Abstract: A portable tool box having an open-top, box-like housing containing removable slats with apertures for holding tools in an upright position and a drawer slidably engaged within a drawer aperture in one wall of the housing. The drawer outer wall has an outwardly projecting shelf and a lip extending above the shelf. A cover disposed over the housing has an endwall which covers the lip for retaining the drawer in the housing. Preferably, the shelf extends around the perimeter of the housing for supporting bottom edge of one or more of the walls of the cover. The tool box cover is sturdy enough to be used as a stool.

Abstract: An Article support system comprising: a mechanism defining at least one structural support elongated channel; a mechanism defining at least one support bracket with a pivotable end insertable into the channel; a mechanism defining a latch member for latching and unlatching the bracket into and out of locking frictional engagement with the channel; a mechanism for pivotably mounting the latch from the bracket in a longitudinal and latitudinal direction; a mechanism for locking the latch to the bracket in a stressed arrangement in the latching position; a fulcrum mechanism for transmitting a first latch stress to the bracket end in the latching position and an opposing latch stress distributed among the fulcrum, and discrete areas of the latch and the bracket, the mechanism constructed and arranged for applying primary frictional force between a bracket end inserted in the channel and an interior surface of the channel in the locked position and a secondary frictional force between the bracket and latch in the

Abstract: Audio power amplifier and other related amplifiers (e.g., radio frequency control amplifiers) with means responsive to output power stage VI product to continuously adjust power supply voltage level via a negative feedback signal inversely proportional to VI product, with nonlinearity at upper limit approach and stabilize VI product or dissipation, adjust to varying load impedance, and to allow lower rated power supply components for a given amplifier task compared to prior art approaches.

Abstract: A method for enhancing steam drive recovery of oil from an oil zone disposed below an overburden (18) including injecting a surfactant continuously into a supply (20) of driving steam to uniformly mix the surfactant with the steam and thereby provide a driving fluid. The driving fluid is then introduced into the oil zone (16) under sufficient pressure to cause the fluid to drive through a flow channel (S) between the interface I and the overburden (18) thereabove. The surfactant reacts with the oil to enable the fluid to strip away a top layer of the oil which is driven to a production well 14 for removal thereof.

Abstract: An improved carburetted internal combustion engine (10) which operates with an extremely lean mixture, without a conventional cooling system, and at an elevated temperature characteristic of an adiabatic engine. The engine uses two ignition sources (20, 21) symmetrically disposed about the center of the cylinder head, and/or a third igniting and microwave coupling means (19) at the center, to achieve extreme lean mixture combustion and relatively fast burn necessary for adiabatic engine operation. The engine incorporates other features to improve its efficiency and emissions, including engine air-throttling through controlled intake valve closure and unconventional valve timing.

Abstract: An improved direct fired power system generating and employing a combustion gas which includes carbon dioxide or a working fluid including a combustion chamber (20) for burning a mixture which includes oxygen, carbonaceous fuel and recycled carbon dioxide working fluid at a first pressure of above 1100 PSI thereby providing a combustion gas which includes carbon dioxide and water at substantially the first pressure and above 31.degree. C. A first turbine (16) allows the gas to expand therethrough to generate power and reduce the combustion gas pressure to a second pressure below 1100 PSI while maintaining gas temperature above 31.degree. C. A second burner (20) heats the combustion gas to a higher temperature and a second turbine (21) allows the gas to expand therethrough to generate power and reduce the pressure to a third pressure while maintaining gas temperature above 31.degree. C. A heat exchanger (26) includes ducts (28), (30) in heat exchange relationship.

Abstract: The apparatus consists of a plurality of piston pumps having preset displacement ratios. A motor mechanism is connected to each of the pumps. In addition, there is a control mechanism connected to each pump ensuring that all pistons execute their previous stroke completely before being reversed and that they all start their following stroke at exactly the same moment. Furthermore there is another control mechanism controlling the speed of each piston so that all pistons complete their respective strokes simultaneously. A mechanism for adjusting and varying the pump displacement is also provided.

Abstract: A shock absorbent shoe sole (10) including an upper sole (14) and a bottom sole (12) attached to the bottom of the upper sole, the bottom sole including one or more inverted cups (22, and 24) disposed therein; each cup is located directly beneath and pointed convexly toward a natural contact point (60, 62, 64) of the human foot (54) for absorbing and dispersing shock generated at the natural contact point during a foot step.

Abstract: Pumping in oil wells and like power conversion applications is carried out in an economical manner with efficient utilization of energy and low capital cost by pushing or pulling the plunger mechanism (of conventional type) with a metal wire, rod or tube arranged as a helical coil spring and constructed of a material that exhibits shape memory effect. This is accomplished by cyclically first straining the helical coil by loading it with a mechanical load and thus causing a structural transformation or martensitic transformation in the material and then upon the application of heat thereto (by electrical self heating or an external heater in proximity thereto), reversing the transformation to contract in material length with a fractional multiplier effect on contraction in length of the helical coil to raise the plunger, the coil having an expanded to compressed length ratio of 2:1 or substantially greater.

Abstract: Method of heavy oil recovery from deep formations using in-situ wet oxidation steam generation, and a generator for such purpose, comprising a feed for a coal/water slurry and a feed of oxidative gas from ground level to the formation, forming a cavity in the formation where the slurry and gas meet for "wet oxidation" under the inherent pressures and temperature of the deep cavity, augmented by pressurizing the feeds and, if necessary by use of a primary ignitor, to generate carbon dioxide and steam which forces the heavy oil through one or more producing regions located in the formation in the neighborhood of the cavity. Packing may be set in place above the formation to limit escape of productive gas products of the wet oxidation.
