Filed: 1929-03-12
Abstract: 330,311. Automatic Telephone Manufacturing Co., Ltd., and Beale, C. E. March 12, 1929. Automatic exchange systems. - In a group selector the wiper switching relay also acts as a changeover relay, being energized immediately the switch is seized. The holding relav has its circuit interrupted by the impulsing relay during the directive movement of the switch and by the interrupter relay during hunting. When the switch is seized A, G and then Band H operate and A repeats the first impulse series to VM to step the switch. H is held by pulses in parallel to VM. its upper winding being shorted to make the relay slow to release. When the train finishes H falls away and rotary motion takes place due to the interaction of G and RM. When a free line is reached, H pulls up over its upper winding stopping hunting and switching the circuit through. A, B and G relapse, the slow release @ag of B being sufficient to hold H until the guarding earth is returned from the seized switch. When the call finishes H falls away allowing Z to release the switch. If all the circuits from the level tested are busy the switch moves to the 11th position operating CS. Busy tone and flash are returned to the calling subscriber, earth is connected to the test wiper to meter the call and B is placed under the direct control of A. When the calling subscriber clears A and B relapse releasing the switch.

Title: Improvements in framing for rigid airships
IPC: B64B1/00
Filed: 1919-04-04
Abstract: 139,909. Mackay, R. April 4, 1919. Aerostats; framework.-A rigid airship framework composed of thin-walled tubing reinforced by internal pressure of air or gas is constructed of circumferential and longitudinal tubes connected by cross-joints so that an equal pressure is maintained throughout the framework, means being provided to shut off any part in which a leakage may occur. Sections A of tubing are connected together at C to form circular frames, Fig. 1, the connexions C being ordinary crossjoints, Fig. 3, so as to provide for the attachment of longitudinals B, Fig. 2, to complete the framing. Radial stays D connect the circular frames to a central nave E. Cross-wires are provided in the longitudinal panels, and also additional wires to form a netting. A netting may be formed also on the radial stays D. In order to shut off a part of the framing in which a leakage occurs, a ball valve L is arranged at each cross-joint in a spherical chamber K formed at the centre of partitions J. Ports M lead from the chamber K to the four tubes connected to the joint, so that if a leakage should occur in one of the tubes, the ball is moved to shut off that tube. A gland P, Fig. 4. is provided for inserting the ball, and is fitted with a plug Q bearing on a split washer R. When it is desired to charge the framing with air or gas, the ball valves are prevented from closing the ports M by means of the plugs Q, which, after removal of the washers R, are screwed in to hold the balls in the position shown in dotted lines in Fig. 4. The charging-nozzle may be inserted at a plug Q and is made long enough to hold the ball against movement. Cylindrical gas-bags are fitted between the circular frames and laced thereto. The framing may serve as a storage for hydrogen or other gas to replenish the gas-bags, the place of the gas being taken by air forced into the framing. Two additional longitudinals are provided along the bottom of the framing, to support the keel structure, gondolas, &c.

Title: Improvements in thermionic valves
IPC: H01J19/38
Filed: 1919-04-05
Abstract: 147,252. Hesketh, B. April 5, 1919. No Patent granted (Sealing fee not paid). Thermionic relays.-The thermionic flow in an amplifying, rectifying, or frequency-doubling valve is controlled by variations of an electric field transverse to that bv which the flow is maintained. A transverse field in either direction reduces the normal flow. In the arrangement shown in Fig. 2, the valve a acts as an amplifierrectifier for wireless signals, which vary the current between the filament f and anode e by setting up a transverse alternating field between plates c, d. A leak resistance is connected between the plates c, d and filament f. If a constant normal transverse field is maintained by a battery M, Fig. 3, the valve acts as a simple amplifier, and may be used for telephonic purposes, but without the battery M the variations of the anode current have twice the frequency of the impressed alternations, so that the valve may be used as a frequency-doubling device. The plates c, d, e, Fig. 2, may be replaced by helices c1, d1, and a cylinder s, Fig. 5, all concentric with the filament f, or by sets of parallel wires c2, d2, and a cylinder s1, Fig. 6. Reference has been directed by the Comptroller to Specifications 23024/12 and 252/14.
