Abstract: INSTANT BINGO GAME ABSTRACT OF THE DISCLOSURE A bingo card for playing at an instant bingo game comprises a first area in which bingo numbers are printed and covered by an opaque layer which can be scratched away to individually reveal each bingo number in turn. The card further includes four separate bingo playing areas each of which is in the form of a bingo card with the numbers printed thereon in conventional manner. On top of each of the second playing areas is applied a translucent coat of a scratchable material which is pigmented so as to modify the appearance of the underlying color of the area. The playing area can therefore be marked in relation to those numbers appearing on the first area simply by scratching away the translucent layer to provide a visual distinction. The game card is simple and effective and requires printing of the playing numbers only once as they can be viewed through the translucent layer.

Title: Method of making fluorine/boron doped silica tubes
Inventor: CARPENTER NORMAN W
IPC: C03B37/028
Filed: 1992-11-23
Abstract: Abstract of the Disclosure Disclosed is a method of forming a glass tube doped with boron and fluorine.  A B2O3-doped tubular porous preform is heated, and a fluorine-containing gas is flowed into its aperture.  The temperature is sufficiently high to cause the fluorine-containing gas to decompose and form fluorine which dopes the preform.  Also flowed into the aperture is a sufficient amount of BF3 to prevent fluorine from reacting with the B2O3 in the porous preform and forming a B2O3-depleted region near the aperture surface. The particles are then fused to form a fluorine-containing dense glass tube.

Patent CA-2086097-A1 (CA)
Inventor: HUNTER ROBERT L
IPC: A61K39/39
Filed: 1991-06-27
Abstract: The present invention comprises adjuvants which, when admixed with an antigen and administered into a human or animal, will induce a more intense immune response to the antigen than when the antigen is administered alone. In many cases, the adjuvant that is described as the present invention will increase overall titer of antibodies of a specific isotype which are specific for the antigen. For example, in mice, when the adjuvant of the present invention is admixed with a conventional antigen, the isotype that is induced in the mouse is changed from a predominantly IgG1 isotype to the more protective IgG2 isotype and, in some cases, IgG3 isotype. Thus, by practicing the present invention, one can improve the overall protective effect of conventional vaccines.

Abstract: ABSTRACT OF THE DISCLOSURE    Business forms having labels integral with the sheets there of (rather than riding piggyback thereon) are produced by applying a strip of transfer tape to only a portion of the second face of a sheet, with the adhesive of the transfer tape contacting the sheet, so that sheet material surrounds the transfer tape strip completely.  Then a label is die cut from the first face of the sheet, preferably after the transfer tape is applied, within the area of the sheet overlying the transfer tape strip, without cutting the transfer tape backing.  Indicia is at some point printed on the first face of the sheet. The label may be readily removed, with the adhesive from the transfer tape sticking to the label while the backing of the transfer tape remains in place. The strip of transfer tape is cut from a web, and then is transported with the adhesive face outward by a vacuum cylinder, until it move- into contact with a moving web.  The web is ultimately formed into individual business forms, which may be multi-ply.
