摘要:
A panel member has a three dimensional pattern thereon, and the panel member is shaped using a die having at least one substantially smooth side. A portion of the panel member having the three dimensional pattern thereon is pressed adjacent the substantially smooth side of the die with a force sufficient to reshape the portion of the panel member so that the portion of the panel member has a major surface that is substantially void of the three dimensional pattern. The shaping and pressing are performed in a single pressing step.

A system having a multiple-mirror ring-down cavity with one mirror where light may be input into the cavity and light from the cavity may be detected. A valve may permit light to enter or not to enter the cavity. An amplifier may be connected to a detector for detecting light from the cavity. The amplifier may be off or set at a low gain when light is entering the cavity and be on at a medium or high gain at a time when light is not entering the cavity.

Auxiliary content not associated with programming content is provided to a content presentation device by at least one content provider. Similarly, programming content comprising detectable indicia is likewise provided by at least one content provider to the content presentation device. Prior to or during output of the programming content to a user, the content presentation device detects at least one detectable indicia in the programming content and inserts at least a portion of the previously received auxiliary content into the programming content. The auxiliary content may be filtered according to user information and selected for insertion into the programming content based on insertion criteria. Both the auxiliary and programming content may be provided by a single content provider or each may be provided by a different content provider. Because the content presentation device handles insertion of auxiliary content into programming content, more targeted presentation of auxiliary content is possible.

A bending brake for sheet material includes frames; an upper jaw and a lower jaw that cooperate to hold the sheet material a bending surface pivotally connected to the lower jaw to bend the sheet material against an anvil of the upper jaw; an interlocking unit connected to the frame and having a cam surface which has having a locking position; and an elongated pipe assembly for rotation by a user. The elongated body bears against the cam surface and rests in the locking position to clamp the sheet material with reduced freedom of play.

A hide-a-nail sliding strip is described comprising a combination washer and spacer device and a sliding L-connector. The washer/spacer is embedded in an elongated slot on the face of the L-connector, allowing the connector to freely move. Double-sided tape and a tack are also provided on the L-connector. When applying vinyl trim, a nail is first inserted through the washer and the hide-a-nail strip is secured. A strip of vinyl trim is then pressed against the tape and tack. The sliding strip decreases pinching the trim and allows for expansion and contraction due to temperature changes, thus decreasing rippling or buckling.

A connector that receives a threaded apparatus and reduces stresses induced from the treaded apparatus into the connector is described. The connector includes a top side, a bottom side, and an opening that extends therethrough. The opening is defined by an inner surface that includes a threadform including a plurality of threads. The threads extend radially outward from the inner surface into the connector opening and include a first thread portion and a cutback that extends through a portion of the threadform. The cutback facilitates less stresses being induced into the first thread portion.

A door and floor molding which includes a stationary piece and removable piece. When used as a door molding, the stationary piece is attached abutting a doorway or window and when used as a floor molding is attached a distance above the floor. The distance above the floor is dependent upon the width of the mid section of the removable piece. A lip of the removable piece extends above the mid section and is slideably engaged within a clamping pocket of the stationary piece. A stabilizing wall of the removable piece lies substantially perpendicular to the lip and extends on both sides of a plane of the lip. The stabilizing wall engages the wall in a manner so as to press the mid section against the stationary piece and provide a more secure fit. The removable piece may be removed from its position within the stationary piece to aid in painting around or running wires through the molding.
摘要:
A coupling arrangement for coupling a guard post to a scaffold platform. The couples includes a brace for attachment to the guard post. A plug member is carried by a portion of the brace and extends perpendicular to the post. The plug includes a resilient sleeve through which extends a bolt. The bolt passes externally of the brace for external manipulation thereof. The plug member is inserted into a hollow run of the scaffold. The bolt is tightened, whereby the sleeve becomes constructed and secures itself within the rung.

A mobile scaffolding system having a substantial rectangular rolling base which supports pump jack poles on which rides up and down pump jacks across which a platform is supported. The poles are supported by extensible supports when moved to a desired location and when a user mounts the platform, the poles extend downward to lock onto the support surface stabilizing the base and preventing further movement of the base.
