Title: System for measuring components of a three-component gas-liquid flow of oil wells
Inventor: FURMAKOV EVGENY FEDOROVICH
IPC: E21B47/12
Filed: 2007-04-18
Abstract: The invention can be used in the oil-producing industry for controlling a well flow rate. The inventive system comprises three coaxially mounted high-frequency resonators, each of which is provided with two mutually orthogonal inputs-outputs, short-circuited limiting and short-circuited limiting-dividing coils, a pressure gauge, a temperature sensor, a computing-control unit, a controllable high-frequency generator, a controllable switch, a regime controller, delay units, input amplifiers and six receiving / transmitting paths, each of which comprises two coupling capacitors, an input amplifier and an analog-to-digital converter. The invention is based on a method for a high radio frequency sounding of a controllable flow in two mutually orthogonal directions, which makes it possible to measure the relative content of the components thereof, and uses a speed autocorrelatively measuring method for measuring the flow speed, thereby making it possible to componentwisely calculate the volume flow rate of a gas-liquid medium according to said measurement results. The flow regime of a gas-liquid medium, carried out by means of the controller, makes it possible to reliably determine the componentwise flow rate even at substantially unstable flow conditions and a method for mutually orthogonally sounding a controllable medium, used in the system, makes it possible to measure even at the totally stable flow of a homogeneous medium, when the controllable flow is devoid of local heterogeneities of a compositional analysis. When necessary, the system is able, by using information received from pressure and temperature sensors, to compute and transmit information about the componentwise mass-flow rate of a gas-liquid medium to external systems.

Title: Improvements in or relating to frequency responsive circuit arrangements
Inventor: AGAR WILLIAM OLIVER
IPC: G01S13/58
Filed: 1955-04-06
Abstract: 858,941. Frequency measurements. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Dec. 1, 1955 [April 6, 1955], No. 10085/55. Class 37 To measure the mean Doppler frequency produced by a moving radio reflecting object (in e.g. a band 0-10 kc/s), in the presence of noise signals of comparable amplitude, the signal is first raised to a value convenient for handling e.g. 210-220 kc/s by a frequency changer 2 and then passed through a second frequency changer 4 having a pair or cyclicly switched local oscillators 5, 6 operating above and below the "I.F." band. The oscillator 5 is fixed at e.g. 130 kc/s and the oscillator 6 is variable from e.g. 290-310 kc/s by a reactance valve 7. The output of the frequency changer 4 feeds a plurality of filters 9 having a band width of 20 c/s spaced 100 c/s apart in a band of e.g. 80-92 kc/s, and connected to a rotary-capacitor-sampling-switch 10 (revolving at e.g. 110c/s.). A sawtooth voltage is generated in synchronism with the sampling cycle by cam-operated contacts 12 discharging a capacitor 14 (so that the instantaneous amplitude of the saw-tooth voltage is characteristic of the filter being sampled). The output from the sampling switch is connected to a trigger-pair 20, 21 which operates, when the output from any of the filters exceeds the average output, to close an electronic switch 18, 19 to charge capacitor 17 to the instantaneous voltage across capacitor 14. This voltage, after amplification at 27, is cyclicly switched (in synchronism with the switching of the local oscillators 5, 6), to control the reactance valve tuning the oscillator 6; The system reaches a stable condition so that alternate connection of the oscillators 5, 6 produces no change in output frequency of the frequency-changer 4, and the sum of difference of the frequencies of oscillators 5, 6 is then a measure of the mean Doppler frequency. As shown oscillators 5, 6 are connected to a mixer 30 feeding a counter 31.

Abstract: 212,769. Barlow, H., and Muff, G. April 14, 1923. Clearing apparatus. -In a yarn clearing device of the kind comprising a disc provided with slits of different widths and a shield or guard plate designed to expose only one of the slits at a time, a guide wire f<2> sprung on the boss of the guard-plate b spans the slot b<1> in the guard-plate and serves to retain the yarn in the slit a<1> of the disc a that is opposite the slot. The edges of the slits are bevelled and their ends are of fish-tail formation. The slits may be marked to indicate the count of yarn for which they are suitable, and if desired one side of the disc may be marked for worsted and the other for cotton. To facilitate setting, the edge of the disc is notched on each side of the slits to register with the edges of the slot b<1>. A slit a<5> of greater width than any yarn to be dealt with is provided for use when a mild or no clearing action is desired. The Provisional Specification describes a wire guide, which is movable to allow of the insertion of the yarn.

Title: Improvements in or relating to process and apparatus for annealing glass sheets and plates produced by an intermittent rolling operation
IPC: C03B25/08
Filed: 1927-04-13
Abstract: 269,569. Soc. Anon. des Manufactures des Glaces et Produits Chimiques de St.-Gobain, Chauny, et Cirey. April 15, 1926, [Convention date]. Charges, conveying. - Relates to a leer for annealing plate or sheet glass which is produced intermittently in long strips. According to the invention, the strips are carried through the leer bv rollers which are in two groups driven at different speeds. The rollers R1 of the first group receive a strip F of glass from the rolling- apparatus and carry it forwards, at the relatively high speed of rolling, until the glass has set. The strip then passes on to the rollers R3 of the second group which convey it at a slower speed that allows the glass to be annealed by the time the strip leaves the leer. The number of rollers in each of the groups may be varied to suit the length of the glass strips and the speed of rolling. A series of rollers R2, free to rotate in their bearings, is arranged between the two groups of driven rollers and facilitates the passage of the sheet from the one group to the other.

Title: Improvements in impact clutches
IPC: B25B21/02
Filed: 1963-03-15
Abstract: 973,333. Overload slip couplings. ATLAS COPCO A.B. March 15, 1963 [April 2, 1962], No. 10309/63. Heading F2C. An overload slip coupling for power tools, &c. comprises a driving shaft 29, Fig. 1, having a rotary lost-motion spline coupling 52, Fig. 10, with a hammer mass 45 formed with an axial groove containing a rockable clutch dog 54, Fig. 7, which in the normal drive position is so tilted that its trailing edge 57 engages and transmits drive to one, 39, of two symmetrical camming ears 39, 40 constructed on an output anvil 25, 38. Radially projecting shanks 67, 68, Figs. 5, 10, on a spring 66 co-operate with a projection 64 on the driving shaft and an axial pin 62 on the clutch dog 54 to control the angular position of the clutch dog, angular movement of the driving shaft 29 relative to the hammer mass 45, as permitted by the lostmotion spline coupling 52, causing the clutch dog to tilt so that whichever of its two edges 57 is the leading edge is withdrawn into the hammer mass 45, Fig. 7. Since the parts are symmetrically arranged, the direction of rotation of the driving shaft 29 may be reversed. On overload of the anvil 38, the clutch dog 54 is tilted by the camming action of the engaged driven ear 39 on the anvil against the bias of the spring 66, and rides over the camming ear. The hammer mass 45 then rotates relatively to the anvil 38, Fig. 8, until the trailing edge 57 of the clutch dog 54 engages the camming ear 40 of the anvil, Fig. 9, and tilts the dog so that it rides over the ear. In this tilted position, the back face 55, Fig. 3, of the clutch dog 54 now gives a sharp blow with its leading edge to the front face 41 of the camming ear 39 on the driven anvil 38. During the rebound following the blow, the clutch dog 54 is tilted back by the spring 66 to the position shown in Fig. 7 and, if the overload has been surmounted, drive is recommenced. As shown, the shank of the spring 66 extends into a hole in the driving shaft 29, but alternatively it may extend into a hole in the driven anvil 25, 38. Reference has been directed by the Comptroller to Specification 934,010.
