Abstract: A solid state radio frequency switching circuit is provided that exhibits up to 25 db isolation between output ports. The circuit integrates the switching versatility of a pin diode switch with the excellent signal isolation of a quarter wavelength combiner.

Abstract: This invention is a novel plastic bag and method of making it with a handle that extends upward through a folded-back top compartment, and the end of a front of the bag has a pocket with a similar folded-over top edge of the back of the bag. The bags of this invention are made from a continuous sheet, preferably a roll of plastic web that has its opposite side edges folded inwardly along opposite edges of the web to make the folded edges at the front and back sides of the bag. The web is then folded along its longitudinal center region with a gusset that forms the bottom of each bag. The bags have surfaces that are welded together to join areas of the front and of the back where necessary to weld plastic areas together, and certain areas do not weld where the plastic sheet is coated on areas that prevent heat applied to the plastic from fusing together.

Abstract: A method is provided for treating an ethanol mixture containing a substantial amount of water comprising admixing said aqueous ethanol mixture with a hydrocarbon fraction containing a substantial amount of an aliphatic olefin having from 3 to 5 carbon atoms and contacting said admixture with an acidic ion exchange resin catalyst to convert the water in said admixture to an oxygenated organic compound.

Abstract: Vinyl cyclohexene is converted to ethylbenzene and styrene at 170.degree. C.-360.degree. C. in the presence of a hydrogen transfer catalyst typified by IrCl(CO)(Ph.sub.3 P).sub.2.

Abstract: Vinyl cyclohexene is converted to styrene or ethylbenzene at 170.degree. C.-360.degree. C. in the presence of copper chromite catalyst.

Abstract: Aniline may be prepared by reaction of nitrobenzene and vinylcyclohexene at 170.degree. C.-300.degree. C., typically 200.degree. C., in the presence of a homogeneous catalyst typified by IrCl(CO)(Ph.sub.3 P).sub.2.

Abstract: A nitrohydrocarbon, typified by nitrobenzene, is reacted with a hydrocarbon such as 4-vinyl-1-cyclohexene at 70.degree. C.-360.degree. C. and 0-500 psig to give product stream containing aniline, ethylbenzene, and styrene; heterogeneous catalyst contains Group VIII noble metal, Group I B metal and optionally Group VI B metal, typically 0.5% platinum and 5% cuprous oxide on gamma alumina.

Abstract: Vinyl cyclohexene is reacted with nitrobenzene to produce ethylbenzene, aniline, and styrene at 170.degree. C.-360.degree. C. in the presence of a hydrogen transfer catalyst typified by palladium acetylacetonate optionally containing cobalt acetylacetonate or copper oxide.

Abstract: A three-phase electrical transformer utilizes a conductor independent of the transformer windings for sensing zero sequence current upon the occurrence of a ground fault. A current transformer coupled with the independent conductor provides polarization to protective relay devices. One embodiment utilizes the transformer internal tank shield in combination with the current transformer for providing zero sequence current.

Abstract: Surfacing compositions are provided which comprise a mixture of a mineral aggregate, such as particulate slag, asphalt, propoxylated asphalt and, optionally, a silane adhesion promoter.

Abstract: Surfacing compositions are provided which comprise a mixture of mineral aggregate, such as particulate slag, the residuum of a bituminous emulsion and optionally, a silane adhesion promoter. In the emulsion, the emulsifier employed is an alkoxylated asphalt.

Abstract: Vinyl cyclohexene is converted to styrene at 170.degree. C.-360.degree. C. in the presence of copper chromite catalyst.

Abstract: A compact tape cassette player includes a base member defining a channel for slidably receiving a cassette, and a tape transport assembly mounted on a support plate which moves vertically relative to the base plate for engagement and disengagement with a cassette. A lever assembly normally holds the support plate in a raised inoperative position but when the lever assembly is moved against a spring force to an operative position upon insertion of the cassette it allows the support plate to drop into driving engagement with the cassette and latch the lever assembly in the operative position. An eject slide is manually operable to cam the support plate to an inoperative position whereupon the lever assembly is released to eject the cassette.

Abstract: A globe construction for visually determining the time at a geographical area of the earth including a translucent globe, a rotatable hour dial labelled by hours and having perforations through which a stationary dial having minute indicia is viewable through the rotatable dial. The rotatable dial is activated by a timing motor adapted to rotate the hour dial 360.degree. per 24 hour day. The interior of the globe is provided with a light to permit viewing the hour indicia on the hour dial and the indicia on the stationary minute dial.

Abstract: A method of forming a slide fastener having terminal fastener elements reduced in size relative to the remaining fastener elements includes supporting a slide fastener chain to expose the terminal fastener elements, reducing the size of the terminal fastener elements, and fusing a mass of fusible material onto each slide fastener tape to form stop members.

Abstract: An improved rotary-type selector switch for fan speed control or the like including curved terminal members supported upon a base member around a central boss extending therefrom and having a conductive contactor for selectively interconnecting said terminal members when said contactor is pivoted. A cover member is attached to the contactor for pivotal movement together and retains springs which push the contactor against the terminal members and permit movement of the cover toward the contactor. The aforedescribed parts are assembled by a pin fastener with an expandable first end portion which engages the base in snapfitting relation and an enlarged second end portion overlying the cover member. Circumferentially spaced detent means and a projecting ridge formed between the pin fastener and the cover operably engage one another positively to locate the cover and connected contactor in a plurality of annular positions with respect to the base member.
