Abstract: A vacuum dehydrator for processing an oil containing entrained contaminants such as water, air, and particulates comprises a tower enclosing upper and lower chambers. A random packing is contained in the upper chamber. The oil is preheated to a temperature above the boiling point of water and is introduced into the upper chamber for downward flow through the random packing into the lower chamber. Entrained air and water is retained as water vapor in the upper chamber, and particulates are retained in the random packing. Heated ambient air is introduced into the lower chamber for upward flow through the random packing into the upper chamber, and the upper chamber is cooled to condense the water vapor. Oil and condensed water are pumped respectively from the lower and upper chambers.

Abstract: A process for manufacturing coffee extract is disclosed wherein an eductor is used to keep standing bodies of extract under sufficient agitation to prevent the coalescing and settling-out of insoluble materials contained in the extract.

Abstract: A downdraft type carburetor having a conventional idle speed air/fuel mixture channel has an air/fuel mixing chamber that mixes the idle channel air/fuel mixture with idle bypass air from the main induction passage, the mixing chamber being connected to discharge into the induction passage below the throttle valve through a nozzle containing an orifice sized with respect to a larger orifice in the air bypass passage to provide a pressure differential creating sonic flow, the nozzle extending so that the sonic flow is followed by a shock wave, the turbulence created atomizing the fuel.
