IPC: G01S7/04
Filed: 1964-02-14
Abstract: 1301952 Missiles SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 14 Feb 1964 [27 Feb 1963] 6398/64 Heading F3A [Also in Division G3] A control signal for a missile is derived from a comparison of recorded information of zones over which the flight may occur with information of the zone actually followed. The area over which the flight may occur is divided into strips parallel to the direction of flight and signals corresponding to the terrain profile along each strip are stored in a magnetic drum memory. Profile signals corresponding to the actual path are stored in a second memory and the first memory is scanned until the signals derived therefrom correspond with those of the second memory. The displacement of the strip over which the missile is moving with respect to the required path is thus derived and a corresponding lateral control signal is developed. The comparison between the two sets of signals is effected in a correlation circuit comprising a multiplier and an integrator, binary notation being employed. Determination is also effected of the deviation of the missile speed relative to the speed associated with the recorded information.

Title: Methods of and apparatus for attenuating sudden pressure surges in fluid lines
IPC: F16L55/052
Filed: 1960-02-23
Abstract: 900,763. Pressure relieving devices; valves; hydraulic accumulators. EVERETT, W. S. Feb. 23, 1960, No. 6400/60. Classes 69 (2) and 135. A device for absorbing sudden increases or decreases of fluid pressure has a casing 10, Fig. 1, inside which is a gas-filled bellows 22, the upper end of which abuts a ring 19 supporting a depending liner 20 whilst the lower end is connected to a guide 23 with drain holes 26. The distended position of the bellows is defined by a ring stop 27 with flanges 28 whilst the compressed position is determined by the lower end of the liner 20. The space around the guide 23 is connected to the surge line by an inlet 31 incorporating a throttle 33 comprising spaced discs 34, 37, Fig. 2, with central apertures 35, 38, the disc 34 and aperture 38 being larger than the other disc and aperture, respectively; the discs co-operate with a bushing 32, Fig. 1, in the inlet. When a sudden pressure increase occurs the throttle 33 is urged upwardly until the disc 37 abuts the bushing 32 whereupon fluid flows through the larger aperture 38 into the casing 10 to lift the guide 23 and compress the bellows 22. As the surge dies away the bellows 22 expand and the disc 34 abuts the bushing 32 so that exhaust from the casing takes place through the smaller orifice 35 which prevents resurge into the line. If the surging fluid is water then the bellows may be dispensed with and a water-air interface relied upon. To guard against suddenly reduced pressure conditions, e.g. due to a pump failure, the throttle 33 is reversed and the inlet 31 is enlarged.

Title: Improvements in and relating to regenerative braking control systems for electric motors
IPC: H02P3/14
Filed: 1950-03-15
Abstract: 674,665. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. March 15, 1950. [March 29, 1949] No. 6510/50. Class 38 (iii). A variable voltage generator 2 has a separately-excited field winding 2a and is adapted to supply a motor 1 which drives a load having substantial inertia. In an emergency the field winding is disconnected from its supply and is connected across a non-linear resistor 6 the resistance of which increases as the voltage applied to it decreases. The field winding is thereby discharged at such a rate that the generator voltage decreases in correspondence with the regenerative voltage of the motor, the braking torque being maintained substantially at the maximum obtainable with safe armature current-values. Closure of switch 13 energizes relays 12 and 18 in sequence, contacts 8b, 8c, being respectively opened and closed. A relay 11 is then energized, and, when a push-button 9 is depressed, relay 10 closes the supply-circuit for the field winding 2a, relay 3 completing the motor armature circuit. Acceleration is effected by increasing the voltage of the supply 4, 5. When emergency stop switch 18 is actuated, contactor 8 drops to connect field winding 2a across resistor 6. Relavs 12 and 11 are deenergized, the latter being of the time-delay type, so that, after a pre-determined interval greater than that required to brake the motor, the contactor 3 drops to open the armature circuit. In a modification, Fig. 3 (not shown), when the contactor 8 is de-energized in response to the operation of the emergency switch, the generator field winding is connected in series with the non-linear resistor to a low-voltage source for reverse energization. A small reverse current during stand-by minimises residual voltage of the generator. According to Fig. 4 (not shown), during braking operation, the positive terminal of the generator field winding may be connected through the non-linear resistor to the negative terminal of the generator, the negative field and positive armature terminals being connected. The non-linear resistor may take the form of a dry contact rectifier, of the selanium or copper oxide type, which is connected in series with a fixed resistor, Fig. 5 (not shown). The rectifier is permanently connected across the generator field winding and is poled to be non-conducting when the winding is connected to its separate excitation source. Specification 292,110, [Class 38 (ii)], is referred to.

