Inventor: BOAZ NEIL W
IPC: C12R1/39
Filed: 1990-09-17
Abstract: R- and S-1-Phenyl-1,3-propanediol, each of high optical purity, were prepared by a chemoenzymatic sequence starting with ethyl benzoylacetate. The first step was a catalytic hydrogenation of the .beta.-ketoester conducted at room temperature. The en-zymatic hydrolysis of the resulting hydroxyester proceeded in a facile manner using a commercial preparation of the lipase from Pseudomonas fluorescens. The enzymatic hydrolysis proceeded at a moderate rate (350 mg lipase/0.10 mol of racemic ester re-quired a 20-hour reaction time with an enantiomeric rate ratio (E value) of 36). The hydrolysis was run to 45-50 % conversion to afford isolated S-3-phenyl-3-hydroxypropionic acid of 85-90 % ee after separation from the residual ester (aqueous base extrac-tion). The optical purity of the hydroxy acid was determined by conversion to the methyl ester (CH3I, KHCO3, acetone) and de-rivatization with S-MTPA-CI, and ?H NMR analysis. A single recrystallization of the isolated acid afforded optically pure (>98 % ee) S-3-phenyl-3-hydroxypropionic acid in an overall 36% yield from the racemic ester. The acid was reduced with bo-rane in THF to afford optically pure S-diol in 97 % yield after crystallization. The overall sequence proceeded in 34 % total yield from racemic ester with an additional 45-55 % recovered as the antipodal ester. This antipodal ester is obtained in 85-95 % ee, and the corresponding hydroxy-acid was readily obtained (NaOH, CH3OH/H2O) and recrystallized to optical purity. Reduction then afforded R-1-phenyl-1,3-propanediol in 30 % to overall yield from racemic ester.

Title: Liquid treatment method and apparatus
Inventor: STRUEWING JOHN W
IPC: C02F3/30
Filed: 1993-01-19
Abstract: An improved method and apparatus for treating liquor containing biodegradable wastes wherein the liquor is first  delivered to a quiescent primary settling zone and then to an aeration zone.  The aerated liquor is delivered downwardly through a column of submerged fixed media having a high surface area to volume ratio so that aerobic microorganisms can grow on their surface.  The liquor is recirculated through the aeration zone and fixed media, and is withdrawn from the unit after treatment.  A portion of the aerated liquor from the top of the fixed media is  recycled back into the primary settling zone to denitrify the nitrate rich aerated liquor by deoxygenating the dissolved nitrates and to equalize the BOD load in the secondary aerobic treatment zone.

Title: Multiple-based panelized log building system
Inventor: STRONG WARREN E
IPC: E04B1/10
Filed: 1993-08-04
Abstract: ABSTRACT Building a conventional log home involves the use of full logs, and can require the use of heavy equipment or extended site labour over a period of days. Special construction techniques are required to compensate for settling and wastage due to imperfections in logs, which can be substantial. The end results are longer construction periods, higher construction and higher manufacturing costs. Highland Homes process of a panelized log wall system eliminates the need for heavy machinery and equipment, using panel sizes that can be erected manually. Wastage is kept to a minimum as imperfections are removed and the rest of the log is utilized. The panels design eliminates settling. The result is a quicker. more efficient building process which is cost efficient and provides a higher quality wood finish on site. The concept of standard panels enables production runs in the plant, producing hundreds of panels at a time, not tied to any particular home, greatly simplifying manufacturing.

Inventor: BEARD TERRY D
IPC: G11B27/32
Filed: 1993-08-02
Abstract: A digital sound system for motion picture films employs a digital time code (20) on the film (4) to trigger the transfer of sound data from a digital audio store (40) to a FIFO memory (42). The digital audio data is read out from the FIFO memory and played back in the theater at a constant rate, with any jumps in the digital time code handled by making a corresponding jump within the digital audio store but not in the FIFO memory. Readout from the FIFO memory and clocking of the digital-to-analog converters (DACs) (DAC 1-4) used for theater playback is synchronized to the AC mains (54) that powers the theater projector, and thus allows for an uninterrupted audio playback even if time code entries on the film are obliterated. The FIFO memory need only have enough capacity to accomodate the maximum audio store access time, and can be quite small.
