Abstract: An attachment including a duct having an air inlet for receiving an airflow from a hair styling apparatus, at least one vane located within the duct for directing the airflow towards an air outlet and the air outlet is elongate in shape and orientated generally parallel to the direction of airflow at the air inlet.

Abstract: A conveyor including a chain flight conveyor superimposed over an elastic belt conveyor. The juxtaposition of the two conveyors results in longer wear and less erosive friction when compared to sole chain flight systems.

Abstract: An apparatus for continuously conveying ore and the like. A penetrator, rotatably disposed about a common coaxial horizontal axis shared by the forward section of a first conveyor, fluidizes a muck pile to continuously load material onto the first conveyor. Actuators for independently oscillating the penetrator and independently positioning the first conveyor are provided. An optional second conveyor may be employed to transport the material away from the first conveyor.

Abstract: An apparatus and method for continuously conveying ore and the like. A penetrator, rotatably disposed about a common coaxial axis shared by the forward section of an endless conveyor, fluidizes a muck pile to continuously load material onto the conveyor. The conveyor, hinged approximately amidships, is mounted above a movable frame. Actuators for independently oscillating the penetrator is provided.

Abstract: Loading apparatus having vehicle body, inclined conveyor assembly extending upwardly and rearwardly from front of vehicle body, and hopper adjacent front of vehicle to direct material onto conveyor. Apparatus has extendable excavating assembly including a guide mounting a carrier which carries a hoeing assembly. The guide is mounted on vehicle body, and the carrier means cooperates with the guide for movement parallel to movement of conveyor when viewed from above. The hoeing assembly is carried on carrier means to be generally adjacent the hopper to draw material onto hopper for feeding onto conveyor. Carrier and guide can be carriage mounted on rails, or telescoping ram arrangement to provide extendable mount for hoeing assembly which increases reach thereof without requiring excessively long arms, and also facilitates operation of hoeing assembly for drawing material onto the hopper. Operator is positioned at front of vehicle for good visibility during operation of hoeing assembly.

Abstract: Reversible puller for quickly pulling drill rods from, or for re-inserting drill rods into, drill hole. Rock drill has drill head mounted on feed carriage, drill head including rod rotating structure for rotating drill rod when in drilling mode. Rod puller includes drive wheel and idler wheel mounted for rotation with peripheries adapted for engagement with drill rod. Drive wheel is coaxial with, and rotates with, rod rotating structure and idler wheel cooperates with drill head for movement relative to drive wheel to permit idler wheel to be positioned so as to be essentially coplanar with drive wheel with wheel axes parallel. Drill head is swivellably mounted on carriage to permit drill head to be positioned in rod pulling mode wherein wheel axes are disposed generally normally to drill rod axis and periphery of drive wheel is spaced closely adjacent drill rod. Idler wheel is moved so that drill rod is squeezed between idler and drive wheels for moving rod in desired direction.

Abstract: Core sampling drill head having powered drill chuck with jaws to grip drill rod. Head has thrust member movable by chuck actuating means between jaws retracted and jaws extended position, and precompressed chuck springs cooperating with thrust member and drill chuck so as to be movable with thrust member. Thrust member is located by releasable locking means in desired position, which means also relieve drill bearings of reaction from chuck springs. When thrust member is in jaws retracted position, chuck springs are precompressed by tension means and relatively large diameter tools can pass drill chuck. When thrust member is in jaws extended position, chuck springs cooperate with chuck, are further compressed and extend jaws to grip rod, and tension means are relieved of load from chuck springs. By precompressing and moving springs by themselves, worn drill rods can be accommodated in relatively short drill head without loss of grip.

Abstract: Feed frame assembly for supporting and feeding drill head which rotates drill rod about axis. Assembly includes spaced front and rear end members, laterally spaced longitudinal members and first and second hydraulic feed cylinders. Longitudinal members and feed cylinders extend between end members and are parallel to rod axis. Piston rods of feed cylinders have double-acting pistons cooperating with cylinder bodies to feed head along the piston rods. Stabilizer cylinders in longitudinal members force bearing pads against rock face to counteract the drilling forces. Head mounting means secures rigidly one side of drill head to first cylinder body, and secures releasably with latch opposite side of head to second cylinder body. When latch is released drill head can swing outwards about first piston rod, and when engaged mutual actuation of feed cylinders moves drill head along rods. With head swung out, first cylinder is hydraulically locked to divert fluid to second cylinder.
