    Abstract: A support frame for a drawer-type dishwasher includes a top section and opposing side sections formed from a plurality of support members which define an open lattice work and establish a cavity for a slidable dishwasher drawer. The support frame also includes first and second rail supports that are provided on respective ones of the opposing side sections. The first and second rail supports are designed to support corresponding first and second extensible rails which, in turn, support the wash tub for movement relative to the frame. In addition, the support frame includes lid support elements for a mechanism that provides shifting of a lid member relative to the wash tub.

    Abstract: A corrosion-inhibited antifreeze composition is disclosed. Specifically, the antifreeze composition comprises a major portion of a liquid alcohol freezing point depressant and a minor portion of at least one hydroxyl-substituted aromatic carboxylic acid having the hydroxyl radical disposed proximate to the carboxylic radical. The above described acid is employed as a corrosion inhibitor. Other conventional corrosion inhibitors may be employed in conjunction with the acids.In another embodiment, the present invention relates to a process for inhibitig the corrosion of metals present in the cooling system of an internal combustion engine which comprises intimately contacting the metal surface to be inhibited against corrosion with the antifreeze composition described above. Most preferably, the target substrate is high lead solder.

    Abstract: It has been surprisingly discovered in accordance with the present invention that when 1,3-dioxolane is reacted with formaldehyde in the presence of an organic peroxide and an ionizable, at least sparingly soluble metal salt, the reaction preferentially involves an addition of the formaldehyde to the 2-methylene group of the 1,3-dioxolane with only minor reaction with the 4-methylene and 5-methylene groups of the 1,3-dioxolane whereby the reaction product that is formed contains significant quantities of 2-hydroxyalkyl-1,3-dioxolanes. 2-Hydroxyalkyl-1,3-dioxolanes are hydrolyzed with comparative ease to ethylene glycol and the corresponding glycol aldehyde (CHO--CH.sub.2 --OH). The glycol aldehyde in turn can be catalytically hydrogenated to form additional quantities of ethylene glycol.
