Abstract: The invention concerns a method and device for controlling a distillation or condensation apparatus including a distillation vessel, heat source and condenser. A distillation or condensation apparatus consumes considerable quantities of cooling water which is discharged, through a length of hose connected to the condenser, directly into the drain. The aim of the invention is to propose a method and device for controlling a distillation or condensation apparatus to ensure a significant reduction in cooling-water consumption. The method proposed achieves this by virtue of the fact that the cooling water flowing through the condenser of the distillation or condensation apparatus is passed round in a closed loop, its temperature is measured in this loop and, when an upper temperature limit is reached, cooling water is replaced by feeding in cold water until a lower temperature limit is reached.

Abstract: A programmable remote control transmitter has a programming mode and a controlling mode and is used to control electric devices such as television sets. The remote control transmitter has a memory for storing a limited number of remote control codes. There is a keypad for selecting one of the stored codes and a transmitter for transmitting the remote control signal corresponding to the selected remote control code to the electric device such as a television set. Remote control codes are able to be input to the memory of the remote control transmitter only when the remote control transmitter is in programming mode. In normal operation the remote control transmitter is in controlling mode. A removable key must be used to change the mode of the remote control transmitter from controlling mode to programming mode.

Abstract: An adjustable magneto-rheological fluid device includes a movable piston adjacent a first chamber containing a first hydraulic fluid for moving the piston. The first hydraulic fluid interacts with a flexible magneto-rheological compartment containing a magneto-rheological fluid that flows between a first magneto-rheological fluid chamber and a second magneto-rheological fluid chamber. By controlling the flow of the magneto-rheological fluid, the device controls the first hydraulic fluid in the first chamber to bias the piston in a first direction. Additionally, the magneto-rheological fluid device may include a second chamber, containing a second hydraulic fluid, spaced apart from the first chamber on the opposite side of the piston. The second hydraulic fluid interacts with the flexible magneto-rheological compartment allowing the device to control the second hydraulic fluid to bias the piston in a second direction opposite the first direction.
