  • Patent number: 9140448
    Abstract: A vibratory feed mechanism for pellet fuel combustion device provides a spring-mounted feed plate communicating with a fuel reservoir and vibrated by an electric motor carrying an offset counterweight to move pelletized fuel from a first position on the feed plate to a feed orifice defined in the feed plate for communication of the pelletized fuel to a metering channel and a drop tube for conveyance to a fire pot. A control board communicating with an igniter, at least one thermocouple, a combustion fan, and the electric motor allow a user to set a desired parameter which controls the rate of pelletized fuel feed and temperature and operating conditions.

  • Patent number: 7153531
    Abstract: Food components including a triacylglycerol component and a bulking agent are provided. The triacylglycerol component typically has a melting point of about 100 to 120° F. and constitutes about 20 to 35 wt. % of the food components. The food component can be formed by heating a composition which includes the triacylglycerol component and bulking agent under conditions sufficient to form an outer layer having certain desired physical characteristics. Food products incorporating the food components are also provided.

  • Patent number: 6605309
    Abstract: Food compositions including a triacylglycerol component and a bulking agent are provided. The triacylglycerol component typically forms about 20 to 35 wt. % of the food composition. The triacylglycerol component can be formed by combining a lauric triacylglycerol with a saturated 16/18 triacylglycerol. The triacylglycerol component can be characterized by its fatty acid composition, which typically includes at least about 30 wt. % lauric acid and at least about 10 wt. % total of palmitic acid and stearic acid. Methods for making the food compositions and food products incorporating the food compositions are also provided.

  • Publication number: 20030026890
    Abstract: Nut-like food compositions including a triacylglycerol component and a bulking agent are provided. The triacylglycerol component typically forms about 20 to 35 wt. % of the nut-like food composition. The triacylglycerol component can be formed by combining a lauric triacylglycerol with a saturated 16/18 triacylglycerol. The triacylglycerol component can be characterized by its fatty acid composition, which typically includes at least about 30 wt. % lauric acid and at least about 10 wt. % total of palmitic acid and stearic acid. Methods for making the nut-like food compositions and food products incorporating the nut-like food compositions are also provided.

  • Patent number: 4852466
    Abstract: Floating the diaphragm portion of a diaphragm sensor in the pressurizing fluid frees the diaphragm from exterior housing forces, and makes overall manufacture and replacement inexpensive. A diaphragm can be protected from exterior stress by interspersing a channel between the diaphragm edge and the closure and support structure of an enclosing housing. By extending the channel and incorporating an adequate seal, the diaphragm structure may be made replaceable. The replaceable diaphragm further allows use of a smaller amount of costly materials, and makes repair less costly.
