Title: Open loop mixed refrigerant cycle for ethylene recovery
Inventor: HOWARD LEE JARVIS
IPC: C07C7/04
Filed: 1995-01-30
Granted: 1997-10-14
Abstract: Refrigeration is provided in an ethylene recovery plant by an open-loop mixed refrigeration cycle which utilizes components present in the ethylene-containing feed gas as the mixed refrigerant. Refrigeration is provided by subcooled mixed refrigerant at -175° to -225°F for the demethanizer overhead condenser and for initial cooling and condensation of the ethylene-containing feed gas.  Overall ethylene recoveries of up to 99.9% can be achieved at reduced power consumption compared with conventional ethylene recovery cycles. In addition, significant capital savings can be realized due to the simplification of equipment with the open-loop mixed refrigerant cycle, which can be operated advantageously at pressures between 150 and 400 psia.

Abstract: A high frequency electrical connector having a dielectric block onto which a terminal array of four pairs of electrical conductors are connected, the resulting assembly residing in a jack frame housing configured to removably receive a mating plug. The connector has a planar spring contact region for electrically contacting a corresponding planar contact region of the mating plug, a curved forefront region whereat non-electrical contact cross-overs of the terminal array conductors occurs, and a planar back region where reverse crosstalk is generated. The connector substantially compensates for crosstalk generated at the mating plug and connector contact regions. The configuration of the planar contact region of the mating plug and planar spring contact region of the connector is dictated by industry standards. To generate a sufficient reverse interference to cancel the crosstalk generated in these dimension-regulated parts, an "equivalent distance" of the planar back region sufficient to generate a reverse crosstalk that substantially eliminates the crosstalk generated in the contact regions of the mating plug and connector is provided. This equivalent distance is typically greater than the length of the planar spring contact region since the parallel mating plug conductors and their proximity to the spring contact region contribute to the crosstalk generated by the substantially parallel conductors of the terminal array in the spring contact region. To provide this equivalent distance, the non-contact cross-overs of the conductors are located immediately adjacent to the source of crosstalk without interfering with the industry standard dimensions.

Abstract: An implement hitch is mounted to the forward end of an implement tongue for swivelling about an upright axis. The hitch includes right- and left-hand arm assemblies which each include separate inner and outer arms mounted for swinging about a horizontal transverse axis defined by a connection pin located in respective rear ends of the arms. A first embodiment of the inner and outer arms includes apertured balls universally mounted in forward ends of the arms, with the balls of each adjacent pair of inner and outer arms having a hitch pin extending therethrough which is adapted for being received in the receptacle of the hook of the corresponding side of a quick-coupler carried by the three-point hitch of a tractor. In a second embodiment, radiused apertures are provided in the forward ends of the inner and outer arms in lieu of the apertured balls. In the first, embodiment, the arms pivot vertically relative to each other and the balls swivel within the arms when the quick-coupler tilts relative to the implement swivel hitch whereby the hitch pins also tilt without generating undue loads on the arms. The operation of the second embodiment is similar to that of the first embodiment, however, in this case the radiused apertures in the arms together with the separate movement of the arms permit the pins to tilt without generating undue loads.
