Patent GB-843474-A (GB)
Abstract: 843,474. Separating substances by electrophoresis. GRASSMAN, W., and HANNIG, K. Dec. 3, 1956 [Dec. 2, 1955], No. 36960/56. Class 41. In a process for electrophoretic separation, the mixture of substances to be separated is applied to a porous carrier impregnated with electrolytic solution, the carrier being coated by means of a stream of cool gas and/or by increasing the absorption of its heat radiation; liquid evaporating from the carrier being replaced by the supply of liquid in mist or vapour form. Apparatus for carrying out the process comprises means for blowing a stream of cool gas on to the surface of a porous carrier and/or heat absorbing means so disposed as in operation to absorb heat rays from the carrier and means adapted to supply a liquid mist or vapour to the carrier. As shown (Figs. 1a and lb), wherein Fig. 1b represents a section through the apparatus shown in Fig. 1a along the line A-B, an amino acid mixture to be separated is placed at the annode end in the form of a transverse based on a strip of filter paper 1 which is impregnated with acetic acid. Strip 1 is placed on mounting frame 2 so that both ends of the strip lie on the arms of the frame and sagging is prevented by the strip lying on nylon threads 3 transversely stretched between rollers 2a. Two filter cloths 4 embedded in dialyzer tubes are laid respectively on each end of the electrophoresis strip and are brought into electrical contact with the strip ends by compression between the frame 2 and frame 13. Chambers 5 and 6 contain buffer solution with which the filter cloths 4 surrounded by dialyzer tubes, come into contact. Chambers 8 and 9 contain buffer solution and are in contact with chambers 5 and 6 respectively by apertures 10 and 11 which are filled in with glass wool. Troughshaped recess 12 is either flushed with cooling brine or brine therein is cooled by cooling coil 12a containing refrigerant. A moist filter cloth 29 which can re-absorb liquid from supply tanks 14 is stretched across the electrophoretic strip by frame 13. The chamber is covered with electrically heatable glass plate 15. A direct current voltage is applied to electrodes 16, 17. Figs. 3a, 3b and 3c, (wherein Fig. 3c represents a sectional side elevation of the apparatus shown in plan in Fig. 3a, and Fig. 3b represents an electrophoretic strip used in the apparatus) shows a further embodiment wherein a frame 18 is provided with electrodes 19 and a filter paper 21 impregnated with electrolyte is placed so the current contact is made via a dialyzer membrane 22. The sheet 21 is traversed from top to bottom by electrolyte solution from supply trough 23. A cooled stream of air is conducted across the front of sheet 21. The mixture to be separated is conducted in a continuous flow e.g. by a closing device past the position shown at 26. Upon application of a voltage to its electrodes, its separated components drop from the dropper points 28 into a collecting vessel. Specification 679,278 is referred to.

Title: Overvoltage protection arrangements
Inventor: PHILLIPS JOHN PETER
IPC: H02H9/04
Filed: 1986-03-06
Abstract: An overvoltage protection arrangement for protecting an electrical line and presenting a high shunt impedance and low shunt capacitance to signals normally carried by the line, comprises a gas discharge tube G connected in shunt with the lines L1, L2 to be protected and a non-linear solid state clamping device D1, D2 connected across the gas discharge device. Both the clamp voltage of the solid state device and the D.C. sparkover voltage of the gas discharge tube are chosen to be greater than the peak signal voltage to be normally carried by the line and the clamp voltage is greater than said D.C. sparkover voltage. A heat responsive protection device F1, F2 which is responsive to overheating of the gas discharge tube is connected so as to provide a short circuit path across the gas discharge tube in the event of it becoming overheated. The clamping device may be a voltage dependent resistor, a zener diode, or a foldback diode (DFB), (Figure 5b). A resistor (R) may be connected in series with such a foldback diode at least partially to compensate for the negative resistance characteristic of the diode. The heat responsive device may be a fusible link or a shorting wire covered with a fusible insulating material. <IMAGE>

Title: Apparatus and method for removal of accumulated liquids in hydrocarbon producing wells
Inventor: AMANI MAHMOOD
IPC: E21B34/10
Filed: 1988-09-09
Abstract: A method and apparatus are disclosed to detect periodic well loading by produced accumulated secondary fluids, and accordingly to remove the undesired secondary fluids from the tubing of a hydrocarbon producing well. The method according to the present invention employs a surface control system (108) that controls the operation of the fluid removal cycle, and the production cycle. Periodically, the well is "shut-in" and upper (70) and lower (120) flow control valves are actuated to a closed position to form an accumulation chamber (104B) within the tubing. A supply line (107) is used to inject pressurized gas into the accumulation chamber (104B) to force the secondary fluids into the annulus (130) of the well and thereby remove the undesired secondary fluids from the tubing. The flow control valves (70, 120) are then opened and the producing well is returned to production. A specific control valve (70) is also disclosed.
