Title: Cooking stove
Inventor: JOHNSTON HAROLD E
IPC: F24C5/20
Filed: 1977-09-26
Granted: 1980-03-18
Abstract: TITLE          COOKING STOVE          ABSTRACT OF THE DISCLOSURE           A compact cooking stove including a combustion area partially surrounded by a wind screen having a side opening which faces the wind to direct air to the burning fuel.  An exhaust opening is formed adjacent a cooking pan placed at the top of the wind screen so that hot exhaust gases from the burning fuel pass upwardly toward the pan.  In a first embodiment heat is supplied by a generally cylindrical burner plate including a recessed, central portion forming an alcohol fuel dish surrounded by a fairly broad rim.  A plurality of pot-supporting tabs project upwardly from circumferentially spaced points about the rim to support a cooking pan above the fuel dish and rim.  Heat from the burning fuel imparted to the bottom of the pan is radiated to the rim of the burner plate to heat the fuel in the fuel dish in order to promote vaporization of the fuel which increases the heat gener-ated by the stove.  A relatively thick heat-retaining disc may be formed in the fuel dish to retain and stabilize heat collected by the rim.  The wind screen is placed around the burner plate and the lower portion of the cooking pan.  In a second embodiment of the cooking stove the wind screen is placed on the top surface of a metal fuel container with the wind screen partially surrounding an opening in the top of the container,  A cooking pan is supported on several legs projecting upwardly from the top edge of the wind screen to form exhaust openings beneath the pan.  When the stove of either embodiment is being transported, the rim of the cooking pan locks together with the rim of a cup to form a waterproof enclosure in which the stove components are stored.  The stove is carried by inserting the belt of an individual through a pair of loops formed along the bottom of the cup.

Abstract: ABSTRACT OF THE DISCLOSURE   Method and apparatus are provided for producing a filament from molten rapidly crystallizing filament-forming thermoplastic polymers.  The apparatus includes a chamber for the molten crystallizable polymer.  Heat-ing means are associated with the chamber for melting the polymer and for maintaining the polymer in a molten condition.  An electrically conductive material is disposed at one end of the chamber, the electrically conductive member including an orifice formed therethrough.  Controllable means are provided for applying a preselected controlled pressure to the molten poly-mer, the controlled pressure being sufficient to form a static flat meniscus of the molten polymer at the orifice, but being insufficient to extrude the molten polymer through the orifice.  An apertured plate, which is formed of electrically conductive material, is disposed at a predeter-mined distance from the orifice, the aperture in the plate and the orifice being aligned.  Finally, means are provided which electrically connect one pole of a D.C. power supply to the electrically conductive material through which the orifice is formed, and which connect the other pole of the D.C. power supply to the apertured plate.  In this way, an electronic static field is created between the orifice and the apertured plate.  The value of the applied voltage is large enough to overcome the static flat meniscus at the orifice and to form a cone terminating in a molten polymer jet, but is insufficient to generate an electrical discharge between the orifice and the apertured plate.  Above that certain critical field strength, the flat meniscus at the orifice is deformed into a conical shape from which a fine continuous jet of molten polymer is drawn.  Subsequent crystallization of this jet yields a continuous filament which can be drawn or otherwise treated in separate finishing operations so as to optimize its properties.          Thus, the high pressure extrusion used in the past to form filaments is obviated.
