Abstract: ABSTRACT A laminated thermoplastic packaging film which is integrally reinforced by means of integral ribs which form a part of the film structure. The ribs on each side are parallel to each other and are oblique to the longitudinal and traverse axes of the film. The ribs on opposite sides of the laminate run in intersecting directions to form a network-like configuration. The ribs may be formed with a tubular extrusion die which has been provided with small notches with rounded corners around the periphery of the die orifice. As the film is being extruded, the notched portion of the die is rotated so that the rib reinforced extruded product is characterized by having ribs, tracking in a helical path, around the extruded film tube. The extruded thermoplastic tubing with the helical ribs may then be flattened while still in a heat-softened condition, by a pair of rollers or other means, to form a two-layer. The resultant laminate is characterized by having a diamond-like network of intersecting reinforcing ribs and may be used in the fabrication of articles such as bags, packaging material and the like.

Abstract: A PROCESS FOR PRODUCING HYDROCARBONS             AND THE CATALYST USED THEREIN                 ABSTRACT OF THE DISCLOSURE        This invention relates to an improvement in a Fischer-Tropsch catalytic process of synthesizing a hydrocarbon stream and to the catalyst used therein.  The process may be used for synthesizing a high percentage of C2 - C4 hydrocarbons or for synthesizing a high percentage of liquid hydrocarbons in the gasoline and diesel fuel range while obtaining excellent con-version percentages by varying the process conditions.  A high percentage of C2-C4 hydrocarbons is obtained by conducting said reaction at a temperature of from about 275° to 375°C, a press-ure of from about 75 to 350 psi, a space velocity of about 50 to 400 hours -1 in the presence of the novel catalyst.  A high per-centage of liquid hydrocarbons in the gasoline and diesel fuel range is obtained by conducting said reaction at a temperature of from 225 to 275°C, a pressure of from about 200 to 350 psig, a space velocity of from about 50 to 300 hours -1 in the presence of the novel catalyst.  The novel catalyst comprises from about 100 to 1 parts iron per part copper, the catalyst being carried on a support selected from the group consisting of a zeolite, silica-alumina and mixtures thereof.

Abstract: ABSTRACT An electronic watthour meter for connection in a two-wire power distribution circuit comprises a shunt connected in one of the wires and an electronic circuit comprising a transconductance multiplier, a V to F converter and a reversible counter.  The DC power supply of the electronic circuit is referred to the wire containing the shunt, which wire is always live, so that the electronic circuit "floats" electrically on this live wire. The first input of the multiplier can therefore be directly connected across the shunt, and the second input is connected via a high value resistance to the other wire so as to receive an input current representative of the voltage between the wires.  To eliminate the effects of drift in the multiplier, the polarity of the input current to the multiplier and the direction of counting of the counter are periodically and simultaneously reversed by a square wave signal of 1:1 mark space ratio.  The electronic circuit is implemented using LSI techniques.

Abstract: ABSTRACT OF THE DISCLOSURE           The oxidation-corrosion resistance of plasma sprayed MCrAlY overlay coatings is improved.  The coating method involves plasma spraying the MCrAlY coating alloy onto a superalloy substrate, applying a chromium or aluminum envelope over the outer surface of the coating or mechanically working the outer surface to seal the sur-face against penetration by the high pressure isostatic atmosphere to be subsequently applied and then hot iso-statically pressing the coated substrate to close the coating defects and diffuse at least a portion of the envelope, if present, into the overlay coating.  The invention thus can provide an MCrAlY coating not only substantially free of pores, voids and the like defects but also having at least an outer zone enriched in chromium, aluminum or like metals.

The separated, heavier sand particles and the lighter coating materials are deflected downwardly by the target and a secondary fluid flow is provided to move outwardly of the lift tube for intercepting the downward curtain of particulate matter and coating materials and carrying away the lighter coating materials while permitting the heavier sand grains to con-tinue to fall downwardly.  An outlet fluid exhaust valve is - i -provided for adjustably controlling the outflow of air and coating materials that are removed from the sand grains. A plurality of scrubbing units as described are arranged in series and a novel baffle system is provided to deflect a portion of the material from one unit into the next unit and recycle the remaining portion.
