Abstract: A support member for a concrete structure comprises a T-shaped insert defining a T-shaped internal volume. A nut is inserted in the transverse portion of the internal volume and end caps are placed over the ends of the insert to fully seal enclose the internal volume. The insert is then placed within a form for a concrete structure such that the base surface of the T-shaped insert will be coplanar with a surface of the concrete after the concrete has been poured into the form and set. The base wall of the insert is then removed, thus exposing the T-shaped volume. The distal end of a bolt can be inserted into the insert and fixed to the nut. The proximal end of the bolt extends out of the insert and beyond the surface of the concrete and can be attached to equipment or other structure which is to be supported on the concrete structure.

Abstract: The invention disclosed is a stacked, permeable membrane assembly, comprising two clamping plates with spaced, permeable membrane assemblies between them on a simplified frame. Each membrane assembly includes a membrane support means, conveniently a rigid screen, covered by a pair of membranes. The frame is designed to retain the membrane-covered support in internal grooves. Additional membrane support plates and sealing collars are not required.

Abstract: An improved anchor for embedment in a concrete member to provide a lifting attachment for the member. The anchor comprises an elongate bar having convergent and divergent surfaces wherein the divergent surfaces face outwardly to direct axial pull-out forces imparted to the bar divergently and laterally into a concrete member within which the anchor is embedded. Divergent wings are fixed to and extend laterally from the bar to direct lateral forces imparted to the bar in divergent directions relative to the bar.

Abstract: An adaptor bar is disclosed for removably coupling in fixed relation a pair of single anchor inserts used in casting concrete, thereby forming a double anchor insert. The anchor inserts are used as permanently installed lifting points in the construction of tilt-up concrete walls and the like. The adaptor bar includes T-shaped cutouts in each end which cooperate with reliefs in an elongated anchor member of a single anchor insert to allow the adaptor bar to releasably engage an elongated anchor member at each end. The inventive adaptor bar provides for an inexpensive double anchor and allows the user to only stock single anchors without the need to have a separate inventory of double anchors as well.

Abstract: An attachment for a conventional pry bar facilitates the bar for use in the pulling of stakes. The attachment comprises a section of pipe which is flattened to provide a tubular portion telescopically receivable over the end of a pry bar and thin edge portion to one side of the tubular portion. The edge portion is formed with a notch proportioned for slidable receipt around a stake to be pulled and gripping engagement with the stake upon cocking of the attachment relative to the stake. In use the stake is cocked for gripping and pulling engagement with the stake by fulcruming the pry bar against a surface adjacent the stake.

Abstract: A system and method for upgrading a computer is disclosed. Certain essential chips present in the original computer system are functionally, but not necessarily physically, removed from the computer system. Functions which would otherwise be performed by the original chips are instead performed by higher-performance chips on a plug-in module which is plugged into the computer system. The functional removal of the certain chips from the original computer system is achieved through simple insertion of the plug-in module. No replacement or substitution of original chips or boards is necessary. Furthermore, upgraded computer systems may be further upgraded by replacement of a first plug-in module with a second plug-in module with different performance characteristics.

Abstract: An improved insert anchor assembly which provides a lifting clevis is disclosed. A novel void former comprising a body and plug to completely surround the lifting clevis is also disclosed. An improved hoisting attachment capable of complimentable receipt within the recess created by the void former is further provided.

Abstract: A wall brace includes an elongated main brace that has a mounting bracket at one end for securing to a wall panel and a mounting bracket at the other end for securing to a floor. The wall brace further includes two lateral bracing legs each pivotably coupled at one end to the center of the main brace and each having a mounting bracket at the other end for securing that end of the lateral bracing leg to either the floor or the wall panel.

Abstract: The invention provides an eave truss for anchoring, supporting and reinforcing a metal roof and "tilt-up" or other prefabricated concrete or masonry walls in a building against the vertical load exerted by the roof itself, the lateral load exerted by wind and seismic forces, and load caused by thermal expansion and contraction of various attached heterogeneous building components. The eave truss is supported by the roof beams, and a single eave truss is attached to the roof, the ends of the roof beams, and the wall along the full length of each end of the building. The eave truss attachment to the wall is in shear only at the center portion of the truss; all other attachments to the walls from the eave truss are made through horizontally slotted holes in the eave truss to allow normal thermal expansion and contraction of the heterogeneous parts.

Abstract: Form panel supporting walers (32, 34) are secured in crossed relationship by an assembly having inner and outer right angle-shaped members (10, 12) engageable with opposite sides of the walers, and clamp means to draw the members toward one another. The clamp means comprise a bar (18) fixed to one of the members (10) and extending slidably through the other of the members (12), and a wedge (24) extending through the bar (18) for engagement with said other member (12).

Abstract: An anchor assembly for use in raising tilt-up wall sections which are cast in a horizontal position. The assembly includes an elongated steel anchor member supported in a vertical position on a base. A horizontal steel pin extends through an opening in the lower portion of the anchor member, with the pin and anchor member being retained in the base by two pairs of opposing resilient members which extend partially around the pin. A recess former is positioned over the upper end of the anchor member and is detachably locked to the anchor member by another pair of opposing resilient members which are extendable into a second opening in the upper portion of the anchor member. After the wall section is cast, the recess former is unlocked from the anchor member and removed from the wall section thereby providing access to the second opening of the anchor member.

Abstract: An assembly for anchoring an element to a concrete slab (10) through means of a bore (22) extending through the slab and a bolt (26) removably received within the bore (22). The bolt (26) has a laterally extending foot (28) engageable with one side of the slab (10). A tapered spike (30) having a length greater than the thickness of the slab (10) is extended through the bore (22) to force the foot (28) into underlying engagement with the slab (10) and maintain the bolt (26) in such engagement and secure the bolt (26) against rotation.
