Title: Control unit for pin hole detectors
IPC: G01N21/894
Filed: 1949-10-06
Abstract: 662,612. Photo-electric pin-hole detectors. CARNEGIE-ILLINOIS STEEL CORPORATION. Oct. 6, 1949 [June 1, 1949], No. 25693/49. Class 40 (iii). In a photo-electric pin-hole detector for metal sheets the cell triggers a thyratron which controls a delay device to deflect defective sheets when they reach a particular position. As shown, the strip is fed from a roll 2 through side trimming wheels 4, between a high intensity light source 22 and a bank of photo-cells 24 through measuring rolls 6, shearing drums 8 which cut the metal into strips, and over a conveyer 10. If the photo-cells 24 responded to a pin-hole in the metal a deflector 12 is operated by a solenoid 14 and a delay device 34 so that the sheet is directed into a bin 16. If the deflector is not operated the sheets pass over a conveyer 18 to a bin 20. The pin-hole detector may be of the type shown in U.S.A. Specification 2,229,638 and the delay mechanism as described in U.S.A. Specification 2,217,342. Circuit details.-Upon receipt of a light impulse from a pin-hole in the sheet, photo-cells 24 operate through amplifier 26 to trigger a thyratron 38 whose grid is normally biassed negatively. This thyratron closes an anode relay 54 which feeds a triggering pulse to a second thyratron 40 and operates an A.C.-fed relay 52 to break the anode circuit of thyratron 38. Thyratron 40 now operates relay 68 to supply alternating current to a solenoid 32 which marks the defective plate and the timer 34, which closes the actuating solenoid circuit of deflector 12 when the plate reaches it. Relay 68 also removes a short-circuit from a condenser 70 which commences to charge through variable resistor 72. The potential developed across the condenser is applied to the grid of an A.C. feed thyratron 42, which is thus triggered after an appropriate time delay breaking the anode circut of thyratron 40 by means of a relay 66. Should a second pin-hole be detected while thyratron 40 is still conducting, this pulse is fed through a condenser 80 to trigger a fourth thyratron 44 which discharges condenser 70 connected across its anode and cathode and cuts itself off. Condenser 70 then commences to recharge, thereby ensuring that the supply is maintained to timer 24 until the second defective plate arrives at the deflector.

Abstract: 982,282. Wells &c. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. July 1, 1963 [July 2, 1962], No. 26085/63. Heading E1F. Hydrocarbons are recovered from an underground formation by injecting steam into the formation through a well and producing hydrocarbons from another well, by stopping the injection before all the hydrocarbons which can be produced have been recovered from the formation, and reducing the partial vapour pressure of the steam in the formation. The reduction of pressure causes water present in the formation to evaporate. The pressure is reduced by injecting natural gas, air, combustion gas, or L.P.G. into the formation and this may be followed by water if the temperature of the formation has not reduced to that of the injected gas after the water in the formation has evaporated. Wells 13-16 are connected to line 17, 18, 19 respectively connected to a steam source, a gas source, and a storage tank, flow to and from the wells being controlled by valves 23, 24, 29, 30, 31, 29<SP>1</SP>, 30<SP>1</SP>, 31<SP>1</SP>, 29<SP>11</SP>, 30<SP>11</SP>, 31<SP>11</SP>. The valves 23, 31 are opened and steam is injected into the formation 10 through the well 13 whilst the hydrocarbons present between the wells 13, 14 are produced through the well 14 and stored in the tank. After the hydrocarbons present between the wells 13, 14 have been recovered the valves 23, 31 are closed and the valves 24, 29, 31<SP>1</SP> are opened so that gas and steam enter the formation through the wells 13, 14 respectively and the hydrocarbons are produced through the well 15. After the hydrocarbons present between the wells 14, 15 have been recovered the open valves are closed and the valves 30, 29<SP>1</SP>, 31<SP>11</SP> are open to permit production from the well 16 in a similar manner. In a modification the gas and steam are injected into the formation through one well and the oil produced through another well.
