Patent number: 11930970Abstract: Exemplary power systems for dynamically controlling a dispenser drive motor for dispensing soap, sanitizing or lotion. An exemplary soap, sanitizing or lotion dispenser includes a housing, a receptacle for receiving a container for holding a soap, sanitizing or lotion, a container of soap, sanitizing or lotion and a pump secured to the container. The exemplary soap, sanitizing or lotion dispenser includes a power source, a motor and an actuator that couples the motor to the pump. In addition, the exemplary soap, sanitizing or lotion dispenser includes pulse width modulation circuitry in circuit communication with the power source and the motor. Movement of the actuator one actuation cycle dispenses a dose of soap, sanitizing or lotion. The pulse width modulation circuitry provides a plurality of voltage pulses to the motor to move the actuator one actuation cycle.Type: GrantFiled: November 17, 2022Date of Patent: March 19, 2024Assignee: GOJO Industries, Inc.Inventors: John J.

Patent number: 7955439Abstract: A process for producing an enzyme-resistant starch uses an aqueous feed composition that comprises (i) starch that contains at least about 50% by weight amylose, (ii) water, and (iii) alcohol. The concentration of starch in the feed composition is between about 5% and about 50% by weight, and the pH of the feed composition is between about 3.5 and about 6.5. In a first heating step, the feed composition is heated to a temperature between about 130-170° C. for about 0.1-3.0 hours. The feed composition is cooled to a temperature between about 4-70° C. for about 0.1-6.0 hours. In a second heating step, the feed composition is heated to a temperature between about 110-150° C. for about 0.1-10.0 hours. The starch is separated from the majority of the water and alcohol and is dried.Type: GrantFiled: May 27, 2010Date of Patent: June 7, 2011Assignee: Tate & Lyle Ingredients Americas LLCInventors: Keith D.

Publication number: 20090011082Abstract: A process for producing a starch comprises treating a feed starch that comprises amylopectin with glucanotransferase to produce a chain-extended starch, and treating the chain-extended starch with a debranching enzyme to produce a starch product that comprises amylose fragments. In certain embodiments, the process further comprises, crystallizing at least part of the starch product, heating the starch product in the presence of moisture, treating the starch product with alpha-amylase, and washing the starch product to remove at least some non-crystallized starch, wherein the degree of polymerization of the starch product is increased by increasing the amylose content of the feed starch or is decreased by decreasing the amylose content of the feed starch. The product of this process can have a relatively high total dietary fiber content, a relatively high heat resistance, or both.Type: ApplicationFiled: March 6, 2008Publication date: January 8, 2009Inventors: Donald W.

Patent number: 5378491Abstract: A method or preparing reduced fat foods is provided which employs a fragmented, granular amylose starch having a melting onset temperature (as measured by differential scanning calorimetry) of greater than about 70.degree. C. when measured at 20% starch hydrolysate solids. The fragmented, granular amylose starch hydrolysate is prepared by hydrolyzing a granular amylose starch in a strongly acidic aqueous slurry at a temperature greater than 70.degree. C. or by hydrolysis at a lower temperature followed by heating a slurry, after neutralization, to raise the melting onset temperature. Also provided are food formulations in which the fragmented, granular amylose starch hydrolysate is used to replace fat and aqueous dispersions of the fragmented, granular amylose starch hydrolysate which are useful therein.Type: GrantFiled: July 30, 1992Date of Patent: January 3, 1995Assignee: A.
