Abstract:
A gas discharge panel in which the conductors of the base plate and the upper plate are connected to said base plate and upper plate by means of an enamel.
Abstract:
A television camera tube having an elongate envelope comprising two cylindrical parts. The cylindrical part which is connected to the face plate has a larger diameter than the other cylindrical part and comprises a gauze electrode secured to a supporting ring. This supporting ring is clamped between the face plate and the neck between the two cylindrical parts by means of resilient pressure means. A circular rounding of the neck on the side of the cylindrical part with the smallest diameter is to be preferred, said rounding being covered with a conductive layer. A few dimensions are given related to the diameter of the cylindrical part of the smallest diameter. The ratio between the voltages at the gauze electrode and the conductive layer preferably is between 1.65 and 2.35.
Abstract:
A method of making a gas-discharge panel comprising etching discharge cavities and interconnecting channels between the discharge cavities out of strip-shaped electrodes embedded in insulating plates. The channels are etched beneath the surface of the insulating plate to depths which do not allow a discharge in one cavity to strike a discharge in adjacent cavities.
Abstract:
A prism holder for a digital light deflection system in which the holder is plate-shaped and has an aperture which is larger than the prism, the prism bearing on one side with its corners on a flat ring and being enclosed on the other side by means of fixing members.
Abstract:
A metal article, for example, in the form of a lead-in or sealing conductor or a perforated intermediate plate of a gas discharge panel for picture display preferably consisting of anodised aluminium, in which the thickness of the oxide layer and of the underlying metal core are chosen to be so that the thermal expansion of the article is also determined by the oxide layer.
Abstract:
A measuring cell for determining oxygen concentrations in an exhaust mixture, consisting of a metal housing in which a detachable plate of stabilised ZrO2 is clamped between two metal rings, one ring establishing contact with the housing and the other with a lead-through conductor which is present in an insulating plate provided with gas stream apertures.
Abstract:
A method of manufacturing a perforated plate comprising placing a plurality of tubes in the holes of at least one perforated base plate, and filling the space between the tubes with a material having a lower softening temperature than that of the tubes. This formed block is then cut in a direction transverse to the tubes to form thinner perforated plates.
Abstract:
A metal-to-ceramic leadthrough with the use of glass-like material and an aperture having a narrow portion which changes in a step-wise manner into a widened portion, the gap between the conductor and the wall of the narrow portion being filled entirely with glass-like material and the bottom of the wide portion of the aperture being covered with a thin layer of glasslike material which forms a meniscus against the conductor and the inner wall of the wide portion of the aperture.
Abstract:
1. IN THE METHOD OF MANUFACTURING A GAS-DISCHARGE DISPLAY PANEL COMPRISING AT LEAST ONE BOTTOM PLATE AND ONE TOP PLATE OF INSULATING, TRANSPARENT MATERIAL, THE BOTTOM AND TOP PLATES BEING PROVIDED WITH STRIP-SHAPED RELATIVELY INSULATED CONDUCTORS, PARTS OF THE SURFACES OF WHICH ARE IN CONTACT WITH A GAS ATMOSPHER IN CAVITIES BETWEEN THE CONDUCTORS, THE STEPS OF EMBEDDING A COMBSHAPED CONDUCTOR IN AN INSULATING PLATE WITH THE TINES OF THE COMB-SHAPED CONDUCTOR EXTENDING UP TO THE SURFACE OF THE PLATE, AND THEREAFTER CHEMICALLY ETCHING THE TINES TO FORM CAVITIES IN THE INSULATING PLATE.
Abstract:
A SMOOTH CONDUCTIVE LAYER OF POOT REFLECTIVITY ON AN INSULATING SURFACE IN OBTAINED BY FIRST APPLYING A CHROMINUM NICKEL LAYER WHICH IS OXIDIZED BY HEATING IN IS APPLIED A NICKEL LAYER WHICH IS OXIDIZED BY HEATING IN AIR AT 250* CTO500*C.
