Abstract: A self-deicing automotive windshield wiper system comprises a flexible wiper blade conforming to the contour of the windshield, with an expansible air-tight internal cavity extending along essentially the entire length thereof. The flexible outer walls of the wiper blade abut the internal cavity and are influenced by expansion of the cavity. An air fitting, mounted to the outside of the wiper blade communicates with the cavity. A flexible tubing connected to the fitting joins the wiper blade cavity to a pump or compressor producing a pulsating compressed air output. The pulsating air supply causes the expansible cavity to alternately expand and contract, and the pulsations are transferred to the flexible outer walls, causing them to expand and contract in unison. The flexing of the outer walls shatters any accumulations of ice clinging to the outer walls.

Abstract: An apparatus and process of treating a mixture of shellfish meat particles and shell halves is revealed and wherein the mixture is treated by elutriation in an elongated, narrow upright zone. At the upper end of the zone the meat particles are removed while at the lower end of the zone the shells are withdrawn. The shells gravitate through a region of the zone and where the water is agitated by a device for admitting air to the elutriation zone and which accelerates the shell movement toward the lower end of the treatment zone. The meat particles, on the other hand, pass through yet another region and which the passage is diminished by the admission of air so as to accelerate the upward movement of the particles toward a lateral meat discharge opening from the zone. Here the meat particles are assisted in their discharge through the opening by an appropriately positioned baffle.

Abstract: The invention concerns a method for the preparation of fish mass wherein the fish meat is separated from fat, pigment and entrail remains. The method can be utilized for fatty as well as for lean fish. This is achieved by holding fatty or lean fish raw material in an aqueous environment in which the pH is adjusted to pH 3-5, preferably pH 4, and in which the temperature is adjusted within the range of 20.degree.-50.degree. C. The fish meat with fish bones is separated from the liquid aqueous solution containing fat, entrail remains, and dissolved skin and abdominal epithelium and dark pigments from these, by methods known per se. The resulting fish mass is well suited for use as raw material in the production of manufactured foods, as the fish muscle proteins are not substantially denatured by the process.
