Abstract: A  rolling  fire  door  includes  a  door  hold-open/release system that includes an electromagnet which is energized by a controller when the door is in the open position.     The  energized  electromagnet  magnetically attracts a bottom bar of the rolling door to secure the door in the open position.  A key control station connected to the controller enables the electromagnet to be energized when the door is in the open position and enables the controller to deenergize the electromagnet so that the weight of the door causes the door to close.   The key control station also includes a test switch which enables the controller to deenergize the electromagnet after a delay  interval.    The  controller  also  deenergizes  the electromagnet  after  a  delay  interval  in  response  to activation of an alarm or in response to a thermal switch sensing a temperature in excess of a set point temperature.

Title: Method and apparatus for heat treating webs
Inventor: BAKALAR SHARON F
IPC: F26B13/00
Filed: 1996-06-05
Abstract: Cylinder (20) for heat-treating rotates about a horizontal axis and is heated by a complement of internal stationary infrared burners (38) that extend all along the length of the cylinder, but only partway around the cylinder, forming gap. An exhaust manifold (34) extending along this cylinder in that gap is configured to prclude local accumulation of high temperature exhaust. The accurate extent of the burner(s) is proportioned for establishing a specified cylinder heat output when the burner(s) is (are) supplied with airfuel mixture at their maximum rate. Reduction of the air-fuel supply rate over a wide range allows the cylinder heat output to be reduced as the web processing speed is reduced. When the burner is divided into segments, the temperature profile along the cylinder, i.e. across the width of the web, can be regulated to adjust the moisture profile of the web.

Patent CA-2235982-A1 (CA)
Title: A method for locating a mobile station
Inventor: SMITH ADRIAN DAVID
IPC: H04W64/00
Filed: 1998-04-27
Abstract: A method provides for the detection of the geographic location of a mobile station within a mobile network. The mobile station detects signal characteristics for signals generated by neighboring cells to create a report of signal characteristics corresponding to the location at which the mobile station resides. This report is then compared against the database of signal signatures identifying geographic locations within the cell in which the mobile station is known to be positioned. The signal signatures are then used to detect either an exact match or an approximate match to give position information of the mobile station within the cell.
Patent CA-2237250-A1 (CA)
Inventor: FOSTER RAYMOND KEITH
IPC: B65G25/00
Filed: 1998-05-08
Abstract: Alternate conveyor slats have laterally outwardly projecting, upper side portions, each with a depending, longitudinal, load transmitting bead (B). The beads (B) sit down on and slide longitudinally along bearing/seal surfaces (90a, 92a) that are a part of upper side portions of the intermediate conveyor slats (12). The alternate conveyor slats (10) are guided by longitudinal guide beams (14). Hold down members (20) secured to the guide beams (14) serve to resist unwanted upward movement of the conveyor slats (10). The intermediate conveyor slats (10) are snap-fitted onto bearings (18) which in turn are snap-fitted onto longitudinal guide and support beams (19). The weight of conveyor slats (10), and the weight of any load on the conveyor slats (10), is transmitted by the contact of the bead (B) with the bearing/seal surfaces (90, 92) to the conveyor slats (12). This weight, the weight of the conveyor slats (12), and the weight of any load on conveyor slats (12), is transmitted to the bearings (18) and from the bearings (18) to the guide and support beams (16).

Title: Recovery of nickel from copper refinery tankhouse electrolyte
Inventor: SHANE DONALD G
IPC: C22B3/44
Filed: 1998-05-14
Abstract: A method is provided for recovering nickel from a copper refinery tankhouse electrolyte as a nickel containing or nickel-copper containing cake. According to this method, a portion of the electrolyte is decopperized to a desired level of copper concentration and the so decopperized solution is subjected to an acid retardation operation, so as to separate it into a strong acid stream and a weak acid stream. The strong acid stream is then recycled to the refinery tankhouse, while the weak acid stream containing a major proportion of the nickel and of copper, if any, remaining after decopperization, is neutralized to form a precipitate which is then filtered and washed to form the final product.
Patent CA-2237826-A1 (CA)
Title: Feedback control system for telecommunications systems
Inventor: WEAVER CARL FRANCIS
IPC: H04B17/00
Filed: 1998-05-19
Abstract: Telecommunications processing is applied to a reference signal to generate a signal under test. A fidelity measure is generated characterizing the fidelity of the signal under test relative to the reference signal. A control signal is generated from the fidelity measure, where the control signal is used as a feedback signal to adjust the telecommunications processing. In one embodiment, the reference signal is a speech signal and the signal under test is a decoded speech signal generated by encoding, transmitting, and decoding the reference speech signal. The fidelity signal is an average mean opinion score (MOS) and the control signal is used to control the speech decoding processing. For example, the speech decoding processing may involve a speech decoder followed by a post filter, and the control signal is the cut-off frequency of the post filter. Such an embodiment may be applied to real-time speech processing to adjust the speech decoding processing in the receiver of a telecommunications system that includes a speech encoder in a transmitter and a communications network. Intermittently, the transmitter encodes reference signals that are also known to the receiver. The receiver performs the processing of the present invention to update its speech decoding processing to optimize speech quality.

IPC: G06F17/30
Filed: 1998-09-30
Abstract: A method for determining optimal database materializations utilizing a query optimizer in a database management system. The method takes one or more queries as inputs and using the query optimizer in the database management system generates a series of virtual materializations by materializing some subsets of the database. The virtual materializations are used to consider the relative performance benefits, i.e. cost-benefits, for the queries based on the various virtual materializations. If the query optimizer decides to use any of the materializations in its plan, then those materializations are recommended to the user, or created automatically for the user.
