Abstract: 522,578. Electrically - actuated valves. DAVEY, PAXMAN & CO., (COLCHESTER), Ltd., and PAXMAN, E. P. Dec. 9, 1938, No. 35979. [Class 135] A valve device particularly adapted for automatically controlling the supply of starting air to an internal combustion engine includes a. weighted arm adapted when released by an electrically actuated catch first to unlock a valve actuating member and secondly to actuate said member which is connected to the valve by toggle links. In the form shown in the Figure a ball 31 is normally in engagement with its seat by an adjustable spring 39 acting through sliding members 29, 36 and toggle links 27, 28. The centre joint of the toggle links is pivoted to a member 21 slidably mounted at one end in a socket 25 and at the other end provided with a flange normally engaged by a locking catch 17 mounted in a fixed pivot 18. A weighted arm 12 is secured to a boss 9 pivotally mounted on a spindle 10 supported in cheeks 11 and is normally held in an elevated position by a catch 6 co-operating with an eccentric rim 8 on the boss. The catch 6 is normally supported by a flange 5 adjustably mounted on an extension 3 of the core of a solenoid 2. When the solenoid operates, the flange 5 is withdrawn and the catch 6 falls or is moved by the flange 4 to release the pin 8. As the weighted arm falls a projection 15 on the boss first releases the locking catch and afterwards a second projection 16 on the boss engages a pin 24 connecting a pair of links rotatably mounted on the shaft 10 and pinned at 23 to the member 21 to move this member to the left and so break the toggle. In a modification the abutment 38 has a lost motion connection with a spindle adapted to actuate a second valve. The member 21 may also be modified to actuate a valve.

Title: Improvements in transmission-line reflectometers

Abstract: 1, 070, 370. Measuring the modulus of the reflection coefficient of transmission lines. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 23, 1965 [Aug. 26, 1964], No.36058/65. Heading G1U. The modulus |R| of the reflection coefficient R of a reflection point E in a high-frequency transmission line T, such as a coaxial line or waveguide, is determined by an arrangement comprising a radio-frequency generator H the frequency of which can be varied periodically by means such as an auxiliary generator W so as to vary the wavelength of energy propagating along the line. Two detectors G1, G2 are connected to the transmission line at points C, D at a distance from point E which is equivalent to a large number of wavelengths e.g. 50 or more. Detectors G1 G2 are spaced along the line by a distance of substantially one quarter of the mean line-wavelength # 0 . Direct voltages from detectors G1, G2 are applied to the ends of a potentiometer R1 - R2 the tapping F of which is connected to an indicator M. It is shown in the Specification that the modulus |R| of the reflection coefficient is proportional to the difference between the output voltages of detectors G1, G2. The modulus |R| can thus be measured by measuring the peak amplitude of the alternating voltage appearing at the point F as the frequency of generator H is cyclically varied. As shown detectors G1, G2 are connected in opposite directions so that their output voltages are operative in opposite senses at tapping F. Alternatively, detectors G1, G2 may be connected in the same direction and their outputs applied to a pushpull balanced input of a cathode ray oscilloscope which may indicate the modulus variation with variations in frequency. The amplitude of the generator output voltage may be kept constant as the frequency varies by a detector G3 connected at a point A which is isolated at S from the reflected wave. An artificial reflection is producted at B which is “ # 0  from point A and serves, when the frequency variation of generator H is large to reduce errors.
