Title: Pneumoccoccal polysaccharide conjugate vaccine
Inventor: KNISKERN PETER J
IPC: A61K39/09
Filed: 1992-01-20
Abstract: A novel conjugate vaccine comprising partially hydrolyzed, highly purified, capsular polysaccharide (Ps) from Streptococcus pneumoniae bacteria (pneumococci, Pn) linked to an immunogenic carrier protein, is produced by a new process. The conjugate is useful in the prevention of pneumococcal infections. Vaccines comprising a mixture of from one to ten different pneumococcal polysaccharide-immunogenic protein (Pn-Ps-PRO) conjugates induce broadly protective recipient immune responses against the cognate pathogens from which the polysaccharide components are derived. Young children and infants younger than 2 years old, normally unable to mount a protective immune response to the Pn-Ps alone, exhibit protective immune responses upon vaccination with these Pn-Ps-PRO conjugates.

Title: Apparatus and methods for trace component analysis
Inventor: SIN CHUNG HANG
IPC: H01J49/04
Filed: 1991-08-28
Abstract: A method and apparatus for analyzing chemical species includes an ion source (2) at or near ambient pressure and a time-of-flight mass spectrometer which receives the ions, created at the ion source (2) through an ion supersonic jet forming device (5, 6). The ion source (2) creates ions from neutral molecules in the sample to be analyzed or serves to introduce already formed ions into the mass spectrometer vacuum chamber (11). The ion source can use any of the known techniques for ion creation, including a corona discharge (3) or a 63 Ni Be-ta ion source (22). The ions are created and are then in-troduced into the vacuum region (11) of the mass spec-trometer through a small orifice (6) which causes the stream of ions entering the vacuum region (11) to enter as a supersonic jet wherein the kinetic energy of each in-dividual ion falls within a narrow energy band. The ions are then repelled or drawn into the field-free flight tube of the mass spectrometer and separated and identified based on their mass-to-charge ratios.
