Title: Aerial array processors
IPC: H01Q21/22
Filed: 1974-07-16
Abstract: 1475297 Sonar receiving system PLESSEY CO Ltd 16 July 1974 [3 Aug 1973] 37058/73 Heading G1G [Also in Division H4] A radiant energy transducer array processor comprises signal subtraction means receiving one input signal from a main array and another input signal which is the aggregate of a plurality of individually weighted signals from an auxiliary array means. The said subtraction means provides a difference signal which controls the degree of weighting applied to each signal from the auxiliary array means. The degrees of weighting are also controlled by arranging that they have an algebraic sum which is substantially zero. As described, signals from the elements of a main array are fed via lines 1 through delay units 2 and weighting devices 3 into a summing combiner 4 to provide a signal on a line 5, which is connected to one input of a subtraction circuit 6. Part of the main array is also used as an auxiliary array means, signals from three centrally located elements being fed on lines 8, 9, 10 via respective adjustable weighting circuits 11, 12, 13 into a summing combiner 14, which is connected by a line 7 to the other input of the subtraction circuit 6. An output signal on a line 15, and a feedback signal for a primary feedback loop on a line 16, are provided by the subtraction circuit 6. The feedback signal is applied to multipliers 17, 18, 19, which are also fed with the auxiliary array signals on the lines 8, 9, 10. The output signals from the multipliers 17, 18, 19 are fed to integrators 20, 21, 22, each comprising an amplifier shunted by a capacitor, which provide control signals for the adjustable weighting circuits 11, 12, 13. In order to produce a wide-band null in the direction of the main beam, the weights 11, 12, 13 are constrained to sum algebraically to zero by means of a secondary feedback loop in which voltages from each integrator proportional to the weight of its associated weighting circuit are combined on a line 23, and are fed to a differential amplifier 24. A secondary feedback voltage provided by the amplifier 24 is fed to the integrators 20, 21, 22 so that in operation said secondary feedback voltage tends to reduce towards zero. In an alternative arrangement, the auxiliary array means is constituted by an array which is separate from the main array. The processor is particularly applicable to sonar systems, but may also be applied to radar systems.

Patent GB-371788-A (GB)
Abstract: 371,788. Cables. SOC. ITALIANA PIRELLI, 21, Via Fabio Filzi, Milan, Italy. Feb. 4, 1932, No. 3364. Convention date, Feb. 5, 1931. [Class 36.] Means for regulating the pressure in an oilfilled cable A, Fig. 1, comprises a closed pressure-reservoir S connected to the cable by a pipe B in which is disposed a pump P adapted to deliver oil from the cable to the reservoir when the pressure in the cable exceeds a predetermined value which is controlled by a valve V interposed between adjacent sections 7, 6 of a pipe connecting the oil in the reservoir with that in the cable. The pump P may be driven by an electric motor M which is supplied with current either from the cable through a transformer T, or from an external circuit provided with relay devices which render the operation of the motor dependent on the conditions of load, pressure, temperature, or tension existing in the cable. The valve V may comprise two chambers 4, 8, Fig. 2, connected respectively to the pipe sections 6, 7 and separated by a partition 10 formed with an aperture 9 normally closed by the head 1 of a valve stem 2 which is carried by a flexible diaphragm 3 closing the chamber 4. Weights 5 may be applied to the upper face of the diaphragm 3 to control the value of the minimum pressure which can exist in the cable. Pressures of lower value cause the - diaphragm 3 to flex downwards, thereby opening the aperture 9 and allowing oil to flow from the reservoir into the cable. To prevent excessive pressure being applied to the cable from the reservoir when the pump P is not in operation, a non-return valve R is provided in the pipe B. The cable and reservoir may be connected by a third pipe D containing a valve C which permits oil to flow back into the reservoir when the pump P is not running and the pressure in the cable exceeds that in the reservoir.

