Abstract: An ion source configured for integration into both existing ion implanters used in semiconductor manufacturing and emerging ion implantation platforms. The ion source in accordance with the present invention includes the following features, all of which depart from the prior art to produce a well-focused, collimated and controllable ion beam. These features include: ionizing electron beams generated external to the ionization chamber, thereby extending the emitter lifetime; 90 degree magnetic deflection of electron beams such that no line-of-sight exists between the emitter and the process gas load, and the emitter is protected from bombardment by energetic charged particles; two opposed electron beams which can be operated simultaneously or separately; and use of a deceleration lens to adjust the final energy of the electron beam, substantially without affecting electron beam generation and deflection.

Abstract: A support structure has a number of posts with flanges and slots formed in the flanges. The support structure also has a number of aprons with end tabs that are inserted into respective post flange slots. A gap defined by the apron end tabs and an edge of the apron creates an interference fit with a slot lip of the flange slot. The disclosed interlock of the aprons to the posts creates a stable support structure that has aesthetic value. The disclosed interlock further provides the capability of creating various support structures (e.g., shelving assemblies, workbenches, cabinets, storage assemblies).

Abstract: An electrical fuse comprises a fusible ribbon having one or more weak spots along its axial length which is highly resistant to mechanical fatigue caused by cyclic heating and cooling of the fusible ribbon. The weak spot comprises a series of apertures arranged in a curvilinear or angular configuration extending transversely to the axis of the fuse ribbon between the opposite sides thereof. Centers of adjacent apertures of the series are offset from each other with respect to the axis of the fusible ribbon by a distance at least equal to the shortest distance between the geometric center and the peripheral edge of any one of the adjacent apertures such that the cross-sectional area of the weak spot is distributed transversely across the fuse ribbon.

Abstract: A floor treating machine adapted to operate as a floor scrubber and a floor polisher or buffer includes a main housing or support frame structure from which extends a brush housing assembly. The main housing contains a combined solution and recovery tank, a motive device to power the floor treating machine, a propulsion system to propel the floor treating machine along the floor, a pneumatic power system, a squeegee subassembly and electrical and pneumatic control systems therefor. The brush housing assembly is operatively connected to the main housing by a brush lifting mechanism such that two brushes selectively rotating in opposite directions in the brush housing assembly can be lifted away from the floor or moved toward the floor so that the brushes exert the correct amount of pressure against the floor depending on the job being done.

Abstract: An indicating fuse is provided with an indicator at the free end of a movable spring contact, the indicator being located at an angle with respect to the plane of the spring contact. Provision is made for lower rated fusing currents utilizing the same basic fuse structure by forming a slot in the flexible spring contact at the point of maximum bending. A rounded shoulder is formed on the fuse carrier body across which the spring contact member is bent to minimize breakage and damage. The flexible spring contact is integrally formed with a U-shaped terminal that mounts it on the fuse carrier body, a second substantially identical generally U-shaped terminal also being secured to the fuse carrier body to provide a fixed contact. Molded ribs are formed in the insulating material of the fuse carrier body adjacent the open ends of the U-shaped terminal members to prevent the terminals from pinching together to form an undesired tapered configuration.

Abstract: A fuse mounting arrangement for a pad mounted underground electrical power distribution systems includes at least one fuse panel which is slideably mounted by means of slide bearing assemblies in a housing enclosure. The fuse panel is removably mounted on the slide bearing mounting channel by means of cooperating tabs, slots and C-shaped loops or eyes. Should a fuse panel or its associated power fuse require replacement, safety interlock means including fixed locking pins and a cooperating U-shaped handle having hooked portions for engaging the locking pins are provided. It is imperative that the fuse panel and its fuse be electrically isolated prior to removal or withdrawal of the same from the housing enclosure. Therefore, the fuse elbow connector and its associated line conductor are disposed in front of the handle which is pivotably mounted upon the fuse panel between a locking position and a release position.

Abstract: A unique design and construction is presented for the rotor of a dynamoelectric machine. The rotor is comprised of two end plates, bar means for holding the end plates together, a stack of pole laminations, electrical conductors wrapped about the laminations and an insulator means. The end plate contains apertures about its periphery such that the rotor can be balanced about two axis perpendicular the rotor axis of rotation by inserting masses/weights into the apertures. The insulator means electrically insulates the electrical conductors from the ends of the stack laminations, the rotor end plates and the rotor shaft. The insulator means by its unique shape further acts as a guide to position electrical conductors about the laminations during pole winding. In one embodiment the insulator means acts as a thermal insulator protecting electrical conductors when the bar means are welded to the end plates.
