Abstract: A tax stamp perforator and notcher applies a diagonal line of spaced apart perforations on a tax stamp for subsequent application to a cigarette pack. The stamp is glued or otherwise applied to the cigarette pack normally across the back of the pack and one of the sides thereof. When the cigarette pack is opened the tax stamp is torn along the line of perforations. In order to facilitate rapid application of tax stamps to a production line of cigarette packs, notches in the form of lines of increased densification are applied to each stamp in the area where the stamp is bent around the side of the cigarette pack. These lines of increased densification are arranged parallel to the edge of the cigarette pack, and preferably one of the lines lies along the edge of the cigarette pack to thereby reduce the ability of the tax stamp to spring back away from the pack when glued to the pack. This feature enables the stamps to be applied to the packs at high production rates.

Abstract: An apparatus for applying perforations to wood surfaces is disclosed. The apparatus includes a drum having interspaced incisor rings mounted thereto and a plurality of cleaning members for removing wood residues from the incisor ring teeth. Each cleaning member projects into a space between adjacent incisor rings and is irrotatably secured to the mounting platform of the apparatus. The rotation of the incisor rings relative to the fixed positioning of the cleaning members brings the side surfaces of the teeth into progressive engagement with the adjoining side surfaces of cleaning members creating a scissor action across the teeth surfaces which effectively removes wood residues from the teeth. The apparatus provides for the removal of wood residue away from the spacer rings located in the space between adjacent incisor rings using cleaning members having tapered projections for directing such residue into pockets defined therein.

Abstract: Apparatus for treating meat comprises introducing pieces of meat into a tumbling drum rotatable about a horizontal axis and which contains circumferentially spaced rods on the inside of the drum adjacent to its periphery and parallel to the axis of rotation. The rods contain teeth so that upon rotation of the drum the meat is tumbled causing the teeth to produce a mass of small cuts in the surface of the meat. The drum is sealed by a watertight door that is readily opened and closed, as needed. The tumbling process takes approximately 20 minutes. The tumbling in combination with the formation of small cuts in the surface of the meat increases the exposure of myosin protein at the meat surface and also improves color uniformity and dispersion of pickling solution in the meat.

Abstract: A wood incisor for perforating the surfaces of a rectangularly cross-sectioned elongate board preparatory to preservative treatment is comprised of sets of paired horizontal and vertical drums arranged in a manner to provide a rectangular passageway of adjustable height and width for passing various sized boards, with each drum having a plurality of outwardly protruding cutting teeth. Each set of drums includes a fixed drum which is driven, and an idler drum which is slideable with respect to its associated fixed drum by actuation of positioning hydraulic cylinders to provide the adjustability of the passageway therebetween. Each of the positioning hydraulic cylinders is joined end-to-end with a cushioning hydraulic cylinder which is connected hydraulically to an accumulator tank containing pressurized hydraulic fluid and air. Thus the position of each idler drum relative to its associated fixed drum is responsive to the lateral force imparted to that set of drums by the board passing therebetween.
