Abstract: A damping strut. An inner damping member is axially engaged with an outer housing. The outer housing is connectable to a tensioner arm. A wedge member connected to an immoveable mounting member is axially engaged with an inner portion of the inner damping member. The outer housing is axially moveable relative to the wedge member. A spring bears upon and urges the outer housing away from an end cap. The end cap comprises a rod, which extends axially within the wedge member and has an end connected to the inner damping member. The rod transmits a spring load force from the end cap to the inner damping member such that the inner damping member radially expands against the outer housing in response to the spring load force, thereby creating a frictional force between the inner damping member and the outer housing which damps an outer housing movement in proportion to the spring force.

Abstract: An apparatus for automatically assessing the quality of a printed circuit board assembly (6) using digitized video image analysis. The apparatus integrates with existing relatively low precision automated surface mount technology (“SMT”) manufacturing systems as an inspection station (56a) insertable at various steps in the assembly process or as a separate manually loaded station. The inspection station includes a high resolution video imaging system and a video image analyzer comprising an onboard master computer (26a) that generates control signals to reposition the camera mounted within a screen (45) on a movable carriage (22a) and/or reposition the circuit board, and adjust the lighting; and generates individual board status data to be archived, graphically displayed on monitors (40a, 41a) or otherwise utilized by a rework station.
Abstract: An encryption/decryption system for providing restricted use of each key in a plurality of keys to preserve confidentiality of the plurality of keys. Each key is usable by an associated user in a public key infrastructure to encrypt and decrypt data. The encryption/decryption system comprises a key storage means for storing a plurality of keys, user authentication means for determining whether a prospective user of a key in the plurality of keys is the associated user of the key, and an encryption/decryption means for encrypting and decrypting data using the plurality of keys when the user authentication means authenticates the prospective user. The encryption/decryption means is operable in a browser on a client computer.

Abstract: The invention comprises a cam die. The cam die comprises at least one cam ring. The cam ring comprises a plurality of moveable cam teeth. The cam teeth are moveable on a normal toward an axis of the cam die by a cam actuator. The cam actuator has an inside diameter that is less than an outside diameter of the cam ring. As the cam actuator moves parallel to the cam die axis along an outside circumference of the cam ring, the cam teeth are progressively engaged and pressed inwardly toward a work piece. The work piece is moved simultaneously with the cam actuator by action of a punch that is concentric with the cam actuator and within the diameter of the cam ring. Each cam tooth is simultaneously engaged with the work piece as the work piece passes. A resilient member returns each cam tooth to a starting position after the cam actuator is withdrawn, allowing ejection of a finished part.
Abstract: A collapsible trash bag stand having a sleeve-shaped body made from durable semi-rigid sheet material and having a plurality of punch-out, retainer tabs that snap into position to prevent the bag from slipping into the stand and to accommodate loading of multiple layers of trash bags at one time.
Abstract: The invention comprises a method of using tensioners to tune a belt drive system. A tensioner having a damping rate is used on an accessory belt slack side and a tensioner having a having a damping rate is used on an accessory belt tight side. Outside of a predetermined engine speed range, the tight side tensioner arm does not move because the dynamic tension in the span is less than the tight side tensioner friction damping. Within a predetermined engine speed range the tight side tensioner arm moves in order to damp a belt drive system vibration.
Abstract: A tension-regulated wire-feeding apparatus, particularly adapted to high speed winding of thin conductor wires upon an electronic component, applies a magnetic particle brake to the wire supply spool in inverse proportion to the pulling tension applied on the wire by the winding mechanism. The brake is controlled by an electric current generated by a controllable power supply. The output of the power supply is modulated by a follower potentiometer coupled to a lever arm which resiliently bear against a segment of wire unwound from the supply spool in order to monitor its pulling tension.

Abstract: A belt drive system and toothed idler sprocket having an arcuate pitch to significantly reduce noise. The toothed idler sprocket having a pitch sufficient to cause proper engagement between a belt and the sprocket at a minimal belt wrap angle.
Abstract: A method for centralized mass processing of substitutable, good-holding magazines used in conjunction with computer-controlled vending machines. A memory-chip-mounting smart-card is used, not only to enter into the machines the magazine location and price of the various goods, but also to carry a sales transaction record of the replaced magazine, thus avoiding the need for magazine locking mechanisms and other security measures.

Abstract: A process to fracture connecting rods and the like, that are made of high strength materials, comprises of the following mechanisms:
(a) Fatigue: fluctuation of stresses in a pre-notched connecting rod due to the use of harmonic excitation will extend the notch tip in the connecting rod and will weaken the predetermined fracture plane by creating micro-cracks,
(b) Resonance: resonance occurs when the frequency of the used harmonic excitation matches a natural frequency of the connecting rod, idealized as a structural system,
(c) Pre-stressing forces: by applying pre-stressing forces acting in the same loading mode, the stresses in the connecting rod due to several force components can be superimposed,
(d) Dynamic force: applying a dynamic force will raise the stress intensity factor, exceeding the fracture toughness of the material.

Abstract: A flexible drive ring CVT belt comprises a flexible drive ring having a plurality of adjacent ring segments. The segments comprise metallic or non-metallic material sufficient to bear a compressive load imposed by CVT sheaves. The segments are interlocked along a longitudinal axis and are preloaded in the assembled position by an elastomeric member. A tensile member or belt bears on an outer circumferential bearing surface formed by the interlocked segments. The tensile member is moveable along a longitudinal axis relative to the flexible drive ring on the circumferential bearing surface. The segments further comprise opposing inclined surfaces for engaging sheave surfaces on a pulley.
Abstract: A power transmission belt is disclosed in which the exterior of the overcord section is generally flat in contour and bears an outer seamless tubular knit textile material adhered to an adjacent rubber layer material interposed between the exterior belt back surface and a strain-resisting tensile section. The belt is adapted to be run against backside idlers or tensioners with minimized noise generation. A simplified process including use of a tubular knit stretched over and applied to the building drum is disclosed, thereby eliminating conventional calendaring and Bannering operations.
