Patent GB-606058-A (GB)
Abstract: 606,058. Bore-hole apparatus. DEHN, S. G. (Grant Oil Tool Co.). Jan. 9, 1946, No. 819. [Class 85] A well tool of the expansible cutter-type him a hollow tubular body 11, having formed in the wall a number of slots 20 in which cutters 21 slide radially, each having wedge surfaces 26 and 27 formed on the inner face. These surfaces abut wedge surfaces of plungers, both capable of axial movement relative to each other. The plunger 29 slides along a wash pipe 31 welded to the plunger 28, water-tight connections being formed between the wash pipe and the plunger 29 and between the plungers 28, 29 and the casing. A spring formed of two elements 38a and 38b normally keeps the cutters in the retracted position during lowering and raising of the tool whilst they are expanded by fluid pressure acting on the outer ends of the plungers. The pressure is built up, due to a constriction 18 in the flow passage between the bore of the body and a pilot cutter 19. In one modification the portions of the spring are normally in the expanded position. Another modification is that the passage is reduced by a holed bush so that the restriction of flow and subsequent increase in fluid pressure is independent of the tool at the end of the body 11.

Abstract: 741,960. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Ltd. June 25, 1954 [July 17, 1953], No. 19842/53. Class 97 (3). Gyroscopic apparatus of the kind in which a rotor is mounted for spinning in a rotor case pivoted about a first gimbal axis perpendicular to the spin axis of the rotor in a gimbal frame which is itself pivoted about a second gimbal axis perpendicular to the first gimbal axis and normally perpendicular to the spin axis, in which means are provided for controlling the support to cause a reference line in it to be maintained parallel to the spin axis of the rotor, and in which means are provided for applying precessional torques to the rotor case, is characterized in that the torque-applying devices, each of which operates when energized to apply a force directly between the support and the rotor case about an axis lying in the plane containing the gimbal axes and inclined at an angle to each of those axes. As shown in Fig. 1, the gyroscopic apparatus is mounted on a base-plate 1 fixed to the aircraft or missile to be controlled. The electrically-driven rotor is mounted in a casing 5 pivoted in bearings 10, 11 (see also Fig. 2) in a gimbal ring 9 which is in turn pivoted on pillars 12, 13 on the base-plate 1. For precessing the rotor, torque motors 16, 17, 18, 19 are mounted on the base-plate. The motor 16 comprises arms 21a, 22a joined by a yoke 23a to form an electromagnet. Only one of the energizing coils for motor 16 is shown in Fig. 1, but the coils for motor 17 are shown at 24b, 25b. The rotor casing has four projections around which a coil 20 is wound (see also Fig. 3), the coil passing between the poles of the magnets of the torque motors, so that each motor, when energized, exerts a torque on the rotor casing about an axis in the plane of the gimbal axes but at an angle of 45 degrees to each axis. Current to coil 20 and to the spin motor is supplied through a cable 32, which passes through the gimbal bearings and is supported by brackets 33, 34 on the gimbal ring. A partspherical projection 26 (Fig. 3) of magnetic material on the base of the rotor case 5 cooperates with coils 27, 28, 29, 30, 31. on a laminated five-pole core mounted on the base and embedded in plastic material. The central coil 27 is energized with high-frequency A.C., and the other coils are connected in opposition so that an error signal is produced when a line fixed with respect to the base and the rotor axis are out of alignment. The error signal acts on control surfaces of the craft or missile carrying the apparatus in known manner to bring the fixed line back to its alignment. When the direction of flight is to be changed, one or more of the torque motors 16, 17, 18, 19 is energized to process the rotor axis to a new direction.
