Abstract: A belt de-installation tool having a monolithic curvilinear body. The body comprises a pulley engaging surface for engaging a perimeter of a pulley. A sloped arcuate belt engaging surface extends from the pulley engaging surface at a predetermined angle. A curved surface also extends from each end of the tool at a predetermined angle to the belt engaging surface. The tool is placed on a pulley between belt spans. As the pulley is turned the belt rides up on a curved surface of the tool, holding the tool in contact with the pulley. As it rotates, the belt comes into engagement with and gradually tracks across the sloped arcuate belt engaging surface, moving laterally to a pulley plane until it is fully disengaged from the pulley groove by action of the sloped arcuate belt engaging surface.

Abstract: The invention comprises a tensioner that is particularly useful in micro-V front end accessory belt drive systems used in automotive applications where minimum tensioner bulk combined with maximum balancing and minimum pivot bushing wear in order to achieve maximum pulley alignment over the expected life of the tensioner. The belt tensioner of the invention is of the type with a base. A pivot-arm is attached to a cylindrical member that supports the pivot-arm and rotates about a pivot secured to the base. At least one sleeve-type bushing is positioned on the pivot and includes a bearing surface that supports the cylindrical member. A pulley is attached to the pivot-arm for engaging the belt and receives a belt load that generates a belt force component that is transmitted to the cylindrical member (hub load) A torsion spring having one end connected to the base and another end interconnected to a damping means generates a damping force component acting in the opposite direction as the belt force component.

Each device is positioned at a common point of adjacency of a plurality of slabs. Each device has a rotatively mounted locking plate for engaging slots in the sides of each of the slabs. The plate has a cutaway sized and dimensioned to allow for the passage of one of the slabs through the cutaway when the cutaway is rotated into proper alignment. A keyed tool may be used for turning the plate indicating the positioning of the cutaway. The plate is mounted to allow minor axial, pitch and yaw movement and is biased toward an axially perpendicular orientation.

Abstract: An assembly device for a shaft damper. The assembly device comprises a holding member for holding a damper. The holding member is releasably engaged with a pair of parallel elongate members. An actuator is connected to the elongate members and to a piston. A shaft damper is inserted into and temporarily held by the holding member. The holding member containing the shaft damper is inserted into a shaft a predetermined distance. The actuator then slidingly retracts the holding member while a pressing member at an end of the piston simultaneously holds the damper in the proper position in the shaft.

Abstract: The invention comprises a geared drive ring coupler. The geared drive ring coupler comprises two pairs of adjacent drive rings rotatably connected to each end of a frame. Each pair of drive rings is meshed together with the cooperating pair of drive rings on the opposing end of the frame. The relative spatial arrangement of the axis of rotation of each set of drive rings is maintained by the frame, which in turn holds the drive rings in a predetermined relationship between the pulley sheaves. The drive rings on the driver pulley turn in the same direction as the driver pulley through frictional contact with the sides of the CVT driver pulley sheaves. The drive rings on the driven pulley side rotate in the opposite direction to the drive rings on the driver pulley, since they are meshed together. The driven drive rings are then in frictional contact with the sides of the driven pulley sheaves, thereby driving the driven pulley.

Abstract: An idler having a flexible member. The flexible member comprises a rubber or elastomeric material. The flexible member also defines a gas chamber. The spring rate of the flexible member is a function of the flexible material and the size of and pressure in the gas chamber. A belt or chain bearing surface of the flexible member bears upon a belt or chain trained between two pulleys. The flexible member is compressible in response to a preload caused as the idler is pressed against the chain or belt. The flexible member damps vibrations in the belt or chain during operation. This results in quieter operation of the idler/pulley system as well as increases the operating life of the belt.

Abstract: The invention comprises a belt installation tool for installing a belt on a pulley. The tool comprises a plurality of segments. The segments and the headpiece are connected by a flexible connector with a headpiece attached to one end of the string of segments. Each segment comprises a belt bearing surface and a lip for engaging a pulley rim, thereby conforming to the curve of the pulley rim. The belt bearing surface describes a tapered surface. A surface normal to the belt bearing surface on each segment urges a belt from the tool onto a pulley as the pulley is turned.

Abstract: Apparatus for extruding an elongated article comprising a die having an opening therethrough; an extruder for discharging extrudable material through said die opening; structure for rotational movement between said die and said extruder so as to provide said elongated article having a rotational profile.

Abstract: The invention comprises a method of forming a sheet metal cup without using a mandrel. A cup shaped blank is first produced having a relief on a rim or outer circumference. The blank is clamped in the spinning machine. The relief controls and facilitates the bending process, creating a uniform curve at a predetermined bending point. During the rolling process, a forming roller is engaged with rim, and is moved progressively parallel with an axis of rotation. As the forming roller moves, the rim is progressively bent from an orientation normal to an axis of rotation to a position parallel to the axis of rotation. The fully formed rim can then be punched to accommodate a bearing or shaft. This allows a small radius pulley to be formed without use of a mandrel.

Abstract: A self-erecting structure includes a series of fabric panels each tautly spread by a length of steel wire or other resiliently flexible, filiform material. The steel wire may form a closed loop, an open loop or a mere arc. The wire is selectively inserted into at least two of several pockets or fabric straps positioned around the periphery of the panel. The selection of the wire-holding pockets or straps defines the shape of the spread-out panel. Parts of the fabric which are not encompassed by a wire are held folded over it and against the spread-out portion. The shape of the structure can be quickly modified by repositioning of the wires.

Each slot having a complex radius between a central pillar and an upper arm and lower arm in order to avoid stress risers. Each load carrier is slightly compressed in each slot to reduce block skew.

Abstract: A multi-channel digital equivalent time sampling (MDETS) device having a programmable logic control that can select, delay or create various triggered signals. The MDETS can function independently or with multiple devices allowing for synchronized acquisition of data. The close proximity of MDETS device to a transmitter and receiver allows for the short time delay for acquiring the data.

Abstract: The invention comprises a cog type belt having a plurality of transverse teeth on an inner surface. The belt comprises an outer extensible elastomeric layer, an inner compression layer and a tensile member. Each tooth further comprises a non-metallic or plastic transverse member, pillar or rod that extends across the width of each tooth. The opposing outer surfaces of each transverse member are inclined to each other and each end approximately equates to an outer surface of the belt body elastomeric. A compressive load between the sheaves is carried by the rod and the sidewall in proportion to the modulus of each component. The transverse members have pegs or legs that allow proper spatial orientation of each transverse member in each tooth during the fabrication process, thus assuring proper operating characteristics, including proper alignment within a pulley.
