Abstract: A nonconductive holster for use with an electrical meter is disclosed. The nonconductive holster comprises a protective guard for preventing a person who is using the electrical meter from coming into contact with any exposed power sources being measured with the electrical meter. The nonconductive holster is fabricated of a nonconductive resilient material which provides the electrical meter with a protective coating in the event that the electrical meter is accidentally dropped or inadvertently struck.

Abstract: There is provided by the present invention a speed changing apparatus having a housing mounting a plurality of inwardly directed, circumferentially disposed teeth, preferably in the form of a ring gear. The housing has a hub that rotatably receives at least a first shaft that in turn eccentrically mounts a plurality of elongate follower arms. Each follower ann is mounted at one end to the shaft with the other end having at least one tooth configured to engage the circumferentially disposed teeth. The housing further includes a base plate that is rigidly attached to the second shaft. Rotary motion is transferred between the first shaft and a second rotatable member by apparatus that includes a base pin that is rigidly attached to the base plate, an arm pin rigidly attached to a follower ann and a linking ann pivotally attached at opposite ends to the base pin and the arm pin. The second rotatable member may be a second shaft, the housing, or the base plate.

Abstract: There is provided by the present invention a mechanical drive system for driving first and second screw conveyors from a single power source. This system includes a primary drive providing power to the first conveyor from the power source and a secondary drive that includes a pair of gear boxes and that supplies power to the second conveyor from the primary drive.

Abstract: A solid state semiconductor power switch for controlling the application of AC power to a load wherein the power switch employs momentary ON/OFF switches for activating the power switch, and wherein additional circuit means is provided to preserve the ON/OFF condition or state of the power switch during a power-down situation such that upon restoration of the AC power the power switch can be caused to assume the same ON or OFF state it was in just prior to the power-down situation.

Abstract: An apparatus for supportably elevating and lowering material handling apparatus having an elongate member includes two arms radiating upwardly from a base. A lower undercarriage arm is pivotably attached to the elongate member, and the lift arm is attached to a roller support which moves along a rail on the elongate member. The roller support and attached lift arm arm moved by a winch-drawn cable. At least one pair of spaced support sheaves is mounted on the elongate member, and the cable passes under the sheaves. At least one riser post extends upwardly from the base and is attached to the lower undercarriage arm so that it intersects the cable between the spaced support sheaves. A sheave mounted on the riser arm intersects and supports the cable when the elongate member is lowered. As the elongate member is lowered, the riser post supports an increasing portion of the downward load.

Abstract: An apparatus for collecting and transporting particulate material from directly underneath the discharge outlet of a vehicle includes a collection chamber for receiving the particulate material. An auger is provided to convey particulate material from the collection chamber to an auger chamber for subsequent discharge of the particulate material into a receiving hopper. An extension mechanism is provided which permits telescopic extension of the collection chamber and auger chamber so that the collection chamber may be placed directly underneath the discharge outlet of the vehicle. A vertical positioning mechanism is also provided which allows the collection chamber to be raised from a lowered position to closely abut the discharge outlet of the vehicle. A swivel base mount is further provided so that the collection chamber and auger chamber may be selectively rotated between a position generally parallel to the vehicle and a collecting position under the vehicle.

Abstract: A centrifugal separator for grain and like particulate material utilizing a rotatably driven separator bowl having an outwardly inclined peripheral wall, in combination with a vibrator. Vibration and centrifugal force acting on material deposited in the rotating bowl cause it to move outwardly towards the bowl periphery and up the aforesaid inclined wall for selective discharge of relatively heavy and light particles at vertically spaced exit zones formed by a guide baffle assembly adjacent the upper periphery of the inclined wall.
