Filed: 1928-05-21
Abstract: 310,211. Hardy, H. May 21, 1928. Cistern supply valves.-A cistern supply valve for use in a flushing cistern is actuated by a bottomless float surrounding the siphon bell acting through an arm or arms to operate a valve arranged to co-operate with a seat formed on the lower end of a downwardly extending inflow pipe. In the form shown in the Figure, the float 1 is formed integrally with the siphon bell 12 which has a pin 11 adapted to engage an arm 9 pivoted at 10 and connected by a pair of adjustable links 8 to a perforated cap 6. The cap 6, which slides on the inlet pipe 3, carries the valve washer 4. A regulating-screw is fitted at 14. The siphon bell slides in a dish 23 provided with inflow passages formed by depressing parts 24, and is operated by a lever 25 controlled by a spring 36. The bell has a pillar 27 guided by rollers 38. The pillar may be guided by the tank cover, and the actuating-lever may be operated by a spring-controlled sliding member. The tank 20, as well as the bells 1 and 12, may be made of sheet metal.

Title: Frequency conversion system
IPC: G01S13/02
Filed: 1945-06-15
Abstract: 595,224. Frequency converting systems. HAZELTINE CORPORATION. June 15, 1945, No. 15337. Convention date, Aug. 16, 1944. [Class 40 (v)] In a frequency converting circuit a primary pulse train is combined with a control voltage of lower periodicity so that only a limited group of primary pulses, with the periodicity of the control voltage, are translated to pulse responsive means which respond to one of the selected pulses to produce another pulse and thereafter remain unresponsive to the other pulses of the group. The Figure shows an application to a radar identification system. Primary synchronizing pulses from a radar system 10 pass through trigger valve circuit 30 and differentiating network 31, 32 to the control grid of a gating valve 27 biassed positively on the cathode through resistors 35, 36. A full-wave rectifier 23-26 develops an unsmoothed control voltage across resistor 22 which is applied to the screen grid 33 to allow a limited group of pulses to pass to biassed multi-vibrator 38 on each peak of control voltage. The first pulse of appreciable amplitude triggers multi-vibrator 38 producing a square wave form of width equal to the separation of the primary pulses and with the same average periodicity as the control voltage, so that the circuit is insensitive to further pulses of the group. This square wave-form reacts on screen grid 44 allowing valve 40 to conduct for the duration of the next primary pulse reaching the control grid and the output therefore consists of synchronizing pulses coincident with a primary pulse and with the same shape and having an average periodicity equal to that of the control voltage. The pulses from valve 40 trigger an identification system which receives echoes P', P" from a transpondor for display in opposite sense to echoes P from radar system 10. Switch 15 alternately connects system 14 to aerials 16 and 17 at half the frequency of the identification synchronizing pulses which also trigger multivibrator 20 to provide quenching pulses for system 10 and produce a horizontal shift on the horizontal scan generator 9 during every alternate quenching period in order to separate responses P', P" from the two aerials. Specification 479,935 is referred to.

Flow could be reversed so that 34 is the inlet and 24 the outlet. Baffles 21, 22 and 32, 33 extend below the water level to confine floating oil to the tank, an overflow pipe 28 delivering such oil into a chamber (29). Fig. 2 (not shown) illustrates two tanks separated by a wall (12) and acting in parallel. Solids accumulating on floor 17 are removed by a suction pipe (not shown). The separator plates are of rigid P.V.C. and mounted in a frame by means of blocks (Fig. 5 not shown) at their ends engaging in the channels (52, 53). The channels may be vertical or perpendicular to the plates or at some intermediate angle, and the upper channels (52) extend through holes (54) in the uppermost plate which extends beyond the others. The flat tops of the weirs are 17-25 cms long in the direction of flow, which ensures laminar flow across them and through separator 25. Dimensions and flow rates are exemplified.

Abstract: 1,135,879. Gas turbine engines. GENERAL ELECTRIC CO. April 5, 1967 [Aug. 24, 1966], No. 15519/67. Headings F1G and FIT. In an axial flow rotary machine, such as the turbine of a gas turbine engine, the stator assembly comprises a segmented ring of blade support platforms, there being at least one blade mounted on each platform and formed with a cooling fluid passageway therein. Each of the platforms includes a chamber having an inlet for receiving cooling fluid and an outlet connected to the passageway in the associated blade. A wall member is provided between the segmented ring and an annular manifold from which cooling fluid passes to the closed chambers of the ring, the wall member serving to restrict leakage of cooling fluid from the manifold through gaps between adjacent blade support platforms, there being a conduit which passes through the wall member to the inlet of each chamber for supplying cooling fluid directly from the manifold to the chamber, the conduits being so disposed as to allow thermal expansion of the stator assembly. In the embodiment shown the invention is applied to the second stage nozzle guide vanes 19 of the gas turbine of a gas turbine engine, the turbine assembly comprising rotor discs 11, 12 carrying rotor blades 10, 13 respectively. The inlet nozzle assembly comprises guide vanes 18 and the second stage nozzle assembly comprises guide vanes 19. The turbine stator casing comprises outer wall members 4, the upstream wall member being formed with inner and radial portions 20 so as to define an annular manifold 14 to which cooling fluid such as air tapped from the engine compressor is supplied through duct 16. The second stage nozzle guide vane assembly comprises vanes 19 mounted on arcuate support members 24 as shown in Fig. 2, the support members comprising walls 17, 26, 27, 28 which together define chambers 29 to which cooling air passes from the manifold 14 through ducts 30 and from which it passes to cooling passages 40 in the vanes 19 through bores 39, the air finally discharging through outlets 42 at the trailing edges of the vanes. The duct 30 is a close fit in the upstream wall 27 of the chamber 29 but is a loose fit in the radial wall 20 of the manifold 14, there being a clearance 44 between the duct and the wall. Some cooling air passes through the clearance 44 to the space 38, the air finally passing into the working fluid passage through the gaps between the ends of adjacent vane support segments. The radial wall 20 serves to prevent excessive flow of cooling air to the space 38 and so to the working fluid passage. Each vane support segment may support a single vane only. The duct 30 may be mounted in the bore in the radial wall 27 in such a manner that pivotal movement of the duct may occur.

Abstract: 722,788. Measuring gas pressure electrically. SIEMENS & HALSKE AKT.-GES. June 5, 1953 [June 5, 1952], No. 15610/53. Class 37. Apparatus for measuring low pressures with a cold cathode ionization gauge comprises means for noting the voltage at a predetermined automatically controlled value of the ionization current. As shown (Fig. 3), a valve 9 is placed in the discharge circuit of the gauge 2, the valve bias being obtained from across a series resistor 11 in conjunction with a battery 13, so that an increase in ionization current increases the bias on the tube to reduce the anode current to the desired value, and vice versa. The voltage across the gauge 2 is determined by measuring the voltage across the gauge and series resistor 11, with a further resistor 12 compensating for the drop across resistor 11. A parallel resistor 14 adjusts the reading on voltmeter 8 to zero for a given pressure. A half-wave rectifier may be connected across the meter 8 to modify the meter scale.
