Abstract: A method of making reduced oil content food chip products, such as potato chips and corn chips, includes circulating liquid carbon dioxide, over the food chip products to extract oil. Reduction of oil content to less than 50% of its initial value, including reductions to 25%, may be achieved while retaining flavor and texture comparable to conventional deep fried chips having an oil content of 30% to 40%. The oil which is recovered from the liquid carbon dioxide used for extraction has an appearance and quality which are substantially the same as virgin frying oil and may be reused to deep fry chips.

Abstract: An improved Francis-type turbine runner permitting a significant reduction in cavitation is provided by shaping the runners extending between the ring and crown in such a fashion that at least a portion of the area of the streamlined suction face side of each blade is (when used as a turbine) exposed when viewed in the axial direction looking away from the crown.

Abstract: A process which improves the handleability of resilient, acrylic graft rubber particles which comprises coagulating the rubber particles, then contacting the coagulated particles in the coagulation medium with a dispersion of a non-resilient alkyl methacrylate resin and coagulating the alkyl methacrylate resin on the surface of the rubber particles. The particles of alkyl methacrylate resin adhere to the rubber particles and prevent the normally sticky rubber particles from adhering to one another.

Abstract: Apparatus for filtering particulate matter in a fluid (e.g., gas) and in particular small particulate matter, the apparatus including a rotating filter, an expander or turbine for extracting energy from the fluid after the fluid has passed through the filter, an aerodynamic seal comprising a rotating multiple fin or vane member which rotates with the filter and expander, and depending upon the type of particulate matter, there is provided a spray system or a scrubbing system to aid in filtering the particulate matter.
