Title: Gyroscopic instruments
IPC: G01C19/44
Filed: 1945-12-17
Abstract: 626,634. Gyroscopic apparatus. BENDIX AVIATION CORPORATION. Dec. 17, 1945, No. 34116. Convention date, Dec. 26, 1944. [Class 97 (iii)] [Also in Group XXXV] A gyroscopic altitude indicator comprises a rotor with a normally vertical axis mounted in a casing 21 on longitudinal minor trunnions 22 carried by a normally horizontal gimbal ring 23 supported by transverse minor trunnions 24 in the yoke 25 which is mounted on longitudinal major trunnions 26 in a casing 28. A spherical indicating surface 31 bearing an artificial horizon is carried by the rotor casing and is visible through the glass 29. An electrical mechanism 52, 53, 54 responds to angular deviation between the rotor casing and the gimbal ring 23 giving a signal to cause a motor 36 to effect an angular adjustment of the yoke 25 to maintain the rotor spin axis substantially normal to the trunnion axes. This provision prevents alignment of the trunnion axes with the rotor spin axis and consequent damage to the gyroscope. The connections 55, 56 from the signal generating mechanism are reversed when passing through the trunnion 24, twice in each revolution so that the correct yoke adjustment is made over the whole 360 degrees of rotation of the rotor casing. These connections are completed through brushes 61 and slip rings 57, 58, which are each provided with two spaced conducting sections 79, 80, Fig. 5, insulated from each other. The signal generating mechanism comprises a soft iron vane 52, Fig. 2, on the rotor casing trunnion and a stator 53 having a split coil 54 on the gimbal ring 23. Movement from the normal position shown in Fig. 2 causes a difference in reactance of the two halves of the coil 54 which are supplied in series from a transformer 67, which difference generates a current in the mid-point conductor 69 which signal is amplified and used to excite the variable winding of a two-phase induction motor causing rotation of the yoke through gearing 34 to return the gimbal ring 23 to'its normal position with respect to the rotor casing. The rotor motor is supplied, e.g. with 3-phase current from conductors 43 through slip rings 41, 46, 49 on the gimbal trunnions. The rotor may be erected as described in the Specification 441;439. Specifications 618,411, [Group XXXVIII], and 626,635 also are referred to.

Abstract: 343,437. Fluid-pressure brakes. CARROLL, E. G., 1038, South Hobart Avenue, Los Angeles, U.S.A. Nov. 11, 1929, No. 34388. [Class 103 (i).] Hydraulic brake apparatus comprises a foot-operated cylinder connected to the brakes through a hand-operated cylinder which augments the pressure produced by the foot. The pressure produced by the foot-operated cylinder is transmitted by a pipe to a port 28 in the hand-operated cylinder 21 and through ports 37 in an extension 29 of the hand-operated piston, to a pipe 40 leading to the brakes. Movement of the hand lever 25 moves the piston 26 and the extension 29 so that the latter closes the port 28 and is held in this position by a spring 34. The piston 26 slides in the extension 29 and increases the pressure of the liquid thus trapped. The cylinder is provided with a double head comprising an inner head 41 held between the two sections 21,22 forming a chamber 32a connected to a liquid reservoir through a check valve 32d. Spring-pressed packing rings 44, 47 are provided. The foot-operated cylinder comprises a piston having a tubular extension 10, Fig. 2, guided in a bore 16 and forming with the cylinder bore a chamber 11 communicating with the liquid reservoir which keeps the apparatus full of the operating liquid through a port 14 in the extension 10 when the piston is in the position of rest. A packing ring 19 is held in place by a spring 17. The wheel brakes comprise shoes applied to the inside and the outside of the drum by hydraulic cylinders 61, 62 having an intercommunicating aperture 76. The cylinder 62 operates the external shoes 55 by means of levers 66, having bent extensions passing through the brake back-plate. Springs 70 heaving against a fixed abutment 71 and nuts 72 hold the shoes 55 away from the drum.

Draw-gear; couplings, automatic, coravertible to non-automatic. - In a supporting device for the automatic coupling-head of a transition coupler for railway vehicles of the kind claimed in the parent Specification, the head, in addition to being supported on the drawbar or draw-hook by means which transmit tractive forces only, is held in a central position by rodding pivotally connected under spring influence at one end with the coupling-head and at the other end with the vehicle underframe, such thrust rodding being capable itself of a resilient extension and contraction. In the construction shown in Figs. 1 and 3 the coupler-head 1 is pivotally connected at 26 with the draw-bar 27 through the medium of a plate 6<1>, while the connection to the underframe comprises a pair of telescopic pivoted tubes 2, 3 fitted with internal springs and united by a yoke 5, 5<1> working in eyes 9 on arms 17 fixed to a transverse rotatable shaft 15. During traction the telescopic tubes 2, 3 are extended simultaneously with the compression of the draw-gear springs, while small shocks cause a pivotal movement of the tubes about the axis 11. When it is desired to use the non-automatic screw coupling, the coupler-head and supporting-members may be swung down together by operating a handle 28 on the shaft 15. To give further resilience to the supporting arrangement a spring 24 may be located between the tubes 2, 3 and extensions 21 of the arms 17. In a modification, Fig. 4, the connection to the draw-bar 27 comprises tension bolts 6<11> and pivoted links 7<11>, while the connection to the underframe comprises pivoted links 5<11> movable in elongated eyes 19 at the ends of the telescopic tubes 2, 3, which are mounted on fixed brackets 20. In further modifications the links 5<11> of the last construction are replaced by jointed links, and the upper support is from a draw-hook, the telescopic tubes 2, 3 being either fixed to or pivoted on underframe brackets.
