Title: Method and apparatus for acoustically enhancing the cooling of clinker
Inventor: SANTSCHI MARK
IPC: F27D25/00
Filed: 1995-07-18
Abstract: A method and apparatus for acoustically enhancing cooling of molten liquid.  In one embodiment, a cement plant has a mill in which raw materials are mixed and ground into a powder, a kiln in which the powdered raw material undergoes a calcining process and is converted into a molten liquid known as clinker, a cooler for cooling and solidifying the clinker, and a finishing mill for grinding and mixing the clinker with gypsum and/or other raw materials.  The clinker cooler has a transport mechanism for transporting clinker from an inlet end to an outlet end and a plurality of fans, located below the transport mechanism, for blowing air up through the transport mechanism and into the bottom surface of the clinker bed.   The clinker cooler has one or more horns positioned on the roof of the cooler for emitting acoustic energy into the cooler.   A controller controls activation of each horn independently, such that each horn may be operated continuously or intermittently.  Emission of acoustic energy into the cooling chamber of the clinker cooler creates turbulence in the air and molten liquid flowing  in  the  cooler,  thereby  enhancing  the  cooling process.   The increased turbulence and energy within the cooler  assists  breaking up  of  the  solidified  clinker, thereby enhancing contact between the clinker surface and air.

Abstract: A tray having a peripheral flange with one or more raised ledges to secure a pair of membranes to enclose the tray. A lower membrane may be attached to a first ledge of the flange. An upper membrane may be attached to a second ledge or a recessed lip of the flange without connection to the lower membrane, except through the tray. The two attachment surfaces may be separated by a trough or by being positioned on different levels to facilitate trimming of the upper membrane in a continuous manufacturing process. A method and apparatus for modified atmosphere packaging uses a rotary conveyor to transport a plurality of trays to be packaged between a plurality of stations in a circular arrangement.  The trays may be loaded onto a receiving platform by depositing them over movable beds which can reciprocate downwardly in order to permit the trays to be removably held inside slots in a removable platform. Since the platform is removable from the conveyor, it may be centered in any particular station by lifting the platform from the conveyor and guiding it into a precise alignment at a particular station. The package may then be filled, its atmosphere replaced with one lower in oxygen content, and then the desired atomosphere sealed within the package. This can be done in the continuous fashion so that the film is severed from a continuous web. A package, packaging method, and packaging apparatus for facilitating the packaging of large meat products and exchanging the ambient atmosphere to establish a desired gaseous atmosphere that extends the shelf life of the product. The package includes a pair of preformed relatively rigid plastic domed or cupped members which abut along a sealing surface. The upper (318) and lower (310) package portions include flanges (312, 336) which are adapted to facilitate not only the formation of the package but its subsequent opening. A reciprocatable filling tube (330) maintains the separation between the upper and lower package portions to permit gas exchange and then may be reciprocated downwardly to allow the upper package portion to abut atop the lower package portion for sealing connection.

Patent CA-2167851-A1 (CA)
Title: Dual self-operating fishing tool
Inventor: SCOTT ROBERT LINDSAY
IPC: E21B31/12
Filed: 1996-01-25
Abstract: The pump jack at a producing petroleum well actuates a steel rod which extends down the length of the well tubing to a bottom hole pump. There are two types of rod; (1) non-continuous round rod which is assembled in 32 foot lengths, and (2) continuous tapered elliptical rod, which is extended and recovered from a reel. Both types of rod are currently in use; the continuous elliptical rod is a more recent design and is gradually replacing the more common but older round rod. Occasionally the rod will break and the broken extension must be recovered from the well casing. This is done with a recovery tool which is dispatched down the well casing on the end of a recovery tubing to "fish" out the bottom segment of the broken rod. Present recovery methods use a recovery tool (commonly referred to as an "overshot" or "fishing" tool), which was designed for round rod and is not ideally suited for elliptical rod because the tool gripping mechanism does not conform to the elliptical cross section of the rod. Recovery attempts often fail using the present methods, particularly on elliptical rod. Failures usually mean that the entire well casing may have to be recovered at some considerable expense and down-time for the well. The tool discussed in this application is an improvement on the current tool which makes recovery operations much more reliable and faster. It does not rely on the technological methodology of the present recovery tool, but rather uses a superior concept which assures highly reliable performance under all conditions. It is specifically designed for recovery of elliptical rod, but is also completely suitable for recovery of round rod. The key to the superior performance of this tool is that it provides for equal distribution of tensile force around the diameter of the rod shaft. This prevents breakage of the rod, or the tool, or both, from distortions in the distribution of pulling force. This is achieved through the use of: (1) self-locking "slips" which conform to the diametrical profile of the rod and will not allow release of the rod even if the tool itself fractures from excessive tensile pull, and (2) the use of a shoe guide specifically designed to align the elliptical or round rod within the clenching cavity of the locking slips, and (3) the interchangeability of the guide sleeve and locking slips for recovery of either round rod or elliptical rod.

Title: Minimum propellant, zero momentum spacecraft attitude control system
Inventor: SHANKAR UDAY JAYA
IPC: B64G1/24
Filed: 1996-02-19
Abstract: A zero-momentum spacecraft's attitude is controlled by determining the torque required about a control axis to maintain the desired attitude, and, during each of recurrent control cycles, enabling a magnetic torquer if the torque demand exceeds a threshold.  During each of the control cycles, thruster(s) are enabled to make up the difference between the torque demand and the estimated torque produced by the magnetic torquer.  In determining the torque demand, the attitude rate signal is low-pass filtered to reduce noise, and the control loop bandwidth is maintained by totalling the estimated torque applied by the magnetic torquer and thrusters, integrating and high-pass filtering the estimated torque signals, and adding the filtered estimated torque with the filtered attitude rate signals to generate low-noise attitude rate signals.  A three-axis system is described.

Title: Free form fabrication of metallic components
Inventor: BAMPTON CLIFFORD C
IPC: B22F1/10
Filed: 1996-06-12
Abstract: A method of free form fabrication of metallic components, typically using computer aided design data, comprises selective laser binding and transient liquid sintering of blended powders. The powder blend includes a base metal alloy, a lower melting temperature alloy, and a polymer binder that constitutes approximately 5-15% of the total blend. A preform part is built up, layer-by-layer, by localized laser melting of the polymer constituent, which rapidly resolidifies to bind the metal particles. The binder is eliminated from the preform part by heating in a vacuum furnace at low atmospheric pressure. The preform part may require support during elimination of the polymer binder and subsequent densification by controlled heat treatment. Densification is performed at a temperature above the melting point of the lower temperature alloy but below the melting point of the base metal alloy to produce transient liquid sintering of the part to near full density with desired shape and dimensional tolerances. The densified part may be subjected to a final hot isostatic pressing (HIP) treatment to close residual porosity and complete the chemical homogenization of the part. Elimination of residual porosity improves fatigue properties of part, and homogenization improves ambient temperature ductility, toughness, and high temperature strength. An advantage of the process is rapid production of complex shaped metal prototypes and complete small batch production runs of high cost metal components without special tooling or machining operations.
