Title: Method and apparatus for applying laser induced incandescence for the determination of particulate measurements
Inventor: SMALLWOOD GREGORY J
IPC: G01N15/00
Filed: 1999-05-20
Abstract: The present invention relates to a method and apparatus for applying laser induced incandescence (LII) to determine a primary particle size of submicron sized particles. The present invention has found that in addition to volume fraction information, particle size can be determined using LII due to the fact that transient cooling is dependent on the diameter of the particle. The ratio of a prompt and a second time integrated measurement from the same laser pulse has been found to be a function of the particle size. A modeling process involves a solution of the differential equations describing the heat/energy transfer of the particle and surrounding gas, including parameters to describe vaporization, heat transfer to the medium, particle heating etc. The solution gives temperature and diameter values for the particles over time. These values are then converted to radiation values using Planck's equation. Thus the technique in accordance with the invention is able to provide a more accurate particle measurement than previous LII techniques, particularly where time averaging is not possible and size measurements must be obtained from a single laser pulse. Simultaneously a particle volume fraction can be obtained in accordance with the invention. Calibration is needed to obtain a quantified volume fraction measurement. In a further embodiment of the present invention, a technique for providing absolute intensity calibration is included in the method.

Title: Diversity radio system with rds
Inventor: MCCALL DAVID
IPC: H04B7/08
Filed: 1999-06-18
Abstract: An RDS receiver having dual tuners and dual antennas operates in two distinct modes, a diversity mode and a non-diversity mode. Diversity mode is when both tuners are tuned to a signal with the same program audio content and the audio from both tuners is blended together in a manner to minimize the effects of multipath distortion. In non-diversity mode, a forcing circuit isolates the tuner output signals so that one tuner provides the audio output while the other can be retuned to any other frequency for purposes of gathering RDS data.

Title: Nonwoven metal and glass
Inventor: FOSTER RICHARD P
IPC: D04H3/12
Filed: 1998-01-27
Abstract: A glass and metal fiber material includes a web of nonwoven metal fibers and glass. The metal fibers of the web are joined by bubbles of glass to other metal fibers of the web. The nonwoven metal fibers can be the same or different lengths and do not need to be sintered. The material is flexible and capable of withstanding very high temperatures. Spaces or voids between metal fibers allow embodiments of the material to be porous. However, the voids can be completely or partially filled to alter the porosity of the material. An exemplary method of making the glass and metal fiber material in accordance with the invention includes the steps of juxtaposing metal fibers with glass fibers and heating at least the glass fibers to cause them to melt.  The melting glass envelops part or all of the metal fibers. When the glass cools, at least some of the metal fibers are bound to other metal fibers by the glass. Both the metal and glass fibers can be dispersed in a liquid prior to being mixed together;  and a bonding aid can be added to mixture prior to the heating step to temporarily provide stability to the web to permit processing.

Patent CA-2284769-A1 (CA)
Title: Lock mechanism
Inventor: NEWMAN DONALD JOHN
IPC: E05B17/04
Filed: 1998-04-06
Abstract: The invention is concerned with a lock mechanism of the kind having a deadbolt (9) which is operable by either an inside actuator or an outside actuator. The inside actuator usually includes a turn knob or the like, and the outside actuator usually includes a key operated lock. The lock mechanism includes a gear train (8) through which each of the two actuators is drivably connected to the deadbolt (9). The gear train includes two drive gears (13, 14) which are independently rotatable about a common axis of rotation, and each is connected to a respective one of the two actuators so as to rotate in response to operation of that actuator. The gear train (8) also includes two driven gears (17, 18) which are united to form a single piece composite gear (16), and each driven gear (17, 18) is cooperable with a respective one of the two drive gears (13, 14). The composite gear (16) is connected to the deadbolt (9) so that the deadbolt (9) moves between operative and inoperative positions in response to rotation of the composite gear (16).  Each actuator adopts a rest position when the deadbolt (9) is in the inoperative position, and neither drive gear (13, 14) cooperatively engages with the composite gear (16) when the respective actuator is in the rest position. Furthermore, the gear arrangement is such that the outside actuator turns through 360° to cause the deadbolt (9) to move from one of its positions to the other, whereas 180° rotation of the inside actuator is sufficient to effect the same degree of deadbolt movement.
