20090001011 | GRAVITY FLOW FILTER - A gravity-fed carbon block water filter in one embodiment includes a filter block comprising multiple sub-blocks each comprising filter media walls surrounding and defining a cavity for receiving fluid. Each of the sub-blocks is connected to at least one other of the sub-blocks by filter media of which the filter block is made. In one approach, the filter media includes about 20-90 wt % activated carbon, and about 5-50 wt % binder. In another approach, a lead concentration in a final liter of effluent water filtered by the filter is less than about 10 μg/liter after about 151 liters (40 gallons) of source water filtration, the source water having a pH of 8.5 and containing 135-165 ppb total lead with 30-60 ppb being colloidal lead greater than 0.1 μm in diameter. A gravity-fed water filter in other embodiments has no specified shape but achieves a FRAP factor of about 350 or less. | 01-01-2009 |

20120226291 | Surgical Ligation Clip and Applicator Device - A surgical tissue ligation clip and an applicator device for delivery of multiple ligation clips is provided. The surgical ligation clips have first and second leg members joined by a resilient hinge at one end and a deflectable hook member and a locking element on the opposite end. The surgical tissue ligation clip has a proximal tissue shield that prevents tissue from being pinched at the hinge, and/or a distal tissue shield that prevents tissue from being pinched between the hook member and locking element and interfering with securely closing the ligation clip for implantation. A minimally invasive applicator for the surgical ligation clip is provided for delivering individually arranged ligation clips in line, incising target tissue and delivering a plurality of surgical ligation clips at the tissue site. | 09-06-2012 |

20080225265 | METHOD AND APPARATUS FOR FINDING MACROMOLECULE CRYSTALLIZATION CONDITIONS - A system and method for determining macromolecule crystallization conditions by measuring the polarization anisotropy of a fluorescent probe attached to the macromolecule in solution as a function of a variation in crystallization conditions. In one exemplary embodiment, the concentration of the macromolecule material is varied and the polarization anisotropy as a function of concentration gives an indication of the proximity to crystallization conditions. A pulse illumination system with time gated detection is disclosed to isolate fluorescence response from excitation to reduce noise due to scattered and reflected light. A microassay system is disclosed to allow a complete 96 condition screen with less than 1 micro-liter of solution. | 09-18-2008 |
