Title: Process for the extractive separation of l-phosphinothricin and l-glutamic acid in aqueous solution
Inventor: MILDENBERGER HILMAR
IPC: C07C229/24
Filed: 1991-08-22
Abstract: Abstract of the disclosure A process for the extractive separation of L-phosphino-thricin and L-glutamic acid in aqueous solution A large number of customary processes for separating amino acids fails when very polar hydrophilic amino acids with isoelectric points  (IEP) which are close to one another are to be fractionated. Mixtures of L-glutamic acid (IEP = 3.24) and L-phosphinothricin (IEP = 2.6) produced by enzymatic transaminations of the correspond-ing .alpha.-keto acid have been difficult to separate to date. The invention relates  to  a  process  for  separating L-phosphinothricin and L-glutamic acid, which comprises carrying out the separation as liquid/liquid extraction with two non-miscible aqueous phases as phase system, where the phase former contained in the phase system is a combination of at least two different water-soluble polymers or of at least one water-soluble salt and one water-soluble polymer, and the extraction is carried out by multistage countercurrent partition on the van Dijck principle.

Title: Alkaline resol phenol-aldehyde resin binder compositions
Inventor: SMITH GARRY
IPC: C08G8/10
Filed: 1992-02-17
Abstract: A binder composition for producing articles of bonded particulate material such as foundry moulds or cores comprises an alkaline aqueous solution of a resol phenol-aldehyde resin, an oxyanion which can form a stable complex with the resin, and pyrrolidone or an N-substituted pyrrolidone, and the amount of alkali present in the solution is sufficient to substantially prevent stable complex formation between the resin and the oxyanion. Bonded articles are produced by passing carbon dioxide gas through articles formed from a mixture of particulate material and the binder composition so as to produce stable complex formation and curing of the resin.

Title: Continuous backwash filter and method of operation
Inventor: JOHNSON BRUCE R
IPC: B01D24/30
Filed: 1992-05-15
Abstract: ABSTRACT OF THE DISCLOSURE A particulate media filter employing a continuous media backwash, designed to promote mass or plug flow of the filter media within a filtration vessel and to eliminate areas of stationary media particles.  The filter vessel contains a filter bed moving downwardly, countercurrent to an upwardly-moving solids-contaminated influent or feed stream.  The contaminated liquid is cleaned by its passage through the filter bed, and is removed as filtrate from a location in the vessel above the top of the filter bed.  The downwardly-moving filter bed media becomes progressively more contaminated, and is removed from the filtration stream near the bottom of the filter vessel for cleaning and recycling into the filter stream.  A frustoconical skirt-like perimeter feed profile is disposed on the interior of the vessel, surrounding a conical center feed profile, under which may be placed a coaxial center feed pipe.  A single, large, substantially unobstructed annular channel for countercurrent flow of influent and filter media is defined between the two profiles.  The influent is introduced into the filter vessel between the perimeter feed profile and the wall of the vessel, and under the center feed profile via separate feed distribution channels fed by a common feed header, subsequently entering the filtration  stream from underneath the profiles.

Abstract: A novel pneumatic tire is provided herein. The tire includes a tread portion, a pair of axially-spaced bead portions, a pair of sidewall portions extending between tread edges and said bead portions and a pair of bead cores, each bead core disposed in an associated one the bead portion. A carcass extends between the bead portions through the tread portion and the pair of sidewall portions. A belt is disposed radially-outside the carcass and extends across the width of the tread. Each sidewall portion is provided axially-inside of the carcass with an inside sidewall rubber layer, the inside sidewall rubber layer extending radially-inwardly to the bead portion and radially-outwardly into the tread portion along a convexly-curved inner surface of said carcass. The total thickness of the tire measured from the outer surface to the inner surface of the tire satisfies the condition that the total thickness (TA) is substantially-constant in a region (8), the region S being defined as extending between a maximum width point (A) at which the maximum width of the tire lies under an unloaded state, and a 65% height point (B) located at a 65% height (HB) of the tire section height (H), each being measured from the bead base line (b) under the unloaded state.      The unloaded state is such that the tire is mounted on its regular rim and inflated to its regular inner pressure but is loaded with no tire load. The total thickness (TC) measured at a contacting point (C) is larger than the total thickness (TA) in the region (S). The contacting point (C) is defined as a point at which the outer surface of the tire starts to contact with the radially-outer edge of a flange of the regular rim under the unloaded state.

Abstract: SOFT RELEASE CONTROL MECHANISM WITH SPRING CLUTCH                AND VISCOUS DAMPING          ABSTRACT     A control mechanism of the soft release type includes a cylindrical drum about which is concentrically arranged a helical clutch spring the coil turns of which are normally contracted radially inwardly into frictional engagement with the outer periphery of the drum, characterized in that the drum is formed of powdered metal that is impregnated with damping oil.  Owing to the direction of the coil turns, the drum may be rotated only in a first direction relative to the spring, and upon radial outward expansion of the spring, the viscous film of the dampening oil between the outer periphery of the spring affords controlled soft-release of the drum for rotation in the opposite direction.

Title: Concrete pile cutter
Inventor: TRUDEAU LEON B
IPC: E02D9/00
Filed: 1991-07-17
Abstract: A method and apparatus are described for preparing an end of a reinforced concrete pile (68). Excessive lengths of the driven pile are cut off using a shear blade (22) that is driven through the concrete and reinforcing steel (102) of the pile. Concrete is then removed down to a certain level below the cutoff position using a pair of blades (62) that engage the surface of the pile and penetrate the surface while wedging the upper part of the pile up away from the main body of the pile. This cracks the con-crete through at the desired position. At the same time, concrete breakers (88) engage the concrete pile above the blades to frac-ture the concrete from the reinforcing steel. This eliminates the need for cutting of the piles with explosives and the removal of concrete using pneumatic hammers.
