Abstract:
There is disclosed an apparatus for welding leads to the electrodes of an ultrahigh voltage mercury vapor lamp. The apparatus comprises a base having guide rails, a clamp mounted on the guide rails, a working part for welding the leads to the electrodes and then cutting the leads, and a lead supplying mechanism for introducing the leads into the working part.
Abstract:
A method of manufacturing a cathode ray tube, in which the positions of the tube envelope and the gun assembly are adjusted so their respectively longitudinal axes coincide, and then fixed against non-axial movement prior to insertion and sealing of the gun assembly into the neck of the envelope, wherein the gun assembly position is fixed by clamping at least three of its connector pins.
Abstract:
The apparatus comprises an endless tunnel having a wall provided with openings giving access to processing chambers in a locked chamber which has a panel sealing the apparatus from the external environment. A conveyor which follows a closed path is arranged in the tunnel and is provided with seats for containers with articles to be processed and transport means for introducing articles carried by the conveyor into positions opposite to a chamber into a respective chamber. The apparatus has structure by which the environments in the tunnel and in each of the chambers can be controlled. The chambers can each be sealed from the tunnel in a vacuum-tight manner. By means of this apparatus articles, which are screened from the surroundings in a vacuum-tight manner, can be subjected in a controlled environment to a variety of processing steps.
Abstract:
A method and apparatus for manufacturing a lamp involves preparing a lamp assembly having a base to which is coupled a bulb with external lead-in wires. One of the lead-in wires has an outer end which is drawn out between the bulb and the edge of the base. A potential is applied between a welding electrode of a welding device and the tip of the outer end of the external lead-in wire to weld the lead-in wire to the base. During this applying of potential, a gas flame is interposed between the outer end of the external lead-in wire and the welding electrode.
Abstract:
The method includes locating three frame-positioning points on a faceplate panel and measuring the panel contour at at least four spaced points on a circle of given radius at a first spacing with respect to the frame-positioning points. Then, at a remote location, (a) a frame assembly is oriented on three reconstructed frame-positioning points which are in substantially the same geometric relationship with respect to one another as are the frame-positioning points on the faceplate panel, (b) signals are generated related to the position of the measured contour of the panel, and (c) the signals are utilized to position four mask supports in substantially the same geometric relationship with respect to one another as are the measured contour points but at a second spacing with respect to the reconstructed framepositioning points. Then, the contour of the mask is conformed to the contour established by the mask supports. With the mask conformed to the contour of the mask supports, the mask is permanently attached to the frame. A particular embodiment of the method also includes measuring the contour of the faceplate panel substantially at the center of the panel, measuring the contour of the mask substantially at the center of the mask and adjusting the second spacing to obtain a desired center spacing between the mask and panel when the mask is mounted in the panel while maintaining the mask conformed to the contour established by the mask supports.
Abstract:
The elongated filament of a lumiline- or showcase-type incandescent lamp is initially wound as a coiled coil filament and attached to the lead wires of the mount assembly. When a getter is used, the getter is applied to the primary turns of the coiled coil filament before it is stretched and remains on the primary turns of the resulting singly coiled filament that is attached to the mount assembly.
Abstract:
Methods are disclosed for making cylindrical cup electrodes for three-gun color picture tubes having internally mounted shield inserts of magnetic material affixed to the inner walls of the cup. The upper rim of the cup is kept intact and may be flanged outwards to improve roundness after apertures are formed in the cup sidewalls. Apertures in the cup walls are confined to those required for magnetic pole pieces extending into said cup comprising three pairs of slits in the sidewalls of the cup.
Abstract:
The present invention relates to a radiation generating tube. The radiation generating tube includes an envelope including an insulating tubular member having at least two openings, a cathode connected to one of the openings of the insulating tubular member, and an anode connected to the other of the openings of the insulating tubular member. At least one of the cathode and the anode and the insulating tubular member are bonded at a bonded portion with an electrically conductive bonding member; and the bonded portion bonded with the electrically conductive bonding member is coated with a dielectric layer.
