Title: Stabilized interface for iontophoresis
Inventor: IGA KATSUMI
IPC: A61N1/30
Filed: 1996-03-15
Abstract: An interface is formed by incorporating (1) a mixture comprising a water-soluble protein and a drug into a matrix, or preferably (2) a mixture comprising a water-soluble protein and a drug to a porous matrix coated with a cationic surfactant or other ionic surfactant.  The coating amount of the ionic surfactant is about 0.1 to 50 µg, and the content of the water-soluble protein is about 0.1 to 1,500 µg, each per 1 cm2 of the matrix.  The water-soluble protein includes an albumin and the drug includes a physiologically active peptide or protein, for example.  The use of the stabilized interface inhibits decrease of the drug retaining amount, and insures an effective transdermal drug delivery with high a repeatability and accuracy.

Inventor: MEYER STEVEN J
IPC: B29C48/09
Filed: 1996-10-31
Abstract: Multilayer fluid conduits are formed by adhering to a tubular outer surface of a metal pipe, a thermoplastic outer layer. The outer layer permits ends of the multilayer conduit to be joined together in leak-proof fluid conduit systems simply by adhering the conduit ends with compatible thermoplastic fittings. For fire protection systems, the preferred metal is steel, the preferred thermoplastic is CPVC and the preferred adhesive is heat activated. The adhesive coated metal pipe is preheated and the CPVC is extruded onto the outer surface of the heated metal pipe. Through the use of fire resistive CPVC, the multilayer conduit systems of the present invention can be installed in more severe fire threat areas than can existing, all plastic piping, including all CPVC piping systems. The conduit is assembled into systems on site simply by cutting and direct bonding with ordinary, all plastic fittings using appropriate bonding agents such as solvent based adhesives. CPVC fittings are preferred for fire protection systems.

Title: Method for generating a handoff candidate list
Inventor: GARNCARZ JEFFREY ROBERT
IPC: H04W36/32
Filed: 1996-04-05
Abstract: In a cellular communication system (40) a handoff candidate list is generated for a source sector (51) by eliminating (12) from a list of potential handoff candidates (52-56) any sectors having an interference parameter exceeding a threshold value. The list is further reduced by determining (21) a handoff radius (60) and eliminating any candidate sectors (52-56) that fall outside the hadoff radius (60). Candidate sectors (52-56) that do not have overlapping coverage areas are also eliminated (23). In addition, candidate sectors (52-56) having a relative angle of sight to the source sector (51) that exceeds a maximum angle are also eliminated (24). Finally, the list is reduced (15) to a preset number of candidates dependent upon the interference parameter.

Title: Method of applying phosphate coatings to metal surfaces
Inventor: SCHIEFER PETER
IPC: C23C22/18
Filed: 1995-12-05
Abstract: The proposed method of applying phosphate coatings to surfaces of zinc, iron, aluminium or alloys of those metals, involves wetting the surfaces with a phosphatising solution which contains no sub-group 5 or 6 elements, 0.5-8 g/I nickel, 2-20 g/l manganese, 18-170 g/l phosphate (in the form of P2O5) and has an acid number of 0.4-0.8. The wetting is done in such a way that, after the subsequent drying-on process, a phosphate layer with a weight per unit area of 0.3-3.0 g/m2 is produced. In the case of surfaces of iron, aluminium or alloys thereof, the phosphatising solution must contain 0.5-5.0 g/l of zinc. In the case of zinc or zinc alloy surfaces, the solution need not, and preferably should not, contain zinc. The process according to the invention can be used to particular advantage in the phosphatisation of zinc-plated or zinc alloy-plated steel strip.
