The present invention provides a duplex electrical connector comprising a housing and an insert in the housing that provides two inbound end apertures that conduct two armored cables to and through a single outbound end aperture. The duplex electrical connector of the present invention incorporates the snap in spring steel retainers of to provide a connector that allows rapid and simplified installation of a pair of armored cables into a single junction box outlet. The two inbound apertures each...

A strainer for trapping solid particles entrained in a fluid flowing through the strainer includes a two-chambered housing, each chamber containing a removable strainer basket. The strainer also includes a plurality of valve mechanisms for routing fluid flow through the two chambers in a predetermined manner. A user actuated directional flow control valve includes a multi-ported ball member rotatably supported by and between a pair of opposed valve seat plates, each associated with a respective ...

A duplex strainer having a housing with an inlet port and a outlet port. st and second strainer chambers each have first and second ports which are in separate fluid communication with the housing. An efficient scotch yoke design coverts rotation of a first shaft into reciprocal lateral displacement of first and second disk assemblies to permit either the first or second strainer chambers to be closed off to flow while the other of the first and second strainer chambers remain open to flow.

A duplex envelope includes a face sheet divided into a top page, bottom page, inner flap, and outer flap. A complementary liner is divided into a pocket bonded to the bottom page to define an inner envelope, an inner tab removably bonded to the inner flap, and an outer tab removably bonded to the outer flap. The top page is foldable over the liner pocket for defining an outer envelope closed by the outer flap.

A duplex conveyor comprises a pair of relatively spaced parallel bars having mutually facing sides with a plurality of bearing blocks mounted for displacement along each bar. A support roller is rotatably journalled for rotation relative to each bearing block and the support rollers are adapted to underlyingly support a workpiece carrier. The bearing blocks have lateral guide surfaces for cooperatively engaging a workpiece carrier during movement thereof upon rotation of at least one of the supp...

A stainless duplex ferritic-austenitic steel with improved corrosion resistance. The steel consists essentially of about: 0.03 w/o Max. carbon, 3.0 w/o Max. manganese, 1.0 w/o Max. silicon, 26.0 to 29.0 w/o chromium, 3.5 to 5.2 w/o nickel, 3.5 w/o Max. molybdenum, 0.15 w/o Min. nitrogen and the balance essentially iron. The steel preferably contains about 0.17 to 0.35 w/o nitrogen for improved pitting resistance and for increased austenite content. Welds of the steel preferably contain at least ...

An arrangement for multi-standard duplex filtering for mobile terminals in a telecommunications system. The arrangement includes a substrate on which a first array of filter elements and a second array of filter elements are formed. The filter elements have different frequency bands in accordance with mobile telecommunications standards. The first array filters an incoming signal received from an antenna and provides an output at port in accordance with a matched frequency band of one of the sta...

A duplex connector system is provided for coupling two individual simplex fiber optic connectors in a side-by-side alignment. Each fiber optic connector includes a housing in which an optical fiber cable is terminated through a rear end of the housing. First and second strain relief boots are respectively interengageable with the housings of the connectors at the rear ends thereof and encompass the optical fiber cables. Resilient portions interconnect the first and second strain relief boots and...

A duplex strainer for straining material includes a housing, housing inlet port through which material enters the housing under pressure for straining and an outlet port through which strained material exits the housing. The housing includes a first strainer chamber having the first and second ports in separate fluid communication with the housing. A second strainer chamber includes third and fourth ports in separate fluid communication with the housing. The first port opposes the third port and...

A copier for duplex copying in which blank sheets are fed from a copy sheet tray (41) to a photoreceptor (11) to receive a first image on one side and the simplex copy sheets so formed are conveyed to a duplex buffer tray (43) from which they are refed to the photoreceptor to receive a second image on the other side. The buffer tray (43) is arranged so that the simplex sheets are inserted into it lead edge first in the same direction (right-to-left) in the drawing in which they leave the photore...
