    摘要： An apparatus (10) for at least partially freezing a food product which is at least partly liquid in a batch mode is disclosed including a double screw extruder (12) including first and second, substantially intermeshing, self-wiping screws (14, 16) rotatably received in a figure 8-shaped barrel (30) with minimal clearance. In the preferred form, the freezing block (20) includes multiple refrigerant channels (36) spaced closely and in the most preferred form spaced approximately 0.32 centimeters from the barrel (30) and from each other. Thus, the refrigeration system can change the barrel surface temperature rapidly and specifically in approximately one second when the food product is introduced into the barrel (30). A ratio between the radius of the flight (40) at the crest (42) to the radius at the root (38) of the screws (14, 16) is in the order of 1.04 to reduce the total amount of product in the barrel (30) at any given time and decreasing the product residence time in the extruder (12). In the most preferred form, the food product is aerated and is supplied in discrete volumes from at least one and preferably from multiple sources (48), with the supply of discrete volumes for individual servings being delayed to substantially prevent intermixing in the extruder (12).

    摘要： A surgical access apparatus includes a housing member and a portal member extending from the housing member and defining a longitudinal axis. The housing member and the portal member define a longitudinal passage therethrough dimensioned to permit passage of an elongated object. A centering mechanism is mounted relative to the housing member. The centering mechanism includes an annular element mounted for rotational movement within the housing member and about the longitudinal axis and first and second arm elements mounted to the annular element and extending radially inwardly relative to the longitudinal axis. The first and second arm elements are each positioned to intersect the longitudinal passage and are adapted to pivot relative to the housing member. The first and second arm elements are operatively connected whereby pivotal movement of the first arm element upon engagement with the elongated object causes the annular element to rotate in response thereto and effect corresponding pivotal movement of the second arm element.

    摘要： An automated beverage brewing system includes a liquid storage tank and a metering chamber. The metering chamber is at least partially submerged beneath a standing level of liquid in the storage tank. The chamber includes a sealable liquid inlet port communicating with the interior of the storage tank beneath the standing level of liquid. The chamber also includes a liquid outlet port and an aperture that receives compressed air, wherein the compressed air forces a predetermined amount of liquid from the liquid output port of the chamber for use in preparing a brewed beverage. A pump provides the compressed air and a controller monitors a pressure signal value indicative of the air pressure in the metering chamber. The controller commands the pump on to commence flow of the predetermined amount of liquid from the metering chamber. The controller then commands the pump off several seconds after detecting a drop in air pressure within the chamber, indicating that the predetermined amount of liquid has been delivered to the brewing chamber. The chamber is then vented to ambient pressure, which opens the sealable liquid inlet port and refills the chamber.
