20110273845 | HIGH POWER BAND PASS RF FILTER HAVING A GAS TUBE FOR SURGE SUPPRESSION - A high power band pass RF filtering device having a housing for containing a printed circuit board with filtering components for achieving strong attenuation of out-of-band signals. An input port and an output port on the housing electrically connect to a respective input node and output node on the printed circuit board. Surge protection elements are connected at the input port and at the output port for dissipating surge conditions present at the input port or the output port to the housing before the surge travels through the printed circuit board. A non-surge signal present on the input port can travel through the filtering components on the printed circuit board towards the output port. An oil or other fluid is disposed and completely contained within the housing and contacts the printed circuit board for cooling the printed circuit board or the filtering components. | 11-10-2011 |
20120068789 | HIGH POWER BAND PASS RF FILTER HAVING A GAS TUBE FOR SURGE SUPPRESSION - A high power band pass RF filtering device having a housing defining an interior chamber and having one or more walls for substantially dividing the interior chamber into one or more sections. A circuit with filtering components for achieving strong attenuation of out-of-band signals is disposed within the interior chamber, certain components of the circuit being separated from one another by the walls. Ports on the housing electrically connect to a respective input node and output node of the circuit and also connect to surge protection elements for dissipating surge conditions present at the ports. A non-surge signal can travel between the ports and through the filtering components. An oil or other fluid is disposed and completely contained within the housing and contacts the circuit components for cooling the circuit components. | 03-22-2012 |
20120154167 | SURGE PROTECTION DEVICES THAT FAIL AS AN OPEN CIRCUIT - A surge protection apparatus or method for opening a surge path upon failure of a surge protection element as a short. The surge protection device may include a switch controlled by a solenoid or other switch controlling component that changes a position of the switch if the surge protection element fails as a conductive element. A first position of the switch is configured to allow transmittal of a signal from a signal connection, through the surge protection element, and to a ground connection. A second position of the switch is configured to prevent transmittal of a signal from the signal connection, through the surge protection element, and to the ground connection. A delay may be added between the changing of the switch position after the surge protection element fails as a conductor. Visual or other notifiers may indicate when the switch is in the second position. | 06-21-2012 |

20150145169 | Fabricating an Object With a Removable Raft by Additive Manufacturing - An additive-manufacturing removable raft. Layers of material are sequentially deposited on a build platform. Portions of the perimeters of the layers are defined as bevel portions, the bevel portion of each layer after the first overhanging the bevel portion of the preceding layer to form an edge surface of the raft at an acute angle with respect to the build platform. | 05-28-2015 |
