Abstract: A fitness rig includes a plurality of vertically extending posts arranged in at least one or a plurality of pairs of post disposed in perpendicular and parallel arranged vertical planes. A horizontally extending bar is vertically positionable on certain of the pairs of vertical posts. A connector complimentary to the shape of the vertical posts is mounted on each opposite end of the bar. A plurality of spaced apertures are formed in the vertical posts and the connectors and receive a pin to vertically adjustably position the connectors and the horizontally extending bar in a vertical plane along one pair of the vertical posts.

Abstract: A dipper assembly includes a dipper, a dipper door, a closure mechanism, and one or more block assemblies. The dipper door is pivotally mounted to the dipper, and has a closed position in which the dipper door covers the dipper bottom. The closure mechanism has a locked position and an unlocked position, and is coupled to the dipper back and the dipper door. In the locked position, the closure mechanism holds the dipper door in the closed position. In the unlocked position, the closure mechanism allows the dipper door to swing away from the closed position. The block assemblies are coupled to the dipper back and limit a rotation of the side link plate to a pre-defined angle that corresponds to the closed position.

Abstract: A dipper assembly includes a dipper, a dipper door, a closure mechanism, a trip assembly, and a camshaft support assembly. The dipper door is pivotally mounted to the dipper for movement between an open position and a closed position in which the dipper door covers the dipper bottom. The closure mechanism is configured to retain the dipper door in the closed position. The trip assembly is configured to release the dipper door for movement to the open position, and includes a trip arm coupled to a camshaft and also coupled to a trip rope. The camshaft support assembly is configured to receive the camshaft, and includes a bearing block receiving a rotatable bearing member, and a sealing mechanism.

Abstract: A dipper assembly includes a dipper, a dipper door, and a closure mechanism. The dipper door is coupled to the dipper, and has a closed position in which the dipper door covers the dipper bottom. The closure mechanism has a first position and a second position. In the first position the closure mechanism is configured to permit movement of the dipper door away from the dipper bottom. In the second position, the closure mechanism is configured to retain the dipper door in the closed position. The closure mechanism includes a link having a first leg and a second leg, one or more side link plates coupled to the link and to the dipper back, and a closure mechanism pin assembly configured to adjust the position of the link relative to the dipper door.

Abstract: Apparatus for supporting the components of an air conditioner unit having an indoor section and an outdoor section, each of which contain a heat exchanger and a fan. A base pan is provided to support the components of the unit and an auxiliary pan is mounted inside the base pan beneath the indoor fan and the indoor heat exchanger. A shroud surrounds the indoor fan that contains a scroll for directing conditioned air into a horizontally disposed passage that distributes the air uniformly across the unit. The auxiliary pan contains a trough that forms part of the scroll. Both the shroud and the auxiliary pan are cast from light-weight styrene.

Abstract: An image projection device includes a Fresnel lens positioned in an optical path of an illuminated image in such a way that light from the image passes twice through the Fresnel lens, once in each direction. The first optical element may be a planar mirror arranged to reflect light transmitted by said Fresnel lens in the first direction back through said Fresnel lens in the second direction. In addition, a second optical element may be provided for changing a path of light exiting said Fresnel lens in said second direction so that the projected image appears at a location away from the path of light from the image source to the Fresnel lens.

Abstract: The base pan of a packaged terminal air conditioning system has a first condensate collecting surface under its evaporator coil and a second condensate collecting surface under its condenser coil. Fluid communication between the two surfaces is provided by a condensate flow channel, and the second condensate collecting surface is disposed at a lower vertical height than said first condensate collecting surface, such that the condensate which forms on the evaporator coil drops off and immediately flows to the second condensation collecting surface. A lifting wall is placed just upstream of a lower portion of the condenser fan and adjacent the second condensate collecting surface. The lifting wall, in cooperation with the fan creates an area of decreasing pressure above the second condensate collection surface so as to draw up the condensate into a radially inward portion of the fan where it is drawn into the fan and dispersed onto the condenser coil.
