Abstract: The bracket includes an inner body having a hook on one end and arranged to slide within an outer body having a hook on one end to provide a variable bracket length. A pair of springs located between overlapping portions of the bodies biases the bracket towards its longer uncompressed length. After the bracket is mounted to a support surface, a wall of the headrail is hooked onto the hook of the inner body. The headrail is then advanced to compress the springs and shorten the bracket length so that an opposite wall of the headrail can catch on the hook of the outer body. Removing the compression force on the springs biases the bracket toward its longer length to capture the second wall of the headrail with the hook of the outer body. By this arrangement, an easily applied pushing force installs and attaches the mounting bracket to the headrail.

Abstract: A mounting arrangement includes a multi-functional arm mounted in a mounting receiver.

Abstract: An improved electrically operated pilot-type, “instant-on” solenoid assembly for near-instantaneous control over the flow of compressed gas. The assembly may be applied in fuel systems for propulsion in vehicles using gaseous fuel. It includes a housing with inlet and outlet passages connected to a primary chamber where a primary piston is slidably mounted, a secondary chamber having a secondary piston slidably mounted within the chamber, a solenoid to produce translational movement of the pilot piston, and passageways linking the various components.

Abstract: A movable sheet separating unit is pushed all the time by a lifting spring in a direction toward a feeding roller. In a non-feeding state, a sheet lifting plate is engaged with an operating fraction so that the movable sheet separating unit is held in a standby position where a separating pad is separated from the feeding roller. In a feeding state, the sheet lifting plate rises and disengages from the operating fraction so that the movable sheets separating unit moves to a pressing position where the separating pad is pressed against the feeding roller. In the pressing position, the separating pad is pressed against the feeding roller via a rotatable support base by a pressing spring, and is displaced by rotation in a direction away from the feeding roller in accordance with a thickness of a sheet S passing through between the separating pad and the feeding roller. Thus, durability of the separating pad can be improved, and a feeder suitable for a fixing type feeding cassette can be provided.
