  • Patent number: 8621987
    Abstract: A cooking skillet that provides a unique automatic stirring system for continuously stirring foods during cooking. The cooking skillet comprises a base, a receptacle, a heating element, and an automatic stirring system. The automatic stirring system comprises a stirring wand located in the receptacle and a bracket located in the base. The stirring wand and the bracket are attracted to each other through magnetic forces that provide sufficient magnetism to attract one to the other. A motor is attached to the bracket by a connecting rod and provides the means to rotate the bracket in a clockwise direction. The magnetism between the magnets in the bracket and the magnets in the stirring wand forces the stirring wand to rotate in connection with the bracket. During rotation, the stirring wand is designed to mix the food contained within the receptacle.

  • Patent number: 6161363
    Abstract: Disclosed is the utilization of two halves for a door with tops, bottoms, and sides defining circumambient outside portions and a window portion having tops, bottoms, and sides forming a window circumambient portion, in which the circumambient portion of the outside and the circumambient portion of the window opening constitute dams which will preclude the flow of a foaming material. When the two door halves are secured together, the interior voids are filled with an expanding foam such as a two part urethane. The foam can be inserted through ports in the bottom and/or the top. In the final form, the frame two halves are secured together adhesively by the foam which adheres to the entire inner skin of both halves. The foam also provides insulation. Additionally, the foam reinforced by the skins imparts substantial structural strength to the door.

  • Patent number: 5901768
    Abstract: Disclosed is a primary door with window lights in the extreme upper portion. Optionally, the door can use a lowering window or a lowering screen self stored interiorly in a frame defined by the window track and the screen track and a lower stop in the upper half of the door. Thus the door can have a window, or a screen, or indeed can be left wide open for ventilation without diminishing the privacy afforded by the door since entire screen/window assembly is a plane well within the upper half of the door. In addition, replaceable decorative covers, such as muttons, are optionally on the outside and the inside of the door over the window area. The method relates to forming a door frame with a window opening defined by a frame and a cavity in the upper half of the door which contain the elements of vertical tracks for engaging the window and screen in a perpendicular horizontal stop for defining a frame for the window/screen assembly well within the upper half of the door.

  • Patent number: 5894706
    Abstract: A recites full view door in which the frame portion is totally molded. It may be molded in a number of processes from polypropylene or other materials, with or without additives, and other plastics suitable for large molded frames. There is an outside section of the frame and an inside section which are modified for securement each to the other. Provision is made in the interior edges of the frame for receiving the pane of glass, and then a holding assembly is provided, primarily four pieces being top, bottom and the two sides which snap-fits into the inside portion of the frame and secures the window in removable engagement to the door. In the method, means are provided on the outer half and the inner half for snap-fittingly or press-fittingly engaging each other. In addition, sonic welding, gluing, and other means for securing the outer half and the inner half of the door are contemplated.

  • Patent number: 5829508
    Abstract: Disclosed is a top mounted interior door closer utilizing as a drive mechanism a yieldable actuator which is exercised during the opening and retraction which is desirably mounted in an encasement having a closing rod extending from one end. The closing rod is secured to a pair of flanking members along a vertical axis, which members, in turn, are positioned for movement in a track. The closer is sandwiched in place interiorly by having elongate slot at the top of the door means of a cover plate. The elongate slot passes a closing link pin pivotally secured to the shaft or bushing joining the rollers or blocks.

  • Patent number: 5816806
    Abstract: A dental instrument with a large injection molded plastic handle has an elongated generally cylindrical symmetrical shape with first and second spaced apart ends. Anti-slip peripheral groves or slots are molded into the handle adjacent the first and second ends. Subsequent to the molding process, knurls are applied adjacent the first and second ends to improve the anti-slip characteristics of the handle. At least some of the knurling is positioned between the peripherally located grooves or slots. Stainless steel cones are affixed to the respective ends of the handle, either by ultrasonic welding or by positioning the cones in the molds, as inserts, and directly molding the plastic around retaining ends of the cones. Tips or points are press-fit and/or adhesively bonded into channels in the cones of the instrument. A single ended instrument carries a smooth, closed, cap at one of the ends.

  • Patent number: 5749122
    Abstract: A hidden door closer is based upon the positioning of a torsional spring adjacent the hinge edge of a door, which door has a hollow interior hidden closer portion with a closer mounted in an access opening so that the torsional spring and its housed assembly can be mounted in the opening is disclosed. The closer is mounted on the hinge side of the door. The torsional spring has a mid-portion crank which extends through an access opening with a coupler to the jamb or door frame. A pneumatic dampener is mounted in opposed relation to the torsion spring crank to slow the closing action induced by the Coil spring. Adjustment elements are provided in the dampener to emperically adjust its action prior to and after installation.
