Title: Anti-sway reeving system
Inventor: LONG HERBERT D JR
IPC: B66C19/00
Filed: 1991-08-14
Granted: 1996-04-30
Abstract: A reeving apparatus for a crane having an overhead frame, a lifting beam subject to swaying forces, and a winding drum mounted on the frame for raising and lowering the lifting beam.  First, second, third and fourth spaced apart rotatable sheaves are mounted on the lifting beam for supporting the lifting beam.  The first and second sheaves are spaced apart in directions horizontally transverse to a longitudinal axis of the drum.  The third and fourth sheaves are positioned generally below opposite ends of the drum.          Alternate ones of the sheaves comprise single sheaves having first and second grooves and the other ones of the sheaves each comprise a pair of sheaves each having single grooves.          A plurality of ropes are affixed to the drum and to the overhead frame, and each one of the plurality of ropes is wrapped around one of the sheaves for supporting the lifting beam together with the sheaves.  The plurality of ropes includes first and second ropes extending to and wrapping around the same alternate one of the sheaves in one of the first and second grooves for generating friction forces with the alternate one of the sheaves in response to swaying movement to thereby dissipate swaying energy.  The first and second ropes also each wrap around a single groove of a pair of sheaves of a different other one of the sheaves for supplying rope to the alternate ones of the sheaves to allow limited swaying movement of the alternate ones of the sheaves.

Filed: 1991-12-20
Granted: 1997-07-22
Abstract: A process is provided herein for the preparation of ammonia synthesis gas by steam reforming and/or partial oxidation of a hydrocarbon feedstock. Such process includes the further steps of catalytically converting a part of the synthesis gas to methanol. Such prepared methanol is liquified and separated from remaining nitrogen-rich gas.

Filed: 1993-04-29
Granted: 1996-08-13
Abstract: Fuel is burned in accordance with a burning method and apparatus in two stages and in the presence of first and second oxygen-containing gases, respectively.   The     second oxygen-containing gas has a higher concentration of oxygen than the first oxygen-containing gas.  The fuel stream is burned in a first of the two stages at a first equivalence ratio sufficiently greater than 1.0, so that thermal NOx formation is inhibited, a more heat transfer effective luminous flame is achieved and a combustible mixture comprising unburned and partially oxidized fuel and fuel radicals is are produced for combustion in the second of the two stages. The combustible mixture is burned in the second of the two stages   at   an equivalence ratio of no greater than about 1.0 so that maximum heat is transferred to the first of the two stages to stabilize combustion therein, and the fuel radicals are sufficiently oxidized by the second oxygen-containing gas to inhibit formation of prompt NOx.

Abstract: A cable of this invention includes a core comprising a plurality of coated optical fibers and a filling composition of matter which is disposed about the fibers. Typically, the fibers and the filling material are disposed within a tubular member which is disposed within a sheath system. The sheath system includes longitudinally extending strength members and a plastic jacket. The filling composition which fills interstices in the core is one which includes an oil constituent which is a relatively high molecular weight aliphatic hydrocarbon. The aliphatic hydrocarbon is a synthetic oil such as polyalphaolefin or mineral oil. A relatively large percent by weight of an antioxidant system is used to prevent thermal oxidative degradation of the filling material as well as of materials in contact with the filling material. Advantageously, for stabilization and metal deactivation, the composition includes zinc dialkyldithiophosphate or diaryldithiophosphate. A styrene-ethylene propylene copolymer is also included in order to reduce oil separation of the filling material. A fumed silica is used to impart gel properties to the material.

Granted: 1999-01-19
Abstract: An energy absorbing device for use alongside a roadway to decelerate an impacting vehicle includes first and second elements.  The first element extends in an axial direction and includes a threaded portion that defines a multitude of projecting ridges.  The second element is movable relative to the first element in the axial direction, and the first and second elements are sized to create an interference fit such that relative axial movement of the second element applies a shear load to the first element to progressively deform successive ones of the projecting elements.  This progressive deformation of the projecting elements retards relative axial movement between the first and second elements.
