Abstract: The method and apparatus for forming composite wood products particularly composite veneer like products which may be intermediate products and laminated to form the final composite product. Strands are fed from a source of supply at a metered rate, entrained in an air stream and carried along a confined path between an entrainment zone and the source of supply. Strands are condensed onto a surface to form a veneer lay-up of at least one layer of strands on the forming surface and this veneer lay-up is carried from the path and deposited onto a collecting surface and later consolidated into a composite product. Entraining air and strands not forming veneer are separated in the supply station, the strands fall onto the supply of strands and energy is added to the separated entraining air and it is returned to the entraining zone.
Abstract: A plug portion 23 which engages to a socket 13, to which a liquid transport hose and a gas transport hose 7 are connected, is provided to a plug 12 which closes an aperture portion which is formed in a container. A liquid conduit 26 on the side of the plug 12 which is communicated to a liquid conduit 56 on the side of the socket 13 is formed on the inner side of the plug portion 23, while a gas conduit 41 on the side of the plug 12 which is communicated to gas conduits 52 and 63 on the socket side is formed on the outer side of the plug portion 23. By this construction, it is possible to anticipate simplified and reduced cost manufacture for a connector which excels in convenience due to having a plurality of conduits.

Abstract: Methods and apparatus for detecting polynucleotide hybridization in luminescence-based assays. The methods may include (1) contacting a sample polynucleotide with a reference polynucleotide at an assay site, where at least one of the polynucleotides is capable of emitting luminescence, (2) illuminating the assay site with light capable of stimulating such luminescence, (3) detecting light transmitted from the assay site, and (4) deriving information relating to the extent of hybridization between the sample and reference polynucleotides based on the detected light. The methods may further include (1) illuminating with and/or detecting polarized light, (2) deriving information relating to the sequence of the sample polynucleotide from the extent of hybridization, and (3) converting the light to a signal and distinguishing between a portion of the signal attributable to luminescence and a portion attributable to background.

In some embodiments, the flow-restricting device includes a body and a rotatable core.
Abstract: A portable outdoor cooker for cooking foods is provided. The cooker comprises a substantially circular heat transfer plate, a plurality of individually controllable burners disposed beneath the heat transfer plate, and a frame assembly for supporting the heat transfer plate and burners above the ground and in relation to one another. The heat transfer plate has a center and a perimeter, and includes a cooking surface. The plurality of burners includes an inner burner and an outer burner, the outer burner being positioned adjacent the perimeter of the heat transfer plate and the inner burner being positioned closer to the center of the heat transfer plate than the outer burner such that the cooking surface can be made hotter adjacent the perimeter of the heat transfer plate than adjacent the center of the heat transfer plate.
Abstract: A keyboard overlay that may be adjusted to fit over a variety of keyboards. The overlay is self-supporting so that potential damage to the keyboard is limited, and requires no straps or other retaining devices so that removal and replacement of the overlay is simple. It is particularly intended for use by young children. The overlay includes a support having telescoping crossbeams configured to permit adjustments for keyboards of varying sizes.
Abstract: A plural-layer body-contacting cushioning interface structure which is interposable the human body and an external structure, such as a helmet. The cushioning structure of the invention, in one preferred form, has a body-facing side which contacts the body, and a load-facing side which contacts the mentioned external structure. Intermediate these sides is a moisture-wicking layer which is designed to contact, and draw moisture away from, the body, a continuous, moisture-blocking, gas-permeable barrier layer adjacent the moisture-wicking layer, and an acceleration-rate-sensitive cushioning structure disposed protectedly within the barrier layer which fully encapsulates the cushioning structure.
Abstract: A joint support is attachable to a limb of an animal to limit movement of an associated limb joint substantially about a single axis. The joint support includes a radial element having a longitudinal axis and a transverse element having a longitudinal axis. The transverse element is pivotally connected to the radial element about an axis of rotation. The longitudinal axis of the radial element substantially intersects with the axis of rotation, and radial rotation of the radial element is restricted about the axis of rotation. The longitudinal axis of the transverse element is partially fixed relative to the radial element so that the same is substantially coplanar with the longitudinal axis of the radial element and substantially offset from the axis of rotation.
Abstract: A connector 20 comprises a plug 21 fitted to an opening 2 formed in a container 1, and a socket 22 which is connected to the plug 21. The plug 21 comprises a bracket section 3 which is fitted into the opening 2 of the container 1, and a plug section 23 which is screwed into a threaded aperture 4 formed in the bracket section 3. An annular locking ring 63 formed with lugs 66 on the outer periphery is integrally but removably fitted to the plug section 23 which is threadedly attached to the threaded aperture 4. A plurality of engaging ribs 67 are formed on the inner peripheral face of the bracket section 3 for preventing rotation of the plug section 23 by engaging with the lugs 66 of the locking ring 63 which is fitted to the plug section 23. As a result, loosening from the threaded aperture 4 of the reusable plug section 23 which is removable by threading into the threaded aperture 4 of the bracket section 3, is prevented so that leaking of the liquid inside the container 1 from a loosened part is prevented.
