Appl. No.:

7/126342

Inventors:

Raymond A. Hanson - Spokane WA

Assignee:

R. A. Hanson Company, Inc. - Spokane WA

International Classification:

B03B 510

US Classification:

209425

Abstract:

A mechanical drive mechanism is designed for imparting pivotal motion to the frame arm or walking beam of a mineral jig. Rotary cam action is employed to mechanically pivot the walking beam or frame arm which supports a cone and flexible diaphragm at one end for imparting jigging action to the jig bed. Adjustment features are preferably provided to enable the amplitude of the reciprocating motion imparted to the diaphragm and cone to be selectively varied. In the preferred embodiment, the cam is constructed to be pivotal when at rest for enabling the amplitude of the camming action, and correspondingly the pivot stroke, to be varied.

International Classification:

US Classification:

Abstract:

A slipform for lining upright shafts with monolithic concrete by pumping concrete downwardly under pressure to a slipform apparatus to simultaneously move the slipform apparatus upwardly within the shaft while concrete is being formed continuously into a monolithic lining within the shaft. The apparatus includes outer and inner slipform members. The outer member includes a sealing mechanism by which the area above the outer slipform is hydraulically sealed from the area below. The inner slipform fits within a conical recess of the outer slipform and includes a lower cylindrical portion for forming the open inside diameter of the lining. Concrete, in a plastic, wet condition, is pumped under pressure between the two slipform members to be molded against the shaft wall into an upwardly open monolithic concrete lining. Since the concrete is pumped between the two forms under pressure, a reaction force is created that operates upwardly against the slipform members. The concrete will thus act to push the forms upwardly within the shaft as it is pumped through the forms.

US Classification:

Abstract:

A bidirectional excavator capable of excavating a predetermined swath of earth while moving in a forward or rearward longitudinal direction. The excavator includes a rotatable excavator wheel that operates to disengage and move loosened earth to a centrally located transverse conveyor belt. The belt carries the loosened material to one side of the excavator. Retractable crumbing blades are located on both forward and rearward sides of the excavator wheel. Each is selectively operable to be lowered to an operative position adjacent to the wheel with regard to the selected direction of movement for the machine. The lowered crumbing blade serves to gather and maintain material sloughed from the wheel against the wheel so it may be eventually carried to the discharge conveyor. When it is desired to move the excavator in an opposite direction, the operative crumbing blade is retracted and the previously inoperative plate is extended to its operative position. Design of the excavator wheel is such that it may be rotated in the same direction regardless of directional movement of the machine.

Abstract:

A transportable submerged breakwater is described. The breakwater includes a pair of vertical parallel concrete walls spaced apart from each other. The walls have floatation cells containing buoyant means. The walls have a density slightly less than that of sea water and float in a substantially submerged condition with a top horizontal wall edge at or slightly above the water surface. Rigid members space the walls and rigging means provide tension to hold the walls against the rigid members.

International Classification:

B03B 556

US Classification:

209455

Abstract:

A preferred mineral jig apparatus includes a jig tank having a laterally oriented piston and cylinder assembly mounted therewithin. The piston and cylinder assembly defines two compartments, with reciprocating motion of the piston causing pulsating action of the water within the two respective compartments. The piston and cylinder assembly includes a cylinder, a piston assembly and a piston rod connected to the piston assembly. The piston rod includes an internal channel to convey make-up water to the tank from an external water source. The piston rod is supported for lateral reciprocating motion by at least two downwardly hanging leaf springs. The piston assembly comprises a pair of separated piston plates oriented transversely relative to the cylinder. The separated piston plates defining a space therebetween as well as a separation distance between the piston plates. The piston rod is connected to one of the piston plates.

Inventors:

Raymond A. Hanson - Spokane WA

International Classification:

E21D 500

US Classification:

425 59

Abstract:

A slipform apparatus is described for forming a continuous upright monolithic lining within a preformed upright shaft. The slipform is provided in three independently movable sections that may be lowered into the shaft. Wet concrete is delivered to the sections and dispensed outwardly of the sections to form the lining. The formed sections hold the wet concrete against the walls of the shaft and progressively form a cylindrical upright bore within the shaft. As concrete is delivered to the slipform, the individual sections are moved in an "inchworm" effect in conjunction with an expansion mechanism to automatically lift itself upwardly within the shaft as the lining is being formed. A steering mechanism is provided to enable selective angular movement of the slipform in a nonvertical plane.

International Classification:

E02D 2910
E03F 306

US Classification:

405146

Abstract:

A system is described whereby a large elongated monolithic conduit is formed within an excavation of a single continuous pour of concrete. The open core of the conduit is formed by an interconnected group of tubular form members, forming a static line within the excavation. The system includes a slipform mechanism that is progressively moved along the static line, molding wet concrete about the inner form sections. Successive inner form sections are disconnected from the rearward end of the static line (after the adjacent formed concrete has hardened), reduced in cross-sectional dimension, and transported forwardly through the static line to a forward conduit end. There the individual sections are expanded, cleaned and reattached to the front of the line as the slipform moves along. The successive inner form sections are disconnected, moved forwardly and re-expanded by a self-steering wheel supported transporter. The transporter is powered to move longitudinally within the static line.

Abstract:

A header adjusting system for a hillside combine harvester includes a master hydraulic cylinder assembly and a slave hydraulic cylinder assembly. The master hydraulic cylinder assembly is slaved to movement of the wheels relative to the combine frame. The slave hydraulic cylinder assembly is slaved to extension and retraction of the master hydraulic cylinder assembly. The slave hydraulic cylinder assembly causes the header to pivot about the longitudinal axis of the harvester in order to follow the contour of the ground. A header trimming mechanism is also provided to enable direct operator control of some of the pivoting action of the header about the longitudinal axis. A leveling system for a hillside combine harvester includes a cable and a biased, moveable reference pulley associated therewith. Movement of the reference pulley actuates a switch which selectively imparts fluid flow to hydraulic leveling cylinders to re-establish a reference position of such pulley, and correspondingly a reference orientation of such cylinders. A chain drive system for a hillside combine or other vehicle includes a first arm and second arm, at least one of which is mounted for pivotal movement relative to the other.
