Patent number: 8323598Abstract: Compositions are provided, derived from chemical treatment of carbonaceous fiber felt forms or other carbonaceous substrates, that exhibit both high efficiency and capacity for mercury capture from flue gases and the like. These compositions are superior to known compositions, particularly with regard to their performance under severely deactivating conditions. The compositions result from the pyrolysis of certain specific sulfur bearing compounds while in contact with activated carbon powders, activated carbon fibers, or with other carbonized forms. Precursor compounds to these novel mercury-binding compositions contain structural moieties that may be represented as: where X, Y are individual atoms or are functional groups consisting of several atoms, such that the atom bonding to sulfur is not hydrogen. X and Y can be linked in cyclic structures, either directly or through other atoms.Type: GrantFiled: September 6, 2011Date of Patent: December 4, 2012Assignee: Gore Enterprise Holdings, Inc.Inventors: Vincent A. Durante, Zhengtian Xu, Glenn S. Shealy

Patent number: 6779459Abstract: Pyrotechnic fireworks launch apparatus is provided. The apparatus includes a base to which is affixed a male-configured launching cylinder adapted to accept thereover, in combination, an internally cylindrical, female-configured projectile, wherein the projectile has a proximal and a distal end thereof. The projectile houses a fused pyrotechnic display charge proximate its distal end and also houses a fused launching charge encased therein and partitioned from the display charge. On insertion of the launching cylinder into the proximal end of the projectile, thereby mounting the projectile upon the launching cylinder, the encased launching charge and the launching cylinder are in abutting relationship. Upon ignition of the fused launch charge, the projectile is launched vertically from the launching cylinder. The external configuration of the projectile may have any number of shapes. In a preferred configuration, it is shaped as a rocket.Type: GrantFiled: July 2, 2002Date of Patent: August 24, 2004Assignee: Hunter Pacific LimitedInventor: John A. Werner

Patent number: 6718882Abstract: A sparkler for use as a fireworks display is provided. The sparkler has an extended spark display time, burning and emitting sparks in one direction initially followed by the spark progression reversing direction and then burning while emitting sparks in the reverse direction. The sparkler construction provides inner and outer sheaths of a flammable spark composition separated by an insulating layer of a fire resistant material. The inner and outer layers are in contact with one another at one end of the sheath, to permit ignition of the inner flammable composition by the progressing spark. Especially preferred is a construction of the aforesaid sparkler which emits sparks of one color upon the initial burn and sparks of a different color upon the reverse burn. Also provided is a process for the manufacture of these novel sparklers.Type: GrantFiled: October 31, 2002Date of Patent: April 13, 2004Assignee: Hunter Pacific LimitedInventor: Qui Fu Sheng
