Abstract: A drag bit mold fabricated from high temperature resisting material is machined to accept cylindrically shaped polycrystalline diamond cutters (PCD) having tungsten carbide bodies. Each of the multiple PCD matrix pockets in the mold is formed by two independent non-parallel end mill passes. The first end mill cut defines the PCD cutter position in the cutting face of the matrix diamond drag bit. The second end mill cut superimposed over the first end mill pocket creates a surrounding pocket which fills with powder metallurgy matrix material to provide support for the cylindrical cutter. The second end mill is only slightly larger than the first end mill to minimize the size of the insert securing fillet subsequently formed thus assuring that the fillet will not interfere with the depth of penetration of each of the PCD cutters.

Abstract: A process for separating liquid hydrocarbons from a wastewater using acoustic energy below cavitation is disclosed. The wastewater containing the residual hydrocarbons is introduced into a vessel which has at least two groups of acoustic transducers attached to it. Acoustic energy is applied to the fluid at an intensity below cavitation level and sufficient to induce at least one standing wave in the fluid. The liquid hydrocarbons are allowed to coalesce within the vessel to a coalesced droplet size of about 20 microns. These coalesced hydrocarbons are then separated from the wastewater.

Abstract: A quantum interference device in the form of a variable lateral confinement resonant tunneling transistor having a quantum waveguide structure including a primary current transmission path defined by a region between source and drain electrodes and where there is a resonance region therebetween in which quantum interference of tunneling wave functions establish a resonance tunneling condition that extends beyond the primary current path. Upon the application of a voltage across the drain and source electrodes, a tunneling current can be made to flow. A gate electrode formed on the quantum well structure remote from the primary current transmission path includes a variable depletion region thereunder or an electrostatic pinch off region, the size of which is a function of the magnitude of the bias voltage applied thereto.

Abstract: A compact transmitting and receiving antenna has dual feeds permitting magnetic and electric dipole radiation. The antenna includes a loop antenna disposed within a loop shield and a mast. The loop shield is insulated from ground and a feed is provided to it and the mast to excite these as an electric monopole. The shield becomes part of the monopole antenna and provides the benefits of top-loading. An isolation transformer permits the simultaneous transmission of monopole and dipole radiation. The transformer converts an unbalanced coaxial feed line to the balanced loop antenna and isolates the monopole feed voltage from the loop antenna feed. To eliminate the affect of the monopole feed on the loop feed, and vice versa, the components on the high side of the monopole feed (the loop shield and mast) are driven in common mode (voltage) by the monopole feed, and will not couple the loop antenna feed through the transformer windings.

Abstract: Mine tailings and similar materials are disposed of by replacing the tailings in underground mineworks including the shafts, adits and drifts by forming a slurry of tailings using dredging or similar mixing processes and pumping the slurry to the mineworks. Cementitious materials may be added to selected quantities of the tailings slurries to form cement plugs for placement at selected intervals in the mineworks to minimize connectivity of the mineworks shafting, adits and drifts. The mineworks may be dewatered to provide a source of water for the slurrification process and the water may be reused after separation from the slurry. The disposal process provides a convenient way of replacing mine tailings in a repository of similar mineralogy and at least partially eradicates abandoned mineworks, including shafting, adits and drifts, which otherwise might require continual monitoring and dewatering.

Abstract: A dispensable, disposable reversible forearm protector is made up from continuous webs of composite material. Each of two laminated webs, comprised of a layer of soft, absorbent paper toweling or the like and a moisture impermeable layer of thermoplastic or similar material, is arranged face-to-face with the other and joined by heat sealing or other means along generally transverse strip-like bonding areas of the web to form rectangular or trapezoidal segments of the web. Lines of weakness running along the strip-like bonding areas allow successive segments to be detached from the web. Each segment forms a flat, tubular element, which is expandable to circular form so as to receive the hand and forearm of a user. Preferably, the bonding areas are angled so that the individual segments are of trapezoidal shape, providing a tapered tubular configuration for better conformance with the contours of the forearm.

Abstract: For lifting, supporting, or carrying a child, a garment composed of material with sufficient strength to support the child's weight independently, or by incorporating reinforced seams, or by an integrated harness. The garment includes a handle that is securely fastened thereto to enable an adult to raise the child from the floor and carry the child with minimum discomfort and safety. The handle is typically attached to a portion of the garment which is reinforced in some fashion so that the stress on the child is distributed throughout the garment to minimize focusing a force on any one area of the anatomy. The handle can be readily gripped by an adult and will typically be found on the back of the garment. The handle portion may be aligned either horizontally or vertically. The garment, in connection with the handle, is configured so as not to injure the child while permitting maximum support for carrying the child by gripping the handle.
