Title: Obtaining an upwardly propagating data signal in wellbore communication system
Inventor: CLARK BRIAN
IPC: E21B47/18
Filed: 2007-05-01
Abstract: A method and system for wellbore communications comprises obtaining signals representing pressure measurements over time from a first pressure sensor, a second pressure sensor, and a third pressure sensor positioned within a drilling system. The velocity of the signals in the wellbore fluid is determined based upon the maximum values for cross correlation functions between the respective pressure sensor signals. In order to determine a downwardly propagating noise signal the signals from the first, second, and third pressure sensors are time-shifted and stacked. The downwardly propagating noise signal is subtracted from the signal from the first, second, and third pressure sensors to obtain a first corrected pressure signal, a second corrected pressure signal, and a third corrected pressure signal. A cross-correlation function is computed between the corrected pressure signal and the downwardly propagating noise signal for first, second, and third corrected pressure signals. The standard deviation and reflection coefficient of the downwardly propagating noise signal is computed. The upwardly propagating noise signal is then subtracted from the corrected pressure signal for the first, second, and third sensors to obtain a twice corrected first pressure signal, a twice corrected second pressure signal, and a twice corrected third pressure signal. The twice corrected first pressure signal, the twice corrected second pressure signal, and the twice corrected third pressure signal are then time-shifted and stacked to obtain an upwardly propagating data signal.

Title: Improvements in or relating to thermionic amplifiers
IPC: H01J43/30
Filed: 1941-08-07
Abstract: 550,340. Converting. ELECTRICAL RESEARCH PRODUCTS, Inc. Aug. 7, 1941, No. 10037. Convention date, Aug. 15, 1940. [Class 38 (ii)] [Also in Group XL] In an amplifying circuit using arc electron multiplier having an input grid biased back so as to pass only small positive pulses of the modulated carrier input, and a grid having a steady positive bias, means are provided for varying at the modulations frequency, the average anode potential so that at the minimum voltage swing the anode potential is substantially equal to the positive grid potential. In Fig. 1 an electrode multiplier 1 comprises a cathode 7, input grid 8, accelerator 9, emitter plates 5, 6, 10 a positive grid 11 and an anode 12 feeding an output circuit 3, 4. A battery 16 provides negative bias for grid 8 so that only part of the positive half cycles of an input applied at 2 is transmitted. Cathode resistance 17 and condenser 18 are arranged so as to vary the grid bias at the modulation frequency and provide negative feed back at the same frequency. A negative feed back from the output to the input is provided by lead 51 including condensers 52 and a variable loss network 53. The emitters are arranged at suitable potentials by means of battery 13 and voltage divider 14. Grid 11 is more positive than the last emitter 10, and anode 12 is held at an average potential more positive than 11 by a lead 24 from the voltage supply which is taken through a choke 26 from the cathodes of six mercury vapour rectifiers 29 the anodes of which are connected individually to the windings of a six-phase secondary 30 fed by a three phase primary 31 connected to supply mains 32. The voltage applied to anode 12 is varied by means of two phase-shifting valves 33, 34 which vary the phase of the grid supply to tubes 29 through transformer 35 and limiting resistances 36. If the average anode potential is such that at the minimum voltage swing anode 12 is negative to grid 11, grid current flows and is applied through direct current amplifier 38 and switch 55 to alter the internal resistance of tubes 33, 34 to increase the anode potential which is thus kept at the most efficient value. A similar result may be obtained using the voltage across resistor 17 applied through an amplifier 381, switch 55 being placed in the alternative position. In a modification, Fig. 6 (not shown), the anode voltage is barred by means of a saturable choke in the anode supply lead. The Specification as open to inspection under Sect. 91 also describes the application of two electron multipliers in parallel, Fig. 7 (Cancelled) (not shown) arranged in the circuit described in Specification 471,423, [Group XL]. Also Fig. 8 (Cancelled) (not shown) there is disclosed an arrangement of a tetrode and a diode preceding the multiplier tube to give a degree of predistortion which will compensate for the non-linearity of the multiplier. This subject-matter does not appear in the Specification as accepted.

Filed: 1922-04-08
Abstract: 197,162. Hardie, Milroy, & Co., London, Ltd., and Milroy, A. April 8, 1922. Packing in air-tight chambers.-Relates to a method of and means for packing eggs in fluid form without the shells and consists in filling containers therewith in a vacuum, or filling them and then exhausting the air and sealing so that air is excluded. The eggs are forced on to hollow needles K, Fig. 2, in cups J in an extracting vessel A and the exposed ends broken by hand. An exhaust pump C, Fig. 1, is set in operation and valves A<2>, B<2> are opened and valves H, D<2>, G<3> are closed so that the egg is extracted from the shells and drawn into a distributor B. When the distributor is sufficiently full, the valves A<2>, B<2> are closed and the valves D<2>, G<3> are opened. A valve G<4> is opened to establish communication between a receptacle G and a casing F, and the valve H is opened to admit air to the top of the distributor. The egg is then drawn into communicating containers E, E<1>, E<2> and overflows through a conduit F<1> into a transparent receptacle G, indicating that the containers are filled. The valves D<2>, G' are closed and the casing F opened to the air by the valve G<4>, and the connections E<3>, E<4>, E<5> are sealed by pressure and severed. The sealed ends may be further secured by molten metal. If the containers E, E<1>, E<2> are strong enough to resist atmospheric pressure, the casing F may be omitted. In a modified method, the distributor is dispensed with and the egg fed to the containers by gravity at atmospheric pressure and the containers subsequently exhausted. Alternatively, the distributor may be placed at a height above the containers.
