Patent number: 10893774Abstract: A milk frothing apparatus which includes a steam probe which consists of an inner steam tube surrounded by an outer tube spaced annularly from the inner tube with a nozzle mounted on the end of the outer tube adjacent the outlet end of the inner tube. The air gap between the inner and outer tubes insulates the outer tube from the heat generated in the inner tube during the steam cycle. By using stainless steel the milk does not stick to the cool outer tube surface and no cleaning of the outer surface of the probe is necessary. The steam itself keeps the inner surfaces of the probe clean.Type: GrantFiled: July 18, 2016Date of Patent: January 19, 2021Inventor: William Westmore Purton

Patent number: 10271679Abstract: A milk frothing apparatus which includes a steam probe; a jug and jug support; a sensor to determine the depth of milk in a jug. The steam probe or jug support is movable preferably driven by stepper motor, to maintain the tip of the probe below the milk surface. A temperature sensor monitors the temperature of the milk in the jug. A micro controller is programmable to start the process; maintain the position of the steam probe relative to the milk surface, stop the process when the milk reaches a desired temperature and maintain records of the number of cycles and a measure of the quantity of milk treated. By using a sensor to measure the distance to the milk surface in a jug the tip of the steam probe can be maintained at the appropriate distance below the milk surface by moving the jug relative to the probe or preferably moving the probe. The process can be more precisely controlled by sensing the milk temperature and ensuring that the process is completed before the milk becomes too hot.Type: GrantFiled: April 10, 2014Date of Patent: April 30, 2019Assignee: William Westmore PurtonInventor: William Westmore Purton

Patent number: 6726205Abstract: A playing card integrity checker utilises a blue light source to illuminate the playing face of each card to use template matching to identify the value and suit of each card based on stored templates from cards of the same card manufacturer. This information and the number of cards counted is matched against the cards needed for a predetermined game. The absence of required cards or the presence of superfluous cards is reported. Cards that have their faces reversed or appear marked are also reported.Type: GrantFiled: August 15, 2000Date of Patent: April 27, 2004Assignee: VendingData CorporationInventor: William Westmore Purton

Patent number: 6629894Abstract: A card inspection device includes a first loading area adapted to receive one or more decks of playing cards. A drive roller is located adjacent the loading area and positioned to impinge on a card if a card were present in the loading area. The loading area has an exit through which cards are urged, one at a time, by a feed roller. A transport path extends from the loading area exit to a card accumulation area. The transport path is further defined by two pairs of transport rollers, one roller of each pair above the transport path and one roller of each pair below the transport path. A camera is located between the two pairs of transport rollers, and a processor governs the operation of a digital camera and the rollers. A printer produces a record of the device's operation based on an output of the processor, and a portion of the transport path is illuminated by one or more blue LEDs.Type: GrantFiled: August 15, 2000Date of Patent: October 7, 2003Assignee: Dolphin Advanced Technologies Pty Ltd.Inventor: William Westmore Purton
