Abstract: A remote compression-type latching mechanism is provided which comprises an actuator assembly, an elongate rod connected to the actuator assembly for lateral movement in response to actuation of the actuator assembly, a bracket, and a pawl disposed within the bracket and connected to a remote end of the rod for sliding and pivoting movement in response to movement of the rod. The movement of the pawl is guided and facilitated by slots within the bracket, which also provide positive over-center latching in a preferred embodiment. Upon pivoting to the latched position, the pawl contacts a frame to draw the closure member up against the frame under compression.

Abstract: An inline electron gun for a cathode-ray tube has three cathode assemblies each including a cathode sleeve having a cathode cap closing one end of the sleeve and extending therealong. Each cap has an electron emissive coating thereon and a heater is disposed within each sleeve. The center cathode assembly has a laminated bimetal cathode cap comprising a first layer integral with the sleeve and an overlying second layer with a sidewall portion that is shorter than the sidewall portions of the two outer cathode caps of the outer cathode assemblies. The center cap thus has less thermal mass than the outer caps and the center cathode assembly therefore reaches electron emission temperature before the outer cathode assemblies.

Abstract: In a cathode-ray tube an inline electron gun assembly includes a center cathode assembly disposed between two outer cathode assemblies. The center cathode assembly and the outer cathode assemblies each comprise a tubular cathode sleeve having oppositely disposed ends, a filament disposed within the sleeve and spaced therefrom, and a cathode eyelet coaxially surrounding at least a portion of the cathode sleeve. The cathode sleeve is open at one end and closed at the other end by a cap having an electron emissive material thereon. The open end of the cathode sleeve is attached to the interior surface of the eyelet. At least a portion of the interior surface of at least one of the eyelets is modified to change the radiant energy emission characteristics thereof.

Abstract: An in-line electron gun assembly for a color television picture tube has a control grid and a center cathode disposed between two outer cathodes. The control grid and the cathodes are secured to a pair of insulating support rods. Each cathode is supported by a cathode support assembly comprising a cathode eyelet and a beading support member. Each beading support member varies in dimensions as a function of temperature and the center beading support member stabilizes at a higher operating temperature than the outer beading support members. The ends of the beading support members are embedded in a pair of oppositely-disposed insulating support rods. The center beading support member is formed of a material having a high thermal expansion coefficient and the outer beading support members are formed of a material having a lower thermal expansion coefficient.
