The front side is attached to one edge of the top at an acute angle relative to the bottom surface of the top. The compressible pad is attached to the bottom surface of the top. The compressible pad preferably has a releasable adhesive. Flexible molded-in minor protrusions may be used as the compressible pad.

Abstract: A probe for measuring fluid velocity through a conduit has a pitot tube connected to a multiple channel cylindrical tube which is placed within a tubular housing. Drive motors are provided to permit precise rotation and longitudinal movement of the cylindrical tube and attached pitot tube in the conduit, typically a stack or duct. At least one differential pressure gauge is connected to the cylindrical. A computer directs movement of the cylindrical tube, receives differential pressure and static pressure readings from the differential pressure gauge and utilizes that data to calculate flow of the fluid through the conduit. The device is particularly useful for measuring stack gas flow which flow can be utilized to determine emissions of pollutants.

Abstract: A closure for sealing punctures in blood vessels utilizes a sheet adapted to conform to the inner surface of a blood vessel which sheet has a plurality of barbs attached to one surface. A pusher rod connects to the barbed surface. The sheet is pushed through a sheath that has been inserted into the puncture until the sheet is within the blood vessel. Then, the pusher rod pulls the sheet against the blood vessel inner wall to anchor it over the puncture. The pusher rod is then released from the sheet and both the sheath and pusher rod are removed completing the closure.

Abstract: A window blind for use between double panes of glass which has an aperture in one pane of glass. The blind can be raised, lowered and tilted while maintaining the window seal. The blind includes a headrail, slats, a hollow screw with longitudinal screw channels. The hollow screw passes a headrail aperture and a glass aperture from inside the headrail to outside thus being threaded into a screw duct. At least one lift cord and a tilt control cord separately pass through the longitudinal screw channels thereby providing an external way to control the window blind.

Abstract: A multiple layer suction holder is disclosed in which a lower attaching layer is made of a soft, flexible material having a neck extending therefrom. A shell is fitted on top of the lower attaching layer where the shell is made from a flexible material which is harder than the soft, flexible material of the lower attaching layer. The suction holder is further provided with connecting devices which force the shell against the lower attaching layer in order to provide an internal pressure in the lower attaching layer directed toward the mounting surface. Hence, air cannot readily pass under the lower attaching layer. The multiple layer suction holder provides maximum contact with the mounting surface and maximum memory that results in longer life of the suction holder.

Abstract: An iron-based, corrosion-resistant, precipitation strengthened, martensitic steel essentially free of delta ferrite for use at high temperatures has a nominal composition of 0.05-0.1 C, 8-12 Cr, 1-5 Co, 0.5-2.0 Ni, 0.41-1.0 Mo, 0.1-0.5 Ti, and the balance iron. This steel is different from other corrosion-resistant martensitic steels because its microstructure consists of a uniform dispersion of fine particles, which are very closely spaced, and which do not coarsen at high temperatures. Thus at high temperatures this steel combines the excellent creep strength of dispersion-strengthened steels, with the ease of fabricability afforded by precipitation hardenable steels.

Abstract: A gas sampling system utilizing a pair of parallel sonic orifices. One of the orifices is connected to a source of filtered, heated samples. The second, larger orifice is connected to a source of dilution gas. A vacuum pump maintains a substantial vacuum behind the orifices, thus assuring critical flow therethrough. The sample and diffusion gas are mixed behind the orifices and transported under partial vacuum for analysis. The dew point of the sample is affected by both the ratio of the diameter of orifices and the degree of vacuum transporting the gas mixture. As such, the dew point can be varied indefinitely by any reasonable combination of orifice ratio and vacuum pump strength.

Abstract: A smart structure or an electronic package is formed by thermal spraying utilizing a plurality of masks positioned and removed over a work surface in accordance with a predetermined sequence. The masks correspond to cross sections normal to a centerline through the structure. Masks are placed above a work surface and sprayed with either at least one primary material to form at least one electronic component and a complementary material. In this manner, layers of material form a block of deposition material and complementary material. Then, the complementary material which serves as a support structure during forming may be removed.

Abstract: A cord lock and release system for use in a window blind assembly. The system has a stationary member and a movable member. The movable member is positioned so that at least one lift cord can move across a portion of the movable member when the movable member is in an open position. The lift cords will be restrained by frictional contact with the movable and stationary members when the movable member is in a locked position. The movable member is biased towards a locked position. A release linkage is attached to the movable member so that when a force is applied to the linkage the movable member is moved toward the open position.

Abstract: A process for stabilizing sludge containing flyash and calcium sulfate formed by a lime or limestone scrubber increases the sludge particles to a size at which leaching of toxic metals from the particles no longer occurs at toxic levels. The sludge is dewatered and injected into the furnace in a manner to cause the flyash to soften and stick together. The agglomerated particles then fall into a bottom ash pit for removal as a common waste.

Abstract: A conduit extends from a platform or a fixed structure above a deep cavity filled with deep liquid which contains dissolved gases. Sufficient liquid is drawn from the top of the conduit to cause gas containing deep liquid to enter the lower end of the conduit and release dissolved gas thereby forming a foam which causes the bulk density of the foam to fall. The change in bulk density causes the foam to move upward through the conduit pushing the foam to higher heights in an effort to reach pressure equilibrium inside and outside the conduit at a level of incipient foaming. The energy of the moving foam is used to drive a turbine or otherwise provide useful energy.

Abstract: An apparatus and method to improve pulverizer operation and reduce nitrogen oxide emissions from furnaces which burn pulverized coal from at least one pulverizer. A duct type burner burns a fuel in the primary air which heats the primary air supplied to the pulverizers. The combustion increases the primary air temperature and improves the drying of the coal, thus improving the pulverizer throughput and/or the fineness of the pulverized coal. Operation of the duct burner also reduces the oxygen in the primary air. The reduction in oxygen reduces the propensity of the coal to ignite in the pulverizers and cause fires or even explosions. The reduced oxygen in the primary air also reduces NO.sub.x formation.

Abstract: A device for closing or connecting blood vessels has a plurality of micro miniature barb which pierce the wall of the blood vessel and anchor the device in place. In one embodiment the fastener is comprised of a male member and a female member which are fastened to blood vessel segments with the micro miniature barbs. The male and female members are joined together by inserting the male member into the female member to form a permanent coupling. The device can also be used for opening a blood vessel which has been narrowed by disease or trauma.

Abstract: A combustible fuel containing 3% to 45% of the fuel needed to operate a gas turbine is introduced into the compressor air stream for the gas turbine. The mixed fuel and air stream is introduced to the gas turbine prior to the combustor stage through a pipe, orifice or nozzle. The mixed air and fuel stream serves to reduce the nitrogen oxide emissions of the gas turbine. Waste air streams such as mine ventilation air may be used as the mixed fuel and air stream.
