  • Publication number: 20050090578
    Abstract: This invention relates to a heat-cured furan foundry binder system comprising a furan binder and a furan monomer or oligomer containing at least two terminal hydroxymethyl groups. The binders are particularly useful as warm-box binders, because they cure faster and foundry shapes (typically cores and molds) made with the binders exhibit higher tensile strengths than those made with conventional heat-cured furan binders.

  • Publication number: 20050030426
    Abstract: A method and an apparatus of displaying component video signals. Firstly, a component video signal is received, and a vertical synchronous signal and a horizontal synchronous signal are separated from the component video signal. Thereafter, the format of the component video signal is determined by analyzing the vertical synchronous signal and the horizontal synchronous signal, and a video processing route corresponding to the format of the component video signal is chosen to generate visual output from the component video signal. Thus the visual output is displayed.

  • Patent number: 6809600
    Abstract: Dual loop phase lock loops having a high loop bandwidth with low power consumption are described. Each loop is provided with a voltage supply regulator circuit which regulates the voltage of a portion of each loop. In one embodiment, the outer loop employs a regulation circuit comprising a two stage operational amplifier which is compensated by a compensation circuit that is configured to ensure that the dominant pole of the operational amplifier is associated with the first stage of the operational amplifier.

  • Publication number: 20030162709
    Abstract: This invention relates to multi-specific, multivalent binding proteins and methods of generating these agents from VH and VL domains. The binding protein has three or more binding sites where at least one binding site binds with a hapten moiety and at least two sites bind with target antigens. The present invention further relates to bispecific, trivalent heterodimers that have at least one binding site with affinity towards molecules containing a histamine-succinyl-glycyl (HSG) moiety and at least two binding sites with affinity towards carcinoembryonic antigen (CEA), and to trispecific, trivalent heterodimers that have at least one binding site with affinity towards molecules containing a HSG moiety, at least one binding sites with affinity towards CEA, and at least one binding site having affinity towards a metal-chelate complex indium-DTPA. Moreover, this invention relates to recombinant vectors useful for the expression of these functional heterodimers in a suitable host.

  • Publication number: 20030148409
    Abstract: The present invention relates to multivalent, monospecific binding proteins. These binding proteins comprise two or more binding sites, where each binding site specifically binds to the same type of target cell, and preferably with the same antigen on such a target cell. The present invention further relates to compositions of monospecific diabodies, triabodies, and tetrabodies, and to recombinant vectors useful for the expression of these functional binding proteins in a microbial host. Also provided are methods of using invention compositions in the treatment and/or diagnosis of tumors.

  • Publication number: 20030113333
    Abstract: This invention relates to a kit containing a multivalent, multi-specific binding protein and a carrier molecule. The binding protein has two or more binding sites where at least one binding site binds with a hapten moiety and at least one site binds with a target antigen. The carrier molecule contains a linking molecule that bears a diagnostic agent and/or a therapeutic agent and two or more haptens. The present invention further relates to bispecific diabodies that bind with hapten moieties and target antigens and to recombinant vectors useful for the expression of these-functional diabodies in a microbial host.

  • Publication number: 20020194518
    Abstract: A clock generator generates a first clock signal and a second clock signal such that the timing of the first and second clock signals is adjustable. A phase detector is coupled to receive the first and second clock signals and generate a skip signal by integrating the first clock signal over one half of a clock cycle. The skip signal indicates whether the first clock signal is ahead of the second clock signal. The first and second clock signals are calibrated individually. The skip signal generated by the phase detector indicates whether a load pulse should be sampled.
