Abstract: A screen system having a plurality of screen elements that can be readily removed and replaced to vary one or more characteristics of the screen surface formed by the screen system. The screen system includes a support system for supporting at least one screen element to prevent deformation of the screen element that typically would occur due to the insufficient structural stability of the at least one screen element relative to the weight of the product being screened. Preferably, the support system includes one or more support elements that can be readily and easily installed and removed from the screen system. The support system is preferably configured to permit the one or more support elements to be positioned at different locations in the screen system. Preferably, the support system is configured to permit a variety of different support elements to be used to allow a greater variety of screen elements to be used.

Abstract: A purse seine link (10) having a roller head (30) attached to body (20) by head pivot (32). Latch mechanism (22) allows for one step release of roller head (30) to release cable (8).

Abstract: The base comprises a tubular housing adapted to fit over the exhaust tubulation of an electron tube stem, and a wafer flange extending outwardly from the open end thereof. The flange is apertured to receive an array of conductors of the stem. A recess is provided in the wafer flange facing the stem and a passageway communicating therewith is provided through the base separate from the housing cavity for the purpose of injecting a dielectric material into the recess around some of the stem conductors. The passageway may, e.g., be through the flange or in the housing wall.A shoulder is provided on the recessed face of the wafer flange to provide relief for random protuberances on the periphery of the stem to permit non-tilted mounting of the base on the stem.

Abstract: An electron-tube socket comprising a plurality of spring wires in a circular array, each wire including (i) a base portion adapted to be clamped in a fixed position within the socket, (ii) an extended portion terminating in a free end which extends towards the open side of the socket cavity and including a contacting section adapted for contacting a pin of the electron tube and (iii) a transitional portion connecting the base portion with the extended portion and adapted to urge the contacting section against the pin.

Abstract: A fixture for supporting and aligning the components of a rectangular cathode ray tube has a base, support means and three alignment structures. The supporting means tilts the tube with respect to the base so that the tube nests against the three alignment structures.
