Title: Electroabsorptive asymmetrical fabry-perot modulator array for line printers
Inventor: NOCHEBUENA ROGELIO F
IPC: B41J2/465
Filed: 1994-09-19
Abstract: There is disclosed a line printing system of this invention which utilizes an array of asymmetrical Fabry-Perot light valves for simultaneously transferring all pixel information of one raster line onto a photoreceptor. The number of elements of the light valve array used in this invention is equal to the number of pixels on a raster line. The pixel information is applied to elements of the light valve array in a parallel format with information representing each pixel applied to one elemental light valve of the array. The array is illuminated by a wedge-shaped incident light beam forming a focussed line image. Depending on the information state of each pixel, each corresponding element will be activated to absorb incident light or left in its neutral state to reflect the light. Light reflected by neutral elements will be directed onto the photoreceptor. In this fashion, the photoreceptor simultaneously receives the pixel information for the entire raster line. In another mode, the elements will be activated to reflect the light beam and will be left in their neutral state to absorb the light beam.

Title: Combined virustatic antimediator (covam) treatment of common colds
Inventor: GWALTNEY JACK M JR
IPC: A61P31/16
Filed: 1992-11-18
Abstract: The common cold and related disorders such as influenza, acute sinusitis, acute otitis, and infectious exacerbations of obstructive pulmonary disease, are best treated by providing a combination of antiviral agents and antiinflammatory compounds to a patient infected with a cold or influenza virus. An antiviral agent and two antiinflammatory compounds given to a person infected with a cold virus simultaneously reduces the likelihood of a cold developing and the amount and duration of viral shedding, as well as substantially reduces the severity of individual cold symptoms and the overall number and severity of cold symptoms. Supplementing the activity of the combined antiviral and antiinflammatory agents with such compounds as antihistamines and alpha agonists results in suprisingly good nasal benefits. The combination therapy, termed COVAM therapy, is well tolerated and has no evidence of short-term toxicity.

Title: Process and apparatus for removal of unwanted fluids from processed blood products
Inventor: PAGE ROGER EDWARD
IPC: A61M1/02
Filed: 1993-09-01
Abstract: In the processing of a blood product to deplete the product of leukocytes, air can be introduced with the leukocyte depleted blood in a transfer bag.  This air is potentially harmful to the recipient of the processed blood product.  It is removed by providing a line between the transfer bag and a donor bag, from which the blood product is passed for processing, with the by-pass line including a hydrophobic filter which allows the passage of air but prevents the passage of processed blood product.  In this way, all the air can be removed from the transfer bag without affecting the quality of the processed blood products.  A similar arrangement can be used for removing other unwanted fluids from processed blood products.
