Abstract: Security scanning devices based on electrical tomography, including tomography systems based on the measurement of capacitance (ECT) and electromagnetic tomography (EMT), in combination with knowledge-based image analysis and understanding. Each device includes a sensing head or transducer, sensing electronics, image reconstruction and image analysis microprocessor (either microcontroller, DSP, laptop or desktop PC), a display unit and accompanying software for identifying dangerous materials and items. The security scanning devices enable enhancement of image resolution with ECT and EMT. More sensors, more sensitive circuits and flexible/optimal measurement protocols may be employed for obtaining more independent measurements and enable implementation of data fusion to combine the complementary sensitivity of ECT and EMT to different material properties, while providing architecture to implement image knowledge bases, which may characterize objects, whose image attributes are acquired from multiple sensors.

Abstract: A method of filling and closing a bag comprising the steps of:
delivering an air jet for opening a bag;
moving a pair of horns into the open bag for engaging inner surfaces of the bag;
filling the bag;
moving a bag transfer mechanism having spaced pinch belts into engagement with the outer surface of the bag;
rotating the pinch belts for removing the filled bag from the bagger; and
moving the bag transfer mechanism from a first position adjacent the bagger to a second position adjacent a bag closing apparatus.
Abstract: A closure for an electric cable splice includes first and second generally rectangular shell segments having side walls and end walls constructed and arranged to be telescopically secured together. A threaded fastener is connectable to extend through the first and second shell segments and is adapted to urge the shell segments together with sufficient force to extrude sealant in the first and second shell segments through entrance openings to encapsulate ends of spliced cables to provide a moistureproof seal between the spliced cables and the end wall adjacent the entrance openings.
Abstract: A nonmetallic container adapted for use as a tool or utility box in a pickup truck which is preferably unitarily constructed of linear high-density polyethylene and is adapted to fit both standard and compact pickup trucks.
Abstract: A tube coupling comprising a first and second tubular member the first tubular member having a bell end and the second tubular member having a pin end for telescopic engagement within the bell end of the first tubular member. A deformable band secures the first and second tubular members in telescopic engagement and prevents relative movement therebetween. Each tubular member is provided with an annular ridge. These ridges are juxtaposed when the first and second tubular members are telescopically engaged. A deformable band having a longitudinal groove formed therein has a connector loop at one end; and a projection extending outwardly from the opposite end. The band is detachably securable around the telescopically engaged tubular members. The connector loop and projection of the deformable band cooperate to tightly secure the band around the telescopically engaged tubular members, trapping the annular ridges within a longitudinal groove, for preventing relative movement of the tubular member.
Abstract: A fiberglass pipe joint construction having threaded pin and box ends thereon. Tapered threaded portions are provided with profiles to improve alignment and sealing and prevent galling of the resinous material.
Abstract: A protective tendon tensioning anchor assembly comprising an anchor plate, a sealing cup and a resilient sealing ring for providing corrosion protection for exposed portions of a tendon secured in the tendon tensioning anchor assembly.

Abstract: A medical investigative system in which a person interacts with the system to interject information that is utilized by the system to establish non-restricted environmental modeling of the realities of surrogate conditions to be encountered with invasive or semi-invasive procedures. This is accomplished by video display of simulated internal conditions that appear life-like, as well as by display of monitor data including, for example, blood pressure, respiration, heart beat rate and the like.
Abstract: A swab for a shotgun having a cylindrical shaped disposable cleaning element removably mounted on a spindle. The cleaning element is made from a resilient closed cell polyethylene foam material having sufficient rigidity to dislodge contaminants from said bore, yet resilient enough not to score said bore. The element is mounted on a spindle with shoulders on the ends of the spindle to retain and compress the element at the ends.
Abstract: A valve comprising a valve body (10) having inlet (14 ) and outlet (18) passages communicating with a valve chamber (15). A valve element (90) is movable through the valve chamber adjacent a valve seat (92) and a flow deflector ring (104) having a central opening which has discontinuous deflector surfaces (106) around a central opening separated by spaced grooves (108) arranger to disrupt flow a stream of fluid flowing between the valve element and the valve seat to prevent the formation of a vena contracta downstream from the valve seat. A plurality of sleeves (34,36) having cylindrical walls divide the valve chamber to form an entrance section (15a) and an outlet section (15b).
Abstract: A comfortable backpacking harness including a plurality of flexible shoulder straps connected end to end by buckles to form an endless belt and a plurality of adjustable length article engaging loops permanently connected to the shoulder strap assembly. The shoulder straps and article engaging loops connected together in a manner to form a weight supporting quadrilateral on the back of the wearer whereby loads of any shape or weight can be carried by the harness.
Abstract: In accordance with the present invention, a constant flow rate control valve is provided including a cup member disposed in the flow passage through the valve. The cup member has a port located in an end wall of the cup member and a plurality of ports in the sidewall of the cup member. The cup member is movable axially within the valve, with such movement being opposed by a resilient spring member downstream of the cup member. A fixed shear ring in the valve body surrounding the sidewall of the cup member blocks or exposes areas of the sidewall ports in response to movement of the cup member. Fluid pressure acting on the end wall of the cup member urges the cup member against the spring, so that the shear member exposes only that sidewall port area appropriate to the pressure being exerted. The sidewall ports have non-identical shapes and areas, with one or more longer sidewall ports extending further toward the end wall of the cup member than the other, shorter sidewall ports.
Abstract: Impingement heating or cooling apparatus that employs an axial flow fan, a plenum, collector and a columnating assembly for directing jets of a temperature controlled gas against the surface of a food product. Means for contacting a first layer of food products with impinging jets of a temperature controlled gas and for simultaneously contacting a second layer of food products with an alternating, convective flow of a temperature controlled gas is also provided.

Abstract: Disclosed is a valve trim design for use in reducing valve cavitation. Valve and seat are axially movable and have frustoconical facing surfaces which form an annulus therebetween to control flow. The seat has an external frustoconical surface and a plurality of pairs of ports communicating with an internal bore. The ports are aligned so that flow from the ports impinge upon each other within the interior chamber of the valve seat to reduce cavitation.
Abstract: An improved mechanism for cushioning shocks imparted to a stationary body from various sizes of vessels, including a resiliently retarded telescoping member having a first movement versus thrust characteristic with a relatively high rate of movement versus thrust over a first predetermined range of thrusts, and an abruptly lower rate of movement versus thrust for thrusts exceeding said first predetermined range.
