Title: Improved methods and composition for making a pressure sensitive adhesive coated laminate
Inventor: SMITH JOHN R
IPC: C09J183/12
Filed: 1994-03-28
Abstract: A method for making an improved pressure sensitive adhesive coated laminate is disclosed. The method involves coating a sheet having a release surface thereon with a pressure sensitive adhesive to form a laminate, drying or curing the pressure sensitive adhesive and marrying the laminate to the inner surface of a facing layer. A material comprising a mixture of substantially water-insoluble and adhesive incompatible polysiloxane (i) and water soluble and adhesive compatible polysiloxane (ii) is included so as to produce a low zero-minute peel value in the pressure sensitive adhesive layer is intimately mixed with the pressure sensitive adhesive prior to the adhesive being coated on the release surface of the sheet.      The resulting laminate can be easily applied to a substrate and removed and repositioned or straightened, if necessary, and provides a superior increase in peel value over a period of time to produce a more permanent installation.      The laminate is suitable for use as decorative and/or protective covering as well as adhesive tapes, labels, and the like.

Title: Enzymatic preparation of n-(phosphonomethyl) glycine
Inventor: ANTON DAVID L
IPC: C12P7/40
Filed: 1992-11-03
Abstract: The invention provides a process for producing mixtures of glyoxylic acid and aminomethyl phosphonic acid and the subsequent production of N-(phosphonomethyl)glycine, also known as glyphosate.  The process comprises preparing in situ a mixture of glyoxylic acid and aminomethylphosphonic acid (AMPA) by enzymatically reacting glycolic acid and oxygen in an aqueous solution in the presence of aminomethylphosphonic acid and catalysts consisting of glycolate oxidase and catalase. The resulting mixture is then hydrogenated to produce N-(phosphonomethyl)glycine, a post-emergent phytotoxicant and herbicide.

Patent CA-2140772-A1 (CA)
Title: Needleless hypodermic injection methods and device
Inventor: PETERSON STEVEN F
IPC: A61M5/30
Filed: 1993-07-23
Abstract: A needleless injection device (20) includes an initiator valve (144) controlling flow of compressed gas into a reservoir (168). A poppet valve (170) connecting to the reservoir has a gas pressure regulation end to regulate flow from the initiator valve into the reservoir. A clamp piston (210) is driven forward by gas pressure from the reservoir and causes jaws (236) to clamp onto a plunger (362) extending into an ampule (360). The poppet valve opens when reservoir pressure reaches the cracking pressure of the poppet valve. Gas from the reservoir rushes through the poppet valve into a drive chamber and forces a drive piston (212), containing the clamp piston and jaws, forward causing the plunger to slide into the ampule. A jet of injectant is ejected out of the nozzle of the ampule and penetrates through the patient's skin. An improved method of needleless injection uses a specific pressure profile, ampule nozzle diameter, patient, injection site, and injectant parameters.

Title: Titration emulation system and method
Inventor: MACRI TIMOTHY FRANCIS
IPC: G01N33/536
Filed: 1995-05-02
Abstract: A method and system achieving the results of a conventional titration without the need to chemically dilute a sample. Such a result is accomplished by providing a plurality of calibration standards, each containing a different known concentration of a visualizable material. The visualizable material contained within each calibration standard is then visualized, the parameters of the visualization forming a setting. The visualization is then altered by adjusting at least one parameter of the visualization until the point where the visualizable material within each calibration standard can no longer be visualized within the solution. The visualizable material within a sample solution having an unknown concentration of the visualizable material is then visualized using settings corresponding to the plurality of calibration standards to generate a number of modified visualizations, each modified visualization corresponding to the concentration of the standard to which it relates. The modified visualization at which point the visualizable material can no longer be visualized is then correlated with the corresponding concentration, to determine the titration of the sample solution.
