Patent number: 8870548Abstract: Systems and methods for maintaining substantially a baseline pressure in a chamber of a pumping apparatus are disclosed. Embodiments of the present invention may serve to control a motor to compensate or account for a pressure drift which may occur in a chamber of the pumping apparatus. More specifically, a dispense motor may be controlled to substantially maintain a baseline pressure in the dispense chamber before a dispense based on a pressure sensed in the dispense chamber. In one embodiment, before a dispense is initiated a control loop may be utilized such that it is repeatedly determined if the pressure in the dispense chamber is above a desired pressure and, if so, the movement of the pumping means regulated to maintain substantially the desired pressure in the dispense chamber until a dispense of fluid is initiated.Type: GrantFiled: October 3, 2011Date of Patent: October 28, 2014Assignee: Entegris, Inc.Inventors: James Cedrone, George L.

Patent number: 8606397Abstract: A grain distributor including a timer coupled to a distribution spout that generates a series of particular time values. The control processor is programmed with an algorithm to pivot the distribution spout and to receive and record signals from the sensor as the sensor confronts each of the code clusters and each of the proof windows. The control processor is programmed with the algorithm to associate each signal from each code cluster with a particular time value generated by the timer and to memorize the particular time value associated with each code cluster in a long term memory and the control processor being programmed with the algorithm to associate each signal from each of the proof windows in a long term memory. The grain distributor is also self programming.Type: GrantFiled: December 3, 2012Date of Patent: December 10, 2013Assignee: Schlagel, Inc.Inventor: Bill Schlagel

Patent number: 8590741Abstract: A dispenser for a flowable medium, such as soap, foam soap or the like, has an outlet opening on the underside, a sensor in the region of the outlet opening, which sensor emits an electrical signal upon sensing a person, and an electrical pump which is caused to dispense a portion of the medium through the outlet opening as a result of the electrical signal from the sensor. A switch is also provided on the dispenser, the operation of which switch causes the next signal from the sensor to emit an optical or acoustic signal instead of dispensing a portion of the medium.Type: GrantFiled: November 5, 2010Date of Patent: November 26, 2013Inventor: Hans Georg Hagleitner

Patent number: 8584901Abstract: A powder dispensing apparatus for dispensing a powder either with or without a liquid is presented. The apparatus includes a base, a dispenser, and a tower. The base is adapted for receiving a container. The dispenser includes a rotatable carriage contacting a support element with an opening. The carriage includes a plurality of compartments horizontally disposed above an optional funnel and rotatable about a central axis. A hopper is disposed above the carriage and communicates with less than all compartments. Each compartment is capable of separately dispensing a powder from the hopper through the opening into the funnel and thereafter into the container resting on the base. The tower is disposed between and attached at opposing ends to the base and the dispenser. The apparatus is useful, for example, in preparing baby formula and other food for infants, as well as in preparing food and drink for children and adults.Type: GrantFiled: August 3, 2011Date of Patent: November 19, 2013Assignees: Product Spring, LLC, Taylored Concepts, LLC, Hartdesign!

Patent number: 8573443Abstract: The present invention is a universal touch free dispenser for dispensing selective amounts of product from varying sized hand pump product containers. There is a touch free sensor on the front of the dispenser and in electrical communication with the drive assembly of the dispenser. An extendable ram pad extends from the drive assembly that is adjustable according to the amount of product a user wishes to be dispensed. With the product container placed within the dispenser, the unit is adjusted such that the pump on the container is in contact with the dispenser ram. When an object is placed within the viewing range of the touch free sensor, a signal is sent to the drive assembly and the dispenser ram is extended thereby depressing the pump head and dispensing the product onto the object.Type: GrantFiled: March 5, 2011Date of Patent: November 5, 2013Inventor: Mark R.

Publication number: 20130264355Abstract: A motion-activated soap dispenser is provided having a vertically directed motion detector and a vertically oriented dispensing stream of hand cleaning solution. The device comprises a counter or wall mounted housing having a reservoir of hand soap or hand sanitizer that is ejected in short bursts in an upward direction and onto a user's palm placed over a top-mounted motion sensor. The reservoir is a refillable liquid container that is pumped for its contents, or alternatively the reservoir is a replaceable cartridge of compressed hand cleaning solution that utilizes internal pressure to eject the contents therefrom. The solution is routed through a conduit and into a nozzled aperture along the upper portion of the housing, whereby the solution is dispensed in liquid or foam consistency. An electric motor and timer circuit controls the burst of dispensed fluid from the reservoir, upon activation by the motion detector change in state.Type: ApplicationFiled: April 8, 2013Publication date: October 10, 2013Inventor: Michael Jodoin
