An LED-based luminaire employs an LED module mounted to a housing. The LED module is advantageously configured to transmit heat generated by the LEDs across and / or through the module and to the housing for dispersal to the environment. LED modules can be configured with conductive or non-conductive cores, and may be configured to evacuate heat from one or both faces of the LED module. Further, multiple heat paths can be defined from components on an LED module to the housing and to the environment.

The present invention 10 discloses a venturi that is installed perpendicularly to the end of the exhaust pipe 12 of a truck or like vehicle 14 thus resulting in the air flow through the venturi being at a 90 degree angle relative to the exhaust gases exiting the exhaust pipe. The present invention 10 seeks to increase the performance and efficiency of an engine of a vehicle 14 by overcoming the backpressure in the engine exhaust system created by the muffler baffles. The present invention 10 may also be installed on automobiles and other motor vehicles 14 having appropriately modified exhaust systems. A front aperture 16 for air intake tapers in width to the back pressure relief port or nozzle 20 being slightly greater than the exhaust port 18 on the bottom portion thereof and then widens to form an air discharge port 22 on the rear portion thereof that is substantially wider and longer than the air intake port 16 thereby creating an air pressure differential wherein the reduced pressure in the back pressure relief port 20 serves to create a vortex to draw exhaust gases from the exhaust pipe 12 toward the discharge port 22.

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.

A horizontally draining artificial turf system comprises an impervious base at proper slope, an impermeable layer or drainage blanket over the base at a corresponding slope for guiding water horizontally, an artificial turf at top of the impermeable layer, and a perforated pipe near the lower edge of the base for receiving water for evacuation. Rainwater over the artificial turf first drains vertically onto the impermeable layer and then flows along the impermeable layer to reach the perforated pipe, without infiltrating into the base. 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.

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.

The present invention is directed to a spout having an evacuation structure for a flexible container. The evacuation structure ensures that the walls of the flexible container do not block the spout of the container during evacuation of fluid from inside the container. The evacuation structure additionally pivots away from the spout during the filling of the container so that the evacuation structure does not impede the fluid entering the container during filling.

A juice press as used in the production of wine for removing liquids from solids, having a horizontally positionable press frame that allows a vertical press mechanism to be rolled to a first position for interference-free loading of a press basket with material to be pressed, and then rolled to a second operating position located over the press basket. The press basket has a liquid channeling plate having an arrangement of holes and channels that creates a perimeter seal along a circumference at the bottom of a loaded press basket. The liquid channeling plate traps naturally occurring sludge along the circumference bottom and allows for efficient evacuation of extracted juice from the bottom of the basket as the press mechanism is operated. In one embodiment, the press frame is configured with a hydraulic press basket lift that raises and holds the press basket after a press operation is completed and allows the press mechanism to be used to eject a disk of compressed solids from the bottom of the raised press basket.
