Cam driven paddle assembly for a plating cell

Abstract: The present invention overcomes the drawbacks and limitations described above by providing a paddle assembly having a paddle that moves in a bidirectional fashion for agitating solution in a container of a plating cell. A follower is coupled to the paddle. The follower engages a rotatable cam and is propelled along the cam as the cam rotates. A drive mechanism rotates the cam.

Integrated circuit packaging system with protective coating and method of manufacture thereof

Abstract: A method of manufacture of an integrated circuit packaging system includes: forming a lead-frame having a die attach paddle and a contact pad connected by a link; mounting an integrated circuit die over the die attach paddle; molding a package body on the lead-frame and the integrated circuit die including leaving portions of the die attach paddle, the contact pad, and the link exposed from the package body; forming an exposed edge by etching away the link between the contact pad, and the die attach paddle; and depositing a solder-resistant layer on the exposed edge.

Dual nozzle single horizontal actuator ink jet printing mechanism

Abstract: A nozzle arrangement for a printhead comprises nozzle chamber walls that define a nozzle chamber having at least two fluid ejection ports. A moveable paddle vane is located in a plane adjacent a rim of a first one of the fluid ejection ports. An actuator mechanism is attached to the moveable paddle vane and is adapted to move the paddle vane in a first direction so as to cause the ejection of fluid drops out of the first fluid ejection port and to further move the paddle vane in a second direction so as to cause the ejection of fluid drops out of a second fluid ejection port. Preferably, the nozzle arrangement further comprises a baffle located between the first and second fluid ejection ports so that the paddle vane moving in the first direction causes an increase in pressure of the fluid in the volume adjacent the first port and a simultaneous decrease in pressure of the fluid in the one volume adjacent the second port first one of the fluid ejection apertures such that, while ink is ejected from the second fluid ejection aperture, the meniscus of the first fluid ejection aperture and the at least one smaller aperture are interconnected within the nozzle chamber. Preferably, each aperture can include a ribbed rim around the outer surface thereof.

Stamped arm control

Abstract: A control arm includes a first clamshell half and a second clamshell half, a ball joint housing, and a paddle portion. The paddle portion is formed as a single piece with the ball joint housing, has a first side and a second side, and is disposed between the first clamshell half and the second clamshell half. A first weld connection may join the first clamshell half to the first side of the paddle portion, and a second weld connection may join the second clamshell half to the second side of the paddle portion. Attachment of the first clamshell half to the first side of the paddle portion and attachment of the second clamshell half to the second side of the paddle portion may be characterized by the absence of a rivet and a bolt.

Human-powered watercraft paddle propulsion system

Abstract: A human-powered, foot or hand operated paddle propulsion system for a variety of differently sized and configured watercraft. A rigid supporting subframe attaches the system to an end of the watercraft. A spaced-apart terminus is wedged towards a boat seat base. The terminus and subframe cooperatively secure the system within the boat. The subframe has a C-shaped bow plate coupling it to the boat end. The paddle assembly is removably quick-connected to the bow plate. Knobbed, slidably adjustable mounting bolts captivate the subframe upon the bow. The frame comprises a pair of adjustable, telescoping frame beams that enable it to retract or extend. The frame supports an adjustable actuating assembly including foot-operated pedals and optional hand bars for powering the boat. Cabling links the actuating assembly to the drive paddle assembly. Slidable captivation of the activating assembly upon the frame facilitates cable length and tension adjustments. The cabling extends through the frame and around the drive paddle assembly between terminal ends on each foot pedal. The subframe buttresses the drive paddle assembly. The drive paddle assembly controls paddle pitch and sweep. A spring lock may be used to lock a cable guide donut in a selected pitch-controlling position. The lock maintains donut positioning until released.
