Title: Wireless conference call telephone
Inventor: BURNETT GREGORY C
IPC: H04M1/72412
Filed: 2011-07-15
Abstract: A wireless conference call telephone system uses body-worn wired or wireless audio endpoints comprising microphones or microphone arrays and, optionally, speakers. These audio-endpoints, which include headsets, pendants, and clip-on microphones to name a few, are used to capture the user's voice and the resulting data may be used to remove echo and environmental acoustic noise. Each audio-endpoint transmits its audio to the telephony gateway, where noise and echo suppression can take place if not already performed on the audio-endpoint, and where each audio-endpoint's output can be labeled, integrated with the output of other audio-endpoints, and transmitted over one or more telephony channels of a telephone network. The noise and echo suppression can also be done on the audio-endpoint. The labeling of each user's output can be used by the outside caller's phone to spatially locate each user in space, increasing intelligibility.

Title: Closure for a drill hole
Inventor: SPLITTSTOESSER WULF
IPC: E21B33/12
Filed: 2011-07-07
Abstract: The object of the invention is to provide a device for closing a drill hole (102), which can be universally used and is capable of closing the drill hole (102) even in the case of damages which are located below a blowout preventer that may be present. The invention is based on the idea of introducing a closure into the drill hole (102) in order to seal the same in the event of damage and rising fluid. To this end, the closure comprises at least one skirt (106) or one capsule (401). A non-positive and/or positive connection to the wall (104) of the drill hole (102) is achieved by opening the skirt (106) or expanding the capsule, so that the drill hole (102) is closed.

Abstract: The present invention is directed to a corrosion resistance evaluator suitable for corrosion testing coated metals substrates, such as auto bodies at an accelerated rate. A corrosion resistance evaluator provided with a chamber containing electrolyte to which anode and cathode coated with protective coating being tested are exposed. These coatings are provided with predetermined and standardized defects, such as micro-holes to accelerate the corrosion of the underlying metal substrate in a predictable and repeatable manner. The coated cathode/anode pair is subject to a start-up period followed by series preset DC voltages modulated in a stepwise manner for preset durations that are interspaced with recovery periods. The impedance date collected is then used to arrive at the corrosion performance resistance of the coating applied over the cathode/anode pair. The foregoing evaluator substantially reduces the time required to test corrosion from several days (40 plus days) to few days (about two days).
