Abstract: A helical jumper connector includes a helical support member configured to support a wire. The helical support member includes a first leg having a first helical winding and a second leg having a second helical winding that defines a second axial opening. The first axial opening and the second axial opening are coaxial with the wire when the first helical winding and the second helical winding are wrapped around the wire and cooperatively engage with one another to support the wire. A jumper casting is configured to receive the helical support member. The helical support member and the jumper casting are electrically conductive such that the helical jumper connector forms an electrically conductive pathway to carry electrical current from the wire. A method of making a helical jumper connector assembly includes applying a compression force to a helical jumper connector comprising a helical support member received in a jumper casting.

Abstract: A clamp system for attaching accessory devices to a railing structure includes a first clamping jaw member and a second clamping jaw member designed to clamp on a railing structure. An accessory mounting device includes a cylindrical collar portion with a plurality of diametrically aligned holes arranged around the circumference. One of the clamping jaw members has an opening, sized to receive the collar portion and one pair of holes that can be aligned with the holes of the collar portion.

Abstract: A latch apparatus and attachment system for a docking station, with improved ease of closure and a connection lock capability, includes multiple connected latch members; a first of which is connected to a moveable base portion of the docking station; a second of which is substantially curved to form a mechanical moment; and a third of which is connected to a lever separate from the base portion. The multiple member latch apparatus and attachment system decreases an initial rest angle between the first member and the base portion of the docking station, which reduces lateral friction forces as the base portion of the docking station moves laterally. The curved member of the latch apparatus and attachment system improves efficiency of operation via the mechanical moment which decreases an amount of necessary force applied to the lever to accomplish a given amount of work.

Abstract: In an apparatus known as a wire bonder, a new type of one-piece joint element (20) is used as the articulated link (G) between a support unit (pivoting rocker 30) and a bonding unit (10) that carries a capillary (12). One or more such joint elements (20) define a virtual pivot axis (A2) for the unit (10), which lies outside the unit and thus provides a passage in the apparatus wide enough for relatively wide workpieces (chips 1 on substrate 2). A joint element (20a) is made in one piece and has at least two elastically flexible blades (22a) converging toward each other relative to a symmetry plane (S), and the blades are connected to each other by two rigid sections (23a, 24a). One of the rigid sections (23a) is attached to (and removable from) the support unit (30), the other (24a) is attached to (and removable from) the bonding unit (10), so that the joint element (20) is easy to fit or exchange.

Abstract: A deployable structure that synchronously deploys in both length and width is disclosed which is suitable for use as a structural component for orbiting space stations or large satellites. The structure is designed with maximum packing efficiency so that large structures may be collapsed and transported in the cargo bay of the Space Shuttle. The synchronous deployment feature allows the structure to be easily deployed in space without a complex deployment mechanism. The structure is made up of interconnected structural units, each generally in the shape of a parallelepiped. The structural units are constructed of structural members connected with hinged and fixed connections at connection nodes in each corner of the parallelepiped. Diagonal members along each face of the parallelepiped provide structural rigidity and are equipped with mid-length, self-locking hinges to allow the structure to collapse.

The hand truck apparatus in accordance with the invention provides mechanical advantage for lifting the load and is configured for precisely lifting the load to a raised position. The hand truck apparatus in accordance with the invention is self-stabilizing when a load is not placed on the hand truck apparatus, as well as when a load is placed on the hand truck apparatus and for any raised position of the load. The hand truck apparatus in accordance with the invention is particularly advantageous when used in connection with transporting and installing solid core doors. Hinge plates are first attached to the edge of the door. The door is then placed on the hand truck apparatus and transported to the location of installation.

Abstract: A fastening system particularly suited for securing parts of a rotor of a slant axis rotary mechanism together including links (110) abutting each of the rotor parts (60, 62), and spanning the interface (ABCD) between the parts. Pivotal nut structures (108) are journalled in the ends of the links and linear passageways (90) are disposed in the rotor parts to be nominally aligned with the nut structures. The passageways are at an acute angle to the rotor axis and terminate in a shoulder (100) at their ends remote from the nut structures. Threaded, headed fasteners have their heads (98) in operative engagement with corresponding ones of the shoulders and extend through the passageways to be threadably received by the corresponding nut structures to tension the associated links and thereby hold the rotor parts in assembled relation.
