  • Patent number: 6739268
    Abstract: A coil car has a pair of deep side sills and a trough structure mounted to, and suspended between, the deep side sills for carrying coils. The side sills extend between the rail car trucks and act as a pair of deep side beams for carrying vertical loads. The deep side sills are arranged to extend above and below the center sill of the coil car to give vertical stiffness to the coil car. The top chord members of the side sills are outwardly splayed relative to the bottom chord members of the side sills. Cross-bearers extend outwardly and away from the center sill to attach to the side sills. The trough structure has three parallel, longitudinally extending troughs—a central trough lying between two laterally outboard outer troughs. Each trough is shaped to cradle steel coils, or other similar loads, between its inwardly and downwardly sloping shoulder plates. The shoulder plates are lined with cushioning to buffer coils during loading or travel.

  • Patent number: 6560794
    Abstract: A rise assist apparatus comprising a handrail in the form of a convoluted section attached to a vertical pole, and stabilized by a bed frame attachment member and a floor contacting base frame. Alternatively, the rise assist apparatus may be wall mounted, being stabilized by a system of mounted wall brackets. The rise assist apparatus further includes an upper curved, horizontal leveraging handle, which extends from the pole-like support structure. Specifically, the rise assist apparatus allows the user to build momentum by pushing off the upper hand grip, and allows the user to control the momentum by regaining balance, and readjusting posture, by gripping the lower handrail member. Additionally, the user can use the curved grip with one hand, while simultaneously reaching for the handrail during the rising movement thereby allowing the user to support himself or herself as they rise out of bed.

  • Patent number: 6460401
    Abstract: The invention relates to a method of trace analysis of organic compounds which calls for the steps of setting a test piece in a flow cell, and thereafter removing organic compounds from the test piece by heating it at high temperature in an oven. The compounds are concentrated in a trap tube and then removed from the trap tube and carried into a concentrating/inlet unit, such as a thermal desorption cold trap injector. In this unit, cryofocusing of the compounds is performed, and then the organic compounds are introduced into a gas chromatograph to be analyzed therein, wherein a part of the purified inert gas is caused, except during the process of trapping the organic compounds, to flow into the flow cell from the direction opposite the direction from which the gas flows along the trapping line.

  • Patent number: 6390244
    Abstract: A brake wear indicator to provide visual and tactile indication of unacceptable brake wear. The brake wear indicator has a hub drive attached to a cam shaft, a brake wear disk attached to the hub drive and a body attached to a slack adjuster lever. The brake wear disk has a wear detector lug. The body has two the travel limit lugs which extend towards the centerline of the brake wear disk and are on the end of flexible fingers. When the brake linings are approaching unacceptable wear, the wear detector lug contacts one of the travel limit lugs and pushes the travel limit lug and the end of the corresponding finger away from the adjacent outer surface of the body. The rising of the end of the finger above the adjacent surface provides visual and tactile indication of unacceptable brake wear.

  • Patent number: 6328456
    Abstract: The present invention is directed to an LED lamp and method of using one or more lamps, and portable lighting products such as flashlights using such LED lamp(s). The LED lamp according to the invention provides uniformly distributed light that radiates spherically approximately 270° in all directions, both radially and axially. This newly designed lamp is ideally suited as a source of illumination for beam lights of the type employing reflective surfaces to produce a beam of light. The at least one chip is encased in at least one envelope surrounding the chip, with the envelope extending from a first position below the position of the at least one chip to a second position above the chip position. The second position of the envelope forms a lens in from of the at least one chip with the surface of the lens being configured and positioned relative to the ship such that a substantially uniform portion of light emitted from the chip is reflected off of the surface.

  • Patent number: 6318201
    Abstract: A motor vehicle differential bearing pre-load mechanism which provides for the simultaneous use of a collapsible spacer which plastically deforms and has a close to linear load to deflection band on one side of a motor vehicle differential assembly and a threaded adjuster on the other side of the motor vehicle differential assembly to axially pre-load the differential bearings in motor vehicle differential axles or on any shaft with bearings which requires an axial pre-load. Typically, the axial pre-load of the differential bearings decreases as wear of the differential bearings occurs when mechanical shims or a threaded adjuster without a collapsible spacer have been used.

  • Patent number: 6315841
    Abstract: Bevel gears having a carbon content of at least about 0.4% by weight, preferably 0.5% by weight are manufactured by a process which includes forging a steel blank having a carbon content of at least 0.4% by weight until a bevel gear precursor having essentially the tooth configuration and dimensions of the desired product gear is obtained, and hardening the teeth of the gear precursor by induction heating without machining of the teeth. The initial forging is precise enough so that no further machining of the teeth is required. This requires forging to a tolerance specified in AGMA class 6. The gear is then induction hardened, first by preheating at a lower frequency, say 10 KHz, then induction heating at a higher frequency, say 50 KHz, in order to obtain a desired hardness profile. The desired hardness profile includes the surface hardness of at least 50, preferably 60, on the Rockwell C scale and a core hardness not over Rockwell C 45, preferably from Rockwell 25 to Rockwell 40.
