摘要:
A control panel used in combination with a power unit to control the operation of a sauna. The control panel is equipped with a microprocessor that has software and proper circuitry to allow a user to use buttons to input information into the control panel regarding the time, temperature, and day on which heating within the sauna is to occur. Additionally, the power unit has a microprocessor with a pulse width modulation output that causes individual heating elements to continuously produce varying intensities of heat in order to maintain a consistent desired temperature, and/or intermittently radiate heat creating a wave of heat to be emitted by each individual heating element.

In one embodiment, a parallel batch reactor generally includes a plurality of reactor vessels and a plurality of valves configured to allow flow into the reactor vessels when a gas is supplied to the reactor at a pressure higher than a pressure within the reactor vessels and restrict flow from the reactor vessels. A method includes inserting chemical components into the reactor vessels, supplying a first gas to the reactor vessels to pressurize the reactor vessels, stopping supply of the first gas, and supplying a second gas to the reactor at a lower pressure than a pressure within the reactor vessels. The second gas passes through the valves and into the reactor vessels when the pressure within the reactor vessels drops below the pressure of the second gas.

The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl amine or a heteroaryl-amine compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene.

In one embodiment, a parallel batch reactor for effecting chemical reactions includes a plurality of reactor vessels for receiving components of a reaction, an inlet port for receiving pressurized fluid, and a plurality of valves configured to transfer fluid from the inlet port to the reactor vessels and fluidically isolate one or more of the reactor vessels from at least one of the other reactor vessels. The reactor further includes a pressure monitoring system comprising an array of pressure sensors configured to sense pressure in the reactor vessels. Each of the pressure sensors is aligned with one of the plurality of reactor vessels and located external to the reactor vessels and fluid passageways in fluid communication with the reactor vessels.
摘要:
A combinatorial method for discovering or optimizing materials is disclosed. The method uses solution-based components that are mixed and dispensed into regions on a substrate for drying and/or heat-treating. The drying and/or heat-treating produces materials that can be tested for a desired property.

The present invention relates to a control circuit for a whirlpool bath or pool. The control circuit is used to deliver water and/or air to outlet jets in a water-filled pool such as is typically used for hydrotherapy massage. The control circuit includes a pool with a water compartment, a plurality of air jets and water jets in the pool and in communication with the compartment. A water pump connects to the water jets. A rotary valve is interposed between the water pump and the water jets. The rotary valve can be rotationally operated to sequentially provide water to the water jets. Thus, a pattern or a wave can be established from the water jets. An air pump is also provided and connected to the air jets by a manifold and a three-way valve. The manifold is connected to the water jets by a plurality of conduits. Check valves are provided to prevent water from getting into the air system. The three-way valve allows air to be supplied and drawn into the water jets by venturi action.

A control circuit for a sauna compartment has an electrical heater therein connected to a control circuit. The control circuit allows a high voltage to flow through a first heating circuit to permit ambient air in the compartment to reach a first high temperature, at which time voltage is provided to the heater only through the second heating circuit and thence to the heater so that the ambient air in the compartment will maintain said first high temperature to prevent a person in the sauna compartment from feeling immediately chilled when the first high temperature is reached and voltage through the first heating circuit ceases to move to the heater. The method of heating a sauna compartment and controlling the temperature therein involves placing an electrical heater in a sauna compartment; connecting the heater to a source of electrical energy; connecting a control circuit to the heater including first and second heating circuits with each circuit adapted to provide first and second voltages to the heater; sequentially allowing a high voltage to flow through the first heating circuit to permit the ambient air in the compartment to reach a first high temperature, at which time a voltage is provided to the heater only through the second heating current and thence to the heater so that the ambient air in the compartment will maintain said first high temperature to prevent a person in the sauna compartment from feeling immediately chilled when the first high temperature is reached and voltage through the first heating circuit ceases to move to the heater.
