Abstract: 1320294 Aerials AMPEXCORP 7 Feb 1972 [24 Feb 1971] 5520/72 Heading H4A An aerial assembly comprises an elongate conductive supporting structure 10, such as a vertically disposed tubular mast section, on which are mounted one or more bays 12 each consisting of two aerial elements 14a, 14b, having respective signal feeding means, and at least one director associated with at least one of said elements. Each director comprises a plurality of planar members 22, which are spaced along its axis, and are normal thereto. The directors are disposed so that they do not interest the radiation axis 16a or 16b of their associated element 14a or 14b and so that they cause overlapping of the radiation patterns of said elements. As described, two aerial arrays, on opposite sides of the mast section 10, are formed by a plurality of bays 12-1 to 12-5, which are mounted one above the other. The diameter of the mast section 10 is at least a quarter wavelength at the mean frequency of operation of the arrays. Each driven aerial element comprises a vertical slot, such as the slot 28 shown in the bay 12-2, behind which is a cavity 30, and which is fed by a respective array transmission line 48a or 48b. A dielectric cover 32 is placed over each slot. Mounted on each cavity 30 are two brackets 34, one on each side of the slot 28, from which extend director support rods 36, rearwardly and outwardly. Mounted on each rod 36 are planar members 22, which may be plates or discs, of solid or skeleton construction. Said members 22 have their respective major dimensions at least quarter wavelengths at the mean frequency of operation of the associated array. The two arrays, which may be staggered vertically by about a wavelength at their mean frequency of operation, have respective substantially omnidirectional radiation patterns 24, 26 and, since their is no significant coupling between the arrays, one may be used for the video transmission of a TV channel and the other for the sound transmission thereof. Another use would be for the arrays to transmit respective different complete TV channels.

Abstract: 1,046,075. Valves. CONCENTRIC (ENGINEERING) Ltd. Feb. 4, 1965 [Feb. 12, 1964], No. 5795/64. Heading F2V. A valve for controlling the flow of hydraulic fluid comprises a spool 11 movable between different positions in which flow through the valve in different ways is possible has a ramp 9 on the spool to actuate a flow control valve 42, 47. When the spool is moved to the left from the position shown, the waisted portion 12 occupies the position 23 disconnecting the inlet 13 from an outlet 15 and a valve 42 is lifted by the increase in pressure to connect the inlet 13 to a supply port 14 for an apparatus controlled by the valve. On the supply pressure reaching a predetermined value, a spring-loaded valve 33 connects the space surrounding the waisted portion with the outlet 15 by way of passages 35 and 39. When the spool is moved to the right, the ramp first lifts a valve 42 and then the valve 47 to give a progressively increased rate of discharge from the apparatus through the port 14. Grooves in the spool engage a spring-loaded roller in the end positions while a spring 25 biases the spool to its central position. If pressure inside the valve builds up due to the operator holding the valve in the supply position too long, the internal space is increased by movement of a spring-loaded piston 41a.

Abstract: 589,834. Electrostatic pick-up circuits. RADIO CORPORATION OF AMERICA. March 12, 1945, No. 6195. Convention date, March 29, 1944. [Class 40 (iv)] [Also in Group XL] In a signal-translating device suitable for gramophone record reproduction in which the responses of two tuned circuits to a common applied frequency are varied in opposite senses by a common movable tuning member, the circuit voltages are applied to two rectifiers having a common load, so as to obtain a voltage proportional to the tuning member movement. The Figure shows an arrangement in which the common frequency is obtained from a crystalcontrolled oscillator whose anode circuit, comprising inductor 5 and coupling windings 6 and 7 is tuned to resonance by the capacitor 8. The resonant circuits 17, 27 and 23, 28 are both tuned to a frequency slightly different from the applied frequency when the earthed centre plate 30 of the double capacitor is equidistant from the fixed plates. Movement of 30 from this position, however, causes the voltage across one circuit to decrease, while that across the other increases, so that the diode outputs, which are of opposite polarity, no longer cancel, giving rise to a resultant voltage in the load resistor 21. Resistors 20 and 25 determine the " Q's " of the resonant circuits. The plate 30 may be connected to a pick-up stylus.
