Abstract:
Die Vorrichtung zur Befestigung einer Montageschiene (20) an einem Gewindeschaft (30) umfasst ein Halteelement (1), ein Klemmelement (2) und zwei Muttern (3, 4). Das Halteelement (1) weist eine Auflagefläche (7) für eine Auflageseite (21) der Montageschiene (20) auf sowie außerdem einen Greiffortsatz (8), der bezüglich der Auflagefläche (7) abragt und zum Hintergreifen eines Halterandes (22) der Montageschiene (20) ausgeführt ist. Der Gewindeschaft (30) durchdringt das Halteelement (1) in einem ersten Langloch (5) und das Klemmelement (2) in einem zweiten Langloch (6). Beide Langlöcher (5, 6) sind quer zur Montageschiene (20) gerichtet. Das Halteelement (1) und das Klemmelement (2) sind axial zwischen den beiden mit dem Gewindeschaft (30) im Eingriff stehende Muttern (3, 4) angeordnet und mittels dieser an verschiedenen Positionen entlang des Gewindeschafts (30) zusammenspannbar. Ein Zusammenspannen bewirkt eine Annäherung des Klemmelements (2) und der Montageschiene (20). Hierzu weist das Halteelement (1) mehrere nacheinander angeordnete Spannschrägen (9a.. 9d) auf, die mit zunehmendem Abstand zur Montageschiene (20) einheitlich ansteigen und auf denen das Klemmelement (2) mittels korrespondierende Gegenschrägen (10a.. 10d) abwärts gleiten kann. Bei zueinander verspannten Muttern (3, 4) ist die Montageschiene (20) vom Klemmelement (2) gegen den Greiffortsatz (8) geklemmt und vom Greiffortsatz (8) auf der Auflagefläche (7) niedergehalten ist.

Abstract:
A two-sided joint for splicing two laminated wires together, while preserving the mechanical integrity of the wire is disclosed. The two-sided joint can splice two laminated HTS wires having tapered ends and includes a bottom strap and a top strap. Under one aspect, a laminated, spliced superconductor wire includes a superconductor joint, which includes first and second superconductor wires, each wire including a laminate layer, a substrate layer overlaying the laminate layer, a buffer layer overlaying the substrate layer, a superconductor layer overlaying the buffer layer, a gap layer overlaying the superconductor layer, and a laminate layer overlaying the gap layer, a first HTS strap in electrical connection with the second laminate layer of the first laminate wire and the second laminate layer of the second laminate wire, and a backing strap proximate to the first laminate layer.
Abstract:
A support structure flange preform (11) resembles the Greek letter "pi" and has a base (13) with two legs (15, 17) extending therefrom. The perform is composed of a composite material that is formed from tows of woven or braided fiber. The tows are oriented to extend throughout each the base and legs. The perform may be either impregnated with a suitable thermoset resin, or may be unimpregnated so that resin may be infused at a later step of the overall manufacturing process. Two of the preforms are joined to a sine wave-shaped web (31) of the structural beam. The web is formed from uncured, thermoset resin sheets that are reinforced with oriented fibers. The web has two outer laminates that sandwich a syntactic or foamed resin layer in between. The legs of each perform straddle one edge of the web and are shaped to both sides to the precise contours of the web. A laminate strip (33) is positioned against the base of each preform to create a pair of flanges for the structural support member. The assembled structure is then heated and cured. The web and/or flanges of the structure also may be configured with alternating beads, tapered in either the vertical or horizontal direction, or inclined at non-orthogonal angles.
Abstract:
Processes are disclosed for producing plastic containers from thermoplastic sheets were the thermoplastic sheets are processed in parallel to form a low permeation plastic container. A plurality of thermoplastic sheets (50) are progressively heated to a first temperature in a pre-conditioning stage (14). A group of the thermoplastic sheets (56) are selected from the plurality of thermoplastic sheets (50) and rapidly heated to a second temperature in a final heat stage (16). The group of thermoplastic sheets (56) are then processed in a forming stage (18) to form the low permeation plastic container.
Abstract:
Forms for display of clothing and the like with magnetically attachable parts are provided. The magnetic joints (14) comprise a magnetic assembly with a depth of pull sufficient to cause the attachable part to begin to pull toward the form at a distance preferably greater than one-half inch, preferably about one inch. Preferably the magnetic assembly has a depth of pull of at least about 120 gauss at a distance of one inch. A metallic plate is arranged in mating configuration with the magnetic assembly. Mating pins (18) may be provided, as well as indexing pins (16). If the manikin is knocked over, or if the attached part is pulled or bumped, it will come loose rather than breaking off; and the mating parts are self-seeking in use, so that they will come together in proper orientation even when being mated beneath clothes. A bump to the manikin sufficient to overcome the on-contact strength of the magnetic attachment may not result in detachment of the limb because of the depth of the pull strength of the magnetic assembly. The indexing pins allow the limbs to be placed in a variety of positions.
Abstract:
A monocoque joint (30) for joining panels having a first skin portion (32) having a first exterior surface and a first interior surface, a second skin portion (34) having a second exterior surface and a second interior surface, a plurality of web sections (40, 41, 42, 43), each of the web sections being in communication with the first interior surface and the second interior surface, the web sections and the first and second interior surfaces defining a plurality of core regions (44, 45, 46), and first and second tapered flange sections (48, 49) disposed on opposing ends of the joint. The first and second flange sections (48, 49) are formed integrally with the first and second skin portions and are adapted to receive preformed panels (50, 52). The joint (30) provides a substantially continuous integral load path whereby when the first and second flange sections are operatively attached to preformed panels and subjected to a load, the load is substantially uniformly transmitted to the panels.
Abstract:
An end of a composite cylinder (40) is formed about an end connection assembly having two longitudinally arranged pieces (42a, 42b) having a contour which prevents the withdrawal of the end connection assembly from the cylinder. The two pieces of the end connection assembly are relatively forced apart and a snap ring (46) having a certain rest diameter is reduced in diameter and inserted into the end connection assembly to a position between the pieces. The snap ring then assumes its rest diameter positioned between the pieces, forcing them to maintain intimate contact with the inner surface of the cylinder, thus removing any residual gap from the assembly process and/or preloading the interface between the end of the composite cylinder and the end assembly prior to application of an axial load.
Abstract:
A joined metallic work produced, in general, by metallurgically joining a shaped member of nickel-titanium alloy and another shaped member of nickel-base alloy while forming a forging texture between the two members. The production process comprises momentarily heating the joining sites of the two members in an inert atmosphere and pressing these sites in a thermally softened state against each other at a high pressure to form a forging texture therebetween.
