Abstract: A water treatment system is described in which an inlet is in fluid communication with an outlet. A first region including a halogen release system is located downstream from the inlet and upstream from the outlet. A second region including chitosan or a chitosan derivative is located downstream from the first region and upstream from the outlet. A filter including a housing containing the water treatment system is also described. A method for treating water in which water flows through the water treatment system is also described.

Abstract: A filter to provide potable water may generally comprise an inlet in fluid communication with an outlet, a halogen release system intermediate the inlet and the outlet, a filter material comprising chitosan or a derivative thereof intermediate the halogen release system and the outlet, and a scavenger barrier intermediate the filter material and the outlet. The filter material may comprise a chitosan-halogen complex. The filter material is capable of regeneration during periods of stagnation. The filter may have a Log reduction value for viruses of at least 4 and a Log reduction value for bacteria of at least 6.

Abstract: The water treatment systems may generally comprise multiple halogens and chitosan or derivatives thereof as well as methods of making and using the same. A water treatment system to provide potable water may generally comprise an inlet in fluid communication with an outlet, a halogen release system intermediate the inlet and the outlet, and a halogenated chitosan intermediate the halogen release system and the outlet. The system may comprise a scavenger barrier intermediate the halogenated chitosan and the outlet. The halogen release system may comprise a first halogen having a first oxidizing potential. The halogenated chitosan may comprise a second halogen having a second oxidizing potential. The second oxidizing potential is greater than the first oxidizing potential.

Abstract: The present invention discloses a system for leveling the mattress used in trucks of the type including tractor trailers used in cross country trucking and also for travel trailers and recreational vehicles. The present invention discloses a rigid frame that can be placed under a mattress. A plurality of lifting devices attached to the rigid frame can be raised or lowered individually or in designated groups as needed to make the top surface of the mattress level.

Abstract: The present invention discloses a system for leveling the mattress used in trucks of the type including tractor trailers used in cross country trucking and also for travel trailers and recreational vehicles. The present invention discloses a support slab for placement under the mattress having one end of the support slab being elevated and thereby leveled by an inflatable cylindrical air chamber which air chamber is inflated by a small electric air pump which is operated off of the vehicle's power system. The air chamber would have a plurality of chambers wherein each chamber could be inflated to a variable pressure to allow further leveling of the mattress in the lateral directions.

Abstract: An ice making machine is provided which includes an ice making section; an ice discharge port connected to the ice making section for receiving ice made in the ice making section; an ice storage section for storing ice produced in the ice making section; an ice delivery chute interconnecting said ice discharge port the said ice storage section; and an ice storage level detecting apparatus including an ice storage level sensor disposed in the ice delivery chute proximate an outlet end of said ice delivery chute. An ice storage level detecting apparatus for an ice making machine is also provided which includes an ice storage level sensor, a housing to receive the ice level storage sensor, the housing adapted to be affixed within an ice delivery chute of an ice making machine at or adjacent an outlet of the ice delivery chute.

Abstract: An ice cube dispenser for compressed ice flakes includes an ice cube source and an ice storage bin disposed adjacent the ice cube source. The ice storage bin has an arcuate bottom surface and at least two sides thereof. The arcuate contours are provided where the at least two sides join the arcuate bottom surface. An agitator is disposed within the ice storage bin wherein the agitator comprises a first ice agitator arm rotating on a shaft. The first ice agitator arm defines a radius when the shaft is rotated. The radius corresponds to a radius of the arcuate bottom surface and one of the arcuate contours of the ice storage bin. The first agitator arm has a shape which corresponds to a shape of the one of the arcuate contours between one of the at least two sides and the arcuate bottom surface.

Abstract: A beverage cooling system has an ice storage bin having a mechanical agitator disposed therein. The ice storage bin includes an opening at a bottom portion thereof, and the mechanical agitator is actuable to mechanically agitate ice in the ice bin and mechanically force ice through the opening. An ice guide is disposed adjacent the opening in the ice storage bin. A cold plate is disposed adjacent the ice guide. The cold plate has an inclined upper surface thereof and includes at least one beverage line disposed underneath the upper surface. The ice guide is positioned to deflect and guide ice onto the inclined upper :surface of the cold plate, wherein the ice is moved along the upper surface by mechanical force provided by an actuation of the agitator.
