Abstract: A reactor for plating a metal onto a surface of a workpiece is set forth. The reactor comprises a reactor bowl including an electroplating solution disposed therein and an anode disposed in the reactor bowl in contact with the electroplating solution. A contact assembly is spaced from the anode within the reactor bowl. The contact assembly includes a plurality of contacts disposed to contact a peripheral edge of the surface of the workpiece to provide electroplating power to the surface of the workpiece. The contacts execute a wiping action against the surface of the workpiece as the workpiece is brought into engagement therewith The contact assembly also including a barrier disposed interior of the plurality of contacts. The barrier includes a member disposed to engage the surface of the workpiece to assist in isolating the plurality of contacts from the electroplating solution.

Abstract: The present invention relates to an improved blast cleaning apparatus for cleaning coiled wire with abrasive cleaning material. A prior art apparatus for blast cleaning wires comprises an elongated boom provided with annular splitters for longitudinal separation of wire coils and metal lifters for radial separation of wire coils to expose substantially all of the surface of the wires to the abrasive cleaning material. Due to the hardness of the lifters, some abrasive cleaning material becomes embedded in the wire and causes problems with subsequent processing steps. The present invention provides a blast cleaning apparatus having resilient lifters which overcome this and other difficulties. Preferably, the lifters according to the present invention are made of polyurethane and are used in combination with a conventional boom with or without splitters.

Abstract: An enzymatic process is presented for producing a desired protein from an amino terminal extended protein by reaction with one or more aminopeptidases, glutamine cyclotransferase and pyroglutamine aminopeptidase.

Abstract: A desired protein having the formula:A-B-C-Pwhereina) A is Lys or Arg, and B and C are arbitrary amino acids, orb) A is an arbitrary amino acid different from Pro, Lys and Arg, and B and/or C is Pro,is produced from a biosynthetically formed amino acid extended protein having the formula:X-A-B-C-Pwherein A, B, C and P are as defined above, and X is an amino acid sequence with an even number of amino acids, of which the first one, seen from the N-terminal end, is different from Lys and Arg, all other uneven amino acids are different from Pro, Lys and Arg, and all even amino acids are different from Pro, by reaction with the enzyme dipeptidyl aminopeptidase (DAP I). The desired protein is obtained in a pure state. Thus, e.g. hGH without content of Met-hGH may be produced by the process.
