Title: Improved drive socket design for hold and drive fastener
Inventor: GOSS DAVID
IPC: B25B31/00
Filed: 2008-05-01
Granted: 2012-09-11
Abstract: A drive tool (100) that includes a drive socket (102). The drive socket (100) includes alternating flutes (104) and lobes (106) and has a conical section (108). The lobes (106), rather than being tapered in the conical section (108) of the socket (102), are each uniform in width as they progress to an end (110) of the socket (102). The fact that the lobes (106) are uniform in width in the conical section (108) of the drive socket (102) provides for better engagement with the flutes (38) of a conical section (28) of a fastener (22).

Title: Apparatus and method for facilitating the replacement of an implanted catheter
Inventor: PORTER CHRISTOPHER H
IPC: A61M1/00
Filed: 2007-01-06
Granted: 2014-11-18
Abstract: A medical apparatus and method of use for implanting a percutaneous catheter in a patient's body which catheter can be easily positioned, repositioned, and replaced. The apparatus includes an elongate sleeve comprising a wall surrounding an interior elongate passageway. The passageway extends from a sleeve proximal end to a sleeve distal end. The sleeve is intended to be percutaneously implanted through an incision in the patient's skin so that the sleeve distal end resides subcutaneously. The sleeve outer peripheral surface carries a layer of porous material intended to be placed just under the patient's outer skin layer in contact with the dermis to promote tissue ingrowth for anchoring the sleeve and forming an infection resistant barrier. The sleeve passageway is dimensioned to snugly accommodate the outer surface of catheter while permitting the catheter to slide relative to the sleeve. A sealing device is mounted around the catheter adjacent to the sleeve proximal end to prevent deleterious material from migrating into the patient's body along the catheter outer surface.

Abstract: In apparatus and method for waste treatment by pyrolysis, treated waste is flushed through a grid (18) to trap recyclable material in the pyrolysis chamber (24). Pyrolysis is carried out at a temperature of from 400-700oC and off-gases are dissolved in a solution in scrubber (13) for disposal in a water course. Water is introduced into the chamber as superheated steam via pipes (5) so as both to flush away treated material and clean the chamber. Recyclable waste is separated from non-recyclable by treating non-recyclable waste by pyrolysis, and flushing treated non-recyclable waste away through liquid exhaust (8). Apparatus is made as a modular, free-standing unit and comprises plugs for connection to an electricity supply, to a water supply, and to a sewerage system (16) and has a chamber with a volume in the range 0.01-0.5m3.

Title: Methods and apparatus for processing audio signals
Inventor: ABOLFATHI AMIR
IPC: A61F11/04
Filed: 2007-05-29
Granted: 2011-11-01
Abstract: Various methods and apparatus for processing audio signals are disclosed herein. The assembly may be attached, adhered, or otherwise embedded into or upon a removable oral appliance to form a hearing aid assembly. Such an oral appliance may be a custom-made device which can enhance and/or optimize received audio signals for vibrational conduction to the user. Received audio signals may be processed to cancel acoustic echo such that undesired sounds received by one or more intra-buccal and/or extra-buccal microphones are eliminated or mitigated. Additionally, a multiband actuation system may be used where two or more transducers each deliver sounds within certain frequencies. Also, the assembly may also utilize the sensation of directionality via the conducted vibrations to emulate directional perception of audio signals received by the user. Another feature may include the ability to vibrationally conduct ancillary audio signals to the user along with primary audio signals.

Abstract: The subject invention relates to a novel gene referred to herein as DSM-2. This gene was identified in Sterptomyces coelicolor A3. The DSM-2 protein is distantly related to PAT and BAR. The subject invention also provides plant-optimized genes encoding DSM-2 proteins, DSM-2 can be used as a transgenic trait to impart tolerance in plants and plant cells to the herbicides glufosinate and bialaphos. One preferred use of the subject genes are as selectable markers. The use of this gene as a selectable marker in a bacterial system can increase efficiency for plant transformations. Use of DSM-2 as the sole selection marker eliminates the need for an additional medicinal antibiotic marker (such as ampicillin resistance) during cloning. Various other uses are also possible according to the subject invention.

Abstract: A paperboard carton doubles as a shipping container for articles such as beverage cans and a cooler for containing ice to cool the articles when the carton is opened. The top portion of the carton is breached by removing an opening strip defined by zipper rules. Once breached, the tops and side panels of the carton are opened up to form an upwardly open chimney or skirt into which ice can be placed to cool the contents of the carton. Gussets formed in the lower corners of the cartons insure that water from melting ice does not leak prematurely from the carton.
