Abstract: A portable game apparatus is a kit which includes a lower stake member and a set of upper stake members. The members have threaded portions which allow the members to be securely joined together end to end. One of the upper members is structured to allow the upper members and lower member (when joined together) to be pounded into the ground. The upper member is detached from the lower member while the lower member remains embedded in the ground to provide a foundation for the other upper members which are specifically structured to allow various game structures such as volleyball nets, basketball nets and backboards as well as tether balls and ropes to be secured thereto. Truncated cone portions on the members (at their joined portions) add structural rigidity to the members, and ridge and groove structures secure the members in a desired joined together position.

The retaining apparatus contains an insert which is resilient and provides a cushion effect to the glass panels which may be subject to sudden impacts during shipping and handling. The insert can be removed and replaced by a thicker or thinner insert as needed.

Abstract: A method and device for diluting a first gas mixture having a known conceation of a given gas to obtain a second gas mixture containing a lower known concentration of the given gas. The device enables one to mix gases with appropriately low concentrations of a particular gas such that the gaseous mixture may be used to calibrate an instrument that measures such low concentrations of a gas.
