Abstract: A method and apparatus for efficiently repairing or reworking a printed circuit board having a solder ball grid array thereon efficiently and at minimum cost includes the steps of drilling out a plated-through hole to sever electrical connections between a ball grid array pad on one surface of the printed circuit board and internal circuits and circuits on an opposite surface of the printed circuit board; inserting a pin having an insulated sleeve surrounding a portion thereof into the drilled-out hole, the pin having attached to one end a wire for attachment to the ball grid array on one surface of the printed circuit board and a post at the other end of the pin for attachment of a wire to the post; the pin having a stop along its length to control vertical positioning of the pin in the drilled-out hole, the pin referred to as a via replacement (VR) pin.

Abstract: A method for the manufacture of N,N dialkylglycamine compounds of general formula R.sub.2 NR.sub.1 R.sub.3 (I) by reacting a secondary amine of general formula R.sub.2 NHR.sub.3 (II) in which R.sub.2 is a straight or branched chain alkyl or hydroxyalkyl group having from 1 to 4 carbon atoms and R.sub.3 is a residue from a monosaccharide, with an alkali metal or alkaline earth metal aliphatic sulphate, R.sub.1 SO.sub.4 M, in which R.sub.1 is a straight or branched chain alkyl or alkenyl group having from 8 to 24 carbon atoms.The betaine, suphobetaine and N-oxidised derivatives of (I) are provided for use as mild surfactants.

Abstract: A process for the preparation of an extract from human placenta containing glycosphingolipids and endothelin-like peptides useful for the treatment of vitiligo is disclosed.

Abstract: A container for storing and shipping produce made from a blank having top, bottom and side panels with apertures therein defining cut-out areas allowing the passage of vapor through the container, at least some of the apertures overlapping the top and side panels and/or the bottom and side panels, wherein the cut-outs area of the apertures in the top and bottom panels exceeds the cut-out area of the apertures in the side panels.

Abstract: A printed circuit board or card for direct chip attachment that includes at least one power core, at least one signal plane that is adjacent to the power core, and plated through holes for electrical connection is provided. In addition, a layer of dielectric material is adjacent the power core and a circuitized conductive layer is adjacent the dielectric material, followed by a layer of photosensitive dielectric material adjacent the conductive layer. Photodeveloped blind vias for subsequent connection to the power core and drilled blind vias for subsequent connection to the signal plane are provided. Also provided is process for fabricating the printed circuit board or card for direct chip attachment.

Abstract: A pharmaceutical formulation useful for treating patients suffering from thalassemia, which comprises powder of Anemonin Pretensis in an amount in the range of 0.02 to 0.12 wt % of the formulation, quinine sulphate in an amount in the range of 0.0005 to 0.003 wt % of the formulation, distilled or demineralised water in an amount in the range of 0 to 40 wt % of the formulation and, ethanol in an amount in the range of 99.88 to 60 wt % of the formulation; and a process for preparing the formulation by mixing the above ingredients.

Abstract: The invention provides novel thermoplastic films produced by the blown tube process having improved and balanced characteristics. The improved film is characterized by crystallites dispersed throughout the film in amorphous areas and which is substantially free of crystalline formation, as well as having improved other properties. The film is produced by acting on a molten tube following extrusion to cool the tube to a temperature above the crystalline formation temperature, followed by an annealing step and a second cooling step to initiate solidification of said tube.
