Abstract: Disclosed is a transponder of a radio frequency identification system. Connected to a controller is a memory storing r-pages of k-bits of data. A first page includes an ID code relating to an integrated chip forming part of the transponder. The controller is configured, after the transponder has been interrogated by a reader, automatically and on a transponder talk only basis, to transmit transponder ID data including a concatenation of pages. Each page is led by a respective m-bit header. The header includes: (a) a first part having a random number, (b) a second part having for the first page in the ID data, a total number of pages in the ID data and for any subsequent page, a page number of the page in the memory and; (c) a third part having a sequential number for the page in the ID data.

Abstract: Disclosed is a method of improving the release of paper webs from the surface of press rolls or other paper making or converting equipment by applying to such a surface non-aqueous, non-curing hydrocarbon polymer compositions. The non-curing hydrocarbon polymers have the formula (CH3)3C—[—C(R1)(R2)—C(R3)(R4)—]n—C(R5)═C(CH3)2 (I) wherein R1 through R5 are hydrogen or —CH3, with at least one of R1 through R4 being —CH3, and n is such that the number average molecular weight of such hydrocarbon polymers is from 50 to 3000. They may be hydrogenated. Preferred non-curing hydrocarbon polymers are polybutenes of the formula (CH3)3C—[—CH2—C(CH3)2—]n—CH═C(CH3)2 (II). Preferred compositions comprise at least one such hydrocarbon polymer component having a number average molecular weight from 400 to 700 and a second such component having a number average molecular weight of 100 to 400.

Abstract: Method of inhibiting the deposit of sticky material on a papermill felt used in processing pulp slurry into sheets, comprising applying to the papermill felt at least one cationic polymer and at least one nonionic surfactant having an HLB of about 11 to 14.

Abstract: An automated biomonitoring system for monitoring water quality includes an exposure chamber for housing an aquatic organism having ventilatory behavior and body movement sensitive to water quality. Electrodes capture electrical signals produced by the organism during its ventilatory behavior and body movement, and a controller responsive to signals from the electrodes determines one or more ventilatory parameters based on the signals. The ventilatory parameters are compared with corresponding thresholds to determine when the water to which the organism is exposed has caused physiological stress to the organism. The signals captured by the electrodes may be corrected for variations in water conductivity so that the signals processed by the controlled are not influenced by conductivity.

Abstract: A composition for controlling deposition having a high flash point and being substantially free of volatile organic compounds is disclosed, the composition being a stable solution containing a dialkylsulfosuccinate, an ethylene oxide/propylene oxide block copolymer and a mineral acid.

Abstract: A method for controlling foam in the papermaking operation comprising a polyether surfactant and polyethoxylated sorbitol hexaoleate.

Abstract: A composition and method for controlling foam in the coating solution of a papermaking operation consisting of a polyether surfactant and polyethoxylated sorbitol hexaoleate.

Abstract: A composition to control foam in aqueous systems such as those found in papermaking operations comprising a polybutene and at least one surfactant having a melting or pour point below 20.degree. C. The surfactants include polyethylene glycol esters, sorbitan ester, polyoxyalkylene ester, oleic diethanolamide and block copolymers of ethylene oxide and propylene oxide. Due to their low melting point, these surfactants may be blended with the polybutene at room temperature resulting in a foam control composition that is translucent, resistant to deposition and highly effective.
