Patent number: 11588376Abstract: An adaptor is disclosed for connecting a rotating electrical machine 12 to a prime mover 10. The adaptor comprises at least one air outlet. The adaptor is arranged to provide an increase in a cross-sectional area of air flow towards the outlet. In this way part of the dynamic pressure can be converted into additional static pressure rise through steady expansion of the air flow cross-section. This in turn may help to improve the overall amount of cooling air passing through the machine for a given fan input power.Type: GrantFiled: October 13, 2021Date of Patent: February 21, 2023Assignee: Cummins Generator Technologies LimitedInventors: Himanshu Agrawal, Abhishek Kakade, Mark Jason Riley, Robert Mitchell Rolston, Haider Ali Abbas

Publication number: 20100139650Abstract: A burner tube (1) for use in an oven such as a tunnel oven. The burner tube includes a tubular body (2) having an axially extending slot (3) therein and an inlet (6) for combustible gas, the burner tube further including a metal mesh (4) which covers the slot. In use, the burner tube defines a flow path for combustible gas so that combustible gas entering the burner tube at the inlet passes through the slot and exits the burner tube through a flow area of the metal mesh. The flow area of the metal mesh is greater than the area of the slot at the outer surface of the tubular body. In use, a visible flame is anchored to the flow area of the metal mesh and the metal mesh incandesces to produce radiant heat.Type: ApplicationFiled: March 19, 2008Publication date: June 10, 2010Inventors: Michael Pritchard, Robert Mitchell Rolston

Patent number: 6536945Abstract: A heat flux measuring device for transporting through a heated chamber, the device having an array of sensors, each sensor comprising first and second surfaces bounding a region, a thermally insulating layer substantially occupying said region, and means for providing a signal which is a measure of the temperature difference across the layer. The said first surface of each sensor is in thermal contact with a heat sink and the said second surface of each sensor is exposed.Type: GrantFiled: October 1, 2001Date of Patent: March 25, 2003Assignee: United Biscuits (UK) LimitedInventor: Robert Mitchell Rolston

Patent number: 6264362Abstract: Apparatus for and methods of meauring heat flux comprises first and second sensors arranged to pass through an oven in line astern. Each sensor measures the temperature difference across a thermally insulating layer by having one surface of each sensor being exposed to the heat flux, each sensor including thermocouple measuring junctions for measuring the temperature of the exposed surface. The first sensor is radiation-absorbing and the second sensor is reflecting. The apparatus includes additional thermocouple junctions for measuring the gas temperature and a device for recording data from the sensors and from additional thermocouple junctions. The signals from one of the sensors at one instant are correlated with the corresponding signals from the other sensor at a later instant, the time difference being the time taken for one sensor to reach a position formerly occupied by the other sensor.Type: GrantFiled: February 22, 1999Date of Patent: July 24, 2001Assignee: United Biscuits (UK) LimitedInventor: Robert Mitchell Rolston
