  • Patent number: 5547112
    Abstract: A drip-less vessel has a flange at its upper end which is angled at about with respect to the horizontal, a ramp of approximately 3/8" located behind the junction of the inner surface and the edge of the vessel, and a smooth internal contour with direction changing surfaces blended into one another so as to avoid sharp or noticeable protrusions which could be sensed by the sensitive tissues of the mouth of a user.

  • Patent number: 5537917
    Abstract: An improved, multi-purpose cake pan which offers the flexibility of having both a flat-cake pan and a tube-cake pan, the compact storageability of a single cake pan, and a simplified means of removing either a flat-cake or a tube-cake from the outer rim of the cake pan itself. Two separate cake pan insets are provided to allow the cake pan user to bake either a flat-cake or a tube-cake. Both such insets fit securely into an outer rim--giving the appearance of a standard, one-piece cake pan. A tube-cake handle quickly connects to the tube-cake inset and allows it to be easily removed from the outer rim of the cake pan. A quick procedure for removing the flat-cake inset is performed by simply lowering the cake pan over the tube-cake inset whereby a vertical column of the tube-cake inset pushes the flat-cake inset up and out of the outer rim of the cake pan.

  • Patent number: 5323693
    Abstract: An improved cooking device is provided for fat-free or low-fat frying of foods. A combination frying pan and removable insert allows the drainage of excess fat without interruption of the cooking operation. Fat is collected on the convex cooking surface of the insert and drains radially outward toward apertures disposed above a grease reservoir located in the outer bottom periphery of the frying pan. The insert overlies the reservoir and may be easily removed and replaced during the cooking operation. The pan fits over standard size electric burners.

  • Patent number: 4951018
    Abstract: An electromagnetic contactor includes a housing assembly that may be adapted for one, two, three or four poles. An armature is affixed to a contact carrier either by a flat leaf spring that passes through a slot in a laminated armature or by a press fit of a solid armature into the contact carrier. In one embodiment of the invention, a housing assembly snaps into a base to permit a maximum amount of automatic asssembly and a minimum number of components. These components include a base, a magnet assembly having at least one shading coil, a formed coil assembly, two symmetrically disposed springs to return a contact carrier to a neutral position when the coil is de-energized, an armature to complete the magnetic circuit that is attached to the contact carrier, a contact block that supports terminals and stationary contacts, and a contact carrier that carries one or more moving contacts into engagement with the fixed contacts.
