Abstract: A sliding positioning structure includes a seat, a first fastening body and a second fastening body. The first fastening body is movably assembled at the seat. The second fastening body is provided at the seat, and is for longitudinally fastening, latitudinally fastening or rotationally fastening to a first object. Accordingly, the seat can be quickly assembled with the first object by using the second fastening body, and be coupled with or removed from a second object by using the first fastening body, thereby accomplishing coupling or disengagement of two objects and achieving effects of repeated and quickly coupling and disengagement.

Abstract: Composite precast concrete panels are described herein having have an anchor that distributes forces imposed on the anchor through concrete wythes of the panels. Specifically, pins can be embedded in at least one concrete wythe, and then the anchor is secured to the wythe as described herein. The anchor extends through another Wythe to selectively connect to a hoist system that moves and places the composite precast concrete panel. The forces imposed on the anchor are distributed through the pins and into multiple concrete wythes to prevent failure of the composite precast concrete panels and improve safety.

Abstract: A roof hook for mounting of solar installation modules on roofs. The roof hook has a first fastening section, which extends in the X and Y direction for fixing a roof hook, a hook-shaped mount for fixing the solar installation module or a fastening profile for solar installation modules and a second fastening section which runs perpendicular to the first fastening section in the Z direction from the latter. The mount is adjustable on the second fastening section in the Z direction, and fasteners act obliquely to the Z direction for fixing the mount on the fastening section.

Abstract: A cleat is provided. The cleat includes, but is not limited to, a head, a shank, and a vertical slot formed through the head and a portion of the shank. The shank is connected to the head and has a pair of opposing planar faces and a pair of opposing short edges, a wide portion and a point. The edges are provided with at least one serration fixed relative to said wide portion.

Abstract: The disclosed system, device, and apparatus for a locking element generally includes a force device having a suitable shape to fit around a plurality of coupled elements. This re-usable force device reduces unwanted and unintended rotation of coupled elements. Disclosed features and specifications may be variously controlled, adapted, or otherwise optionally modified to realize improved locking function.

Abstract: A flat plate is used to cover a mounting hole in a masonry wall face and is held in place by a set of wire hooks. The hooks are able to slide into holes in the plate and catch onto the interior surface of the wall in order to hold a clearance hole in the plate concentrically with respect to the mounting hole. An anchor bolt is supported at the center of the mounting hole by the clearance hole in the plate while grout is poured into the masonry blocks thereby assuring that the bolt is positioned properly in accordance with building code.

Abstract: A fastener which including a probe having a shaft portion and a head to which is attachable a flexible strap, a receptacle affixable to a panel having a hole therethrough, and a spring for locking the probe in place when the probe is inserted into the hole. Upon insertion of the probe into or rotation of the probe in the hole of receptacle, the spring permits further insertion or withdrawal of the probe.

Abstract: This invention relates to a clip for securing a segmented panel, such as that of a combustor liner for a gas turbine engine, to the outer shell of the combustor, a clip characterized by having two distinctly different spring rates depending on the magnitude of the load which the clip must support.

Abstract: An insulation hanger for supporting a compressible insulation blanket upon a supporting wall which is formed of three pieces, the first of which is an end weldable stud welded to the supporting surface and upon which the blanket to be secured is impaled. The end weldable stud includes a plurality of annular grooves of reduced cross section providing a shoulder at the juncture between the groove and the body of the stud. A flat washer like blanket retainer is utilized which has a keyhole aperture which permits the retainer to pass over the stud through a larger hole to compress the blanket and thereafter to be moved translationally to an aperture of size approximating the groove to interlock the blanket retainer with the shoulder of the stud.

Abstract: A retainer assembly is disclosed for retaining insulation material or the like adjacent a surface, such as an interior furnace wall. The retainer assembly comprises a longitudinally-extending member or stud and a retainer member or washer mounted thereon. The stud includes at least one throat portion. The washer comprises a body from which two prongs extend to define a channel. The prongs are folded back so that as a throat portion of the stud passes therethrough, the folded-back portions are compressed. Upon passage of the throat portions through this zone of the channel, the compressed folded-back portions of the prongs are released from compression thereby retaining the stud within a second zone of the channel.

Abstract: A vehicle wheel cover includes a plastic cover body and an annular retention band which is secured to the cover body by a series of projections on a flange of the body being received through openings in the band. The material of the openings is formed into integral lanced tabs which engage shoulders of the projections. The axial extent of the openings is greater than that of the projections to permit axial adjustment of the cover body and retention band relative to each other. The band is provided with retaining fingers for retaining engagement of the cover on a vehicle wheel.

Abstract: A panel hanger assembly for attaching soft panels of insulation material to a structural surface, such as the metal wall of a furnace, the hanger assembly including an elongated stud member having one end for welding to the furnace wall and being pointed at the other end, the stud member being of generally rectangular cross-sectional configuration and having spaced apart pairs of opposed notches formed in the cross-sectional end walls, and a clip having an aperture therein, the first portion of the aperture being dimensioned to freely slidably receive the stud member thereon and the other portion of the aperture being longitudinal and adapted for slidably receiving the stud member at a notched area, the outer surface of the clip being configured to resist reverse lateral displacement of the clip relative to the stud so that when the clip is positioned on the stud to retain insulation previously impaled thereon, the clip is not inadvertantly disengageable from the stud.

Abstract: An insulated concrete wall having a centrally disposed layer of insulation and utilizing a unitary means for simultaneously maintaining form panels in a predetermined spaced relationship, and for maintaining the insulation in a predetermined spaced relationship between the form panels such that a permanent and reinforced mechanical connection is provided between said concrete walls and said interposed insulation.

Abstract: An arrangement is disclosed to secure a brake shoe in a caliper of a disc brake. This arrangement includes a lug of low minimum height formed in the center of the rear surface of the pad carrier plate in one single operation together with the manufacture of the pad carrier plate and a rectangular spring plate having a slot in the center thereof parallel to its long dimension to engage the lug in a locking manner with the opposite ends of the long dimension of the spring plate engaging a bearing surface in a central opening of the caliper in which the brake shoe is positioned.
