  • Patent number: 6164707
    Abstract: A fluid-carrying swivel joint has a stepped bearing race arrangement on interconnecting hubs having an improved bore seal capability. The stepped arrangement allows more ball bearings per adjacent race which allows equal distribution of hydrostatic end loading to each bearing race, thereby enabling maximum total end loading while minimizing load concentration on a particular bearing race section due to increased total ball and race contact area. A straight bore type seal is used to reduce surface area subject to axial pressure and to minimize rotational friction.

  • Patent number: 6153860
    Abstract: A food preparation system, a controller, a computer readable memory, and a method for providing precise on-line control of a heat transfer process on a food item is disclosed. The food preparation system comprises a heating and/or cooling chamber, a sensor, and a controller. The chamber is configured to transfer heat to or from the food item during a phase of the heat transfer process. The sensor is configured to sense an actual temperature in the heating and/or cooling chamber at each real time epoch of the phase. The controller is configured to control the heating and/or cooling chamber according to a scheduled time-temperature profile over the phase. It is also configured to, at each real time epoch of the phase, simulate an internal temperature in the food item based on the sensed actual temperature at that real time epoch. It is further configured to terminate the phase when the simulated internal temperature at a particular real time epoch reaches a target internal temperature.

  • Patent number: 6146610
    Abstract: Arsenic is removed from elemental phosphorus by treating it with an oxidized form of iodine in a sufficient amount and for a sufficient time to obtain the amount of arsenic reduction desired. When iodine is the source of the oxidized iodine an oxidant is additionally used. An oxidant is optionally used when an oxidized iodine is used. The oxidant also reduces the amount of antimony present in the elemental phosphorus, and a dilute oxidant rinse removes any residual iodine source and also results in a water-white liquid phosphorus.

  • Patent number: 6142292
    Abstract: The bearing includes a cylindrical bearing, such as a sleeve bearing or a ball bearing, having a central opening for receiving a shaft and having a first radial surface. The assembly includes a bearing housing having a surrounding wall which defines an open distal end and an open base end. The housing has a second radial surface extending inwardly from the surrounding wall. The assembly includes a support wall arranged adjacent to the open base end of the housing. The assembly includes a plurality of threaded fasteners which are inserted through holes provided on the bearing housing and are threaded onto threaded apertures provided in or behind the support wall. Tightening of the fasteners draws the bearing housing to the support wall. A spring, such as a Belleville washer, is placed between the support wall and the bearing to resiliently press the first radial surface against the second radial surface. When the housing and support wall are drawn tight the spring is compressed under great force.
