Abstract: Disclosed herein is a foldable truss support structure adapted for commercial displays. The truss structure includes a pair of wall members with elongated pivot members rotatably connected therebetween by internal hinges. The pivot members are foldable inwardly to allow the truss to fold into a compact form. In an alternative embodiment, a second pair of wall members are rotatably coupled to the first pair of wall members. A pair of outer hinges couples the wall members at one pair of diagonal corners and a pair of inner hinges couples the wall members at the other pair of diagonal corners. The truss members can be folded into a compact orientation for storage and shipping.

The arm members are pivotally connected at each end to an adjacent arm member to form a closed loop. The end cap includes an attachment member disposed at each pivotable connection. A plurality of substantially planar wall members are coupled to the attachment members of the end cap by receiving a portion of the end cap in a receiving opening of the wall members. A pair of pivot bars are connectable to diagonally opposite pivot locations of the end cap to stabilize the truss assembly. The pivot bars include a locking member connectable to the free ends of the pivot bars. The locking member prevents relative longitudinal displacement of the pivot bars and prevents the end caps from folding to stabilize and strengthen the truss assembly.

Abstract: An interlock unit (10) for use with at least one other like unit (11) to form an interlock mechanism has a top face (13) and opposed pairs of side walls (12) with at least one runner bar (17, 18) mounted in the unit for lateral sliding movement. An actuator (14, 15, 22) is supported on the top face (13), to effect lateral sliding movement of the runner bar (17, 18). One wall of the unit is provided with one part (27) of a two-part connector with the other part (33) on the opposed wall whereby two similar units may be joined together by relative sliding movement of the two units in the plane of the side walls (12). Joining together of two units (10, 11) in this way also joins together the runner bars (17) or (18) of the two units such that sliding motion of the runner bar (17) of one unit (10) is transferred to the runner bar (17) of the connected unit (11), for at least one direction of sliding movement of the runner bars (17).

Abstract: A foldable truss member suitable for commercial displays includes a plurality of side members that are hingedly connected together. The side members include support members and bridging members having extensions. The side members are joined into a foldable structure with a hinge member between the support member and extensions of adjacent side members. The truss includes frictional hinge surfaces that hold the truss member in a deployed configuration. A display structure can be formed by connecting a locking frame between two truss members.

Abstract: A system, device, and method for determining whether an individual has consumed, is intoxicated, or is otherwise impaired by alcohol is disclosed. Further, a device capable of positively identifying the person who provides the impairment test is disclosed. The impairment detection and interlock system disclosed accomplishes this with the use of a video camera that selectively saves images, and an attitude evaluator and, in some embodiments, an exposure evaluator, which ensures that the video camera captures the identity of the tester. A device holster may also be used to facilitate video surveillance.

Abstract: A foldable truss member suitable for commercial displays includes a plurality of side members that are adjacently hinged together. The side members include support members and bridging members having extensions. The side members are joined into a foldable structure with a hinge member between the support member and extensions of adjacent side members. The truss includes a locking frame that is removably attached to ends of the side members. A display structure can be formed by connecting a locking frame between two truss members.

Abstract: A fastener connects an insert to a hollow tube. The fastener is formed to have a yoke portion extending between a pair of arm portions, all of which are formed arcuately to conform to the shape of tube. Arm portions have arcuate free ends with horizontally oriented seams. Arm portions include protuberances which then may be cammed between an engagement position with edges of openings in the tube and edges of a cavity space in insert and a disengageable position between the edges. The fastener includes a lifting handle that is spaced away from the tubes surface to form an access gap.

Abstract: A fastener for a closure. The fastener has a friction joint which couples first (10) and second (23) elements such that rotational movement there between can occur. The friction joint has a head fastener (28) and a sleeve (24) to which an end load is applied upon axial movement of the fastening taking place during coupling of the first and second elements (10, 23). This end load causes the sleeve (24) to collapse. The fastener has a wedge element (37) mounted for rectilinear movement in a direction substantially transversed to the axis of rotational movement of the friction joint. A drive arrangement (35) couples the wedge element (37) with the second element (23) such that rotation of the second element (23) is translated into the rectilinear movement of the wedge element (37). A removable handle (44) couples via fingers (49) to second element (23).

Abstract: A dry wall building system comprises courses of building blocks where the building blocks are joined end to end by keys. Each of the blocks comprising sidewalls, endwalls and at least one vertical cavity or slot, at least one first channel in the upper surfaces of the endwalls and at least one second channel in the lower surfaces of the endwalls, the arrangement and construction being such that when blocks are laid one upon another the channels and the said at least one cavity or slot of the blocks can be aligned to provide an internal network of horizontal and vertical infill passages which can be filled with a settable material to seal joints between the blocks and to provide load bearing support between respective courses of blocks. A method of manufacturing blocks is also disclosed.

Abstract: A filter electrical connector having a housing and a contact and filtering circuit subassembly. The contact and filtering circuit subassembly has a ferrite block, electrical contacts passing through the ferrite block, and a lead frame and circuit element assembly. The lead frame and circuit element assembly is mounted on the ferrite block and is electrically connected to the electrical contacts.

Abstract: A folding handle for attachment to a rotatable shaft element. The handle includes a handle body 10 having a cavity 17 within which a mounting block 20 is engaged. The mounting block 20 has oppositely projecting pivot members 21 slidingly engaged in recesses 19 in the walls 18 of the cavity 17. The pivot members 21 therefore engage with bearing surfaces 19a to facilitate pivotal movement of the handle body 10 relative to the mounting block 20. A clip 24 retains the mounting block 20 in cavity 17. No pivot pin is therefore visible.

Abstract: A window fastener having a mounting base (21), a latching flap (12) moveably coupled thereto, a handle (14) and a latching tongue (15). the handle (14) is movable between first and second positions and is coupled to the latching tongue (15) so that the latching tongue moves the latching flap (18) when the handle (14) moves to a latching position. A movement inducing mechanism (34, 41) operable by the handle (14) causes movement of the flap (12) to occur when the handle is moved from the latching position to a non-latching position.
