4680941 WASTE
economical and rapid means of on-line calibration of analytical respiratory test systems.
HEATING RECOVERY SYSTEM
Elvet M Richardson, Teik P Sim An apparatus for recovering waste heat from conventional refrigerating systems in which a heat exchanger is connected between the compressor and condenser to transfer heat to water pumped therethrough. The heated water is stored in a small holding tank and transferred to a larger water storage tank when hot water is withdrawn from the larger tank.
4680956 RESPIRATORY ANALYZER CALIBRATION APPARATUS WITH CONTROLLED RESPIRATORY GAS EXCHANGE SIMULATION Andrew R Huszczuk assigned to Research and Education Institute Inc H a r b o r - U C L A Medical Center A method and apparatus for the controlled simulation of respiratory gas exchange as it takes place in mammals, for the primary purpose of calibrating and checking the performance of laboratory and clinical test equipment systems. The method and apparatus can reproduce any range of respiratory performance by pumping and mixing atmospheric air with a gas mixture of carbon dioxide and nitrogen. The subject matter of the disclosure provides an accurate,
4681025 CHIMNEY STACK HAVING ERODABLE LINER WITH ELECTRICAL GENERATING CAPACITY John Carty An improved design associated with the fabrication and construction of a chimney stack wherein the liner material utilized as the inner liner of the stack which comes into direct contact with the flue gases being conveyed by the chimney stack to the outside atmosphere comprises erodable material having embedded therein a resistance type electrical or thermal conductivity type alarm system capable of detecting the degree of erosion of the erodable liner of the chimney stack thereby providing the ability to monitor when reconditioning of the inner liner of a chimney stack is required. Additionally, there is also incorporated the utilization of turbine blades positioned within the stream of gas flow within the chimney stack such that the flue gases cause the turbine blades to rotate, said rotation then being converted into the generation of electrical energy for utilization outside of or in accordance with the operation of the chimney stack. Furthermore, by selectively controlling the rotation of the turbine blades and their position within tile stream of gas flow within the chimney stack, there is achieved the ability to selectively generate turbulence down stream from the turbine blades£3 + 0 location thereby providing for the ability to selectively reduce the build up of corrosive particles on the erodable liner of the chimney stack thereby increasing the usable life of the inner liner. + RE
