Title: Electronic display tube
IPC: H01J43/24
Filed: 1969-12-11
Abstract: 1298949 Cathode-ray display tubes; electron multipliers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 Dec 1969 [14 Dec 1968] 60554/69 Heading H1D An electronic display tube comprises a planar electron source, first channel plate 7, having its output electrode 8 subdivided in a first array of parallel conductors, second channel plate 9 with output electrode 10 of parallel conductors crossing the first array to define an array of individually addressable points, and a display screen, e.g. luminescent screen. The channels in plate 7 need not be parallel to those in plate 9. The plates may be juxtaposed, the first grid acting as the input electrode of plate 9 in addition to being the output electrode of the first plate. Optional third plate 5 may have output electrode 6 acting as input electrode of the first plate. Post-multiplication plate 13 may be connected to the second grid by additional plate 11. The grid conductors may be separate wires or vapour deposited parallel conductors. Channel-plate 9 voltage should be such that saturation does not occur and reduces the effect of electron passage at undesired points from plate 7. The electron source may be an exposed photocathode but preferably a third plate is provided operating in saturation. The K.E. spread of emitted electrons depends on the collision distance from the exit surface and is reduced by the first plate whose voltage is as low as possible compatible with multiplier operation, and also by relative tilting of the plates. A larger electron flow with selection difficulties may be avoided by multiplication plate preferably united with the preceding plates to avoid cross-talk. When the input electrode of the multiplication plate may be a grid it may be directly united, brightness variations being achieved by grid voltage variations, operation being non-saturated. If the multiplication plate is saturated operated, brightness variations being attained by control of passage times, intervening additional plate 11 is provided. Tube 5 channels may be at 15 degrees, phosphor layer 15 may be on Al layer 16, plates 5 and 13, 1 cm. thick; plates 7, 9 and 11, 1 mm. thick; respective channel diameters in these plates of 200 and 100 Á, the surfaces rendered conductive by reduction to 500 and 20 M # respectively; γ of 3 to 4 at right-angle incidence, conductor 2 of 1 mm. Al; layer 3 of few micron thick Al 2 O 3 ; conductors 4 and 14 of Au for its conductivity with Ni-Cr layers for adherence; conductors 6, 12 of Cr-Ni and Au composite; grids 8, 10 of 0À1 mm. Pt wire, voltages being given (e.g. 100v. across the few Á cathode layer) and with plate 5 channel length to diameter ratio (50/cos 15 degrees) = 52 operates saturated, plate 7 length/ diameter ratio being 10 operates as a multiplier and non-saturated, and similarly plates 9, 11 and 13, the latter having a channel length/ diameter ratio of 50. Characters and numerals may be displayed and TV panel applications are instanced.

Patent GB-2029164-A (GB)
Title: Intercommunication system
IPC: G08B25/01
Filed: 1978-08-23
Abstract: The system is particularly suitable for warden-controlled old people's housing schemes and has a master unit and a plurality of sub- units located one in each flat or house in the scheme. The master unit can selectively transmit to and receive from any sub-unit a speech signal, and each sub-unit has signalling means to transmit a call signal to the master unit to activate an audible or visible alarm e.g. LEDs. The system provides for a reassurance signal e.g. audio tone, to be transmitted by the master unit to the calling sub-unit, to confirm receipt of the call. A privacy switch is also provided in each sub-unit to prevent, when operated, transmission of a speech signal from the sub-unit to the master unit, preventing the master unit being used for 'eavesdropping'. Only a single pair of wires connects each sub-unit to the master unit for these functions. A portable paging and remote control device is associated with an unattended master unit. The sub- units may be controlled by a remote wired switch.

Title: Push-rod for internal combustion engine
IPC: B23K11/20
Filed: 1978-10-03
Abstract: A valve push-rod for an internal combustion engine is formed by electric resistance welding a case-hardened end piece 2 on the end of a steel tube 1 and controlling the rate of cooling following cessation of the welding current. This may be effected by heating the weld zone so as to form in the zone a transition layer 6 comprising a mixed ???- martensite and primary troostite structure 6b, which bridges the annular weld zone boundary around the tube wall in the region of the end of its base. The heating current is applied simultaneously with cessation of the welding current. There is a reduction in the tendancy to generate cracks in the weld zone and the mixed transition layer adds toughness to the welded joint. <IMAGE>
