Title: Sidestream smoke reducing cigarette paper with improved physicals and improved sidestream odor/aroma
Inventor: BROWN J PAGE
IPC: A24D1/02
Filed: 1990-08-30
Granted: 2000-02-01
Abstract: Sheet material containing sodium carboxymethyl cellulose especially useful in forming wrappers for smokeable articles such as cigarettes that results in reduced sidestream smoke.      The sheet is preferably formed by incorporating as a filler in a cellulosic web an amount of high superficial surface area filler in the range generally of from about 5 to 50 percent by weight in the finished sheet. The cellulosic material may be flax fiber or other natural cellulosic fibers conventionally used for such wrappers. Additional fillers may be used up to a total of about 50 percent, and, preferably, a burn modifier, carboxylic acid salt, preferably a nonhydroxy acid salt such as succinic acid salt is included in an amount of 4 to 15 percent by weight. The sheet can be formed by any conventional papermaking method. When such papers are used as cigarette wrappers, they effect a reduction of the total particulate matter in sidestream smoke of up to about 75 percent with improved taste and odor and without serious deterioration of other desirable properties. In addition, the sheet of the invention provides normal ash appearance in a smoking article.

IPC: C23C16/40
Filed: 1991-06-06
Granted: 2002-06-04
Abstract: A method for coating finely divided material with titania is disclosed. The method involves the fluidization of the finely divided material in an inert carrier gas containing vaporized titanium isopropoxide.      The isothermal fluidized bed is kept at a temperature equal to or below approximately 300°C. The vaporized titanium isopropoxide reacts to form a coating of titania on the surfaces of the particles within the fluidized bed.      The greatest coating efficiency occurs when the fluidized bed is kept at approximately 300°C for approximately the first 10 minutes of the reaction and thereafter at approximated 250°C. The titania coating process is particularly useful for electroluminescent phosphors such as copper doped zinc sulfide phosphor. The titania coated electroluminescent phosphors are relatively insensitive to moisture. Lamps made from the coated electroluminescent phosphor are also relatively insensitive to moisture.

Title: Feedback system for load bearing surface
Inventor: GROSS CLIFFORD M
IPC: B60N2/90
Filed: 1991-11-26
Granted: 2005-02-22
Abstract: An electronic system for adjusting a load bearing surface such as a chair or bed to provide a desired level of comfort comprises an array of pressure sensors located within the load bearing surface. The pressure sensors generate data indicating the actual distribution of pressure exerted by a user on the load bearing surface. An electronic processor processes the data generated by the array of pressure senors. The processor compares the fraction of total load exerted on each of a plurality of regions of the load bearing surface with a desired range for each region. If the fraction of total load for any region is not within the desired range, a servo-mechanism is activated to change the shape of the load bearing surface so that the fraction of total load on each region is within the desired range, so as to provide a desired level of comfort to the user.

Inventor: PALMER DAVID
IPC: F24F11/75
Filed: 1992-03-13
Granted: 2002-12-10
Abstract: To control the flow of air from a process chamber, such as a clean roam, to an exhaust, a movably mounted piston (5) that is attached to a movably mounted gate (96, 961) is disposed adjacent to the flow, so that the flow passes immediately over the frontal face (52) of the piston.

The gate is mounted so as to variably impede the flow downstream of the frontal face of the piston. A restoring force, preferably the weight of the piston and the gate, tends to move the piston so as to lessen the gate's impedance on the flow.

Abstract: A hologram surface to express a phase distribution, a visual field in which a solid image can be seen; and a stereoscopic display limit are set in a virtual space.  A target to be stereoscopically displayed is subsequently expressed in the virtual space by a set of micro polygons.

In the calculation of a phase distribution, sampling points are set onto the extracted line segment, a 1-dimensional hologram phase distribution on the hologram surface is calculated every sampling points, and the calculated 1-dimensional hologram phase distributions are added every same slice plane.
