Abstract: A dry-wall cutting tool is described. It has a block-like configuration and is designed to slide over the edge of the drywall and to cut both sides of the drywall to the same distance from the edge and at the same time as it does so. The depth of the cut (i.e. distance from the edge of the drywall being cut) can be controllably varied considerably and it will typically be between 1/8 inch and 6 inches deep from the edge of the drywall that is being cut. The cutting tool has vertical threaded shafts upon which are mounted cutting wheels and rubber or nylon rollers, with ball bearings between the shafts and the cutting wheels and rollers. Due to its construction the twin cutting can be done quickly and with little manual effort or force.

Abstract: Kites and airfoils designed in such fashion that the possibilities to observe the process by which the kite or airfoil is made airborne are maximized.Each time a gust of wind appears, the kite or airfoil rises automatically up a fixed pole which passes through it, without further direct intervention. When the airflow or wind abates, the kite or airfoil descends the pole, and rests on a restraining device located on the pole at a level higher than its lower-most level until the next gust of wind or an increase in the airflow lifts the kite or airfoil up again, and so on. The restriction of the pole also keeps the kite or airfoil within a short distance of the observer who can have a closer and better view of the process of ascension of the kite or airfoil up the pole.The applications of this invention include scientific instruments, childrens's toys and advertising devices. One embodiment of the invention is a kite which is designed to use the radio antenna of an automobile as its pole.

Abstract: This invention concerns a non-toxic method of exterminating dry wood termites, fleas, roaches, ants, weevils and the like by utilizing an inert freezing liquid such as liquid nitrogen as the killing agent. The liquid nitrogen is inserted so as to envelop the colony of objectionable organisms until the environment is reduced to a temperature of at least zero degrees Fahrenheit and maintained at that temperature for between 2 to 5 minutes. This method effectively kills the organisms by crystalizing the innards and freezing the cells, thereby eliminating the need for more dangerous and toxic poisons that are currently being used.
