An apparatus for reducing muzzle blast upon discharge of one or more projectiles from a gun includes an outer shell and a first end cap adapted to be secured to a muzzle of a weapon and including provisions for detachably coupling to a first end of the outer shell. The apparatus further includes a second end cap adapted to be secured to a distal end of the outer shell and a plurality of baffles disposed between the first end cap and the second end cap. The plurality of baffles each comprise a bore section having an inner diameter no smaller than a bore of the muzzle and a baffle section coupled to the bore section, the baffle section extending from the bore section to the outer shell.

Abstract: A method for forming a low dielectric constant insulator in a monolithic substrate and the dielectric formed by a method. The method includes formation and patterning of a mask on a silicon substrate followed by anisotropic etching of the silicon to provide a dense array of deep holes. Isotropic etching may be used to form a cavity beneath the dense array of holes and coupling to bottoms of the holes. Sides of the holes are then thermally oxidized. A conventional dielectric is then formed, sealing tops of the holes. The conventional dielectric is optionally densified. Conventional chemical-mechanical polishing then planarizes the dielectric and further conventional processing may be carried out on the wafer to form active circuitry together with passive components such as high Q inductors.

Abstract: A method of introducing sealing liquid into a tire, the tire having a valve stem, the method comprising the steps of coupling the valve stem to a sealing liquid source in liquid communication with a line, providing a peristaltic pump in the line for pulling sealing liquid through the line from the sealing liquid source and pushing the sealing liquid through the line to the tire.

Abstract: A quick connect/release wheel and hub assembly includes first and second hub portions. The first hub portion has a dovetail groove formed therein and the second hub portion has a mating dovetail ridge formed therein. The dovetail ridge is positioned to be engaged in the dovetail groove by relative transverse movement of the first and second hub portions from a non-coaxial orientation into a coaxial orientation. The engaged dovetail ridge and dovetail groove hold the first and second hub portions fixedly together in the coaxial orientation. A movable member is coupled to either the first or second hub portion and movable between a position in which the hub portions are held in the coaxial orientation and relative transverse movement is prevented, and a position in which relative transverse movement of the hub portions from the coaxial orientation into the non-coaxial orientation is allowed.

Abstract: Apparatus for preventing fluid transfer through an opening connecting an oviduct to a uterine cavity comprising an insert for insertion into the oviduct through the opening leading from the uterine cavity to the oviduct, a seal carried by the insert for engaging uterine tissue leading to the opening and receiving fibroblast ingrowth to create a hermetic seal between the oviduct and the uterine cavity, and an engagement element supported by the insert for securing the insert to the oviduct.

Abstract: A scrubber for removing pollutants from a gas comprising a housing for conducting the gas therethrough, a mechanism for introducing pollutant-reactive filtering agent into the housing, a sump for collecting the filtering agent and having a first volume, and an intermediate sump for collecting the filtering agent and channeling the filtering agent into the sump, the intermediate sump having a second volume that is less than the first volume.

Abstract: Described is a method for installing a gray water reclamation system in an existing plumbing infrastructure. A flexible conduit 26 is connected to the drain of a gray water source by moving the flexible conduit through an access 36 in the plumbing infrastructure and through the drainage conduit 41 to the drain where one end of the flexible conduit is coupled thereto. The other end of the flexible conduit is located adjacent the access and is in fluid communication with a filtration apparatus 27 and a storage vessel 28 so that the gray water may be filtered and then stored. A plumbing snake may be used to move the flexible conduit through the existing plumbing infrastructure.

Abstract: An activator for curing a gel component comprising a premixed composition of a solvent soluble with the gel component, a polymerization initiator, and a viscosity modifying agent including at least one substantially non-reactive polymer, and one or more of 0.0005 to 10 vol % toluenesulfonamide epoxy resin and 0.005 to 50 vol % N-ethyl o/p toluenesulfonamide, the premixed composition being mixed together prior to combination with the gel component.

Abstract: Apparatus for allowing wheeled passage between a first surface and a second surface separated by an obstacle, the apparatus comprising a base positionable on the first surface, and a framework having a proximal end mounted to the base and a distal end positionable on the second surface, the framework movable between a collapsed condition and an extended condition defining a substantially planar support surface between the proximal and distal ends for allowing wheeled passage between the first surface and the second surface.

Abstract: Therapeutic implantable cardiac pacing systems incorporating electrocardiographic acquisition and QRS discrimination circuitry, for the purpose of ventricular pacing during wide QRS complexes of intrinsic origin, in order to narrow the QRS complex. Resultant narrowing of the QRS complex increases coronary artery flow and electrode position is employed to improve ventricular motion in the treatment of functional ventricular abnormalities caused by wide QRS complexes.
