  • Patent number: 6719816
    Abstract: An artificial firelog is provided comprising combustible cellulosic material, a combustible wax binder and an amount of sodium bicarbonate effective to reduce emissions of particulate matter (PM) and carbon monoxide (CO). The sodium bicarbonate comprises about 1% to about 10% by weight of the artificial firelog. Preferably, the sodium bicarbonate comprises about 2% to about 5% by weight of the artificial firelog. Besides substantially reducing PM and CO emissions during combustion of the artificial firelog, the undesirable odor associated with combustion of the wax binder is decreased and the firelog's total burn time is extended. Moreover, the sodium bicarbonate increases the “poke resistance” of the firelog making the log suitable for outdoor use and a natural appearing white ash develops during the course of combustion.

  • Patent number: 6602306
    Abstract: An artificial firelog comprising a mixture of combustible materials and a combustible binder further contains particulate coke comprising about 1% to about 35% by weight of the firelog, the coke particles having a size less than about 4 mm, to create a realistic crackling sound that mimics the sounds produced during the burning of natural logs. The particulate coke has a preferred moisture content between about 2% and about 20% by weight. The particulate coke may be combined in predetermined ratios with other established crackle additives including natural additives such as coriander seed to extend the time period during which the burning artificial firelog crackles. Preferably, the particulate coke comprises metallurgical coke.

  • Patent number: 5610126
    Abstract: A lavatory cleansing block is formed of a composition comprising a mixture of (A) a surface active component comprising one or more anionic surface active agents and (B) a halogen release agent component consisting of (i) a halogen release agent selected from N-chloro-succinimide, calcium hypochlorite, chloramine T, dichlorodimethylhydantoin and bromochlorodimethylhydantoin, and, optionally, (ii) another halogen release agent, in which the halogen release component forms from 10 to 65% by weight of the composition, halogen release component (i) forms not less than 5% by weight of the composite and halogen release component (ii), when present, forms not more than 30% by weight of the block.

  • Patent number: 4738728
    Abstract: A lavatory cleansing block is formed of a mixture comprising:(a) from 5 to 85% by weight of one or more anionic surface active agents;(b) from 2 to 50% by weight of one or more solubility control agents having a solubility in water less than that of the anionic surface active agent(s); and(c) from 0.5 to 50% by weight of one or more water-soluble salts of polyvalent metals.
