Filed: 1920-06-24
Abstract: 169,290. Vedder, D. G. June 24, 1920. Wells.-Water is shut out of oil and like wells by freezing the water in the area between the water-bearing stratum and the oil &c. bearing stratum and externally of the well casing. After sinking the well it is filled with mud and a casing 46 is lowered therein, the casing having a perforated lower end within which is a short perforated casing 52; the inner casing, is secured at its upper end to the outer casing by a bellshaped fitting 50 and between the casings is a cement &c. barrier 48. A plug 60 of wood, rubber, cement, &c. is then lowered and driven into the inner casing 52 and the mud above the plug is removed. An inner casing 49 is then lowered and connected by threading to the first inner casing 52 ; a freezing-coil 53 is also lowered. A non-freezing solution, such as calcium-chloride solution, is poured in between the casings 49, 46, and the coil 53 is connected to a refrigerating plant 54; the mud outside the casing 46, between the water zone 43 and oil zone 45 is then frozen. The plug 60 is then drilled out and pump tubing is lowered within the inner casing, a plug near the foot of the pump tubing keeping the space between the pump tubing and inner casing free from oil, so leaving an air jacket which prevents freezing of the oil in the pump tubing, or a vacuum may be formed in this space and also above the non-freezing solution. The freezing-process is continued during pumping. The outer casing 46 may be lowered during the drilling of the well; then after completion of the drilling, the short inner casing 52, with its plug 60, bell fitting 50, and an annular external plate above its perforations, is lowered into position and cement is forced through a, pipe penetrating the fitting 50 to form the barrier 48 above the annular external plate. The mud above the barrier is then removed, and the casing 49 &c. applied as before. A frozen shut-off device may also be employed where a water zone is found below an oil zone or between two oil zones.

Filed: 1962-05-04
Abstract: A liquid hydrocarbon, e.g. bunker C oil, is coked in a zone 4 and part of the coke is transferred (via 5 . . . 7) to a gasification zone 3 where it is contacted by a gas containing free oxygen (e.g. air) at a temperature of 1700 DEG  to <PICT:0998880/C4-C5/1> 2200 DEG F., the carbon/oxygen ratio of the feed to the zone 3 being controlled so that at least part of the coke is consumed, coke particles being supplied to the zone 3 at a rate to maintain a supply of coke therein.  The zone 3 is preferably a fluidized bed, and the zone 4, to which an oxygen-containing gas may be delivered, may comprise a fluidized bed of coke introduced at 19. Preferred temperatures in the zone 3 are 1750 DEG  to 2100 DEG  F., and the pressure may be up to 40 p.s.i.g.  The oil for the zone 4 and the air for zone 3 may be preheated, e.g. to 200 DEG  to 650 DEG  F. and 400 DEG  to 1000 DEG  F. respectively.  The gaseous products, which mix in the space above the zones, are mainly hydrogen from zone 4 and CO from zone 3.  In a modification, see Fig. 2 (not shown), the zones are in separate vessels, and liquid hydrocarbon may be additionally delivered to the gasification zone, along with some or all of the gases from the coking zone, in order to control the H2/CO ratio in the final gas.  The coke introduced at 19 may be activated or petroleum coke.  Two detailed examples of the gasification step and details of the operating conditions (including C/O2 mole ratios of 0.5 to 1.5 in the feed), of the apparatus of Fig. 1, are given.

