Abstract: 750,615. Valves. PERMUTIT CO., Ltd. April 2, 1954 [April 15, 1953], No. 10318/53. Class 135. In a rotary disc valve for controlling the flow of water through a water softener, a valve disc 48, Fig. 3, rotatable by an operating spindle 64 through a pin-and-slot connection 70, 72 selectively controls ports 8, 10, 12, 14, 16, Fig. 2, in a valve base 2 having a rubber seating gasket 6 and is held on its seat when in its selected position solely by the pressure of hard water supplied through an inlet connection 42, Fig. 2, branch 44 and a port 46 controlled by an enlarged diameter portion 62 of the spindle 64. The spindle 64 is movable axially with respect to the disc 48 by means of the lost-motion between the pin 70 and slot 72. To move the disc from one selected position to another, the spindle is raised to take up the lost-motion thus closing the port 46 and opening a leakage groove 88 leading to a drain port 30 to relieve pressure behind the disc. The disc 48 can then be easily raised by the engagement of the bottom of the slot with the pin, whence a pin 78 is disengaged from one of a series of holes 80 locating the disc in its various settings to permit rotation of the disc to a new setting. On release of the knob 60, water pressure acting on a shoulder 90 of the spindle urges the spindle 64 downwards to open the port 46 and again subject the disc to water pressure to hold it against the gasket 6. Passages 52 and 50 through which water passes bridge the various ports in the valve base 2. To exclude grit during the rinsing operation a passage 54, Fig. 5, is formed with an opening 56 leading into a groove 58 on the periphery of the disc, the clearance between the disc and the body being less than the opening 56. Markings on the knob 60 co-operate with an index mark on the valve body to indicate the valve settings. An adjustable plug 20 is fitted between a brine inlet opening 18 and the port 8 to regulate the amount of brine entering the container 4.

Filed: 1947-04-21
Abstract: 638,295. Aerials. MINISTER OF SUPPLY. April 21, 1947, No. 10586. [Class 40 (vii)] An energized loop aerial is associated with at least one parasitic dipole to produce a directive pattern of radiation polarized in the plane of the loop, the dipole being so positioned in a plane parallel to that of the loop that its projection on to the loop contains a chord. In a horizontal array for use as an omnidirectional beacon, a half wavelength dipole 14 is located parallel to a quarter wavelength diameter loop 1 comprising four quadrants energized through feeders 9, and is adjustably mounted relatively to the loop axis on arms 13 so as to enable its excitation and the degree of pattern directivity to be varied. The radiation pattern is substantially cardioid in shape and rotates with motor-driven shaft 11, supporting the dipole and a counterweight 15. Feeders 9 are inclined at 45 degrees to minimize vertical polarization and interference with the dipole. Both loop and dipole may be made adjustable in dimension, and a condenser may tune the dipole. Specification 638,296 is referred to in connection with the suppression of vertically polarized radiation components which arise at high angles. Complex radiation patterns may be produced by the use of more than one dipole.

Abstract: 548,965. Remote control systems. WHITE, S. Y. Feb. 28, 1941, No. 10680/42. Convention date, Feb. 29, 1940. Divided out of 548,202. [Class 40 (i)] [Also in Group XL] Apparatus, such as an adjustable antenna, is controlled from a remote point by means of a reversible motor, the sense and extent of rotation of which is determined by means of a source of variable voltage disposed at the remote point and connected to the motor through a relay which is associated with a Wheatstone bridge disposed near the apparatus to be adjusted. Fig. 1 shows the invention applied to a mast aerial in which the exposed length of the antenna rod 76 is varied by moving a sleeve 79 up and down by means of a threaded rod 82 driven by an electric motor 83. The motor 83 is supplied through a Wheatstone bridge arrangement Fig. 6 in which one arm includes a lamp R7 whose resistance varies with current while another arm includes a rheostat R5 varied by a travelling nut 99 on the motor shaft. Across the bridge is a polarized relay PR with central off position controlling field coils FC, FC2 for driving the motor in opposite directions. The bridge is supplied through line 86 with a voltage which varies with the tuning through the medium of a potentiometer Rl coupled to the tuning knob 45. Thus, the motor runs until the bridge is balanced by adjustment of R5. Relay PR then opens the circuit and the antenna remains adjusted in accordance with the tuning. A modification is also described comprising two horizontal dipoles at right angles on a mast, in which adjustment of all four elements is effected simultaneously by a single motor through bevel gearing (Figs. 7-9 not shown). Specification 548,202 is referred to.
