Abstract:
A linerless label applicator for forming and applying a discrete, pressure sensitive adhesive linerless label to a document is adapted to receive and advance a plurality of documents, one at a time, along a document path through the applicator. The applicator includes a label storage and feed section, a label cutting section and a label application section. The storage and feed section stores the label material in roll form thereon and feeds the material through a feed assembly into the cutting section. The label cutting section includes a label drive assembly, a label guide assembly and a cutting assembly. The drive assembly includes a feed roller and a plasma coated idler roller which contacts the label adhesive and prevents adhesion thereto. The guide assembly includes a fan/vacuum manifold which retains the non-adhesive side of the label material in contact with the cutting assembly surfaces. The cutting assembly includes self-lubricating stationary and moveable blades adapted to coact with one another to cut the label material into predetermined, discrete labels.
An improved low-cost circuit breaker mechanism is provided which dispenses with the complicated and costly conventional use of latch mechanisms for realizing the tripping action. The circuit breaker mechanism essentially comprises an input electrical terminal having an associated contact where current is received, an output electrical terminal where current is delivered out of the breaker, and a conductive deformable section cantilever blade formed of thermostat metal and adapted to establish a conductive current path between the input contact and the output terminal. The cantilever blade is disposed in a normally closed position with a first end affixed to the output terminal and a second free end contacting the input contact, and is adapted to deflect from its normal closed position to an open position for interrupting current flow when the temperature of the cantilever blade increases as a result of the monitored current exceeding a threshold value. The circuit breaker mechanism is provided with means for exerting a mechanical force for stimulating the cantilever blade, after it has been deflected by an over-current condition, back to its normal closed position. A remote control arrangement is also provided which permits remote activation of the circuit breaker mechanism by effectuating the force required to effectively deflect the cantilever blade by exertion of appropriate electromagnetic fields on an armature element linked to the blade.
A constant velocity universal joint for transmission of torque between driving and driven shafts, wherein a drum member is secured to one of the shafts on which are mounted at least three trunnions each having a ball member slidably and rotationally mounted thereon. Ball members have a generally spherical outer surface and the other shaft has a grooved member thereon having at least three cooperating grooves receiving the ball members. The trunnions extend inwardly from the drum member and are connected together at the inner end thereof.
A gear rattle detector is adapted for use with a gear set having meshing drive and driven gears. The gear rattle detector comprises a magnetic pick-up including a base, a first arm extending from the base and defining a north magnetic pole, a second arm extending from the base and defining a south magnetic pole, and a coil wound around the base. The poles are spaced sufficiently such that they span the root circles of the gears.

International Classification:
F16H 5556
US Classification:
474 8
Abstract:
An apparatus and a method for generating same provides a pulley sheave inner face profile for a variable pulley of a continuously variable transmission allowing the crowned face chain-belt centerline to remain in a plane substantially perpendicular to the axis of the pulleys at all times and at all drive ratios. Given a primary pulley sheave inner face profile, a corresponding secondary pulley sheave inner face profile can be developed to achieve substantially perfect belt alignment. The pulley sheave inner face profiles may be designed to be identical or congruent. Congruent pulley sheave inner face profiles can be developed according to an algebraic solution allowing numerically controlled design and manufacturing techniques in the fabrication of the sheave inner faces.
A constant velocity universal joint for the transmission of torque between driving and driven shafts having a member secured to one of the shafts on which are mounted a plurality of trunnions each having a partial ball member slidably and rotationally mounted thereon. The ball members have a generally spherical outer surface and the other shaft has a member thereon having at least three cooperating grooves therein which receive the ball members. A torque transmitting member is connected to the one shaft and to the outer end of the trunnions whereby torque is transmitted through the outer end of the trunnions as well as at the connection of the trunnions to provide for parallel torque paths into the trunnions to prevent distortion and failure thereof during operation.
A torsional coupling or resilient damper assembly for a friction clutch or torque converter lock-up clutch which is formed of a plurality of spiral spring plates or discs that are secured together as a unit with an outer peripheral ring and an inner ring for each disc joined together by one or more spiral spring members formed by one or more spiral slots extending between the inner and outer rings. The coupling is formed of a stack of plates wherein the slots in the plates are axially aligned and the forces in the plates are balanced when two or more spiral slots are utilized. If a single spiral slot is provided in each disc, the forces are balanced by alternate plates being reversed or all plates being positioned identically but phased through angles divisible into 360. degree. Different embodiments of spiral spring discs may be combined in a single assembly.
