Abstract: In an automatic wash, a control unit operates a boom arm around a vehicle in a bay by moving a bridge along a lengthwise vehicle orientation, moving a trolley on the bridge along a widthwise vehicle orientation, and rotating the boom arm about the trolley. The boom arm is coupled to a mount which is flexibly coupled to the trolley such that boom arm impact displaces the mount and the trolley. The displacement may be two-dimensional and/or angular. In response, the control unit determines whether an impact has occurred by comparing the data to a baseline. If there is an impact, the control unit relocates the boom arm and may continue the wash process. If a sufficient force impact occurs that the control unit cannot correct, the boom arm may disengage from the mount which may trigger a breakaway sensor and cause the control unit to abandon the wash.

Abstract: Adhesive formulations having acrylate monomer or methacrylate monomer, or mixtures thereof, and having a reducing agent and an initiator (e.g., peroxide). The formulations may include a chelating agent solution to improve storage stability and other properties. Further, the mole ratio of the initiator to the reducing agent may be adjusted to control weight loss of the adhesives during cure. Polyvinyl acetate or its derivatives may also be employed in the adhesive formulations to reduce weight loss during cure. Moreover, certain embodiments of the formulations include a toughening-agent copolymer having a glass transition temperature (of at least one domain) that is lower than ?50° C. (?58° F.). These toughening-agent copolymers may be added to the adhesive formulations to improve impact strength and other properties of the cured adhesives at lower temperatures, e.g., ?40° C. (?40° F.), while maintaining performance of the cured adhesives at higher temperatures, e.g., 82° C. (180° F.).

Abstract: An adhesive comprising a combination of high molecular weight acrylic and/or methacrylic esters, which become co-polymerized with low molecular weight acrylic and/or methacrylic esters, and advantageously polymers, such as impact modifiers including graft co-polymer (core-shell and non core-shell) impact modifiers, carboxylic acids, elastomers, and sulfur bearing compositions, such as chlorosulfonated polymers.

Abstract: A spray aperture disk designed for insertion into a column liner of an electron microscope having a substantially circular shape, a plurality of tabs or extensions located on the circumferential periphery of the disk and a small central aperture. The disk is inserted into the tapered end of a column liner and then deformed by a tool which pushes the disk into position within the column liner. The disk may be removed by inserting a rod of appropriate length and width into the column liner and pushing the disks out. The disks are self centering and require no separate carrier. The disks are made from inexpensive materials and are disposable.
