Title: Improvements in high frequency telephone systems
IPC: H04M7/16
Filed: 1923-12-20
Abstract: 230,928. Turner, S. Dec. 20, 1923. Arrangements for supervising interstation signalling; relaying systems.-In a high frequency duplex telephone installation, wireless or wired wireless transmitting and receiving stations T, R are arranged so that the transmitter T is set in action by a starting relay SR under the control of a control relay C, and the latter is controlled by a slow release relay D energized on receipt of oscillations from the, distant station. Calling is effected' by the insertion of plug 1 of an ordinary low frequency telephone circuit into a jack 2, energizing relay C, O which completes the circuit of the starting relay SR and prepares the circuit of the relay D. At the distant exchange the incoming oscillations cause relay B to be actuated and light calling lamp CL, and oscillations are sent out on the plug 1 being inserted in the jack 2; but the lamp C to the calling station is not lighted due to the preparation of the relay D. The removal at either station of the plug 1 closes down the transmitter, thus breaking the circuit of relay D at the other station. and the armature, momentarily held, causes relay C to operate. Relay C gives a clearing signal c, l, breaks the circuit of the starting relay SR and locks itself; it returns to normal only when the plug 1 is removed.

Abstract: 480,203. Distributers for seeds and manures. RODDA, B. N. Nov. 24, 1936, No. 32148. [Class 6 (i)] An auxiliary distributer for receiving grain or fertilizer, or both, from a main distributer and discharging it at a uniform rate comprises a roller and a coacting member forming between them a V-shaped channel into which the material is fed and from one end of which it is discharged, the spreading of the material in the channel being achieved by having the wall of the channel formed by the roller continuously moving upward and the wall formed by the coacting member either stationary or also continuously moving upward, and the movement of the material along the channel being achieved by having the channel inclined or the roller spirally grooved, or both. The feed wheel 5 of the main distributer delivers the grain &c. into cups 7 from which it falls into the V-shaped channel formed between two rollers 9, 10 driven by bevel and spur gearing. The rollers are inclined so as to deliver the grain into a bottomless cup 21 at the top of a tube leading downwards to a share or disc. Inclined guide plates 31, 32 may be located in the cups 7. The rollers 9, 10 may be made of hard wood, composition, or metal, or of rubber or other resilient material, and their surfaces may be partly or wholly grooved spirally. They may be spaced apart or in contact, and their bearings may be removably fixed or may be movable under spring action. A casing may be provided around the rollers, and brushes to keep them clean. In a modification one of the rollers is replaced by a spring-loaded or other inclined plate having a curved surface or shoulder adjacent the other roller.

Title: Improvements in wireless telegraph receivers
IPC: H04B1/12
Filed: 1921-12-01
Abstract: 189,645. Turner, L. B. Dec. 1, 1921. Atmospherics, limiting; thermionic amplifiers. -Relates to thermionic limiting-devices interposed between the aerial and the detecting circuits, of the kind in which the plate potential is set at a low value in order to minimize disturbances arising from atmospherics. The invention consists in the provision of balancing-means of the kind described in Specification 119,365, for neutralizing the effect of electrostatic coupling between the grid and plate of the valve, the arrangement presenting a symmetry which is stated to render it equally effective with transient impulses as with steady alternating electromotive forces. As shown in Fig. 1, the grid potential is controlled from a potentiometer C, whilst a potentiometer G and battery F serve to determine the mean potential of the junction point of two equal impedances D, E in the output circuit. A variable condenser H serves as the balancing-device, one plate being joined to the grid, whilst the other plate is connected to the impedance E. The output terminals P, Q may be connected to the grids of two equal amplifying-triodes with opposed plate circuits. An alternative arrangement is shown in Fig. 3 wherein a split inductance K is coupled to a coil M across the output terminals Y, Z. Preferably the aerial and other circuits preceding the limiting-device should be heavily damped, the necessary selection being secured by the use of highly-resonant circuits in the succeeding stages. A high-frequency aperiodic amplifier may be inserted between the aerial and the limiter in order to adjust the amplitude of the impulses applied to the grid of the limiter to their optimum value.
