US Patent:

44203900, Dec 13, 1983

Filed:

Jan 25, 1982

Appl. No.:

6/342154

Inventors:

Ronald Carr - Farmington MI

International Classification:

B03C 114

US Classification:

209216

Abstract:

A magnetic separator for particulates containing prime material and ferrous particles includes a housing having a removable cover having a central throated inlet along its length. A pair of vertically and laterally displaced hollow metallic rolls are journaled upon the end walls and extend the length of the housing, and enclose an elongated semi-cylindrical permanent magnet within each roll, the magnets being of opposite polarity. A pair of elongated, vertically and laterally displaced flow control dampers extend along the length of the housing and are pivotally mounted thereon and define with the inlet and rolls a vertical first feed path for the particulates. A first elongated hopper underlies the first flow path and has an elongated outlet overlying a first conveyor for receiving and delivering prime materials from the housing. Second and third elongated hoppers are arranged upon opposite sides of the first hopper under the rolls respectively. Additional conveyors underlie the second and third hoppers for delivering ferrous particles outwardly of the housing.

US Classification:

Abstract:

A machine is provided for assemblying the elements of a truss and fastening them together in a positive manner. A supporting table is made up of channel elements which have platforms thereon which are movable upwardly and are adjustable in a horizontal plane toward and away from the center of the table. A carriage runs upon spaced tracks to locate pressure plates which are mounted on a pair of like C-frames which are adjustable toward and away from each other so as to be effective for trusses of different heights. The pressure plates are moved toward each other and apply a substantial pressure for inserting a multiplicity of nails of a nail plate into the areas in which the members of the truss are to be secured together. This provides a truss of exact shape and dimension which is positively secured together and, where necessary, is provided with a rectangular opening in which a heating and/or cooling duct is supported.

Appl. No.:

6/382137

Inventors:

Ronald Carr - Farmington MI

International Classification:

B03C 126

US Classification:

2092232

Abstract:

A magnetic separator for mixtures of powdered plastic and metal comprises a housing having an inlet, a base plate and side plates. A plurality of vertically spaced staggered rows of laterally spaced pilot tubes span, extend through and are secured to the side plates to define a circuitous material falling path. An upright tube clearance plate is arranged intermediate the side plates and has a corresponding plurality of vertically spaced rows of laterally spaced apertures, oversized with respect to and loosely receiving the tubes defining clearance apertures. The clearance plate defines on one side an upright plastic feed chamber having an outlet in the base plate. An upright wiper plate is arranged between the clearance plate and one side plate having a corresponding series of apertures snugly receiving the tubes and defining with the adjacent side plate an upright metal feed chamber having an outlet. The elongated magnetic assembly is slidably mounted upon and intermittently reciprocal within each tube and is normally positioned within the plastic feed chamber. Falling particles of plastic cascade over the tubes within the plastic feed chamber for delivery through its outlet.
