Abstract: A valve is provided that comprises a valve body including an inlet, an outlet, and a check valve chamber having an opening through the side of the valve body. The valve has a cover secured within the side opening in the valve body. A first valve opening is disposed between the inlet chamber and outlet chamber. A control valve is movable relative to the first valve opening to regulate fluid flow through the first opening when fluid flow is in the inlet-to-outlet direction, and is movable to engage the first valve opening to restrict fluid flow in the outlet-to-inlet direction. The valve comprises a second valve opening disposed between the check valve chamber and the outlet chamber. A check valve member is movable relative to the second valve opening to restrict forward flow and permit reverse flow through the second valve opening.

Abstract: A lifting device for raising a load intended for support by a roof of a building utilizing a ladder. Device includes a sled having first portion for slidingly contacting the ladder and a second portion providing a platform for a load. The sled is movable along the ladder generally in an up and down direction. A brace member connects to the ladder end, adjacent the roof. The brace possesses a flange which contacts the roof. An arm rotatably connects to the brace. The brace arm includes a first support surface for the sled when the arm is rotated toward the roof and a second support surface for contacting the roof. The sled is motivated along the ladder by motivating mechanism such as a crank operated cable.

Abstract: An access port for loading single tape cartridges into and retrieving single tape cartridges from an automated tape cartridge library system. A door is rotatably mounted in an opening in an exterior panel of the library system. The shape of the door is designed so that the opening is blocked at all times, regardless of the position of the door. A tape cartridge tray is mounted on the rear side of the door, slanted downward at a ten degree angle. The downward slant of the tray enables the robot to accurately find tape cartridges placed therein and restrains the tape cartridge from accidental dislodgement. A latch mechanism is provided to prevent the door from rotating when the robot is operating near the access port. The latch has an actuator preventing unlatching of the door. The actuator is activated by the operating system when it is safe to rotate the door. A tape cartridge is inserted into the tray and the actuator is activated to unlatch the door.

Abstract: A magazine for handling a plurality of tape cartridges. The magazine includes a plurality of vertically spaced, parallel shelves having tapered front edges with notches formed therein for ease of tape cartridge insertion. The slots slant downward to precisely position and restrain the tape cartridges magazine. A rib extends through each slot to engage in a tape cartridge notch. Improperly inserted tape cartridges will be forced to extend further out of the magazine so that they will be easily identified. A handle formed on the upper end of the front face of the magazine causes the lower end of the magazine to pivot forward to restrain the tape cartridges from accidental dislodgement. A locking strap is also provided to prevent the tape cartridges from accidentally dislodging from the magazine.

Abstract: An electrical connector device (10) is provided in which a first member (15) of dielectric material defines a four-sided recess having a bottom wall (20) and side walls (16), and a second member (24) of dielectric material which can fit inside the recess with its edges (25) spaced a predetermined distance from the side walls (16) of the first member (15). Tab portions (31, 32, 44, 45) of one or more flexible circuits (11, 12) are bent around the side walls (16) of the first member (15) and frictionally held between the wall (16) of the first member (15) and the edge (25) of the second member (24). Exposed conductors (29, 49) of the flexible circuit (11, 12) on the outside of the wall (16) can mate with conductors (75) in a socket connector (13). Alignment means (19, 26, 73) are provided to align the flexible circuits (11, 12) with the members ( 15, 24) of dielectric material and to align the latter two members and frictionally hold them together.

Abstract: Boards of a first group of mutually parallel circuit boards (200,206) are directly connected to boards (27a,22b) of a second group of mutually parallel circuit boards by interfitting hermaphroditic connectors (24,26,28,30) mounted on edges of the boards. The boards of one group are all perpendicular to the boards of the other group and are positioned in edge-to-edge relation. Each board has a plurality of hermaphroditic connectors secured to its edge, with each connector adapted to mate with an identical hermaphroditic connector secured at an edge of a board of the second group. The hermaphroditic connectors are each substantially U-shaped (24,26,28,30) in one embodiment and J-shaped (126,128,130) in another embodiment.
