Abstract: A limp, porous membrane of sheet (i.e., cloth) material for a fluidized outlet is disclosed. The outlet is in communication with a container, such as a hopper within a covered hopper railway car, containing a supply of particulate material for being fluidized and unloaded via the outlet. The outlet comprises an outlet housing, an outlet frame for securing the outlet housing to the hopper, an outlet opening, and outlet walls extending from the frame to the outlet opening. The membrane is secured to the outlet frame and to the outlet opening and is disposed generally on the inside faces of the outlet walls. A manifold is provided for introducing a fluidizing fluid (e.g., air) under pressure between the outlet walls and the membrane such that the fluidizing fluid flows through the membrane thereby to fluidize the lading above the membrane.

Abstract: A hair curling apparatus has a generally tubular cylindrical roller-like body with a plurality of axially extending rows, angularly spaced from each other, of relatively short generally radially extending spaced projections effective for generally frictionally engaging strands of hair as such hair is generally rolled onto and about the body; a comb member is supportingly journalled from and by one axial end of the roller-like body with such comb member being first employable for combing the strands of hair to be rollingly wound onto the roller body and being secondly employable to generally lockingly engage both such wound strands of hair and the roller body as to thereby secure the roller body in position and prevent the roller body from becoming unintentionally released from the strands of hair wound thereon.
