Patent CA-2122393-A1 (CA)
Inventor: BURBANK JOHN E III
IPC: A61B17/128
Filed: 1994-04-28
Abstract: There is described herein a ligating clip applier which contains: a handle assembly; a jaw assembly connected to the handle assembly and containing a shaft and a pair of jaws. The shaft defines a longitudinal axis which lies in a central horizontal plane. A magazine of clips is stored on one side of the plane. The jaws are positioned so that they are on the opposite side of the plane. This configuration allows the clip to be loaded into the jaws across the plane, resulting in greater visibility of the clips as they are loaded into the jaws.      Further, there is provided a jaw closure mechanism operable in connection with the jaws of this device so that the jaws contact the legs of a ligating clip first distally and then proximally. Thereafter the jaws are parallel at least once during closure, and the closure of the clip legs is, indeed, distal and then proximal. This improved procedure insures that in virtually all instances, the angle included between the clip legs at the crown is o o. Motion of the clip feeding and jaw closing mechanisms are accomplished without lost motion, via a pair of interengaged mechanisms connected by a single tension spring to one another, and operating separately from the body of the device. This configuration results in a more efficient, easier to operate more reliable clip applying device.

Title: Method and Apparatus for Drying the Fuel of a Fluidized-Bed Boiler
Inventor: RAIKO MARKKU
IPC: F23K1/00
Filed: 1992-11-18
Abstract: The present publication discloses a method and an apparatus for drying the fuel used for firing a fluidized-bed boiler (1). The hot, inert solids of the fluidized bed are circulated by a regulated rate from the furnace (2) to a simple dryer (11) incorporated into the fuel feed line (7) to the boiler (1), whereby the fuel is dried and steam is generated. By virtue of controlled bed solids recirculation, a constant temperature of the dryer (11) can be maintained, thus permitting the omission of all heat transfer surfaces from the dryer (11). The nearly clean steam released from the drying process is routed from the dryer (11) to useful applications.

Title: Methods and apparatus for optimizing decision making
Inventor: KOWALSKI THADDEUS J
IPC: G06N5/00
Filed: 1994-05-27
Abstract: Methods and Apparatus for Optimizing Decision Making Abstract Techniques for optimizing decision making apparatus by instrumenting the apparatus and running it on test data which has the characteristics of the data upon which the decision making apparatus is to be used. The information providedby the instruments is then used to reorder the application of the criteria used by the decision making apparatus to the data. As disclosed, the decision making apparatus is a rule-based system which employs a decision network to evaluate the rules. The decision network includes within tests, between tests, and result caches which hold the data items which pass the tests. The optimization is done by rearranging thecondition elements of the rules so that the flow of data through the decision network is minimized. The decision net is instrumented with two counters for each test and a counter for each result cache. The counters for a test indicate how many times the test was performed on the test data and how many times the test failed; the counter for a result cache is incremented each time an item of data is added to the cache and decremented each time an item is removed. A function employing the counter values is used to make a list of condition elements by decreasing restrictiveness. The list and a graph of the condition elements which relates the condition elements according to shared variables are then used to reorder the rules, whereupon the decision network is reconstructed as required for the reordered rules.

Abstract: A circumferential flow path (86) is established about an axis of rotation, while the circumferential flow path (86) is rotated about the axis. Blood is introduced into the rotating circumferential flow path (86) through an inlet port (122) having an axis that is parallel to the axis of rotation. The axial inlet flow together with the circumferential separation flow creates a vortex region (148) that circulates about the port axis and stretches across the circumferential flow path (86). The vortex region (148) perfuses the blood uniformly into the circumferential flow path (86) for separation into constituent parts.

IPC: A01D43/00
Filed: 1994-09-02
Abstract: ABSTRACT            With a limited separating spacing immediately upstream of a mowing implement      rotating in a horizontal plane, a lawnmower has an upward extraction implement      rotating in the same direc-tion as the advance direction       about a horizontal transverse axis       and which is located in a common casing,       but in a separate casing chamber.        The upward extraction implement is disengageably driven by means of a gear by the drive motor       of the mowing implement      and is essentially located between the front wheels,      which are vertically adjustable for the joint setting of the working height of the two implements.      Thus, it is possible to in each case separately and also join-tly and simultaneously work with the two implements,         so that numerous use possibilities exist.