Abstract: 840,221. Radio navigation; radar; cathoderay tube circuits. STANDARD TELEPHONES & CABLES Ltd. May 30, 1958 [May 31, 1957], No. 17359/57. Class 40 (7). Line and frame deflecting arrangements of a cathode-ray tube produce a raster which is marked under the control of bearing-representing signals to give a linear locus whose direction indicates the bearing of a moving object relative to a fixed station. A central station " fixes " a mobile transmitter by receiving D.F. voltages x, y, proportional to the sine and cosine respectively of true bearing angles from spaced D.F. stations, and marking corresponding bearing lines from points representing the D.F. station positions. Sources 18, 19, Fig. 3, provide D.C. voltages E Œ y, E Œ x, where E is a constant voltage greater, for example, than the maximum value of 1x1 or 1yl. Frame sawtooth waves adjustably biased by potentiometer 36 are gated between voltages E and the more positive of EŒy voltages to produce " Y2 " pulses on lead 40 of duration t proportional to 1y1, Fig. 4, A and C; the " Y2 " pulses gate line sawtooth waves in "X wave " generator 39, Fig. 4, D (not shown). Gate 26 produces a " Y1 " pulse of duration t time-displaced from the " Y2 " pulse according to biasing potentiometer 28 setting. Fig. 4, H and J. The sawtooth " X " wave from generator 39, of duration t and of voltage rising from E to E+x, is applied to coincidence circuit 43 together with the "Y1 " pulse to generate short positive beam intensitymodulating pulses at their intersections, Figs. 4K, 4L. The end of a trace so marked is set to the D.F. station latitude and longitude by potentiometers 28, 45 respectively. Duplicate circuits are connected to points 49-53 for production of bearing markers of other D.F. stations. Picture signals received from a television-type ttansmission of a distant radar plan-position display may be inserted at point 53, the television synchronizing pulses controlling time-base generator 11 conventionally; a map or grid may be marked electronically on the tube screen by appropriate video pulse insertion at point 53. The "X" wave is generated by the charging (or discharging) of a capacitor during the " Y1 " pulse period, the capacitor value being electronically adjusted to be proportional to t in order that the " X " wave should terminate at potential E+x at the end of the " Y1 " pulse, Fig. 5 (not shown). In a modification interlaced scanning is provided, the bearing line being marked during one of a pair of frame sawtooth waves and the " X " wave being generated from a picture sawtooth wave having double the frame sawtooth wave amplitude and period, Figs. 8-14 (not shown). To adjustably " twist " the D.F. voltages for compensation of meridian convergency a resistor network is provided, Figs. 6, 7 (not shown). Electromagnetic cathode-ray tube beam deflexion may be used.

Title: Improvements relating to regulating systems for dynamo-electric machines
Inventor: SHAW NORMAN HARRY
IPC: H02P9/32
Filed: 1954-06-16
Abstract: 780,009. Automatic voltage control systems. ENGLISH ELECTRIC CO., Ltd. June 10, 1955 [June 16, 1954], No. 17726/54. Class 38(4). In an automatic voltage control system for an alternator, overriding automatic control means prevent reduction of the alternator excitation below a value determined solely by the magnitude of the alternator load current. As shown, a three-phase alternator G supplies bus-bars S and a direct voltage representative of average line voltage is derived through transformers T2, T3 and rectifiers DR1 and applied to a balancing circuit in which constant current is circulated by a D.C. source IR. The balancing circuit is arranged so that if the average alternator voltage deviates from a desired value determined by the setting of a rheostat VR1 an output is applied to a magnetic amplifier MA1 which energizes the buck or boost field winding Eef or Ecf2 of an alternator exciter E to the extent required to automatically restore the alternator voltage to the desired value. A voltage dependent on alternator excitation is derived from a resistor R3 and applied to a magnetic amplifier MA2 which injects a voltage through a rectifier DR2 into the balancing circuit when a lower limit of alternator excitation is reached so that excitation is raised and instability avoided. This lower limit of excitation is raised with increase of alternator load current by applying to magnetic amplifier MA2 a rectified voltage derived from an alternator load current transformer IT.

Abstract: 819,136. Testing and calibrating meters. LANDIS & GYR A.G. June 21, 1955 [June 23, 1954], No. 17968/55. Class 37. [Also in Groups XL (b) and XL (c)] In a system for testing and calibrating electricity meters against a standard meter, each meter, with the aid of a photo-cell, produces impulses having a recurrence frequency depending on the speed of its rotor and one set of impulses controls the rectilinear or circular time base of a C.R.O. and the other deflects or modulates the beam. Rectilinear trace, Fig. 1. In this system impulses from photo-cell F1 after amplification are applied to the deflector plates P1. Impulses from F2 discharge, with the aid of a gas filled triode V5, a capacitor C18 which between impulses is charged via a constant current pentode V6 to provide the horizontal sweep. voltage. To compensate for the fact that the voltage reached between discharge impulses depends on the speed, the bias on pentode V6 is automatically adjusted to resist any change in the maximum voltage at point 1. Changes at this point are transferred via the cathode follower triode section of valve V7 to the diode section which at a given voltage begins to conduct, discharging capacitor C19. The resulting change in the charging current of C19 modifies the bias of V6 appropriately. System with circular trace, Fig. 2. In this case the impulses from cell F1 control the beam intensity. Impulses from the other cell produce with the aid of an R.C. network quadrature alternating voltages which are applied to the deflector plates to produce a circular trace. Phase splitting network, Fig. 2. It is stated that if R1.C1=R2.C2=R3.C3 and R1: R2: R3 =1:6:3 and if R4.C4=R5.C5=R6.C6 and R4 : R5 : R6=1: 6: 3 then the phase difference between the voltages at A and B is independent of frequency and is proportional to loge R1.C1/R4.C4.
