Abstract: An adder (300) generates encoded outputs to conserve power. In particular, the adder provides "B2" encoded outputs which only drive one bit per every two bits at a time on conductive lines in a data processing system. A binary input is encoded by an encoder (800, 304) to generate a plurality of bits. The plurality of bits are concatenated to form a plurality of sum values. A portion of the plurality of sum values are then selectively output in response to a logic value of a carry kill signal, a carry generate signal, and a carry propagate signal.

Abstract: Elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like. Novel elastomer composites are produced. Such novel elastomer composites may be cured or uncured, and combine material properties, such as choice of filler, elastomer, level of filler loading, and macro-dispersion, not previously achieved.

Abstract: A demolition shear is attachable to a mobile machine by one of two brackets. The brackets engage, alternatively, two of three pairs of mounting holes on the shear so the shear can be mounted at its proximal end to the stick or at its side to the boom of the machine.

Abstract: The invention relates to a mixing apparatus for maintaining a pressure differential over varying feed rates by mixing a flow of sludge with a flocculant. The mixing apparatus includes a monitor for monitoring the pressure differential across the apparatus and a device for varying the size of an orifice in the apparatus through the sludge flows. The orifice size is dependent on the monitored pressure differential to maintain a desired differential pressure over a range of sludge feed rates.

Abstract: Elastomeric compositions are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture flowing continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Semi-confined flow of the mixture in the coagulum zone is achieved preferably with progressively increasing cross-sectional dimension of the coagulum zone from the mixing zone to the discharge end. Highly efficient and effective elastomer coagulation can be achieved without the need for a coagulation step involving exposure to acid or salt solution or the like.

Abstract: The present invention concerns a method of protecting plants from pathogen attack through synergistic disease resistance attained by applying a conventional microbicide to immunomodulated plants. Immunomodulated plants are those in which SAR is activated and are therefore referred to as "SAR-on" plants. Immunomodulated plants may be provided in at least three different ways: by applying to plants a chemical inducer of SAR such as BTH, INA, or SA; through a selective breeding program based on constitutive expression of SAR genes and/or a disease-resistant phenotype; or by transforming plants with one or more SAR genes such as a functional form of the NIM1 gene. By concurrently applying a microbicide to an immunomodulated plant, disease resistance is unexpectedly synergistically enhanced; i.e., the level of disease resistance is greater than the expected additive levels of disease resistance.

Abstract: This invention provides novel radiopharmaceuticals that are radiolabeled cyclic compounds containing carbocyclic or heterocyclic ring systems which act as antagonists of the platelet glycoprotein IIb/IIIa complex; to methods of using said radiopharmaceuticals as imaging agents for the diagnosis of arterial and venous thrombi; to novel reagents for the preparation of said radiopharmaceuticals; and to kits comprising said reagents.

Abstract: An apparatus for impacting bone chips in a bone canal. The impactor has an impaction head of predetermined dimensions and a stem extending therefrom. There is a visual indicator provided with means for secure location on said stem to visually indicate the distance of insertion of the impaction head within a bone canal.

Abstract: A list of graphics orders defining the graphics objects to be displayed is processed to generate a list of modified graphics orders representing those portions of the graphics objects not overlaid by an overlapping area. The mechanisms for clipping to the inside of a bounded area are adapted to determine what portion of an area of graphics lies outside a bounded area. The invention includes techniques for dealing with graphics in the form of lines, areas bounded by lines, and images including arrays of picture elements or symbol set characters.

Abstract: A method of applying a starch sizing to a forming web on a paper machine, such as in the form of a curtain on a fourdrinier machine, employs a suspension of uncooked particulate starch and water which is applied, as a suspension, to the inlet of a downwardly opening die positioned over the forming web and applied at a consistency of between about 2 to 10% onto the surface of the web as a free falling curtain, the impact velocity of which is controlled to a rate sufficiently low to prevent distortion of the web on impact. Improved drainage is achieved by heating the suspension to a temperature less than about 150.degree., to prevent the cooking of the starched particles. The curtain may be applied to the web at fourdrinier table consistencies as low as about 2% and still obtain starch retention rates of about 80%.

