Abstract: Method and apparatus for treating confined material such as buried waste or areas of contaminated earth by injecting a plurality of high velocity jets of treating fluid into the material over a limited depth in multiple direction from each of a plurality of injection holes. The high velocity jets remain stationary, but the arrangement of the jets emanating from an injection hole in multiple directions produces a result similar to a rotating jet but with increased penetrating force. The jets are operated sequentially over the limited depth of each injection hole to treat a layer of the material and are then moved and again operated sequentially over another limited depth of each injection hole to provide treatment of the material by layers. This allows effective treatment of material surrounding each injection hole without substantial interference from treating fluid flowing through the material from a previously treated hole.

Abstract: An apparatus and method for treating chemical production plant process condensate such that a contaminant-rich stream and a relatively pure aqueous stream is separately recoverable from the condensate, wherein the contaminants are substantially removed from the condensate by steam stripping and subsequent rectification in a relatively low pressure stripping/rectification tower. The tower overhead is then condensed, and any non-condensed gases are subjected to water scrubbing to further recover contaminates from the non-condensed gas. A portion of the condensed overhead and scrubbing water containing contaminates is returned to the top of the rectification section of the tower as reflux and the balance being withdrawn as a concentrated stream for reuse in the plant. The apparatus may be used in conjunction with existing low pressure equipment, avoiding costly major modifications, and is particularly adapted to use in conjunction with ammonia and methanol plants.

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.

The rotor includes multiple vanes with shrouds on opposite ends thereof. Seal rings are mounted upon inner surfaces of the end plates and biased towards outer surfaces of the shrouds to maintain a sealed relation between the shrouds and end plates. An expandable biasing tube is mounted proximate the seal rings to bias each seal ring toward and against the shroud. Each biasing tube is hollow to receive a predetermined amount of pressurized air.

Abstract: An instrument mounting bracket for the control yoke of an aircraft. The mounting bracket includes a main body having a C-shaped configuration which is intended to receive the yoke. Mounted to the main body is a presser plate which acts in conjunction with the main body to grip the yoke therebetween. The main body also includes a pair of threaded attachment holes, with one hole being normal to the plane of the C-shape and the other being within such plane. Either hole may receive a threaded shaft having an enlarged section. An extension arm which includes a mount for the instrument is provided with a through hole for the threaded shaft. Passing the shaft through the extension arm and tightening it within one of the attachment holes secures the extension arm to the main body, and permits angular adjustment of the arm with respect to the body. The extension arm may thus be positioned such that the instrument mount is located in front of the yoke handles, readily accessible to the user.

The second support bar is moved between the recess pair in upper support members to the recess pair in the lower support members depending upon the alignment of the shoe rack horizontally or vertically. Each side frame includes a plurality of support members to support a plurality of rod pairs for storing a large number of shoes.

Abstract: A method of plugging holes, in particular the plugging of drill holes in earth. The method consists of inserting an auger, having a bit at the lower end and a central rod about which is formed a helical land, into the drill hole and rotating the auger to cause material to be conveyed upward and out of the drill hole. As the auger is moved downward this will cause any plugs or debris within the hole to be removed. After the auger has been inserted to a sufficient depth the rotation of the auger is reversed, and bentonite or other plugging material is poured into the drill hole about the auger. The reversed rotation of the auger will cause the plugging material to be conveyed downward along the drill hole and compacted at the bottom. As the drill hole is filled with compacted plugging material the auger is slowly removed to form a consistent reliable plug of the plugging material. A second method utilizes a tubular capsule filled with coarse ground sodium bentonite.

Abstract: A gas filtration system which includes a primary separator for removing a majority of a particulate material from a gas stream. The primary separator discharges a filtered gas stream which retains a portion of the particulate material. The filtered gas stream from the primary separator is delivered to a secondary particulate source which introduces additional particulate material into the filtered gas stream to produce a conditioned gas stream containing primary and secondary particulate material. The output of the secondary particulate source is delivered to a secondary filter which removes the primary and secondary particulate material from the conditioned gas stream to output the resulting gas stream, substantially void of particulate material. The conditioned gas stream contains a minimum amount of particulate material necessary to achieve optimal efficiency and operating life within the secondary separator.
