Abstract: A pictorially searchable anatomical database with computer assisted mapping is presented. The pictorial portion of the database and the textual portion of the database are fully unified, i.e., all elements are “live” and visually navigating through one will instantaneously display the corresponding element of the other. A “standard reference” and unique visual keys are presented; selection of a structure of interest may be displayed both in the form of a conventional two-dimensional scan and a three-dimensional view of the structure of interest; all structures in both the 2-D and 3-D views may be interrogated. In addition, structures connected to the structure of interest may likewise be displayed in both the two- and the three-dimensional views.

Abstract: A real time soil constituent sensor and precision agricultural chemical delivery system may measure simple in situ soil constituents without the aid of externally applied solvents, or such solvents may be utilized intermittently to calibrate the measurements for greater accuracy. A real time complex in situ soil resistivity sensor and prescription agricultural chemical delivery system includes a plurality of ground-engaging tools in association with individual soil electrode arrays which measure complex solute and matrix resistivity levels. Conventional engaging tools may serve as electrodes for impressing a voltage source and serve as a current sink for the purposes of determining complex resistivity values and components thereof in in situ soils. Alternatively, local resistivity measurements in a single tool can also be employed for separation of resistivity cotributions of the soil solute and the matrix.

Abstract: First hydraulic drives (e.g. cylinders, pistons) and lift arms attached to dump truck side panels, preferably reinforced, move a trailing tag axle, and wheels supported by the tag axle, between operative and storage positions without bending the truck frame. A linkage assembly and second hydraulic drives (e.g. cylinders, pistons) coupled to the lift arms and the first hydraulic drives move the tag axle and the wheels between raised and lowered positions. In the operative positions of the lift arms and the tag axle, the wheels contact the ground and, because of the first hydraulic drive construction, move smoothly over road bumps and into road dips. In their storage position, the lift arms are disposed above and to the rear of the dump truck with the trailing tag axle and the wheels above the body but lowered to minimize their height above the truck.

Abstract: A flexible, self-supporting decoy for wild game which requires no wind to inflate and which maintains its shape even under heavy dew or rain showers. When used for birds, the decoy may comprise as few as three pieces, namely, a stake, a windsock-type body of flexible yet self-supporting material, and a fastener. The body may be rotatably supported about a stake by the simple expedient of an opening in the lower portion of the body large enough to pass over the stake and a second opening in the upper portion too small to pass over the stake but large enough to receive a fastener with a head or flange large enough to secure the body. Such decoys may be quickly collapsed for transporting or quickly unfurled for decoying, will move with wind, and are lightweight, durable and effective. Formed or molded heads may be added for additional realism.

Abstract: An ultralight yet extremely strong vessel without a circumferential support suitable for full-length, end-dumpable trailers, for railroad tank cars, highway tank trailer, refuse transportation vehicles and the like. High strength and minimum weight are achieved by arcuately stressing but light materials, by provision of longitudinal support members which may become an integral part of the vessel and, in open-top embodiments, by provision of a reinforcing member along an extended open edge of adequate horizontal moment of inertia and which may readily be pre-tensioned if desired. In the pre-tensioned embodiment, such to reinforcing member may cause the open-top vessel to bow inwardly before loading so as to compensate for the outward-tendency of such vessels constructed of elastic materials when loaded.

Abstract: A device for monitoring and collecting toxic wastes in underground reservoirs, with no moving parts, is disclosed herein. A pollutant/water separator is supported interior to an outer chamber for protection which is ventilated for communication therethrough. The lower portion of such chamber forms a collection chamber for collected toxins to which still more chambers may be added in modular fashion for greater storage capacity and increased intervals between servicing. The ventilation array is preferably arranged so as to not to permit communication until the assembled device is weighted, and to retain a buoyancy chamber above such array so as to further support such device and to exclude water from the top of the separator without any mechanical seals. By elimination of hydrocarbon-based adhesives, proper selection of materials, and the use of triply-sealing mechanical connections, all chances for the monitoring device to contaminate pure wells and to cause false positive indications are eliminated.

Abstract: Apparatus and methods are described for inhibiting the unintentional spillage of hazardous materials, particularly while changing filters or other storage media in environments such as service station fuel dispensers and other fuel depots. A preferred embodiment includes mechanisms for permanently attaching such apparatus and securing the same against unintended rotational or translational displacement, as well as collecting and diverting mechanisms and mechanisms to inhibit the improper removal of such filters or storage media.

