IPC: B22D11/16
Filed: 2001-10-31
Abstract: The invention relates to a method, which is used in the area of secondary metallurgy (4) in its entirety with a final temperature-determining process step (4.1) such as a ladle furnace, for controlling the temperature of steel  from the surface of the bath of a continuous casting ingot mold (1) up to th e furnace tap (5) of a steel producing process. According to the invention, th e temperature of the steel in the surface of the bath is controlled based on t he equation TML = TLI + X ~C (X = 5 - 15 ~C) and while respecting the same such  that a jump in temperature (9) between the surface of the bath in the ingot mold (1) and a distributor (3) is detected according to the pouring rate (6)  for a predetermined billet size. In addition, the ladle history (7) with regard to the time intervals, such as ladle full , ladle empty and ladle state, such as ladle bricking up and ladle age is detected as well as a jump  in the temperature of steel between the distributor (3) and the last ladle furnace temperature (LF-ex).

Title: Methods for remotely changing a communications password
Inventor: SIMON DANIEL R
IPC: G06F21/00
Filed: 2003-04-09
Abstract: Disclosed are methods for an authentication client, having been authenticated by an authentication server, to leverage the effects of that authentication to implement a new communications password. The authentication client gets a new password from its user. From the new password and from information provided by the authentication server, the authentication client derives a "password verifier." The password verifier is then shared with the authentication server. The new password itself is never sent to the authentication server, and it is essentially impossible to derive the new password from the password verifier. The authentication client and the authentication server, in parallel, derive a new set of authentication and encryption security keys from the new password and from the password verifier, respectively. This process may be repeated to limit the amount of data sent using any one particular set of security keys and thus to limit the effectiveness of any statistical attacker.

Patent CA-2426652-A1 (CA)
Title: Shade operator
Inventor: NIJS FREDERIK G
IPC: E06B9/56
Filed: 2003-04-24
Abstract: An operator for a window or like shade serves to turn a shade roller to a new desired position as a result of a torque applied from a manually operable source, such as a chain operated wheel. The device includes a helical spring that is seated within a fixed bushing with its outer surface in contact with an inner cylindrical surface of the bushing.      When torque is applied from the manually operable source, one overlapping end of the spring is moved away from its other end to reduce the spring diameter and hence release any frictional engagement of the spring with the bushing, thus allowing the torque to rotate the spring, which rotation is transmitted to the roller. However, when no such manually applied torque is present, the spring and the roller remain effectively locked in position. Any torque applied from the roller due to the weight of a partly lowered shade acts to tend to increase the spring diameter and thus to ensure a binding frictional engagement between the bushing and the spring.

Title: Product diverter valve and collector apparatus for air drill seeding system
Inventor: OCHITWA CORY W K
IPC: A01C15/04
Filed: 2003-06-12
Abstract: An improved collector assembly comprises a generally hollow body mounted below a product supply tank for receiving plural streams of materials metered from the tank. Individual upright passages through the body corresponding in number to the metered streams from the tank receive the gravitating product streams and direct each stream into either or both of an upper loading zone and a lower loading zone in the passage. A diverter valve associated with each upper loading zone can be set to close off the upper loading zone entirely while; opening only the lower zone or closing off the lower loading zone while opening only the upper loading zone. Thus, air streams passing transversely through the upper and lower loading zones respectively can be supplied with variable amounts of metered product, depending upon the position of the diverter valve within each passage. By providing multiple supply tanks and multiple collector assemblies, various product delivery scenarios can be achieved including single shoot, double shoot and triple shoot effects. In a preferred form of the invention all diverter valves are actuated by a common actuating mechanism for simultaneous adjustment.

Title: Low frequency vibration assisted blood perfusion system and apparatus
Inventor: HOFFMANN ANDREW KENNETH
IPC: A61B17/22
Filed: 2003-09-04
Abstract: An emergency system for the treatment of a patient (20) experiencing an acute thrombotic vascular occlusion, comprising a non-invasive, vibration device (10), in conjunction with pharmacological agents, for disrupting and lysing thrombosis, relieving spasm (if associated), and thereby restoring blood perfusion. The vibration device (10) is operable to deliver vibration within the 1-1000 Hz range, at a selectable displacement amplitude of 0.1-10 mm. For acute myocardial infarction cases, an operator places an attachment interface comprising a pair of contacts (12), to bridge the sternum of the patient at the fourth intercostal space. Vibration is initiated at 50 Hz (or any frequency, preferably within the 40 - 120 Hz range), and adjusts vibration to a maximal displacement amplitude deemed tolerable and safe to the patient (20), concurrently with the administration of thrombolytic agents, or any other form of medical therapy. A synergistic effect is achieved between vibration and medical agents to facilitate the disruption of thrombosis, and restore blood perfusion.
