Filed:

Nov 14, 2008

Appl. No.:

12/271397

Inventors:

Sung K. Cho - Arlington TX, US

Assignee:

Tacony Corporation - Fenton MO

International Classification:

A47L 7/00

US Classification:

15320, 153272, 15347

Abstract:

A portable extractor apparatus is shown which includes a wheel mounted base having a solution tank for dispensing and recovering cleaning solution. A cleaning head communicates with the solution tank and contacts the surface to the cleaned for dispensing and recovering cleaning solution. A fluid pump circulates cleaning solution in a path between the solution tank and the cleaning head. A vacuum motor provides a vacuum source for the cleaning head for suctioning the surface being cleaned. The solution tank has mounted thereon both an initial multi-component filter assembly which initially filters incoming solution being circulated to the solution tank and a distinct final filter component which removes smaller particles from the solution being re-circulated from the tank. The solution tank bottom wall has a profile which improves the efficiency of the final filter component.

Appl. No.:

11/121548

Inventors:

Sung Cho - Arlington TX, US

International Classification:

A47L 11/30

US Classification:

015321000

Abstract:

A cleaning tool head for use with the wand of a carpet extractor. The head includes a housing that engages a surface being cleaned and forms an enclosed interior. A partition divides the interior into a vacuum chamber located a front sidewall of the housing and a cleaning chamber located behind the vacuum chamber. The cleaning head is mounted on a pair of transport wheels which extend along a wheel axis and is further supported by an upwardly extending handle assembly. The cleaning head is pivotable in an arcuate path about the wheel axis through movement of the handle assembly between a cleaning position in which the housing lower edge engages the surface to be cleaned as the handle assembly is pulled by a user and a transport position in which the lower edge is out of engagement with the surface to be cleaned as the user pushes the handle assembly.

International Classification:

A23L 1/312

US Classification:

426574

Abstract:

A method of manufacturing a gelatin shape collagen food, which contains a tendon structure therein, is provided. The method is comprised of: 1) boil tendons from a cow in water for 90 minutes, 2) quench the tendon with cold water at 15 C., 3) rip off meats from the tendons, 4) slice the tendons in a shape with a 5 mm thickness, 1 cm width and 10 cm length. At the same time 5) boil cow's pettitoe in water for one hour, 6) rip off skin of the cow pettitoe and remove fats by hand, 7) boil the cow's pettitoe again in water for 30 minutes to remove residual fat, 8) mix the sliced tendons and ripped off pettitoe in water in 1:1:4 volume ratios, add caramel drop, gelatin powders and apple cider, 9) boil down the mixtures prepared in the eighth step slowly for 1.5 hours, 10) put the mixture in a mold and quench as soon as possible, 11) dry out the gelatin structure by blowing air at room temperature for four hours, and 12) cut the gelatin structure into desired size.

H04L 29/06

Abstract:

A method of creating an interactive application network includes displaying, by a processor, a workspace and a toolbox on a display screen, instantiating, by the processor, a first interaction container to display a first output in response to a first user input, instantiating, by the processor, a second interaction container to display a second output based on the first output, in response to a second user input, the second user input being a user interaction with the first interactive container, and linking, by the processor, the first interactive container with the second interactive container via an interactive link to form the interactive application network.
