International Classification:

C11D 175

US Classification:

510181

Abstract:

The invention provides an aqueous, hard surface cleaner with significantly improved residue removal and substantially reduced filming/streaking, said cleaner comprising: (a) an effective amount of at least one organic solvent with a vapor pressure of at least 0. 001 mm Hg at 25. degree. C. , and mixtures of such solvents; (b) an effective amount of at least one semi-polar nonionic surfactant, said surfactant having the structure: ##STR1## wherein R. sup. 1 is C. sub. 5-20 alkyl, R. sup. 2 and R. sup. 3 are both C. sub. 1-4 alkyl, ##STR2## or --(CH. sub. 2). sub. p --OH, although R. sup. 2 and R. sup. 3 do not have to be equal, and n is 1-5, and p is 1-6; (c) an effective amount of a buffering system which comprises a nitrogenous buffer which will result in a pH of greater than 6. 5; and (d) the remainder as substantially all water.

Appl. No.:

7/827567

Inventors:

Gary A. Robinson - Lafayette CA

International Classification:

A63F 100

US Classification:

273303

Abstract:

Disclosed is a deck of rectangular playing cards usually having two substantially parallel long edges and two substantially parallel short edges, substantially all cards in the deck having a front symmetrically designed with respect to both short edges, to minimize cheating by signalling with asymmetric cards. The front is usually designed to be symmetrical with respect to the short axis, and preferably the long axis as well, of each card. Generally, the deck includes at least 52 cards, thirteen in each of the four standard suits, spades, hearts, diamonds, and clubs. Frequently the symmetry is obtained by the use of at least one "double-pip" in the front of the card. A "double-pip" consists of a single pip of a suit having asymmetric pips, the pip placed generally end to end with its mirror image to create a single symmetric rather than asymmetric pip of the suit. Sometimes "reversed pips" are also used. A "reversed pip" is merely a pip placed upside-down on the front rather than right side up.
