Title: Self correcting guided missile - uses ineria detectors showing discrepancies between theoretical and actual trajectories
IPC: F42B15/01
Filed: 1962-10-23
Granted: 1975-02-28
Abstract: The missile follows a theoretical trajectory as close as possible to the free trajectory of the same missile without guidance under ideal conditions with no disturbing factors. The integrating liquid inertia accelerometer can be used to measure the speed on board a vehicle travelling in the horizontal direction. It uses inertia detectors to show the discrepancies between theoretical and actual trajectories. These have no component moving rapidly in relation to the frame, and use only simple electrical devices and low-power sources. They are mounted as close as possible to the controls using the data supplied by them.

Filed: 1936-01-13
Abstract: 468,838. Grading fruit &c. by weighing. OXLEY, J. Jan. 13, 1936, No. 1064. [Class 143] In a machine for grading fruit and other articles, the articles are carried singly in cups pivoted on an endless belt or chain by means of hinge pins disposed longitudinally of the belt and each cup is provided with an upwardlyprojecting arm adapted to slide along a stationary rail containing counterpoised bridge sections which yield under predetermined loads and permit the cups to tilt and discharge the articles according to their various weights. The articles 8 are brought to the grading cups 7 by an endless travelling belt 21 passing over a small roller 22, and are deposited singly in the cups with the assistance of a rubber buffer 27 and a loose trailing lever 23. The cups are attached to the endless running belt 2 by means of transverse members 15 and hinged pins 6 disposed longitudinally of the belt. Upright arms 9 rigid with the cups slide along stationary gapped rails 10, the gaps being closed by bridges 11 forming part of counterweighted levers 14. If the article in the cup is sufficiently heavy to overcome the resistance of the counterweighted lever the arm 9 rocks into the position shown by broken lines in Fig. 3 and the article is tipped down its grade shoot 19. If the article produces only a partial movement of the counterweighted lever, the continued movement of the belt 2 brings the upright arm 9 into contact with a pivoted section 17, Fig. 1, which is displaced as shown by broken lines to allow the upright arm to rock and discharge the article. In order to re-engage the upright arms with the rails, the belt pulley 3 is provided with a pair of flanges 20 adapted to maintain the cups in their raised positions as they pass round the upper portion of the pulley.

Title: Improvements in or relating to the electric tuning of the natural frequency of a cavity resonator
IPC: H01P7/04
Filed: 1950-01-17
Abstract: 684,033. High-frequency discharge apparatus. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 17, 1950 [Feb. 4, 1949], No. 1258/50. Class 39(i) [Also in Group XL(c)] Electronic tuning of a low-pressure gas-filled cavity resonator is effected by producing therein a discharge, the position of which is varied under the control of an externally applied direct voltage. The resonator, Fig. 1, comprises a coaxial line having an inner conductor I and an outer conductor E surrounded by an envelope A which is connected to the inner conductor and is sealed by insulating closure members B and C. Lead-in wires a and b serve to couple the resonator to its load circuit, the parts of the conductors inside the resonator acting as resonant coupling loops. The inner conductor I increases in diameter towards one end which is provided with a bore D in which is placed an insulating cylinder G supporting a plurality of metal rings S spaced apart by insulating rings which are represented in the drawing by thick lines H. The capacity between adjacent metal rings is sufficiently high for the system to behave as a continuous conductor for the high-frequency currents. One pole of a battery U is connected by a lead-in wire F to the outer conductor E and the other pole is connected through a switch L to any one of a series of lead-in wires K connected to the metal rings S. Tuning of the resonator is effected by the discharge which occurs between the outer conductor E and one of the metal rings S selected by the switch L which may be of any known type, particularly an inertia-less electronic type. In a modified arrangement, Fig. 2, particularly applicable when a continuous variation of frequency is required, as for example in frequency modulation circuits, the discharge occurs between the outer conductor E, which forms the envelope, and a tapered portion M of the inner conductor, which is separated from the outer conductor by an insulating member P, and is separated from the portion I of the inner conductor by an insulating member N in order to isolate the. portion I from the direct voltage initiating the discharge. The position of the discharge and consequently the frequency of the resonator is varied by altering the current in the discharge circuit by means of a variable resistance R which may be replaced by any known control means. A cavity resonator as shown in Fig. 2 may be included, as the frequency determining element in the reaction channel of the travelling-wave valve oscillator described in Specification 667,208, [Group XL(c)].

Abstract: 873,146. Automatic fluid flow control systems. SPE CO. Ltd. Jan. 14, 1958 [Jan. 14, 1957; July 29, 1957], Nos. 1401/57 and 24007/57. Class 38 (4). In a system for maintaining rates of fluid flow in a desired ratio, electrical pulses corresponding in frequency to the rates of flow operate step by step motors coupled through adjustable speed gearing to driven members which get out of step and operate means to control fluid flow and restore the desired ratio automatically, should it deviate. In Fig. 1 fuel is pumped from each of three aircraft fuel tanks 10, 11, 12 by pumps 13 through conduits 14 having electric motor-operated control valves 15, non-return valves 16, and flow measuring units 17. The flow transducing units are of the type in which a rotor driven by the fuel flow carries a vane which periodically interrupts light falling on a photo-transistor or operates an electromagnetic device so that electrical pulses are produced having a frequency corresponding to the rate of flow. These pulses, amplified, operate step-bystep motors 20 rotating ratchet wheels 22 to positions corresponding to integrated rate of flow in each conduit 14. Ratchet wheels 22 drive further wheels 25 through variable-speed gears 24 which are set so that when the flows are in such ratios that the three tanks empty together there is no relative movement between the three wheels 25. If relative movements do occur, indicating errors in the flow ratios, reversing switches 65 are operated to run the motors of control valves 15 in the appropriate direction to correct the ratios. Ratio correction by controlling by-pass valves returning fuel to the tanks or by varying pump speeds is referred to. Counters and speed-responsive devices operated by the pulses or by ratchet wheels 22 and by a shaft 32 indicate individual and total flows and rates of flow respectively. An emergency pump may be started to replace a main pump by a switch responsive to failure of pressure in one of the conduits.
