Abstract: A tray insert for securing fluid reaction members in a handling tray includes a body having first and second major surfaces, first and second ends, sliding members disposed on the first and second ends, which are configured to engage with a plurality of slots formed in the handling tray, and a first plurality of sockets extending into the first major surface, which are spaced from one another to receive and support a plurality of fluid reaction members. The tray insert is configured to hold the fluid reaction members in a suspended state, which prevents them from coming into contact with each other or a surface of the handling tray.

Abstract: The present invention discloses an article orienting apparatus for use in a printing process. The apparatus includes a power roller inclined at an acute angle to the article path for wrappingly receiving an article. The article is moved from a first orientation to a second orientation. The apparatus further includes a second drum for inverting the moving articles.

Abstract: A turning and orienting device can receive an article such as a folded paper, envelope or the like, and can turn the article and/or rotate the article for re-orienting the article. An annular plate is constantly rotating, and a central plate in the same plane is fixed. Spring urged balls can receive the article therebeneath to urge the article against the plates; therefore, the portion on the stationary plate will be held still while the portion on the rotating plate will be moved in a circular path. By adjusting the location of the balls, and varying the point at which the .article is stopped, virtually any combination of turning and rotation of the article can be accomplished.

Abstract: Articles such as mail are rotated 90.degree., aligned at one edge, and tabs applied to the edge and wrapped around the edge. The article is carried on a belt, and a stop halts forward movement of the article as the article is received under a pivot ball and a drive ball that holds the article against the belt. The driving force causes the article to rotate about the pivot until the article is free to move further on the belt. Angled belts receive the article and urge it against an alignment fence. A tab is dispensed onto the article, and a twisted belt provides a warped surface for wrapping the tab around the edge of the article. Pressure belts press the tab firmly into position.

Abstract: In a circuit board installation in which circuit boards are slidably mounted in opposed guide rails of a rack in a cabinet, an efficient and relatively inexpensive flat cooling module is slidably mounted in opposed guide rails between two circuit boards. The cooling module comprises a pair of flat side walls spaced apart and sealed together around their edges to form a sealed chamber, an inlet port in the cooling module connected to a source of pressurized cooling fluid and, in each of the side walls, mutually spaced orifices in which nipples may be fitted and through which pressurized cooling fluid is directed towards components of the adjacent circuit boards.
