Abstract: A laser welding method includes guiding laser pulses to a workpiece surface of workpieces and adjusting a power of the laser pulses according to a time pulse curve to spot weld the workpieces together. The time pulse curve has a first pulse section having a rising pulse flank for generating a melting temperature and subsequently a vaporization temperature in the workpieces, a second pulse section for melt bath generation having a vapor channel in the workpieces, a third pulse section having a pulse flank which initially drops vertically to at least ¾ of the power at an end of the second pulse section and subsequently drops more flatly for reversion of the vapor channel, and a fourth pulse section having a low pulse plateau and a level of between ? and ¼ of the power at the end of the second pulse section for oscillation of the melt.

Abstract: The present invention is a temperature measuring device for insertion into food which audibly signals the user when the temperature of the food reaches a predetermined level. The stem of the device contains a coiled temperature sensitive bi-metallic spring. As the internal temperature of the substance increases, the temperature sensing material slowly rotates, causing a pointer and triggering disk to rotate. When the rotation achieves a predetermined position, a pre-wound coil spring is permitted to engage a drive gear which operates a hammer device so as to provide an audible signal. Thus, the user is audibly alerted when the internal temperature of the substance reaches the desired threshold level.

Abstract: An air filtration system for refrigerated compartments. In one embodiment, the refrigerated compartment of the invention includes a plurality of walls defining the refrigerated compartment, an air inlet passage and an air outlet passage extending through at least one of the walls, a plenum chamber positioned outside of said refrigerated compartment having an air inlet port and an air outlet port wherein the air inlet port and air outlet port are respectively fluidly coupled to the air inlet passage and said air outlet passage, a fan to produce airflow between the air inlet port and the air outlet port, and an air filter assembly disposed within the plenum. The air filtration system of the invention can be utilized in a refrigerated commercial transport vehicle.

Abstract: The present invention describes a refrigerator air filtration system. In one embodiment, the filtration system is positioned outside of the refrigerated compartment. The refrigerated compartment of the invention includes a plurality of walls defining the refrigerated compartment, an air inlet passage and an air outlet passage extending through at least one of the walls, a plenum chamber positioned outside of said refrigerated compartment having an air inlet port and an air outlet port wherein the air inlet port and air outlet port are respectively fluidly coupled to the air inlet passage and said air outlet passage, a fan to produce airflow between the air inlet port and the air outlet port, and an air filter assembly disposed within the plenum. In an alternative embodiment, the refrigerator walls have internal cavities herein forming a plenum chamber in fluid communication with the interior airspace of te refrigerator.

Abstract: The present invention describes a refrigerator air filtration system. The air filtration system includes a microfilter adapted for use within a refrigerator by cooperating with existing air handling means, or in conjunction with a provided air handling means, e.g. a fan. In a preferred embodiment, the filtration system is supplied as a kit which includes the necessary components for use within a plurality of refrigerators as are known in the art. Incorporation of the air filtration system is useful for enhancing food freshness and flavor and further aids in retarding food spoilage.

Abstract: The present invention is a temperature measuring device for insertion into food which audibly signals the user when the temperature of the food reaches a predetermined level. The stem of the device contains a temperature sensitive spring in bi-metallic communication. As the internal temperature of the substance increases, the temperature sensing material and spring slowly rise causing the disk to rotate back to its original position. When the original position is reached, the actuation pin on the temperature pointer activates a series of levers which release a manually pre-wound coil spring. The unwinding of the coil spring activates a large gear which then activates a small gear causing a clapper with a plurality of wings to spin in circles and repeatedly ring a bell. Thus, the user is audibly alerted when the internal temperature of the substance reaches the desired threshold level.
