Abstract: A novel through-hole interconnect for connecting a power plane conductor to a through-hole includes a central pad connected to the through-hole and a deformable hinge that connects the central pad with the power plane conductor in a multilayer circuit board. The central pad and hinge are defined by a non-continuous area removed from the plane conductor. Preferably this area has a C-shape. During the compression process to join the core assemblies, deformation of the hinge advantageously absorbs the shear forces and allows the power plane beyond the hinge to remain substantially planar. The resulting multilayer laminated circuit board includes a plurality of cores laminated together in a stacked configuration and a plurality of plated through-holes defined in said multilayer laminated circuit board each of which is connected to a plane conductor by a hinge deformed so that the interconnect area is aligned outside of a plane defined by the plane conductor.

Abstract: A swing having a stationary support member to which is pivotally attached to first and second arms. The first and second arms are in turn pivotally attached by connectors on side wings that extend from a base member. The base member has an arcuate surface that extends from a first end to a second end with the side wings extending on a tangent from the second end for a fixed distance to a terminus point. The center of gravity of the attached base member is selected such that the base member is in an approximate horizontal plane with the first and second arms in a rest position. A person mounts the base member to define a prone position with their hands on a handle adjacent the first end and feet located on a support attached to the terminus point of the side wings. As the person propels the base member in an arc about a first pivot of the first and second arms and stationary support, the base member pivots rotates in a counter manner on yokes which attached the side wings.

Abstract: In a dynamoelectric machine, a fan diffuser and collector combination is part of the cooling system of the machine. The fan diffuser and collector is located in the annular chamber defined by the inner and outer end plate shields at one end of the machine. The fan diffuser includes a disk disposed in the radially inner portion of the annular chamber. An inboard surface of the disk is parallel to the adjacent surface of one of the shields. Both surfaces define a diffuser channel which receives substantially all of the gas flow expelled by a fan radially coextensive with the annular chamber. The disk is mounted on the other shield but has an outboard surface spaced away from that latter shield. The disk is foreshortened with respect to a frame wrapper which surrounds the stator and rotor of the dynamoelectric machine thereby forming a collector.

Abstract: Terminal boxes for large dynamoelectric machines provide a housing for high voltage terminal bushings which connect the dynamoelectric machine with a power grid. The stray flux from the terminal bushings induces eddy and circulating currents in the terminal box walls and consequent heating of the walls. To limit wall temperatures water is circulated through sealed flow channels fabricated to the terminal box walls and in series with the terminal bushings flow circuit. A preferred wall construction comprises an outer wall of stainless steel clad carbon steel and an inner wall of stainless steel.

Abstract: Information is recorded on a magneto-optic medium having a predominant proportion of preferred domain orientations with a substantial component normal to a recording surface thereof, by using a fringe field component from a magnetic-head. At least one magnetic head is utilized and such head is passed over the medium in a predefined track pattern which incorporates substantial overlapping of adjacent track portions. With such overlapping, only a residual portion of a track as originally laid down remains unerased in the final recording, and such residual portion is narrow in relation to head width. A high-resolution optical playback device is then preferably employed to extract the recorded information from the compact residual track.

Each of the slitter units is mounted to traverse the web from side-to-side either individually or simultaneously in response to a single driving means which adjusts the position of the slitter units across the web.

Abstract: The chucking device of the present invention comprises a tapered chuck plug with an elongated slot formed in the tapered end thereof into which a pair of core engaging chuck dogs are mounted. The chuck dogs are normally spring biased into a retracted position within the confines of the chuck plug but can be mechanically actuated to project from their slot outside the confines of the chuck plug to firmly grip the insides of a hollow core.

Abstract: An apparatus for cutting, sorting and stacking paper or the like in sheet form is disclosed which includes means for collecting packets of sheets in tandem on a collecting drum prior to discharging the collected sheets to the stacker. The basic components consist of a sheet cutting section, a sheet collecting section, a sheet slow down section and a stacker unit. In the tandem collect mode of operation, the length of the cut sheets must be less than one-half the circumference of the collecting drum and the drive ratio between the sheet cutting section and the sheet collecting section is set at 2:1. Packets of sheets containing an odd number of sheets are collected in tandem on the collecting drum with the use of air showers that are controlled by microswitches in an air shower control unit that is driven by the cutting drum.

Abstract: A paper jogging device is disclosed for stacking sheets of paper or the like into precise alignment directly onto a shipping skid. The device employs a jogger paddle that is flexibly attached to a rigid supporting means, and that is driven so as to be vibrated back and forth over its entire surface. The drive means comprises a plurality of thrust members which are actuated by a pair of synchronized rotating eccentrics employing a novel modified "scotch-yoke" coupling mechanism. The novel features of the jogging device are, (1) the entire surface of the paddle moves back and forth simultaneously, (2) the forward motion terminates at a predetermined fixed position with reference to the supporting means, (3) the acceleration and deceleration of the paddle is a simple harmonic motion requiring minimum driving power, and (4) the entire operation is very quiet.
