Abstract: Ultraviolet (UV) radiation in the UV-C and UV-B bands, which is particularly dangerous, is absorbed and filtered by quartz glass doped with between 0.065% and 3.25%, and preferably between 0.065% and 1.3% by weight, of cerium metal, or cerium as such. Preferably, the cerium is added to quartz sand and/or rock crystal, in form of a fine-grained powder of up to 2 0 .mu.m grain size, in form of cerium aluminate (CeAlO.sub.3), present in up to about 5% by weight, and preferably up to about 2%, and melted together in a single step. The quartz glass so obtained is particularly suitable for a metal halide discharge lamp, e.g. as an outer envelope (1), or as the discharge vessel (27) itself, or for halogen incandescent lamps, to form the quartz-glass light bulb or an envelope therefor. A small quantity of titanium oxide, up to about 0.05%, may be added as a further doping agent to the melt to further improve the UV absorption in the B and C bands.

Abstract: To entertain fans at sporting events, such as baseball, basketball backboards, palm trees, hockey and soccer goals are provided as targets for fans to participate by tossing objects at the target. Targets are strapped to a person moving through the stands. In one configuration the target is attached to a backpack and raised over the head using a telescoping mechanism attached between the target and the backpack worn by the operator. In another configuration the target is attached to a helmet worn by the person working the crowd. Both the helmet and backpack arrangement use mounting brackets for attachment of the target members. To telescope the target overhead from the backpack, concentric tubes are extended from within each other using a pulley and cable system controlled by the operator.

Abstract: The present invention relates to a method for annealing metal parts, in particular sheets, in an annealing chamber of an industrial furnace under a protective-gas atmosphere, wherein the annealing comprises a heating phase, a soaking phase and a cooling phase. The annealing chamber is purged during the heating phase with hydrogen or gas rich in hydrogen until the protective gas predominantly contains hydrogen. According to the present invention a purging with an inert gas is performed towards the end of the heating phase to reduce the percentage of hydrogen in the protective gas so that the formation of carbon-containing breakdown products is largely avoided. This prevents the formation of annealing edges during the soaking phase. Towards the end of the soaking phase, a purging with hydrogen or gas rich in hydrogen is performed until the protective gas predominantly contains hydrogen and carbon-containing deposits can be removed.

Abstract: The present invention is for a two piece balloon protector (5) which consists of an cylindrical tube (10) and an inner elastomeric member (15). The inner elastomeric member (15) has a outer diameter that is smaller than the inner diameter of cylindrical tube (10) and fits inside of the cylindrical tube (10). The proximal end of the inner elastomeric member (15) has a return flange (30) that fits around the proximal end of cylindrical tube (10). To install the balloon protector (5) over the dilatation catheter balloon (20), cylindrical tube (10) is held fixed while the inner elastomeric member (15) is pulled longitudinally at its distal end, thus stretching the material, decreasing the longitudinal cross-section and creating a larger inner diameter in inner elastomeric member (15).
