Antimicrobial solution and methods of making and using the same
Patent No. 9,132,296
A chitosan solution is formed from chitin, which is a homopolymer of beta (1-4)-linked N-acetyl-D-glucosamine. Rinsed, dried and ground chitin undergoes a process of deacetylation to convert some N-acetyl glucosamine to glucosamine, a primary component of chitosan. The chitosan solution is prepared by mixing 5chitosan with an alpha-hydroxy acid such as glycolic acid. An aqueous chelated silver solution is prepared by mixing silver oxide with a carboxylic acid such as citric acid. The chitosan solution can then be mixed with the silver solution resulting in a cationic complex. The cationic complex of the present invention may then be electrostatically bonded with generally negatively charged surfaces. In use, citrate promotes uptake of the silver by microbes. The antimicrobial complex can be applied via several methods of application, including an impregnated wipe, a foam, a gel, a spray, a lotion and an ointment.

Methods for making polymer particulates in gel form
Patent No. 9,133,337
Methods for making polymer particles in gel form via an emulsion and/or suspension process are provided. The method can include preparing a reactant mixture comprising a carrier fluid and a monomer component containing one or more phenolic compounds and optionally one or more crosslinking compounds, a mixture of Maillard reactants, or a combination thereof. The monomer component can polymerize to form the polymer particles in gel form. The reactant mixture can be located within a reactor having one or more inner surfaces in contaConn. with the reactant mixture during polymerization of the monomer component. The one or more inner surfaces limit a release of metal, metal ions, or a combination thereof into the reactant mixture to produce the polymer particles in gel form containing less than 1 wt % metal atoms, metal ions, or a combination thereof, based on the total weight of the polymer particles in gel form.

Toaster with keep warm feature and method of toasting with the same
Patent No. 9,131,804
A toaster comprises a housing, at least one spring-loaded bread tray, one or more heating elements, a bread tray retaining mechanism, a bread tray partial retaining mechanism, and a lifter arm slot. The bread tray is movable between an up position and a down position and is biased toward the up position. The bread tray retaining mechanism selectively retains the bread tray in the down position while the toasting operation is in progress and releases the bread tray from the down position when the toasting operation is complete. The bread tray partial retaining mechanism selectively retains the bread tray in a position between the down position and the up position after the bread tray is released by the bread tray retaining mechanism. In one embodiment, the lifter arm slot comprises an upper portion and a lower portion, the lower portion being wider than the upper portion.

Brush seal cover assembly
Patent No. 9,140,363
A brush seal cover assembly that includes a brush cover having a shroud that substantially encloses a brush mounted in a holder without removing the holder from the equipment to which it is mounted. The assembly includes a pair of brush cover halves integrally formed to provide an outer bristle guard capable of supporting the weight of a person and a pair of brush shields on opposite sides of the brush that prevent direct impingement of pressurized gas or liquid enabling maintenance and cleaning of the equipment to be performed while leaving the brush mounted in place without damaging the brush. The cover includes a pair of mounting plates configured for mounting of the cover by clamping or by compression between fasteners without having to remove the brush holder from the equipment or the brush from the holder.

Flavor pouch
Patent No. 9,139,360
A flavor pouch includes a porous covering that encloses a carrier having a flavorant. The carrier may be solid or particulate. Flavorants may be one or more of tea, coffee, rose hips, honey, royal jelly, fruit extracts, mint, sweeteners, ginger, pepper extracts., exotic flavors, ethnic flavors and the like. Where the carrier comprises a plurality of beads, the beads may have randomly dissolvable encapsulation to extend the time duration of flavor release. To use the flavor pouch, it is placed in the mouth and masticated or exposed to saliva to thereby release the flavorant.

Ultrasound detectable interventional medical device
Patent No. 9,138,286
An interventional medical device for use with a motion-sensitive ultrasonic imaging system comprising a flexible elongated member for insertion into soft tissue, a two-axis, flexing mechanism coupled to the flexible elongated member and a mechanism for controlled electrical excitation of the flexible elongated member. Each of the axial flexing mechanisms, when acted upon by electrical excitation, forcibly bends the elongated member along a section of it length causing its tip to move in the plane of the applied bending force. As a direct result of direct energy coupling by bending rather than vibration, the relative phases of the two axes can be controlled to accomplish specific movement of the tip of the flexible elongated member.
