Abstract: A continuous blending system can be used to prepare burner fuel or blasting agent, and includes a mixer, a first hydrocarbon system, a second hydrocarbon mixer, and a computing system. The mixer is configured for continuously mixing a continuous supply of a first hydrocarbon and a continuous supply of second hydrocarbon to provide a mixed hydrocarbon at a flow rate and a predefined ratio of first and second hydrocarbon. The first hydrocarbon system provides a continuous flow of first hydrocarbon into the mixer. The second hydrocarbon system provides a continuous flow of second hydrocarbon system into the mixer. The computing system is in communication with and configured for simultaneously controlling the first and second hydrocarbon systems in order to obtain the mixed hydrocarbon at the predefined flow rate and at the predefined ratio of first and second hydrocarbon.

Abstract: An x-ray tube window cooling assembly (11) for an x-ray tube (18) includes an electron collector body (110). The electron collector body (110) is thermally coupled to an x-ray tube window (102). The electron collector body (110) may include a coolant circuit (112) with a coolant inlet (114) and a coolant outlet (122). One or more thermal exchange devices may be coupled to the x-ray tube window (102) or to the coolant circuit (112) and reduce temperature of the x-ray tube window (102).

The electron collector body (110) includes a coolant circuit (112) with a coolant inlet (114) and a coolant outlet (122). Multiple thermal exchange devices are coupled to the coolant circuit (112) and reduce temperature of a coolant passing through the exchange devices.

Abstract: A dual purpose article carrier includes a backpack with a concealed garment stored under a flap or panel of the backpack. The backpack has a handle for carrying, shoulder straps and a waistbelt for supporting and distributing the weight of the contents of the backpack. The panel is at least partially removable for deployment of the garment and is preferably attached and secured between the garment and the backpack.

Abstract: This invention includes a method and apparatus for vending frozen foods and also for vending hot previously frozen foods. The invention includes the use of a microwave oven, and a delivery system that maintains the food in an upright orientation so as to prevent spilling of hot foods. An important feature is that the invention does not destroy the microwave containment integrity of the microwave oven and therefore is safer from a radiation perspective.
