摘要:
A vehicle assembly system automatically decks and automatically fastens body components to chassis components. The system uses an automatic decking and fastening unit that includes a base with an elevatable platform repositionable relative to the base by at least one actuator. A slidable unit carries a fastener driver, is supported on the elevatable platform, and is repositionable relative to the elevatable platform by at least one other actuator. The slidable unit also carries an arm that is repositionable relative to the slidable unit by yet another actuator. A pair of conveyors are positioned away from the base, are movable relative to the base and carry a pair of vehicle components. The conveyors are cycled so that the vehicle components are positioned relative to one another in a predetermined position, and the actuators are operated to reposition the fastener driver to a position determined by engagement of the slidable unit with one of the vehicle components.

A compound for reducing the incidence of pseudofolliculitis combines a mild skin astringent, an oil based epidermal softener, and a hair stiffener. One embodiment of the compound combines refined powdered oatmeal and emollient of the compound combines refined powdered oatmeal and emollient oil, such as mink oil and liquid vitamin A in a petroleum jelly base. The mixture is applied by being massaged into the skin prior to lathering and then again immediately after the rinsing of the face after shaving. Continual usage significantly reduces the eruption of pseudofolliculitis.

An underreamer including a body having a bore therethrough, an arm mounted at its upper end to the body, a sleeve member detachably secured to the lower end of each arm and adapted to receive the frictional wear caused by the rotation of the conical cutter mounted thereto. Bearings and seals disposed between the cutter and the sleeve member provide smooth rotation of the cutter. In addition, locking pins and bearings extending between the arm and the sleeve member secure the sleeve on the arm. The arms are pivotally mounted in slots in the body and mechanical structure is provided for moving the arms to their cutting position with their lower ends positioned radially outward from the body.

A chemically bondable foundry sand comprising a mixture of sand, binder and a plurality of fibres intimately mixed and dispersed throughout the mixture. Cores and moulds made from such sand have improved fracture resistance. The mixture may comprise from 0.01 to 1.0 wt. % of fibres, the length/diameter ratio of each fibre may be at least 10 and the fibres may have a length of from 1 to 20 mm. The fibres may be glass fibres, organic fibres or natural fibres. The binder may comprise a silicate binder or an organic binder such as a phenolic binder or a furane binder.

A computerized automated demand-based parts delivery management system and method is disclosed. Parts for use in a production facility are received at a warehouse and housed in storage inventory areas such as trailers parked in a yard. Data about the parts in storage inventory areas and their locations as well as an inventory of parts in the warehouse are stored in a database. A “demand pegging” operation is performed by viewing current delivery inventory levels within the warehouse and applying them to production demand data to determine when parts will be depleted from delivery inventory areas. The operation further identifies storage inventory areas that have the needed parts. Process times for transporting parts between locations are considered in determining task times for transporting parts from storage inventory areas to delivery inventory areas so parts are replenished in advance of the deplete time determined by the demand pegging operation.

Processes for improving copper/iron selectivity in a solvent extraction circuit by contacting an acidic aqueous solution containing dissolved copper and iron ions with a solvent extraction composition including an orthohydroxyaryloxime, a selectivity modifier, and an equilibrium modifier, wherein the ratio of selectivity modifier to orthohydroxyaryloxime is from 0.001 to 0.05, thereby decreasing the copper:iron transfer ratio, are provided herein.
摘要:
A parts delivery management system and method that synchronizes production line side parts deliveries with a production schedule to facilitate delivering the right part to the right production line location at the right time. A consolidation center for receiving parts from suppliers is co-located with an assembly plant. Parts are received in returnable containers and organized for line side delivery according to the manufacturer's production schedule. Parts are delivered to production line locations using multi-cart “trains” that transport parts to the locations. Trains made of multiple carts are assembled throughout the production day and loaded with containers holding the parts that are then delivered line side. A delivery management system application executing on a computer receives production schedule data as well as part and container data to determine which parts are needed throughout the day at the various production line side locations and when they are needed.
摘要:
A solvent extraction composition and process for using the composition is provided. The composition contains up to 70% by weight of at least one orthohydroxyarylketoxime extractant and/or at least one orthohydroxyarylaldoximes extractant, salts and mixtures thereof; from about 0.1 to about 20% by weight of at least one substantially water insoluble aromatic hydroxy containing antidegradation agents. The composition optionally contains an equilibrium modifier.
