Abstract: A power tool guide having a tool plate adapted to receive a power tool. The plate has a power tool engagement clamp to engage a power tool and connect the power tool to said tool plate without the use of tools. The tool plate has opposed channels and a control lock. A support base has opposed guide rails, each of the guide rails has first and second ends. The tool plate has opposed channels that are removably mounted upon the support base opposed guide rails between the first and second ends. The channels allow the tool plate to slide upon opposed guide rails and to be easily removed from the rails. The control lock locks the tool plate with respect to the support base at a desired position along the opposed guide rails a spaced distance from the first and second ends. The support base has an edge extending from at least one of the guide rails adjacent one of the first and second ends.

Abstract: A wind turbine for capturing energy from a fluid flow comprises a rotor having a rotational axis and a plurality of rotor blades 104 arranged for rotation about the rotational axis. The rotor blades extend longitudinally in a direction substantially parallel to the rotational axis. A shield member V3 is arranged to shield some of the rotor blades from an oncoming wind where incidence of the wind on those rotor blades would act against rotation of the rotor in the direction of rotation. The rotor blades 104 are distributed about the circumference of the rotor and are spaced from the rotational axis, defining a substantially cylindrical space within the rotor through which the wind passes. The shield member V3 is defined by a radially inward surface and a radially outward surface. The radially inward surface follows substantially a portion of the circumference of the rotor. The radially outward surface of the shield member V3 comprises a first portion which meets the radially inward surface.

Abstract: A collapsible mobile bench has a work surface that has opposed ends and a middle section. The opposed ends are wider than the middle section. The middle section is adapted to receive a tool. The work surface is adjustable between collapsed and raised positions, with the work surface being positionable at infinite positions between the collapsed and raised positions. A set of wheels are mounted to the work surface for transportation of the work bench. The work surface can be used as a work bench or a tool support and collapsed for transport and raised to a desired height for use.

Abstract: A portable tool stand having automatically deployable legs. The tool stand has a body with a work surface and opposed ends. Deployable legs are pivotally mounted to the tool stand. The legs move between a stored position adjacent to the body and a support position wherein the legs are deployed to support the body. Retractable arms are mounted to each end of the body and slide with respect to the body. The deployable legs and the arms are operably connected such that sliding the arms with respect to the body moves the legs between the stored position and the support position.

Abstract: A tool support table having a support frame having opposed sides. A two sided work top mounted between the opposed sides of the support frame for rotation with respect to the support frame. The work top has a flat surface on one side and a tool support surface on the opposite side. The work top is rotatable with respect to the support frame to expose the flat surface or the tool support surface. The tool support table is generally cuboid shaped. The tool support table also includes a unique universal tool mount.

Abstract: A convertible ladder and scaffold assembly includes a plurality of uprights and a plurality of beams each extending from one of the uprights. A plurality of hinges each hingedly connect one of the uprights to one of the beams about a rotational axis (AR) to provide an assembly having ladder, scaffold, push-cart, and storage configurations. Each of the hinges defines catches and present a stop releasably engaging catches for preventing rotation about the rotational axis (AR). At least one lever bar releasably engages a plurality of the stops for simultaneously releasing a plurality of the stops from engaging catches. Each of the lever bars have a plurality of lever sections for providing leverage to disengage the stops from the catches. Each of the lever bars has a grip section interconnecting the lever sections for simultaneously releasing a plurality of the stops from engaging the catches.

Abstract: Apparatus for treating iron ore, comprising an elongate and generally cylindrical inclined kiln mounted for rotation about its longitudinal axis. A drive motor is coupled to the kiln to rotate the latter about that axis. A moving grate is positioned at the upper end of the kiln to feed iron ore pellets into the kiln while the latter is rotating. Port-defining means are provided in the generally cylindrical wall of the kiln to enable gaseous material to be fed into the interior of the kiln at at least one position between the ends thereof. The port-defining means are of such a construction that they are open when they are underneath the iron ore in the kiln. Gaseous oxidizing material feed means are connected to the port-defining means to feed such oxidizing material thereto, whereby oxidizing gaseous material is passed through the iron ore in the kiln when the apparatus is in use so as to raise the temperature of the iron ore, by oxidation thereof, and cause the latter to be indurated.

Abstract: In a continuous balling process, which may be the formation of green balls from iron ore, water and a binder in a balling drum as a stage in the pelletizing of iron ore, which includes a balling circuit in which undersized balls are recycled directly together with further raw material, the phenomenon known as surging is reduced by a method which involves including in the process a stage modifying the fundamental direct relationship between discharged undersize balls and those recharged, this unmodified direct relationship being the recurrence of the discharged balls identically as recharged balls after a constant time interval.
