Abstract:
An asymmetrical-force connector system includes a socket having a longitudinally-oriented shaft bore defining a bore axis. A spring-receiving cavity is coaxial with the bore axis and extends laterally around the shaft bore. The spring-receiving cavity has an inner circumference that is open to the shaft bore. A toroidal canted coil spring is located at least partially within the spring-receiving cavity. The toroidal canted coil spring has an inner spring circumference. A connector pin including a maximum shaft circumference is configured for selective sliding insertion into the shaft bore longitudinally from the front housing face. A v-groove extends laterally inward from the maximum shaft circumference toward the pin axis and defines a minimum shaft circumference. The connector pin is located in a maintenance position within the shaft bore when at least a portion of the toroidal canted coil spring laterally extends into the v-groove beyond the maximum shaft circumference.
Abstract:
The invention concerns a device for the suspension of a payload in a space launch comprising annular chambers of fluid with variable geometry (12i) installed between said launch and said payload and first (10") and second (11") rigid members fixed, on either side of said chambers (12i), to said payload and to the launch respectively so as to transmit the stresses between the latter through said chambers. The fluid chambers (12i) and the first (10") and second (11") rigid coupling members are coextensive, ring-shaped and coaxial with a longitudinal axis common to the launch and to the payload. The first (10") and second (11") annular rigid coupling members each comprise external (10a", 10b") and internal (11a", 11b") ribs respectively, axially separated by one of the annular fluid chamber (12i).

Abstract:
For load compensation, different kinds of elastomeric load compensators are placed at various locations on the crane for increased flexibility and for shock and vibration absorption. The elastomeric load compensators employ elastomeric tension elements, elastomeric torsion elements, or elastomeric shear elements. Elastomeric tension elements can be simply inserted in series with the main hoist rope. An elastomeric load compensator employing elastomeric torsion elements is mounted to the underside of the boom for receiving the live end of the main hoist rope. A single stack of elastomeric shear elements is suitable for mounting a hoist or winch or an idler sheave to the crane structure. For additional load compensation, the hoist, winch, and idler sheaves are mounted on rails for increased displacements under heave loads, and the increased displacements are compensated by elongated elastomeric tension elements or multiple elastomeric tension, torsion or shear elements in series.
Abstract:
To provide a power tool (1) capable of reducing an initial load applied to a spring in an initial state, and absorbing effectively a vibration in a low vibration range. An energizing apparatus is a neidhart spring that consists of a cylindrical outer frame portion (131) whose outer shape is a substantially square column shape and which is fixed to a gear housing (30), four circular rubber rods (132) arranged on the inner peripheral side of the outer frame portion, and a square column portion (133). The square column portion is arranged such that its four corners are positioned between the rubber rod and the rubber rod respectively and its longitudinal direction coincides with the longitudinal direction of the rubber rods. A bolt (116) that can be turned together with a left portion of a sub handle (110) is passed through an axial position of the square column portion, and the bolt and the square column portion can be rotated together.
Abstract:
A geometric shaped side bearing pad (10) includes a top (22) and a surface extending an angle (theta) towards the top, wherein the bearing pad has a geometric shape and a non-linear spring rate which levels out a reaction force without buckling. The surface of the bearing pad can have two sides or four sides, can have spacing within the surface, or can be solid. The angle (theta) can be within the range of about 20 degrees and 85 degrees, and may preferably be within the range of about 30 degrees and 45 degrees to achieve non-linear load/deflection. The top of the bearing pad can have a slot (30) defined therethrough to accommodate a protrusion in a fixture to engage the bearing pad. The bearing pad can provide a friction contact with an object and enables lateral force transfer to the bearing pad, thereby providing lateral stiffness.
Abstract:
The invention relates to a hand prosthesis comprising a chassis (1) and coupling elements (2) for fastening the hand prosthesis to an arm stump, and also comprising a joint for flexing and extending the hand prosthesis in relation to the coupling elements (2), the chassis (1) being maintained in a neutral position against a spring bias. The invention is characterized in that at least one spring element (3) is associated with the chassis (1) and has a progressive spring characteristic and provides an increasing counterforce with increasing flexion and extension angle.
Abstract:
Ein elastisches Lager, insbesondere zum Abstützen eines Getriebes oder des Motors eines Kraftfahrzeugs, ist mit einer Tragfeder (10) versehen. Die Tragfeder (10) weist zwei keilförmig angeordnete Schenkel (11, 12) und einen mit einem Stützarm (40) verbindbaren Lagerkern (13) auf. Zudem ist das elastische Lager mit einer Grundplatte (20), auf der die Schenkel (11, 12) angeordnet sind, und einem Gehäuse (30), das die Tragfeder (10) umgibt, versehen. Die Tragfeder (10) ist im Bereich des Lagerkerns (13) mit wenigstens einem Vorsprung (14, 15) versehen, wobei das Gehäuse (30) eine dem Vorsprung (14, 15) gegenüberliegende Anschlagfläche (31, 32, 33, 34) bildet. Das elastische Lager zeichnet sich bei kostengünstiger Fertigung durch ein vergleichsweise einfaches Einstellen des Dämpfungsverhaltens aus. Grund hierfür ist, dass die Schenkel der Tragfeder (10) an jeweils einer zugeordneten Stützfläche (21, 22) abgestützt sind, die in die Grundplatte (20) eingeformt und angewinkelt zu der Grundplatte (20) ausgerichtet ist.
