Abstract: 606,500. Radio navigation. COOPER M, F. Sept. 21, 1944, No. 18079. [Class 40 (vii)] In a direction-indicating receiving apparatus for use with a rotating equi-signal beacon, the time - base of a cathode - ray oscilloscope is controlled by a synchronizing signal, radiated omni - directionally, while the lateral deflection of the trace is in accordance with the difference between the component signals of the received equi-signal. beam. Rotation or sweeping of the transmitted beam may occur through 360 degrees or any lesser angle, and Fig. 1 (not shown) illustrates a suitable transmitter. In the receiver, Fig. 2, the signals, comprising the two components of radiation which form the equi-signal beam pass through a receiver R and amplifier A and are separated out in a separator circuit S whence they are fed separately to a differential circuit D. The circuit D may comprise a thermionic bridge giving the difference of the component signals. The output of the circuit D is fed to the Y-plates of a cathode-ray tube CRT. The output of the receiver R which includes the synchronizing signals is also fed to the filter F which accepts the latter and passes them to a time-base generator TB which provides the horizontal deflection in the cathode-ray tube. Fig. 3 shows the resulting display, the trace crossing the horizontal zero axis when the equi-signal zone of the radiation crosses the receiver location. G, Fig. 2, is a circuit for gating the amplifier A during the arrival of pulses in the case of a pulse transmission, thereby providing means for elimihating indirect rays and other interference. It comprises a crystal oscillator generating a sine wave which is fed via a phase-adjusting circuit to a circuit including a back-biassed valve for converting the sine wave into a pulse wave. The output of the circuit is fed to an overloaded amplifier to produce square-topped waves suitable for gating the amplifier A. The oscillator is normally tuned to the P.R.F. of the transmission, manual adjustment also being provided. The system is said to be applicable for use with transmission at a constant carrier frequency or with panoramic transmission. Specification 438,446 is referred to in the Provisional Specification.

Filed: 1948-07-09
Abstract: 653,115. Pyrophoric lighters. DEHN, S. G. (Miller Liter Co.). July 9, 1948, No. 18523. [Class 75(iii)] The wadding chamber 36 and fuel tank 12 of a pyrophoric lighter are connected by a passage 20, at one end of which a valve 30 is manually operable to allow fuel to flow into the wadding chamber. The fuel tank 12 is filled on removal of a cap screw 18. A cylindrical bore 20, Fig. 4, extending to the top 22 of the transparent casing 10, houses a spring-loaded plunger 24, the upper end 35 of which is engaged by a pivoted snuffer-arm 26, while the lower end carries a valve 30 normally held by the plunger spring 32 against a flared seat 28 at the base of the bore 20. The filling 42 of the chamber 36 extends round the plunger 24 to prevent fuel escaping through the upper part of the bore 20. In the closed, half-open or fully open positions of the arm 26 the valve 30 is closed, but as the arm is raised first a corner 56 and then, if the arm is turned to the dot-and-dash position of Fig. 4, a corner 58 at the rear of the arm acts on the plunger 24 to open the valve, so that the fuel which will have collected on the valve 30 can pass by capillary action to the bore 20 and thence to the filling 42. If the wick requires more fuel, the arm 26 is positioned so that the valve 30 is opened, a spring-loaded pin bearing on the arm 26 holding the latter in any set position, and the lighter is then tilted so that fuel can flow from the tank to the chamber 20. In a modification (Fig. 8, not shown), the cylindrical bore lies transversely of the casing, crossing a downward extension of the wadding chamber and opening on to a side wall of the casing ; a disc-shaped valve integral with the plunger has a bevelled inner face which normally seats against a resilient washer in the enlarged inner end of the bore. To re-fuel the wadding chamber the enlarged head of the plunger, housed in the enlarged outer end of the bore, is pressed in to open the valve and the lighter is tilted.
