  • Patent number: 6589205
    Abstract: A medication infusion system includes an implantable device and an external control device. The implantable device includes a constant flow pump and a flow rate that may be altered by commands received from the external control device. Power to execute the commands is also provided to the passive pump from the external control device. The external control device sends a command only when a flow rate change is to be made, or when status information is required. In one embodiment, the flow rate provided by the passive pump is controlled by a flow regulator, where the flow rate is changed by changing the restriction of a passage between regulator chambers.

  • Patent number: 6588350
    Abstract: An automatic coal stoker is provided with internal means to increase the sensible heal outflow from the operating stoker, which means comprises a modified stoker housing that provides a first combustion chamber and an abutting second chamber for induced air heat exchange with the hot combustion gases. A tubular means is disposed in the second chamber which intakes the combustion gases to be vented and extracts much of their sensible heat, and then directs by forced convection, the heated air useful to the stoker environment, while venting the spent combustion gases to the standard flue means.

  • Patent number: 6589208
    Abstract: A self-deploying catheter assembly comprises an anchoring device mounted to a tube. A distal end of the anchoring device is held in a fixed position by a releasable suture while a proximal end is freely movable between a proximal position and a distal position defined by a stop on the tube. During insertion into a body cavity, the anchor automatically maintains a low-profile state with the ends spaced apart. Once fully inserted, the anchor self converts into a high-profile state when the tube is slightly withdrawn, bringing the ends closer together. The suture is disengaged to release the distal end of the anchor in order to facilitate a low-profile state for withdrawal of the assembly.

  • Patent number: 6584703
    Abstract: The invention relates to a method by means of which the machine-direction moisture of a web being calendered or coated and calendered can be controlled in an optimal manner that takes into account moisture content changes along the entire path of the coating and drying process. Advantageously, all the dryers and the calender of the coater section are controlled in an integrated manner in order to obtain a controlledly processed product which is optimized in regard to energy consumption and product quality. Each process section and unit contributing to the drying of the web is identified by means of a mathematical submodel describing the specific evaporation rate in the respective process section/unit and, by chaining these submodels, a composite model is compiled for the entire process, whereby the composite model makes it possible to manage the drying operation in the process so that the individual units are controlled as a portion of the overall process.

  • Patent number: 6581302
    Abstract: In known rack dryers, the drying effect is weaker in the outer area on the side of the air intake into the pipe chambers than in the other areas. Said weaker drying effect is caused by turbulence in this area, which leads to a drop in the static pressure. The aim of the invention is to provide a dryer which ensures even drying of the goods across the entire width, even in the problem areas. The rack dryer is equipped with conductive bodies (20, 26) which are located on the partition wall (5) and which streamline the current in the area of the air intake into the pipe chambers in such a way, that a predominantly even static pressure prevails throughout the entire pipe chamber. The invention can be used for drying sandwich-type plaster board or wood veneer.

  • Patent number: 6581298
    Abstract: A nozzle for a fabric dryer whose cross sectional area tapers from the proximal end thereof to the distal end thereof. The nozzle has a fabric side that is juxtaposed relative to the fabric. The fabric side of the nozzle is provided with a slot that extends therealong. The slot has flanges that penetrate away from the fabric side of the nozzle and open inwardly into the nozzle. A plurality of baffles are positioned between the flanges, along the slot. Each of the plurality of baffles is directed toward the fabric side of the nozzle and is inclined toward the proximal end of the nozzle to deflect hot air from the slot, so that the hot air projects normally onto the fabric so as to avoid moving the fabric off the fabric conveyor of the fabric dryer.

  • Patent number: 6581300
    Abstract: A method and apparatus for drying veneer wherein the feeder upstream of the drying station displaces the veneer at different speeds on the right and left sides of the transport path of the veneer as seen in the direction of transport so as automatically to impart an inclined orientation of the veneer of 20° to 60° to a line perpendicular to the transport direction before the veneer reaches the drying station. In the drying station and the cooling station the veneer retains this inclined orientation and in these stations the veneer is subjected to multiple rerouting or the application of pressure.

  • Patent number: 6579255
    Abstract: A method and apparatus provided for controlling fluid control to and from an eye or a phacoemulsification handpiece. The handpiece includes an ultrasonically driven, hollow, sleeved needle and the method includes inserting the needle and sleeve into an eye for phacoemulsification of eye tissue and introducing fluid into the eye through an annulus established between the sleeve and the needle. Aspiration of fragmented tissue and fluid from the eye is conducted through the hollow needle. An initial irrigation fluid pressure is determined and the irrigation fluid flow and aspiration fluid flow are adjusted based upon the initial determination. Thereafter continued determination of irrigation fluid pressure is utilized to continuously adjust irrigation fluid flow and/or aspiration fluid flow.
