  • Patent number: 7874459
    Abstract: An apparatus for dispensing soft serve frozen food product, such as soft serve ice cream and the like, provides the ability to select the fat content or other characteristic of the ice cream dispensed from the machine.
    Type: Grant
    Filed: September 14, 2007
    Date of Patent: January 25, 2011
    Inventor: John Harra
  • Patent number: 7681761
    Abstract: Soft serve frozen food such as ice cream and frozen yogurt is pumped from a sanitary reservoir into a closed loop flow path that includes an emulsion barrel assembly that intimately mixes the ingredients in the food composition into a smooth consistency frozen food product. A dispensing head allows servings of soft serve food to be withdrawn from the closed loop. A clean-in-place system permits all critical parts of the machine that come in contact with food to be cleaned and sanitized without having to take the machine apart.

  • Patent number: 4931321
    Abstract: Fibrous and gelatinous vegetable matter is liquefied and frozen so as to result in a frozen food composition which is dripless and cohesive when exposed to temperatures above its melting point and which has reduced fat and cholesterol content. A preferred vegetable matter is edible rhubarb leafstalks. Various flavoring agents may be added to the vegetable matter. The frozen food composition closely approximates the characteristics of high grade ice cream. Even closer approximation to ice cream may be obtained by using dairy products as flavoring agents.

  • Patent number: 4622752
    Abstract: A gauge for determining whether a conductive element, such as a cutting element, fence, gauge rod, gauge shaft, or guiding surface is oriented at a predetermined angle with respect to a reference surface is disclosed and claimed. The gauge includes an indicator, an electrical energy source, and at least one pair of contacts. When the gauge is placed on the reference surface, the contacts are abutted against the conductive element, and the conductive element is oriented at the predetermined angle, a series circuit is completed between the indicator and the energy source. As one example, the gauge can be used to ascertain the angle of a saw blade with respect to a saw table.