Abstract: The NIM1 gene product is a structural homologue of the mammalian signal transduction factor I.kappa.B subclass .alpha.. The present invention exploits this discovery to provide altered forms of NIM1 that act as dominant-negative regulators of the systemic acquired resistance (SAR) signal transduction pathway. These altered forms of NIM1 confer the opposite phenotype as the nim1 mutant in plants transformed with the altered forms of NIM1; i.e., the transgenic plants exhibit constitutive SAR gene expression and a constitutive immunity (CIM) phenotype. The present invention further concerns DNA molecules encoding altered forms of the NIM1 gene, expression vectors containing such DNA molecules, and plants and plant cells transformed therewith. The invention also concerns methods of activating SAR in plants and conferring to plants a CIM phenotype and broad spectrum disease resistance by transforming the plants with DNA molecules encoding altered forms of the NIM1 gene product.

Abstract: A flexible jacket covering is pre-stretched, pre-flattened and pre-cut to predetermined length and width dimensions for attachment onto a transfer cylinder. The flexible jacket covering is marked with alignment stripes and centering marks for faster, simpler and precise attachment of the flexible jacket covering onto the transfer cylinder in an operative position. A predetermined precise amount of movement or looseness of the pre-fabricated flexible jacket covering relative to the transfer cylinder support surface is established in the operative position. Reinforcement strips are stitched onto the gripper, the tail and the operator/gear side edges of the flexible jacket covering for stabilizing the flexible jacket covering and preventing detachment from the transfer cylinder during high speed press operation. At least one side of each reinforcement strip has pressure sensitive adhesive for securing the flexible jacket covering onto the transfer cylinder.

Abstract: A communal electricity metering system supplies electricity to consumer sites via metering sites which each comprise a number of separate metering and meaurement devices, and a common control unit. The control unit stores credit data for each consumer site, and monitors the consumption of electricity at each site, interrupting the supply when the respective credit is exhausted. Display units at the consumer sites communicate with the control unit, which transmits status data to each display unit. In addition, a consumer can use the display unit to communicate with a central control station via the control circuit at the metering site, via a combination of mains-borne and radio communication, to purchase additional credits and to receive confirmation of the entering of such credits at the metering site.

Abstract: A device and method for selectively controlling the flow of production fluid through a tubing string in an oil and gas well according to which a housing is connected to a tubing string for insertion into the well, and well fluid is passed from the ground surface into the housing. The housing is provided with a plug to establish well fluid pressure in the housing to actuate a packer and/or other ancillary devices. The plug can be removed from the hosing by increasing the pressure of the well fluid in the housing above a predetermined value, thus permitting the flow of production fluid from the formation zone, through the housing and the tubing string, and to the ground surface.

Abstract: The dressing for heavily exuding wounds comprises a hydrophilic foam having an absorptive capacity of at least 10 times its own weight, such as a hydrophilic polyether polyurethane foam material derived from a foamable composition comprising a polyol component containing ethylene oxide groupings. For use on bleeding wounds and/or to improve the absorptive capacity of the foam itself, the foam may be impregnated with alginate, which acts both as a haemostat and as an absorption improver. The dressing may include a backing layer which provides a barrier to microorganisms.

Abstract: Freshly printed sheets are transferred from one printing unit to another by transfer cylinders each having an ink repellent, electrically conductive, striped flexible jacket covering that is movable relative to the sheet support surface of the transfer cylinder. The jacket covering is made of a flexible fabric material that is pre-stretched, pressed flat, cut to size and treated with an ink repellent compound and is also treated with an anti-static ionic compound or is otherwise rendered electrically conductive by one or more conductive strands. Electrostatic charges carried by the freshly printed sheets are discharged through the ink repellent, electrically conductive, flexible jacket covering into the grounded transfer cylinder. A low friction, electrically conductive cylinder base covering that includes center alignment marks is secured to the transfer cylinder for engaging the flexible jacket covering.
