A substrate processing pallet has a top surface and a plurality of side surfaces. The top surface has at least one recess adapted to receive a substrate. The recess includes a support structure adapted to contact a portion of a substrate seated in the recess and a plurality of apertures each adapted to accommodate a lift pin. Lift pins can extend through the apertures initially to support the substrate and retract to deposit the substrate onto the support structure. A side surface includes a pro…

The invention concerns a two-stroke internal combustion engine supplied with gasoline, diesel, fuel, or other conventional fuel comprising a piston (2)-cylinder (1) assembly, said cylinder (1) providing exhaust ports (11), said piston (2)-cylinder (1) assembly providing a head (5) slidable within said cylinder (1) between the Top Dead Centre of the piston (2) stroke and a closure position of the exhaust ports (11), said slidable head (5) providing a transfer valve (9) for fresh air or fresh air-…

A method and system for mapping nodes in an M.times.N torus interconnection fabric of nodes is provided. The method includes generating an observed mapping of the nodes in the interconnection fabric showing a location of a first node relative to an x-axis of the fabric and relative to a y-axis of the fabric, comparing the observed mapping of the nodes to a set of expected mappings, and identifying the expected mapping which is most similar to the observed mapping.

A suspension board with circuit includes a metal supporting board, an insulating base layer formed on the metal supporting board, a conductive pattern formed on the insulating base layer, an insulating cover layer formed on the insulating base layer so as to cover the conductive pattern, and an optical waveguide.

A padded corner bumper comprises an elongated core formed of a cushioning material, an outer decorative cover formed of vinyl-coated fabric, and a backing material formed of polypropylene mesh. The core has a front, a back coextensive with the front, and a continuous side edge extending between the top and bottom. The outer decorative cover and backing material are stitched together to form a casing that completely surrounds the core, the backing being positioned only over the back of the core. …

The invention relates to a plate-type heat exchanger comprising a stack of double-walled heat exchanger plates (30 32) which are permanently interconnected and each include two plate members (33, 34) having a central heat transfer portion (35) and an edge portion (36) bent upwardly with respect to the plane of the central heat transfer portion (35), separate flow passage spaces for at least two heat exchange fluids being defined between the double-walled heat exchanger plates (30 32), the two pl…

A system for allowing a shoe wearer to lean forwardly beyond his center of gravity by virtue of wearing a specially designed pair of shoes which will engage with a hitch member movably projectable through a stage surface. The shoes have a specially designed heel slot which can be detachably engaged with the hitch member by simply sliding the shoe wearer’s foot forward, thereby engaging with the hitch member.

This invention pertains to novel fibers made of .alpha.(1.fwdarw.;3) polysaccharides, and a process for their production. The fibers of the invention have “cotton-like” properties but can be produced as continuous filaments on a year-round basis. The fibers are useful in textile applications.

The present invention discloses apparatus and methods for a lightweight subsea intervention package that may be installed using vessels with a smaller lifting capacity than semi-submersible platforms so that the subsea intervention package can be transported, installed, and removed from a subsea well in less time and with less cost. In one embodiment, the present invention comprises a lower riser package for controlling the subsea well which utilizes two hydraulically activated gate valves. An e…

An exercise device (10) has foot supports (30, 32) on which a user stands for performing a stair stepping exercise alone, or a cross country skiing exercise alone, or simultaneously a stair stepping exercise and a cross country skiing exercise. Linkage support frames (26, 28) each have a first linkage (44) and a second linkage (36) pivotally connected to each other for maintaining foot supports (30, 32) in a horizontal plane. A fluid cylinder (52) provides a mechanism for resisting the vertical …
