A duty distortion detector comprises a first synchronous mirror delay configured to mirror a first signal with respect to a clock signal to provide a second signal, and a second synchronous mirror delay configured to mirror the second signal with respect to an inverted clock signal to provide the first signal.

A method for mounting a light duty bearing having a groove defined in an outer arcuate surface thereof for receiving a metallic tolerance ring placed therein which includes protruding waves extending radially outwardly from the groove while the main band of the bearing is positioned preferably completely within the groove such that the bearing can be placed into a workpiece aperture to be movably mounted therein in a frictionally resisted manner such as required in light-duty applications where ...

A duty cycle correction circuit comprises an averaging circuit configured to receive a first signal and a second signal and provide a third signal, a duty restoration circuit configured to receive the third signal and a fourth signal and provide a fifth signal having a duty cycle closer to 50% than the first signal, and a synchronous mirror delay circuit configured to receive the fifth signal and provide the second signal.

A magazine loader comprises a magazine compartment (30), an elongated slideway (14) having a bullet and a case grooves (18, 22), respectively, along its length profiled to receive and retain the distal ends of rounds (50) between them, and a slider (40) slidable in slideway (14). A magazine (60) is positioned in compartment (30) such that its open end is perpendicular and in continuation to slide-way (14), and is leveled to receive rounds (50) slidable in slideway (14). Slider (40) is moved away...

The top wall of an article carrier is provided with a pair of hand gripping apertures and a number of score lines are arranged to extend from adjacent an end of a hand gripping aperture outwardly in a diverging path toward the corners of the top wall. By this means the top wall of the carrier is rendered especially strong by efficiently distributing the weight of the carrier and its contents so that the caliber of board used may be substantially reduced and economies thereby effected.

A tube coupling with only a body and a threaded member is disclosed, the threaded member usually being a nut to overlie an outer sleeve and an inner sleeve unitary with the body. These two sleeves define therebetween an annular groove to receive the end of the tube. The method of tightening the nut onto the body provides that a generally conical cam surface on the nut interacts with a shallower taper conical cam follower surface on the outer sleeve to force this cam follower surface radially inw...

A heavy duty cast iron yoke (110) has two lugs (116) for receiving a journal cross and a spline body or barrel (112) defining an internal spline (114). A lug tie-in body (124) includes shoulders (128) which join the lugs (116) to the spline body (112). The internal radius (136) of the shoulders is at least 20% of the distance (134) between the internal surfaces of the lugs. An annular 15.degree. ramp (150) is provided intermediate the outer spline body surface and the lugs.

Circumferentially spaced, radially movable die members for crimping are mounted in a die supporting ring positioned radially inward of circumferentially spaced radially movable pusher members engageable with the die. The die supporting ring is removably mounted on a fixed head and the pusher members are urged radially inward by axial movement of a crimping head having sloping surfaces slidably engageable with sloping surfaces of the pusher members. The slidable sloping surfaces of the crimping h...

The weigh scale incorporates a weighbridge, load cells and load cell mounting mechanisms for each load cell. The load cells are double ended shear beam type horizontally mounted directly under the main beams of the weighbridge with the ends of the load cells being rigidly secured to a load cell stand which in turn is supported upon the concrete base of the weigh scale location. The load is vertically applied to the load cell by means of a chair for each load cell and a link plate. Each of the si...

A pump jack arrangement for traveling up and down a pole including a frame member upper and lower shackle members supported by the frame member. A pump arm and a support arm are provided for supporting weights. The pump arm is utilized for causing the shackle members to alternately grip the pole. The non-gripping shackle member is stepped upwardly along the pole. The upper and lower shackles include pivotally interconnected yoke members and linkage members which are pivotally connected utilizing...
