Recreational bone conduction audio device, system
Patent 8,111,860
A waterproof recreational audio device and method that transmits sound via transcutaneous bone conduction provides high fidelity musical signals to a user. The device can be worn on the head of a user and integrated into various types of headgear. The device is tunable for sound quality and comfort by adjusting and moving the sound transmitting transducers around the head of the user. The present invention uses commercially available transducers to produce sounds in the low, mid and high frequency ranges. A sound source for the musical signal can also be provided as part of the waterproof recreational audio device. Controls enable the user to select volume levels for the high, mid and low frequency ranges, while a volume limiter restricts the mid range to a preset maximum volume level to allow external ambient sounds to be heard via the ear canal and protects the hearing of the user.

Adsorbents for smoking articles comprising a non-volatile organic compound applied using a supercritical fluid
Patent 8,114,475
A surface-modified adsorbent and a process for making a surface-modified adsorbent are provided. The process involves providing an adsorbent and a non-volatile organic compound to a vessel, adjusting the temperature and/or pressure to provide supercritical conditions for a supercritical fluid, and introducing the supercritical fluid into the vessel. The supercritical fluid dissolves the non-volatile organic compound, and impregnates the adsorbent with the non-volatile organic compound. The surface-modified adsorbent can be used, for example, in cut filler compositions, cigarette filters, and smoking articles. Methods for making cigarette filters, cigarettes and for smoking a cigarette comprising the surface-modified adsorbent are also provided. The surface-modified adsorbents can be used to remove one or more selected components from mainstream smoke, without removing other components, such as those that contribute to flavor.

Vertical filter filling machine and process
Patent 8,114,002
Process and apparatus for the mass production of compound cigarette filters function to deposit granular filter material into the open ends of vertically oriented filter tubes. Predetermined amounts of diverse granular material are withdrawn by suction from sources of such material, and these amounts are deposited into the tubes. Solid filter segments seal the granular material within the tube. After one half of each filter tube is filled with granular material and sealed, the tube is inverted and the opposite end is filled in substantially the same manner. When cut in half each filter tube produces two cigarette filters.

Synthesis and incorporation of high-temperature ammonia-release agents in lit-end cigarettes
Patent 8,113,216
A tobacco smoking mixture and/or a cigarette wrapper with high-temperature ammonia-release agents therein are provided, wherein the high-temperature ammonia-release agents are present in an amount effective to reduce the cytotoxicity of gas phase or particulate matter formed during smoking of the cigarette. The high-temperature ammonia-release agents are capable of reducing the cytotoxicity of gas phase or particulate matter by evolving ammonia at temperatures greater than about 200.degree. C., wherein the ammonia can interact with the particulate matter. Additionally, the high-temperature ammonia-release agents can be formed by heating an aqueous mixture of an iron precursor compound, an ammonia source compound and an acid.

Smoking article filter having liquid additive containing tubes therein
Patent 8,113,215
Provided are filters including at least one impervious additive containing tube. A barrier, such as a liquid barrier, seals each end of the tube so as to contain additives, such as a liquid additive, within the additive containing tube. The one or more additive containing tubes are inserted into filters for smoking articles. Drawing action during a puff causes breach of the barrier and release of the additive into the surrounding filter material.

Treatment using dantrolene
Patent 8,110,225
Provided are low-volume, safe for injection formulations of dantrolene yielding significant advantages over the currently approved and marketed dantrolene for malignant hyperthermia (MH) threatening anesthetic crisis. Once dantrolene can be made immediately available to patients triggered of MH, the anesthesiologist will be able to focus exclusively on the management of the patient’s physiologic status in this complex and evolving crisis, not on the laborious and time consuming reconstitution process of the rescue agent. The low volume, safe for injection formulations of dantrolene have significant advantages over currently used approaches to the prevention and treatment of pumphead, and other neurological, cognitive and motor dysfunction incident to iatrogenically or trauma induced situations of altered blood flow, including those incurred during surgical procedures involving CPB or related procedures, as well as those incurred during non-normothermic episodes caused iatrogenically or by disease.

Patent 8,109,750
Feb. 7, 2012
A process for the production of virtually full density polyolefin suitable for further processing by drawing to form a high tenacity, highly oriented polyolefin sheet comprising: a) feeding a metered amount of polyolefin powder into the nip between two heated calender rolls initially set at a gap smaller than the size of the smallest polyolefin powder particle and at a temperature above the melting point of the powder; b) rolling the powder through the nip under these conditions until a coherent sheet of polyolefin is produced: and c) once a coherent sheet of polyolefin exits the nip lowering the temperature in the nip to a temperature below the melting point of the polyolefin powder and increasing the gap to a desired level above the thickness of the largest powder particle. Apparatus for the performance of such a process is also described.

Bearing assembly having a dual stage seal
Patent 8,109,674
A bearing assembly is presented having a novel lubricant sealing design that, in one embodiment, combines the sealing advantages of both a labyrinth-like seal in combination with a contact seal. The improved seal includes a non-rotating seal case working in closely spaced cooperation with a rotor to form a channel. The rotor is attached and turns with the shaft, inducing flow in the channel. Lubricant leakage is impeded by the tortuous fluid path formed by the convoluted channel of the labyrinth-like seal and the fluid shear forces developed by the turning shaft. Any lubricant leakage is further impeded by a resilient seal contacting the surface of the rotor and constricting the channel.

Dihydroxy enol compounds used in chemical mechanical polishing compositions having metal ion oxidizers
Patent 8,114,775
A chemical mechanical polishing composition contains 1) water, 2) optionally an abrasive material, 3) an oxidizer, preferably a per-type oxidizer, 4) a small amount of soluble metal-ion oxidizer/polishing accelerator, a metal-ion polishing accelerator bound to particles such as to abrasive particles, or both; and 5) at least one of the group selected from a) a small amount of a chelator, b) a small amount of a dihydroxy enolic compound, and c) a small amount of an organic accelerator. Ascorbic acid in an amount less than 800 ppm, preferably between about 100 ppm and 500 ppm, is the preferred dihydroxy enolic compound. The polishing compositions and processes are useful for substantially all metals and metallic compounds found in integrated circuits, but is particularly useful for tungsten. The present invention also pertains to surface-modified colloidal abrasive polishing compositions and associated methods of using these compositions, particularly for chemical mechanical planarization, wherein the slurry comprises low levels of chelating free radical quenchers, non-chelating free radical quenchers, or both.
