Title: Ship's emergency steering by means of submersible towed bodies
IPC: B63H25/52
Filed: 1920-08-17
Abstract: 171,932. Law, C. Aug. 17, 1920. Steering by submersible towed bodies; towing. -Consists in using submersible towed bodies such as paravanes in pairs for emergency steering of ships, each towed body having either one or two towing-wires. When one wire H,.Fig. 3<B>, is used for each paravane, steering is effected by hauling in one wire on the port or starboard side and paying out the wire of the paravane on the other side. When two wires H, J, Fig. 5, are employed, they are attached to the points F, G, Fig. 2, of the paravane. The port and starboard wires J are of equal length and are attached at fixed points to the ship, whereas the wires H are led inboard to the main steering chains, or to a winding medium, such as a winch, so as to be adjustable relatively for steering. More than one pair of towed bodies mav be employed.

Title: Improvements in and relating to multi-channel pulse signalling systems
IPC: H04J3/00
Filed: 1947-02-14
Abstract: 624,034. Multiflex pulse signalling. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. Feb. 14, 1947, No. 4353. [Class 40 (v)] In a multi-channel pulse signalling system adjacent transmitted pulses are of different carrier frequency. Fig. 1 shows a pulsetiming oscillator PTO of frequency equal to one half of the overall pulse recurrence frequency controlling a two-channel distributermodulator DM generating pulses and a frequency modulated oscillator FMO with doubler FD, modulated pulses of alternate radio frequencies f1 and f2 being produced at M and amplified at RFA. The oscillations of PTO may be sinusoidal if the pulses are amplitude modulated, or, if the pulses are phase or width modulated, of squared waveform. Fig. 2 (not shown), shows separate oscillators O1, O2 feeding gate valves V1, V2, opened alternately by injected oscillations from a transformer TR. To produce more than two radio frequencies a saw-tooth waveform of frequency equal to or a multiple of the channel recurrence frequency may be used, and stepped to provide a constant frequency over each channel width. Fig. 3 shows a receiver having a synchronizing signal selector SS controlling an oscillator PTO, controlling respectively a channel distributer CD and a frequency-modulated oscillator FMO and doubler FD so that oscillations varying synchronously with but differing from the transmitted frequencies are produced in a mixer MR and a constant IF results. Alternatively two different IF amplifiers with a common or separate local oscillator may be used. If the frequency of variation of the signals is not a multiple or sub-multiple of the channel recurrence frequency a pilot signal having a multiple frequency may be transmitted with the pulses.

Filed: 1976-02-05
Abstract: 1533749 Controlling seismic generators SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 5 Feb 1976 04576/76 Heading G1G The firing time of a siesmic generator is controlled by adjusting a time delay between a command signal F and the closure of a switch 23 actuating the generator in accordance with the time lapse between a command signal F and the detection of a change in an electric parameter of the firing circuit arranged to be affected by a physical change of or in the seismic generator accompanying the generation of a seismic pulse. In Fig. 1, two air gun seismic generators 1, 2 are fired by energizing a solenoid 7 to raise spool valve 6 to release air under pressure into surrounding water. As the valve rises the pressure in chamber 4 and line 10 increases to a maximum value, detected by bellows 18 to connect resistance 19 across the two-conductor cable 22. A detector 28 responds causing a comparator 27 to compare a time code generated at 25 with a predetermined time code input at 29 and make any necessary adjustment to a delay coder 26. A second comparator 24 closes switch 23 when the time code generated at 25 equals the delay code in 26. The predetermined delays input at 29, 29 may be equal or different as desired. More than two seismic generators may be employed and different types, e.g. gas exploders and steam guns may be used. A Piezo-electric transducer may replace bellows 18 or an accelerometer may be mounted on the generator housing to detect the seismic pulse, or the position of the valve 6 may be detected.

