Abstract: A new composition of matter for a diamidodiol and a method for preparing the diamidodiol. The exemplary diamidodiol has the formula C15H30N2O4 and is prepared by reacting a first quantity of 2-amino-2-methyl-1-propanol with a second quantity of a di-substituted malonyl dichloride (i.e., diethylmalonyl dichloride), preferably in ethyl acetate as solvent. A tetraamido macrocycle is prepared from the diamidodiol in two steps by oxidizing the diamidodiol to form a diacid followed by coupling using a known procedure of the diacid with an aryl diamine (e.g., 1,2-diaminobenzene) to yield the tetraamido macrocycle.

Abstract: An improved cleaning composition is provided for shower and tub surfaces which is of the "shower rinsing" type, requiring no scrubbing, wiping, or immediate rinsing. The composition comprises:(a) a glycoside surfactant, the total amount of said surfactant being present in a cleaning effective amount;(b) a chelating agent, said chelating agent present in an amount effective to enhance bathroom soil removal in said composition; and(c) the remainder, water. A solvent such as isopropyl alcohol may also be added. The employment of a glycoside surfactant, especially one having an HLB value of greater than 13, remarkably improves the performance of such a shower rinsing composition both with respect to surface appearance streaking and filming and also bathroom soil and soap scum removing ability.

Abstract: A concentrated, dilutable cleaning composition is provided which comprises a microemulsion comprising an oil phase of which the "oil" is a nonionic surfactant, a predominant aqueous continuous phase, a polar organic solvent coupling agent, and a combination of surfactants different from the surfactant oil phase as the dispersing agent facilitating formation of said microemulsion, the cleaning composition dilutable with water for use as an all purpose cleaner and characterized by exhibiting the feature of blooming upon such dilution even in the absence of a lipophilic oil (or solvent). The blooming phenomenon is associated with the formation of a liquid crystal dispersion, which liquid crystal state is found to greatly enhance the cleaning effectiveness of the composition. In one aspect of the invention, one of the dispersing agent surfactants is a cationic surfactant which may be a quaternary ammonium compound capable of imparting an antimicrobial effect to the composition.

Abstract: A multi-well container (10) is provided in which a greater number of wells may exist than heretofore possible while still maintaining a standard multi-well plate tube array format and footprint. The multi-well container (10) is comprised of a rectangular array of tubes (12) in standard tube format held together by an integrally fashioned plate portion (16). The tubes (12) are subdivided by partitions or septa (14) which extend the height of the tubes (12). Each septum (14) may constitute a single wall or may be comprised of any number of fins (32) which are integral with internal tube surfaces (28). In a symmetrical design with four such fins (32), the fins (32) radiate at angular intervals of 90 degrees from a common central axis (34) with which all four fins (32) are integral. Thus, the septa (14) serve to compartmentalize each tube (12) into symmetrical quadrants of four smaller wells or sub-tubes (30).

Abstract: Adjustable balance weighting systems (10 and 110) are provided for adjusting the weighting and balance of golf clubs of either the "iron" or the "wood" types.
