Abstract: A disposable dental wipe made of a material substrate of predetermined size and dimensions for use in wiping the teeth, gums, and oral mucosa of an infant is provided. The dental wipes are impregnated with fluoride to strengthen erupted and growing teeth. Use of the dental wipes depends upon sensory pressure nerve endings in the user's fingers to quantitate the pressure at the time of cleaning. Fluoride may be impregnated onto the wipe for introduction into the oral cavity through any suitable composition, including gels, pastes, and powders, but is preferably introduced through an aqueous solution. Also included is a dental wipe dispenser for storing the wipes for ready usage.

Abstract: A portable ambulatory therapy device provides for the training or retraining of persons in developing walking skills after suffering a serious illness, injury, or other infirmity which limits their walking skills. The present device comprises a folding walkway with opposed folding hand rails along each side thereof. The hand rails are supported by a series of telescoping upright columns or posts, with the columns being pivotally secured to the walkway at their lower ends and pivotally secured to the hand rails at their upper ends. Each column includes a single locking pin which selectively locks the column in the upright position as desired, or allows the column to fold when removed. When the locking pins are removed, the walkway may be lifted at its center section to cause the two ends to fold together, along with the hand rails which fold to lie adjacent the walkway.

Abstract: A reciprocating stacker for relatively narrow, thin, and flexible continuous strip material provides for the stacking of such material in evenly distributed layers on a pallet or the like. The machine includes a distribution or feeder head which receives the strip material from a conveyor and distributes it evenly on the pallet. The head reciprocates or oscillates in a first direction to lay the material out in a zig-zag or accordion fold configuration, while simultaneously translating in a second direction normal to the first direction, to distribute the material evenly laterally across the surface. When a complete layer has been formed, the machine turns the pallet by ninety degrees so the orientation of the next layer is normal to the orientation of the immediately underlying layer. The process continues, with the feeder head being raised to maintain a substantially constant distance between the head and the underlying surface, until the stack is completed.
