Abstract: A single port, internal liquid heat exchange assembly for heating domestic water from a free-standing, low pressure wood fired boiler. A threaded manifold fastener retains the assembly in suspension within a single access port of a conventional water heater. An elongated manifold contains first and second coaxial flow columns which terminate at exposed inlet and outlet ports and communicate with each other within the manifold. Constructions are disclosed having concentric flow columns, convolute and expandable manifold walls, internal bypass ports, vibration dampeners, multi-ported flow transition zones and which may include a sacrificial anode.

Abstract: Modular, firearm support cradles, an assembled rack and means for securing the cradles and rack to a variety of vehicle configurations. The rack includes a longitudinal frame member and from which project multiple padded cradles. Strap fasteners and lock means respectively restrain firearms and sundry paraphernalia to the cradles and rack. A telescoping expander bar assembly and mating extension arms permit a vehicle ceiling mount and/or roll bar mount of the rack. Cradles having sleeves which mate to the expander bar assembly facilitate use tailored mountings. A clamp plate assembly and mating extension arms permit a vertical divide mount of the rack.

Abstract: A shock absorbing collar assembly mountable in projecting relation to instrumentation supported from a stand. In one construction, a resilient, annular cushion member and mating rigid cover protect the instrumentation upon stand collapse or tip over. In other constructions, tip detection means release latches secured to various caged spring and pneumatic constructions which resiliently expand to raise a second resilient collar and encase the instrument.

Abstract: A steerable compression clamp assembly includes a guide plate for aligning the assembly with an oil wellhead casing and clamp and compression assemblies for collapsing the casing to seal same. The clamp assembly provides an articulating arm which cooperates with a stop arm. The compression assembly includes a pair of crushing dies which mount to a hydraulic ram. In alternative configurations, a cable directed drag skid or a tracked vehicle support the compression assembly. Remotely mounted controls direct machine operation and steering. A hydraulic cylinder may also be included with a split duide plate to provide a controlled separation of the guide plate during compression.

Abstract: Portable tractor, trailer apparatus for shredding varieties of materials, including asphalt, concrete, wood, demolition and landfill debris. A fifth-wheel mounted trailer includes a collection hopper having a hydraulically driven end-wall which directs materials into a cutter-head. The cutter head is indirectly driven by a pair of hydraulic drive motors, transfer belts and tensioned pulleys. A pivoting floor section includes a number of spaced apart rakers determines the size of exhausted particulates. The cutter-head includes teeth which clear an axle space at each sidewall and teeth which distribute materials across the width of the head. The head is removable via sidewall channels provided in the support framework.

Abstract: A multi-section hollow sound chamber containing a plurality of beads and including bore holes or a tubular mounting bore, which is isolated from the sound chamber, for supporting the chamber from a fishing line, wire-form or lure. Associated buoyancy and rotation means facilitate auditory sounds. In various constructions, the chamber parts mount in mated and bonded relation about a hook shank, a wire-form coupling member or a fishing line. Included fins or external grooves facilitate chamber rotation with movement relative to water.

Abstract: A small aperture horn antenna comprising an outer conical shell and interiorly of which are formed at least first and second conically flared, dielectric-coated stages of differing flare angles which are coupled to one another via an intermediate cylindrical stage. The dielectric coating is applied to form a uniformly smooth horn interior surface. Mountable to the antenna input aperture are various reflective and homogeneous dielectric refractive focusing lenses and to the output is a low noise waveguide converter. A remotely controlled, axial mount assembly enclosed in a gas-filled, roof mountable radome is also disclosed. Alternatively, the same antenna geometry may be used to transmit a directive electromagnetic wave.

Abstract: Fish bite signaling apparatus having a base shaped to cover an ice hole and including a hinged vertical handle which supports a fish line containing reel. A spring biased signaling flap projects from the base, magnetically interconnects with a number of magnets mounted to the reel and cooperates with separate visual and audio annunciation means. Line tensioning means and accessory support means are also provided.

Abstract: A multi-sided tray including means for pivotally supporting a plurality of coin display holders. Winged projections from each holder align with slots which include an entry/exit portion and a pivot portion. Transverse longitudinal slots receive notched slide rails which align with the holder slots and whereby individual holders may be released or locked to the tray relative to a keyed lock engages a slide actuation means.

Abstract: A collapsible seating assembly including a support platform whereon a rifle, camera or the like may be rigidly supported. A multi-legged base rotatively supports a triangular framework stanchion and to which a height adjustable seat is separately mounted. When constructed as a shooting assembly, the platform supports an adjustable, clamp mounted V-shaped barrel support or other sighting mechanisms.

Abstract: A windup holder mountable to a collapsible container for progressively ejecting stored contents from a spout and storing the spent container. A key member having a slotted body and a winged end mount in rotatively supported relation to a slotted, C-shaped support bracket. In an alternative embodiment, the key is rotatable in a single direction via annular geared portions of the body which mate with projections from the winged end of the key.

Abstract: A self-directed seating support and posture control assembly operable between fully seated and erect posture positions. A hand operated, hydraulic lift mechanism pivotally supports a cushioned seat and folding linkage from a base framework. A forward positioned upright utility platform includes a heighth and tilt adjustable tabletop. Depth controllable, cushioned knee/calf and mid-section supports extend from the platform uprights. An accessory, upper body exerciser detachably mounts to the chair back at pivotally mounted arm rests.

Abstract: A method and apparatus for parallel processing "live" and pre-recorded "reference" fingerprint data for comparison purposes. An array sensor images a selected portion of a live fingerprint and video means produce corresponding digital live image data. The pre-recorded, multi-pixel reference data and the image data are scanned relative to one another via recirculating First-in-First-Out (FIFO) buffer memories and row and column shift means. Exclusive OR (XOR), summation and accumulation circuitry simultaneously compare the reference and image data over a plurality of correlation cycles and compute a correlation value for each correlation cycle. A microprocessor determines the best correlation value of the reference and image data from a tabular store of correlation values for each correlation cycle relative to a PASS/FAIL threshold.

Abstract: Bottle mounted liquid metering apparatus including a helical fastener band self-adapting to a thread pitch. In alternative embodiments, collars rotatively supported relative to a pour tube and a plug portion control the size of a vent aperture and/or a fill window within the interior of the bottle along the pour tube and thereby the volume dispensed; a bottle vent integrally extends from the body of a threaded cap or a plug in radial relation thereto; and electronically timed annunciator means sequentially, uniformly meter a dispensed volume.
