Filed: 1989-03-25
Abstract: A scroll-type hermetic compressor is disclosed including within a hermetically sealed housing (12) a fixed scroll member (48), an orbiting scroll member (50), a main bearing frame member (52), and a crankshaft (32). An oil sump (36) is located in a discharge pressure chamber (110) in the housing. The crankshaft is journalled by bearings (72, 74, 86) in the frame member and the orbiting scroll member. A centrifugal oil pump (38) supplies lubricating oil from the sump to the bearings through an axial passageway (120, 122) in the crankshaft. A vent (142, 144, 146, 148) allows the pumped oil to return to the sump to reduce leakage of oil and refrigerant into regions (98) at suction pressure.

Abstract: An internetwork communication system provides communication from a first local area network to a second, ring-type, local area network via a bridge. The bridge receives a frame from the first local area network and transmits a dummy frame followed by an internetwork transfer frame to the second local area network. The internetwork transfer frame defines a node of the second local area network as a distant apparatus (receiver) and a node of the first local area network as a self apparatus (sender). The bridge later receives the dummy frame from the second local area network, after transmission of the dummy frame around the ring, and deletes the dummy frame and the internetwork transfer frame received following the dummy frame so that the communication in the second local area network does not circulate indefinitely around the ring. As an alternative to using a dummy frame, the bridge can receive the internetwork transfer frame, after circulation around the second local area network, and compare the distant apparatus of the received internetwork transfer frame with a stored distant apparatus address. When the received distant apparatus address matches the stored distant apparatus address, the bridge deletes the internetwork transfer frame from the second local area network.

Abstract: Dewaxing aids used to assist in the solvent dewaxing of waxy hydrocarbon oils are recovered from the dewaxed oil or waxy precipitate, or both, by selective permeation of the oil or wax through a perm-­selective polyimide ultrafiltration membrane, under ultrafiltration conditions, leaving a retentate of dewaxing aid, of reduced oil and/or wax content, which dewaxing aid-rich retentate can be recycled to the solvent dewaxing process. 
     The polyimide ultrafiltration membranes are preferably produced using a casting solution of polyimide polymer dissolved in a dual solvent system comprising a pro solvent/anti-solvent pair at a ratio of 10:1 to 1:1 and further containing an inorganic salt, said casting solution being used to produce a film which is permitted to evaporate for 1 to 60 seconds and then quenched in a quenching solvent.

Abstract: Low heating value liquid hydrocarbonaceous and/or solid carbonaceous hazardous waste materials from the production, refining and marketing of petroleum products are destroyed without contaminating the environment while simultaneously gaseous mixtures comprising H₂ + CO i.e. synthesis gas, reducing gas, or fuel gas are produced. From about 0.3 to 2.0 wt. % of an anionic surface active dispersant and water (if needed) are mixed with the hazardous waste material to produce a first aqueous mixture. A comminuted solid carbonaceous fuel i.e. coal, petroleum coke is mixed with water and from about 0.02 to 1.00 wt. % of the dispersant to produce a second stable pumpable aqueous slurry. The first and second aqueous slurries are mixed together to produce a stable pumpable final blend aqueous slurry which is reacted in a partial oxidation gas generator as the feedstock. It was unexpectedly found that to achieve slurries with satisfactory rheological properties from mixtures of hazardous waste material and coal or coke slurries, it was necessary to add the dispersant to the coal/coke slurry as well as to the slurry of hazardous waste material before combining the two aqueous mixtures together.

Abstract: The present invention relates to a number of innovative electrophilic substitution reactions involving 2,5-dithienylpyrrole (2,5-DTP). More specifically, these reactions are used in the synthesis of monomers for preparing functionalized conducting organic polymers. 
     The electrophilic substitution reactions in this invention are accomplished under conditions not requiring the use of N-1 pyrrole blocking groups to direct reaction at the pyrrole C-3 position. This is because the steric bulk of the 2,5-dithienyl groups prevent N-acylation and therefore direct reactions with electrophiles at the pyrrole C-3 position. 
     The reaction conditions chosen have also demonstrated a greater regioselectivity towards functionalization at the pyrrole 3-position that the basic reaction conditions suggested in the prior art. This result may be explained by an activation of the pyrrole 3-position towards electrophilic substitution. This is attributed to an electron donating resonance contribution of the 2,5 thienyl groups. 
     Other advantageous reaction conditions have been discovered which direct electrophilic substitution preferentially at the pyrrole or thiophene groups depending upon the amount of acidic catalyst.

Abstract: Red blood cells which are infected with the parasite P. falciparum cause the cells to become sticky and less deformable. This results in a build-up of cells on the vascular wall and creates occulsions to blood flow which are thought to cause the cerebral, renal and liver complications of P. falciparum infections. Certain esters of castanospermine prevent or reduce the adhesion of falciparum infected blood cells to the vascular endothelial wall and are a useful adjunct in the treatment of malaria.

The active material is then dispersed or emulsified in the aqueous solution so that the active material has a primary particle size of between approximately 0.1 and 10 microns. The resulting dispersion or emulsion is then spray dried at a temperature between approximately 50° and 220° C. so as to microencapsulate the active material in the polymer. Compounds for promoting the rapid solidification of the active material are also disclosed.
