Title: Process and intermediates for the preparation of an antiviral agent
Inventor: GODFREY JOLLIE D JR
IPC: C07C69/743
Filed: 1992-09-30
Abstract: ABSTRACT   Process And Intermediates For The Preparation Of An Antiviral Agent Racemic Feist's acid is treated with (R)-(+)-a-methylbenzylamine to yield (lR-trans)-3-methylene-cyclopropane-1,2-dicarboxylic acid, (R)-.alpha.-methylbenzyl-amine (1:1) salt.  This salt can then be converted to (lR-trans)-3-methylene-1,2-cyclopropanedicarboxylic acid, dimethyl ester which is an intermediate in the preparation of the antiviral agent [1R-(1.alpha.,2.beta.,3.alpha.)]-2-amino-9-[2,3-bis(hydroxymethyl)cyclobutyl]-1,9-dihydro-6H-purin-6-one.  The improved process also enables the recovery of racemic Feist's acid from the resolution.

Abstract: PROCESS FOR MAKING CHOLESTEROL LOWERING SAPONINS      ABSTRACT      Disclosed is a process for preparing novel compounds containing 5-C-hydroxymethylhexose and a sterol or triterpene.  These materi-als, when consumed by humans and animals, lower the cholesterol level in the blood.  The compositions are prepared by preparing and then reacting a fluoro or bromo hexaacylated 5-C-hydroxymethylhexose with a sterol.  In a second method the hexaacylated 5-C-hydroxymethylhexose is reacted with a sterol in the presence of trimethylsilyl trifluoromethane sulfonate.

Title: Apparatus and method for locating a breast mass
Inventor: DEBBAS ELIE
IPC: A61F2/958
Filed: 1990-04-26
Abstract: A mass localization device includes a catheter (12) and a needle (30). The catheter includes inner (18), and outer (20) walls spaced from each other and creating a gap (22) between the walls extending along substantially the entire length of the catheter.   The distal portion (28) of the outer wall includes an inflatable balloon. A  port extension member (38) is provided at the proximal end of the catheter for communicating a supply of air to the inflatable balloon via the gap between the inner and outer walls of the catheter. The needle is insertable through the catheter to extend beyond the distal end of the catheter. In use, the combination of the needle and catheter are inserted.into body tissue. Under assistance of x-ray radiography, the device is moved toward a mass in the tissue. Once proximate the mass, an anesthetizing agent is introduced into the tissue through the needle. Subsequent-ly, the balloon is inflated for contacting the mass, and thus making the mass palpable. The needle is withdrawn from the catheter, and the patient is prepared for a biopsy or other medical procedure. An incision to the mass can be achieved by the shortest possi-ble distance since the mass is made palpable.

Abstract: A B S T R A C T   In a preferred embodiment a frameless building includes a first set of four walls each in the form of a profiled trapezoidal shaped wall panel. Each panel includes a left and right side set of sub-panels each set comprising a bottom, middle and a top sub-panel. The left side edge of one panel is attached to the right side edge of another panel. All the panels are attached in this manner to lean towards one another and towards the inside of the building. A profile between the top and bottom edges of each panel defines a plurality of Ls. One L proceeds into another L, a first leg of an L facing upwards and a second leg of the L outwards when travelling between the top and bottom edges. This profile allows for thermal insulating screed to be applied to the outer surfaces of each panel; structural rigidity, stackability of similar sub-panels and for solar heating. Alternative to the screed a second set can be arranged over the first set of wall panels and insulating filler material provided between the two sets. The invention extends to the sub-panels for use in the building and to a method of constructing the building.

Abstract: COLOR PRINTING METHOD BASED ON          UNLIMITED VIRTUAL OR IMAGINARY SCREENS HAVING     HALFTONE DOTS OF A SINGLE OR MIXED TYPE DISTRIBUTION                   ABSTRACT OF THE DISCLOSURE    A color printing method is disclosed which is based on virtual or imaginary screens having halftone dots of a single or mixed type distribution . Virtual screens are related to the printing process in which a media is used to transfer the halftone dots pattern to the press' actual printing unit . Imaginary screens are related to any printing process in which a specific digitally manipulated halftone dots pattern activates the printing engine within various equipment such as : computer to plate presses, plotters, printers, copying or facsimile machines, proofers . By properly selecting the halftone dots distribution, that can be either of single or mixed type within one screen or within the separation screens , it is possible to cancel any linear, worm or rosette type Moiré artifacts without inducing tonal rendition shifts . In addition to these merits, the improved and versatile halftone dots distribution allows the Moiré free printing of unlimited subtractive and/or additive colors by using fairly less accurate, thus substantially less expensive printing equipment.
