Abstract: 436,922. Valve modulating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Oct. 25, 1934, No. 30675. Convention date, Oct. 25, 1933. [Class 40 (v)] The output from a carrier - wave amplifier R is modulated by signal voltage applied through a transformer M both to the anode and to the screening grid, the circuit being so arranged that the variations in screen-grid voltage are not in linear relation with the anode voltage variations, but are designed to give linear modulation of the output of the valve R. As shown, a portion of the tapping on the transformer secondary is connected in suitable phase to the grid circuit of an auxiliary valve V, the plate circuit of which includes a resistance which lies in the screen-grid circuit of the main valve R. The Specification as open to inspection under Sect. 91 comprises other circuit arrangements in which the transformer secondary is connected across the anode and cathode and the screengrid is connected directly to a tapping on a potentiometer across the secondary. The H.T. source may be placed between the cathode and the potentiometer, and a further source with its negative end towards the screen-grid may be placed in the screen-grid lead. The tapping may be on the transformer secondary coil itself ; or the transformer may have separate secondaries for the plate modulation and screen-grid modulation respectively. This subject-matter does not appear in the Specification as accepted.

Abstract: 283,921. Kamensky, B. Jan. 20, 1927, [Convention date]. Casings; insulation. - A submersible electric motor has all free spaces in the casing filled with a solid insulating mass in order to decrease to the lowest possible degree the free, air content, of the machine. An air or gas cushion may be inserted between the pressure of the outer medium and the inner surfaces of the casing. As shown in Fig. 1, the insulating filling V is placed in the casing at the ends of the stator S so as to enclose the terminal attachment St. Entry of the external medium is prevented by an inverted bell Bu at the upper end of the shaft, rotation of which causes the enclosed liquid to assume the curved form shown and give a gas seal. Fig. 2 shows a form in which separate filling V<1> is used for the upper terminal chamber and in which the sealing bell is at the lower end of the shaft. 'I'he sealing chamber mav be single or multiple-walled, as shown respectively on the right and left-hand sides of the drawing. The Specification as open to inspection under Sect. 91 (3) (a) includes the application to " submerged high-pressure engines " in general and the use of an insulating filling mass not necessarily solid.

Title: Rotary web undersurface printing machines
IPC: B41F13/04
Filed: 1933-11-13
Abstract: 428,611. Rotary intaglio-printing machines. BARKER, R. W., 56, Ludgate Hill, London.-(American Bank Note Co. ; 70, Broad Street, Manhattan, New York, U.S.A.) Nov. 13, 1933, No. 31568. [Classes 100 (i) and 100 (ii)] In a rotary web undersurface printing - machine having an impression cylinder 11 with a flat portion between the ends of the blankets and a plate cylinder 10 adapted to receive a plurality of printing-plates 12, 13, 14 arranged in spaced relation, the web 43 is fed during the periods of impression by friction between the cylinder 11 and the plates and is held substantially stationary during the periods between the printing operations. In order to ensure that there is no gap between the impressions on the web, the web is withdrawn to a slight extent after the printing in order to correct any over-feed by the printing elements. This is effected by means of clamping members 33, 34, Fig. 7, mounted in a reciprocating carriage 29, Figs. 1 and 5, which is operated by a rack 18 and spur gearing driven by a gear sector 24 on an oscillating lever 25 operated by cam segments 75 which are adjustable circumferentially on the cylinder 10, so as to vary the length of the cam in accordance with the length of the design. The extent of movement of the carriage 29 can be limited by means of an adjustable screw 28 which engages a fixed stop to limit the inward movement of the carriage. The clamps 32 are opened and closed by adjustable cams 71 secured to the cylinder 10, which oscillate a lever 51 connected by a link 50 to a shoe 42, Fig. 4, supported by parallel links 44, 45 and adapted to act on a lever arm 40 which opens the clamp against the action of a spring 35. The clamp is preferably open as it moves to the cylinders and is closed to grip the web as it moves away therefrom. To maintain a constant drag on the web it is passed over a metal plate 64 against which the web is pressed by means of a roller 55 having a friction surface and mounted in bearing blocks 56 aeted on by adjustable screws 62 secured to cap plates 57 pressed towards the plate 64 by adjustable springs 60, 61. The plate 64 may be lowered by means of an eccentric when threading the web. A guide roller 67 carried by adjustable rock arms directs the web as it approaches the printing members. When the throw-off mechanism of the press is operated to cause the printing-couple to rotate without making impressions, the clamp ing members 33, 34 are maintained in contact with the web, and the carriage 29 is prevented from reciprocating. The link 93, Fig. 1 of the throw-off mechanism of the press is connected by lever and link mechanism to a hook 95 which engages a stud 94 on the lever 25 when the press is thrown off, and by means of a link 89, one slotted member 85 of the shoe 42, which is formed of two similar members 84, 85, is moved relatively to the other member 84 to bring recesses 88 into register with the roller 41 of the pivoted clamp, and the clamp is thus not moved to open position when the shoe is raised.
