Abstract: 562,914. Electron beam valves and circuits therefor. COSSOR, Ltd., A. G., JOFEH, L., and WILLIAMS, B. C. FLEMING-. May 7, 1941, No. 6197/42. Divided out of 560,689. [Classes 39 (i) and 40 (v)] In a beam deflection valve used as a mixer, two pairs of deflector plates 1, 2 and 3, 4, Fig. 1, receive the oscillations to be mixed, and a target 11 projects from one side into the electron stream, the target receiving current in dependence on the deflection produced by the first pair of plates. This current may be used to sustain local 'oscillations. The undeflected beam is focused on the edge of one-6-of two output electrodes to which a suitable sum or difference circuit 10 is connected. The circuits 8, 9, 10 may be connected to their associated electrodes in push-pull ; if plates 2 and 4 are both earthed, a single plate may replace the two. In a modification with curved electrodes 13, 14, 15, Fig. 2, such as described in the parent Specification, the beam is brought to two successive focii at the interposed target 11 and at the output 6, 7. A deflection voltage applied over the whole length of the electrodes produces a deflection of the intermediate focus, but not at the final focus. The target electrodes 6, 7 may be replaced by a pair of plates inductively coupled to the beam and forming the output electrodes. According to the Provisional Specification, the beam may be centred automatically by making the D.C. components of the deflector plate potentials dependent upon the D.C. components of the currents collected by the targets ; this may be effected by coupling the input and output circuits of the deflector plates and targets through condenser's while the D.C. connections are taken from'the source-through resistors to the targets and thence through resistors to the deflecting plates on the corresponding sides.

Title: Improvements relating to fish-dressing machines
IPC: A22C25/08
Filed: 1931-02-28
Abstract: 372,455. Dressing fish. ROWTON, J. L., 7, Devanha Gardens, Aberdeen. Feb. 28, 1931, No. 6310. [Class 28 (ii).] The conveyer of a fishdressing machine is provided with means for gripping the tail which are elevated above the general level of the conveyer to receive the fish and then withdrawn below the general level to retract the gripping means from the path of the knives or other tools. As shown in Figs. 1 and 3, the conveyer is of the endless type and the fish is supported upon plate-sets 4, 4a, the sets being spaced from one another to permit discharge of bones, offal, &c. The plates are grooved at 4b to position the fish accurately and the plate 4a is slotted at its edge to permit the rising and falling movements of jaws 6, 7 which are respectively secured to coaxial shafts 11, 10. The jaws 6, 7 have a connecting pin 19, which ensures that they move in unison, and are pressed together by a spring 15 which acts upon the jaw 6. The jaws are moved away from one another to receive the fish by rollers 16 on the shaft 11 engaging with stationary cams 17, 18 on the conveyer framework. The rising and falling movement is effected by arms 22, 23 on the shaft 10 abutting against the stationary ramps 20, 21 also on the conveyor framework. In operation, the jaws are raised and opened to receive the fish and are then closed and swung below the general level of the conveyer. The plates are supported to prevent sagging by strips 5. In a modification, Fig. 7, the gripping jaws do not project above the level of the conveyer plates. The fish is inserted tail first between the gripping-jaws 25 whilst the conveyer plates are rounding the pulley 2, and in consequence the tail is pushed below the level of the conveyer. By the action of cams 26 the jaws close on the tail and maintain it below the level of the conveyer.
