| 20100258116 | DEVICES, SYSTEMS AND METHODS FOR REDUCING THE CONCENTRATION OF A CHEMICAL ENTITY IN FLUIDS - A device for removal of at least a portion of carbon dioxide from an aqueous fluid includes at least one membrane through which carbon dioxide can pass to be removed from the fluid and immobilized carbonic anhydrase on or in the vicinity of a first surface of the membrane to be contacted with the fluid such that the immobilized carbonic anhydrase comes into contact with the fluid. The first surface exhibits carbonic anhydrase activity of at least 20% of maximum theoretical activity of the first surface of the membrane based on monolayer surface coverage of carbonic anhydrase in the case that the carbonic anhydrase is immobilize on the first surface. | 10-14-2010 |

| 20090079162 | TRAILER HITCH RECEIVER LOCK - A freely pivoting lock ball fits within a trailer hitch ball receiver. A top lock shaft on the ball extends up through a hole in the top of the ball receiver into a lock collar welded to the top of the ball receiver. A cylinder lock fits into a top opening in the lock collar over the lock shaft to lock the lock ball within the ball receiver to prevent theft by towing the trailer with a conventional towing hitch ball. The cylinder lock and lock ball spin freely within the ball receiver and collar to prevent drilling or sawing the lock. There is no room between the cylinder lock and collar or between the ball lock and ball receiver to pry them loose. The lock collar is too thick for cutting with a bolt cutter. | 03-26-2009 |

| 20100288285 | TOOTHED VASECTOMY CLAMPS AND METHODS OF USING SAME - Apparatus and methods for performing vasectomies are disclosed. In preferred embodiments, a clamp has a set of jaws, the distal ends of which terminate in a partial or completely circular structure that is essentially a split ring. The ring may include pointed tips structured to pierce the vas deferens. The tips engage opposing sides of the vas deferens. Various embodiments of the toothed clamps may be preferred for “open” versus “closed” vasectomies. | 11-18-2010 |

| 20110168720 | Ready-Made Meal Package - A meal package includes a reusable bag and first and second inserts arranged in the reusable bag to form compartments. The first insert has a first side edge and a second side edge and includes bottom and top portions bent out-of-plane from a side portion at first and second score lines. The second insert has a top edge and a bottom edge and includes two side portions bent out-of-plane from a middle portion at first and second score lines. The bottom portion of the first insert is located adjacent a bottom of the bag and the side portion of the first insert is located adjacent a first side of the bag. The bottom edge of the second insert abuts an interior surface of the bottom portion of the first insert. An interior surface of the top portion of the first insert abuts the top edge of the second insert. | 07-14-2011 |

| 20100051560 | WASTE WATER TREATMENT APPARATUS AND METHODS - An improved draft tube spout fluid bed (DTSFB) mixing, handling, conveying, and treating apparatus and systems, and methods for operating are provided. The apparatus and systems can accept particulate material and pneumatically or hydraulically conveying the material to mix and/or treat the material. In addition to conveying apparatus, a collection and separation apparatus adapted to receive the conveyed particulate material is also provided. The collection apparatus may include an impaction plate against which the conveyed material is directed to improve mixing and/or treatment. The improved apparatus are characterized by means of controlling the operation of the pneumatic or hydraulic transfer to enhance the mixing and/or reacting by controlling the flow of fluids, for example, air, into and out of the apparatus. The disclosed apparatus may be used to mix particulate material, for example, mortar; react fluids with particulate material; coat particulate material, or simply convey particulate material. | 03-04-2010 |
