Abstract: A method of constructing a gas discharge display device in such a manner that contaminants found within the completed display are significantly reduced. The process for assembly of the display incorporates the utilization of a spacer member having a higher melting temperature than the display's perimeter seal and is designed to hold the plates apart without letting certain portions of the sealing material contact the opposing substrate. The use of the spacer member of high temperature material permits a higher temperature to be achieved in the vacuum furnace for evacuating the contaminants produced by out-gassing of impurities in the dielectric and conductive materials as well as the glass substrates and the sealing material. The sealing time for the display after evacuation is shortened to prevent or greatly reduce the possible entrapment of impurities in the display during the higher temperature final sealing step.

Abstract: A component lead wire cutting equipment includes upper and lower levers for gripping a pair of lead wires of an electric component extending in the same direction. A driving device moves the levers. A pair of cutter blades are mounted on the levers to spread the pitch of the lead wires to a given size, and to cut off the lead wires. A pair of regulating convex portions regulate the movement of the lead wires along their spreading direction in the position between the cutter blades and the component body. During the cutting operation of the lead wires the component is prevented from being broken or from being inclined in its body.

Abstract: A collapsible frame for supporting a container is manufactured from two loops formed from a single length of wire which are intertwined to form a handle and sprung to form base members which are yieldably urged apart. An inwardly narrowed neck portion is formed intermediate the handle and the base members to provide points of support for the container. A containment loop encompasses the neck portion of the frame and inwardly urges the points of support against the container as it is pushed into position within the containment loop. The base members are capable of being pressed into a planar assembly when the container is removed to allow a plurality of similarly constructed frames to be compactly stacked.

Abstract: Metal annuli formed of chill cast metal for subsequent conversion into finished products are produced between at least one pair of inner and outer rollers forming between them a roll-pass, the outer one of which is driven and the inner one, of less diameter than the open central area of the annulus being formed and eccentrically positioned in said open central area, is free turning. Provision is made for moving the axis of rotation of the annulus being formd as the overall diameter increases in such manner that the relation between place of delivery of the hot strip with respect to the winding apparatus remains constant. Preferably the annulus forming apparatus is combined with a continuous casting apparatus whereby the formation of the strip and the forming of the annulus take place at the same speed.

Abstract: A method for jointing two pipes such as an aluminum pipe and a copper pipe by friction welding. The aluminum pipe is inserted into a bore of a ring made of a heat resistant material, the bore having a straight section and a tapered section continuous from the straight section. The copper pipe has a tapered end peripheral surface. The copper pipe is pressed at its tapered end, in a rotating state, against the end of the aluminum pipe so as to expand the latter. As a result, an ironing is effected on the aluminum pipe by the straight section of the bore of the ring, such that the aluminum pipe overlies the straight section of the copper pipe in close contact with the latter. Consequently, the tapered surface of the copper pipe is friction welded to corresponding portion of the aluminum pipe while the latter is being backed up by the tapered section of the bore of the ring.
