Abstract: A power transmission (10) chain-belt (32) is disclosed that is especially adaptable for connecting the pulleys (12, 14) of a pulley transmission (10). The chain-belt (32) has a plurality of interleaved sets (34) of links (36) and each set (34) has a plurality of transversely arranged links (36). Pivot members (40) join adjacent sets (34) of links (36) to form an endless loop. At least one toe (42A, 42B) extends from each link (36) in at least some sets (34) of links (36). At least the toes (42A, 42B) on adjacent links (36) are in opposed relationship and define a passageway 80. A plurality of load blocks (50) are connected to the links (36). The load blocks (50) are positioned in the passageway (80) defined by the toes (42A, 42B). Each load block (50) has edge surfaces (88) for contacting the pulleys (12, 14) of the transmission (10).

Abstract: Structural means are provided in an electron tube base for expeditiously controlling the flow of dielectric adhesive material relative to designated lead positions therein. This is accomplished by barrier means in the form of a centralized rim, extending from the crown portion of the base, which isolates the low voltage leads from the flow of dielectric material. In conjunction therewith, a trough-like channel is formed in the floor of the base flange to expedite flow of the dielectric material from the central cavity of the base to the vicinity of the high voltage leads.
