Abstract: RAILWAY CAR ASSEMBLY COMPOSED OF A       SERIES OF ARTICULATELY INTERCONNECTED CARS     Abstract of the Disclosure A series of relatively lightweight, short articulately interconnected cars is disclosed for transporting trailers or other cargo containers on a railway.  The interior cars of the series include a center sill which constitutes a narrow width underframe and a length substantially equal to the length of a car, a pair of end sills connected perpendicularly to the center sill at opposite ends thereof and having a width extending beyond each side of the center sill, support members interconnecting the ends of the end sills with the center sill, and male and female portions of an articulated connector respectively attached to each end of a car.  End cars have one end, constructed similarly, but are provided with conventional semi-automatic couplings on the other end in place of a portion of the articulated connector.  The articulated connectors are mounted on a single conventional rail-way truck which spans the adjacent ends of interconnected cars and further supports the support members.  Special configurations of the cars are disclosed for use in a trailer-on-flatcar (TOFC) and container-on flatcar (COFC) environments.

Abstract: ABSTRACT     METHOD FOR INCREASING THE PRODUCTIVITY OF A WELL       PENETRATING AN UNDERGROUND FORMATION      A low-viscosity acid is injected into a fracture containing a high-viscosity fluid. The injection takes place through perforations in the casing or production tubing, and the acid follows fingering flow paths in the fracture. The perforations are widely spaced (at least 60 centimetres distance between the perforations) to prevent merging of these flow paths close to the well.

Abstract: ABSTRACT OF THE DISCLOSURE     A self propelled forklift vehicle having a frame formed by two spaced parallel longitudinal frame members and a rear transverse frame member.  The fork carriage is movable forwardly and rearwardly on the longitudinal frame members, along the path of the machine, and carries a fork tower and forks.  The forks can be forced below the vehicle to raise the vehicle up beneath the rear of a trailer for trans-port.  The vehicle's rear wheels, which steer and drive the vehicle, are closely spaced and tiltable from side to side to allow for rough terrain, with the operator seat and motor on opposite sides thereof to balance each other.  A manually operated split pulley drive allows creeping of the vehicle at a closely controlled low speed.  The fork tines include erectable rollers to support part of the vehicle weight when the forks carry a forwardly extended load, to prevent tipping.  A front gate causes discharge of the contents of a pallet onto the ground when the fork carriage is retracted.  An automatic centering mechanism returns the rear driving wheels to either front driving or rear driving position as selected by the Operator.

Title: Archer's bow with intermediately  pivoted limbs
Inventor: CALDWELL JOSEPH M
IPC: F41B5/00
Filed: 1979-10-18
Granted: 1982-05-04
Abstract: Abstract An archer's shooting bow comprises a pair of elongate resilient limbs, each disposed at a respective end of an elongate rigid handle riser assembly which has a central handle portion.  The limbs have outer tips at the opposite ends of the bow.  A bowstring is coupled between the outer limb tips adjacent the rear face of the handle riser assembly.          The bowstring has a nocking point adapted to be drawn from a rest position to a drawn limb-flexing position on application of drawing force thereto.  Mounting means connect each limb only at a location intermediate its length to the respective end of the handle riser assembly for hinging motion of the limb relative to the assembly about an axis disposed sub-stantially perpendicular to the plane in which the bowstring moves in being drawn from its rest to its drawn position.          The geometries of the mountings of the limbs to the assembly are such that each limb has an inner tip adjacent a front face of the handle riser assembly proximate the handle portion.          Tether means are connected between each limb inner tip and the handle riser assembly for constraining the inner tip from movement away from the assembly in response to application of drawing force to the bowstring.  As the bow is drawn, each limb flexes on both sides of its point of hinging connection to the handle riser assembly in a manner analogous to a simply supported beam loaded by a concentrated load at said location.          A bow having only one such limb and tether arrangement is also described.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for the direct production of steel from particulate iron oxides or concentrates including two major steps in which in Step (1) the iron oxides are converted to iron carbide and in Step (2) steel is produced directly from the carbide in the basic oxygen furnace or the electric furnace.          In the production of the carbide the oxides are reduced and carburized in a single operation using a mixture of hydrogen as a reducing agent and carbon bearing substances such as propane primarily as carburizing agents.  Iron carbide thus produced is introduced as all or part of the charge into a basic oxygen furnace to produce steel directly without the blast furnace step.  In order to make the steel making process auto-thermal, heat is supplied either by using the hot iron carbide from Step (1) or preheating the iron carbide or by including sufficient fuel in the iron carbide to supply the required heat by combustion.

This current supplying circuit includes a current detector for generating first and second detection signals of amplitudes proportional to the currents flowing in the ring and tip lines, respectively, a reference gen-erator for generating a reference signal, and a comparator for comparing the signal difference between the first and second detection signals and the reference signal so as to produce a signal in accordance with the compared result, thus a shorted-to-ground fault on the ring line or tip line being detected by monitoring the signal produced in accordance with the compared result.          After the shorted-to-ground fault is detected, the current supplying circuit is protected from breakdown.
