Abstract: A tool for performing cuts of controlled depth in orange rinds and the like for aiding in peeling same comprises a knife (28) with a side-cutting sharpened edge and fence means (30, 66) for limiting the depth of cut which can be made by said knife. The fence can be an integral member joined to the knife by a bend (26) or it can be a pair of side members which are adjustable in position from the edge. The width of the knife with an integral fence may be tapered so that various thicknesses of rinds can be accommodated. The integral fence can have a tongue (36) for aiding in peeling the rind. The knife can have a peeling slot (38) for apples or the like. The integral fence can have a sharpened forward edge (34) for making forward cuts, parallel to a cutting board (54).

Abstract: A device in which a displaced member will automatically return to its rest position after a delay comprises a container partially filled with a viscous fluid. The container is mounted so that it can be moved between a first, stable (rest) position and a second, semistable position in which the fluid will flow slowly away from its rest position. When the fluid has moved away from its rest position sufficiently, it will cause the center of gravity of the container to shift to one side of a pivot, whereupon the container will make an automatically delayed return to its first position. The container is employed as a box lid which will close automatically a predetermined time after being opened so that it can be used as an interval timer and/or a scent release mechanism. The container is also mounted in a human novelty figure in such a manner that if it is tipped over it will return automatically to an upright position after a predetermined delay.
