Abstract: A metal cutting band saw blade has a plurality of cutting teeth defining a cutting direction, and a repeating tooth pattern of between 3 and 7 teeth. Each tooth defines a laterally-extending upper surface having a width and a height with respect to the back edge of the blade, and side surfaces extending laterally and downwardly on opposite sides of the upper surface relative to each other at acute angles relative to the upper surface. The teeth located rearwardly of the first tooth with respect to the cutting direction of the saw blade define progressively lower heights and progressively smaller acute angles of the side surfaces, and the widths of the upper surfaces of these teeth are greater than the width of the upper surface of the respective first tooth.

Abstract: A thermally loaded component has at least one cooling passage for the flow of a cooling fluid passing through it. In the region of a bend, at least one diverter device for the integral capturing of the flow of the cooling fluid is provided within the cooling passage. The diverter device comprises, over the height of the cooling passage, two diverter parts which are spaced apart from one another.

Abstract: A sheet metal hole cutter has a cap plate defining a substantially circular peripheral groove and an annular shelf extending radially outwardly from the peripheral groove. An elongated band forming an approximately circular shape with opposite ends of the band contacting each other defines a base edge received within the circular peripheral groove in an abutting relationship with an inner edge of the groove. The band defines an axial depth of about ½ of an inch or less, and an outer diameter within the range of about {fraction (9/16)} of an inch through about 6 inches. A weld region fixedly secures the base edge of the band to the cap plate. The annular shelf of the cap plate extends radially outwardly from the base edge of the band and defines a radial depth of at least approximately {fraction (1/16)} of an inch in order to prevent over-feeding of the hole cutter through a work piece.

Abstract: A duplex fiber optic splice has a fiber-receiving element, two clamping elements covering opposite faces of the fiber-receiving element, and a spring element. A bearing key may be inserted into a bearing channel in the fiber-receiving element and rotated resulting in resilient disengagement of each of said clamping faces from said fiber-receiving element face. The resilient disengagement of the clamping elements are independent of each other. The splice assembly may be used alone or in conjunction with an array ferrule, pre-terminated with a fiber stub, and a housing to provide an adhesiveless field terminable connector.

Abstract: The arrangements according to the invention and the method according to the invention serve to cool platforms in turbomachines. To this end, in two platforms 210, 210′ arranged directly next to one another and having a separating gap 211 running between the platforms, at least one cooling passage 230 is arranged along the separating gap 211. In this case, the cooling passage 230 runs approximately parallel to the surface of the platforms 210, 210′. The cooling passage 230 is preferably designed as a slit-like recess in at least one side wall adjacent to the separating gap 211. If blades 220, 220′ are arranged on the platforms 210, 210′, the cooling passage 230 expediently runs approximately centrally between the blades. In addition, the cooling passage 230 preferably has a course similar to the course of the blade profile.

Abstract: A hot-gas stream (40) flows along the surface of a segment arrangement for shroud bands, in particular in a gas turbine. The segment arrangement comprises segments (20, 20′) arranged next to one another and in each case separated from one another by a gap (12). The hot-gas stream (40), in at least one section (70) of the gap (12), has a velocity component perpendicular to the direction of the gap from a first segment (20) to a second segment (20′). In this case, in said section (70), along that edge (26) of the first segment (20) which faces the gap (12), at least one film-cooling bore (52) connects a cooling-air chamber (50), allocated to the first segment, to the surface (22) subjected to the hot-gas stream (40), and/or, in said section (70), along that edge (26′) of the second segment (20′) which faces the gap (12), at least one edge-cooling bore (56) connects a cooling-air chamber (50′), allocated to the second segment, to the inside (28′) of the gap (12).

Abstract: A fiber optic splice assembly comprising: (a) a fiber-receiving element having opposite faces, first and second ends, and first and second sides, each the face having at least one elongate fiber channel and an elongate bearing channel, (b) two clamping elements, each the clamping element having a clamping face and an opposite spring face, first and second sides, the clamping elements covering at least a portion of each elongate fiber and bearing channel, and (c) a splice spring for imparting opposing normal forces on the spring faces of the clamping elements and along the first side of the fiber-receiving element, the spring permitting independent resilient disengagement of each the clamping faces from the fiber-receiving element face.

Abstract: Platform cooling having a guide-blade platform (30; 60) which is subjected to a hot-gas stream (20) and is separated by a gap (36; 66) from a combustion-chamber segment (40; 70) arranged upstream, one or more segment cooling bores (42; 72) being made in the combustion-chamber segment (40; 70), which segment cooling bores (42; 72) connect a cooling-air chamber (44; 74) to the gap (36; 66). The guide-blade platform (30; 60) has a surface (34; 64) on the downstream side in the region of the gap (36; 66), the axes of the one or more segment cooling bores (42; 72) running roughly tangentially to said surface (34; 64).

Abstract: A peristaltic pump for precision metering of small quantities of fluid through a plurality of flow lines has a plurality of flexible liquid transfer tubes disposed between a set of tube rollers and an arcuate backing plate. The tube rollers are mounted on a roller support which is rotated about a central axis and causes the tube rollers to roll successively along the tubes, compressing the tubes against the arcuate surface of the backing plate and causing the fluid contained within the tubes to flow progressively in the direction of roller movement. The tube rollers are individually gear driven and turn at a rate which provides a roller surface speed equal to the rate of movement along the tubes, thereby eliminating any frictional drag along the tubes. The flexible tubes are mounted on the pump housing under uniform controlled tension to assure that each tube dispenses fluid at an equal rate.
