Abstract: A connector includes a plug and a socket that are connected and integrated to each other. The plug and socket each have an end to which a connection line may be respectively connected. The plug of the connector includes a plug body for connecting to the connection line and having a fitting recess on one end, a plug holder configured to be freely rotatably fitted over the plug body without slipping, and a stopper fitting configured to be freely rotatably fitted over the plug body and slidable in the shaft center direction. The socket of the connector includes a socket body for connecting to the connection line at one end and a socket holder. The socket body has an insertion portion configured so as to fit into the fitting recess of the plug body. The socket holder is configured to be freely rotatably fitted over the socket body without slipping.

Abstract: A connector includes a plug and a socket that are connected and integrated to each other at one end. The plug and socket each have another end to which a connection line may be respectively connected, whereby the connection lines connected respectively to the plug and socket are connected to each other. The plug of the connector includes a plug body for connecting to the connection line on one end thereof and having a fitting recess on the other end thereof, a plug holder shaped in a substantially cylindrical form and configured to be freely rotatably fitted over the plug body without slipping off an outer peripheral surface of the plug body, and a stopper fitting biased outward along a shaft center direction and configured to be freely rotatably fitted over the plug body and separately slidable in the shaft center direction. The socket of the connector includes a socket body for connecting to the connection line at one end thereof and a socket holder shaped in a substantially cylindrical form.

Abstract: An apparatus is disclosed for composting a relatively large quantity of organic materials with a relatively small agitator adapted to travel in a zig-zag path in a generally rectangular heaping zone where the organic materials are piled in a layer.

Abstract: A composting method uses an "H"-shaped apparatus comprising four rotatable paddles disposed at each terminal end of the "H"-shaped arrangement, the apparatus as a whole being reversibly movable in the direction of the horizontal bar of the "H" shape. A plurality of composting sections are arranged in a row along and at opposite sides of the horizontal bar. The composting operation is performed for the plurality of sections according to a predetermined schedule so that, when the apparatus is under operation, four sections are simultaneously under operation, one of the four sections may be receiving material and three sections are simultaneously under agitation by the paddles and at the other section or sections the material may be taken away.

Abstract: A method and apparatus for use in pulverization and/or segregation which is suitable for obtaining the desired quality of the pulverized materials. Such pulverization is performed by restricting the discharge rate of the mixture through the discharge opening and thereby controlling the quantity and time the mixture remains within the pulverizer. The pulverizer is provided with a weir at the discharge end of the drum or cylinder for such restricting purpose. Also, beaters disposed within the pulverizer are provided with safety means enabling the beaters to pivot when a relatively stiff constituent is encountered in the mixture.

Abstract: An apparatus and a method for processing municipal waste with increased processing capacity are provided. The apparatus includes at least a cylindrical screen having ridge projections on the inner surface thereof and a group of beaters mounted on a central shaft extending axially through the cylindrical screen. In carrying out the method, the municipal waste charged into the cylinder receives powerful beating and shearing due to the interaction caused by the relative rotation between the tips of the beaters and the ridge projections thereby remarkably increasing the processing capacity.
