Title: System for positioning a submerged displaceable element
Inventor: HARBONN JACQUES
IPC: E21B43/01
Filed: 1969-02-14
Abstract: 1,260,393. Position finding. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 14 Feb., 1969 [14 Feb., 1968], No. 8253/69. Heading H4D. [Also in Division G3]  A displaceable element which can be lowered from a surface craft is positioned relative to an underwater structure by finding the position coordinates of the craft relative to a fixed system of beaconing units, using a dynamic anchoring system to bring the craft position into plumb with the structure, and actuating a device on the element for laterally displacing the element to align a coupling part of the element with a complementary coupling part of the underwater structure. In the embodiment shown, the element is a duct 23 for draining degasified crude oil from underwater storage tanks 1 to 6. Craft 14 position is determined (e.g. as in Specification 1,162,714, Division H4) from the relative times of receipt at hydrophones H1 to H4 of an acoustic signal from transmitter transducer 21, the hydrophones being coupled to radio buoys B1 to B4. The craft is then held on station, by thrusters 15, 16, over a selected tank while duct 23 is unreeled. A motor-driven transmitting/ receiving transducer system in the lower end 25 of duct 23 provides a directional sonar beam rotating in a horizontal plane for finding the position of end 25 relative to reflectors or responders R1 to R3, the sonar echoes being displayed on a craft-borne cathode ray tube plan position indicator whose angular sweep is synchronized with the transducer rotation by means of a servo, e.g. a selsyn. The end 25 is then displaced laterally by one or more fluidpressure jets with valves controlled remotely from the craft 14. The valves may ba servocontrolled in accordance with the sonar data, to align automatically end 25 with a drainage valve 13 in the storage tank. End 25 is then lowered further to sealingly enter the valve 13 and to open the valve so that an electrically or hydraulically powered, pump in end 25 can transfer the oil to craft 14. Raising duct 23 closes valve 13, which is biased to close against any hydrostatic pressure differential. Duct 23 may also be used to raise a faulty item of equipment. Conductors for the electrical apparatus in the end 25 may be incorporated in duct 23. Instead of the sonar system for locating the end 25 relative to the underwater tank, one or more television cameras and monitors may be used.

Title: Braking methods and apparatus
IPC: B23Q15/26
Filed: 1972-02-23
Abstract: 1388574 Control of electric motors XEROX CORP 23 Feb 1972 [25 Feb 1971] 8288/72 Heading H2J [Also in Division F2] A rotating device 104, such as the drum of a facsimile transceiver, is stopped at a desired angular position, following the termination of one of a pair of monitoring signals A, B, by control of the A.C. or D.C. motor 103 driving the device 104 at a constant angular velocity, the motor being subjected to hysteresis (eddy current) braking for a period of time determined by the field strength, angular velocity and inertia of the motor whereby it is brought to a stop at the desired position. Although mention is made of the drive means 102 applying D.C. to the motor 103 in accordance with the regulated signal supplied from a control means 101, the described embodiment uses a synchronous motor 103 supplied with a rotating field by a conventional push-pull amplifier 102 providing a two-phase supply. Members 101, 102 are controlled by a circuit including AND and OR gates, inverters and two monostable multivibrators 107, 108 connected as shown and responsive to the signals A, B and a periodic signal produced by a sensor 105 each time the device 104 passes a given angular position, the latter signal initiating signal interchange between various gates and operation of the multivibrators to constitute a periodically-occurring operation which, if both signals A and B are present, prevents the production of an output signal from AND gate 110. If one of these signals terminates however, the gate 110 produces a braking signal for a time equal to the difference between the delay times T 1 , T 2  of the multivibrators 107, 108, the braking signal commencing at the end of time T 1  of multivibrator 107 and terminating at the end of time T 2  of multivibrator 108 and both times commencing with the periodic signal produced by sensor 105. The signal from gate 110 is applied to control input 101a of the drive means 102 to interrupt one phase of the two phase supply and so produce hysteresis braking for the period of time T 2 -T 1  chosen in accordance with the parameters mentioned above, whereby the motor stops at the end of this period in the desired position. Resetting of multivibrator 108 and the continued absence of the signal A or B then ensure that gate 116 or 117 controls member 101 to cause drive means 102 to de-energize the motor. Various operating cycles of the circuit are explained, Figs. 2A, 2B and 2C (not shown), for termination of either signal A or B or momentary loss of signal A, hysteresis braking being prevented for the latter condition and delayed until the next operating cycle if the termination occurs after the device 104 has passed a predetermined angular position corresponding to the time T 1 . The latter position may be detected by a further sensor, in which case the multivibrator 107 can be omitted.
