Abstract: Methods and systems are provided for preparing a gelatin-based product. In one example, a device for preparing the gelatin-based product includes a mixing chamber, a first liquid reservoir fluidically coupled to the mixing chamber, and a chiller module. The device further includes a slideable tray including a number of slots for receiving a number of fluid vessels and an injection assembly fluidly coupled to the mixing chamber and positioned vertically above the tray.

Abstract: An improvement is provided to a pressurized close-cycle machine that has a cold-end pressure vessel and is of the type having a piston undergoing reciprocating linear motion within a cylinder containing a working fluid heated by conduction through a heater head by heat from an external thermal source. The improvement includes a heat exchanger for cooling the working fluid, where the heat exchanger is disposed within the cold-end pressure vessel. The heater head may be directly coupled to the cold-end pressure vessel by welding or other methods. A coolant tube is used to convey coolant through the heat exchanger.

Abstract: A device and method for equalizing the pressure between work-space and crankcase in a pressurized engine, such as a Stirling engine. The device consists of a two-way valve connected between the work-space and the crankcase. The valve is connected to the work-space with a passageway including a constriction to provide an mean pressure for monitoring purposes. The valve connects the work-space and crankcase allowing the pressure to equalize when the mean pressure of the work-space exceeds the crankcase pressure by a predetermined amount.
