Granted: 2001-07-10
Abstract: A process for preparing high density detergent compositions is provided. The process comprises the steps of: (a) continuously mixing a detergent surfactant paste and dry starting detergent material into a high speed mixer/densifier to obtain detergent agglomerates, wherein the ratio of the surfactant paste to the dry detergent material is from about 1:10 to about 10:1; (b) mixing the detergent agglomerates in a moderate speed mixer/densifier to further densify and agglomerate the detergent agglomerates; and (c) drying said detergent agglomerates so as to form the high density detergent composition. The dry detergent material may contain a builder material including a crystalline microstructure in which a carbonate anion, a calcium cation and at least one water-soluble cation are contained. The process may include one or more additional processing steps such as adding a coating agent such as the builder material described herein after the moderate speed mixer/densifier to facilitate and control agglomeration.

Abstract: A compact portable instrument for determining the percentage concentration of a material in a solution such as the amount of concentrate in an output from an Aqueous Film Forming Foam generator used to extinguish fires. The instrument comprises a refractive index sensor with a reflective type refractometer prism having a measuring surface in contact with liquids placed in a sample holder formed by an opening through a retainer plate. The measuring surface of the prism covers that opening and presses the retainer plate towards an outer surface of the instrument, that outer surface having entrance and exit ports for sample liquids at that opening. The refractometer senses the refractive index of liquid in the sample holder and, when properly calibrated, provides an output to a digital display that directly indicates the percentage concentration of material in the liquid. A small thin sample size of about 100 microliters provides rapid thermal stabilization of the sample liquid and allows the percentage concentration to be quickly and accurately determined.

Abstract: A method is described for stereoselectively reducing an unsaturated alkyl ketone substituent attached to a fused ring base. In this method, the unsaturated alkyl ketone reacts with a chiral oxazaborolidine reagent. This reaction stereoselectively reduces the unsaturated alkyl ketone to an unsaturated alkyl alcohol. The unsaturated alkyl alcohol can be further reduced, if desired, to produce a saturated alkyl alcohol. The fused ring ba se can be, for example, a steroid ring base or a base of a vitamin D analog. Th e process in accordance with the invention can be used with an alkeneone substituent (e.g., a 22-one-24-one substituent) or an alkyneone substituent (e.g., a 22-yne-24-one substituent) on a steroid ring base to make squalamin e or other useful aminosterol compounds and intermediates for making aminoster ol compounds.

Abstract: A concrete reclaimer having a pair of concentric mesh cylinders for separating wet concrete into its original components. The invention includes a hopper and feed screw for feeding wet concrete into the inner cylinder at a constant rate. The concrete is washed by a water spray as it passes through the cylinders.      The inner cylinder is made from coarse mesh which allows sand and cement, but not gravel, to pass through. Gravel is deposited from the outlet end of the inner cylinder. The outer cylinder is made from fine mesh, allowing cement, but not sand, to pass through. Sand is deposited into the bottom of at least one dewatering screw, which allows water to drain as it elevates the sand. The dewatering screw is in thermal contact with a heated liquid tank to prevent the water from freezing. The cement is dropped through the outer cylinder into a series of settling ponds, where it is allowed to settle out of the water.

Abstract: A selectively closeable plastic film bag is formed with front and rear plastic film panels. The bag includes a bottom and side edges and each of the front and rear panels include a top edge whereat an opening is provided into the bag cavity. An adhesive strip is provided on the inside surface of the front or rear panels extending longitudinally thereacross between the bag side edges. The adhesive strip is placed in a pattern extending at an angle upwardly from each of the side edges to a generally linear portion therebetween. A release liner is provided between the front and rear panels and is located partially over or above the adhesive strip at the side edges and below the linear adhesive strip portion. The adhesive strip portion covered by the release liner is prevented from coming in contact with the other bag panel thereby retaining the bag open. The release liner is detachably attachable to the adhesive strip. For closing the bag, the release liner is pulled out from between the panels causing the adhesive strip to come in contact therewith. The adhesive strip extends uninterrupted from side edge to side edge thereby making the closure leakproof. Pocket panels are attached to the bag thereby forming pockets for selectively receiving items therein. The front and rear panels are provided with weakened material lines extending between the side edges for easily ripping and gaining access to the bag cavity. To prevent fusing of the release liner to the front and rear panels, both the release liner and front and rear panels are cut away at the bag side edges above the adhesive. The release liner extends above the front and rear panels top edges or into notched areas at the bag side edges whereat it may easily be gripped.
