Title: Peptide vaccines and methods relating thereto
Inventor: KAHN MICHAEL
IPC: C07K14/16
Filed: 1995-03-15
Abstract: There are disclosed peptide vaccines and methods related thereto for generating a protective immune response in warm-blooded animals. The peptide vaccines comprise a conformationally reverse-turn mimetic, a T cell stimulatory peptide, and a cleavable linker covalently joining the conformationally constrained reverse-turn mimetic and the T cell stimulatory peptide. The confromationally constrained reverse-turn mimetic mimics the three-dimensional structure of an antigenic determinant of a native pathogenic protein and is capable of binding to a B cell. Upon binding to a B cell, the peptide vaccine is internalized and the T cell stimulatory peptide is released from the conformationally constrained reverse-turn mimetic by cleavage of the cleavable linker. The T cell stimulatory peptide is then expressed on the surface of the B cell in association with class I or II MHC molecules, thus inducing T cell activity and generating a protective immune response.

Abstract: Balanced injection molding in a multi-cavity mold of a plurality of ties having a uniform maximum thickness between opposite broad sides of the tongue of the tie is accomplished by providing mold pieces in which the relative dimensions of projections for forming ratchet teeth on the tongue of the ties in different mold cavities are non-uniform such that when plastic material is injected into the mold cavities, the injected plastic material flows through the different mold cavities at respective flow rates that cause the mold cavities to be completely filled approximately simultaneously with the injected plastic material. In making the mold pieces, the dimensions of the projections initially are larger than required for forming ratchet teeth of a preferred dimension. After measuring the extent to which the different cavities are filled, the relative dimensions of the projections are adjusted such that the projections for at least one of the mold cavities are of a dimension required for forming ratchet teeth of the preferred dimension and/or such that the projections for at least one the mold cavities are of a dimension larger than required for forming ratchet teeth of the preferred dimension and the projections for at least another of the mold cavities are of a dimension smaller than required for forming ratchet teeth of the preferred dimension.

Title: Method for fracturing and gravel-packing a well
Inventor: JONES LLOYD GARNER
IPC: E21B43/26
Filed: 1997-07-14
Abstract: A method for gravel-packing an interval within a cased wellbore wherein perforations in the well casing are cleaned of any plugging materials before placement of the gravel (e.g., sand). A screen having alternate flowpaths thereon is lowered adjacent the perforated casing and a clear fluid (e.g., clear fracturing gel) is pumped through the perforations into the formation.        The gel cleans the perforation of any plugging material and fractures the formation. A gravel (e.g., sand) slurry is then pumped into the annulus and through the perforations to deposit sand in the fracture, the perforations, and the annulus around the screen. If a sand bridges) forms in the annulus, the alternate flowpaths will deliver the slurry to all levels within the annulus insuring good distribution of sand across the interval.

Inventor: STEARNS STANLEY D
IPC: G01N30/64
Filed: 1997-08-25
Abstract: A method and apparatus are set forth which enables a gas chromatographic column output to be connected with a pulse discharge chamber in which chemically bound chlorine in volatile organic or inorganic samples is measured. A spark discharge is formed in the chamber to ionize and excite helium molecules to a metastable state. In turn, that transfers excitation to a trace of krypton gas in the chamber which is ionized, and the ionized krypton then preferentially binds with chemically bound chlorine. The latter binding occurs with the liberation of a photon centered at about 222 nanometers thereby defining a spectral region of interest which is measured by a photomultiplier tube to quantify chemically bound chlorine.
