Abstract: The invention provides effective analogs of the active GLP-1 peptides, 7-34, 7-35, 7-36, and 7-37, which have improved characteristics for treatment of diabetes Type II. These analogs have amino acid substitutions at positions 7-10 and/or are trun-cated at the C-terminus and/or contain various other amino acid substitutions in the basin peptide. The analogs may either have an enhanced capacity to stimulate insulin production as compared to glucagon or may exhibit enhanced stability in plasma as compared to GLP-1 (7-37) or both. Either of these properties will enhance the potency of the analog as a therapeutic. Analogs having D-amino acid substitutions in the 7 and 8 positions and/or N-alkylated or N-acylated amino acids in the 7 position are particularly resistant to degradation in vivo.

Title: Scarfing method and apparatus
Inventor: SHOWALTER MICHAEL S
IPC: B23K7/08
Filed: 1992-12-02
Abstract: A thermochemical scarfing method and apparatus are disclosed which allows a greater diagonal standoff distance from the metal workpiece during preheating. The method includes preheating the end of the metal workpiece, and then scarfing the workpiece by directing a scarfing oxygen stream onto the workpiece at an acute angle and while moving the workpiece past the oxygen outlet port. The preheating step includes generating a high speed stream of oxidizing gas and a concentric stream of fuel gas coaxially about the central stream, so that the momentum of the central stream is maintained. As a result, the effective flame heating distance may be extended, and the manifold and head assembly which supports the preheating gas nozzles may be moved back from the workpiece a significant standoff distance so as to avoid damage from dislodged molten metal slag.

Title: Vehicle lane position detection system
Inventor: MATHUR BIMAL P
IPC: G05D1/02
Filed: 1993-03-01
Abstract: ABSTRACT OF THE DISCLOSURE   A low cost, real time vehicle lane position detection system is provided for determining and maintaining the position of the vehicle on a highway. The system comprises an image sensor mounted on the front of an automotive vehicle and an integrated processor for performing real-time lane mark detection. The sensor/processor system identifies highway lane marks on the detector image plane by using a nonlinear resistive network for detecting A line detection algorithm, such as the Hough transform, is used to determine the lane marks from the outliers on the image plane. Because the expected lane position can be determined in advance, an added degree of signal-to-noise discrimination is achieved by providing feedback to the processor for outlier detection. The position of the vehicle in the lane is determined and tracked from the position of the detected lane marks on the image plane given the sensor position and optical geometry.
