An electrosurgical pencil includes an adjustable-length suction tube which surrounds a stationary electrode to evacuate smoke and electrosurgical byproducts from a surgical site. An electrode anchor unit is located within the interior of the suction tube to allow relative movement of the suction tube relative to a stationarily-retained electrode, and to receive and connect to different lengths of the electrodes. Adjusting the length of the suction tube relative to the different lengths of the electrode achieves effective evacuation, among other things.

Alternatively, a partially pervious drainage blanket is provided in lieu of the impermeable layer where the base is partially pervious. Backup rainwater runs off the drainage blanket horizontally after it saturates the soils of the base.

In the method of the present invention an evacuation mode is presented in an elevator system, which receives destination calls i.e. operates in accordance with so-called destination control. In the method the destination floor calls given on the evacuation floors of the building are changed in the event of an exceptional incident such that the destination floor becomes an exit floor of the building. In the method the elevator car is filled as full as possible on one floor and the travel time to the exit floor is minimized by directing the elevator car to the escape floor without intermediate stops. The passengers to be evacuated are shown information relating to the evacuation on a display located on the destination call panel and / or inside the car of the evacuation elevator.

A dispenser for viscous materials has a housing with a moveable wall that divides the interior volume of the housing into a distal product chamber and a proximal pressure chamber. An outlet from the product chamber is located adjacent to the distal end of the housing and an air inlet is provided to allow air to enter the pressure chamber. Displacement of the product occurs when accumulated excess air pressure in the pressure chamber acts on the back of the movable wall. The excess air pressure is built up by a bellows assembly arranged in fluid communication with the pressure chamber. On actuation, the bellows can be reduced in volume and subsequently recover by entry of air through the inlet. The direction of force application is preferably perpendicular to the housing axis and the location of the bellows is preferably distant from the product outlet.

The invention relates to measuring devices of an electrostatic Fourier transform mass spectrometer and measurement methods for the acquisition of mass spectra with high mass resolution. The measuring device includes electrostatic measuring cells according to the Kingdon principle, in which ions can, when appropriate voltages are applied, orbit on circular trajectories around the cylinder axis between two concentric cylindrical surfaces, which are composed of specially shaped sheath electrodes, insulated from each other by parabolic gaps, and can harmonically oscillate in the axial direction, independently of their orbiting motion. In the longitudinal direction, the two cylindrical surfaces of the measuring cell are divided by the parabolic separating gaps into different types of double-angled and tetragonal sheath electrode segments. Appropriate voltages at the sheath electrode segments generate a potential distribution between the two concentric cylindrical surfaces which forms a parabolic potential well in the axial direction for orbiting ions. The ion clouds oscillating harmonically in the axial direction in this potential well induce image currents in suitable electrodes, from which the oscillation frequencies can be determined by Fourier analyses.

An elevator system capable of an efficient evacuation using an elevator in case of a fire, and capable of confirming an evacuee remaining status in a case that an evacuation operation using the elevator is discontinued. An evacuation-call response-order setting section sets a priority order of a response to an evacuation special call registered in an evacuation special call registration section, based on fire occurrence information received by a fire situation reception section. A responding floor is selected based on the priority order. The evacuation operation running section controls an operation of the elevator so as to direct a car to the responding floor selected in this manner. In a case that the evacuation operation availability determination section determines that the evacuation operation is not available, the evacuation operation terminating section causes an evacuation special call remaining floor display section to display a remaining evacuation special call registration floor.
