Abstract: This disclosure pertains to a gas scavenger apparatus utilized to recover anesthesia-logical gases derived during surgical procedures and to dispose same to a closed vacuum line substantially limiting the inadvertant escapage into the atmosphere. A reservoir bag is connected to the patient's anesthetic circuit, which in turn is connected to a scavenger valve. The vacuum line constantly empties the reservoir bag drawing off the waste gas accumulated therein. When the reservoir bag is substantially empty, a valve admits ambient air, as well as waste gas, into a chamber emptied by the vacuum line. Thus, the vacuum line does not act on the patient's anesthetic circuit, serving only to empty the reservoir bag as waste gas accumulates therein.

Abstract: An apparatus for educational use in the playing of mathematical games utilizes forty-four playing cards. Each of the cards bears an enlarged numeral extending over the ranges from one to forty-four. Each card has the same surface carrying the enlarged numeral encoated wtih three multiplication steps and three division steps whereby one common numeral is used in each multiplication step and as a divisor in each division step. None of the numerals is extended beyond number 12 excepting the enlarged identifying numeral. The users record their proficiency in rapid use of each card, when randomly collected, on a score board having four wheels with a score imprinted thereon. The wheels are rotatably secured to a plate having windows exposing the score value on the wheels. Each of the four wheels are separately identified by a color, equivalent to the color of each four separately decorated medallions.

Abstract: A peg game apparatus utilizes a rectangular open-mouth container having a pair of semicircular notches midway of the length of the longest sides disposed in the marginal edges defining the mouth of the container. Spring loaded clips are located in the interior of the container along the elongated sides retaining therein a pair of pegs which may be secured to one another so as to provide a peg of length greater than that of the longest dimension of the container and a small and a short peg.

Abstract: A game score apparatus utilizes a display apparatus in conjunction with a miniaturized hockey game which responds to the output signal generated by placing the puck in a holding position from which it is dispensed automatically so as to simultaneously start up a display clock exhibited on a display panel in digital form. The clock continues to operate until such time that the puck is disposed in one of the two goal positions so as to descend downwardly into a transparent tube causing a photoelectric cell to sense its presence therein. Scoring automatically takes place at the same time as the clock is then stopped. Apparatus is provided for adding additional score points to either of the two displayed scores, similarly displayed in digital form. A counter is utilized to determine which game period is in progress. Such counter being operated by the timing apparatus reaching the total period equivalent to a full period play.
