Patent number: 6705090Abstract: The present invention comprises an ice harvest system for use in an ice maker. The ice maker herein includes a refrigeration system for cooling of an evaporator. Ice is formed thereon as water is pumped by a re-circulating pump to flow from a water distribution tube over the evaporator surface. Water that is not immediately frozen thereon flows into a water pan positioned there below. A pressure fitting is positioned in the pan at the bottom thereof and connected to a pneumatic tube. The pneumatic tube is connected to a pressure sensor located on a control board at a position remote from the water pan. Pressure is communicated through the tube to the pressure sensor as a function of the depth of the water in the pan. This pressure is converted by a microprocessor of the control board for interpretation as a water level in the pan. As the water level in the tray lowers due to the formation of ice, the pressure transmitted to the pressure sensor reduces from a predetermined high or full water level.Type: GrantFiled: April 15, 2002Date of Patent: March 16, 2004Assignee: IMI Cornelius Inc.Inventors: Gregory M.

Patent number: 6644343Abstract: An electronic control for the operation of a beverage dispenser of the refrigerated ice bank type is shown. The control provides for reliable determinations of when ice production is needed and when it is not needed. A microprocessor receives information from an ice bank probe and from a temperature probe located within the ice bank. Data collected by the microprocessor from both the ice bank probe and the temperature probe is used to determine if the ice bank is either insufficient in size and should be increased or is of sufficient size such that the compressor can be turned off. A carbonator level probe is also shown and connected to the microprocessor. The microprocessor is programmed whereby the carbonator probes are sampled in a manner to accurately determine the level of water in the carbonator and therefore the need for turning on or turning off any water pump connected thereto.Type: GrantFiled: September 16, 2002Date of Patent: November 11, 2003Assignee: IMI Cornelius Inc.Inventors: Timothy W.

Patent number: 6612118Abstract: The ice maker herein works in the conventional manner wherein a refrigeration system provides for cooling of the evaporator. Water is first circulated over the evaporator as the evaporator is cooled. A temperature sensor is located in a water recirculating system and a microprocessor monitors the temperture of the circulating water. Once a predetermined non-freezing temperature is reached, for example 40 degrees Fahrenheit, water circulation is stopped. However, the compressor continues to run and cool the evaporator for a predetermined period of time to a desired lower temperature. The pump is then turned on and water again circulated over the evaporator initiating the ice making cycle. This process insures that ice adheres to the evaporator and does not prematurely slough off and/or result in the formation of slush.Type: GrantFiled: February 6, 2002Date of Patent: September 2, 2003Assignee: IMI Cornelius Inc.Inventors: Gregory M. Billman, Donald E. Wiley, Jr., Kyle B. Elsom

Patent number: 6572326Abstract: The present invention comprises a cart loading machine that provides for improved operating efficiencies, and includes a cart loading station, an infeed conveyor, a pattern forming area, a carrier sheet and wiping mechanism, and a fork loading apparatus. The cart loading station includes a framework defining a cart loading position and a cart waiting position. With the carrier in its extended position having carried a fully formed pattern to the cart loading position, a wiping mechanism is extended from beneath the carrier plate to contact the bundles as they sit on the carrier so that when the carrier moves back to its retracted position, the bundles are blocked and stripped therefrom. The wiping mechanism is then retracted below the carrier to permit the loading of a subsequent pattern of bundles thereon. This wiping mechanism eliminates the need for an overhanging blocking mechanism thereby permitting more efficient loader design and easier access to the pattern forming and bundle stripping areas.Type: GrantFiled: April 21, 2000Date of Patent: June 3, 2003Assignee: Cannon Equipment CompanyInventors: Hugh I.
