IPC: H04N5/66
Filed: 1932-03-05
Abstract: 380,522. Television apparatus. MOBSBY, E. G. H., 5, Talbot Houses, Blackheath, London. March 5, 1932, No. 13480. [Class 40 (iii).] Apparatus for varying the intensity of a radiation from a constant source in accordance with variations of an electric current, applicable for recording sound and in television, comprises an achromatic convex lens with axially spherical surfaces, a source of radiation placed at twice the focal distance at one side of the lens to produce an image at the same distance on the other side, and a shutter fixed to a moving coil vibrated electromatically by the varying current positioned at, and movable in the line of, the image. Alternatively, the lens may be replaced by a truly spherical concave mirror in which case the source and image are adjacent to each other at the centre of curvation of the mirror. The image should not subtend an angle of more than two degrees on each side of the optical axis. In a television reproducer, the varying intensity passing the shutter S, Fig. 3, is concentrated by a condenser B upon a system of square holes in a scanning disc D arranged in front of a projection lens P.

Abstract: 630,843. Radio navigation. O'BRIEN, W. J. Aug. 26, 1946, No. 13585/49. Convention date, Aug. 27, 1945. Divided out of 630,435. [Class 40 (vii)] A receiving apparatus for use with a radio-navigational system wherein radio frequency signals of unlike but harmonically-related frequencies having a fixed multiple phase relationship are transmitted from spaced points comprises two adjustable receivers tunable to said signals, a pair of amplifiers tunable to two other frequencies of value equal to the ratio of the incoming signals and fed from the same source of adjustable frequency oscillations, and means for combining the outputs of each receiver and corresponding amplifier to produce a pair of beat signals of fixed frequency whose multiple phase relationship is determined. Such a receiver is of particular use when a number of positiondetermining systems such as that described in Specification 620,479, utilizing different frequencies, are operated to cover a large area. A receiver for such a wide coverage system comprises variable frequency receivers 31, 32, and 33, fed through switches 34, 35, 36 from antenna 37, and coupled to mixer and detector stages 41, 42, 4,3. In the example shown the frequencies received are 80, 60 and 90 kc. respectively. Variable frequency amplifiers 44, 45 and 46, preferably of regenerative type, tuned in the present example to frequencies of 93<1>/3, 70, and 105 kc. are connected respectively to the mixer stages and are fed by a variable frequency harmonic generator 47 through a high pass filter. Fixed frequency amplifiers 59, 60 and 61 amplify the beat frequencies of 13<1>/3, 10 and 15 kc. which are multiplied up as shown for phase comparison in pairs at 40 kc. and 30 kc. The phase difference indications given by meters 70 and 77 are the differences at reference frequencies which are the lowest common multiple of signals of each pair. The receiver may be used with another transmitting system radiating signals of different frequencies which are similarly harmonically related by varying the tuning of units 31, 32, 33, 44, 45, 46, and 47 and preferably the tuning controls of these units are ganged to provide a single control. The variation of the local signals is such that the same beat frequencies are produced. To check the operation of the system switches 34, 35 and 36 may be thrown to connect a harmonic generator reference oscillator 79 to the receivers when a known check reading, preferably adjusted to zero during construction, should be shown by the indicators. Specifications 584,727; 620,480, [Group XXXVI], 620,481, 620,507, [Group XXXVI], and 625,983 also are referred to.

Title: Improvements in devices for transmitting a sequence of telegraphic or like impulses particularly for testing purposes
Inventor: PYATT EDWARD CHARLES
IPC: H04L12/26
Filed: 1946-05-07
Abstract: 637,716. Pulse generating and distorting circuits ; relay circuits. TELEPHONE MANUFACTURING CO., Ltd. May 7, 1946, No. 13785. [Class 40 (vi)] [Also in Group XL (b)] In a system for generating accurately timed pulses, approximately timed pulses of variable spacing and duration and accurately timed signals of constant spacing and duration are fed to a device which operates to produce the desired pulses. An oscillator A feeds sine waves of sufficient amplitude to the cathode coupled trigger pair V1, V2 to cause the pair to reverse their state, thus generating square waves across resistor R6 which are differentiated by capacitor C1 and resistor R8. Valve V3 is biassed beyond cut-off, only the positive pulses being effective to produce positive and negative trains at the cathode and anode respectively which are fed to valves V5, V4. The oscillator A also feeds, through an amplifier, a synchronous motor driving a slotted disc P.D., a light source L.S. intermittently illuminating a photo-cell P.C. Variations in potential across the photo-cell are fed through cathode follower to operate the trigger pair V10, V11, the output pulses being applied to gate the valves V4, V5. The valves V4, V5 are normally biassed to saturation and cut-off respectively, the gating signals rendering one or other operative to feed a series of positive or negative pulses to the amplifier valve V6. The first of the series causes the trigger pair V7, V8 to reverse, operating relay RA and generating the leading edge of a rectangular waveform across resistors R31, R32. Upon cessation of the gating signal, the first pulse of the other series is effective to restore the trigger pair, thus terminating the rectangular waveform. The rotating disc may be of non- magnetic material carrying magnetic studs co-operating with fixed windings or an insulating disc with conducting studs co-operating with a fixed brush. As a further alternative, a cathode-ray tube may be used with a mask having suitable apertures. Distorting pulses. The pulses appearing across resistors R31, R32 are integrated over resistor R41 and capacitor C3 and fed through valve V12 to operate the trigger pair V 13, V14 and relay RB. By varying the setting of potentiometer R45 the degree of distortion may be varied, Fig. 5 (not shown). Reference has been directed by the Comptroller to Specification 607,443.

Abstract: 1494472 Continuous casting FIVES-CAIL BABCOCK 4 April 1975 [5 April 1974 14 May 1974] 13981/75 Heading B3F [Also in Division B8] For removing single or pairs of rollers 8 from a roller guideway for the cast strand of a continuous casting installation, a carriage 10 is displaced along a path parallel to the guideway (and provided by rails 9 in which rollers 12 of the carriage can run); a pair of straps 22 for connection to the rollers 8 are suspended from a pair of carriers 23 each conveyed by a chain 16 of a lifting mechanism and mounted on rollers 24 for displacement along a slide 25 which in turn is displaceable on its rollers 26 along a track 27 to extend to the guideway as shown; to angle the slides 25 according to the disposition of a part of the curved guideway requiring attention, each of the pair of tracks 27 is swingable, individually by hydraulic jacks 30, on shafts 29 on which they are also slidable for sideways adjustment. The chains 16 are individually driven by way of double pinions 17 by an hydraulic motor 19 supplied from a unit 21 on a frame 11 of the carriage 10, which unit also supplies the jacks 30 and a jack for the sideways adjustment. They can effect a downward thrust on the carriers 23 as well as a lifting force. By means of a spring- loaded latch 33 pivoted on each bracket 23 and which can cam on a lateral projection at the top of the corresponding slide 25, the slides are connected to the carriers and thus to the chains 16 for their extension movement to the guideway when required. The ascending carriers 23 with their roller load rise up to the top of the slides 25, when the latch 33, by cam action, lifts pawls 35 from racks 38 on the roller tracks 27 and latches again on the slides 25 to retract them as they continue upwards. The carriage 10 is driven by way of pinions 13 and racks 14 on the rails 9. In a second embodiment, Figs. 7-11 (not shown) a platform (113) mounted on the carriage 10 carries controls and is supported in such away as to remain horizontal as the carriage moves along the curved rails 9.
