Abstract: A paper cutting apparatus for use in combination with a facsimile telecommunications machine to neatly and efficiently sever paper dispensed from a facsimile machine. The apparatus of the present invention is usually of a unitary construction and includes two (2) main elements: a base plate, which is generally elongated and flat, and an end plate formed integrally therewith. The end plate is bent at an angle of approximately one hundred and five (105) to one hundred and twenty (120) degrees relative to the base. The end plate incorporates a slotted opening in which the cutting edge is formed.

Abstract: A dome-shaped device usually four to five feet in diameter with a continuous channel section formed integrally around its perimeter. The device is of a unitary construction and is typically formed of a synthetic substance, such as polyethylene. The unique design of the device and particularly the density of the material comprising the device, enables it to be submersed just below the surface of the water to achieve a maximum stability. The unitary construction serves also to optimize the conduction process that is involved in the transfer of the solar energy through the walls of the device to heat the surrounding pool water. The channel section formed around the periphery of the device acts, in part, as a stabilizer to preclude against undesirable movements and sustain the degree of buoyancy necessary to maintain the unit in a submersed attitude without restricting its ability to freely bob up and down in the water.
