Abstract: A guide-ring comprises a graphite body and a mechanically attached insert, preferable made of metal. The insert and body form a guide ring supporting a split neck-ring used during glass container manufacturing. The graphite body avoids the need for separate lubrication while being sufficiently strong enough to enable mechanical attachment of the insert. The combination provides the structural integrity needed to resist damage during glass container manufacturing operations and the thermal properties needed to contact hot glass gobs.

Abstract: Repositionable stacker bar pads composed of a relatively high-strength nonmetallic material have tongue-in-groove adjoining surfaces and glass-contact surfaces which are roughsned or serrated. The high strength material and overlapping tongue-in-groove "footprint" allows rigid and reliable attachment to a metal support structure. The rough finish of the glass-contact surface minimizes thermal checking and other hot-glass article problems.

Abstract: The emissions of nitrogen dioxide and ammonia from cooling towers in geothermal power plants are controlled by contacting the steam condensate used as make-up water for the cooling tower with a zeolite or other molecular sieve to remove ammonia and/or ammonium ions from the condensate before it is passed into the cooling tower.

Abstract: A fire fighting vehicle provides the capability to access obstructed areas, to quickly connect to fire water sources, to discharge large amounts of water and/or foam to fight major industrial fires, and to be capable of repositioning while fighting these fires. The vehicle is adapted from a boom truck chassis and mounts a large flow rate capability fire monitor in a position to provide maximum orientation flexibility.

Abstract: A hydrocarbon conversion catalyst useful for converting hydrocarbon feeds to midbarrel products is prepared by extruding a mixture of an inorganic refractory oxide component and a crystalline aluminosilicate zeolite having cracking activity to form extrudates which are broken into particles normally ranging in length between 1/16 and 1/2 inch. The extruded particles are then calcined in the presence of steam at a water vapor partial pressure greater than about 2.0 p.s.i.a., preferably greater than about 5.0 p.s.i.a. The calcination step is carried out in the presence of sufficient steam for a sufficient amount of time at a sufficient temperature to convert the crystalline aluminosilicate zeolite in the extrudates into an ultrahydrophobic zeolite having a unit cell size between about 24.20 and about 24.45 Angstroms and a sorptive capacity for water vapor less than about 5 weight percent of the zeolite at 25.degree. C. and a p/p.degree. value of 0.10.

Abstract: The selectivity of a midbarrel hydrocracking process for middle distillates is significantly increased by using a catalyst containing a Y zeolite that has been exchanged with rare earth cations. The rare earth-exchanged Y zeolite has a unit cell size below 24.45 angstroms and/or a water vapor sorptive capacity less than 10 weight percent at 25.degree. C. and a p/p.sub.o value of 0.1.

Abstract: The buildup of heavy polynuclear aromatic compounds in a hydrocracking system is controlled by contacting at least a portion of the recycle oil to the hydrocracker with a porous solid that has been treated with an acid. The porous solid serves as a support for the acid, thereby presenting the recycle oil with a high surface area for contact with the acid, which extracts the heavy polynuclear aromatic compounds from the recycle oil. A preferred acid-treated support is an amorphous silica that has been impregnated with sulfuric acid.

Abstract: A hydrocracking process using a catalyst containing a hydrogenation component, zeolite beta, and between 1 and 15 weight percent of a Y zeolite having a unit cell size less than about 24.40 angstroms.

Abstract: A reactivated catalyst having optimum activity for hydrocracking and other acid catalyzed chemical conversion processes is prepared by contacting its deactivated counterpart, which contains a crystalline molecular sieve, a Group VIII noble metal hydrogenation component and carbonaceous deposits, with a gas containing molecular oxygen, preferably air, at a temperature between 950.degree. and 1200.degree. F., preferably between about 1050.degree. and 1150.degree. F., for a time sufficient to remove at least a portion of the carbonaceous deposits. When the reactivated catalyst contains a dealuminated Y zeolite that has been ion-exchanged with both noble metal and rare earth metal cations, its activity for hydrocracking in an ammonia-deficient atmosphere can be further increased by a rejuvenation procedure in which the reactivated catalyst is contacted with an aqueous ammonia solution in which an ammonium salt has been dissolved.
