Patent CA-2398823-A1 (CA)
Inventor: ILIFF EDWIN C
IPC: G16H10/60
Filed: 2001-02-14
Abstract: Structure-based processing includes a method of diagnosing diseases that wor ks by arranging diseases, symptoms, and questions into a set of related disease , symptom, and question structures, such as objects or lists, in such a way th at the structures can be processed to generate a dialogue with a patient. A structure-based processing system organizes medical knowledge into formal structures and then executes those structures on a structure engine to automatically select the next question. Patient responses to the questions lead to more questions and ultimately to a diagnosis. An object-oriented embodiment includes software objects utilized as active, intelligent agents where each object performs its own tasks and calls upon other objects to perform their tasks at the appropriate time to arrive at a diagnosis. Alternative symptoms, synergies, encoding of patient responses, multiple diagnostic modes, disease profiles or timelines, and the reuse of diagnostic  objects enhance the processing of the system and method.

Title: Method for operating a coke oven battery
Inventor: SCHUMACHER RALF
IPC: C10B27/06
Filed: 2002-03-23
Abstract: The object of the invention is a method for operating a coke oven battery comprised of a large number of identical coking chambers, a raw gas receiver, and throttle devices arranged in the raw gas receiver for individually controlling the gas pressure in the coking chambers. The throttle devices each comprise an immersion bucket that is acted upon by water. The coking chambers are connected with the raw gas receiver by gas lines terminating in immersion pipes in the immersion buckets of the throttle devices.  According to the invention, throttle devices are employed that comprise an overflow that can be vertically adjusted by an actuating drive for controlling the level of the liquid in the immersion bucket. For a coking chamber to which a pressure control device is allotted, the setting signals for the actuating drive allocated to the time pressure curve in the process of carbonizing coal to coke are recorded in the form of a position-time curve. The actuating drives of throttle devices that are allocated to coking chambers without pressure control devices are controlled according to the position-time curve.

Title: A systematic approach to mechanism-of-response analyses
Inventor: MONFORTE JOSEPH A
IPC: C12Q1/6883
Filed: 2001-07-20
Abstract: The present invention provides methods for identifying new compositions having one or more desired activities, and methods for identifying organisms that are sensitive or resistant to a drug composition. The methods are based upon genetic response profiles generated for an initial set of compositions, where at least one member of the set of compositions has been shown to have at least a first demonstrated activity and a second desired activity. By examining the patterns of genetic and cellular responses (i.e., the genetic response profiles) evoked by a first set of "known" compositions having varying degrees of one or both activities, a preferred pattern of genetic responses can be formulated which corresponds to the desired activity, but not to the demonstrated activity. Additional sets of compounds or compositions can then be screened for the desired genetic response profile, thereby identifying new compositions having the desired activity. Furthermore, populations of organisms can be screened for sensitivity or resistance to drug compositions, based upon comparison of genetic response profiles to the preferred pattern.

Abstract: A metal wood-type golf club includes a weight member disposed along the interior surface of the bottom wall. The weight member is sized and distributed so as to increase the moment of inertia of the golf club about a vertical axis extending through the center of gravity as well as lowering the center of gravity of the club head itself. The longitudinal position of the weight member is selected as a function of the loft angle of the club face. The weight member is moved forward for a club having a small loft angle and moved rearward for a club having.a high loft angle so that the vertical gear effect about the center of gravity partially offsets the natural backspin of the club to a greater or lesser degree depending on the loft angle of the club.
