Abstract: A jogging apparatus 22 has motor 24 mounted within a support frame 20. Motor 24 has a motor shaft 28 to which is connected hub 30. Projecting outwardly from motor hub 30 along an axis parallel to, but eccentrically offset from, the axis of motor shaft 28 is eccentric pin 34. Slotted link 32 slidably engages slot pins 36 and 38 in transverse slots 42 and 44 respectively of slotted link 32 for transverse movement of slotted link 32. Slotted link 32 also has an orthogonal slot 46 generally perpendicular to transverse slots 42 and 44. Eccentric pin 34 is slidably engaged within orthogonal slot 46 such that as motor shaft 28 is rotated, the rotational motion of shaft 28 is converted into the side-to-side motion of slotted link 32. Eccentric pin 34 projects somewhat beyond the outer surface of slotted link 32 and typically terminates in enlarged head 57. Enlarged head 57, with respect to orthogonal slot 46, describes an up and down movement within slot 46, as motor shaft 28 rotates.

Abstract: A method for diagnostic or prognostic monitoring of premalignant or malignant conditions of human secretory epithelia, particularly colonic epithelia, by determining the extent of expression of a .beta.1-3N-acetylglucosaminyltransferase is described. Associated with the expression of a wide variety of carbohydrate antigens in adenocarcinomas is the induction of .beta.1-3N-acetylglucosaminyltransferase in epithelial cells. This enzyme is not found in normal, healthy adult colonic epithelial cells and thus indicates a novel and potentially sensitive method for screening the disease status of individuals.

The outer surface of the jacket having vent panels attached to front and rear panels which create accessible, upwardly extending vent panel pockets. Inside each vent panel pocket is a detachable flexible informational display panel which can be stored inside each pocket and hidden from view. When the situation arises, the flexible informational display panel can be repositioned and extended downwardly below the vent panel pocket and used to display information.

Abstract: A lightweight, pre-cast, reinforced, module used to build a structurally engineered retaining wall system. Each module has a panel with a front and rear surface with at least one horizontal reinforcing rod. In the preferred embodiment, a portion of each rod horizontal transverse an integrally attached flange located at each opposite end of the panel. On the outside surface of each flange, there is a recess across which a portion of each reinforcing rod is exposed to be subsequently surrounded by concrete of a poured-in-place reinforced column. A horizontal row of adjacent modules is positioned on a constructed, reinforced footing. The front surface of each module is exposed and each flange is positioned opposite to a flange located on an adjacent module with a column space created between opposite flanges. Alignment elements are attached to the upper surface of each flange and successive horizontal rows of modules are then positioned above until the desired height is achieved.
