  • Patent number: 5152524
    Abstract: A golf accessory device (A) includes a pair of lateral arms (10, 12) which extend laterally beyond a main body (C) for supporting grips (20) of a golf club handle above the ground. Inclined planar grip supporting surfaces (16) are provided for frictionally retaining the golf grip. Prongs (D) provide a stable anchor into the ground for the device and also a divot tool. A bore (40) formed in the free ends of the lateral arms provides a carrier for golf tees (44) and a bore (46) secures a ball marker (50). A simple compact device is provided which may be conveniently carried and used by a golfer for providing multiple functions.

  • Patent number: 4872233
    Abstract: The present invention entails a street sweeper having a drag shoe assembly secured to each side of the street sweeper for confining dirt, debris, etc. Each drag shoe assembly includes an upper frame structure and a drag shoe coupled to the upper frame structure via two generally parallel interconnecting coil spring links. In the event the drag shoe encounters a lateral obstruction while the street sweeper is turning or moving laterally in any way, the coil spring interconnecting links will flex and enable the drag shoe to move laterally back and forth to avoid damage to the drag shoe or frame structure of the street sweeper.

  • Patent number: 4839026
    Abstract: Sulfur oxides are removed at least partially from the gaseous regenerator effluent of a fluid catalytic cracking unit operated with feedstock containing sulfur compounds and converted to hydrogen sulfide in the cracking zone by associating sulfur oxides in the gas with at least one rare earth compound, preferably cerium or a rare earth mixture rich in cerium, supported on discrete particles of alumina. The alumina particles may be a component of particles of a composite fluid cracking catalyst or separate fluidizable entities other than cracking catalyst and physically admixed with the catalyst particles.

  • Patent number: 4493902
    Abstract: This application discloses novel fluid catalytic cracking catalysts comprising microspheres containing more than about 40%, preferably 50-70%, by weight Y-faujasite zeolite, methods for making such catalysts, and the use of such catalysts to crack petroleum feedstocks, particularly those containing large amounts of contaminant metals. The microspheres of the catalyst of the invention are characterized by a combination of desirable catalytic and physical characteristics, including exceptionally high activity, excellent hydrothermal stability, good to excellent attrition resistance, and desirable selectivity characteristics.

  • Patent number: 4430199
    Abstract: High gas and coke make due to contamination of a zeolitic fluid cracking catalyst by metal species such as nickel and vanadium during a cracking process is reduced by adding a phosphorus compound to the process. When the catalyst already contains a metals passivating agent or such agents are used in the cracking process further significant reduction in gas and coke make is realized without significant increase in regenerator temperature by adding additional phosphorus.

  • Patent number: 4325813
    Abstract: This invention provides an improvement in the operation of an FCCU such as to maintain the octane rating of the gasoline fraction from the cracker at a high level over repeated cycles of cracking charge and regeneration by using fresh zeolitic catalyst particles having an alkali metal oxide less than about 1.5% (based on the zeolite content) and controlling the amount of alkali metal oxide that comes into contact with catalyst inventory throughout cracking, stripping and regeneration so as to maintain alkali metal oxide content of equilibrium catalyst below 2.0%, based on the weight of zeolite in the fresh zeolitic catalyst.

  • Patent number: 4235753
    Abstract: An improved process for the production of mechanically strong shaped crystalline zeolitic aluminosilicate bodies from precursor bodies composed of kaolin clay calcined at elevated temperature, the crystallized bodies having essentially the same size and shape as the precursor bodies. Conversion of the calcined clay contained in the precursor bodies to a mixture of crystalline zeolitic alluminosilicate component and a porous amorphous silica-alumina component takes place as a result of reaction between the calcined clay and an aqueous alkaline liquid in which the bodies are immersed. The improved process features the presence of a solution of aluminosilicate nucleation centers during such reaction.

  • Patent number: 4157375
    Abstract: Zeolite catalyzed reduction of nitrogen oxides in exhaust gases is conducted with catalytic elements in the form of multi-channel structures in which parallel channels are defined by thin walls constituted by refractory oxides having zeolite dispersed therein and accessable to diffusion from surfaces of the channel walls. Such structures, preferably monolithic honeycomb forms, are prepared by calcining extruded or cast forms or kaolin at elevated temperatures and treating the calcined kaolin honeycomb with a caustic solution to develop a desired zeolite within the wall members and etch the wall surfaces to provide diffusion paths to and from the embedded zeolite.
