Abstract: Induction heating systems for metal food cans configured to deliver sufficient heat into the can to sterilize the food within the can are provided. The heating system includes an induction coil and a control system. The control system is configured to monitor and control heating of sealed food cans during induction heating and to control and/or confirm various aspects of can heating during induction heating.

Abstract: A container configured to be stacked adjacent to a second container is provided. The container includes a sidewall having a first end, an end wall having a peripheral edge, a seam coupling the peripheral edge of the end wall to the first end of the sidewall, and an alignment feature coupled to the seam. The alignment feature includes an inner surface. The alignment feature is positioned relative to the seam such that, when the container is stacked adjacent to the second container, the inner surface of the alignment feature contacts an outer surface of a seam of the second container, the contact resisting lateral movement of the container relative to the second container.

Abstract: A self-heating food container configured to hold food and to heat food within the container is provided. The container includes a body wall. A space is defined within the body wall. A chemical heater is located within the space, which upon activation, is configured to generate heat, thereby increasing the temperature of the contents cavity.

Abstract: A container including a sidewall and an end panel is provided. The end panel includes a center panel, an elastic portion, and a frustoconical transition portion. The center panel and the elastic portion are configured to transition between a first configuration and a second configuration.

Abstract: A container adapted to be stacked on top of a second container is provided. The container includes a first end wall and a sidewall having a first end and a second end. The container includes a first seam coupling the first end wall to the first end of the sidewall, the first seam including a shoulder extending inwardly from an outer surface of the first seam. The container includes an alignment feature extending from the shoulder away from the first end wall. The alignment feature is adapted to align the container relative to the second container and to resist lateral movement of the container relative to the second container when the container is stacked on top of the second container.

Abstract: A method of measuring acceleration using an optical sensor. In the optical sensor, acceleration, acoustic velocity, or displacement (vibration) causes a corresponding shift in the center wavelength of the sensor output. The sensor can be coupled to a high-speed interferometric interrogator through an unbalanced fiber interferometer. The unbalanced interferometer functions to translate optical wavelength shift into phase shift, which is easily demodulated by the interrogator.

Abstract: A food or drink container kit includes a metal container including a round threaded neck having at least one integrally formed thread. The kit also includes a metal press-on, twist-off closure comprising a round skirt including a gasket material 5 located on at least a portion of the interior of the skirt, a seal forming between the neck and skirt when the closure is placed on the container and heated.
