Abstract: Method and systems for cleaning and wetting a semiconductor substrate, are provided. Methods and systems include forming an atmosphere in a basin housing the semiconductor substrate with a gas having a higher solubility in a wetting agent than oxygen. Methods and systems include spraying the wetting agent with a spray head onto the substrate while maintaining the atmosphere. Methods and systems include rotationally translating the semiconductor substrate, the spray head, or both the semiconductor substrate and the spray head, Methods and systems include wetting a plurality of features defined in the substrate.

Abstract: A method and system of cooling a server rack unit is described herein. A server rack for housing certain devices may be configured to receive a first air flow at a server rack front. Each device may form a wall at the back of the device creating a channel between the wall and the server rack back. The camber may collect warm air created by the first air flow as it extends over the at least one server. A first surface of the server may define at least one server rack opening allowing the warm air in the channel to exit the server rack.

Abstract: A conveyor system is provided to limit the vertical fall experienced by a product transported along the conveyor and falling into a collection bin. A sensor in a fixed position relative to the product conveying plane of the conveyor measures product collection height in a collection bin to produce an output signal. A controller dynamically varies the angle between the conveyance plane and the collection bin base plane and the vertical displacement therebetween within a preselected range in order to minimize product damage associated with different fall trajectories from the conveyor into the bin for product. Either the conveyor or the collection bin is pivoted under the command of the controller to accomplish the desired function.

Abstract: An adjustable chanter for mounting in an outlet tube of a set of bagpipes includes a conventional reed and a conventional chanter pipe having a series of finger holes by which notes can be selected. The chanter pipe has a collar at an upper end which is screw fastened to a hub defining a sleeve arranged which extends from the upper end of the chanter pipe into the tube of the set of bagpipes as a friction fit within the tube such that the hub is supported in the tube for receiving air through the tube from the bag for passing through the pipe for playing the notes. The position of the mouth of the reed relative to the holes in the chanter pipe is adjusted by a shuttle which slides longitudinally in the hub moved by a manually operable shaft projecting from the hub to one side and manually rotatable so that the reed can be adjusted to change tuning without rotating the chanter pipe or removing the chanter pipe from the tube of the bag.

Abstract: Methods are provided for monitoring particulate flow distribution throughout particulate collection systems that employ collection vessels such as hoppers and feeders. The collection vessels are positioned in a grid pattern, and the amount of particulate collected from a given collection vessel is recorded as associated with that collection vessel's position in the grid, so that the particulate flow distribution can be analyzed. By analyzing the flow distribution, faults in the collection system can be discovered and addressed. Methods are also provided to ensure proper functioning of the emptying of particular collection systems employing hoppers that discharge particulate into feeders.