Abstract: 928,395. Electricity metering. WEATHERFOIL Ltd., and S. M. FORDHAM. Nov. 3, 1960 [Nov. 6, 1959], No. 37741/59. Class 37. [Also in Groups XX and XXVI] Heating apparatus comprises the combination with an air-heating unit and a fan appropriated to the unit to move air therethrough, of a device for metering the heat supplied by metering the amount of use of the fan. A counter 18 (Fig. 1) is provided on the fan shaft 17 to measure the number of revolutions of the fan 12 which is driven by a motor 11. Air enters through louvres 15 at one end of a casing 13 which contains the fan 12 and a tubular hot water heater battery 14. The warmed air is driven out by the fan 12 through louvres 16. As the fan is in use whenever heat is being used the counter 18 will give a reading approximately proportional to the energy supplied. The fan circuit is connected to a suitably calibrated electricity meter. An electric meter which measures a supply for other purposes may be connected up to the fan as well as the other supply, the circuit and meter being such and the meter so calibrated that any increase in consumption indicated by the meter which is due to the fan corresponds in value to the value of the heat supplied by circulating the air. As shown in Fig. 3 the meter is employed in conjunction with a special shunt for the fan circuit. In a modification shown in Fig. 4 the meter employed has a special coil 33 connected to the fan circuit. The coil 33 has a variable shunt resistance or tappings to adjust the relationship of its effect to that of the coil 32 for the remainder of the electricity supply.

Title: Apparatus for the reception, storage, and re-emission of positive and negative numerical values, especially for use with standard office machines
Filed: 1957-12-04
Abstract: 840,828. Digital electric calculating-apparatus. BRUNSVIGA MASCHINENWERKE A.G. Dec. 4,1957 [Dec. 13, 1956], No. 37753/57. Class 106 (1). In apparatus for storing and transmitting numerical information comprising a control unit 20, Fig. 1, and electro-mechanical accumulators 21-24, the control unit includes means for selectively rendering a chosen accumulator operative, applying numerical-value-representing electric potentials to a chosen accumulator, reading accumulated information from a chosen accumulator, and zeroizing the accumulator. In the apparatus shown, the unit 20 may select, by lines 41-44, one of four ten-digit accumulators 21-24, each digit being represented by the angular position of a drum such as 61. The unit 20 comprises electromagnetic relay circuits and stepping switches (Figs. 2a and 2b, not shown). Control signals are received on line 69 from an associated accounting machine (details not given), and digit signals are received in the form of graduated voltages on parallel lines 101-104. For entry into the selected accumulator, a stepping switch in unit 20 supplies a number of pulses corresponding to each voltage value via a corresponding line 30-39 to the stepping mechanism for an associated accumulator drum. For read-out, each drum receives the graduated digit-representing voltages on lines 50-59 and determines by its position which of these lines is coupled via the line 30- 39 to the appropriate line 101-104 leading to the accounting machine. The unit 20 may be connected also to other machines, e.g. accounting machines or typewriters, by lines 80. Lines 10-19 are employed for relay-controlled tens transfer in the accumulators. Accumulator construction.-Each accumulator drum comprises ring conductors 70-79, Fig. 4, corresponding to digits 0-9, which receive the graduated voltages on lines 50-59 respectively. The rings include staggered contacts as shown, one of which, corresponding to the drum position, completes a circuit to output line 81. Tens transfer is effected through ring 97 having a contact between digit contacts " 0 " and " 9," and zeroizing is effected through ring 46 having a gap in the " 0 " position. The drum is stepped by pulsing a ratchet-and-pawl mechanism 65. For subtraction, the drum may be driven in the reverse direction by energizing relay 122 which causes wheel 121, fixed to the drum, to be driven by gear 120 in place of 119. Alternatively, the accumulator drums may be always stepped in the same direction, subtraction being effected by complementary addition. Figs. 7 and 8 show alternative constructions in which the digit rings are replaced by cams 123 or notches 124.
