Filed: 1931-05-11
Abstract: 374,231. Tipping-apparatus ; shoots. ROGERS, F. H., 181, Queen Victoria Street, London.-(Pohlig Akt.-Ges., J. ; 115, Weyerstrasse Weg, Zollstock, Cologne, Germany.) May 11, 1931, No. 13918. [Classes 78 (i) and 78 (iv).] In a wagon tipping apparatus for conveying loose material, such as coal, across the buffer space of a railway wagon to another means of conveyance, for example a shoot, a shoot 7, pivoted on a pin 9 supported in a slot 10 at each side of a frame 3 on a tipping platform 1, is adapted to be tilted against the end of the wagon to cover the buffer space. The shoot is normally held in the position shown in Fig. 1 by stops 14 on the frame 3 engaging side arms 12 and by a pawl 15, rotatable about a vertical axis, engaging one of the arms. When a wagon has been run on the platform 1 against a beam 4 on the frame 3, the pawl 15 is rotated by hand whereupon the pin 9 slides along the slots 10 and the shoot 7 falls into the position shown in Fig. 2. The shoot is then locked in this position by rotating a lever 16 which, by a spring 17, presses a lever 18 against the pin 9. The platform is now tilted until the wagon is discharged when the lever 16 is returned to its initial position and the pin slides back along the slots 10. The shoot is then tilted into its horizontal position, Fig. 1, by the arms 12 and is locked by the pawl 15 which rotates due to its own weight and engages one of the arms 12. The platform 1 is then returned to its untipped position.

Abstract: 440,612. Valve amplifying circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. May 18, 1935, No. 14606. Convention date, May 29, 1934. [Class 40 (v)] To prevent distortion in a push-pull Class B amplifier due to variation of anode supply voltage, the grid bias is varied in dependence on the anode voltage. The biassing resistance 6 of the push-pull pair 1, 2, is connected to a circuit comprising a voltage source U1 and a valve 9, so that the P.D. across 6 is dependent on the anode current of valve 9. A tapping is taken from a resistance 8 in the common anode circuit of the valves 1, 2, to a tapping on a further resistance 11 across a voltage source U2, the negative side of which connects to the grid of valve 9. Increase in anode voltage applied to valves 1, 2, from Ua decreases the grid bias of valve 9 ; the resulting increase in anode current of this valve increases the drop across resistance 6 and therefore the grid bias of valves 1, 2. The anode-cathode circuit of 9 is preferably shunted by a resistance 10.
