Clasificación Internacional G11B 7/00 Nº de solicitud PCT/US1989/005135 Solicitante EASTMAN KODAK COMPANY Inventor/a BARNARD, James, Arthur

A single laser system utilizes a grating (12) to provide a shifted beam and a nonshifted beam which are directed through a polarized beamsplitter (14) in the nonsplitting direction. The beams are directed through a 1/4 wave plate (24) by means of a folding mirror (22). The beams (34) from the 1/4 wave plate (24) are focused onto the recording surface of a disk (28) to generate a write spot (30) and a DRAW (direct read after write) spot (32). The DRAW spot (32) is positioned behind the write spot (30) at a distance ot n+1/2 bits. Reflections from the DRAW spot (32) are collimated back through the 1/4 wave plate (24) onto the folding mirror (22). The folding mirror (22) directs the collimated DRAW verify spot to the polarized beamsplitter (14) where it is reflected through a lens (16) to a DRAW spot photodetector (20) for detection. In a like manner, read reflections are directed back to be focused on a read photodetector (18).

Clasificación Internacional F16K 5/18 Nº de solicitud PCT/US1991/002957 Solicitante JOHNSTON PUMP/GENERAL VALVE, INC. Inventor/a SMITH, Gordon

Self supporting non-lubricated retractable seal double block and bleed plug valve wherein an improved plug configuration provides direct bearing surface support (50) for the plug along at least a portion of the radial surface of the plug. The remaining radial surface of the plug may be optionally relieved (44) to avoid scuffing the swept seating area of the interior valve body surface. By utilizing the novel plug configuration for direct plug bearing support, the present invention obviates the need for a lower trunnion and does away with the need for high load-bearing bushings. In all other respects, the operation of a plug valve, utilizing the plug of the present invention remains substantially the same as it would be for a prior art plug valve. In fact, it is possible to substitute a novel plug configuration of the present invention for a prior art plug configuration for retrofitting existing valves of the type herein disclosed.

9.WO/1991/016924ENHANCING THE ASSOCIATION OF EXOGENOUS PEPTIDES WITH CLASS I MHC MOLECULES ON IMMUNE SYSTEM CELLS

WO - 14.11.1991

Clasificación Internacional A61K 38/17 Nº de solicitud PCT/US1991/003082 Solicitante THE DANA-FARBER CANCER INSTITUTE Inventor/a ROCK, Kenneth, L.

The present invention provides a method for enhancing the association of exogenously prepared polypeptides with class I MHC molecules on the surface of antigen presenting cells to thereby sensitize the target cells for class I MHC-restricted cytotoxic T cell response. The method involves obtaining the polypeptides of interest and presenting the polypeptides to the appropriate antigen presenting cells in the presence of an elevated level of free β₂-microglobulin. The method of the present invention can also be used to prime naive populations of T lymphocytes for antigen-specific class I MHC-restricted cytotoxic T cell response with exogenous polypeptide and is useful in both in vitro and in vivo applications. A new use for purified β₂-microglobulin as an adjuvant for synthetic polypeptide vaccines is also provided. In vivo immunization with the synthetic peptides and free β₂-microglobulin can elicit an antigen-specific CTL response as strong as that produced with endogenously synthesized antigen.
