Abstract: A method and apparatus for lifting the tabs of a protective seal with edges embedded in a laminate. The base of the device has an annular top having a plurality of cartridge receiving apertures spaced equally from one another. Each hole receives a tab engagement assembly comprising a cartridge, a spring, and a finger have an abutment surface. The finger is pivotally fastened at one end within the slot of the cartridge and is biased away from the cartridge by the spring. When the base is placed in proximate relationship with the laminate seal patch secured to the substrate, the rotating base causes the abutment surfaces of the fingers to drag across the periphery of the laminate seal in a circular motion. The stresses created on the tabs of the protective seal cause the embedded edges to be lifted. The lifted tabs are accessible to the end user and the protective seals may be easily peeled from the substrate when desired by the end user.

Abstract: Comminuting media comprising a martensitic/austenitic steel which contains at least about 40 percent by volume retained austenite, a portion of which is work transformable to martensite. The steel contains sufficient alloy content such that the steel has a martensite start and finish temperature sufficiently low to allow partial transformation of austenite to martensite during quenching of the steel from the austenitic range, but leaving some retained transformable austenite. This steel is used as a comminuting media, the retained austenite transforming to martensite through working or abrasion of the comminuting media during use in a comminution process. The outermost volume of the comminuting media which forms the wear surface and which contains the retained austenite in an amount of at least 40 percent by volume comprises at least 25 percent of the total volume of the comminuting media.

Abstract: A ham product which is formed by cutting a spirally sliced half ham longitudinally through the bone. The cut can be made by feeding the half ham through a band saw blade by hand, by pushing a split cart through the blade, or by feeding the product through the blade on a split belt conveyor. A special tray for packaging of the ham product has either a flap providing a double layer of material at the location of a sharp exposed corner of the femur or a plurality of cushioning dimples extruded at appropriate location thereon to pad the femur corner.

Abstract: A motor vehicle gearbox with an infinitely variable reduction ratio comprises an input shaft, an output shaft, a first gear stage with a continuously adjustable reduction ratio, and a second gear stage in the form of a summarizing gear. The input shaft is connected to the input of the first gear stage and, via a first coupling, to a first input of the second gear stage. The output of the first gear stage is connected to a second input of the second gear stage and, via a second coupling, to the output shaft, which simultaneously forms the output of the second gear stage. The first gear stage is part of a main gear. The main gear and the second gear stage are disposed coaxially relative to each other and to a common main axis. The first gear stage takes the form of a frictional body gear, in particular a frictional wheel epicyclic gear, in which two bodies abut each other in a frictionally engaging manner in a region. The frictional bodies rotate over the entire reduction range at a higher speed (n.sub.
