  • Patent number: 8864664
    Abstract: A medical device for carrying out at least one medical function. The medical device comprises at least one control part, which can be applied to a body surface of a user, and at least one functional element, which can be inserted into a body tissue of the user at at least one insertion site. The functional element can be connected to the control part. The functional element is designed to carry out at least one medical function. The control part has at least one base part with at least one supporting surface, which faces the body surface. The base part has at least one collection channel for collecting bodily fluid emerging from the insertion site.

  • Publication number: 20140109937
    Abstract: A medical device kit includes a medical instrument with a first connector. The first connector includes at least one first electrical connection. The first connector further includes a sealing cavity at least partially surrounding the at least one first electrical connection. The sealing cavity includes a sealing surface and a wedging surface. The kit includes a sealing cap having a sealing tube with an inner cavity and a flexible tip region. The wedging surface is operable for forcing the flexible tip against the sealing surface to form a flexible tip seal that seals the at least one first electrical connection within the sealing tube.

  • Patent number: 8507605
    Abstract: The present technology provides a latex comprising: a mixture of microgels and sol polymers of an acrylic copolymer, wherein the Mc of the acrylic copolymer is greater than or equal to the Me thereof; the Mw of the sol polymers is greater than or equal to twice the Me of the acrylic copolymer; the amount of sol polymer having a Mw less than twice the Me of the acrylic copolymer is about 20 wt % or less than 20 wt %. Such lattices may be used to form films for use as adhesives such as pressure sensitive adhesives. Also provided are methods for manufacturing the films and adhesives.

  • Patent number: 8475542
    Abstract: A method for producing a fuel or fuel additive comprising providing a reaction mixture comprising oil and an alcohol in an oil-in-alcohol emulsion and a catalyst for converting the oil to the fuel or the fuel additive. The oil and the alcohol are reacted in the presence of the catalyst, at a concentration below that used in a conventional batch process, to produce the fuel or fuel additive. This low level of catalyst reduces the formation of diols and oxidation products that can diminish the quality of the fuel or fuel additive. The fuel or fuel additive produced is continuously removed during the reaction, effectively de-coupling the concentration of catalyst used from the rate of the two phase reaction.

  • Publication number: 20130131321
    Abstract: The present invention relates to the use for affinity purification of an antibody or an fragment of an antibody, of a ligand-substituted matrix comprising a support material and at least one ligand covalently bonded to the support material, the ligand being represented by formula (I) wherein Sp is a spacer group; v is 0 or 1; Am is an amide group —NR1—C(O)—, and wherein either NR1 is attached to Ar1 and —C(O)— is attached to Ar2, or —C(O)— is attached to Ar1 and NR1 is attached to Ar2; and R1 is hydrogen or C1 to C4 alkyl, preferably hydrogen or methyl; and more preferably hydrogen; Ar1 is a divalent 5- or 6-membered substituted or unsubstituted aromatic ring; Ar2 is 5- or 6-membered heterocyclic aromatic ring which is (a) attached to a further 5- or 6-membered aromatic ring via a single bond; or (b) fused to a further 5- or 6-membered aromatic ring as part of a multicyclic ring system; or (c) attached to at least one substituent selected from C1 to C4 alkyl; C2 to C4 alkenyl; C2 to C4 alkynyl; a

  • Patent number: 8366794
    Abstract: An apparatus for the production of a bio-fuel or a bio-fuel additive from plant-derived oils, animal fats or a mixture thereof, suitable for use in a diesel engine is disclosed. The apparatus comprises a porous membrane for separating a reaction mixture from a permeate, the reaction mixture comprising an alcohol, a feedstock comprising plant-derived oils, animal fats or mixture thereof, and a catalyst for converting said feedstock to a bio-fuel or a bio-fuel additive, wherein said porous membrane is substantially impermeable to the feedstock and substantially permeable to said bio-fuel or bio-fuel additive. A method using said porous membrane in the production of a bio-fuel or a bio-fuel additive is also disclosed.
