  • Publication number: 20220162006
    Abstract: A modular noseroller assembly for transitioning a conveyor belt at an end of a carryway comprises a plurality of roller-mounting modules connected to a spacer element to form a noseroller assembly that can be installed in a conveyor frame. The roller-mounting modules mount freely-rotating rollers on an axle extending through the plurality of roller-mounting modules. The configuration and size of the noseroller assembly can be easily modified depending on a particular application.

  • Patent number: 7494006
    Abstract: A modular conveyor belt and belt attachment members that are retained by hinge rods. The attachment members have a body with opposite outer and base surfaces. Interaction elements, such as high-friction surfaces, plates, or holddown wings, extend from the outer surface. The base surface mounts flush against a conveying surface or an opposite surface of the belt. Legs extend directly from the base surface into gaps between hinge elements extending longitudinally outward of conveyor belt modules forming the belt. Feet at distal ends of the legs hook under hinge rods to retain the attachment member firmly in place. The lateral spacings between the legs are related to the geometry of the hinge elements to register the attachment element with respect to the belt.

  • Patent number: 7070043
    Abstract: A modular plastic conveyor belt having an A-shaped edge portion in belt edge modules along each belt row for tight collapse of the belt at the inside of a turn. The A-shaped region comprises two alternating series of laterally spaced links, each extending from opposite ends of the edge module. Each of the first series of links forms an acute angle measured clockwise from the direction of belt travel. Each of the second series of links forms an acute angle measured counterclockwise from the direction of belt travel. The angles decrease monotonically with distance inward of the first side of the belt edge. Laterally extending webs join the ends of consecutive converging links along an end of the module. The lateral extent of the webs increases monotonically inward from a first side edge of the belt. A cross bars extends between each pair of web-joined links.

  • Patent number: 6837367
    Abstract: A modular plastic conveyor belt having a central beam along each belt row. The beam extends laterally across the width of a belt row and includes a linear portion in a middle region of the belt and a sinuous region near both side edges of the belt. In the linear region, the beam includes a portion of constant thickness with linearly tapering portions toward the side edges of the belt. In this way, the thicker portions of the beam in the middle of the belt provide beam strength to allow less frequent support beneath the belt and the thinner sinuous portions at the edges of the belt give it the flexibility and mobility to collapse at the inside of a turn.

  • Patent number: 6719127
    Abstract: A sprocket drive system for a modular conveyor belt that compensates for drive-shaft twist under load. The drive system includes a plurality of belt drive surfaces spaced apart across the width of the underside of each row of a modular conveyor belt. A drive shaft supports a group of sprockets at spaced-apart locations. Sprocket drive surfaces are spaced apart circumferentially around the peripheries of the sprockets and arranged in rows across the sprocket to engage corresponding belt drive surfaces in the belt rows. The belt is wrapped around the sprockets on the drive shaft. The engagement of the sprocket drive surfaces with the belt drive surfaces drives the belt. Either the sprocket drive surfaces or the belt drive surfaces, or both, in each row are arranged in an out-of-phase relationship with each other when the conveyor belt is at no load. Once the conveyor belt is operating at load and the shaft twists, the drive surfaces assume an in-phase relationship for improved belt driving and tracking.

  • Patent number: 6554129
    Abstract: A conveyor belt and an attachment element that firmly interlocks into a row of the conveyor belt. In one version, the attachment element includes a base from which two sets of hook-shaped appendages extend. The appendages each include a shank portion extending from the base and a hook portion angling from the shank portion to a distal end. The hook portions of the first set extend in different directions from the hook portions of the second set. Belt modules in the interconnected rows of the conveyor belt have receptacles that open onto an outer surface of the belt. The receptacles are shaped to receive the differently-directed appendages. Blocking surfaces bounding the receptacles constrain the differently-directed appendages against removal. In another version, the attachment element includes a flange that extends outward in a different direction from a set of appendages.

  • Patent number: 5106770
    Abstract: In the fabrication of a junction field effect transistor, specifically a static induction transistor, an epitaxial layer of high resistivity N-type silicon is grown on a substrate of low resistivity N-type silicon. A plurality of elongated parallel grooves separated by interposed ridges are formed by reactive ion etching. A layer of silicon oxide is grown on all exposed surfaces including the side walls and bottoms of the grooves. Fluorine is ion implanted into the silicon oxide. The grooves are filled with deposited silicon oxide or polycrystalline silicon, and material is removed to form a flat planar surface with the silicon at the surfaces of the ridges exposed. P-type doping material is ion implanted into alternate (gate) ridges. The wafer is heated to diffuse the P-type doping material and form gate regions. Heating also activates the implanted fluorine ions which react with unbonded silicon atoms at the silicon oxide-silicon interface thus quenching vacant bond sites.

  • Patent number: 4331463
    Abstract: A self-centering device supports a generally cylindrically shaped workpiece. A pair of parallel, substantially horizontal shares are mounted within a mounting frame and traverse an opening therewithin. A pair of rolling bearings are adapted for reciprocating movement axially along the two shafts, respectively, with a first connecting rod coupled to the two bearings, so that the resulting rod and bearings can be reciprocated in the direction parallel to the axes of the shafts. In similar fashion, two other rolling bearings are adapted for reciprocating movement axially along the shafts, respectively, with a second connecting rod coupled to the latter bearings so that the resulting rod and latter bearing combinations can be reciprocated in the direction parallel to the axes of the shafts. A first connecting rod bearing is adapted for reciprocating movement axially along the first connecting rod. A second connecting rod bearing is adapted for reciprocating movement axially along the second connecting rod.

  • Patent number: 4110090
    Abstract: A process is described for forming glass optical fibers by heating a glass composition to vaporize a component of the composition at the surface to reduce the refractive index of the glass surface. Four alternative processes can be used: heat treating a fiber preform followed by drawing the fiber, simultaneous heat treating and fiber pulling from a glass melt, fiber pulling followed by heat treating or heat treating the surface of a melt followed by drawing a fiber or preform so that the surface of the melt comprises the cladding.

  • Patent number: 3963639
    Abstract: A fluorescent lamp having a phosphor coating on the inside surface of the tubular glass envelope, the phosphor coating comprising finely divided phosphor particles coated with a glassy phosphate material. The lamp is prepared by providing an aqueous slurry of the phosphor particles in a solution containing a material yielding a phosphate glass upon firing, coating the interior envelope walls with the aqueous suspension, and firing the phosphor coating at a temperature which promotes the formation of the phosphate glass coating about the particulate phosphor material. A suitable phosphate glass-yielding material is ammonium dihydrogen phosphate, and phosphor coatings produced therewith have been found to have improved adherence to the envelope walls.
