Abstract: Disclosed is a tune-producing feeding utensil, such as a spoon or a fork. In the case of a spoon, the spoon mainly includes a metal bowl portion, a plastic handle portion, and a metal back cover. The handle portion is provided with compartments for receiving a circuit board and two serially connected button cells, as well as a shallow groove around the compartments for receiving a gasket. When the back cover is fitted onto the handle portion, the circuit board and button cells are sealed in the handle portion and the gasket is tightly pressed against the shallow groove to make the handle portion watertight. When a baby uses the spoon to feed itself with one hand holding the handle portion at the back cover and its mouth contacting with the bowl portion, an integrated circuit on the circuit board is actuated to cause a tune-producing device attached to the back cover to send out music or voice. The music or voice is helpful in encouraging the baby to enjoy feeding itself concentratively.

Abstract: A trimming shears for sheets and strips having two shears frames arranged opposite one another and on supports and being rotatable about a central vertical axis. A pair of vertically stacked adjustable roll blades are mounted in each shears frame at diagonally opposite horizontal corners of the shears frames. The roll blade pairs are rotary driven by gears and couplings to cut the sheet or strip edges. The roll blade pairs are adjustable both vertically and horizontally to accommodate different material thicknesses and widths. The roll blade pairs are arranged in the shears frames such that when the shears frames rotate 180.degree. about the central vertical axis, the position of the roll blade pairs is transposed--with the first roll blade pair taking the position of the second roll blade pair.

Abstract: This invention pertains to apparatus and methods for breaking a web along spaced lines of weakness. The invention includes a compact breaker bar assembly comprising at least one breaker bar in a gap. The apparatus also includes driving apparatus to power the breaker bar assembly in breaking the web. In some embodiments, one or more breaker bars engage and stress the web along a single transverse line across the web, breaking the web. In other embodiments, at least first and second breaker bars engage and stress the web along spaced first and second transverse lines across the web. The breaker bars can be mounted on one or more rotary elements, or can be mounted on one or more belts or other breaker bar carriers, traversing closed-loop paths.

Abstract: A workpiece-supporting fence has a pair of movable fences movably attached to a fixed fence which is secured to a base of the device in which the fence is being used. The pair of movable fences are located on opposite sides of a working tool such as a saw blade. A fixed clamping arrangement is associated with each movable fence and provides a single point actuation member for each movable fence to clamp the movable fence to the fixed fence such that the movable fence is vertically aligned and flush with the fixed fence. In one embodiment, each movable fence is provided with a gap-filling flap which is pivotably secured to the movable fence to be movable between a lower and an upper position. In its lower position, the gap-filling flap minimizes the gap between the movable fence and the working tool. In its upper position, the gap-filling flap provides additional support when working with taller or thicker workpieces.

Abstract: A process and apparatus for cutting up an element used in the construction of a nuclear installation for dismantling. The element is placed on a support and pushed toward a shearing tool having a blade pitch angle of 30.degree.. As the element is pushed, the blade performs a first shearing operation. Then a releasing stop controlled by a jack releases the element from the blade. Operation continues until the element is cut up.

Abstract: The present invention provides a bale slicer that processes large forage bales into a form useable by TMR mixing systems. The bale slicer is simple to operate, reduces the power required to process a bale as compared to other bale processors and processes forage bales into a size suitable for use as feed. The bale slicer includes a main frame, bale chamber, platforms, a cutting mechanism, and power mechanism. The bale slicer utilizes a slicing motion by the cutting mechanism to process the large forage bales. The forage bale to be processed remains stationary and is held in its compressed form by the bale chamber during slicing. The cutting mechanism passes by the bale chamber in order to slice the bale. At the end of each slice made by the cutting mechanism, the forage falls to the floor and the bale drops down in the bale chamber in preparation for the return pass by the cutting mechanism. The fallen forage is then ready to be transported to a TMR mixer.

Abstract: A chain saw guide bar includes outer side surfaces, a longitudinal groove having side walls, and two edge surfaces. Each edge surface interconnects a side wall and an outer side surface to form therewith inner and outer corners, respectively. To edge-harden the guide bar, the edge surfaces, inner corners, and outer corners are heated above 750.degree. C. Then, the edge surfaces and inner corners are rapidly cooled, i.e, quenched, but the outer side surfaces are cooled more slowly, whereby the inner corners are given a higher hardness than the outer corners.

Abstract: In an apparatus for shearing multi-walled workpieces, such as metal framing studs, a pair of base supports are spaced relative to each other to define a blade gap therebetween, and a guillotine-like blade is slidably received within the gap for shearing the workpieces. A pair of first supports, each defining a plurality of first support surfaces, are each slidably mounted on a respective base support. A pair of second supports, each defining a plurality of second support surfaces, are also each slidably mounted on a respective base support, and the second supports are spaced apart from and face the first supports to thereby define an adjustable-width channel therebetween. Each of the first, second and base supports defines a blade-like edge located adjacent to and defining the blade gap.

Abstract: A method and apparatus for determining a workpiece's surface position. One embodiment of the invention includes two conductive bodies that are insulated from each other. During a surface position determining operation, one of these bodies has a first potential, while the other body has a second potential. These bodies are then moved towards a conductive surface of the workpiece, until both of these bodies are electrically detected to contact the surface. Finally, the distance that one of these bodies traverses is used to identify the position of the surface of the workpiece.

A rear roller may be mounted behind the cutter device for dispensing a chemical composition onto the skin of the user.

Abstract: A cutting system for removing at least one section from a workpiece. The cutting system includes a frame that supports a first saw assembly for cutting at one end of the workpiece and a second assembly for cutting at the other end of the workpiece. The first saw assembly supports a stop having an up position (non-cutting position) or a down position (cutting position). For measurement purposes, the one end of the uncut workpiece is placed next to the stop in the non-cutting position and during the cutting operation the stop moves below the workpiece. The cutting system also includes a first clamp connected to the first saw assembly and a second clamp connected to the second saw assembly or the frame. The first and second clamps have either an opened position or closed position. The workpiece is secured when the first and second clamps are in the closed position. The closed position also enables the operation of the first and second saw assemblies.

Abstract: A pizza cutter with a dull convex cutting blade and a handle having two upwardly tilting ends. The non-cutting edge of the blade is fixed into a downwardly extending portion of the handle member. One end of the handle member includes a substantially oval opening for accommodating the fingers and the opposite end of the handle member has a straight handle. Each handle has a plurality of finger receiving indentations, adapted to receive the index, middle, ring, little finger, and/or thumb of a user. In use, the hands assume their respective positions at the opposite ends of the handle. The hands are alternately moved in a rocking motion while applying a downward pressure on each handle, to cut a pizza. By requiring the placement of each hand on a specific portion of the handle member, a user's fingers will not be inadvertently placed under the blade and injured.
