Patent GB-124577-A (GB)
Title: Improvements in and connected with Interlocking Mechanism particularly applicable to Electric Switches.
Inventor: MIDDLETON VICTOR GEORGE
IPC: H01R13/707
Filed: 1918-03-27
Abstract: 124,577. Middleton, V. G., and Baker, C. J. March 27, 1918. Plug connectors combined with electric switches. In a combined plug connector and switch in which the switch cannot be closed until the plug is in its socket, and the plug cannot be withdrawn until the switch is opened, the insertion of the plug releases the switch by means of a pivoted member which operates effectively only when pressed upon at more than one point, the pivoted member being difficult of access, so that only the plug may reach and operate it. The switch is locked by means of a pawl normally engaging a notched disk with rotates with the switch movement, whilst a cam on the switch presses a pin into engagement with the plug when the switch is closed, so as to prevent withdrawal of the plug. The switch cannot be opened unless the plug remains fully pressed home. In the construction shown, a rotary snap-action switch is arranged in the upper part of the casing separated by a partition from the plug socket in the lower part. A disk 12. fixed to the switch spindle 13, has four notches 16 engaged by spring pawls 15, 17. The pawl 15 serves only to prevent rotation in an anti-clockwise direction. The pawl 17, which normally prevents rotation in the opposite direction, has a projection 20 engaged by a rod 18 sliding in a gland 19. The rod 18 has a transverse pin 21 engaging a slot in a crank-arm 23 formed at the end of a horizontal spindle 24, which by the action of a coiled spring 25 tends to keep the rod 18 in its upper position and the switch locked. When the plug 6 is inserted, an annular projection 8 engages an H-shaped push-piece 26, Fig. 4, attached to another crank 27 on the spindle 24, thereby rotating this spindle so as to permit the rod 18 to move downwards and unlock the switch. The push-piece 26 is pivoted so that when pressed upon at one point only, as by a pencil. it rotates idly on its pivot and does not unlock the switch. The switch is assumed to be closed and opened by successive movements of 90 degrees in the same direction. In order to lock the plug, cams 28, 29, Figs. 1 and 2, engage rollers 30, 31 carried by a spring-supported plunger 32, the lower end of which enters a slot 34 in the projection 8 of the plug, when the major axis of the cams is vertical, as described in Specification 124,703. The plug 6 may be secured in position by links 35, 36, Fig. 4, and a handled toggle 37, which can be turned to force the plug against its seating 4. A padlock may be fastened through the hole 38. If the toggle 37 is released while the switch is closed, the spring 25 presses the plug out sufficiently to bring the locking-mechanism 23, 18, 17 into action, so that the switch cannot be opened nntilthe casing is again fully closed.

Title: Electron discharge device
IPC: H01J25/04
Filed: 1942-04-29
Abstract: 579,234. Discharge apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. (Radio Corporation of America). April 29, 1942, No. 5780. [Classes 39 (i) and 40 (v)] In an ultra-high frequency electron discharge device, the transit time loading between the cathode 15, Fig. 11, and control grid 21 is neutralized by taking off power between the control grid and a further electrode 22 and feeding this back to the cathode - control grid impedance in the correct phase. This impedance is the coaxial line 29, 30, tuned by plunger 44, and a similar line 30 34, tuned by plunger 46, is connected between electrodes 21 and 22. The feed-back is accomplished by rotatable loop 50 coupled to both lines. Modulating voltage is applied to the control grid by input line 52 and the energy of the modulated beam is delivered to a toroidal resonator 13, tuned by plunger 47, and connected across the gap between electrode 22 and a further electrode 23. The spent electrons are collected by a water cooled anode 25. The coaxial lines may be replaced by concentric-line resonators of toroidal form and a suppressor grid may be associated with the anode. The tuning plungers may move axially, instead of radially, as shown. The coupling loop may be L-shaped, or may be dispensed with and the electrode capacities relied on for coupling. The cathode 15 is shown heated by electron-bombardment from a filament 16, but conduction heating may be used. In one form, the cathode is a number of parallel strips 160, Fig. 14, each co-operating with a control grid 164 and a slot 165, 166 in the walls of resonators 176, 178. The circuit diagram is illustrated in Fig. 9, in which Z1, Z2 are the impedances of the lines or resonators between cathode 15, grid 21, and screen 22 and Z0 is the impedance of the coupling loop 50. The output impedance Z is that of resonator 13 and 53 is a suppressor grid. In a modification, an impedance Z3, Fig. 10, is connected between screen 22 and the cathode instead of the control grid. Specification 541,477 is referred to.
