Title: Method of making a printed circuit board
Inventor: KNOPP JOHN FREDERICK DAVID
IPC: H05K3/42
Filed: 1994-12-02
Granted: 2004-02-17
Abstract: A method is provided herein for making a printed circuit board. The method includes the first step of forming conduc-tive circuit elements on two opposed faces of a paper phenolic-containing substrate. The substrate and the conductive circuit elements are then coated with a desensi-tising 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 then treated to render the substrate which is exposed in the holes receptive to the action of a metallic plating solution. The de-sensitising material is then removed. An acid-resist mask is presented onto both faces of the board, the mask leaving exposed only a small area of the board surrounding each hole therethrough.      Finally, the board is treated with an electroless nickel-plating solution to deposit nickel in the holes to the desired thickness to provide an electrical connection through each hole between two opposed conductive circuit elements.

Patent CA-2238021-C (CA)

IPC: H03H21/00
Filed: 1996-11-22
Granted: 2005-06-14
Abstract: A decoder capable of decoding audio signals encoded using analog noise reduction techniques, particularly Dolby SR, is implemented by means of digital signal processing. The typical decoding paradigm used by analog Dolby SR decoders is modified to overcome the problems caused by delay which is introduced by the digital implementation. A gain factor is factored out of the feedback transfer function and is placed in the forward signal path of each stage of the digital decoder. A single control circuit can then be used to generate coefficients which define transfer functions of each filter stage of the signal path. Linear interpolation techniques are used to limit the number of coefficient entries necessary to emulate the transfer function of an analog Dolby SR decoder. The digital decoder structure can be inverted to produce a digital encoder which is capable of implementing any noise reduction standard desired, including Dolby SR.

Title: Denaturants for sympathomimetic amine salts
Inventor: NICHOLS W MICHAEL
IPC: A61K31/135
Filed: 1997-04-01
Granted: 2008-06-10
Abstract: The present invention is directed to the addition of one or more pharmaceutically and biologically acceptable denaturants to sympathomimetic amine salt-containing pharmaceutical products to make these products less suitable as starting materials for the production of illegal drugs. In one preferred embodiment, the denaturant(s) and the sympathomimetic amine salt exhibit similar chemical and/or physical properties, so that purification of sympathomimetic amine by conventional extraction techniques is rendered difficult or essentially infeasible. In another preferred embodiment, the denaturant physically interferes with the extraction of the sympathomimetic amine salt from the pharmaceutical products i.e., emulsifies and/or alters the viscosit y of the pharmaceutical products in solution). Because the separation of denaturant(s) from the sympathomimetic amine salts is rendered impracticable, attempts to isolate the sympathomimetic amine salts from compositions of the invention are unsuccessful or results in preparations that are converted into adulterated illegal drug products. The present invention is directed to denaturant-containing sympathomimetic amine products and to methods for their preparation. The denaturant-containing sympathomimetic amine products are used for known indicationstreated by sympathomimetic amines.
