Title: Improvements in or relating to control means for drilling devices
Inventor: RUSSELL MICHAEL KING
IPC: E21B7/06
Filed: 1969-04-08
Abstract: 1,268,938. Earth drills. M. K. RUSSELL. 7 April, 1970 [8 April, 1969], No. 17868/69. Heading E1F. [Also in Division G3]  An earth drill has a servo 3 for changing the drilling angle α and a servo 6 for changing the orientation of the drill. The drill is driven by a down-the-hole motor 8 preferably driven by drilling fluid, and electrical or hydraulic power for the servos is generated by power offtake from the drill motor, or by a separate motor. The angle servo 3 may be preset manually, or may be controlled by a programmer; the servo may have only two positions, for example α=0 and α=2‹. The measuring device 5 measures components of the earth's gravitational and magnetic fields, preferably about three body axes, for controlling the angular position of the servo 6, and for on-off control of the servo 3. The servos may be controlled by a programme carrier 11, which is lowered down the drill pipe to engage a receiver at the end of the control unit. A mule-shoe (12) and pin (13) locate the carrier at a predetermined angular position on the receiver, and adjustable bar magnets on the carrier are preset as references for the control system. The carrier may be retrieved by sending a fishing tool down the drill pipe, and the settings of the magnets changed.

Title: Electronic chord selection device for a musical instrument
Inventor: FREEMAN ALFRED BOYD
IPC: G10H1/38
Filed: 1970-04-15
Abstract: 1,274,801. Chord selection device. A. B. FREEMAN. 15 April, 1970 [23 April, 1969], No. 17970/70. Heading G5J. Any one driver 10 feeds an input to keyers 12, 13, 14 corresponding to the root, fifth, major and minor thirds, and seventh of the note operated, and either the major, or minor third, and possibly the seventh are inhibited from operating, so that minor or major chords, with or without the seventh are sounded. With the mode switch 26 in the position shown, operation of the drivers 10 gives rise to 6 major, and 6 minor chords, and the selector switch 16 may be used to give 3 distinct groups of 6 major and 6 minor chords. For positions 2 and 3 of the mode switch 26, all the chords are major, or minor respectively. For any setting of switches 26 and 16, the alternate musical key switch 24, which may be foot operated, interchanges the major or minor character of all chords. The drivers 10 may be interlocked so that only one at a time can be operated. The seventh of the chords is switched in or out by switch 29, and the thirds are selected via selector control 25, which is sensitive to signals from one or other of busses 17 or 18, depending on whether or not a voltage input is received from mode switch 26. Signals from keyers 14, corresponding to the root and fifth are fed via clamping diodes 35, 36 to a frequency dividing network 34 and are alternately clamped at a rhythm frequency by auto rhythm device 38 and RF control 37, so that root and fifth are sounded alternately at the output. Signals on leads 22 and 23 ensure that the root is sounded first when any driver 10 is pressed. A percussion envelope may be provided for the bass notes direct from auto rhythm device 38, which may also provide a rhythmic envelope to modulator 27, and tone shaping may be provided in the output circuit. A possible circuit for each keyer is shown in Fig. 2 (not shown), using clamping diodes to inhibit unwanted tones. In an alternative embodiment, Figs. 3, 4 (not shown) each keyer (51) receives signals from all drivers for which its tone may be required, Fig. 4 (not shown), and by earthing any of busses (56), (57) for thirds, or (58) for sevenths, the corresponding tone may be inhibited. With the mode switch (26) as shown, three sets of chords are selected by switches (59), (60), six chords being major, six minor, and operation of switch (26) gives rise to all chords being major. All major and minor chords may be interchanged by operating selector (25). The generator (68) may generate frequencies in several octaves.

Title: Hydraulic system for testing the operation of overspeed monitors
IPC: F01D21/20
Filed: 1967-04-19
Abstract: 1,128,573. Testing hydraulic circuits. STALLAVAL TURBIN, A.B. April 19, 1967 [July 14, 1966], No. 18004/67. Heading F1P. In an hydraulic circuit wherein the output from a pump 2 is supplied through a line 1 to a servomotor 3 arranged, when pressurized, to maintain open a stop valve (not shown) in the steam supply line to a turbine driving an electrical generator having overspeed monitors 4-7 which are operable if the turbine speed becomes excessive to cause actuation of associated slide valves 8, 9 and consequential collapse of pressure in the line 1, a test circuit is provided whereby the correct functioning of the monitors can be tested without causing the servomotor 3 to be de-pressurized. As shown, the overspeed monitors are arranged in pairs 4, 5 or 6, 7 and each has an identical and separate test circuit. Each test circuit comprises a by-pass line 13, 14 containing a by-pass valve 15 and a pressure actuated relay valve 18 having a line 27 leading to a test lamp 28. The valves 15, 18 are normally in the positions shown, in which the pump pressure in the line 1 is fed through branch lines 26, the relay valves 24 and the lines 27 to cause the lamps 28 to be extinguished. If the functioning of the monitors 4, 5 is to be tested the appropriate by-pass valve 15 is manually operated to cause the line 13 to be pressurized. Pressurization of line 13 acts through a line 16 to cause the relay valve 18 to changeover, thus depressurizing the line 27 and lighting the lamp 28. The lighting of the lamp 27 is arranged to send an electrical signal to the actuation device of the monitor 5 to thereby cause the slide valve 9 thereof to changeover. Although the monitor 5 has been operated, the supply to the servomotor is maintained from the line 13. As a result of fluid from line 1 having to flow through the lines 14, 13, pressure in the line 16 falls, so that the relay valve 18 is returned to its former position by pressure in a branch conduit 17. The changeover of the valve 18 causes, firstly, the lamp 28 to be extinguished, and secondly, a signal to be sent to the monitor 4 which consequently changes over, to thereby exhaust pressure from the conduit 17. Hence the relay valve 18 is again changed over causing re-lighting of the lamp 28. Assuming both monitors are operating satisfactorily the sequence continues with the alternating lighting and extinguishing of the lamp 28 until finally the by-pass valve receives a signal causing it to return to its original position.
