Abstract: A foldable cart apparatus includes a first, second and third U-shaped frames pivotally joined and functionally movable between a folded attitude and an unfolded attitude. Its primary function is for carrying articles such a beach related items. In the folded attitude the frames are positioned adjacently. In the unfolded attitude the first and second frames diverge upwardly and the second and third frames diverge downwardly as viewed from the side. The first frame is engaged with a bottom strut supported on spaced apart wheels for moving the apparatus on a surface. A flexible sling is engaged with the first and the third of the frames, so that in the unfolded attitude, a vertical rear containment wall and a horizontal bottom shelf are formed. A flexible fabric bag is fastened between the first and second of the frames and forms an open topped container for receiving the items for transport. The bottom shelf can be used to support an ice chest or other bulky article.

Abstract: A sludge digesting method uses a mixing tank providing an integral ceiling, interior wall surface and a floor surface. A vertical beam supports a mixing device engaged for movement along the vertical beam. A plurality of sparger jets protrudes from the wall surface for delivering an oxygen gas flow directly into the interior of the sludge. A second plurality of sparger jets terminates at the mixing tank floor surface for delivering oxygen gas into the mixing tank and a plurality of bubbling diffusers in a circle ⅔ of the diameter of the tank protrudes upwardly from the floor surface for delivering further oxygen gas flow into the mixing tank. The method provides for mixing and entraining oxygen into a process sludge, in an amount of between 4-45 ppm, to accelerate digestion as a batch or continuous process.

Abstract: A porting apparatus in an internal combustion engine delivers and exhausts gas in a combustion space. A pair of cylinders each have a cylinder wall mounted for rotation within a head of an engine block. The cylinders each provide a pair of apertures in diametrically opposing and axially offset positions through the wall of the cylinder. A pair of rotatable manifold rods, each axially oriented, are each positioned within one of the cylinders. The manifold rods each provide a through port adapted for alignment with the pair of apertures of a corresponding one of the cylinders, such that within each of the cylinders and corresponding through ports, a gas flow is enabled for communication from one of the pair of apertures to the other of the pair of apertures through the through port upon each full rotation of the cylinders which are driven in coordination with the engine.

Abstract: Pipelining is a well-known efficient technique for optimally designing high performance digital circuits. However, conventional pipelining techniques are difficult to pipeline the execution of a loop with variant iteration execution lengths in a circuit. The invention presents a new pipeline design approach, called dynamic pipelining, to design and pipeline this kind of loop in a circuit efficiently. Instead of assuming a fixed latency (or data initiation interval), the approach pipelines the loop using run-time determined latencies to achieve a high performance. The general controller architecture of it is also introduced. It consists of two interactive finite state machines to allow the pipeline datapath to execute at variant latencies. Experimental results show that the approach can obtain about 2 times speedup with acceptable area overhead.

Abstract: The presentation and storage folder (10) allows filing of transparencies in a normal binder (1) and in addition allows projecting these on an overhead projector (2) without detaching these from their binder. The folder is composed of at least three leaves the first of which (11) allows to file it in a classical binder, the last (13) being composed of the transparency or of a transparent pocket which can contain the transparency proper whereas the leaf or leaves in between (12) allow to unfold the folder and place the transparency on the glass of an overhead projector without needing to detach the folder from the binder.

Abstract: A remotely controlled power float apparatus comprises a horizontally oriented platform supported on a pair of spaced apart, rotationally mounted, floats. The floats each provide a downwardly directed flat surface for moving in contact with, and thereby smoothing, a non-hardened concrete surface. Mounted on the platform is a fan, rotationally adapted for directing a horizontal thrust vector in a variably selectable direction for moving and steering the apparatus over the concrete surface. The floats are adapted for being tilted thereby enabling a variable contact area between the floats and the concrete surface.

Abstract: A ballistic panel comprises a monolithic epoxy bonded plate made up of laminated individual panels integrally encased within a composite plastic outer shell. At least one of the individual panels is comprised of an integral laminated stack of individual layers of composite and metal construction. An outer layer of composite plastic is used to enclose the structure. The panel achieves high strength, light weight and low cost in construction.

Abstract: A water craft apparatus has an elongated hull with turbine propulsion drive adapted for ingesting water at a turbine water intake and for ejecting the water, with high velocity, at a turbine water outlet. A plurality of water suction apertures are arranged along both a starboard and a port portions of the hull, and these are in communication, through an intake manifold, with the turbine at the water intake for delivering the water from the body of water to the turbine. A plurality of aperture doors are hingably mounted on the hull, each one of the plurality of aperture doors is movable between an open attitude spaced outwardly from the one of the water suction apertures enabling admittance of the water into the intake manifold, and a closed attitude positioned for sealing the one of the water suction apertures. The apertures span a longitudinal distance along the hull. The longitudinal distance exceeds a horizontal length of a wave cycle of the body of water.

Abstract: A clip-on sunglasses has a pair of lenses with mounting holes. A pair of bridge clips are integrally joined at opposing ends of a bridge wire. A mounting tongue of each of the bridge clips is engaged with one of the mounting holes for securing the bridge wire to the lenses using the bridge clips. Upper mounting snaps are engaged with the bridge clips and the mounting hole. Each one of a pair of lower mounting snaps is engaged with a further one of the mounting holes in each of the lenses, the upper and lower mounting snaps each providing a hooked finger extending therefrom, the hooked fingers positioned for engagement about opposing edges of a pair of eyeglasses, enabling the lenses to be removably engaged over front surfaces of the eyeglasses.

Abstract: An inventory control and management method provides a combination mobile device for communication and for reading labels (R&C). The R&C reads an inventory label affixed to an item of inventory in the stores. A data file is created corresponding to the label reading and includes a time stamp taken at the time of the reading. The data file is imported into a computer data processor. A network of fixed distributed communication nodes (transceivers) is positioned over the inventory store for receiving temporal cyclic signature pulses from the R&C. At least three of the communication nodes are used to perform a triangulation for locating the R&C, and the location and the corresponding time is recorded. By comparing the time of a given reading of the label with a corresponding time of the triangulation, it is possible to determine where any item is located within the stores.

Abstract: I present a method for matching the spatial relationships between an input set of feature points and a template set of feature points. A feature point consists of a location in space and a label describing the feature at that location in space. A tessellation over the feature point locations is performed. Next, a search identifies polyhedra that have similar contents, the contents being the angles and labels associated with feature points of the polyhedra. Once a match is found, then appropriate adjacent and neighboring polyhedra are examined. Matching the node labels and angular relationships for a set of appropriate adjacent and neighboring polyhedra extends the volume over which matches exist and significantly increases the certainty that a positive match exists.