Abstract: A real time soil chemical sensor and precision agricultural chemical delivery system includes a plurality of ground-engaging tools in association with individual soil sensors which measure soil chemical levels. The system includes the addition of a solvent which rapidly saturates the soil/tool interface to form a conductive solution of chemicals leached from the soil. A multivalent electrode, positioned within a multivalent frame of the ground-engaging tool, applies a voltage or impresses a current between the electrode and the tool frame. A real-time soil chemical sensor and controller senses the electrochemical reaction resulting from the application of the voltage or current to the leachate, measures it by resistivity methods, and compares it against pre-set resistivity levels for substances leached by the solvent. Still greater precision is obtained by calibrating for the secondary current impressed through solvent-less soil.

Abstract: A device and kit for cleaning generally convex surfaces of lenses of field articles such as hunting scopes, telescopes, cameras and the like.

Abstract: A self-resetting animal trap utilizing a closed-door approach wherein the trap is set or ready when its trap door is closed. The self-resetting animal trap has an enclosure with a top opening and a pivotally mounted trap door for the top opening. A metal plate is attached to the trap door frame beneath the trap door such that the trap door has an upwardly and downwardly pivoting portion. A magnet is slideably mounted to the underside of the upwardly pivoting portion such that the magnet is in contact with the metal plate when the trap door is closed. The magnet and the metal plate form the trigger mechanism for the trap. The weight of the magnet also urges the trap door toward a set-closed position from a tripped-open position, thereby resetting the trap. A bait container is positioned near the end of the downwardly pivoting portion. A chute is also provided allowing approach to the bait container only via the trap door.

Abstract: Recirculating tube cleaners pass through inside diameters in a bank of heat exchanger tubes. Variable density tube cleaners are provided which are pressurized to compress and have a substantially neutral buoyancy upon entry from an inlet manifold to the inside diameter of the tubes. Upon exiting from a heat exchanger outlet manifold, the tube cleaners return to either positive or negative buoyancy depending upon the embodiment. Skimmer means intercept tube cleaners having positive buoyancy from the upper portion of flow and direct them to a recirculation system. Open cell elastomer tube cleaners having negative buoyancy may be intercepted at the bottom of the flow and then partially dewatered for adjustment toward neutral buoyancy. As contrasted to prior art embodiments in which the entire outlet flow must be screened, here only a small percentage, for example one percent of the outlet flow, need be intercepted.

Abstract: Flow control of a shear-sensitive, i.e. pressure gradient degradable, liquid from a high pressure source to a lower pressure discharge is achieved by controlling the liquid's exposure to a degradation pressure gradient. Two displacement chambers are provided and connected by a control conduit. First and second movable barriers in the first and second chambers respectively contain a separate controlling liquid. A pressure and flow control valve is included in the control conduit. Incoming pressurized controlled shear-sensitive liquid flows into the first displacement chamber to displace the first barrier which displaces controlling liquid through the flow control valve. Shear-sensitive liquid is dispensed at relatively lower pressure from the second chamber in response to movement of the second barrier driven by the controlling fluid coming from the control conduit into the second chamber.

Abstract: In a flow rate control apparatus, pressure of a primary, or controlled, liquid is reduced without application of shear forces thereto. Each of first and second piston and cylinder assemblies has a first port on one side of the piston and a second port on the other side. A secondary fluid path between the two second ports contains a controlling fluid directed through a pressure reducing valve. The rate of flow of the primary fluid from the discharge cylinder is controlled by the rate of flow of the secondary fluid through the pressure reducing valve. A four way valve couples the controlled liquid at relatively high pressure through the first port in a first cylinder, and the controlled liquid is discharged at relatively low pressure from the first port in the second cylinder. The first and second pistons are rigidly connected to assure synchronized motion and accurate metering of the controlled liquid and to provide for driving of both pistons in response to input pressure of the controlled liquid.

Abstract: In combination with a fluid applicator of the fluid marker type, a unitary, self-sealing, one-way check valve for admission and retention of air under pressure to the interior of the applicator, an elastomeric bulb for developing pressure and means for relieving internal pressure.
