Abstract: The present invention provides apparatus for low-cost extraction of oil residues from oil filters. The apparatus of the invention has a mounting structure or plate to which a number of oil filters can be strapped. Over 95% of the oil in each filter can be drained therefrom under the influence of gravitational forces. Oil draining from the oil filters is allowed to gather in a pan, bucket, container or well located below the mounting plate. Connected to the mounting structure is a mechanical or electrical oscillator for imparting a vibratory oscillation to the mounting structure and, hence, to the mounted oil filters. The weak surface tension and molecular forces between the residual oil molecules and the paper filter materials will be overcome by the vibration, and the residual oil will run off.

Abstract: The invention features an apparatus and method of detoxifying and/or sterilizing waste materials utilizing ozone under pressure. The waste materials are loaded into a pressurizable chamber in which the ozone is introduced under pressure. The ozone penetrates and sterilizes and waste materials, after which the gas is evacuated from the chamber following a given treatment cycle. The evacuated gas is then fed to a second, purification chamber. Any toxic substances or contaminants that may have been released in the first waste chamber and were carried along with the evacuated gas are further purified. This is accomplished by introducing ozone into the second chamber to mix with and sterilize the evacuated waste gases. This second introduction of the ozone to purify the waste gases is an essential step of the process, and ensures that none of the toxic or contaminating substances escape to the environment.

Abstract: A closed heating system in which a silicone fluid having a high specific heat is pumped through an element formed of tetrafluoroethylene. The element is provided with a plurality of small openings through which the fluid is forced. The fluid is heated and the heated fluid is forced to blow through one or more heat transfer units through which heat is transferred to the ambient atmosphere.

Abstract: A heating system utilizing a closed oil system and a friction element for heating the oil as the oil is forced through the element. The oil's path is from a storage tank through the friction element, then to the radiation units and then is returned to the storage tank. A high temperature path and a low temperature path are provided to improve comfort control.The heating element is formed of woven stainless steel which is compressed in a mold to obtain sufficient strand density to produce a high heat of friction.
