Abstract: This  invention  describes  a  retaining  device  for holding, guiding and self-actuated releasing of assembly and auxiliary assembly parts,  such as nuts,  bolts,  and rivets, in a device for pressing or attaching the parts to sheet metal, illustrated here with nuts as an example.  The retaining device is used to hold the nuts in a definite, stable position during their transport from a starting position to the working position.   It consists of two retaining catches that are pivotably mounted to the plunger so that they can be pivoted between a closed position in which they hold the nuts against the plunger, and an open position in which they release the nuts.   A restricted guidance element for the retaining catches ensures that during an outward thrust movement of the plunger,  the retaining catches remain in their closed position and will only be released to pivot into the open position after the plunger has reached the working position.

Granted: 2005-11-08
Abstract: Lipid-containing prodrugs are provided for treating viral infections duo to herpes, influenza, hepatitis B. Epstein-Barr, and varicella-zoster viruses, as well as cytomegalovirus and derivatives of antiviral agents. The compounds comprise phosphonoacids having antiviral activity which are linked, either through the phosphate group or carboxyl group of the  phosphonoacid, to one of a selected group of lipids. Phosphonoacetic acid and phosphonoformic acid are thus linked to phospholipids, glycerolipids, sphingolipids, glycolipids, or fatty acids. The compounds persist, after intracellular hydrolysis, as the antiviral phosphonoacids. The lipid prodrugs are effective in improving the efficacy of antiviral phosphonoacids by prolonging their antiviral activity following administration.

Abstract: To facilitate baking a frozen dough product in an oven having a rack formed of aligned bars, the dough product is formed over an oven-safe paper sheet which has a plurality of die-cut holes. This sheet serves as a baking substrate and obviates the need for a baking pan. The paper sheet is formed with the dough product, and the dough extends through the holes and locks the sheet to the dough. The end user may thus remove the frozen dough product together with the sheet from a backing perform and place the assembly on an oven rack for baking. As the dough thaws the crust will loose its stiffness. The sheet however, will prevent the more pliable crust from distending through the oven rack before the dough has become baked and rigid. The sheet forms a backing which restrains flow of the dough, while at the same time the holes permit the escape of gases from the bottom of the crust and ensure uniform baking. Furthermore, the holes allow direct radiant heating of the dough product through the paper sheet. The position and size of the holes may be adjusted to achieve desired uniformity of baking of the dough product. The finished baked dough product, such as dinner rolls or a pizza crust, may be removed from the oven with the sheet attached thereto, and the baked dough product may be served directly from the sheet.

Abstract: A method and apparatus (10) for inserting partitions (P) into a group of articles (A) is disclosed. The method includes combining articles, such as beverage containers, to form an article group (G) of predetermined configuration, including longitudinal rows of articles. The article group is conveyed toward a divider (11) disposed in the path of travel. The divider (11), which includes an angled end portion (16) that acts as a cam, separates the article group into article subgroups (SG). Once the article subgroups are transversely separated to a predetermined extent, a partition inserter (26) places a partition (P) between the article subgroups. The two subgroups are then recombined to affix the partition between adjacent articles. The recombined article group, including a partition, is then moved through the packaging machine to the next process step or simultaneously inserted into cartons.
