Abstract: A leak detection system capable of automatically detecting a leak in a pressurized piping system. A pressure decay test is utilized to test for leaks in the piping system. Disruption to users of the piping system is reduced by only performing the pressure decay test when there is no user demand on the piping system. Thus, a leakage test is performed by first determining whether there is user demand on the piping system and proceeding with a pressure decay test only if there is no user demand present. If user demand is initiated during the performance of a pressure decay test, the system detects the user demand and halts the pressure decay test until the user demand stops.

Abstract: Improved methods for producing titanium dioxide slurries. The output from a micronizer is passed through a condenser to condense the steam and form an aqueous slurry of titanium dioxide, which can in most cases then be further concentrated as desired or which can be sold or used without further concentration, instead of passing the micronizer output to apparatus for separating the TiO2 from the steam, as is currently practiced in the art. The resultant slurry from the condenser is in a further refinement preferably sent to an agitated storage tank together with dispersant and anti-settling compounds to aid in preventing settling of the titanium dioxide solids out of the slurry. To help facilitate condensation of the steam/pigment mixture sent to the condenser, a portion of the condensed slurry is in yet a further refinement pumped from the slurry storage tank to a heat exchanger. The output from the heat exchanger is then fed to the condenser to facilitate the condensing of the steam in the condenser.

Abstract: According to the present invention, there is a methylcellulose having a methoxy substitution of about 21 to about 42 percent based upon the weight of the cellulose ether and elastic modulus (EM) of EM≧181.3×(v0.2711) wherein “v” is viscosity of a two percent solution of the cellulose ether at 20° C. Further described is a process for making the cellulose ether, a food composition containing it, and a pharmaceutical capsule containing it.

Abstract: Methods and devices for producing plasmas of more uniform density and greater height than plasmas generated by previously known magnetron-type plasma-generating devices. The present invention utilizes electrodes containing multiple magnets positioned such that like magnetic poles of the magnets are all facing in substantially the same direction.

Abstract: A deformable label comprising a printable film facestock having at least one layer containing incompatible polymers. The printable film facestock exhibits significantly reduced die-face buildup during extrusion of the printable film facestock when compared to the die-face buildup exhibited by film facestock of the prior art. The present invention provides for monolayer film facestock containing incompatible polymers and colorants. The present invention also allows printable film facestock to be produced in a more cost-effective manner.

Abstract: A multilayer film useful for making plastic adhesive labels for glass substrates such as glass bottles. The multilayer films contain a base layer, an adhesive layer, and optionally an intermediate layer to improve interlayer bonding between the base layer and the adhesive layer. The adhesive layer comprises a terpolymer of ethylene, 3-10 weight percent of an ethylenically unsaturated carboxylic acid (e.g. acrylic acid or methyacrylic acid), and 3-25 weight percent of an unsaturated ester (e.g., methyl, ethyl, or n-butyl acrylate or methacrylate). The base layer preferably comprises oriented polypropylene or oriented polyester, but may also comprise high density polyethylene or PETG. The multilayer film can be utilized in conventional graphics printing operations and do not require the use of a separate release liner.
