Abstract: A method of efficiently delivering replacement railway ties for use in replacing ties that have deteriorated. GPS technology is used to obtain the GPS location of each tie that needs to be replaced. A tie train carrying replacement ties has a GPS monitor so that one or more ties can be unloaded at or near the location of each tie that requires replacement. A tie replacement crew can use a GPS monitor to locate each tie that requires replacement, and the crew can remove those ties and install a nearby replacement tie.

Abstract: A welded wire reinforcement is used in combination with insulated concrete form blocks having opposed panels joined by form ties. A method of construction forms building structures with insulated concert form blocks. The reinforcement member has a base bar and a plurality of arms extending downwardly from the base bar and is utilized to provide increased internal strength to a modular concrete wall system. The welded wire reinforcement provides vertical and horizontal support without requiring any extra time or material to connect a vertical reinforcement to the concrete forms of the wall system. An alternate embodiment of the reinforcement member includes a horizontal base bar, arms extending downward and perpendicular from the base bar, and a plurality of end pieces attached to the arms to form a discontinuous bottom bar. The base bar and bottom bar are slidably received in rebar chairs defined by the form ties.

The liner installation ring is disposed in the cylinder block or the cylinder liner in such a manner that the bottom face of the liner installation ring face to the uppermost portion of the cylinder liner. The liner installation ring is disposed at a position in accordance with the upper end position of the top land portion when the piston reaches a top dead center. The liner installation ring is set to protrude from the inner periphery of the cylinder liner in an inward direction at a length of 0.05 mm or more to 0.5 mm less.

Abstract: Mechanical assembly comprising a roller chain mounted on multiple sprockets attached via shafts and bearings to a frame. Multiple unloader shackles are attached to the roller chain such that all shackles are aligned in a consistent manner. The roller chain assembly is mounted in such a way as to align it longitudinally with an overhead shackle-line. It is mounted in such a way as to allow the individual unloader shackles to align directly opposite the individual overhead shackles at a specific offset distance and travel in the same direction as the overhead shackles. It is also mounted in such a way as to allow the attached shackles to rise in elevation from beneath the overhead shackles as they travel in the same direction as the overhead shackles. The chain is driven at a rate which synchronizes the attached unloader shackles with the overhead shackle-line to which it is aligned in order to transfer a carcass such as a leg quarter.

Abstract: The present invention relates to a III-nitride semiconductor light emitting device comprising a plurality of III-nitride semiconductor layers including an active layer emitting light by recombination of electrons and holes, the plurality of III-nitride semiconductor layers having a p-type III-nitride semiconductor layer at the top thereof, a SiaCbNc (a?0,b>0,c?0) layer grown on the p-type III-nitride semiconductor layer, the SiaCbNc layer having an n-type conductivity and a thickness of 5 ? to 500 ? for the holes to be injected into the p-type III-nitride semiconductor layer by tunneling, and a p-side electrode formed on the SiaCbNc layer. According to the present invention, a SiaCbNc (a?0,b>0,c>0) layer which can be doped with a high concentration is intervened between a p-type nitride semiconductor layer and a p-side electrode. Therefore, the present invention can solve the conventional problem.

Abstract: A method and apparatus are provided for editing video sequences.

Abstract: A quick release system for releasing armor plates from a vest or other garment including a pocket associated with the front torso portion of the vest for selectively receiving a first armor plate, a pocket associated with the rear torso portion of the vest for selectively receiving a second armor plate, and a flexible retainer element in conjunction with at least one connector element associated with each of the front and rear pockets for selectively retaining the first and second armor plates therewithin, pulling the flexible retainer element releasing the armor plates from their respective pockets. A release handle is located on the front of the vest and is attached to the retainer element for facilitating pulling of the retainer element to release the front and rear armor plates in one easy motion.

A first print head is mounted in a vertically pivotable manner and a second print head is mounted in a non-pivotable manner.

Abstract: The invention is a post-operative binder designed primarily for female patients made of relatively elastic and padded material. The present invention is designed to put pressure on the Pfannenstiel incisional area to prevent swelling through the use of a primary fastener and cross straps. Cross straps are fixedly attached to the midline section of the binder and removably attach to the sides of the binder at an angle to apply the appropriate pressure to the incisional area. The invention is designed with pockets to accommodate hold hot or cold packs in the incisional area, pain relief devices, sandbags or other hard or soft support structures to apply additional pressure, or drainage receptacles.

Abstract: The use of monofilament line to form a grid in the cross stitch fabric corresponding to the grid in a cross stitch pattern to facilitate the cross stitching process, after which the monofilament line can be easily removed by pulling from either end. The monofilament line has the distinct advantage of being resistant to piercing by the needle and cross stitch thread during the cross stitching process, and thus not being woven into the design as guide thread would do.
