Title: Opthalmic lens inspection method and apparatus
Inventor: JAMES A EBEL
IPC: G01M11/02
Filed: 1993-12-17
Granted: 1999-12-01
Abstract: Disclosed is an ophthalmic lens inspection method and apparatus comprising a camera to capture an image of an ophthalmic lens which has been illuminated by a light source. Location and intensity at each camera pixel is converted to an electrical quantity which is then transferred and stored in a memory. A computer containing instructions for comparing the intensity and location values of the pixels starts near the center of the receptor field and continues toward the edge of the field until an intensity deviation is encountered. By evaluating the pixels containing intensity variation, an outline of the lens edge is attained. An annulus is generated enclosing the actual lens edge. All the pixels are changed from an absolute intensity value to a gradient value, represented by two transition edges. Feature extraction is performed to locate defective pixels and place them into groups. Once the groups have been determined each is given a score based on the number, type and severity of the defective pixels placed into that group. From that, a weighted score can be given to the entire lens and the lens either passes or fails.

Abstract: Isoandrographolide-19-propionate for treatment of non-alcoholic_ fatty liver disease (NALFD) relates to the compound isoandrographolide-19-propionate (IAN-19P) and pharmaceutically acceptable salts thereof. The compound is synthesized by reaction of isoandrographolide with anhydrous propwmc acid m the presence of N,N'- dicyclohexylcarbodiimide and 4-dimethylaminopyridine. In vitro testing shows that isoandrographolide-19-propionate has lower toxicity than andrographolide, but has significantly high activity at a concentration of 50 ~tM. IAN-19P produced normal triglyceride levels and significantly lowered lipoperoxide formation in palmitate-oleate induced steatotic HepG2 cells, and also lowered AL T leakage from the treated cells.

Title: Fracturing Utilizing an Air/Fuel Mixture
Inventor: WILSON EDWIN
Filed: 2017-12-14
Abstract: A method of producing subterranean fractures in geologic formations for the extraction of hydrocarbons includes flowing an air and fuel mixture into a well hole. The well hole may then be sealed with a packer plug creating a compression chamber with the air and fuel mixture. A liquid, such as water, may be pumped into the well hole to create pressure in the compression chamber. The build-up of pressure eventually causes auto-ignition of the air and fuel mixture which fractures the formation. The water may then rush into the compression chamber which thermally shocks the area causing additional fractures. The water may vaporize to steam and thoroughly disinfect the well hole eliminating the need for added biocides. Fig 1
