Title: Guided missiles
IPC: F02K9/84
Filed: 1972-07-08
Abstract: 1386480 Deflecting propulsion jets BRITISH AIRCRAFT CORP Ltd 13 June 1973 [8 July 1972] 32088/72 Heading B7G A guided missile 2 has a jet pipe 1 encircled at its rear extremity by a part-spherical ring 14 spaced by an annular passage 15 from a partspherical extension 13 of a swivellable propulsion nozzle 10 having a throat 11 of smaller diameter than the jet pipe. The outer surface of extension 13 seats against a seal 9 formed in the inwardly turned end 6 of the missile body, within which is housed an annular member 3 formed with four equi-spaced cylindrical bores 4 housing pistons 19 connected by rods 18 to an annular flange 17 on extension 13. The open end of each cylinder is in direct communication with the space 16 within the missile body and the closed end is in communication therewith through a duct 23. The closed end of each cylinder is formed with a port 20 which is normally closed by a solenoid operated valve 22 and when the motor is run gas from jet pipe 1 is deflected by throat 11 through passage 15 into the space 16 so that a uniform pressure is applied to both faces of the pistons, the pressure on the connecting-rod-side of each piston being approximately twice the pressure on the other side, thereby relieving the load on a seal 8. Operation of a selected solenoid operated valve(s) will cause the corresponding piston(s) to be urged into the cylinder(s) with resulting deflection of nozzle 13.

Title: An ultrasonic flow meter system
IPC: G01H5/00
Filed: 1963-08-16
Abstract: 1,047,025. Ultrasonic fluid-flow meters. TOKYO KEIKI SEIZOSHO CO. Ltd. Aug. 16, 1963 [Aug. 24, 1962], No. 32458/63. Heading H4D. The flow velocity of a fluid 4 in a container is determined by emitting an ultrasonic pulse signal from a transducer 1 attached to a wall 3 of the container the ultrasonic pulse passing obliquely through the fluid to a second transducer 7 attached to an opposing wall 5 of the container. This received ultrasonic pulse is then converted into an electrical impulse which enters through switch 8 into an electrical transceiver 9, the output signal of which is conducted through switch 8 to the transducer 1 and transmitted once again through the system. This automatic emission of ultrasonic pulses is repeated a number of times and in addition the transducers 1 and 7 are switched alternatively at switch 8 from transmission to reception in equal time intervals by means of signal generator circuit 10 which gives an electrical impulse signal similar to that shown in Fig. 2A (not shown). Thus the direction of the ultrasonic wave is alternatively downstream and upstream resulting in an electronic signal being received by the transceiver similar to that indicated by Fig. 2B (not shown). The electronic signal may be converted into a visual signal by use of a cathode-ray tube or, as shown in Fig. 1, by employing a pulse motor 11, the output of which operates a reversible counter 12, and the rotation of which responds to the synchronous signal emitted by generator 10 which changes over switch 13 as well as 8. Then, by the switching of the phase shift condenser 14, the rotation of the pulse motor is reversed with the synchronous switching of the transducers, thereby obtaining f 1 -f 2 , i.e. the difference in the pulse frequency, similar to that shown by Fig. 2C. The Specification contains proofs of formulµ by means of which the fluid velocity can be calculated using f 1 +f 2  and f 1 -f 2 . The transducers 1 and 7, made of quartz or barium titanate ceramic or in the form of magnetostrictive vibrators, are associated with shoes 2 and 6 made of plastics material.

Abstract: 1523782 Metronomes J M DEL CASTILLO 4 Aug 1975 [6 Aug 1974 (2) 30 Aug 1974] 32586/75 Heading G3T [Also in Division G5] An optical metronome 20 has means for successively illuminating discrete areas of a face 23 intended to receive a translucent sheet 22 marked with vertically spaced staves and with musical notation, the illuminated areas thus indicating the note to be played and its desired duration. As shown an illuminated spot 27 is produced simultaneously in each of the staves by light transmitted through optical fibres the ends of which are referenced 26. The other ends of the fibres receive light passing through a perforated plate (33), Fig. 3, 4 (not shown) which is rotated by an adjustable speed motor (31). Illumination of the fibres may alternatively be produced by lamps (46), Figs. 6, 7 (not shown) which are switched on and off in succession. In other alternatives the fibres are omitted and lamps are placed behind the metronome face, e.g. in vertical reflecting channels. The lamps are energized via a motor driven contact or via logic circuitry Figs. 14, 15 (not shown) using an oscillator and frequency dividers.

Abstract: 1,138,016. Inverting. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 31 Oct., 1967 [14 July, 1967], No. 32598/67. Heading H2F. A commutating circuit for thyristor inverter bridges comprising an auxiliary bridge of controlled thyristors T1-T4, Fig. 2, with a capacitor C connected across one diagonal and with the other diagonal connected to D.C. lines 8 and 9 supplying the inverter (not shown) is characterized in that the bridge is coupled at 13 to an auxiliary D.C. source supplying a higher voltage V3, and a diode D1 blocks the charging potential from line 8. Consequently the point A is carried to a constant negative potential -V3 in the commutating cycle, and the time during which the point A remains negative is less dependent on the D.C. voltage applied to lines 8 and 9. As shown a resistance R is included between points 12 and 13. The circuit may be applied to an inverter supplying an A.C. motor from an adjustably variable D.C. source.
