Title: Method for restoring the functionality of equipment subjected to heavy corrosion in a plant for the production of urea
Inventor: MIOLA CESARE
IPC: B01J19/00
Filed: 1995-09-08
Granted: 2006-01-24
Abstract: The present invention relates to a method for repairing and restoring the functionality of equipment subjected to internal corrosion during its operation at high or medium pressure in a plant for the synthesis of urea. This method comprises: 1) the cleaning of the corroded area; 2) the formation, in the cleaned area, of suitable supporting and/or holding surfaces for the placement of new metallic lining; 3) the formation of new, anticorrosive, sealed off lining, obtained by positioning and welding flat elements and metallic plates suitably shaped and placed next to each other to become adapted to the internal profile of the equipment so that the spaces and interstices below this new lining, all communicate with at least one weep-hole present in the pressure-resistant body. The entire repair is carried out through the manhole of the equipment and enables the restoring of its functionality for times similar to the normal duration of corresponding newly-constructed equipment.

Abstract: A dock leveler includes a pivotally mounted ramp and a lip member pivotally mounted to the distal end of the ramp and moveable between an extended position and a depending position for forming a path between a loading dock and a loadbed of a vehicle. A motor operated linear power screw type actuator is connected to the ramp for moving the ramp to an elevated position and includes an extensible tube member which is engageable with a second tube in telescoped relationship in such a way that the actuator tube may be controlled to be retracted after positioning the ramp to engage the loadbed of a vehicle so that the actuator is not subject to forces exerted by the ramp during oscillatory movement while the vehicle is being loaded or unloaded. In one alternate embodiment the actuator is connected to an intermediate link to allow the pivotal movement of the ramp without exerting damaging forces on the actuator. The lip may be extended by a toggle linkage responsive to movement of the ramp from an elevated position to a declined position in engagement with the loadbed and a latch mechanism is operable to hold the ramp in an extended position until the loadbed is engaged. Ramp support legs are retractable to allow further declining movement of the ramp and are actuatable by a spring connected to a linkage which is moveable to positions to change the direction of spring biasing forces acting to retract and extend the legs.

Abstract: A simple, pore-level model for diffusion and NMR relaxation of oil-water mixtures in water wet pores has been developed. In addition to lending physical insight into the relaxation time behavior of mixed pore fluids, the  model can be used to generate a practical tool for interpreting diffusion lo g data, i.e., a T2 vs. D cross plot. Locating points on the cross plot simultaneously yields the near wellbore water saturation and the rock pore size. For light oils, T2 is shown to be mainly a pore size indicator whereas  D is controlled mainly by Sw. The pore size "resolution" decreases as oil viscosity and/or Sw decreases. A preliminary verification of the model has been made with limited core data and the results of applying the model to interpreting NMR log data are encouraging. The capability to separate the effects of pore size from fluid saturation on NMR response of pore fluids indicates an important potential advantage of the T2 and D measurement combination over standard T2 logging for characterizing formation pore size and related reservoir flow properties.

Title: Thermoplastic foam and process for producing it using carbon dioxide
Inventor: SCHIRMER HENRY G
IPC: C08J9/12
Filed: 1996-12-18
Granted: 2004-08-31
Abstract: The present invention provides a process for producing thermoplastic foam, including: (a) melting a thermoplastic polymer to produce a polymer melt; (b) introducing a carbon dioxide blowing agent into the polymer melt; (c) adding to the polymer melt one or more additives selected from the group consisting of (1) polysiloxane, and (2) mineral oil; and (d) extruding and foaming the melted polymer melt, blowing agent, and one or more additives to produce thermoplastic foam. The resultant thermoplastic foam can be thermoformed into various foamed articles, such as foam packaging trays. The quality of foams made from a carbon dioxide blowing agent, and particularly 100 % carbon dioxide, has been found to be substantially improved by adding one or more of the foregoing additives, i.e., polysiloxane, mineral oil and, optionally, polyolefin to the polymer melt during the extrusion and foaming process. Such foams have far less ruptured cells, surface cracks and corrugation than comparable foams made with a carbon dioxide blowing agent but which lack the additives of the present invention.
