Abstract: An orbital shaker which provides a shaking motion that is both stable and accurate to allow repeatability is provided, which allows for ease of cleaning of the shaking platform due to its mounting on a drive platform that keeps the entire drive system in an assembled state even if the shaking platform is removed for cleaning. A vibration sensor can also be provided that senses an unbalanced load on the orbital shaker and communicates with the orbital shaker controller to reduce the shaking speed in a pre-determined, trackable manner so that shaking of samples can be continued at a vibration level that is below a threshold value. Additionally, an incubating enclosure can also be provided in which a uniform heat is created throughout the entire incubating chamber in order to assure minimum temperature fluctuations between samples being processed regardless of their position on the shaking platform.

Abstract: An electrically heated water kettle comprises a vessel for holding a liquid for extraction of tea, coffee or other food material. The vessel includes a partially open immersible container sized to allow the passage of water between the walls of the vessel. The container is capable of holding the material while an opening in the container allows the entrance of water into the container upon immersion of the container in the water. The heated kettle incorporates structure to hold the container out of the water until the water reaches an appropriate extraction temperature and to immerse or withdraw the container into or from the water as is necessary to accomplish the extraction.

Abstract: A waffle maker has upper and lower baking plates each of which is powered with at lease one heating element for baking waffle. A power control unit responds to a temperature sensing unit to control power applied to the heaters and to maintain the heating plates both before and after each baking cycle at a manually pre-selected temperature. A manually adjustable timer controls the duration of the baking cycle.
