Title: Drug delivery system for the simultaneous delivery of drugs activatable by enzymes and light
Inventor: KOPECEK JINDRICH
IPC: A61K47/48
Filed: 1993-01-21
Abstract: Compositions for the treatment of cancerous tissues in warm-blooded animals containing both an anticancer drug and a photoactivatable drug attached to copolymeric carriers are made up of a member selected from the group consisting of (a) a copolymeric carrier having attached thereto both an anticancer drug and a photoactivatable drug, (b) a mixture of copolymeric carriers wherein one copolymeric carrier has attached an anticancer drug and the other copolymeric carrier has attached a photoactivatable drug and (c) a combination of (a) and (b). The anticancer drug is attached to the polymeric carrier by side-chains which are stable in the blood stream of the warm-blooded animal but susceptible to hydrolysis by lysosomal enzymes intracellularly. The photoactivatable drug is attached by either the same degradable side-chain or by a non-degradable attachment. The polymer carrier may optionally contain a targeting moiety. Upon administration polymeric macromolecules enter targeted cancer cells by pinocytosis which reduces the side effects normally elicited by the free drugs. A time lag is allowed following administration for optimal uptake of the copolymers in the cancerous tissue for the anticancer agent to begin to take effect. Then a light source of the appropriate wavelength and energy is to activate the photoactivatable drug. The combined effect of the anticancer agent and photoactivatable drug provides greater cell destruction at reduced dosages and side effects.

Title: Elastic net-like substrate having a layer of fibers pre-bonded thereto for use in an absorbent article
Inventor: COLES PETER
IPC: A61F13/00
Filed: 1993-03-11
Abstract: In an absorbent article, such as a diaper or incontinence briefs, an elastic member (60) comprising a net-like elastic substrate (62) to which fibers (64, 66) are pre-bonded provides for a breathable elastic for use as a side- a waist- or leg elastic. The fibers that are bonded to the net-like substrate, for instance by hydro-entangling, ensure a soft and comfortable contact with the wearer's skin. In the side panels of the absorbent article, the elastic members have a large freedom of stretch without buckling taking place, thus reducing chances of leakage. When the elastic member is located between the topsheet and the backsheet, a strong connection of topsheet to backsheet is established using a relatively small amount of adhesive.

Title: Method of making a printed circuit board
Inventor: KNOPP JOHN FREDERICK DAVID
IPC: H05K3/42
Filed: 1993-06-01
Abstract: A method is provided for making a plate through hole printed circuit board.  The method includes the first step of forming conductive circuit elements on two opposed faces of a non-conductive substrate. The substrate and circuit elements are coated with a de-sensitising material, the de-sensitising material comprising an alkali-strippable material. Holes are formed through the substrate, each hole passing through a circuit element on each of the opposed faces of the board. The board is treated to render the substrate which is exposed in the holes receptive to the action of a metallic plating solution. The de-sensitizing material is removed by treating the board with an alkaline accelerator solution to accelerate the action of the sensitisation and simultaneously to remove the de-sensitising material. The board is finally treated with an electroless metallic plating solution to deposit conductive metal in the holes to a desired thickness to provide an electrical connection through each hole between two opposed conductive circuit elements.
