Patent CA-2039074-A1 (CA)
Inventor: BLAND ALAN E
IPC: C04B18/06
Filed: 1991-03-26
Abstract: WDP\16046-11095.abs PELLETIZING ASH     Abstract The invention includes a method for pelletizing ash from a  fluidized  bed  combustor  in  which  limestone  particles  are suspended in the presence of carbonaceous fuel being burned.  Lime-containing bed ash ("FBCR") is produced in the combustor, and fly ash ("FBC fly ash") is generated as a by-product of the combustion process.  The method includes the step of obtaining FBCR and FBC fly ash generated during the combustion process.  Water is added to the FBCR so as to convert a substantial portion of the lime to hydrated lime.  Water is added to the FBC fly ash and pellets are formed from the FBC fly ash.  The FBC fly ash pellets are coated with the hydrated FBCR.  The coated FBC fly ash pellets are cured in a curing silo for a minimum of 6-10 hours, preferably by nesting them in a bed of hydrated FBCR.   The cured pellets then are separated from the bed of hydrated FBCR.  New pellets are formed by mixing the separated, hydrated FBCR with FBC fly ash and water.          The pellets formed with the separated, hydrated FBCR contain about 0-80% by weight of FBCR and about 100-20% by weight of FBC fly ash.          Agglomeration of the pellets in the curing silo is prevented by coating the pellets with hydrated FBCR.  Agglomeration also can be prevented by spraying newly formed pellets with certain chemicals, by drying their surfaces, or by coating the pellets with inert materials other than hydrated FBCR.

Inventor: STONE VERNON E
IPC: E21B33/16
Filed: 1991-09-10
Abstract: A method of cementing oil well casings and a cementing tool used when performing the method are provided. A novel top cementing plug functions in a conventional manner during proper oil well casing cementing operations, but if inserted into the oil well casing in error, allows cement to be pumped through it. The top plug includes an outer, hard rubber casing having vertically spaced fins formed about its circumference. A central passage is provided through the outer casing and receives a cylindrical, metal sleeve. In one embodiment, a bore is formed in a portion of the metal sleeve to define a shoulder within the sleeve. The bore receives a cylindrical housing which carries a spring loaded, ball valve mechanism. The valve mechanism includes an annular spring, retainer which rests on the shoulder.  One end of a helical spring within the housing contacts the retainer while the other end of the spring biases a ball against an annular flange at the top of the housing to seal the passage. The ball moves into the housing and compresses the spring when an increased pressure is applied to the top of the ball thereby opening the passage. In a second embodiment, the bore formed in the cylindrical sleeve is reduced in depth but still defines a shoulder. A burst plate sits on the shoulder to block the passage in normal operation. The burst plate is designed to rupture under increased pressure to open the passage, but maintains intact in normal operation.

Abstract: METHOD AND APPARATUS FOR MONITORING PARAMETERS OF COATING MATERIAL DISPENSING SYSTEMS AND PROCESSES BY ANALYSIS OF SWIRL PATTERN DYNAMICS     Abstract of the Disclosure:         A coating material dispensing system that dispenses coating material onto a substrate in a moving pattern or fiber is provided with a monitor that senses a medium such as sound near the space between the dispensing device nozzle and the substrate, and extracts information relating to the pattern motion, and generates a signal representative of characteristics of the motion of the pattern in the space.  One or more transducers extract the information, and the extracted information is analyzed, preferably by comparison of a frequency spectrum of the signal with a spectrum of standard signal, to detect deviations in the system operation from desired criteria, and optionally, to control parameters of the system.  In another embodiment, plural spaced transducers detect the phase or orientation of the moving pattern and remove background noise, by inverting, summing, multiplying, and otherwise combining the signals. The invention is useful for detecting malfunctions of the system components, for real-time closed loop control of the process, and for quality control inspection of dispensing device components during manufacture.

Abstract: Movement of a fluid such as air is produced by rotating about a rotational axis  (O-O)  a plurality of flow generating plates (P, P1, P1a, P1b, P2, P3) arranged parallelly  with  clearances  (CL)  therebetween.    The clearances  (CL)  between  adjacent  two  flow  generating plates  for  producing  the  movement  of  the  fluid  most effectively only by adhesion of the fluid to the flow generating  plates,  is  set  as  follows.   That  is,  the clearances  (CL)  are set to be twice a value  (c)  of a distance of an intermediate portion between the surface of the flow generating plate contacting a portion of the fluid in a close boundary layer which  is  rotated and moved  substantially  together  with  the  flow  generating plate  and  a  remote  fluid  boundary  layer  which  is substantially not influenced by centrifugal force due to the rotation of the flow generating plate.   In the case of air, the clearances are about 0.5 mm.  It is preferred to form the flow generating plate so as to have a waved surface for improving the flow generating efficiency.

Title: Process for producing composite vibration-damping materials
Inventor: EGUCHI KUNIHIKO
IPC: F16F9/30
Filed: 1992-02-18
Abstract: ABSTRACT OF THE DISCLOSURE composite vibration-damping materials having a resin layer sandwiched between two metal sheets can be produced by reacting prepolymers with low-molecular weight compounds having functional groups capable of reacting with the functional groups in said prepolymers to form covalent bonds and handling the resulting crosslinked resin in such a way that it is sandwiched between the two metal sheets. In accordance with the first embodiment of the invention, two low-molecular weight compounds having different numbers of functional groups per molecule are used; in accordance with the second embodiment, two prepolymers having different numbers of functional groups per molecular chain are used; and in accordance with the third embodiment, a mixture of a first prepolymer and a low-molecular weight compound is coated on at least one surface of two metal sheets and then a second prepolymer is dusted over the coated surface nonuniformly, followed by compressing the two metal sheets together. The thus produced composite vibration-damping materials not only exhibit satisfactory damping performance over a broad temperature range but also develop high adhesive force between the resin and metal sheets at both ordinary and elevated temperatures. In addition, good spot weldability can be imparted to the damping materials by incorporation of an electroconductive filler.

Title: Railway car underbody structure and method
Inventor: KRUG JOHN A
IPC: B61D5/06
Filed: 1992-03-09
Abstract: Abstract of the Disclosure An improved railway car underbody support structure and method for economically constructing same.  The structure includes a center still assembly having a pair of vertically disposed side plates spaced equidistant from the longitudinal center line of the car body and extending from a coupler longitudinally inboard to a wheeled truck assembly.  The truck assembly carries two laterally spaced side bearing members for bearing the load of the car body during lateral tilting of the car body.  One of the improved features is a unitary metal member cut from an economically patterned metal plate.  The unitary members, which are themselves free of any weld lines which may crack under the extreme loads exerted on railway cars, are welded to the underside edge of a respective side plate and welded together beneath the center line of the car body.  The unitary members act as, 1) a bottom side flange to stiffen the side plates, 2) a bottom cover plate to help integrate the sill and 3) as a bottom bolster support which extends over a respective side bearing member. The invention also features a mini-bolster inwardly spaced from the main bolster to distribute the car body load through the sill assembly; a unique side plate upper edge configuration and weld line placement; and a pair of reinforcing bars welded beneath the end of the car body on the inside vertical surfaces of respective side plates; all to provide improved structural underbody integrity and performance.
