Title: Equipment for Injecting Fluids into an Underground Formation
Inventor: APPELMAN TAMMO
IPC: E21B43/25
Filed: 1967-04-21
Abstract: 1,179,427. Wells &c. SHELL INTERNATIONALE RESEARCH MAATSGHAPPIJ N.V. 21 April, 1967, No. 18589/67. Heading E1F. Fluid injected into a well is directed into one of two formations 2, 4 of different resistances to injection and separated by an impermeable formation 3. The "soak process" of oil recovery is carried out in a well having opposite the formations a perforated liner 1 surrounded by gravel packing 7. Steam injected into the well through a tubing (not shown) passes mainly into the formation 2 having the smaller resistance, the well is closed in, and then oil from the formation 2 is produced through the tubing. A tubing 10, a packer 12, and a member 11 blanking off the perforations opposite the formation 3 are set in the well. Steam is injected into the formation 4 through the tubing 10, the well is closed in, and finally oil from the formation 4 is produced through the tubing 10. In modifications of the apparatus shown in Fig. 1, the member (13) blanks off the formations 2, 3, the tubing carries either a packer (15) or a labyrinth seal (21) each extending over the perforations opposite the formation 3, or the liner is not perforated opposite the formation 3. In the well shown in Fig. 6 the formation 24 having the smaller resistance is treated with steam and produced, the pipe 25, packer 27 and member 11 are set in the well, the formation 23 treated and produced. In modifications of the apparatus shown in Fig. 6, a member (28) blocks-off the formations 22, 24, a packer (29) extends over the perforations opposite the formation 22, the liner is without perforations at the formation 22, and a labyrinth seal (30) extending over the perforations opposite the formation 22 is supported on tubing (31) having perforations (32) above the seal. The invention may be applied to fracturing or acidizing, or to inject formations to increase hydrocarbon recovery.

Patent GB-188996-A (GB)
Abstract: 188,996. Western Electric Co., Ltd., (Western Electric Co., Inc.). Dec. 20, 1921. Automatic exchange systems.-In order to eliminate the detrimental effect of one or some particular number of interruptions of the line circuit due to the subscriber disturbing the switchhook before transmitting the selecting-impulses, one or more of the impulses in the first digit is suppressed, so that the switch is moved one or more steps by the accidental impulses, and then by the selecting-impulses through a number of steps less than the number of impulses. The invention is described as applied to the setting of a register-controller, indicated by the magnets 145, 164, and 184, and the contact arms shown above them. The registers are operated in succession under the control of switch 120, having contact arms 121 - - 124 and actuating magnet 125. Normal operation. When the register is taken into use, the relays 108, 109, 111, 116 are energized. The first set of impulses is repeated by relay 108 to the register magnet 145 and series relay 112, which, when the impulses cease, closes a circuit through its own winding, magnet 145, contact arm 144 (which has been moved two or more steps since the first digit is always greater than one), contact arms 163, 183, and relay 114. The magnet 145 and relay 112 do not energize owing to the resistance of relay 114, which closes the circuit of magnet 125, moving the control switch 120 one step to substitute register magnet 164 for magnet 145. The second register is then set, after which the relay 112 energizes magnet 125 to move the control switch a further step, the third and further registers being set in a similar manner. After the selection of the wanted line, the contact 118 closes restoring circuits through the magnets 184, 164, 145, 125 in succession. Operation when a preliminary impulse is sent accidentally by movement of switchhook. This is repeated by relay 108 to register magnet 145, which moves its arms 142, 144 on to contacts 146, 148, and after the impulse relay 112 closes a circuit for relay 113 over arm 142, but does not energize relay 114 as its circuit over contact 148 is opened by relay 116. The control switch thus remains in its normal position, but relay 113 remains energized. The first selecting-impulse is repeated by relay 108 over arm 123 to the righthand winding of relav 113 (instead of the magnet 145) and relay 112 which opens the circuit through the left-hand winding of relay 113. At the end of the impulse relay 113 de-energizes so that succeeding impulses pass to the magnet 145. By slightly modifying the circuits any desired number of preliminary impulses may be taken care of and an equal number of impulses suppressed from the first set of selecting-impulses.

Title: Improved process for bleaching vegetable substances by means of hypochlorous acid
IPC: D06L4/23
Filed: 1920-07-06
Abstract: In bleaching vegetable substances, the bleaching-liquid employed is a solution of free hypochlorous acid of about 0.01 per cent to 0.3 per cent concentration which is free from hypochlorites and is obtained by a substantially complete hydrolysis of chlorine, the water being in sufficient quantity for the reversible reaction Cl2+H2O\spHCl+HOCl to take place almost completely in the direction to the right.  The bleaching-liquid may be obtained by the introduction of chlorine in the presence of the material to be treated.  The hydrochloric acid produced by the hydrolysis of the chlorine and by the reduction of the hypochlorous acid during bleaching may be neutralized by reagents which do not combine with the weak hypochlorous acid, such as sodium or potassium bicarbonate, borax, sodium phosphate, sodium sulphate, chalk, limestone, zinc oxide or carbonate, barium or strontium carbonate, &c.  Reagents such as caustic soda or potash, burnt lime, baryta, strontium and alkali carbonates, which combine with both acids, may be employed provided they are sufficient only for combination with the hydrochloric acid.

Abstract: 1,082,975. Synchronizing. PLESSEY-UK Ltd. April 30, 1965 [May 7, 1964], No. 19090/64. Heading H2H. [Also in Division G1] An apparatus for the frequency and phase comparison of two periodic signals (a), (b) includes arrangements 12, 13 for producing two pulse trains, each corresponding in frequency and phase to one of the periodic input signals, the pulses of the trains having the same fixed duration, and a coincidence gate 14 to which the two pulse trains are applied and which supplies an output pulse to a scalar circuit 15 whenever a pulse in one train overlaps a pulse in the other train. The scalar circuit delivers an output pulse whenever it reaches the condition corresponding to its maximum stored count (three in the particular embodiment), but is reset to its zero count state by a reset pulse obtained from one of the input pulse trains through a second scalar 16 having a division factor one greater than the first, or output scalar. Thus output pulses are obtained from the apparatus only when input waveforms are in frequency and phase synchronism within limits defined by the reset pulses from the second scalar and by the width of pulses from the pulse shapers for at least a given number of successive cycles (three in the particular embodiment described). The output pulses, indicating frequency and phase synchronism, may be used to energize an indicator or to close a contactor for parallelling a pair of associated generators supplying the two input waveforms.
