Abstract: A sensor dispensing instrument adapted to handle a sensor pack containing a plurality of sensors and to perform a test using one of the sensors. The sensor dispensing instrument includes an outer housing and a disk drive mechanism contained therein for rotating the sensor pack and ejecting one of the sensors from the sensor pack and through a sensor opening on the housing. The disk drive mechanism of the sensor dispensing instrument is operated by pressing a button which activates a motor. The motor moves a disk drive pusher in a first direction to rotate the sensor pack, and then moves the disk drive pusher in a second direction to eject a sensor from the sensor cavity and through the sensor opening.

Abstract: The present invention relates to an electrochemical cell suitable for a membrane electrolysis process, comprising (i) at least one anode compartment having a metal electrode, (ii) a cathode compartment having a gas diffusion electrode (iii) and an ion exchange membrane arranged between the anode compartment and the cathode compartment. The metal electrode that functions as an anode is capable of being dipped into an electrolyte during use and is provided with one or more orifices for the passage of gas formed during operation. The metal electrode can optionally be angled and/or curved, and the orifices preferably have guide structures that conduct the gas formed to a side of the metal electrode that faces away from the cathode. The present invention also relates to electrodes per se as well as methods for use of electrodes and electrochemical cells.

Abstract: High boiling contaminants such as chloro-aromatic compounds are removed from a gas by compressing the gas containing the contaminant, cooling the compressed gas to reduce the temperature of the gas to at least 20° C. above the outlet temperature of a second cooling stage but above the freezing point of the highest melting compound in the first cooling stage, further cooling the gas in a second cooling stage to at least −20° C., returning cooled gas from the second cooling stage to the first cooling stage, and recovering condensate streams which contain the contaminant compound from the first and second cooling stages. An apparatus suitable for carrying out this process is also disclosed. The process of the present invention is particularly useful for removing chloro-aromatic compounds from anhydrous hydrogen chloride gas.
Abstract: The present invention relates to an improved doctor blade and bedplate apparatus wherein there is a recess in the bedplate from some position upstream of the doctor blade to some position downstream of the doctor blade. This recess or gap in the area of the bedplate under the doctor blade allows one to form an even or uniform coating on the back of a web of material. This is particularly helpful in forming uniform coatings on the back of a greige good which has face fibers of varying lengths. The present invention also relates to an improved process for preparing a relatively uniform coating on the back of a web of material.
Abstract: The present invention relates to a novel process for the preparation of N-methyl-N′-nitroguanidine by reacting nitroguanidine with aqueous methylamine solution buffered by the addition of inorganic or organic acids.
Abstract: Polyisocyanates of the diphenylmethane series are produced by a) reacting aniline and formaldehyde in the presence of an acidic catalyst to produce a polyamine, b) neutralizing the reaction mixture from step a) with a base at a temperature of more than 110° C. or neutralizing the reaction mixture from step a) with a base and heating the neutralized mixture to a temperature of more than 110° C., and c) phosgenating the polyamine from step b) to convert it to the corresponding polyisocyanate.

Abstract: A process for producing polymer pellets is disclosed. The process that is particular suitable for making polycarbonate pellets entails extruding a polymer melt, cooling the extrudate by contacting it with a cooling fluid and pelletizing the solidified polymer. The process is characterized in that the cooling fluid has a solids particle content of at most 10 ppm.
Abstract: A reference electrode assembly having a constrained-diffusion liquid junction between a liquid junction solution and a sample solution having separate flow paths, said assembly comprising a flow cell having attached thereto a constraint comprising a region of porous material permeable to water and salts; a remote reservoir for holding said liquid junction solution; a means for moving said liquid junction solution from said reservoir to said constraint; and a reference contact region is provided. This unique configuration provides a reference electrode device of the constrained-diffusion liquid junction type useful in pH and/or ion-selective electrode (ISE) potentiometric sensors and is particularly suitable for use in a mini-integrated electrochemical analyzer.
