  • Patent number: 6820652
    Abstract: A multi-channel valve having a valve seat, a valve seal, and valve seal housing. The assembly of the apparatus creates a plurality of inlet, exit, and cross channels enclosed by elastomeric portions of a valve seal. The elastomeric portions of the valve seal create bounded distensible chambers. Pressure exerted by a fluid in excess of the cracking pressure of the seal tends to distend portions of the elastomeric seal and allow flow through and into the chambers. When inflow pressure falls, the elastic rebound of the elastomeric portions of the seal tends to expel fluid from the valve without backflow. Cross channel capacity allows mixing of the fluids. The plurality of, and differentials between, chambers allows one fluid to completely purge the valve of other fluids. The valve may be configured with additional backflow prevention capacities, such as channel variations, secondary elastomeric members, and variations in primary membrane properties.

  • Patent number: 6715449
    Abstract: An adjustable animal collar provides a strap with a housing at one end and a second end connected to an engagement area. The engagement area is formed with a plurality of teeth received into the housing, where a rotating pawl engages the teeth. The pawl, pivotably rotating within the housing and partly covered in one embodiment with a cover plate, has a biasing means, which in one embodiment is a torsion spring, to bias the pawl in favor of engagement with at least one of the teeth. The biasing means can be overcome by manual pressure on a portion of the pawl, causing release of the collar. The collar may have at least one safety device preventing the pawl from being inadvertently disengaged, and a safety indicia area to visually indicate the locked or unlocked status of the collar. The collar is capable of attachment to a variety of accessories.

  • Patent number: 6664508
    Abstract: Deep penetration gas tungsten arc welds are achieved using titanates such as Na2Ti3O7 or K2TiO3. A small amount of the titanate is applied to the weld zone in a carrier fluid paste or as part of a wire filler to afford deep penetration welds in carbon, chrome-molybdenum, and stainless steels as well as nickel-based alloys. To control arc wander, bead consistency, and slag and surface appearance of the weldments, various additional components may be optionally added to the titanate flux including transition metal oxides such as TiO, TiO2, Cr2O3, and Fe2O3, silicon dioxide, manganese silicides, fluorides and chlorides. However, the toxicity of the plumes from halide additives and the necessity of post-weld removal to prevent corrosion may preclude their use. In addition, it was found that a flux of titanium oxides, Fe2O3 and Cr2O3 affords deep weld penetration in carbon steels and nickel-based alloys but with some heat-to-heat variation.

  • Patent number: 6659329
    Abstract: A new soldering technique and solder alloy for wetting and joining hard-to-wet materials including titanium alloys such as nitinol uses a solder alloy containing tin and an active wetting promoting element such as aluminum in the presence of ultrasound. As shown in the Figure, molten solder alloy (10) is applied to the hard-to-wet material (18) with the application of ultrasonic energy (14) which removes coatings (20) such as tenacious surface oxides to leave the base material (18) which is readily wetted by the solder alloy (20).

  • Patent number: 6608278
    Abstract: To overcome 1) the high levels of porosity due to coating material vaporization and entrapment into the weld, 2) spewing of molten base metal from the weld leaving holes and pits in the weld, and 3) humping effects when oblong beam configurations are used at higher weld speeds to weld coated materials, the present invention features an energy source (10) with multiple separated energy beams (24, 26) (formed by using multiple separate beam sources or manipulation of a single beam (14) into separated multiple energy beams (44, 46) using wedge mirror (18) and parabolic focusing mirror (20)) that produces high quality (porosity free) lap welds in a weld stack (50) of layered materials (30, 32) coated with coating material (28, 28′, 34, 34′) with zero gap at interface (38) during the welding process.

  • Patent number: 6596122
    Abstract: A method for production of simultaneous lap and butt joints directs electromagnetic radiation (12) through a radiation transmitting material (40) to an absorbing material (44a, 44b, and 44c) that absorbs radiation (12) with the generation of heat. The heat provides sufficient molten material in interfaces (50a, 50b, and 50c) to fuse and bond: 1) pipe ends (14, 24) to each other in a butt joint (22), 2) pipe end portion (16) to sleeve (40) in a lap joint (28a), and 3) pipe end portion (26) to sleeve (40) in a lap joint (28b). Use of a sufficiently clear material for sleeve (40) allows visual inspection of joints (22, 28a, and 28b). Butt joint (22) can be formed by conductive heating without absorbing material (44a) to provide a smooth interior bore useful for transporting high purity fluids without risk of absorbent contamination or debris and organism collection in gaps found in previous joining techniques.
