  • Patent number: 5816410
    Abstract: The present invention is a shipping container for safely storing articles such as semiconductor wafers. The shipping container has two sidewalls sealingly connected to two end walls to form a generally rectangular interior wafer confinement area. A top cover and a bottom cover are removably attached to the container to protect the wafers during shipping and storage and provide access to the wafers for processing. The wafers are securely held in place in the carrier by a cushioning means to prevent damage to the wafers. Furthermore, the wafers are locked into place to prevent contamination by the wafers generating particles in the wafer confinement area by rubbing against the carrier. The cushioning means for accommodating the flexing of the cover supports and suspends wafers in the wafer confinement area. The cushioning means extends from the top cover and has a plurality of wafer engaging edges. Each edge is formed in a convex arcuate shape with respect to a centerline of the carrier.

  • Patent number: 5803695
    Abstract: A grain distribution apparatus and method is disclosed for positive positional control of the providing distribution of grain among a plurality of receiving ducts. A housing contains a distribution spout rotated by a drive motor among discharge positions at each receiving duct. A control wheel connected to the spout rotates with the spout to a selected discharge position. The control wheel has a plurality of sensible code clusters and position proof windows, one of each for each discharge position. Each code cluster has a unique series of data digits and a series of sequencing digits adjacent the data digits. The data digits and sequencing digits are serially read by a sensor. The sensor is connected to a control processor for identifying the position of the spout. The control wheel is configured as a driven sprocket and is engaged by the upper portion of a double wide roller chain around the entire periphery of the control wheel.

  • Patent number: 5801128
    Abstract: A dry Non-Oil metalworking lubricant that can be applied by a hot melt application. This dry lubricant is completely water soluble, provides rust protection, cleans from surfaces with plain room temperature water, and is more environmentally safe than other lubricants. A polyethylene glycol of sufficiently high molecular weight to be solid at room temperature is combined with amines, rust inhibitors, and metalworking additives to produce a thin film that provides protection for the part and the tooling in a metalworking operation. This lubricant provides further benefits to the overall process such as; easy to clean, weld through capability, excellent paint system compatibility, and environmentally superior to other lubricants.

  • Patent number: 5778767
    Abstract: A dispenser for dispensing a predetermined quantity of food articles, such as frozen french fries, frozen chicken pieces, cheese sticks, and the like, having a support structure supporting a hopper, the hopper having a storage area positioned over an exit opening and a dispenser drum between the storage area and the exit opening. The dispenser drum is rotatably mounted in the hopper between two end walls on the hopper. The dispenser drum has an axis of rotation, a sealing lip at a first radius perpendicular to the axis of rotation and a catching lip at a second radius perpendicular to the axis of rotation. The second radius is longer than the first radius creating a non-cylindrical shaped dispenser drum. A diverter is pivotally mounted in the hopper. The diverter is positioned to be bumped by the dispenser drum to jostle food articles in the storage area. A driver portion is mounted on the support structure to engage and rotate the dispenser drum about the axis of rotation.

  • Patent number: 5762293
    Abstract: A two-piece inflatable kite is made from configured, mirror imaged top and bottom polyester films which are heat sealed about their peripheral edge. Integrally extending from the edges forwardly and rearwardly are string connecting tabs formed from the top and bottom films. The tabs support reinforced apertures for attaching the kite string bridle. The top and bottom film portions also form a valve for adding air into and out of an air tight compartment within the kite. The air tight compartment also forms the wings of the kite.
