Abstract: An apparatus and method for connecting a residential water line to a household appliance, solenoid controlled, inlet water valve such as that used on a refrigerator freezer icemaker is disclosed. A residential water line, typically a 0.25 inch (0.635 cm) diameter copper or plastic line, is connected to an all plastic inlet connector. The inlet connector has an integral ferrule seat. A ferrule nut designed to cooperate with the ferrule seat is slipped over the water line. The water line is positioned against a shoulder in the inlet connector that properly positions the water line.

Abstract: A flow control device for a solder wave apparatus that includes an outlet or nozzle from which molten solder flows in an upward direction to contact the lower surface of a target, such as a circuit board. The flow control device provides a screen and baffle that control the flow pattern of molten solder to the nozzle so as to result in a near-parallel solder wave above the nozzle. The screen includes a pair of spaced-apart parallel panels that are disposed upstream of the nozzle. Each of the panels has apertures through which the molten solder flows before entering the nozzle. The apertures of the panels are offset from each other, such that none of the apertures are coaxial but instead overlap each other when superimposed. The baffle is disposed further upstream of the screen, and includes a number of fins disposed substantially perpendicular to the panels. The fins are arranged such that their lengths become progressively shorter in a direction away from the center of the baffle.

Abstract: A cached synchronous dynamic random access memory (cached SDRAM) device having a multi-bank architecture includes a synchronous dynamic random access memory (SDRAM) bank including a row decoder coupled to a memory bank array for selecting a row of data in the memory bank array, sense amplifiers coupled to the memory bank array via bit lines for latching the row of data selected by the row decoder, and a synchronous column select means for selecting a desired column of the row of data. A randomly addressable row register stores a row of data latched by the sense amplifiers. A select logic gating means, disposed between the sense amplifiers and the row register, selectively gates the row of data present on the bit lines to the row register in accordance to particular synchronous memory operations of the cached SDRAM being performed. Data to be input into the cached SDRAM during a Write operation is received by the sense amplifiers and written into the memory bank array.

Abstract: An address decode circuit for receiving address input signals, includes a device for detecting a change in the address input signals, and a device for generating a control signal in response to a detected change in the address input signals. A gating mechanism gates at least one address bit in the address input signals input to the address decode circuit with the control signal.

Abstract: Disclosed is an architecture of a RAM (random access memory) with BIST (built-in self test) or functional test function. The RAM has a memory cell for storing differential or single-ended binary data and bit line signals are fully differential or single-ended. Shadow write is applied to read only and read-write bit lines. With the test function, port-to-port bit line shorts and port-to-port word line shorts are sensitized.

Abstract: A light beam line projecting device having a combination of two or more lenses which magnify in only one dimension; i.e., cylindrical and plano-cylindrical lenses, which are arranged so that the lenses' physical proximity to one another can be manipulated in order to dictate the angle of light emitted from the lens system. The axes of curvature of the respective lenses are maintained in the same plane by a lens holder comprising a stationary lens holder which houses one of the lenses, a sliding lens holder which houses the other lens, and a rotating adjustment ring which provides both the outside housing for the system and the means of adjustment of the proximity of the lenses relative to each other. The sliding lens holder has projections that slide longitudinally in grooves in the stationary lens holder and projection that slide circumferentially in grooves in the rotating adjustment ring.

Abstract: A heat shield for providing thermal insulation is made of several uniform thickness aluminum sheets. Each sheet has stand-offs formed therein to space adjacent sheets and create air pockets in the heat shield.

Abstract: An apparatus and method for connecting a residential water line to a household appliance, solenoid controlled, inlet water valve such as that used on a refrigerator freezer icemaker is disclosed. A residential water line, typically a 0.25 inch (0.635 cm) diameter copper or plastic line, is connected to an all plastic inlet connector. The inlet connector has an integral O-ring seat. A gripper nut that is designed to cooperate with an O-ring and the O-ring seat is slipped over the water line. The water line is positioned against a shoulder in the inlet connector that properly positions the water line. The gripper nut is tightened to compress the O-ring, and seal and fix the water line in the inlet connector.

Abstract: A cleaning material designed for removing difficult stains and dirt from smooth and textured surfaces. The material is made of a plurality of flat chisellike synthetic fibers which are somewhat pliant and protrude from a backing designed to hold the fibers in place. The material may be embodied in the shape of a mitt to fit over the hand of the user with a backing suitable to protect the user's hands. The material may also be configured in other fashions and in combination with different backings and attached to various instruments to provide greater ease of use for particular cleaning chores.

Abstract: A cup member adapted for resting on a base of a lamp and for being sandwiched between the base and a bulb fixture threaded on a stem which passes through an aperture in the cup member. The cup member has a rim with slots formed therein to define flexible fingers which can frictionally receive the lower edge of a chimney. The cup member has integral bushings for removably receiving respective rods connected to a ring member adapted for supporting the outer shade of the lamp.

Abstract: Compounds of the formula ##STR1## where N IS 0, 1, OR 2;Q is chlorine or bromine;X is fluorine, chlorine, bromine, or cyano;Y is hydrogen, fluorine, or chlorine; andV is hydrogen, fluorine, chlorine or alkoxy of 1 to 3 carbon atoms.

Abstract: A process for preparing a thermoplastic randomly branched aromatic polycarbonate which process comprises reacting at least 20 weight percent of a stoichiometric quantity of a carbonate precursor with a mixture of a dihydric phenol and at least 0.05 mole percent of a polyfunctional aromatic compound in a medium of water and a solvent for the polycarbonate having present therein at least 1.2 mole percent of a polymerization catalyst, while concomitantly adding to the reaction medium sufficient alkali metal hydroxide to maintain a pH range of about 3.0 to about 6.0, and then adding sufficient alkali metal hydroxide to raise the pH to at least about 9.0 to less than about 12 while reacting the remaining carbonate precursor.

Abstract: A method of removing gallium from tin, lead or tin-lead alloy in which the molten metal containing gallium is treated with a molten flux of alkali metal hydroxide, alkali metal carbonate or a mixture of such constituents where the alkali metal is lithium, sodium, potassium or a mixture of these. Preferably the metal and flux are stirred together, then separated, and the flux dissolved in water and gallium recovered from the solution by electrolysis.
