Abstract: A drill bit for use in combination with a through-the-steel drill stem, the drill bit including an elongated body portion having a bore through which cuttings may be removed through the drill stem, a web for receiving a drill tip, and a sleeve attached about the body portion thereof, the web thereof having axially extending faces coutoured from the periphery of the body portion toward the axis thereof, and the sleeve extending from the body portion and in spaced apart axial relation to the contoured faces of the web in a manner to define drill cut receiving ports opening upwardly to the drill tip and downwardly to the bore of the body portion. The drill bit may be provided with a male keeper or retainer to mate with a complementary female receptor of the drill stem for interconnection of the drill bit to the drill stem.
Abstract: A pourout fitment/closure that may be applied as a single unit to a container for liquids, includes a plurality of areas providing a liquid tight seal as torqued onto a container, and wherein, on removal of the closure, the fitment regulates and provides a smooth rate of flow of liquid as it is dispensed therethrough from the container.
Abstract: Conventional automatic drip coffee makers require about one minute of manual involvement to commence a brewing cycle.The automatic drip coffee maker herein disclosed makes a full decanter of coffee within 11/2-2 minutes following the one minute manual involvement.The automatic drip coffee maker of the present invention uses preheated water but only the amount required for a decanter of coffee (1/2 gallon) making it unnecessary to employ a large reservoir. The concept, in a preferred embodiment, is to commence the brewing cycle by an almost instantaneous dump of the preheated water to a transfer tank which, in turn, meters heated water to the grounds at such a rate as to insure almost immediate contact between all the coffee grounds and all the hot water. The dump time for preheated water from the preheated reservoir to the transfer tank is less than the time required to fill a receptacle with cold water.
Abstract: The pot life of a quantity of decanter contained coffee is significantly increased by maintaining a substantial temperature differential between the surface of the contained coffee and the bottom contents thereof; and dispensing coffee from the bottom of the decanter.The reduced surface temperature, as contrasted with the higher "drinking temperature" maintained at the bottom of the decanter from which coffee is dispensed, results in a significant decrease in oxidation and a dramatic decrease in evaporation as will be apparent from the exponential nature of the vapor pressure curve for water across the temperature range in question.This pot life extension may, if desired, be further increased by maintaining superatmospheric pressure within the decanter.
