Filed: 1972-05-04
Abstract: 1432335 Well-logging-digital computer applications SCHLUMBERGER Ltd 1 May 1973 [4 May 1972] 20846/72 Heading G4A [Also in Division G1] In the computer processing of well-log data, provision is made for interrupting immediate log computations and feeding the log-data to store, while a higher priority task is carried out. Any further instructions are queued. Interruptions are made notably by keyboard input and depth signals. For example the sonic log operates every ¢ inch while conductivity and magnetic logs operate every 6 inches, thus every 12th, ¢ inch programme will require also the 6 inch programme to follow. Fig. 1 which is substantially self-explanatory illustrates the computer facilities. A priority arbitration logic unit determines sharing of the common bus between the CPU and peripheral units, and the CPU operates with a core memory loaded as required (from tape inputs) with tables, and programmes for test, calibration and data processing. It is stated that the CPU may control the operation of the well-logging tool. One embodiment is described at length and with reference to flow diagrams Figs. 2 ... 50G (not shown).

Abstract: 877,129. Fluid-pressure braking systems. WESTINGHOUSE AIR BRAKE CO. June 15, 1960 [June 15, 1959], No. 20972/60. Class 103 (1). A control system requiring periodic actuation to prevent a control operation (e.g. braking) being effected automatically on a predetermined fall in pressure in a control pipe 1, comprises a lever 6 continually moved to an abnormal position to actuate a valve 3 to vent pipe 1 via restricted passage 54, 55, 56 and whistle 57, and a lock 4 for locking the lever 6 in the abnormal position until an acknowledgement valve 2 is temporarily released, the valve 4 also causing a fall in control pipe pressure when released. Normally a main reservoir 46, pipe 1 and brake pipe 45 are fully charged, and a cam 5 is rotating at a constant speed, a roller 29 of lock 4 abutting lever 6 and a mercury switch 33 energizing valve 3 to close valve 18; the pedal 7 is depressed to close valve 13. When cam lobe 36 rotates lever 6 a spring 26 projects roller 29 to lock the lever in an inclined position, the switch 33 de-energizing valve 3 to open valve 18 and vent pipe 1. The timing reservoir 51 maintaining sufficient pressure in pipe 1 to prevent initiation of braking for a given period. To prevent braking, pedal 7 is released to open valve 13 to pressurize chamber 25 from reservoir 51, the roller 29 being disengaged from lever 6 which is returned to its initial position; the switch 33 re-energizing valve 3 to close valve 18. The venting of pipe 1 via pipe 16, chokes 61, 63 and whistle 64 is stopped by depression of pedal 7 to close valve 13, chamber 25 then being vented via choke 52. Hence pipe 1 is vented via chokes 61, 52 whenever pedal 7 is released. Should the pressure in pipe 1 fall below the predetermined value and handle 44 is in the running position, then valve portion 49 reduces pressure in pipe 45 to apply the brakes, branch 1a of pipe 1 being connected to atmosphere via port 1b to ensure brake application even if the operator belatedly completes the acknowledging operation. To release the brakes, handle 44 is moved to lap position in which valve 43a closes port 1b, reservoir 46 charges pipe 1 via choke 48 and portion 49 is returned to its normal position wherein branch 1a is disconnected from port 1b; handle 44 is then moved to the running position to recharge brake pipe 45.
