    摘要： The rotor of an electrical motor, such as a hybrid permanent magnet stepping motor or a variable reluctance motor is assembled on a rotor shaft, and includes at least one lamination stack and a pair of supporting bearings, with the outer diameter of the bearings being slightly larger than that of the lamination stack. A stator is assembled from a stator lamination stack including a pole configuration and a pair of unmachined end caps registered and secured to the lamination stack such as by thru bolts. The registered stator assembly is potted to unitize the assembly, fixing the relationship between the end caps and the lamination stack, and providing a smooth continuous bore through the center of the stator assembly. The thus potted assembly is machined as by diamond lapping to form a continuous bore accurately machined through the center of the stator, concurrently forming bearing surfaces in the end caps and an intermediate machined section in the lamination stack. The rotor assembly is inserted into the stator assembly, with the machined bore providing bearing mounting surfaces in the end caps and an air gap for rotation of the rotor in the lamination stack.

    摘要： A universal vibratory feeder has a removable tray provided with a continuous serpentine path. A plurality of carriers are received in the path, and articles of manufacture are carried by the carriers around the path in the tray. A vibrating platen beneath the tray has a plurality of bristles engaging the bottom of the respective carriers. The bristles are oriented in the direction of travel of the carriers around the path. The path in the tray is formed by a continuous through opening which separates the tray into two portions. The carriers straddle the thickness of the tray and are in substantial abutting relationship to one another throughout the path, thereby precluding the tray portions from separating.

    摘要： A portable apparatus adapted for use in filling chuck holes in paved surfaces with a sulphur-based material that has been heated to a plasticized condition. The apparatus includes an electrically heated furnace in which an auger is mounted for the purpose of moving a sulphur-based material through the furnace at a controlled rate (e.g., about 2 feet per minute), such that the material will be elevated to a temperature of above 305 degrees Farenheit (the melting point of sulphur) to produce a tenacious filler material. The furnace is heated by tubular resistance heaters that are bent in a spiral fashion around a mandrel, so that they may be placed in intimate contact with the exterior of a tube which constitutes the core of the furnace. The furnace is fed by a hopper that is mounted above the entry point for the auger, so that dry material may be fed--by gravity--into the furnace whenever a gate-valve mechanism is opened. The furnace and its hopper are relatively light weight, typically weighing only about 360 pounds, and are readily moved about by one person when supporting wheels are installed on the bottom of a frame that supports the furnace. A tandem-axle trailer provides an optimum way of transporting the furnace and the ancillary materials and equipment that are used with the furnace, e.g., a portable generator, a small air compressor, bags of the hole-filling material, etc.

    摘要： Methods, systems and computer program products for filtering generally-broadcast messages received by a movable unit based on current spatial position, stored trajectory history, and probable future trajectories. A current spatial position of the movable unit is received and stored to form a stored trajectory history. A generally-broadcast message relating to a target geographical region is also received and stored. Potential trajectories of the movable unit are then computed over a pre-determined time based on at least one of the current spatial position, a current travel direction of the movable unit, and the stored trajectory history of the movable unit. The generally-broadcast message is then disseminated in response to at least one potential trajectory crossing into the target geographical region during the pre-determined time period. The generally-broadcast message may also be disseminated on the basis of specified user preferences.
