Abstract: 814,956. Bearings. ETABLISSEMENTS NEYRPIC, ATELIERS NEYRET-BEYLIER ET PICCARD-PICTET, and GROS, C. May 28, 1957 [May 28, 1956], No. 16955/57. Class 12 (1). [Also in Group XXVI] In a turbine-driven drill for well-boring, a thrust supporting device for the rotatable shaft forming the turbine rotor is constituted by elementary thrust bearings which are incorporated in the bladed parts of the turbine. The turbine unit comprises an outer stator casing 14 which is supported at the lower end of the drill pipe, the stator blade elements 6A being secured within the casing by means of a lock-nut 13. The rotor shaft 11 has rotor blade elements 6B mounted thereon and secured by a lock-nut 12, the shaft 11 carrying at its lower end the drill bit. The working fluid enters the casing at O and after passing through the blade stages discharges through the centre of the shaft 11 around the drill bit. U-section rings 8 of moulded rubber are disposed round the shroud rings 7 of'the stator blades 6A, the cylindrical part of each ring 8 bearing against a spacer ring 9 disposed between each pair of adjacent rotor blade elements 6B, and the flange portions of each ring 8 bearing against the radial faces of the adjacent rings 10 of the rotor blade elements 6B. The rings 8 thus constitute radial and thrust bearings for supporting the rotor within the stator casing. The rings 8 may be formed of either natural or synthetic rubber or of a bearing metal. There may be a bearing on each stator blade shroud ring or only on say one in every three shroud rings. The blades mounted on the shaft may constitute the stator blades, the casing 14 then constituting the rotor. The shaft 11 may increase in diameter in steps from adjacent the inlet end so that the blades of the inlet end are longer than those remote therefrom, and the area of the thrust bearing associated therewith is larger.

Title: Improvements in or relating to radio direction-finding apparatus
IPC: G01S1/02
Filed: 1947-06-30
Abstract: 651,839. Automatic control systems for direction-finding apparatus. SPERRY GYROSCOPE CO., Inc. June 30, 1947, No. 17201. Convention date, July 13, 1946. [Class 38 (iv)] [Also in Group XL (c)] An automatic control system is employed in a radio direction-finding apparatus (see Group XL (c)), to maintain a directional antenna, such as a loop, in angular correspondence with the direction of received energy. The loop signals are combined with those from a non- directional sense antenna but are first modulated or modified cyclically for periods which differ from one half of the cycle period so that the detected combined signal is an asymmetric wave in which the polarity and amplitude of the excursions from the mean value depend upon the sense and degree of loop misalignment, two oppositely connected peak-signal rectifier circuits being provided to derive from this asymmetric wave a D.C. differential potential, of sign and magnitude dependent upon the misalignment to operate an electric motor controller whereby the loop is rotated into unambiguous angular correspondence with the received energy. In Fig. 1 the signals from loop antenna 1 are combined with those from sense antenna 10 in a receiver 9 after modulation in unit 2 and a 90 degrees phase shift in unit 8. Figs. 4 and 5 (not shown) illustrate one form of modulater in which a pair of amplifying valves in push-pull combination are rendered conducting alternately by asymmetric square wave keying voltages so that the loop signals are subjected to periodic reversals of unequal duration before combination with the sense signals. An alternative modulater, Figs. 6 and 7 (not shown), employs an asymmetric square-wave keyer to operate a relay and alternately connect and disconnect the loop signals for unequal periods of time. Other asymmetric modulating waves may be employed such as an alternating wave comprising a fundamental and at least one harmonic. The combined signals are detected in receiver 9, Figs. 2 and 3, showing the radiofrequency and corresponding detected waves. With the loops in the null position its output is zero and the signal is that due to antenna 10 alone as shown in curve A. With the loop displaced to one side the combined signal is as shown at B and C for two degrees of misalignment. Displacement to the other side removes the phase of the loop signals and the output appears as as D or E. The detected signals are applied to a pair of peak-signal rectifier circuits 17, 18 which develope potentials proportional respectively to the peaks of the positive and negative excursions from the mean value (shown dotted) and a difference potential for application to a motor controller 14. The controller actuates motor 15 to rotate the loop.
