5556949 CAP-PHENANTHROLINE CONJUGATE FOR DNA CLEAVAGE Ebright Richard; Ebright Y W; Pendergrast P Shannon N Brunswick, NJ, UNITED STATES Assigned to Rutgers University A class of site-specific DNA cleavage agents comprising a sequence-specific DNA binding protein and a nucleolytic moiety attached thereto at an amino acid that is close to DNA in the specific protein-DNA complex, but that is not close to DNA in the non-specific protein DNA complex. These site-specific DNA cleavage agents cleave DNA at specific DNA recognition sites and have little or no non-specific DNA cleavage activity.
5558006 HEALTH BEVERAGE PLANT EXTRACTION APPARATUS Kuboyama Nobuyoshi STATES
Carlisle, UNITED
A health beverage is provided from plant, animal or mineral material that includes an ingredient beneficial to human health. The effective ingredient is extracted from the material by atomizing water in an ultrasonic tank. A blower is used to suck the atomized droplets through a canister containing the plant, animal or mineral material. The atomized droplets are then condensed in a cooling tank to a liquid form containing the healthful ingredient extracted from the plant, animal or mineral material.
5558774 AERATED HOT M E M B R A N E BIOREACTOR PROCESS FOR TREATING RECALCITRANT COMPOUNDS Tonelli Feruando A; Behmann Henry Dundas, CANADA Assigned to Zenon Environmental lnc
A wastewater feed containing an ultimate BOD/COD ratio >0.6 is well-suited for especially acclimated themaophific and/or caldo-active living micro-organisms ( hot cells ) which thrive in an autothermal aerobic (ATA) reaction zone having an ATA bioreactor (ATAB) operating at substantially ambient atmospheric pressure in combination with a MF or UF membrane filtration device from which a solids-free permeate may be withdrawn. This combination, of ATAB and membrane device is a membrane bioreactor (ATA MBR), which operates autothermally with a feed containing biodegradable organic materials having a BOD of at least 5,000 mg/L, preferably at least 10,000 mg/L (10 g/L) with a minor portion of municipal wastewater or domestic sewage. Operation of the ATAB, preferably in the thermophilic range from 45°C-75°C, with constant HRT from 1 to 12 days, is contingent upon maintaining a stable population of live hot cells. Such cells enhance the biokinetics of degradation and allow operation of the ATAB at higher COD loading and a lower concentration of TSS, than would be possible at a lower temperature. A surprisingly high membrane productivity allows production of much less sludge to be disposed of outside the system, than would have to be disposed of with a conventional mesophilic reactor in normal operation with a HRT of less than 24 hr. A combination of an MP MBR with an ATA MBR is highly effective when the MPB produces high BOD concentration mixed liquor for destruction by the ATAB.
5558834 DEVICE AND METHOD OF SEPERATING AND ASSAYING WHOLE BLOOD Chu Amy H;Stover Lon Granger, IN, UNITED STATES Assigned to Bayer Corporation An improved device and method of separating the cellular components of whole blood from plasma or serum and assaying the plasma or serum for a predetermined soluble constituent are disclosed. The device includes a filter pad, that separates the cellular components of whole blood from the serum or plasma, and a test pad, that assays the serum or plasma for a predetermined soluble constituent. The filter pad effectively separates and retains cellular components of the whole blood sample, thereby eliminating assay
