Title: Improvements in gyro-stabilized platforms
Inventor: SINGLETON HENRY EARL
IPC: G01C21/18
Filed: 1959-08-19
Abstract: 924,093. Automatic control systems for gyroscopic apparatus. LITTON INDUSTRIES Inc. Aug. 19, 1959, No. 28299/59. Class 38 (4). [Also in Group XX] A platform is automatically stabilized in attitude by two two-degree of freedom gyros having one sensitive axis in common, the platform being effectively set to the mean of two positions about this axis demanded by the two gyros when these differ due to drift. In Fig. 1, two gyroscopes A, B (not shown), having their spin axes horizontal and mutually perpendicular, are respectively mounted each for two degrees of freedom in boxes 12, 13 attached to a platform 11 which is rotatable relative to a member 18 supported in gimbals relative to the structure 14 of a moving vehicle. Amplified signals from a pick-off associated with the vertical axis of gyro A control a servomotor 35 which operates to maintain platform 11 fixed in azimuth. Amplified signals from a similar pick-off associated with the vertical axis of gyro B, which may have drifted in azimuth differently from gyro A, are applied to precess gyros A, B in opposite directions towards a common position in azimuth. Signals from pick-offs associated with the other axes of gyros A and B are suitably modified and combined by a resolver 48, operated by movements of the vehicle in azimuth, so that when applied, after amplification, to servomotors 37, 40, platform 11 is maintained fixed in space relative to the roll and pitch axes of the vehicle. Tilt of platform 11 relative to gimbal ring 17 is eliminated by applying amplified signals from a pick-off 49, responsive to such tilt, to a servomotor 42 to move outer gimbal ring 16. Coarse and fine synchros 45, 46 associated with platform 11, synchro 50 associated with gimbal ring 17, and synchro 51 associated with gimbal ring 16 produce signals corresponding to the attitude of the vehicle about the three mutually perpendicular axes defined by platform 11. The outputs of accelerometers 30, 31, 32 measuring accelerations in the directions of the three axes may be integrated to compute velocity and/or position of the vehicle and these signals may be combined with signals representing the velocity of the earth and utilized to torque the gyros so that the platform is maintained fixed relative to the earth vertical as the vehicle moves over the earth's surface.

[Class 89 (iii).] A nail-assorting mechanism is provided with a device for removing misplaced nails from the raceway comprising two members which act on a misplaced nail by their relative movement in the direction of the raceway. The device is described as applied to the machine described in Specification 1494/93, [Class 89, Nails &c.], when adapted for handling Cutlan Bills. The machine may embody the features described in Specifications 303,780 and 312,956, [both in Class 89 (iii), Nailing &c.]. A member 1 slidable on an arm 2 is held downwardly on the latter by a spring 3. The arm 2 is fast on a rock shaft 6 on which is also fast a lever 8 carrying a roll 9 co-operating with a cam 10. A second member 16 is slidable, under the action of a spring 17, in a bore in the raceway cover block 14. When the lever 8 is pulled downwardly by its spring 11, the member 16 is forced into its bore. In the operation of the machine, the lever 8 is rocked by the cam 10. The toe 20 of the member 1 will then engage any nail, such as 19, Fig. 4, the point of which has become wedged beneath the raceway cover, and move it up the raceway. The member 16 simultaneously advances so that its toe 21 closes the entrance to the raceway cover. The member 1 then swings back, allowing the nail to slide down against the toe 21, and finally returns to the position shown in Fig. 1. In its return, it engages the point of the nail and throws it off, or properly into, the raceway. Specification 209,824, [Class 89 (iii), Nailing &c.], also is referred to.

Title: Filtering apparatus
IPC: B01D63/16
Filed: 1964-07-14
Abstract: 1,075,785. Filters. G. GAUDFRIN. July 14, 1964 [July 16, 1963], No. 28940/64. Heading B1D. Filtering elements 8 of a filter unit mounted on a central shaft 4 are successively immersed in adjacent radial compartments of a circular tank 1 containing liquids to be filtered and different washing solutions, passage of the element from one compartment to another being effected by a lifting mechanism synchronised with a rotating mechanism for the ring 6 on which the elements are fixed by bearings 7. The elements 8 pivot in planes radial to the ring 6. To cross a partition an element is raised by a pneumatic or hydraulic jack 13 operating a level 14 which bears against a sleeve 16. A jack pushing a pawl then advances the filter element held lifted by a cam 17 above the partition. At the end of the movement the sleeve 16 is pushed under a lever held by a damping spring and the elements resumes their filtering position within the tank. The filtrate is emptied out when the element is in its raised position. Each filter element may comprise the filtering support with fluid tight outer faces and filtering inside faces. When the deposit in the supports becomes such that the supports become solid with one another the pressure of the supports against each due to vacuum or pressure assists in drying the deposit. When the vacuum or pressure is broken a spring forces the plates apart. The apparatus may be enclosed in a casing.
