Title: Improvements in thermionic tube amplifying devices
IPC: H03F3/36
Filed: 1920-07-07
Abstract: 173,793. Latour, M. May 11, 1917, [Convention date]. Thermionic amplifiers.-In a system for amplifying slowly varying direct current, the direct current is converted into alternating current by means of a commutator or vibrating interrupter. This alternating current is then amplified by a thermionic amplifier such as that described in Specification 127,318, and then rectified. In the application of the invention to amplifying a current the intensity of which is varied by a lightsensitive element in the circuit, as in phototelegraphy, the interrupter is dispensed with, the light-sensitive element being fed with alternating current which is amplified and then rectified.

Filed: 1947-07-23
Abstract: 657,483. Letting-off warps. GROSVEN- OR-DALE CO., Inc. July 23, 1947, No. 19741. Convention date, July 2, 1946. [Class 142(ii)] In a seersucker loom the crinkle warp beam 3 has a ratchet drive 16 controlled by the tension of the warp and its diameter on the beam. Pawls 18 on a lever 17 are actuated by a cam 20, their idle stroke being limited by a stop 58 carried by a feeler 59, so that the pawls are allowed to increase their stroke as the warp is consumed. The crinkle warp 31 passes round rods 28, 29, 30 on a cam-oscillated frame 33 which varies its tension (ground warp being also supplied by a separate beam). When the tension of the crinkle warp becomes excessive, displacement of the rod 29 against a spring 38 is transmitted by a cable 48 to swing the stop 58 out of the path of the lever 17, thereby allowing the pawls to make a longer stroke.

Abstract: 167,069. Uriga, L., and Landwirtschaftliche Maschinenfabrik Ges. July 9, 1920. Ploughs; adjusting parts of implements; frames for implements; propelling implements.- A manually-operated tilling-implement comprises a tool f such as a plough connected by a bar m to a frame r' on which is pivoted a pedal b which, in combination with a pedal c pivoted on a somewhat larger frame r, is used to propel the implement. The frame r has pivoted on it a handlever a which is connected bv a link d to the frame r<1> and by links s, s' to arms q on the pivots of the pedals b, c respectively. In working, the operator stands on the pedal b thus causing the arm q to move forward and pressing the lever a forward. The operator however pulls the top of the lever towards himself thus forcing its lower end forward with the frame r and an advance cutter k secured thereto. The frame r moving forward relatively to the link s<1> causes the arm q to tilt up the pedal c. After the pedal b has reached the ground, the operator transfers his weight to the pedal c. The movement of the pedal through the arm q and link s' forces the lever a forward, this movement being assisted by the operator bearing forward on the lever. The forward movement of the lever pulls the frame r' with the tool f forward until the pedal c reaches the ground when the operator transfers his weight to the pedal b again. A cross-bar y carrying a gauge is secured to the frame r. A simple modification in which the propulsion is effected by swinging the lever a without using pedals is described.
