Title: Video-frequency signal-translating system for television receivers
IPC: H04N3/24
Filed: 1941-06-30
Abstract: 545,756. Television. HAZELTINE CORPORATION. June 30, 1941, No. 8225. Convention date, July 23, 1940. [Class 40 (iii)] Retrace lines are extinguished in cathode-ray tube television receivers by means of a circuit which isolates synchronizing pulses, integrates the field pulses and feeds the integrated voltage into the image circuit to vary the signal level corresponding to black applied to the cathode-ray tube. In the form shown in Fig. 1, the detected signal is supplied to the cathode-ray tube 17 through a diode 22 which stabilizes the black-level and a tapping on the diode load resistance 26 is connected to a rectifier 35, which isolates the synchronizing pulses for controlling the synchronizing signal separator 19 connected to the line and field scanning circuits 18. In addition, the field synchronizing pulses are integrated by the resistance 33 and condenser 34 ; and the integrated voltage is fed by condenser 32 to the cathode-ray tube to vary the black-level of the signal to suppress the ray during a substantial part of the field retrace period. In a modification, Fig. 3, the detected signal is supplied from the detector 15 to the cathode-ray tube 17 through two amplifier stages 22, 39, the first one of which has a diode 37 in its grid circuit to stabilize the black-level, and a tapping on its load resistance 26 connected to a diode 43 with a load resistance 44 for isolating the synchronizing pulses, and a resistance 45 in series with a condenser 46 for integrating the field pulses. The voltages on the resistance 44 and on the condenser 46 control electrodes of a repeater tube 47, the output of which controls the synchronizing signal generator 19 for the line and field scanning circuit 18, and also controls through a condenser 51 an electrode of the second amplifier 39 to vary the black level of the signal fed to the cathode-ray tube 17.

Abstract: 892,539. Endless conveyers. POSTMASTER GENERAL. March 9, 1960 [March 10, 1959], No. 8292/59. Class 78 (1). Article carriers, provided with horizontallyextending article-carrying forks and suspended from a chain or like flexible member supported by and guided along a fixed track, are provided with means for rotating the carriers about a vertical axis and through a predetermined angle of less than 360 degrees while travelling from a loading station to an unloading station. As shown, Fig. 1, an article carrier comprising L-shaped members 6 is secured to a sleeve 4 which is rotatably mounted on a rod 3 pivotally mounted on a bracket 2 secured to a guided chain 1. A toothed wheel 7 secured to the sleeve 4 is adapted to engage with a toothed rack 8 positioned adjacent the path of travel of the rod 3 intermediate a loading station and an unloading station, the wheel 7 having twice as many teeth as the rack 8 so that the article carrier is rotated through 180 degrees between the stations and so that the prongs of the carrier extend forwardly on approaching a loading station and extend rearwardly on approaching an unloading station. The sleeve 4 is biased into one of the two 180 degrees positions by means of arms 9, pivoted at 10 to the wheel 7 and urged by means of a spring 11 into engagement with a cam 13, secured to the rod 3 and provided with two parallel cam faces 17. To align the members 6 with corresponding slots provided in articlesupporting platforms at the stations, a member 14 is secured to the sleeve 4 and provided with parallel faces 15 which engage between fixed guides 16 positioned immediately before the stations. In a further embodiment (not shown), the article carriers may have additional sets of horizontally extending forks, in the same horizontal plane or in spaced horizontal planes, mounted in spaced angular relationship one with another, about the supporting member extending downwardly from the chain or similar flexible member. The carrier rotating means is then arranged so to rotate the carrier through an angle corresponding to the angular relationship of the several sets of forks about the vertical axis.

The plate 6 may be of rubber or synthetic resin; or the plate may be of an aluminium-silicon alloy whilst the tubes are of aluminium and in such case the tube ends are aluminium-silica plated and brazing flux is deposited thereon so that brazing is effected when the plates are cast. The casting may be by gravity, or under pressure using the means shown in Figs. 6 and 7. As shown the casting 6 includes a peripheral flange (defining a header compartment), a rim 7 and a fluid connecting piece 12. Half-moulds 14, 15 are brought together (direction f 1 ) and notches therein embrace the tube ends. Then a stem 17 descends (direction f 2 ) and the lower end of the stem is shaped at 18, 19 to penetrate and overturn the tube ends and hold them in position whilst casting is effected. The connection 12 is formed by a cavity 20 in the half-mould 14 and by a displaceable stem 21. The material to be cast or moulded may be injected through each of the half-moulds 14, 15 and through the stem 17; and the half moulds and stem may incorporate heating and/or cooling means.

Abstract: 1,209,795. Centrifugal separators. MINISTER OF TECHNOLOGY. 4 Feb., 1969 [22 Feb., 1968], No. 8618/68. Heading B2P. A centrifugal separator for removing dust particles from air-streams, Figs. 1 and 2, includes at least one flow channel in which a swirl-imparting helical vane assembly 2 extends along the channel from adjacent the inlet right to the outlet thereof with radial clearance from at least part of the peripheral boundary 1 of the channel to define therewith a substantially axially extending passage, and a flow divider 3 located at or near the downstream end of the flow channel to separate air flowing with centrifugally separated dust along the passage from cleaned air flowing through the vane assembly. As shown, the channel boundary is formed by a tube 1 within which the vane assembly comprising circumferentially spaced vanes 5, 6, 7 carried on a core member 4 is supported by circumferentially-spaced longitudinal ribs 8. The helical angle of the vane assembly varies between a minimum at the ends of the assembly and a maximum at approximately half way thereof. The flow divider 3 is bell-mouthed to provide a diffuser section. A number of separators may be assembled side by side to provide a multi-cell unit in which the tubes are hexagonal, Fig. 3 (not shown), the section of tube wall between adjacent tubes being common to both. In a further multi-cell unit, Figs. 4 and 5, a longitudinally extending baffle 11 having radially extending arms mutually spaced at 120‹ is provided in each interstice between adjacent vane assemblies 2. The arms of each baffle bear tangentially against the three respective vane assemblies and the arms of adjacent baffles overlap to provide longitudinal channels between adjacent vane assemblies. At their downstream ends the vane assemblies are fitted in sleeve members 14 surrounding corresponding holes in end plates 12, 13. The end plate 13 is formed with diffuser sections 15. The end plate 12 is pierced with a number of holes (16), Fig. 6 (not shown), disposed between the baffles 11 and the sleeve members 14 so that the channels defined by the overlapping arms of the baffles are connected to the space between the two end plates which surrounds the sleeve members 14. In operation, separated dust and air flow through the channels and are discharged through the holes into the space between the two end plates 'which may be connected to an air filter. The vane assemblies may be arranged to swirl the air in the same or in opposite directions.

The reactants may contain viscosity stabilizers, e.g. acetic acid, metaxylylene diacetate or excess of the dicarboxylic acid or diamine.  Copolyamides may be formed by the inclusion with the reactants of hexamethylene diamine or additional acids.
