IPC: G06T15/40
Filed: 1991-03-15
Granted: 2001-10-16
Abstract: A polygon sort engine (100) including first and second apparatus for sorting. The first apparatus for sorting receives planar, externally convex polygon vertices (102) from an external polygon tiling engine. This includes points and lines. The state machine (156) on the second apparatus for sorting interfaces with the polygon tiling engine and a raster engine in a graphics pipeline. It provides a control signal which determines when the first apparatus for sorting will receive the next polygon. The second sorting appartus also controls whether the polygon is stored in the PING or PONG memory (184, 186). For example, as the state machine (156) is controlling the sorting of the current polygon into the PING RAM (184), the state machine (156) will also be controlling the loading of the previous vertices and the PONG RAM (186) into the raster engine.

Granted: 2000-09-19
Abstract: The invention relates to a peptide from human blood, designated as hPTH-(1-37), the structure of which was elucidated for the purpose of the diagnostic, medical and commercial utilization thereof. The isolation of a fragment hPTH-(38-84) proves the existence of the hPTH-(1-37). A removal of amino-terminal amino acids from the hPTH fragment-(1-37) reduces its biological activity. The hPTH-(1-37) circulating in the blood is identical with the synthetic reference substance hPTH-(1-37), however not with fragments such as hPTH-(1-33), hPTH-(1-34) or hPTH-(1-38). The molecule form hPTH-(1-37) has been proven by mass spectrometry (plasma desorption method). A different biological activity and differences in the three-dimensional peptide structure of the hPTH fragment-(1-37) in comparison to other hPTH fragments furnish evidence of that this fragment is the preferential natural peptide of the parathormone family which should be used for the treatment of diseases of the parathyroid, circulatory system, respiratory system, male genital organ and kidneys.

Inventor: GARRY ROBERT F JR
IPC: C12N5/078
Filed: 1991-05-20
Granted: 2006-09-19
Abstract: The present invention relates to purified preparations of a novel retrovirus, to methods of diagnosis and treatment of Sjogren's syndrome, novel cell lines, and model systems for the study of autoimmune diseases and AIDS. It is based, in part, on the discovery of a novel retrovirus which is antigenically similar to human immunodeficiency virus but which appears to comprise a functionally distinct reverse transcriptase. According to the present invention, Sjogren's syndrome as well as other autoimmune diseases, may be diagnosed, and their clinical course may be monitored, by demonstrating the presence of anti-retroviral antibodies and/or measuring the levels of such antibodies.  Alternatively, Sjogren's syndrome or other autoimmune diseases may be diagnosed or monitored by directly or indirectly demonstrating viral particles in the cells of a patient.  Furthermore, according to the invention, Sjogren's patients who have been found to exhibit retrovirus or anti-retroviral antibodies may be treated with agents known to be useful in the treatment of retroviral diseases, including but not limited to, agents which interfere with reverse transcriptase function, such as, for example, nucleoside analogues (e. g. zidovudine or dideoxyinosine).

Title: Method for the use of gas assistance in the molding of plastic articles to enhance surface quality
Inventor: HENDRY JAMES WATSON
IPC: B29C49/06
Filed: 1991-11-01
Granted: 1996-08-06
Abstract: A method of gas-assisted injection molding in which: 1) a first amount of plastic is injected into an article-defining cavity of a mold so that it flows therein; 2) a second amount of plastic continues to be injected into the cavity simultaneous with the injection of a charge of pressur-ized gas wherein the pressurized gas pre-vents the flow of plastic in the cavity from stopping; and 3) the charge of pressurized gas continues to be injected after the sec-ond amount of plastic is injected to distri-bute the total amount of molten plastic resin in the cavity. The ratio for the first amount of plastic to the total amount of plastic required for the preparation of the article is in the range of .2 to .7. Also, the pressurized gas has a pressure between approximately 1000 psi and 5000 psi. These steps prevent imperfections on the exterior surface of the plastic article. The gas charge is maintained under pressure within the article until the article has set up in the article-defining cavity. Finally, the gas pressure is relieved in the article and the finished article is removed from the mold. The method is particularly useful in molding articles having a relative large cross-section.

Abstract: Disclosed are methods and compositions for the suppression of expression of the neu oncogene, as well as suppression of neu oncogene-mediated transformation, tumorigenesis and metastasis. The method disclosed involved introduction of adenovirus early 1A gene-(the E1A gene) products into affected cells. These products, which are preferably introduced by transfection of the E1A gene into affected cells, serve to suppress neu gene expression as measured by a reduction of p185 expression. Furthermore, the E1A gene products surprisingly serve to suppress the oncogenic phenotype, as indicated by a reduction in cell growth, growth in soft agar, as well as tumorigenic and metastatic potential in vivo. The inventors propose that E1A gene products, or derivatives therefrom, may ultimately be employed as treatment modalities for neu-mediated cancers, such as cancers of the female genital tract and breast.