Title: Improvements in or relating to aircraft fuel systems
IPC: B64D37/00
Filed: 1954-02-17
Abstract: 766,447. Filling tanks. SELF-PRIMING PUMP & ENGINEERING CO., Ltd., and STEVENS, G. C. Feb. 17, 1955 [Feb. 17, 1954], No. 4706/54. Class 21. An arrangement for filling a fuel tank in a system wherein a booster pump 20, Fig. 1, in or adjacent the tank pumps fuel out through pipes 21 and 22, comprises an opening 26 in the pipe 22 leading to the inside of the.tank, and a two position valve 32 which closes the opening 26, as shown in broken lines, in response to the output pressure of the booster pump when fuel is pumped from the tank but which, when the booster pump is stopped and the tank is being filled through the pipe 22, is biased to a position shown in full lines, closing the flow path through the pump 20 and pipe 21 to permit the incoming fuel to pass into the tank through the opening 26. The valve 32 is biased to the position, shown by the spring 35 but according to a modification the opening 26 extends from the upper face of the pipe 22 and the valve 32 is then hinged at its upper end so that it may be normally biased downwardly by gravity to close the pipes 20 and 21. If the opening 26 is in the upper face of the pipe 22 it is coupled to a conduit terminating near the base of the tank. In Figs. 6 and 7, the fuel extracted from the tank by the pump 70 causes the valve 80 to rise and close the pipe 79 and the fuel then passes away through an outlet 73. When the tank is to be filled, the pump 70 is stopped and the valve 80 falls under gravity to close the pump 70 and permit the fuel entering through the pipe 73 to flow through the pipe 79 past a oneway valve 87 to a pipe 83 terminating in a float operated shut-off valve 86 near the top of the tank. When the tank is filled, the floatoperated shut-off valve 86 closes and the input of fuel is then'stopped. If the fuel is drawn off without the use of the pump 70 the valve 88 opens. Specifications 670,226, 697,749, 713,845, 731,671 and 731,672 [all in Group XXVI] are referred to.

Abstract: 216,099. Snead & Co., (Assignees of Macdonald, A. S., Huggins, E. M., and Waite, C. C.). May 16, 1923, [Convention date]. Alarms operated by expansion of solids. - An electric apparatus for heating metal bars P and the like comprises longitudinally adjustable clamps 10, 11 carried by horizontal supports 12 and means actuated by the expansion of the bar for indicating its temperature, the clamp 11 being mounted on a carriage 25 which moves automatically to take up the expansion of the bar. The carriage 25 is provided with vertical and horizontal rollers 27, 28, engaging fixed guideways 26. A cord 32 secured to a lug 31 on the carriage passes over a drum 33 mounted thereon to a counterweight 30 which keeps the bar in tension. The carriage can be returned to its original position by a treadle 36, a spring bolt 75 engaging a fixed bush 76 when the original position is reached. The clamps 10, 11 are provided with jaws 40, 41, the lower jaws 41 being operated to grip the bar by solenoids 54 acting against springs 57. The cores of the solenoids are in two parts 59, 61, the part 61 being secured to the jaws. The supply leads 45 are connected to the bodies of the clamps, the latter being connected to the lower jaws by laminated flexible conductors 52. The heating current is supplied by a transformer T, Fig. 7. Rotation of a handoperated cam 80 raises the bolt 75 and closes the switch 79 with consequent closure of a switch X to complete the circuit through the solenoids 54 from the mains D. Further rotation of the cam closes the switch 78 to complete the primary circuit of the transformer T. Movement of the carriage 25 to take up the expansion of the bar P causes rotation through rack and pinion gearing of a member 70 moving over a graduated dial and carrying a contact 72. When the expansion has reached a predetermined amount, the contact 72 engages the contact 73 with consequent closure of a switch B to open the primary circuit of the transformer and close a circuit containing an .alarm bell N and a lamp, N<1>. A relay switch Y, operated by a switch 63 connected to one of the jaws 41, is closed only when the jaws are open so as to ensure a high initial current through the solenoids, and is arranged in shunt to a resist. ance Z which is sufficiently large to prevent overheating of the solenoids when the jaws are closed.
