摘要:
A stirring hot plate for simultaneously heating and stirring a mixture includes a phase controlled motor that spins magnets which couple to, and thereby spin, a stir bar within the mixture. In addition to spinning the magnets, the motor includes an operational mode in which the motor is rapidly braked thereby quickly spinning down the stir bar. The stirring hot plate also includes a visual indicator to the user that the platform is hot-to-the-touch that is especially effective when the stirring hot plate is not in use.

Controls for stirrers, hot plates and stirring hot plates provide respective user interfaces having a single control knob that is used to provide a plurality of setpoints. The control permits a user to pause a stirring operation of stirrers and stirring hot plates, unload a vessel, load a new vessel, and restart the stirring without having to re-enter a speed setpoint. Also, current operational parameters may be stored as preset setpoints. The control further permits a user to program a calibration temperature that is similar to the temperatures expected to be encountered during operation.

摘要:
A hotplate with a stainless steel top plate to support a vessel. The stainless steel top plate has an upper surface with a substantially centrally located depression having a depth and area generally sufficient to absorb upward crowning of the top plate when heated. A heating unit is in a heat transfer relation with the stainless steel top plate, and a base unit is connected to the heating plate assembly; however, the base unit is not fastened directly to the stainless steel top plate, so that the stainless steel top plate can expand more uniformly when heated.

A pair of shorter range radio frequency networks may be linked together using a longer range communication protocol that is not based on the same radio frequency protocol utilized by the shorter range radio frequency networks. Enumeration data from one of the shorter range networks may be exchanged over a longer range network to combine the two shorter range networks using proxy devices such as cellular telephones. This may allow devices in a shorter range network to communicate over a longer range.
