Abstract: ABSTRACT OF THE DISCLOSURE        An efficient, portable, easy to operate tool employing a linear motor is disclosed that is powered by the gases produced from the internal combustion of a fuel and air mixture.  A supply of liquified gas stored under pressure in a cylinder provides the source of power.  The linear motor is slidably mounted within a cylinder to move reciprocally downwardly and upwardly through a driving and return stroke.  A combustion chamber is formed at the upper end of the cylinder.  A spark plug powered by a piezo-electric firing device is located within the combustion chamber.  The combustion chamber features a turbulence generator, such as a fan, driven by an electric motor which is continuously in operation when the tool is in use.  A main valve mechanism actuated by a set of lifting rods that are moved upwardly and downwardly when the tool is moved towards and away from the workpiece, is used to control the opening and closing of the combustion chamber and to control the flow of fresh air through the combustion chamber.  When the combustion chamber is isolated from the atmosphere and the fuel and air are thoroughly mixed, the spark plug is fired to explode the fuel and air mixture and force the linear motor through its driving stroke.  The linear motor is returned to its driving position by a spring or air acting against the underside of the linear motor.  The unique use of the electric fan improves the overall operational efficiency of the tool and the utilization of the liquified combustible gas.

Abstract: ABSTRACT OF THE DISCLOSURE             A feed mixing apparatus for use wherever livestock is cared for and fed.   The apparatus has a frame positioned by the user adjacent to a supply conveyor for feed constituents and a delivery conveyor for mixed feed.  A hopper unit for selectively receiving feed constituents or discharging mixed feed is sup-ported by the frame.  A  rotatable cylindrical drum with internal spiral mixing and conveying blades is mounted on the frame.  The hopper unit is connected to the front of the drum by a cylindri-cal pipe having front and rear upwardly opening semi-cylindrical segments.  An auger shaft extends from the hopper unit and through the pipe into and through the drum axially of the spiral blades. A drive means on the frame provides for unidirectional rotation of the drum so that the spiral blades are always moving feed constituents to the front of the drum.   The drive means also provided for selective bidirectional rotation of the auger shaft for moving feed constituents from the hopper unit into the drum or for moving mixed feed from the drum into the hopper unit. Within the drum, paddle elements continuously direct feed con-stituents or mixed feed onto a rear pipe segment for movement by the auger shaft into or from the drum.

Abstract: ABSTRACT   Mineral impact breaking apparatus uses a divided flow with the first part of the flow being accelerated preferably through a rotor and discharged towards an impact breaking surface.  The second part of the mineral flow is introduced into the path of the accelerated first part of the flow so that there is impacting between the first and second flows of minerals and with the second flow acting as anvil blocks against which the first flow particles will be impacted and broken.  Where the horizontal accelerating rotor is used to accelerate the first part of the mineral flow the kenetic energy of the rapidly rotating air above the rotor is used to direct an air flow back to the infeed of the rotor and minimise dust discharge.
