Abstract: A clay target trap machine including a clay target throwing machine (1) and associated target hopper or magazine (2) mounted on a base, the base being mounted on a carriage (8) movable automatically on rails (12) and able to throw clay targets from more than one position and at a number of different firing angles and heights.

Abstract: A rotary wheel member for use in a rotary, friction type, continuous extrusion apparatus is produced by(a) producing a rotary wheel having formed in its cylindrical peripheral portion a continuous groove, and secured in that groove for movement with the wheel a solid annular metal mass;(b) rotating the wheel about its rotary axis; and(c) applying to the periphery of the annular metal mass a tool of predetermined end shape, and progressively advancing the tool in a radial direction as the wheel continues to rotate, thus machining in the peripheral portion of the annular metal mass a working groove of predetermined transverse cross section.

Abstract: A continuous extrusion machine in which feedstock in particulate or comminuted form is admitted to a peripheral groove formed in a rotating wheel member, is enclosed in that groove by a cooperating shoe member, is frictionally dragged along the arcuate passageway formed by said groove and a projecting portion of said shoe member towards an abutment member carried by said shoe member, and is continuously extruded as a metal product through a die orifice disposed at the downstream end of that passageway. A cooling device is provided downstream of the abutment member.

Abstract: A continuous extrusion machine, in which feedstock is admitted (at 50) to a peripheral groove (12) in a rotating wheel (10), is enclosed in that groove by a cooperating shoe (24), and is frictionally dragged along an arcuate passageway (48) formed by said groove and a projecting portion (30) of said shoe towards an abutment (36) carried by the shoe. The abutment tip and adjacent wheel parts disposed downstream of the abutment are cooled directly by a jet of cooling fluid issuing from a nozzle (64) carried downstream on the shoe. An annular band (FIG. 2, 74) of a good thermally-conductive metal embedded concentrically in the wheel enhances the cooling obtained. The extrusion apparatus yields a metal product (FIG.

Abstract: A continuous extrusion product issuing from a continuous extrusion apparatus is threaded through a treatment die (to change its cross-section) and is continuously drawn therethrough by a tensioning device controlled by a system which (a) senses the temperature of the product as it leaves the extrusion apparatus, (b) converts (in a function generator) a temperature signal so produced into a tension reference signal, (c) compares a tension feedback signal (derived from a sensor adjacent the extrusion apparatus) with that tension reference signal, and (d) controls the tensioning device in accordance with the difference of the tension reference and feedback signals so as to prevent the sensed tension in the product (extending between the extrusion apparatus and the treatment die) from exceeding a safe value which is less than the yield stress tension of that product at the sensed temperature.

Abstract: In a continuous extrusion machine in which feedstock is admitted to a peripheral groove in a rotating wheel, is enclosed in that groove by a cooperating shoe, is frictionally dragged along an arcuate passageway formed by said groove and a projecting portion of said shoe towards an abutment carried by said shoe, and is continuously extruded as a metal product through a die, is flash extruded through clearance gaps between cooperating wheel and shoe surfaces, is intercepted and broken off periodically in short lengths by teeth which project radially or transversely from the wheel, the arcuate passageway has a radial depth which progressively decreases in the direction of wheel rotation in a zone extending upstream from the abutment.
