  • Patent number: 6722871
    Abstract: The present invention includes a device for dispensing food products such as ice cream, yogurt, sherbet, sorbet, whipped topping, cheesecake filling, pudding and the like comprising a scoop having a channel portion with a tapered, semi-circular cross section along a curved axis. The scoop is designed to be mounted on or adjacent to a container of food product and to extend substantially across one half of the opening of the container. The scoop may be mounted to the container with the smaller cross-sectional area mounted adjacent to the sidewall of the container and with the larger cross-sectional area mounted proximate the center of the container. Alternatively, the scoop may be mounted with the larger cross-sectional area adjacent the sidewall and with the smaller cross-sectional area mounted proximate the center of the container. The cross-sectional area of the channel portion in either case is tapered from end to end.

  • Patent number: 6623567
    Abstract: A method for high concentration carburizing and quenching of steel is provided which is carried out by a treatment process including the steps of carbonitriding the steel at temperatures of from about 800 to about 880° C., and subsequently quenching the steel at a temperature higher than the carbonitriding temperature. In the carbonitriding step, the steel is treated with carbon concentrations in a carburizing atmosphere taken as about 0.7 to about 1.2% and with 3 to 8% of ammonia gas (NH3) being added, for example. This dissolves network-like carbide in austenite and, when the austenite is transformed into martensite by quenching, distributes the dissolved carbide in the form of granules approximately uniformly in the martensite.

  • Patent number: 6527854
    Abstract: A low free energy method for more rapidly diffusing an impurity as exemplified by boron, into a natural or synthetic diamond or other crystalline element in powdered or granular form, without degradation of the crystalline structure. The present method includes the steps of providing a mixture of the diamond or other crystalline element and the impurity in a solid phase; treating the mixture to bring the impurity into conforming contact with the outer surface of the crystalline element; and heating the mixture to a temperature between about 200° C. and about 2000° C. As an example, a diamond is disclosed having boron as an impurity diffused into the crystalline structure thereof by the present method, at a ratio of from about 0.1 part of the impurity per 1 million parts of the diamond to about 600 parts of the impurity per 1 million parts of the diamond.
