Abstract: A novel metallized film capacitor is contemplated. The capacitor includes a first film and a second film. Each of the first film and second film have a metallized layer added. Each of the metallized layers includes alternating metallized sections and margin sections. The outermost sections on one film are metallized sections, while the outermost sections on the other film are margin sections. This pattern and proper sizing of the sections creates overlap regions where a metallized section from one film overlaps a metallized section from the other film. These overlap regions create sub-capacitors that give the capacitor low inductance while allowing for high current and high voltage.

Abstract: An electromagnetic antenna for Measurement-While-Drilling (MWD) applications is disclosed. The antenna can include several array elements that can act alone or together in various measurement modes. The antenna elements can be disposed in tool body recesses to be protected from damage. The antenna elements can include a ferrite plate crossed or looped by independent current carrying conductors in two or more directions forming a bi-directional or crossed magnetic dipole. Although disclosed as a MWD system conveyed by a drill string, basic concepts of the system are applicable to other types of borehole conveyance.

Abstract: An apparatus for dispensing sheets, including cash, which comprises first conveying elements for dispensing sheets along a feed path to a stacking position; first detection device for detecting unsuitable sheets; and diverting elements for diverting detected unsuitable sheets along a reject path to a dump. Stacking elements are positioned downstream of the diverting elements for stacking sheets at the stacking position. Second conveying elements are provided for selectively delivering the stacked sheets to a dispense outlet or along a reject path to the dump.

Abstract: A solution of a di-alkyl carbonate, e.g. dimethyl carbonate, in the corresponding alcohol, e.g. methanol, is concentrated by contacting the solution with a hydrophobic zeolite e.g. silicalite. The di-alkyl carbonate is absorbed preferentially. Where the solution also contains water, e.g. as in the case of the products from certain di-alkyl carbonate synthesis reactions, the water can be removed using a hydrophilic zeolite prior to recycle of the alcohol.

Abstract: A feedstock comprising a hydrocarbon containing 2 or more carbon atoms in the molecule and/or a hydrocarbon derivative containing hydrogen-carbon links is converted to olefins over the zeolite NU-3. When in particular the feedstock is methanol or dimethyl ether olefins are formed with high selectivity against formation of aromatics.

Abstract: A catalyst for hydrocarbon conversion contains a silica-containing material having a plate or sheet morphology, for example "FU-1" and a material having catalytic activity for hydrocarbon conversion, for example rare-earth exchanged zeolite Y. The catalyst is especially suitable for cracking heavy fractions to naphtha-type products, apparently because the plate or sheet material provides channels by which large molecules can gain access to active centers in the catalyst.

Abstract: Olefins are produced by reacting a feedstock containing a hydrocarbon containing 2 or more carbon atoms in the molecule and/or a hydrocarbon derivative containing hydrogen-carbon links over a catalyst comprising "FU-1," which is a zeolite-like silica-containing material characterized inter alia by chemical composition and X-ray diffraction pattern. The feedstock is preferably methanol or dimethyl ether. The predominant olefin product can be controlled according to the reaction conditions used. Conversion to aromatics is very low.
