Title: Attenuating fluid manifold for meltblowing die
Inventor: ERICKSON STANLEY C
IPC: D04H3/16
Filed: 2003-04-21
Abstract: Melt blown nonwoven webs are formed by supplying attenuating fluid to a meltblowing die (12) through an attenuating fluid distribution (10a-b) passa ge whose distribution characteristics can be changed while the die (12) and manifold (22) are assembled. By adjusting the distribution characteristics o f the passage, the mass flow rate of attenuating fluid to channels in the meltblowing die (12) and the temperature of the attenuating fluid at the die outlets (18) can be made more uniform.

Abstract: The invention relates to a vector for the production of transplastomic angiosperm plants. More specifically, the invention relates to a DNA vector which enables the stable insertion and expression of heterologous genes in t he genomes of cell plastids from any angiosperm plant. In the aforementioned vector, the genes to be introduced can be inserted in multiple cloning sites which are located in an artificial intergenic region which is obtained by combining the rbcL and atpB operons from plants of different groups (dicotyledons or monocotyledons). The expression cassette is integrated into the genome by means of recombination between the rbcL and atpB border sequences of the vector with the corresponding homologous regions of the plastid genome. More than one gene of interest can be expressed from the rbc L promoter adjacent to the border region which codes for the atpB gene.</SDOAB >

Abstract: A cold arc discharge is used to decompose natural gas or methane into its gaseous constituents and carbon in the form of solid particles. The gaseous constituents obtained are mainly hydrogen and acetylene and they are produced in admixture with unreacted natural gas or methane. The cold arc discharge is generated by a pulsating high voltage discharge imparted through a capacitor to a high voltage electrode or a plurality of high voltage electrodes or through a high voltage electrode to a plurality of capacitor-connected electrodes placed in a reaction zone. The apparatus for performing this process may have a tubular reactor with a cylindrical ground electrode in the middle and a cylindrical outer wall through which the high voltage electrode or electrodes extend into the reaction zone. The apparatus may also have a cylindrical shaft in the middle made of dielectric material in which a plurality of electrodes are embedded, this shaft being surrounded by a high voltage tubular electrode. Natural gas or methane is passed through the reaction zone where it is subjected to the cold arc discharge or discharges and the resulting products flow out of the reactor and solid carbon particles are separated from the remaining gases that are then analysed.

Abstract: The invention is an inflatable mailer having a liner that can be inflated at the point of use. The liner includes a series of inflatable chambers that are in fluid communication with a common channel. A controlled volume of gas is disposed in the liner.
