Title: Improvements in or relating to echo sounders and like sub-aqueous pressure wave apparatus
IPC: G01S1/72
Filed: 1946-05-23
Abstract: 626,309. Subaqueous audible and like signalling apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and TWATT, J. May 23, 1946, No. 15697. [Class 118 (ii)] In a subaqueous echo-sounding or like apparatus of the pulsed transmission magneto - strictive type employing a combined transmitting-receiving element, the electrical receiver is protected from the effect of the electrical pulses to be transmitted by means responsive to those pulses. Uni-directional pulses derived as in Specification 626,308 are applied to a magneto-strictive transducer 1 and echoes received thereby are fed by the receiver coupling transformer 14 to the grid 18 of the first valve 19 of an electrical receiver of suitable type. During the transmission of pulses an auxiliary anode 17 and cathode 5 of the triggered mercury vapour tube 20 provide a shunt path for received signals to prevent the voltage due to the transmitted pulse from damaging the electrical receiver. A choke 13 limits the transmitted energy which is fed directly into the coupling transformer 14. The magnetic circuit of the transducer 1 has no air-gap, in order that the rotentivity may be sufficient for the applied uni-directional pulses to provide the necessary degree of steady magnetization. Specification 626,310 also is referred to.

Title: Radio frequency tuner
IPC: H01F21/06
Filed: 1955-06-01
Abstract: 785,073. High-frequency impedance networks. ALADDIN INDUSTRIES, Inc. June 1, 1955 [June 21, 1954], No. 15699/55. Class 40 (8). A wide-range (e.g. 54 to 890 Mc/s.) tuner comprises a coil 2 mounted axially within a housing 10 containing a telescopic tuning member 12. The coil 2 comprises an insulating tubular support upon which is deposited a helical metallic film and a protective layer of low-loss dielectric. To obtain adequate band-spreading and to minimize losses the coil is of non-uniform inductance per unit length having, in the example shown, a higher turn density in its central portion. The left-hand end of the coil is connected by a ribbon conductor 25 to the anode of a grounded-grid valve amplifier 26. At its righthand end the coil projects through the movable tuning member 12 which is insulated from the coil by an air gap and from the housing 10 by a dielectric layer 13. A metallic tube 40 surrounds the portion of the coil projecting beyond the member 12 and ensures that this portion is ineffective. The inductance of the variable portion of the coil to the left of the member 12 is tuned by various stray circuit capacitances and presents a high resonant impedance to the anode of the valve 26. As the tuning member 12 approaches the left-hand end of the housing 10 the tuner begins to behave as a short-circuited resonant quarter-wave line. Thus the Q of the circuit is maintained at the high-frequency end of the range. The right-hand end of the coil is connected to a source 33 of anode voltage and the left-hand end to an output lead 37. Alternatively the output may be derived by means of a loop 35. The tuning member 12 is moved by a cam and lever mechanism 17, 21.

Abstract: 962,839. Pressure gauges. DUNEDIN ENGINEERING CO. Ltd. April 25, 1963 [April 26, 1962], No. 15904/62. Heading G1L. [Also in Divisions Fl and G3] Apparatus through which pressure fluid is passed from a fluctuating source to a gauge 5, and which may be used for testing engine fuel-injection equipment, has a restrictor 23 and a pressure relief 24 between the inlet 22 and a further restrictor 7, fluid from which passes to the gauge 5. Flow takes place through the restrictor 7 via sets of small-diameter radial-holes 10, an annular chamber 8 and axial bores 9. The number of radial holes 10 in each set is different. The restrictor 7 damps fluctuations in the pressure fluid, and when the latter falls e.g. on stopping the engine, the gauge gives a pressuredrop reading due to leak-back from the gauge through the restrictor.

Patent GB-1217094-A (GB)
Title: System for automatically controlling vehicle speed
IPC: F02D41/30
Filed: 1969-03-27
Abstract: 1,217,094. Automatic speed control. HITACHI Ltd. March 27, 1969. [April 10, 1968], No.16216/69. Heading G3R. The running speed of a vehicle is automatically maintained at a desired value memorized from the output of a tachogenerator 68. The speed of the vehicle is controlled by a throttle valve Figs. 1,4 (not shown) driven through an electromagnetic clutch by a servomotor 21. The servomotor 21 is energized, forward or reverse, according to the out-of-balance signal from a bridge circuit serving as a comparator and comprising two resistors 41, 44 and two field effect transistors 39, 40; the conduction of the transistors 39,40 depends upon the voltages on two capacitors 85, 91. The output of the tachogenerator 68, detecting actual vehicle speed, is partially differentiated by a network 82, 83 and applied through a potential divider 75 to the capacitor 85 and through a normally closed relay contact 86 to capacitor 91 so that during manual control of the vehicle equal voltages are applied to the two F.E.T.'s 39,40, the bridge is balanced and the servomotor is not energized. Depression of a push button 15 engages the automatic control by energizing a relay 20 which closes a self holding contact 33 and opens the contact 86. The voltage on the capacitor 91 remains at the last value received from the tachogenerator. If the speed subsequently changes, the voltage on capacitor 85 varies unbalancing the bridge and energizing the servomotor 21 to correct the change. If, under automatic control, either the brake or clutch pedals of the vehicle are operated, a contact 32 is opened to de-energize the relay 20 so as to revert to manual control. The electromagnetic clutch is only energized under automatic control (by coil 18) so that the servomotor imposes no load on the accelerator linkage during manual control. If it is desired to reduce or increase the speed of the vehicle under automatic control pushbuttons 88, 90 may be operated to apply, respectively, voltages slightly lower or higher than that on capacitor 85 to capacitor 91 so as to unbalance the bridge and drive the servomotor until the new speed is reached. The higher and lower voltages are derived from the potential divider 75 which employs diodes 78, 80 so that the difference in voltages is fixed and the charge in speed takes place at constant acceleration. Limit switches 24, 26 prevent the servomotor 21 driving the throttle beyond its limits.

Above the trunk of the tree is a deflector means 44 comprising a deflector 46 provided with veins 48. Connection between the delivery conduit 38 and the deflector means 44 is effected by a support 56 attached at one end to a collar 42 slidably mounted on the delivery conduit.

A coupling for pipes or hoses 23, 24 comprises an outer sleeve 2 and an inner sleeve 1 each being attachable to an end of one of the pipes or hoses, the sleeves 1, 2 being a sliding fit one within the other. A peripheral groove 7 is provided in the outer periphery of the inner sleeve 1 and is positioned within the bore of the outer sleeve 2. Apertures 8 are formed through the wall of the outer sleeve 2, which apertures house balls 9 or other members such that the balls are movable radially with respect to the outer sleeve 2. A collar 10 surrounds the outer sleeve 2 and is slidable thereon, the collar 10 being provided within its bore with an annular groove 20 with which one or more radial passages 21 in the wall of the outer sleeve 2 communicate(s). The collar 10 is springloaded so as to be urged to a position permitting movement of the balls in an outward radial direction out of the peripheral groove 7 to permit operation of the sleeves. The collar 10 is, however, movable in the opposite direction by pressure fluid passing through the coupling and entering the groove 20 in the collar to cause the bore of the collar to move the balls inwardly to engage the peripheral groove 7 and thus lock the coupling. The end faces of the groove 20 are of different areas to permit movement of the collar under fluid pressure. A bellows 25 may be interposed between the ends of the pipes or hoses and the respective sleeves to urge the sleeves towards each other on fluid pressure build up in the pipes or hoses. Flared portions 3, 4 of the sleeves serve to ensure concentricity therebetween.
