Title: Insulating rigid polyurethane foam compositions
Inventor: WHITE WALTER R III
IPC: C08G18/48
Filed: 1996-08-05
Abstract: There is now provided storage stable polyol compositions and polyisocyanate based rigid closed cell foam made by reacting an organic isocyanate with polyol compositions in the presence of a blowing agent, where the polyol composition contains at least: a) an aromatic amine initiated polyoxyalkylene polyether polyol having an hydroxyl number of 200 meq polyol/g KOH or more; b) an aliphatic amine initiated polyoxyalkylene polyether polyol having an hydroxyl number of 200 meq polyol/g KOH or more; and the blowing agent is at least cyclopentane in an amount of 7 weight percent or more based on the weight of the polyol composition; and further, the cyclopentane blowing agent is soluble in the polyol composition, and the amount of the aliphatic amine initiated polyoxyalkylene polyether polyol is 10 weight percent or less based on the weight of the polyol composition. The polyol composition is adapted to solubilize cyclopentane in the polyol composition without sacrificing, and advantageously improving, the thermal insulation and dimensional stability of the resulting polyurethane foam. It was surprising to discover that less than 10 weight percent of the aliphatic amine initiated polyol was need to accomplish these objectives, and it was further surprising to discover that the aromatic amine initiated polyether polyol improved the thermal insulation of the foam.

Title: Universal epdm/butyl compound for use as an elastomeric barrier in water storage and treatment systems and the like
Inventor: MITCHEL JULIAN
IPC: C08K5/00
Filed: 1996-10-16
Abstract: A universal elastomeric compound whose improved features display excellent permeability while simultaneously having above average chlorine compatibility. This improved elastomeric compound comprises a measured quantity of a terpolymer of ethylene-propylene-non-conjugated diene copolymer (i.e. EPDM, e.g. ROYALENE*3180), chlorinated Isobutylene (e.g. Chlorobutyl*1066), furnace or carbon black (e.g., N-550*Black), paraffinic oil (e.g., Sunpar*150 Oil), organofunctional magnesium silicate (e.g., Mistron*      CB), magnesium oxide (e.g., Maglite*D Bar), zinc oxide, stearic acid, tetramethylthiuram disulfide (e.g., TUE*, zinc thiophosphate (e.g., ROYALAC*136), and treated sulfur (e.g., Spider*Sulfur). Adding a specified quantity of said ROYALAC 136, TUEX, and Spider Sulfur to the EPDM/butyl compound imparts low taste and odor to water. Additionally, adding a specified quantity of said Mistron CB to ROYALENE 3180 and Chlorobutyl 1066, provides for an elastomeric compound having excellent resistance to chloramines.      Because the herein prescribed combination of EPDM, butyl and other disclosed compositions exhibits low gas permeability, a high degree of chlorine compatibility, imparts low taste and odor to water, exhibits good flex characteristics, in addition to yielding extractants below the requirements of ANSI/NSF Standard 61 Health Effects Standard, the compound can be effectively used as an elastomeric barrier (e.g., a * Trademark diaphragm structure) in water storage and treatment systems, valves, pumps or the like.

Inventor: BIRCH G PAT
IPC: G01F23/02
Filed: 1997-02-12
Abstract: A sight glass for a fluid vessel that includes a housing with facility for mounting to a fluid vessel wall, and a transparent window mounted within the housing for viewing fluid within the vessel from outside of the vessel wall.

Title: Electronic controller for identifying and operating an automated manual transmission
Inventor: WHEELER JAMES A
IPC: F16H61/00
Filed: 1997-02-26
Abstract: An electronic controller for use in a partially or fully automatic vehicle transmission. The transmission includes an automatic shifting mechanism for partially or fully automating the shifting thereof to select and engage gear ratios. The automatic shifting decisions are made by an electronic control circuit including an electronic controller which receives electrical signals representative of the rotational speeds of the input and output shafts of the transmission. An algorithm is performed by the electronic controller to identify the structure of the underlying transmission and adopt an appropriate shifting strategy based upon the rotational speeds of the input and output shafts of the transmission. Initially, the electronic controller determines if the transmission is, in fact, engaged in a gear ratio. Once it has been determined that the transmission is engaged in a gear ratio, the electronic controller determines what the specific magnitude of that gear ratio is. Next, the electronic controller identifies a particular structure for the transmission based upon a plurality of sensed gear ratios. The electronic controller may employ principles of fuzzy logic to assist in identifying the underlying transmission structure. Lastly, the electronic controller adopts a shifting strategy which is appropriate for the identified transmission structure for use in performing subsequent automatic shifting functions.
