Abstract: This invention is a method for preparing an automotive catalyst system. It comprises the steps of providing a substrate, providing a gamma-alumina support material, depositing a lanthana precursor and calcining the precursor, depositing an oxygen storage material precursor like ceria precursor and calcining this precursor material, and subsequently depositing catalytic material like platinum on the oxygen storage material. The alumina may be initially washcoated on the substrate or at any stage after deposition of the lanthana precursor.

Abstract: An air scrubbing system for removing dust produced by longwall shearers from the operator's work area. The system uses a plurality of small scrubbing units mounted on the shearer. Each of the scrubbing units utilizes a series of twin fluid atomizers located at the inlet of the unit to produce a fine water mist for capturing the respirable dust. The scrubbing units return the dust-laden mist to the coal face.

Abstract: A method and apparatus for controlling the dust produced by continuous underground coal mining machinery. The apparatus comprises a wet scrubber mounted on the pivoted boom adjacent the cutting head and discharges the cleaned air into the air curtain flow. The wet scrubber utilizes twin fluid atomizers to reduce the quantity of water required, produce fine water mist, and permit discharge of the dust-laden air directly to the mine.

Abstract: A ladder apparatus and method for use with large construction equipment, such as large tractors, mining trucks and similar vehicles that have an operator's platform or operating station located a substantial distance off the ground. The powered ladder has a fixed ladder portion rigidly attached to such a vehicle. The fixed ladder portion has spacedly attached thereto a frame element upon which a retractable ladder element is slidably disposed. The retractable ladder element is raised and lowered by an electric winch operable from the vehicle's operating station.

Abstract: A method and apparatus for separating particulate pollutants having a size range from submicrons to several tens of microns from a gas stream. The invention utilizes micron sized liquid particles or mists to remove the particles from the gas stream. The apparatus includes twin fluid atomizers to produce the micron sized particles and a corrugated plate interceptor to remove the liquid and entrain particulate pollutants from the gas stream.

Abstract: An apparatus and method for securing a tubular member onto a post extending from the body of a jewelry piece supported at a work station wherein the member is positioned with its axis parallel to a preselected axis at the work station and, in response to the positioning of the member, the post is releasably engaged to align it with the first axis and wherein force is applied between the positioned member and the aligned post, thereby bringing the member into surrounding relationship with the post and causing the post to be released.

Abstract: A practice of severing a length of chain wherein the chain is supported and an interior link of the chain is severed at the link portion which passes through the central opening of an immediately adjacent link.

Abstract: The present invention relates to an improvement in a fountain pen in which the fountain pen is provided with a writing point feed bar and a casing for supporting the writing mechanism, there being a partition located adjacent to the feed bar and having a cylindrical boss extending away therefrom. The cartridge is provided with a double lip interior open end which is adapted to fit over the boss and conduct the ink into the bore that extends through the boss that communicates with the feed bar. The tapered nose end of the cartridge snugly fits into the bore of the casing adjacent the boss that communicates with the feed bar. This not only insures that the lip sealing is forced radially inward and is not disturbed, by also insures that the end of the cartridge engages the partition wall for sealing and the interior wall of the casing for additional sealing.

Abstract: Four bar clamps arranged with slots in the bars interlock to form a rectangular clamping assembly for holding rectangular and box-like members in position for glueing. The bar clamps include adjustable length means between a fixed pressure pad and threaded adjustable pressure pad.
