Abstract: A biogas generator employs an anaerobic digestion process to convert organic waste material within a sealed reservoir to a biogas. A solar thermal panel connected to the reservoir heats a fluid traveling through a conduit, which is connected to a heat exchanger within the reservoir. The heated fluid travels through the heat exchanger and heats the waste material to facilitate the anaerobic digestion process. Solar cells produce electricity to operate one or more pumps that pump the heated fluid through the conduit, and pump the waste material and the generated biogas, into and out of the reservoir. A rotating lid structure has elongated agitators which extend into the reservoir.

Abstract: A deck of rock, paper, scissors playing cards and methods of play therewith are disclosed. The deck has fifty-two cards including four wild cards identified as little sister cards and little brother cards, and forty-eight cards including fourteen paper cards, fourteen rock cards, fourteen scissor cards, two crumpled paper cards, two broken rock cards, and two broken scissors cards. Each of the cards has a point value. The associated method includes playing the cards against each other wherein the cards have a hierarchy based on the pictorial. The hierarchy determines the winner of each game. The cards having point values for determining the points awarded for each card.

Abstract: A circuit module that contains a planar array of chips has an improved fin assembly that transfers heat to a liquid coolant that is circulated through the fins in a single pass so that there is a tendency for the upstream edge of the fins to run cold and the downstream edge to run hot. The module can be immersed in the coolant. A shroud on the fins confines the coolant flow to channels defined by the fins, the shroud, and the base of the fins. The fin assembly is constructed so that the coolant channels are narrowed as a function of the temperature of the liquid coolant. The narrowing channels increase the coolant velocity and thereby improves the heat transfer at what would otherwise become the hot end of the module. The coolant velocity is increased at the appropriate rate to maintain equal cooling along the direction of coolant flow.

Abstract: 1. A generator for producing random binary bits comprising in combination, eans for producing a random noise electrical signal, means coupled to the output of said signal producing means for converting said random noise electrical signal into a variable width square wave signal having polarities proportional to the polarities thereof at any given instant, means connected to the output of said converting means for producing a plurality of constant frequency pulses the number of which is proportional to the widths of those portions of the aforesaid variable width square wave signal having the same polarity, and means effectively connected to said pulse producing means for timely sampling said pulses in terms of binary bits.
