Title: Electromagnetic prospecting apparatus
IPC: G01V3/165
Filed: 1958-10-21
Abstract: 899,607. Electric tests. INTERNATIONAL NICKEL CO. OF CANADA Ltd. Oct. 21, 1958 [Oct. 24, 1957], No. 33633/58. Class 37. Apparatus for detecting and measuring conductive and magnetic bodies comprises means for transmitting at least two primary electromagnetic fields at different frequencies, means for transmitting a reference field at a third frequency, means for receiving and detecting the signals due to these fields, including the responses caused by the presence of conductive or magnetic bodies, and means for comparing the detected signal at the reference frequency with the detected signal at each of the primary frequencies. As shown, in airborne apparatus for detecting and measuring ore deposits, three A.C. sources 10, 11, 12 in an aircraft 13 are connected to transmitter coils 14, 15, 16, respectively, primary coils 14, 15 being disposed in parallel planes and the reference coil 16 being set in a plane perpendicular thereto. Primary receiving coils 18, 20 and a reference receiving coil 22 are located in a bird 17 towed by the aircraft, each primary receiving coil being coplanar with one primary transmitting coil, and the reference transmitting and receiving coils being coaxial. Source 10 operates at a relatively low frequency F1, preferably in the range 100-1000 c.p.s.; source 11 operates at a higher frequency F2, preferably between 500 and 5000 c.p.s.; the reference frequency F3 may be near one of F1, F2, or may lie between them. Receiver coils 18, 20, 22 are tuned to frequencies F1, F2, F3, respectively, and the received signals are passed to filter and amplifying circuits 24, 26, 28, the outputs of which are combined in an amplifier and modulator 30. The modulated signal is fed through a conductor 36 in the tow rope between bird and aircraft to an amplifier and detector 38, the output of which is passed to filters f1, f2, f3, which pass the primary signals and the reference signal, respectively. The reference signal from f3 is compared separately with the signals from f1, f2 in comparing circuits 46, 48, the outputs of which operate pen or magnetic tape recorders 50, 52; alternatively, the outputs of circuits 46, 48 may themselves be compared to produce a single record. One transmitting coil radiating both primary fields may replace the two primary coils; similarly, a single primary receiver coil may be used instead of two. Misalignment between transmitting and receiving coils produces an error signal in a detector coil 23 which is orthogonal to the transmitting coils when they are correctly aligned; this error signal is amplified at 29, modulated at 31 and passed to a detector 39, the output of which is fed to means 53 for recording the extent of misalignment or for re-aligning the coils. Additionally or alternatively, the electro-optical system described in Specification 899,608 may be employed. The apparatus of the invention may be mounted in a helicopter, or in a land or water vehicle. Specification 899,606 also is referred to.

Title: Improvements in or relating to fluid-operated devices
IPC: F15C1/12
Filed: 1963-08-26
Abstract: 974,854. Fluid actuated calculating apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 26, 1963 [Aug 24 1962], No. 33642/63. Headings G4B and G4D. [Also in Division G3] A shift register and counter is described, each stage comprising combinations of mono- and bi-stable fluid amplifiers. In the shift register (Fig. 2) a signal from IN 0  or IN 1  deflects fluid from source 11 to the lower or upper wall respectively of a bi-stable amplifier. The walls 21, 22 form monostable amplifiers, the jet from source 11 normally flowing into passage 16 or 17 to provide the control signal for a second bistable amplifier supplied from source 12. The signal from source 12 is normally directed either to port R 0  or port R 1  whereby the state of the stage can be sensed. The walls 26, 27 comprise monostable amplifiers. If the stage is storing zero, the jet from source 11 is attached to wall 22 and is steered to passage 17 so as to direct the jet from source 12 into port R 0 . Ports OUT 0  and OUT 1  are connected to the ports IN 0  and IN 1  of the next stage. To step the register, signals are applied to all the passages S, holding any monostable amplifier in its unstable state for the duration of the signal. This has the effect of directing the jet from source 11 to a sink 28, and the jet from source 12 to either OUT 0  or OUT 1  depending on whether it is flowing over wall 26 or 27. Fluid is then directed to either IN 0  or IN 1  of the next stage and the jet from source 11 is appropriately directed. On removal of the signals in passages S the stage assumes a stable state depending on the input signal just received. The binary counter (Fig. 4) has four sources, A and M for bistable amplifiers and No, N 1  for monostable amplifiers. In its zero state, flow from source M is along the lower passage 35 to hold the jet from source N 0  in its unstable position. The flow from source N 1  is directed along passage 16 to steer the jet from source A downwardly. A counting signal is applied simultaneously to the sources CI and CII. This sends all the monostable amplifiers to their unstable state and the jet from source A is directed to the port OUT 0  which is connected to port IN 0 . This sets the bi-stable amplifier which is supplied from source M so that its jet is directed into passage 39. When the counting signal is removed the bi-stable amplifier supported from source A is set by a jet from source N 0 . There is a take-off 40 from passage 35 connected to the inputs CI, CII of the next stage to cause transfer.
