Title: Gyroscopic navigational control system for aircraft
IPC: G01C19/44
Filed: 1953-04-20
Abstract: 734,148. Gyroscopic apparatus. SUMMERS, T. O. April 20, 1953, No. 10819/53. Class 97 (3). [Also in Group XXXV] A gyroscopic navigational control system for an aircraft includes a gyro rotor supported. within a casing rigidly supported by the aircraft by at least a roll gimbal, means for case erecting the gyro rotor about the roll axis of the aircraft to a straight flight reference position determined by the average position in space assumed by the aircraft about its roll axis, and. means controlled by the gyro rotor when in said reference position to maintain the straight flight attitude of the aircraft. As shown in Fig. 6, the gyro-vertical has a rotor 26a mounted for spinning about a vertical axis in an inner gimbal 23 which is rotatable about the roll axis of a craft in bearings 24, 25 in an outer gimbal 12 itself rotatable about the pitch axis of the craft in bearings 14, 15 (Figs. 3, 5) in a casing 1 fixed to the shaft. The rotor 26a has a dome 27 and is driven by an electric motor supported within the inner gimbal, grounded to the outer gimbal and supplied with power through a plug 30 (Fig. 3) and contact plates 39, 40, on the gimbal 12. Pivoted about the pitch axis of the craft is a pendulous bail 56, Figs. 5, 6, which curves around the rotor dome 27 and carries a plate 61 supporting a resilient plate 67 having thereon a projection 70 which bears against the dome 27 with a pressure adjustable by a screw 69. Two stops 66a on the casing 1 co-operate with a buffer ring 66 on a downwardly-bent section of the plate 61. Projection 70 is normally aligned with the rotor spin axis and the frictional force between it and the rotor dome 27 causes precession of the gyroscope in the event of misalignment. Any movement of the casing 1 about the roll axis effects a corresponding movement of the bail 56 about this axis, the gyro spin axis following this movement so that the gyro is case erected in roll. Since the bail is pendulous about the pitch axis, the gyro is gravity-erected about the pitch axis. In the modification shown in Fig. 15, a visual indicator is provided. One section 1a of the casing 1 is transparent and an indicating dial 170 is supported on one of the inner gimbal axes, the face of this dial bearing transverse lines 172 and a vertical line 173. The transparent section 1a has a transverse indicating member 174 having an enlarged central opening 175 through which the lines on the dial can be seen. The member 174 co-operates with the transverse lines 172 to indicate dive and climb. Lines 176 on the section 1a co-operate with vertical line 173 on the dial to indicate the amount of bank of the craft.

Abstract: 1,170,445. Making char from coal. COAL INDUSTRY (PATENTS) Ltd. 7 March, 1967 [11 March, 1966], No. 10843/66. Heading C5E. In a method of heat-treating carbonaceous particulate material in a fluidized bed in which an oxygen-containing gas is used to fluidize the bed, at least two separators, preferably cyclones, are arranged in series with the gas offtake from the bed, and fines from the first separator only are returned to the bed, preferably to the dense phase of the bed. Fines from the second separator may be delivered to the outlet for the treated material. The process is applicable to heattreating coal to make char for briquetting, e.g. at 380‹ to 480‹ C., and the invention reduces the O 2  content of the gases above the bed and lowers the temperature above the bed.

IPC: H01R13/707
Abstract: 115,275. Donovan, W., and Donovan, G. O. May 4, 1917. Plug couplings combined with electric switches. The detachable plug part a of a plug-and-socket coupling is provided with an axial switch-operating member h, i extending through the plug member. When the plug member is in place, the pin h passes into a central hole o in the socket-holder l at the back of which the movable contact - carrying member w of the switch is located. A sleeve q having inwardly - projecting pins is loosely mounted in a recess in the socket-holder; one of these pins is engaged loosely by a slot u, Fig. 4, in the operating-member h and the other pins loosely engage slots in the outer end of the spindle p carrying the member w. Contacts x are mounted on the member w, which is in the form of a disk, and co-operate with contacts fixed above and below them. A quick-break action is produced by a metal cam piece 3 mounted on the member w, and in electrical connexion with the spindle p, co-operating with leaf springs 2, the lost-motion connexion between the operating-member and the switching-member allowing of this action. When the switch is turned to the ' on ' position by means of the handle i, a face on the operating- member h formed by a groove cut therein is engaged by a pin w thereby locking the plug to the socket part when the switch is in the closed position. The operating-handle is earthed by its connexion with the earthed casing m, 11 through the pins 8, the plate 7, the springs 2, the cam 3, the spindle p, the sleeve q, to the operating- spindle h. To ensure that the loose sleeve maintains effective contact with the spindle elements, the sleeve q is pressed laterally by the spring 5 into engagement with these elements. The plug casing also may be earthed by an earthing lead connected to a socket c mounted in the insulating-block b which carries the plugs and is connected with the plug casing by a screw g. The plug part is held to the socket part by a flanged ring 17 and a water-tight union is obtained by means of a rubber disk 20 and a rubber ring 19. One of the plug contacts may be larger than the other to ensure correct insertion of the plug member.

Title: An apparatus for the evaluation of x-ray photographs
IPC: G01N23/205
Filed: 1957-04-09
Abstract: 824,994. Calculating-apparatus. KHOL, F., and TALAS, J. April 9, 1957 [April 12, 1956], No. 11535/57. Class 106 (1). A device for determining the crystal lattice parameters d corresponding to lines on an X-ray photograph of the Debye-Schrrer type enables an arm to be set in accordance with the glancing angle # for a chosen line and to be used to determine d from Bragg's equation, sin # = A/2d. The photograph 1 is mounted in a transparent cylindrical chamber 2 having a radius double that of the camera in which the photograph was exposed. The arm 5 is pivoted on the axis 4 of the chamber and carries an optical sighting arrangement 6, 7 whereby a chosen line may be viewed by setting the arm in a corresponding angular position. Since the radius of the chamber is double that of the camera, the arm will then make the angle # with a zero line passing through the axis 4 and the centre of the film. Immediately beneath the arm 5 is a transparent plate 3 bearing lines 11 parallel to the zero line and at distances from it corresponding to various values of #/2 for different characteristic wavelengths, e.g. Kα and K#. Thus, the length of the arm 5 to its intersection with the appropriate line 11 represents d. The value of d is read from a scale on the arm by means of a cursor 9 having a cursor line intersecting the scale and a perpendicular line in line with the axis 4, the actual arm 5 being slightly offset.
