Abstract: An ice maker includes a refrigeration system, a water system, and a control system. The control system includes an air fitting disposed above the sump of the water system, a pneumatic tube, and a controller including a processor and an air pressure sensor. The air fitting defines a chamber in which air may be trapped and includes one or more openings through which water in the sump is in fluid communication with the air in the chamber. The pneumatic tube is in fluid communication with the air pressure sensor and the air fitting. The air pressure sensor is adapted to sense a pressure corresponding to a sump water level. The controller is adapted to control the operation of the refrigeration system and the operation of the water system based upon the sump water level. To avoid errors in water level measurements due to temperature changes, the system uses the pressure sensor data's noise level to detect when the water level reaches the bottom of the air fitting.

The double helical coil has an inlet and an outlet disposed at a bottom end and a plurality of external radial fins spaced apart along a length thereof. The burner is centered in the double helical coil and disposed above the inlet and the outlet. The containment structure has a closed bottom end and a flue opening at an upper end. The containment structure is positioned above the inlet and the outlet to enclose the double helical coil and the draft-type burner. The burner heats the continuous tube to evenly transfer heat to the fluid while the fluid flows through the continuous tube from the inlet to the outlet.

Abstract: A sump for use in an ice maker, the sump adapted to hold a mass of water, wherein the ice maker freezes some or all of the mass of water into ice. The sump includes a recirculation area and one or more additional areas separated from the recirculation area. The recirculation area and the one or more additional areas are in fluid communication via one or more passageways. The recirculation area is adapted to hold and receive a first portion of the mass of water having a first mass. The one or more additional areas are adapted to hold a second portion of the mass of water having a second mass. Thus, if the first portion of water forms into slush, the second portion of water can be recirculated to melt the slush.

Abstract: An ice bagging system that comprises a compressed flake nugget ice maker and an ice bagging device that receives compressed flake nugget ice dispensed from the ice maker. The ice bagging device includes at least one bag into which the compressed flake nugget ice is dropped. The ice bagging device is configured to seal and drop the bag of compressed flake nugget ice once a predetermined quantity of ice has been loaded into the at least one bag. An ice merchandiser supports at least the ice bagging device. The ice merchandiser is adapted to receive the at least one bag of compressed flake nugget ice dropped from the ice bagging device. Whereby the compressed flake nugget ice is dispensed from the ice maker directly to the bag of the ice bagging device and the at least one bag of compressed flake nugget ice is dropped directly from the ice bagging device into the ice merchandiser.

Abstract: A blending assembly that comprises a blender base that has an actuating member and a control mechanism, and a container that is removably mountable on the blender base. The container has an integral dispensing spout and dispensing valve. The dispensing valve opens and closes the dispensing spout. The container is adapted to receive ingredients. The control mechanism operates an impeller of the container to blend the ingredients and operates the actuating member to engage the dispensing valve to move the dispensing valve between open and closed positions with respect to the container, thereby opening and closing the dispensing spout for dispensing the blended ingredients.

Abstract: An ice making has an ice making mold with a plurality of ice making cells opened at the bottom, a water tank, water spray nozzles adapted for spraying the water contained in the water tank towards the ice making cells, an ice bin adapted for storage of ice cubes formed in and harvested from the ice making cells, and an inclined plate having water spray openings and recovery openings and mounted between the ice making mold and the water spray nozzles. The ice making cells are each attached to a serpentine evaporator tube, which is cooled by a refrigeration system and also heated by way of electrical pulse energy. The electrical pulse heating of the ice making cells allows ice to be quickly and efficiently harvested from the cells.

Abstract: An in-car navigation system (1) which, in response to a user query, outputs a modified list of results aimed at making it easier for a user to locate the intended result. In one aspect, the navigation system selectively merges together different matching results. In another aspect, the system decides which fields from each matching entry should be displayed in the results list so that the displayed results may be easily differentiated from one another by the user. In a further aspect, the system provides a country- or region-specific address presentation format so that a user may be presented with a full address in a manner which is typical of the country or region in which the address is found.

Abstract: A commercial ice making machine having an electronic monitoring device which captures the operating status and production history of the ice machine. The ice production history of the machine is communicated via telephony and/or the Internet on a regular recurring basis to a remote computer. The production history is used to generate invoices to the user of the ice machine, so that the user is charged based on his or her actual ice consumption. Failure of the ice machine is detected by the monitoring device and communicated immediately to a service company so that the ice machine can be repaired before the end user realizes the machine has failed.
