  • Patent number: 4387485
    Abstract: The essence of the method of extracting or recovering meat of small crustaceans, e.g. antarctic krill, resides in that crustaceans are introduced into an air flow relative to the surface of the crustaceans at a given velocity required for creating a pressure drop across the internal space or cavity of the crustaceans and the air flow. Consequently, the inter-cavity pressure breaks up the shell and destroys the links between the muscular tissue and other components. When the crustaceans proceed along a helical path, the muscular tissue can be completely separated at the final stage of the treatment. The treatment of crustaceans is performed in stages, the air flow velocity relative to the surface of the crustaceans at the first treatment stage being about 500 m/s, at the second stage--from 200 to 300 m/s, and at the third stage--from 100 to 200 m/s.

  • Patent number: 4305455
    Abstract: In an air heater, an initial group of passes on the airside is arranged in the form of a package wherein the passes consisting of banks of tubes are connected in parallel with the uptake gases.The passes of the package are located predominantly at the same horizontal level, are made of tubes of the same length and run in a zone of the same gas temperatures which is dangerous insofar as corrosion can be provoked therein.The width of the packaged passes progressively increases directly with the increase in the rates of air flow through the passes, and a feeding air duct admitting the last inflow of cold air is connected downstream of the last and widest pass to the connecting air duct serving the rest of the passes of the air heater.In an apparatus like this one, assembled from standard components, minimum overall dimensions and low weight are combined with high thermal efficiency.

    Abstract: A percussive tool has a working tool mounted for reciprocations in a barrel. A collar is arranged between a shank and a working portion of the working tool. The shank of the working tool reciprocates in a guide bushing secured in the barrel to ensure reciprocations of the working tool. There is provide4d a member for determining the angular position of the working tool during the reciprications, the member comprising either the barrel proper in case of concrete breakers, or a hood, e.g. in chipping hammers. For positively controlling the angular position of the working tool, there is provided a spring having two portions of different cross-sectional configuration, a first portion being coupled for a combined rotation to the member determining the angular position of trhe working tool, and a second portion being of a cross-sectional configuration corresponding to the cross-sectional configuration of the working portion of the working tool.

  • Patent number: 4297665
    Abstract: The doughnut-type transformer comprises a spirally wound core consisting of several individual annular cores each tightened by rod members. The annular core is surrounded by transformer sections comprising the primary and the secondary windings. Each winding is composed of turns shaped as sectors in the plane of the transformer cross-section, a cooled turn of the secondary winding being placed between the turns of the primary winding in each transformer section. The turns of the windings surround the annular core so that the geometric center of each winding is displaced from the geometric center of the annular core in the cross-sectional plane thereof and the geometric center of the annular core is farther from the transformer axis.
