  • Patent number: 4135489
    Abstract: A solar energy conversion system is provided which includes a black body receiver for transferring energy from focused solar radiation to a circulating gas. The receiver includes a honeycomb heat exchanger located within a chamber sealed with impingement cooled windows, the outermost one of which acts as a one way trap or diode to prevent energy radiated by the heated honeycomb from escaping to the atmosphere. The heat exchanger is formed with a number of tubes which are oriented to be illuminated "end on" for minimizing retroreflection of the incoming energy. Because of the "end on" orientation, a large majority of the incoming energy impinges on the internal walls of the tubes and is internally reflected until it is absorbed. Cool gas, which may be air, is introduced into the receiver under pressure such that the gas passes through the tubes of the heat exchanger where it is heated to temperatures that are typically in the vicinity of 1700.degree. F.

  • Patent number: 4135530
    Abstract: A rinsing tank constructed to allow low volume water flow from an ingress point at one end of the tank to an outlet. Weirs are provided in the path of water flow to normally dam scum driven by the water flow yet allow passage of water. The rinsing water is, therefore, free of scum over a major part of its surface to permit immersion into and withdrawal from clear water of parts to be rinsed. Immersion of parts raises the water level in the tanks whereby scum dammed by the weirs can rise and pass over the weirs to the tank outlet.

  • Patent number: 4135531
    Abstract: A dishwasher that has a steam boiler containing hot water and steam under pressure. The dishwasher has a dishwashing and rinsing compartment with a body of hot water, adjustable as to depth, received in the bottom of the compartment. A time controlled device delivers steam from the boiler to steam jets in the compartment for a predetermined time period for washing the dishes. The steam jets have apparatus associated therewith that will cause the steam jets to periodically entrain hot water from the body of water to deliver a pulsating steam and hot water action against the dishes for washing them. The depth of the body of water can be raised so that only live steam and water will issue from the steam jets if desired, with no pulsating action. The time controlled device delivers hot rinse water from the boiler for rinsing the dishes in the compartment after the dishwashing operation.
