  • Patent number: 6142295
    Abstract: A chain link conveyor belt carries lateral slats extending from the chain links, upon which are formed integral ribbed finger load carrying platform structure that interdigitates and overlaps their ribbed fingers with leading and trailing chain links in a conveyor belt. Wider belts are feasible when a parallel pair of spaced chains support the lateral slats extending horizontally from the chain links to the belt edges. The chain links are Y-shaped with elongated pivot rod slots in the leg to permit flexibility for laterally pivoting the belt around curved paths. Specially shaped structure on the slats near the belt edges supports long finger tip ribs of adjacent slats, thereby to strengthen the edge portions of the belt. The outermost fingers are reinforced to slide on guide rails. The trailing ribbed fingers diverge inwardly from the belt edges to avoid interference and fracture.

  • Patent number: 6057509
    Abstract: A modularized electric box system provides a minimum of modular elements, typically two or three from which a basic anchor box may be formed with protruding members for support by a building body, and from which gangable extensions thereto may be fashioned. The modules may constitute a basic open front electrical box frame having at least one open side with interlocking structure for receiving and supporting either a sidewall panel or a gangable U-shaped extension box module. An anchoring box may be formed with anchoring structure integrally protruding from end panels thereof adapted for attachment to a building body. Thus minimally a basic U-shaped box frame module without sidewalls interlockable with a similar module and a removable sidewall module interlockable upon a U-shaped box frame at the open sidewalls will form a gangable box system. Interlocking channelwork permits unimpeded insertion and removal of modules by sliding movement perpendicular to the open box fronts.

  • Patent number: 6020737
    Abstract: A rotary resolver having a stator housing with electromagnetic coils and a permanent magnetic rotor rotatable therein is improved to provide a resolver system with more precise angular rotor position readings. Interacting system features include a ring of soft magnetic material interposed between north and south magnetic pole structure on the rotor, which is enhanced in performance by a particular one of the soft magnetic materials RSi 24, RNi 8 and RNi 5. Adjustable compensation coil structure in the stator housing interacting with the rotor flux pattern obtains more precise angular readings in different working locations. A digital control system dynamically processes flux compensation information. Resolver units may be positioned at an end of a rotating shaft in a working position for detecting the angular rotation position of the shaft.

  • Patent number: 6003625
    Abstract: A rear-drive, ride-on tractor propulsion unit is provided for articulation with manually steerable utility vehicles wherein a hydrostatic trans-axle transmission couples a gasoline motor to individual ones of two drive wheels about which the propulsion unit framework is pivoted. The drive wheels rotate about fixed axially aligned non-rotatable axles, and are independently driven by belts from the two axles of the transmission. In this manner, equal torque drive to the respective wheels is applied in one drive mode to maintain a preferred straight line drive path for the propulsion unit. For manual steering over a curved path the tractor unit permits a steerable three or four wheel utility vehicle to be pivoted about its rear wheels. A hydrostatic trans-axle transmission drive provides forward and reverse gears and braking. A low center of gravity provided by small wheels is made feasible by faster rotation speeds than the transaxle speeds afford.
