Appl. No.:

12/814005

Inventors:

William Webster - Portland ME, US
David Gallant - Newfield ME, US

Assignee:

Novia Products LLC - Portland ME

International Classification:

A24F 25/00

US Classification:

239 34, 239 35, 239 36, 239 37, 239 50, 239 57

Abstract:

An ambient environment modification mechanism such as a scent dispenser (which could also act as a filter) which may comprise a piston and a piston cylinder, receiving the piston, and forming a piston cylinder chamber volume when the piston is moved from an inserted position in the piston cylinder to a withdrawn position in the piston cylinder. The piston may have a hollow interior receiving an ambient air modification material holder, such as a cartridge, containing ambient air modification material. The hollow interior may be in fluid communication with the piston cylinder chamber volume at a first end of the hollow interior. A ventilation opening may be in fluid communication with the hollow interior at a second end of the hollow interior. A piston cylinder chamber volume forming mechanism, such as spring may move the piston relative to the piston cylinder from the inserted position to the withdrawn position.

Abstract:

A urine pH indicator has a plurality of hydrophilic, non-ionic, polymer foam carrier particles. The carrier particles are impregnated with an indicator complex having more than one chromophore and indicating more than one pH threshold via at least three distinguishable colors. The carrier particles are preferable chopped and soaked in a solution containing the chromophore complex. Upon evaporation of the solvent, the chromophore complex is bound to the carrier particles which can then be spread upon animal litter to receive urine and indicate pH via color display.

International Classification:

C04B 100

US Classification:

106 85

Abstract:

Strong dense shaped articles such as pellets suitable for use as gravel substitutes are produced by the described method from solid fly ash-containing water materials obtained by a lime based dry scrubbing flue gas desulfurization operation. In this method the dry ash-containing waste powder, which also contains calcium sulfite or sulfate reaction products and unreacted lime, is first uniformly contacted with a critical amount of water and then immediately compacted at a critical compaction ratio to provide a handleable green body in which the fly ash particles are positioned with respect to one another so that the interstitial spaces are sufficient to accommodate the volumetric changes in wthe cementitious materials without any deleterious expansion of the article as the article is cured.

Appl. No.:

6/547943

Inventors:

William R. Webster - Fredericksburg VA

Assignee:

Allied Paper Incorporated - Kalamazoo MI

International Classification:

B32B 3112

US Classification:

156 69

Abstract:

The present invention relates to a glue-free method for sealing closures to paperboard food containers, and also to the novel closures for such method. The present invention is particularly applicable to containers for moisture sensitive food items such as salt, and is characterized in the use of a thermoplastic vinyl chloride ethylene copolymer which functions both to provide a heat seal and effective resistance to moisture vapor transmission. The copolymer has sufficient slip to permit handling of the closures in automatic forming and heat sealing equipment.

International Classification:

B23P 1904

US Classification:

29705

Abstract:

Apparatus and method for removing, installing and/or testing valve-spring retainer assemblies of internal combustion engines and the like employ an existing spark plug opening to mount a tool which is designed to depress a valve spring and thereby disengage an associated valve-spring retainer assembly. Once it has been disengaged, at least a portion of the valve-spring retainer assembly can be removed from a cylinder head of the engine through the tool.

David Gallant - Newfield ME, US

International Classification:

A61L 9/12

Abstract:

A scent dispenser/absorber includes a pair of cylindrical housing members arranged coaxially about a common longitudinal axis such that the inner housing member is rotatably received in an interior chamber of the outer housing member. Each housing member has a peripheral sidewall provided with a set of radially extending apertures. A scent cartridge is removably disposed within an interior chamber of the inner housing member to absorb undesirable odors, or to emit desirable scents. By manually controlling the relative rotational positions of the housing members, a user can align or misalign the two sets of apertures, thereby enabling or disabling the transfer of scents or odors between the scent cartridge and the surrounding environment.
