Title: Improvements relating to wireless telegraph apparatus operating with relays
IPC: H04B1/10
Filed: 1920-05-25
Abstract: 168,072. Bolitho, J. B. May 25, 1920. Almospherics and undesired signals, eliminating or limiting; thermionic amplifiers and detectors. -Jamming by undesired stations and interference by atmospherics are prevented by employing two or more thermionic receivers each responsive to waves or signals of a certain character, the arrangement being such that all the valves must be active simultaneously in order that signals may be received or recorded. The signals may be transmitted simultaneously on two or more wavelengths, to which separate receiving-aerials are tuned, or a single wave-length with a definite group frequency may be employed, one receiving- set being selective to wave frequency, and another to group frequency, a third receiving-set being employed if desired to eliminate atmospherics. In another arrangement for preventing jamming by signals arriving from a particular direction, one of the receiving-aerials is directive and is set up so as to be unaffected by the jamming signals. Fig. 1 shows an arrangement employing two receiving-sets. The leads 7, 8 and 10, 11 from the selective receiving-apparatus are bridged by resistances 33, 55 and connected across the grids and filaments of two valves C, D. Potentiometers 34, 56 are connected in the grid circuits. The plate circuits include a common resistance 41 across which connections are made to the grid and filament of a valve E. The grid of this valve is given a negative potential by a potentiometer 50 of such value that the potential added by the signals received on either valve C, D separately does not substantially increase the plate current of the valve E and does not operate the recorder 13. When both valves C, D operate simultaneously the rise in grid potential of the valve E is sufficient to operate the recorder.

Abstract: 586,842. Reed plates. MAGNUS, .F. H. Nov. 4, 1943, No. 18334. Convention date, Dec. 3, 1942. [Class 88 (ii)] The reed plate B of a musical instrument, particularly an instrument of the harmonica or accordion type, is moulded of a synthetic resinous material, for example polystyrene, and has a plurality of .reeds 4, 5, moulded integrally with and thinner than the reed plate, each reed being connected only at its heel end 5a to the reed plate and extending substantially along one side plane only of said plate. The reeds thus formed overlie or underlie, as the case may be, an associated slot 3 in the plate B. In the construction shown, the plate is formed integrally with a body section A of a harmonica, the combined unit having a plurality of recesses 2 constituting wind cells. A section C overlies the reed plate and forms a common sound chamber for all the reeds. In a modification, the parts A and B are made separately and are screwed together. The Specification as open to inspection under Sect. 91 describes also a construction in which ,the reed plate is of metal with the reeds, which are of polystyrene, riveted to it. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,269,186. Television. MESSERSCHMITTBOLKOW-BLOHM G.m.b.H. 20 April, 1970 [28 April, 1969], No. 18669/70. Heading H4F. Television-type video information with a frequency of, for example, one image per second, i.e. picture stills, are transmitted over a narrow bandwidth channel using for example a high frequency carrier wave having a modulation width of 30 kHz of which 26 kHz are used for the slow scan video signal and the rest for accompanying sound information. So that the received video signals may be displayed on a conventional television CRT operating at the standard scanning rate, three electrostatic image storage tubes are provided and so arranged that while an image (slow scan) is recorded on one of the tubes, the previously received image that was initially recorded on a second one of the tubes at a slow scan rate is read out and displayed at a fast rate and also rerecorded (restored) in the third tube at the fast rate. This image is alternately read out and rerecorded between the second and third tubes until the received slow scan image is fully recorded in the first tube, whereupon the slow and fast sweep generators of the receiver actuate interconnected switches to enable this recorded image to be read out and rerecorded alternately between the first and the third tubes while the next received slow scan image is recorded in the second tube. The video and audio information may be recorded on a tape recorder at the receiver before being fed to the storage tubes and display.

Abstract: 1,106,620. Slip and friction couplings. KALLE A.G. 4 May, 1965 [6 May, 1964], No. 18741/65. Heading F2U. In an adjustable torque-limiting friction coupling, particularly for driving a web-winding roller 9, driving inner and driven outer rings 1, 2 define a chamber 12 housing the torque-limiting coupling friction means and have radially opposed circumferential V-section grooves within which are arranged balls to form a ball bearing 7 providing radial and axial support for the outer ring on the inner ring, the inner ring 1 having a relatively axially adjustable part 6 for taking up bearing play, and the inner and outer rings having overlapping portions 1a, 2a defining a seal between the chamber 12 and the bearing 7. The winding roller 9 is releasably frictionally coupled to the outer ring 2 by a garter spring 4 in a groove 4a formed on one side by the outer ring and on the other side by a threaded ring 3 rotatable on the outer ring between two stops. Predominantly perpendicular side walls of the groove are interrupted by inclined sections projecting into the groove towards the spring. By rotating the ring 3 from a spring retraction position in which the inclined sections of the ring 3 are opposite the perpendicular sections of the ring 2 to a position in which the inclined sections of both rings are opposite one another the spring is outwardly pressed to frictionally engage the winding core. Projections 16 on the outer ring serve as stops for the winding roller which has a corresponding number of internal recesses so dimensioned that when in register with the projections they permit axial withdrawal of the roller. The torque limiting coupling friction means comprises shoes 8, 8<SP>1</SP> anchored on the inner ring 1 and expanded into engagement with the outer ring 2 by a spring 14 (which may be rubber) interposing the shoes. The force of the spring is adjusted to vary coupling torque transmission by relative circumferential movement of the shoes. The shoe 8<SP>1</SP> is pivoted, at 13<SP>1</SP>, directly on the inner ring, whereas the shoe 8 is pivoted, at 13, on an adjusting ring 10 clamped to, and circumferentially adjustable with respect to, the inner ring. The adjusting ring 10 is clamped by screws 11 which together with adjusting ring slots 17 determine the adjustment limits. The shoes may be of brake lining material.
