Abstract: A cup-shaped member is attached to a rotating shaft as might be associated with a turbine meter for measuring fluid flow or volume. A permanent magnet ring is mounted internal to the cup member, the ring having a plurality of equispaced alternating north and south poles. A second cup-shaped member is mounted within the permanent magnet ring having a plurality of coils mounted on an iron core therein having non-salient poles, whereby uniform reluctance in the magnetic circuit is maintained regardless of the angular position of the shaft. In an alternative embodiment, the ring is iron, having the coils mounted thereon, and the permanent magnet is made to rotate in the center portion of the ring. Circuitry is also described to convert the voltage output from the generator into fluid volume indications as dictated by the rotation of the shaft, such circuitry including a first rectifier connected to an alternating voltage, a rechargeable battery connected to the output of the first rectifier, a second rectifier connected to the alternating voltage and a trigger flip-flop circuit powered by the rechargeable battery and connected to the output of the second rectifier whereby a series of sharply squared output pulses are produced at the output of the trigger circuit in response to the rotation of the shaft. In addition, circuitry is provided for scaling down the number of sharply squared output pulses by a predetermined number whereby the output of the scaling circuit provides a predetermined number of output pulses according to the conventional units of flow as determined by the rotation of the shaft.

Abstract: THREE INDIVIDUAL LUBRICANT RESERVOIRS ARE POSITIONED IN A THREE CONE ROTARY ROCK BIT WITH ONE OF THE RESERVOIRS IN EACH OF THE THREE ARMS OF THE BIT FOR SUPPLYING LUBRICANT TO THE BIT BEARING SYSTEMS LOCATED BETWEEN EACH OF THE THREE INDIVIDUAL CONE CUTTERS AND THE BEARING SHAFTS UPON WHICH THE ROTATE. A SEAL IS POSITIONED BETWEEN EACH OF THE CONE CUTTERS AND ITS BEARING SHAFT TO PREVENT THE LUBRICANT FROM ESCAPING INTO THE BOREHOLE AND TO PREVENT HOREHOLE FLUIDS AND DEBRIS FROM ENTERING THE BEARING AREA. A PASSAGEWAY EXTENDS FROM EACH OF THE LUBRICANT RESERVOIRS TO THE EXTERIOR OF THE BIT AND A FREE BREATHING POROUS FILTER PLUG IS POSITIONED IN EACH OF THE PASSAGEWAYS THEREBY EQUALIZING THE INTERNAL PRESSURE OF LUBRICANT IN THE LUBRICANT RESERVOIR AND THE HYDROSTATIC PRESSURE OF DRILLING FLUID IN THE WELL BORE.

Abstract: A bistable multivibrator or scale of two circuit is inserted in the sync pulse line before a pulsed neutron generator to reduce the pulse repetition rate by a factor of two. The radiation detection system within the borehole instrument is gated in the conventional manner without the repetition rate of its detection gates being reduced by the factor of two. A second bistable multivibrator circuit is inserted in the sync pulse line before the sync pulse cable driver, the second multivibrator circuit causing the surface electronics to accept signal information during the first half of an elongated cycle which has not been corrected for activation background, and to accept information during the second half of the cycle which relates only to activation background. The signal information is combined with the background information to provide data relating to the decline of the thermal neutron population which is independent of the activation background counting rate.

Abstract: A butterfly valve construction having an outside indicator for indicating vane relation between open and closed positions of the valve. A single assembly mode between the vane, drive shaft and outside indicator assures accurate exterior indication of vane relation. Vane operating force is transmitted through a replaceable shear pin which, in event of operating interference, fractures to prevent damage to other valve components.

Abstract: An improvement in an automatic coupling system for a railway car which is equipped with a mechanical coupler, a main air line adapted to be connected to a corresponding air line of another railway car, a main valve interposed in the main air line, and means for actuating the main valve responsive to intentional coupling of the railway car. The improvement, in its preferred form, takes the form of a pair of pilot-operated check valves connected in parallel to the air conduit supplying the actuating means to prevent flow of air therethrough when the main air line is charged but uncoupled at one end, and to maintain the flow therethrough when coupled to another car but with either car having a faulty interface valve actuation which would normally allow the main valve to close.
