Abstract: A laser beam reflected by wax crystals is used in determining the wax crystallization temperature of a hot dewaxing solvent upstream of solvent chillers. This is automatically achieved by an on-line method from a remote control point, in which a slipstream of solvent is passed through an attached solvent loop into a sample chamber in the loop, without being exposed to ambient conditions. As the sample is cooled, the beam reflections are detected and indicate the wax to crystallization temperature. Corrective measures can then be taken to prevent fouling of the chillers, if need be.

Abstract: A plurality of washing machines each include a washing tub and a chemical tank therein. Each of the chemical tanks is linked by an equalizing conduit at the lower end thereof so as to maintain the same level of fluid within each of the tanks.

Abstract: A vertical axis clothes washing appliance is configured to meet predetermined energy and water usage factors by establishing a balance between water temperature, water level, and wash performance parameters. In accordance with the overall invention, additional controls for the washing machine enable an energy saving hot wash cycle to be established, with this wash cycle being designed to automatically establish a wash temperature which is intermediate warm and hot water temperature settings.

Abstract: A method of programming and controlling an automatic cycle of a clothes dryer provides that, after positioning of a selection dial, a motor associated with the selection dial is rapidly moved to a predetermined location at a constant speed, while the time to do so is measured. With the rotational velocity being known, the exact, initially setting position of the dial is determined in advance.

Abstract: An apparatus and system for permitting dual-mode configuration of an appliance control board preferably in conjunction with an external electronic programming device or by means internal to the appliance. Preferably, a set of selection switches are provided in an interior space of the appliance that are used to select desired operating parameters. By changing the setting of the switches, the operator may configure the appliance for many specific modes of operation. In addition, the appliance can be electronically reconfigured by use of a hand held data probe.

Abstract: A data acquisition system having setup duplication capability so that the setup or portions of the setup of one appliance can be duplicated onto other appliances by electronic means without affecting the identity of each appliance. More particularly, a method and apparatus are provided for effecting a setup record change throughout a plurality of appliances. A first appliance communicates with an external probe that has a memory including at least a first and a second buffer. The setup record of the first appliance is stored in the first buffer. A second appliance is then communicated with through use of the probe and its setup parameter of the setup record buffer, then at lest one setup parameter of the setup record stored in the second buffer is replaced by a setup parameter of the setup record stored in the first buffer to create a new setup record and the contents of the second buffer are transmitted to the second appliance.
