Abstract: 513,305. Inductance, capacitance, and resistance measurements ; oscillographs; wireless transmitting apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Dec. 24, 1937, No. 35713. Void. Convention date, Dec. 29, 1936. [Class 37] [Also in Groups XXXVIII and XL] Voltages corresponding to electrical or mechanical phenomena are employed to modulate a high-frequency generator the output of which is supplied to a rectifier and the rectified current being applied to the circuit of an oscillograph. The energy from the generator may be radiated in space to the rectifier receiver, or the rectifier can be connected to the oscillograph by long leads. Stress variations, and pressure diagrams of prime movers can be recorded. Fig. 1 shows a high voltage supply to an X-ray tube 2, a characteristic curve of which is indicated on a cathode-ray oscillograph 16. A resistor 3 in the high-voltage lead is included in the anode circuit of screened oscillator 4 coil 6 of which inductively coupled to rectifier 14 through the coil 12. The rectified output across resistor 15 is proportional to the voltage across resistor 3 and is supplied to one pair of oscillograph plates, the other pair being fed from tappings on potentiometer 17 across the high-voltage supply. The grid bias of the rectifier can be varied to accentuate the trace of particular parts of the modulated current curve. The receiver circuits can be damped, and capacitance coupling between the generator and receiver can be employed, one form of such coupling being shown in Fig. 2, where the insulating supports 11 are hollow and have the coupled coils located on opposite faces. Mechanical phenomena are recorded by causing a variation of capacitance, inductance or resistance in a bridge circuit coupled with the generator, the modulated high-frequency oscillations in this instance being amplified before rectification.

[Also in Group XXI] A well-drilling assembly comprises means for by-passing the fluid supply to an hydraulic turbine, situated at the lower end of a drill string, when there is no load on a rotary drill bit driven by the turbine. In Fig. 2 the turbine casing 3 is connected to the drill string 2 and the motor shaft 4, which is hollow, has a splined extension 11 in which fits telescopically for limited relative axial movement a splined drill stem 13 carrying a bit 10. When there is a load on the bit 10, the stem 13 is pushed into its fully retracted position relative to the shaft extension 11 so that a shoulder 17 on a sleeve 15 closes ports in a valve seat 19 so that fluid circulating down the drill string passes through blading 7, through ports 9 and co-operating ports 16 in the sleeve 15 to the bit 10. When there is no load on the bit 2 the stem 13 slides to its fully extended position (as in Fig. 2) so uncovering the ports in the seat 19 and closing the ports 9 in the shaft 4 so that the fluid bypasses the blading 7. Small nozzles may be placed in the wall of the sleeve 15 above the ports 16 to allow a small circulation through the blading 7 when the sleeve is fully extended. In another embodiment, Fig. 4, a telescopic sub is placed between the drill string and the turbine, so that when the sub is in the contracted position shown, fluid depresses a spring- loaded valve 32 and passes to the turbine, but when there is no load on the drill bit and the sub is fully extended fluid passes from the interior of the sub through ports 30 into the borehole, so by-passing the turbine, the spring 33 closing the valve 32.
