Title: Apparatus for detecting deterioration of engine oil
Inventor: HOSONUMA KUNIHIKO
IPC: G01N21/35
Filed: 1989-11-17
Granted: 1996-07-23
Abstract: An apparatus for detecting the deterioration of an engine oil including a ceramic heater radiating infrared light including infrared radiation having a wavelength of 6.1 micron meters which is equal to the specific infrared absorption peak of ester of nitric acid contained in the engine oil.  The infrared light is made incident upon a photodetector via a band pass filter having a center wavelength of 6.1 micron meters to detect an amount of the ester of nitric acid contained in the engine oil.  It has been experimentally confirmed that an amount of the ester of nitric acid is proportional t the total acid value which is a measure of the deterioration of the engine oil, so that by suitably processing an output signal of the photo-detector, it is possible to detect the deterioration of the engine oil.  The thus detected deterioration may be displayed on a display device provided on a front panel of a car.

Patent CA-2012767-C (CA)
Inventor: PENTICOFF AMY M
IPC: C12P1/00
Filed: 1990-03-22
Granted: 1998-06-30
Abstract: A method for processing aqueous fermentation broths in a bioreactor vessel, in which a foam inhibitor is added to the fermentation broth in the bioreactor vessel in order to prevent the accumulation and buildup of foam in the bioreactor vessel caused by oxygen sparging of the fermentation broth contained therein.  The aqueous fermentation broth processed in the bioreactor vessel is conveyed as a feed solution to an ultrafiltration system including a membrane for concentrating the aqueous fermentation broth.  The ultrafiltration system is typically located downstream of the bioreactor vessel.  The improvement involves reducing the amount of fouling of the membrane in the ultrafiltration system by adding to the aqueous fermentation broth in the bioreactor vessel as the foam inhibitor, an antifoam which is an oil based liquid in the form of droplets, the droplets of the oil based liquid antifoam being dispersed, encased, entrapped and imbedded, within solid particles of a water soluble encapsulating material.

Title: Swap tank
Inventor: GERHARD HELMUT
IPC: B65D88/12
Filed: 1990-08-13
Granted: 1995-01-17
Abstract: SWAP TANK            Abstract of the Disclosure A swap tank has transverse bars disposed at the standard spacing of ISO containers and end portions extending beyond the transverse bars. Each end portion has associated with it a base frame structure including the said transverse bar and a pair of diagonal struts 14 which extend towards each other and are welded together at the tank end. A support member 24 is welded between the interconnected ends of the diagonal struts 14 and a ring 23 welded to the tank bottom 11 below the tank axis 21. The support member 24 is formed as an integral bent sheet metal part having two lateral triangular wall elements 26. To compensate for manufacturing tolerances, the support member 24 may be adjusted by varying the bending angle in such a manner that the free edges 27 of the triangular wall elem-ents 26 extend parallel and flush with the outwardly facing surface of the ring 23 and may be welded thereto. A structure is thus obtained which not only protects the projecting tank end but also serves to transmit longitudinal acceleration forces from the tank bottom 11 into the corner fittings 13 provided at the ends of the transverse bar.

Title: Process for the long term reduction of body fat stores, insulin resistance, hyperinsulinemia and hypoglycemia in vertebrates
Inventor: CINCOTTA ANTHONY H
IPC: A61K38/22
Filed: 1990-11-16
Granted: 1996-12-24
Abstract: A process for the long term modification and reg-ulation of lipid metabolism -- generally to reduce obesity, insulin resistance, and hyperinsulinemia or hyperglycemia, or both (these are the hallmarks of noninsulin dependent, or Type II diabetes) -- by ad-ministration (i.e., by feed or injection into the bloodstream) to a vertebrate, animal or human, of a dopamine agonist, e.g., bromocriptine. Administration of the bromocriptine is made over a limited period at a time of day dependent on the normal circadian rhythm of fat and lean members of a similar species. Decreases in body fat deposits result by treatment of an obese species on a daily timed sequence based on circadian rhythms of the peak prolactin, or peak pro-lactin and peak glucocorticosteroid, blood level established for lean members of a similar species. Insulin resistance, and hyperinsulinemia and hyperglycemia, or both, can also be controlled in humans on a long term basis by treatment corresponding to that of the treatment for obesity. The short term daily injections reset hormonal timing in the neural centers of the brain to produce long term effects.

Granted: 2001-03-20
Abstract: Effective amounts of low molecular weight brominated polystyrenes unexpected ly provide good property retention and yet achieve desired flame retardance, for example; UL-94 VO in high impact polystyrene. In contrast, high molecular weight brominated styrene polymers (degree of polymerization equals 2,000) do.not provide good  property retention such as impact strength and toughness in high impact polystyrene. The degree of polymerization of th e brominated polystyrenes of the present invention is generally from'about 3 to about 20 and can have a considerable variation in the amount of halogenation. The high impact polystyrenes blended with the low molecular weight brominated polystyrenes a re readily processed by conventional equipment.

Abstract: A switch is provided for selectively routing digital information packets received from at least first and second external sources to at least first and second external destinations. At least one of the first sources generates an information packet including a datum (or a request therefor) and a corresponding descriptor. First and second routing interconnects have inputs for receiving packets from respective sources and outputs for transmitting packets to respective destinations. The interconnects are also coupled for transferring packets between one another. Directories within the interconnects store descriptors corresponding to data associated with the first destination, as well as requests routed from the other interconnect. A controller routes packets based on the correspondence, or lack thereof, between the descriptor in that packet and an entry signal allocated to corresponding directory.

Title: Transfer printing process
Inventor: HALE NATHAN
IPC: B41M5/26
Filed: 1991-07-05
Granted: 1996-06-25
Abstract: An image (3) is permanently printed on an object (8) by capturing the image (3) printing heat sensitive ink solids by ther-mal mean onto a medium (9) and then transferring the ink solids from the medium (9) to the object (8) by applying sufficient heat to the ink solids to cause the heat sensitive ink to permanently bond to the object (8) in the desired image (3). The heat sensitive transfer ink is printed onto the medium (9) by thermal printing means (10) at a temperature which will release and print the ink, but which is below the temperature which will cause the heat sensitive ink to bond permanently.  The image (3) is then transferred from the medium (9) onto the object (8) at a higher temperature which will cause the sensitive ink to permanently bond to the ob-ject (8).

Granted: 1997-02-25
Abstract: A flange fitting for attaching to the lid of a drum includes a seal tube having a generally cylindrical main body with a relatively thin wall and an outwardly radiating frustoconical lip extension.  Also included as part of the flange fitting is a standard drum plug flange having a generally cylindrical main body and an outwardly radiating, frustoconical lip.  The drum plug flange is sized and shaped so as to fit within the seal tube such that the lip extension and the lip are generally coextensive with each other.  These two components are then able to be anchored into the lid of the drum through a punch press operation which simultaneously clamps and crimps both the lip and lip extension into a raised boss recess thereby precluding any preassembly, such as by welding, of the seal tube and drum flange prior to assembly to the drum lid.
