Abstract: A grain-popping machine and associated pod-based popping method is disclosed. The grain-popping is configured to receive a pod. Each pod includes a plurality of cells, with each cell preferably containing a single grain kernel or seed, flavoring, and a cooking medium such as oil or shortening. In a preferred embodiment, the pod is loaded into the grain-popping machine through a slot so that it is held in position below a heating element. The heating element is activated to begin a popping sequence. When each grain kernel or seed in the pod reaches popping temperature, it absorbs the flavoring in its cell and ejects through the bottom of the pod, which is weakened to ease ejection, into a bowl positioned in a receiving area of the grain-popping machine. The pod is then removed and disposed of.

Abstract: A method and a device for monitoring laser cutting processes in the high-power range above 1 kW mean output envisage automatic quality control after interruption and/or completion of a cutting process carried out with predetermined cutting parameters. The cutting process is interrupted after a first partial processing step, whereupon a partial section (K1 . . . KX) of the processing path is scanned. This preferably takes place at a higher speed than that for the first partial processing procedure and preferably close to or on the same processing path. On the basis of the scan result at least one quality feature of the processing result is automatically determined and compared with predefined quality specifications. Depending on the result of the comparison a fault message can then be issued, the processing interrupted, reworking of a defect point carried out, at least one cutting parameter adjusted and the cutting process continued with the changed set of cutting parameters.

Abstract: An HVACR fan and heater assembly accounts for the cyclonic flow produced by centrifugal blowers by placing a heater vertically and biased towards a side of a fan cabinet in order to increase and balance airflow through the heater, eliminating hot spots and fire risk and improving heater efficiency. A blockoff in the fan cabinet forces airflow within the cabinet to move through the heater. The positioning of the heater may vary depending on the direction of rotation of the centrifugal blower. The fan and heater assembly may further include baffles to direct the airflow from the centrifugal blower.

Abstract: An induction humidification system is disclosed. The induction humidification system includes a base having a circumferential induction coil and a removable and replaceable cartridge received within the interior space defined by the induction coil. The canister has a nonmetallic housing, such as a plastic housing, within which a ferromagnetic member having a circumferential sidewall is disposed. When the canister is received within the base, the ferromagnetic member sidewall and the induction coil are radially overlapping such that a current applied to the induction coil causes the ferromagnetic member to be heated which in turn causes water held within the canister to be converted to steam. Once the ferromagnetic member has reached the end of its useful life, the canister can be simply replaced with a new canister that can be received by the original base.
