Title: An improved method for the measurement of alternating voltages
IPC: G01R19/22
Filed: 1925-12-18
Abstract: 259,071. General Electric Co., Ltd., and Farnsworth, J. Dec. 18, 1925. Vacuum or low-pressure apparatus, arrangements of.-Small alternating voltages are measured by means of triodes V<1>, V<2>, the voltage being rectified by the first triode V<1> in which the grid bias and anode voltage are so related that the mean anode current is nearly zero in the absence of alternating voltage, the output circuit of this triode being connected to the input circuit of the second triode V<2> so that the current in a direct-current measuring instrument G in the output circuit decreases when the mean anode current of the first triode V<1> increases. A single battery B of 24 volts supplies the filament current and also the grid and anode potentials for both triodes V<1>, V<2>. In series with the battery B are resistances R<1> - - R<4>, the valve filaments F<1>, F<2>. and optionally an ammeter M. Across the input terminals X, Y is connected an impedance Z of high value through blocking condensers C<1>. The anode of the triode V<1> is connected to the junction of the resistance R<2> and filament F<2> through a resistance R<5>, and is also connected to the grid of the triode V<2>. The anode of the triode V<2> is connected through a galvanometer or similar instrument G to an adjustable point on the resistance R<3>. The priming potential for the grid of the triode V<1> is provided by the voltage drop in the resistance R<1> and is so chosen that the current through the resistance R<5> is reduced towards zero when there is no applied alternating electromotive force across the terminals X, Y. A condenser C<2> may be added to obtain a smoother unidirectional electromotive force.

Filed: 1955-11-10
Abstract: 780,559. Control systems for heaters. COLLIER, R. Nov. 10, 1955, No. 32199/55. Class 38 (4). The temperature of heater 5, such as a hotplate energized from a source 6, is controlled by an adjustable thermal cycling switch 14 which causes periodic energization of an electromagnetic switch 7 having contacts 8 in the heater circuit and having its operating coil 9 supplied from a low-voltage source 11 and rectifier 10 over the contacts of the cycling switch, there being a further switch 12, 15, responsive to the temperature of the vessel, or the like, being heated, having contacts in series with the cycling switch and coil 9 so as to de-energize the contactor upon the vessel reaching a predetermined temperature and prevent further heating until the temperature of the vessel falls below the predetermined value. As shown, any one of four temperature-responsive switches 12, set to operate at different temperatures and having a common contact 15, may be selected by a two-gang switch 13 having contacts so interconnected that when one of the higher temperature settings is selected, say switch position LF, the temperature-responsive switches having lower settings, say those operative when switch 13 is set to positions B, S or W, short-circuit the cycling switch 14, so that the heater quickly heats up to the maximum temperature obtainable from position B of switch 13, whereupon the cycling switch becomes effective to regulate temperature over the range extending up to the response temperature of the switch 12 selected at position LF of switch 13. A pilot lamp 23 may be provided. The contactor 7 may be replaced by a solenoidcontrolled gas valve in the case of a gas-heated hot-plate. Specification 760,296 is referred to.

Title: Improvements in and relating to cathode ray tubes
IPC: H01J29/46
Filed: 1948-12-15
Abstract: 672,779. Cathode-ray tubes. ELECTRONIC TUBES, Ltd., and WOODBRIDGE, L. A. Feb. 15, 1950 [Dec. 15, 1948], No. 32495/48. Class 39 (i). In a cathode-ray tube having two pairs of deflecting plates for deflecting the beam in two mutually perpendicular directions, each plate 10, 11, Fig. 1, of the pair further from the beam source has an inwardly extending flange 12 forming with the plate a recess constituting a beam trap, and the inner edges of the flanges 12 are convex so that they are closest together at their centres; this is stated to reduce " pin-cushion " distortion. The flanges 12 are at the edges of plates 10, 11 most remote from the beam source and the plates are flared for maximum sensitivity. The flanges are formed by bending the plates. The device is used to record transient or other non-recurrent waveforms and the beam is suppressed just prior to and following the recorded event by deflecting it into one of the beam traps to prevent fluorescence from the screen at these times which would cause fogging of the recording film or plate. A single stroke time base is used, being initiated by a pulse at or slightly before the occurrence, of the event to be recorded. Recurrent time bases may be used. Prior art devices for suppressing the beam in the unwanted periods, or for deflecting it off the screen, or for deflecting it into a beam trap between the deflecting plates and the tube wall, are referred to. The Provisional Specification states in addition that the beam trap may be formed integrally with or fixed to one deflector plate, or may be fixed to both of a pair of deflector plates. The beam trap may be provided on the horizontal and/or vertical deflecting plates. The edges of the plates furthest from the beam source may be curved to reduce pin-cushion distortion, in addition to shaping the flanges.

Abstract: 534,128. Illuminating systems for optical projection apparatus. TECHNICOLOR MOTION PICTURE CORPORATION. Dec. 29, 1939, No. 33031. Convention date, March 4. [Class 97 (i)] An illuminating optical system for a projector comprises a condenser lens unit producing an image of the light source at a distance from the condenser at least five times that of source, together with a field lens unit between this image and the object, the arrangement being such that the source is imaged by both units acting togetber in the projection lens, and the surface of the condenser lens facing the source is imaged beyond the object. The system shown comprises a condenser unit formed by lenses L', L<SP>2</SP>, the latter being of meniscus form and preferably having a parabolic rear surface D<SP>4</SP>, together with a field lens B situated at a distance from the condenser unit equal to about six to eight times the axial focal length of the latter and having a parabolic front face D<SP>5</SP>. The condenser unit forms an image of the light source S at I<SP>1</SP>, the field lens forming a second image at I<SP>2</SP> in the pupil of the projection system E. The image of the front face D<SP>1</SP> of the condenser unit is formed in a plane I<SP>4</SP> in front of the projection aperture, so that dirt on this face of the condenser does not disturb the projected image. A mask 2 may be placed in a plane P about half way between the light source and the face D1 of the condenser, and an image of it will be formed at the projection aperture O, the mask serving to shield the film in the neighbourhood of the aperture from heat. A mask, such as a metal gauze 3, may be placed at I<SP>1</SP> to reduce the illumination intensity, or between I<SP>1</SP> and D<SP>4</SP> for vignetting purposes, for example to reduce the light intensity at the centre of the screen. In a modification, the field lens comprises two plano-convex lenses separated by a space through which cooling water is circulated. Suitable dimensions for the system are given in the Specification.
