Abstract: Flexible mosaic tiles and methods for manufacturing same are disclosed. A mold cavity of a mold element may have a cavity floor, a facing edge, perimeter wall surfaces extending therebetween, and a cavity volume. A layer of gel medium may be applied to the perimeter wall surfaces and allowed to dry. A volume of pouring medium is poured into the mold cavity. A volume of one or more fluid pigments is inserted into the mold cavity. The volume of pouring medium and the volume of fluid pigment are blended together. The blended volumes are allowed to set for a setting period. The blended volumes cure for a curing period in a curing environment, thereby forming a mosaic tile. The mosaic tile is removed from the mold cavity. A peel-and-stick backing may be applied to the rear of the mosaic tile for facilitating attachment of the mosaic tile to a substrate.

Abstract: A portable hand cart particularly suited for carrying a welding system is provided. The cart includes a bottom platform carried by a rectangular bottom frame; a back frame extending upward from the bottom frame and including an angled handle; a top platform carried by a rectangular top frame that is somewhat narrower than the bottom frame; a front frame extending upward from the front sides of the bottom frame; two front wheels; two back pneumatic wheels; a lower tank frame extending rearward from the back bottom frame and supporting a tank platform; and an upper tank cradle extending rearward from the back of the top frame. The cart is stable and balanced both in a shop and in the field when loaded with a welding system and with or without a compressed gas cylinder.

Abstract: A multi-purpose maintenance machine having interchangeable units to perform different maintenance functions such as: lawn mowing; lawn aerating; dethatching; lawn seeding and/or fertilizing; salt spreading; and snow blowing/throwing. The machine has a frame on four wheels and an exchangeable maintenance component has arms which are slidably received in slots. Different maintenance components perform different maintenance functions. A drive shaft is inserted in an axial bore of the component to engage the component and a sun gear so that rotates the component. The sun gear is rotated by an electric motor.
