Oct. 12, 1926. Indicators actuated by pressure of head of liquid.-Apparatus for indicating liquid level or depth comprises a horizontal conduit which may be in the form of a coil, maintained charged with the liquid at one end, and with air at the other end which is connected to a pressure or vacuum gauge. A lamp 2, Fig. 1, is connected by a siphon 4 to one end of a pipe coil a arranged horizontally, and of such a bore that the liquid moves in it as a complete column. A pipe 5 containing air is connected to the other end of the coil a and to a similar coil b having a transparent indicating tube 3, or to an ordinary pressure gauge. The liquid fills only part of the tubes a and b. The indicator tube b may be at a distance, and if the liquid employed is the same as that in the tank, the height in the tube 3 will be the same as that of the liquid level 1 above the tube a. In a modification, the tube a may be above the tank, in which case the air pipe 5 is connected to the upper end of the tube 3, and a suction pump is employed. Any other indicating liquid may be employed in the tube 3. In another modification, Fig. 4, for indicating the draught of a ship, the horizontal pipe a is carried by a frame 10 which is supported in gimbals 11 to keep it horizontal. In another modification (Fig. 5, not shown) the liquid flows into the tube a by gravity. To avoid an inconvenient length of the tube 3, several horizontal pipes b and indicating tubes 3 may be connected in series by air pipes 5, the indications in all the tubes 3 being added together. Alternatively (Fig. 7, not shown) a constant positive or negative head may be superposed on the readings by a vertical column of liquid. Slight level variations far above or below the level of the tube a may thus be indicated on a sensitive instrument. In all the modifications, an air trap 17 may be provided to collect any air bubbles which may rise from the tube 4. Small liquid columns 'which may be formed in the tube a may pass through an extension 20, Fig. 4, into a liquid trap 21. In the application of the invention to a depth indicator (Fig. 8, not shown) the tube a is arranged above the liquid and a pipe carrying a collapsable bag is lowered into the liquid. The pipe contains liquid of a lower specific gravity, which passes through a branch of the dip pipe to the horizontal pipe coil, and its pressure is indicated as before. The apparatus may be applied to the indication of level in a petrol tank. Specification 249,653 is referred to.

Title: Improvements relating to pressure core takers
IPC: E21B25/08
Filed: 1950-10-19
Abstract: 693,379. Core drills. ANGLO-IRANIAN OIL CO., Ltd., and OTWAY, C. W. Oct. 2, 1951 [Oct. 19, 1950], No. 25460/50. Class 85 A core-taker, so designed that the captured core is brought to the surface at the same pressure as occurred at the bottom of the bore, comprises a core bit carrying outer barrel 10 secured to the drill rod, and fixedly positioned therein is a pressure retaining barrel 11 provided at the lower end thereof with a spring- biased flap valve 24 that can close the bore of said barrel 4 but which is held open by a core barrel 12 slidably located within said barrel. In the core drilling position, the core barrel 12 is held stationary, against the action or a spring 33, with respect to the barrel 11 by spring biased clawed arms 21 engaging a plate 28 mounted on an extension 26 of the barrel 12. When sufficient core has been drilled, the string is raised and the catchers 62 engage the core as the barrel 11 rises with respect to the barrel 12 as the latter is held stationary by the core so that the arms 21 on the barrel 11 disengage from the plate 28 of the barrel 12 with the result that the spring 33 now forces the barrel 12 upwards into the barrel 11 past the flap valve 34 which closes to retain said barrel 12 in a chamber at the pressure ocurring at the bottom of the bore, the barrel 11 being sealed at the upper portion by mutual engagement of shoulders 46, 45 on barrels 11, 12 on a packer ring 47. The three concentrically disposed barrels are now withdrawn to the top of the bore. If the core is soft so that the catchers do not lock therein, the arms 21 can be tripped by dropping a heavy weight down the bore on to the end of the core barrel to force it downwards, relative to the barrel 11, or the rate of pumping is increased, so that differential pressure occurs on adjustable flow resisting baffle plates 55, 56 secured to the upper end of the barrel 12. To maintain the pressure in the barrel 12 aproximately constant to that existing at the bottom of the bore during withdrawal of the tool compensating means are provided and consist of a chamber 54 leading to the core-receiving chamber of the barrel 12, the chamber 54 having therein a piston 48.' Before lowering the tool into the bore the chamber 54 is pressurized through needle valves 53, 52 to a pressure approximately equal to that existing at the bottom of the bore and the valve 53 closed. On the tool being brought to the surface the bit is removed from the drill barrel and spacer member 19 replaced by a plug and pump and the pressure in the core barrel maintained by pumping fluid past valve 34, whilst the pressure in the compensating chamber is reduced to atmospheric so that portions 11c and 12d can be removed to allow opening of the valve 51 and the reduction of pressure within the core barrel.

Filed: 1951-11-02
Abstract: 707,316. Vehicle lighting systems. SCINTEX. Nov. 2, 1951 [Nov. 3, 1950], No. 25746/51. Class 38 (4) Relates to an electrical system for a vehicle of the kind wherein a thermal switch automatically introduces resistance into a circuit in which a short-circuit has occurred and simultaneously completes another lighting circuit independent of the faulty circuit, so that some part of the lighting system of the vehicle is always available for use. The head lamps 25 are normally supplied from a source 1 over contacts 5, 6 of a bimetal switch 3, 7 and contact 24 of a manual switch 13. If a short-circuit occurs on the headlamp circuit or on the other equipment lines 10, 11, the excessive current flowing through the bimetal strip 7 causes it to flex in the direction of arrow F, thereby opening contacts 5, 6 (to insert resistance 14 in series with 'the fault) and allowing a contact 4, which is carried by a resilient strip 3, to engage a further contact 9 and thus complete a circuit to the dim lamps 27. The limited fault current traversing resistor 14 maintains strip 7 flexed, which is indicated by lamp 28. A similar bimetal switch 21, 17 is arranged in the normal supply circuit to the dim lamps (which includes contact 15 of switch 13) so that a fault on this circuit causes strip 21 to flex and place resistor 22 in series with the fault, whilst allowing contacts 19, 23 to close and complete a circuit to the headlamps. Switch 17, 21 is more sensitive than switch 3, 7, so that the latter is not operated.

Abstract: 803,686. Fluid pressure brakes. WESTINGHOUSE AIR BRAKE CO. Aug. 24, 1956 [Aug. 25, 1955], No. 25935/56. Class 103 (1). In order to accelerate the release of the fluid pressure brakes on a train and particularly the rear vehicles on a long freight train, an initial increase in the pressure in the brake pipe 4 is arranged to be transmitted by conduits 20 and 89 to chamber 88 of a direct release valve device 82. The diaphragm 83 is thus quickly flexed upwards so that, as shown in the Figure, chamber 86 and a storage volume 87 are isolated and a pipe 7 from the auxiliary reservoir 8 is placed in communication with chamber 62 in the main valve assembly. The service valve 70 is thus moved downwardly so that brake cylinder pressure may be released direct to atmosphere through opening 75, passage 77 and exhaust choke 78. The pressure in chamber 88 of the direct release valve 82 subsequently equalizes through check valve 105 and pipe 106 with the pressure in chamber 86 and volume 87. Thus, if during a brake release a partial application is made by a slight decrease in the brake pipe pressure, diaphragm 83 will quickly flex downwards and return the valve 90 to its cut-off position terminating the release of brake cylinder pressure to atmosphere. The action of the release valve device 82 upon the main valve assembly may be cancelled at any time by a cock 97 having one position for graduated and the other for direct release of the brakes.
