Title: Improvements in radio receivers employing four electrode valves
IPC: H03F1/13
Filed: 1927-05-07
Abstract: 271,850. Soc. dite la Radio-Industrie, and Compagnie pour la Fabrication des Compteurs et MatÚriel d'Usines Ó Gaz. May 29, 1926, [Convention date]. Addition to 266,325. Void [Published under Sect. 91 of the Acts]. Thermionic amplifiers and detector.-The fourelectrode valve circuit for wireless reception described in the parent Specification is modified by connecting the return leads of the grids 'and plate to the negative terminal of the filament supply source S, and by inserting the filament rheostat R between that negative terminal and the filament. Adjustment of the rheostat thus varies the filament current simultaneously with a variation of the voltage of the grids and plate, the outer or control grid acquiring a negative bias as the filament current is reduced. The arrangement is stated to facilitate an increase of amplification without causing self-oscillation. The Figure shows a tuned aerial circuit O<1> connected between the outer grid and filament, whilst the positive side of a battery 12 is connected to a centre tap on an output coil AB, the ends of which are connected to the plate and the inner grid respectively. The coil AB is coupled to the tuned grid circuit of a detector valve 2, which feeds a low-frequency amplifier 3. The grid of this amplifier is connected to the common earth lead, and its bias is thus regulated by adjustment of the rheostat R.

Abstract: 674,463. Control of A.C. motors. KIEBACK, E., and PETER, P. May 18, 1950. No. 12417/50. Class 38 (iii). [Also in Group XXXV] Any variable is controlled by a system in which the sensing element operates a switch to determine the numof cycles of a motor driven switch which closes a regulator circuit during a part of each cycle. The switch motor is mounted. vertically so that the rotor drops axially out of the field system onto a braking surface when the motor is de-energized. The system is described with reference to upper and lower sensing limit control of reversible servo-motor, .but may be applied to single limit control of e.g. an electromagnetic valve in a heating system. As shown, sensing element operates a contact 2 co-operating with upper and lower limit contacts 4, 4<SP>1</SP> to control a reversible capacitor feed induction regulator motor 6, through motor driven switches 5, 5<SP>1</SP>. The regulator motor is fitted with limit of travel switches 16, 16<SP>1</SP>. The motor driven switch 5 comprises a stator coil 7 energized over contacts 4 and 23. As the motor starts its driven cam shaft closes a holding contact 11 and opens the contact 23 to relieve the sensing contact of the motor load current. During the revolution of the cam shaft which may take e.g. 12 seconds, a contact 12 is closed for a period of e.g. 2 seconds to energize the regulator motor 6. At the end of the cycle the holding contact 11 opens and contact 23 closes. If the sensing switch 2 has opened the motor stops and the rotor drops onto a braking surface 28.

Abstract: 692,751. Photographic film winding. SIEMENS & HALSKE AKT.-GES. May 30, 1951 [Oct. 1, 1948], No. 12791/51. Class 98 (i). [Also in Group XL (a)] In an electron microscope or similar apparatus, more particularly apparatus of the kind in which a vacuum is maintained therein by means of a continuously operating pump, arrangements for supporting and moving photographic rollfilm are located outside the vacuum chamber, and the part of the film to be exposed lies between two plates acting to seal the chamber and forming an inner gate and an outer gate of a lock for the introduction of the film, the inner gate being closed and the outer gate being open during the feeding of the film, and the outer gate being closed and the inner gate being open and out of the path of the rays when the film is to be exposed. As shown, a wall 5 of the vacuum chamber has a rectangular aperture through which the film is exposed and into which a plate 4 fixed to an inner sealing-plate 3 fits closely. A cranked shaft 7, journalled in the walls of the vacuum chamber, is rotatable from outside by a knob 8, and carries eccentrics 10, 11 which press plate 3 against a rubber seal 2 surrounding the exposure aperture in one position of the knob 8. When knob 8 is turned through 180 degrees, the eccentrics allow the plate 3 to be moved away from the wall 5 by springs (not shown). The cranked part 12 of shaft 7 is shaped to lie out of the path of the rays directed towards the aperture in either position of knob 8. Plate 3 may have a fluorescent screen on its inner face, on which an image is formed when the plate is in closed position. A plate 16 outside the chamber may be moved, against the action of springs 29, towards the wall 5 by means of eccentrics 19, 20 on a rotatable shaft 17. A photographic film, wound between spools (not shown) mounted outside the vacuum chamber, passes between plate 4 and a rubber-covered plate 21, mounted on plate 16 and urged out of parallelism by a spring to expel the air between the plates more readily. If the film is perforated, the perforations lie within the exposure aperture. Plate 21 is then pressed against a rubber seal surrounding the aperture, and then plate 3 is moved out of the ray path by any known means. After the exposure, plate 3 is returned to closed position, and plates 16, 22 are moved away to enable the film to be wound on.