Filed: 1940-04-11
Abstract: 565,115. Gun mountings. BRITISH POWER BOAT CO., Ltd., and SELMAN, G. S. April 11, 1940, No. 6600. [Class 92 (i)] Relates to gun mountings of the " ring " type in which the gun is universally jointed to the upper end of a support 30, the lower end of which is so connected with the rotatable ring that the joint can be adjusted, in a plane parallel with the ring, to position it either inside or outside the ring. According to the invention, means, preferably remotely controlled, are provided for locking the support to suit either of the two positions of the joint. In the form shown, a socket 29 attached to the rotary ring supports on a vertical pivot 31 a cranked bracket 30 in the upper part of which is provided a socket for a vertical pin 35 on a cross-piece 41 on which two guns are freely trunnioned by yokes 42. Fig. 1 shows the bracket adjusted to the position for high-angle fire, or for stowing the gun by cables 51. By operating a Bowden cable 49 from a lever on the gun butt, a detent 47 is released to enable the bracket to be turned in the socket 29 through 180 degrees to bring the gun trunnions outside the ring to provide more space within the cockpit for depressional movements of the gun. Training is facilitated by a depending shoulder arm 57 on the rotary ring. Fig. 4 shows the ball race for the rotary ring 19 provided with grease and dirt-proof leather strips 23, 24 and a screw-operated fastening 26 for locking the ring when out of use.

Filed: 1928-03-03
Abstract: 286,317. Quarzlampen-Ges. March 4, 1927, [Convention date]. Low-pressure metallic-vapour apparatus.-Mercury-vapour quartz lamps have the pole vessels at both ends of the arc tube connected to the tube by tubular connections of smaller inner diameter than the arc tube. A direct-current lamp which can be connected either way to the supply has one pole vessel at each end of the arc tube L, Fig. 1, the pole vessels and capillary connections M being of the same size. During operation, the connection M at the cathode K is half filled with mercury and the connection M at the anode A is empty, a minute vapour chamber B forming at the anode A as shown. An alternating-current lamp has an arc tube L, Fig. 4, with a cathode K at one end and two anodes branched at the ether end, separate capillary connections A<1>, A<2> leading from the end of the tube L to the anode vessels and 'being closed by mercury at the lower ends as shown. To prevent back ignitions, each anode vessel has a condensing chamber, these chambers C<1>, C<2> being connected to the tube L by separate tubes D<1>, D<2> which are preferably straight and sloped so that mercury condensed in them flows back to the chambers C', C<2>. Anode currents passing through the tubes D<1>, D<2> during the period following ignition do not disturb the operation of the lamp. The lamps can be operated at current below 1 amp. The capillary connections prevent movement of the mercury when the lamp is tilted. The quantities of mercury in the pole-vessels are equal in the direct-current lamp and are. small in the case of the anodes of the alternating-current lamp, which is started by emptying the cathode pole-vessel.

Liquid-level pressure gauges, indicating-means for. - A differential gauge for use with fluidvelocity meters wherein a pressure-differencecreating device located in the conduit through which the liquid flows is connected to the pressure gauge, comprises a float-well 6 and an annular well 8 both containing mercury, a float A comprising a cup 10 containing mercury, a supporting- member 11 and a displacing portion 9 which is shaped so that equal vertical movements of the float A represent equal changes in the rate of flow, thus enabling the indicators to be given on a uniform scale instrument. The mercury in the well 8 is connected with, that in the cup 10 by means of an inverted U-tube 12 also filled with mercury and the relative areas of the well 8 and cup 10 are arranged as circumstances require so that the indicators fall within the range of the pressure differences to be observed. The mercury in the annular well 8 is subjected to the leading pressure from a pipe L connected to the pressuredifference-creating device, and that in cup 10 to the trailing pressure through pipe T. Movement of the float A causes an upward or downward motion of a rod 15 which by mechanism rotates a permanent magnet 23 which operates in known manner an indicating pointer' 28 moving over a scale 31 or actuating recording mechanism. In a modification, the annular well 8 is replaced by an external cup member similarly connected. In either form, a fixed piston member may be added inside the cup 10 in order to ensure ready response of the cup member to variations in the pressure.

Abstract: 402,842. Automatic circuit-breakers and retractive switches. DAVEY, W. C., 176, Tottenham Court Road, London. Feb. 25, 1933, No. 6966/32. [Class 38 (v).] In a signalling apparatus the calling switch is operated by a handle 1 attached to a pivoted lever, the handle when depressed causing a pin 3 to bring contact springs 4 into engagement, so energising a yieldably-mounted electromagnet 6 to attract an armature 5 attached to the pivoted switching lever which is thereby retained in the "on" position. The circuit completed at contact springs 5 also includes an indicating lamp 8 at the receiving station and the circuit may be broken at this station by depression of a transparent push button 9 acting as a lens for the lamp which moves down an insulating rod 14 to separate a contact spring 12 from one of the lamp terminals. On depression of this push-button the electromagnet 6 is de-energized and the calling-switch automatically returned to the " off " position. Alternately, the signalling circuit may be broken at the calling station by backward movement of the calling switch handle 1. A single-stroke bell may also be placed at the receiving station, to be energised simultaneously with the indicating lamp and further strokes of the bell may be given by continued depressions of the operating lever 1 which moves the contact spring 17 on which the electromagnet 6 is supported away from the contact 18 also included in the signalling circuit. Instead of mounting the armature directly on the switch lever it may be so arranged that when attracted it operates a catch to retain the calling-switch lever in the depressed position, the catch being however, of such a nature that the lever can be disengaged from it by hand.
