    Abstract: There is disclosed a multiple gaseous discharge display/memory panel having an electrical memory and capable of producing a visual display, the panel being characterized by an ionizable gaseous medium in a gas chamber formed by a pair of opposed dielectric material charge storage members which are respectively backed by an array of electrode (conductor) members such that each array of electrode members is insulated from the gaseous medium by a dielectric member, the electrode members behind each dielectric material member being oriented with respect to the electrode members behind the opposing dielectric material member so as to define a plurality of discrete discharge volumes, each discharge volume constituting a discharge unit, the dielectric material being selectively enriched with at least one Group IA or IIA element in an amount sufficient to provide operating voltages which are substantially uniform and which do not significantly change with time.

    Abstract: A low voltage incandescent lamp constructed from a reflector and a cover glass both consisting of pressed glass and which is referred to as a sealed beam type. Through the rear wall extend two conductors between which a filament is stretched. The filament, which may be subjected to impact is fixed by means of a bridge which comprises an electrically insulating mass through which extend two supporting wires. The supporting wires at their free ends are connected to the conductors at spaced points.The innovation relates to an electric incandescent lamp, in particular a low voltage lamp, which comprises a hermetically sealed envelope which is constructed from parts of pressed glass and in which at least one filament is stretched between a set of current conductors secured in the wall of the envelope, in which between the filament and the connection site of the conductors a bridge is provided in the envelope and is formed as a member of electrically readily insulating material from which at least two supporting wires emanate on both sides which are secured to the conductors in places shifted in the longitudinal direction of the conductors. Such an incandescent lamp is known from U.S. Pat. No. 2,497,567.The bridge used in the known lamp can be composed only manually. This is to be ascribed mainly to the shape of the bridge which is formed as a beam of rod glass. In each of the end faces thereof, a few supporting wires are secured by means of a suitable thermal treatment. The beam is softened at its ends and supporting wires of a previously determined length are secured in said ends. As a result of this a beam is obtained which shows two projecting supporting wires at each end. The projecting wires are then secured to the conductors by means of a suitable spot-welding method.It is an object of the invention to provide a bridge construction which on the one hand can be manufactured by means of a conventional machine for the manufacture of lamp mounts and on the other hand requires less glass material while maintaining the usually required mechanical rigidity.For that purpose the incandescent lamp according to the innovation is characterized in that the two supporting wires emanating from the member and secured to the same conductor constitute the two free ends of a supporting wire led through the member. In a bridge construction chosen in this manner the possibility is presented to secure each set of free supporting wire ends in places of the conductor farther remote from each other as is the case in the conventional bridge, while maintaining the mechanical rigidity of the assembly. The bridge is preferably formed as a glass bead having incorporated therein parallel extending supporting wires of which the free ends pointing in the same direction are connected to the conductors in a position in which they are bent apart.

    Abstract: A unitary heater, cathode, and control electrode structure for an electron discharge device is formed by coating a disk of a porous refractory metal with an inorganic insulating layer, overcoating the insulating layer with a film of refractory metal, forming a grid pattern in the film on one side of the disk, forming openings in the film and insulating layer corresponding to the pattern, and impregnating the disk with thermionic emissive material.
