Abstract: A rack and pinion assembly for a steering assembly is disclosed. The rack and pinion assembly has: a housing; a rack disposed in the housing, the rack being translatable in the housing; a pinion engaging the rack for causing translation of the rack; and at least one rolling element connected to the rack. The at least one rolling element is translatable with the rack. The at least one rolling element rolls along an inner surface of the housing as the rack translates. A steering assembly having the rack and pinion assembly and a vehicle having the steering assembly are also disclosed.

Abstract: An integrated device for wastewater purification, comprising a coagulation zone; a flocculation zone connected to and in fluid communication with the coagulation zone; a flotation zone connected to and in fluid communication with the flocculation zone and comprising a froth discharge port; and a separation zone below and in fluid communication with the flotation zone and comprising a contaminant separator and a purified wastewater discharge port; the wastewater entering the device being mixed with electrolytically-generated coagulants and gas bubbles in the coagulation zone; the flocculation zone receiving and gently mixes coagulated wastewater contaminants and gas bubbles formed in the coagulation zone and aggregating them into flocs before flotation of buoyant flocs in the flotation zone and the separation zone being adapted for further floc formation, oil coalescence, settling and discharge of non-buoyant contaminants.

Abstract: The invention is directed to an apparatus for exercising a user's muscles that includes a frame. A platform is attached to the frame, which defines an area on which a user stands. A weight stack is attached to the frame. A lineal shaft is attached to the frame between the platform and the weight stack. A carriage runs on the lineal shaft and is attached to the weight stack by a cable. An extension arm is pivotally connected to the carriage. A handle is attached to the extension arm. The lineal shaft and platform allow the user to adjust the machine to their body by just standing in the position that fits their body. The lineal shaft, carriage, and pivotal connected extension arm provides a resistance curve that fits the user's strength curve.

Abstract: The refractory material applied to an electric arc furnace runner is 85 to 95 wt. percent alumina, and 5 to 15 wt. percent aqueous sodium silicate. The heat from molten metal being processed is transmitted to the refractory material of the present invention by contact of the molten metal with the refractory material or by transmission of heat to the refractory material so as to sinter at least a portion of the refractory material and form a solid barrier to the flow of molten metal through the refractory. After the molten metal has been processed and no longer contacts the refractory material, the refractory material can have a portion which is free of water and remains in the form of a powder.

Abstract: The invention is a bracket for installing a gutter cover for ducting rainwater to a rainwater gutter, where the gutter cover prevents debris from entering the gutter. The bracket is roughly shaped like three extended fingers, where each finger is a strut. The struts converge at a junction. The various struts are a lifting strut that supports the leading hooked frontal edge of a gutter cover, a stabilizing strut that has a hooked end that interlocks with the hooked edge of a frontal rim of a gutter trough, and a bracing strut that is a leg stemming from the junction to a bottom portion of the gutter.

Abstract: The invention is a gutter cap for ducting rainwater to a rainwater gutter, while simultaneously deflecting debris. The invention is particularly suitable for retrofitting pre-existing aluminum gutters. The gutter cap can be installed with minimum tools and with no disruption to the existing gutter. The gutter cap is comprised of a sloped cover, which uses the attraction of water to bend water around a hooked edge as it drains across the sloped cover and ducts it into the trough. The cover, which forms a roof over the gutter's trough, is mounted with mounting blocks that snap on the cross-struts supporting the gutter, and these mounting blocks interlocks with the hooked edge of the cover. An opposing longitudinal edge on the cover is attached to the fascia board of the roof using a few screws or nails.

Abstract: An apparatus for supporting a lamp post or the like, comprising a base frame, and at least a first support column coupled with an end to the base frame and having at its other end a first coupling member for fastening to the light post, at a position removed from the base frame, wherein a second support column is provided whose one end is coupled with the base frame and whose other end is provided with a second coupling member for fastening to the first support column, between its to extremities, such that the first coupling member of the first support column that is to be coupled to the light post, is above the base frame and, viewed from the top, between the ends of the first and a second support columns coupled to the base frame.

Abstract: Organic waste material is pneumatically transported within air and mixed rewith by swirling flow through an annular injector passage of varying radial width into a reaction flow passage of an eductor nozzle section receiving the output plume of a plasma torch for initiating therein thermal gasification of the waste mixture. The plasma torch plume projects from the eductor section into a diffuser section within which thermal gasification is continued before discharge of gasified waste.

Abstract: An automatic gain control circuit and method ensure feedback for oscillator circuitry fabricated on a single semiconductor chip to adapt to the Q value established by a resonator circuit connected to the oscillator circuitry, and to ensure that gain is maximized and linearity of operation preserved within the voltage rails of the power supply.

Abstract: Disclosed is an integrated system for continuously melting and refining secondary and blister copper to produce and continuously cast anode grade copper comprising: continuous melting of secondary and blister copper in an optional fuel vertical shaft furnace; continuously or semicontinuously skimming initial slag from the surface of the melted copper in a slag vessel as it drains from the shaft furnace; collecting a reservoir of molten copper in a holding furnace capable of controlling its temperature and subsequent flow; adding fluxes to the molten copper; directing the molten copper into an oxidation vessel where the molten copper and impurities are oxidized; transferring the oxidized and fluxed molten copper to a second slag vessel where slag is skimmed from its surface; flowing the oxygen rich molten copper into a reduction vessel where oxygen content is reduced; collecting a supply of refined molten copper in a final holding vessel; continuously passing the refined molten copper through a filtering ladle

Abstract: An improved cooling method and apparatus for a continuous casting process of the type wherein the mold is a rotatable casting wheel having a peripheral groove with a portion enclosed by an endless band. The improved cooling of the hot cast metal bar is accomplished by injecting a cooling fluid, under pressure, into the shrinkage gap between the hot continuously cast bar and the band portion of the mold after the bar is partially solidified but before it is removed from the wheel portion of the mold.
