Title: Improvements in or relating to radio direction finding systems
IPC: G01S1/02
Filed: 1941-09-25
Abstract: 581,806. Radio direction-finding; radiolocation. AGATE, C. S., and COOPER, A. H. Sept. 25, 1941, No. 12412. [Class 40 (v)] A wireless direction-finder comprises two rotatable directional aerials 2, 3, angularly displaced from each other, and means for applying to a visual indicator, such as a cathode-ray tube, signals which are the difference between signals representing the rectified sum and the rectified difference of the signals received by the aerials, in such a manner that an indication is given only if the signals received by the separate aerials are substantially equal in intensity. The respective signals pass through amplifiers 11, 12 to a transformer 13 having two pairs of secondary windings, so connected that signals representing the rectified sum and the rectified difference are produced in the load resistances 14a, 15a respectively, connected to the grid and cathode of the cathode-ray tube 10. The aerials 2, 3 and a transmitting aerial 1 may be driven by a polyphase motor 5 connected to supply line 6 which also supplies current to rotate the electron beam in synchronism with the rotating aerial. The control grid is biassed so that the electron beam is normally suppressed, but this bias is overcome by the positive potential across 14a, 15a when the signals from the two aerials are substantially equal. In a modified system, Fig. 3 (not shown), the signals from the two aerials are amplified by a common amplifier, connected alternately to the two aerials by two rectifiers made operative in turn at a high frequency by bias potentials from a local oscillator. In order to indicate also the range of a reflecting object, a transmitting aerial 1 rotated with the aerials 2, 3 is energized by transmitter 7 modulated by pulses from the pulse-generator 8, which also supplies a radial component of scan to the tube 10, so that the beam is deflected radially between the transmission of each pulse and the reception of the reflected signal by an amount which depends upon the range of the object.

Convention date, April 25, 1929. [Class 87 (ii).] The explosion chambers for H.T. oil-break electric switches are formed of successive layers of a fibrous material such as paper impregnated with a resinous condensation product which are applied to the sides of a dummy having the approximate form of the interior of the explosion chamber member, portions of the layers being formed over the end of the dummy to make the bottom of the member and the resulting structure is subjected to the simultaneous application of heat and compressive forces against its opposite faces. The explosion chamber 1, which in its finished form is shown in section in Fig. 2, is formed of successive segmental layers of impregnated paper 2, as shown in Fig. 3, which are wound around a dummy 6 and have their edges slitted as shown. The layers are finally kept in position by a securing tape 40 and are then placed in position in the mould shown in Fig. 5 with additional rings of material 41 .. 44, at the ends. The mould is of conical formation having an outer ring 22 within which is secured a ring 23 containing a spiral groove 24 with an inlet and an outlet pipe 25 for the admission of hot water or steam, a segmental die 32 being disposed within. The upper movable pressure member similarly comprises an inner member' secured to the frame 15 and having a spiral groove 29 fed through inlet and outlet pipe 30, the member 28 being secured to an inner die member 27. The laminations are held in position around this die member by centring piece 35 suspended from the frame, the fringed ends of the laminations being suitably formed over the end of the die. Simultaneous heat and pressure are then applied to the laminations of insulating material which are so formed and are of such quantity that in their final compressed position they just fill the surface between the die members and bind together in a solid mass so that after cooling a finished explosion chamber of the form shown in Fig. 2 may be removed from the mould.

Abstract: 419,300. Snap-action switches; distribution boards. HOPE, V., Upton Hall, Macclesfield, Cheshire. May 6, 1933, No. 13233. [Class 38 (v).] In a tandem double pole switch adapted to be mounted on a board or box with its blades 10 and operating handle 7 in line with its fuses, the blades 10 have arms 17, 171 coupled by a link 18 and the arm 171 is also connected by a link 20 with a stud 21 on a sector-shaped plate 22 loosely mounted on a fixed stud 23 which also forms the pivot for the handle 7. The handle 7 has projections 26<a>, 27<a> adapted to engage opposite sides of the sector 22 to close and open the switch respectively. A spiral spring 28 coiled round the stud 23 with its two arms engaging respectively the stud 21 and the arm 26 of the handle 7, serves to give a quick break to the switch, the movement of the handle to open the switch serving at first merely to stress the spring 28. The projection 27<a> then engages the sector 22 and forces this to move together with the links and the blades 10. Springs 16 acting on the blades 10 also assist the break. Numbers of these switches are adapted to be mounted side by side on a board and troughs are formed between the switch bases into which the conductors pass. The switch bases themselves are trough shaped but recesses are formed in the wall at one side of the base to allow the conductors to enter.
