Title: Polar Grafted Polyolefins, Methods for Their Manufacture, and Lubricating Oil Compositions Containing Them
Inventor: BODEN FREDERICK J
IPC: C10M167/00
Filed: 1995-10-20
Abstract: A grafted polyolefin containing one or more of N-vinylimidazole, 4-vinylpyridine, or other ethylenically-unsaturated nitrogen-containing or oxygen-containing graftable monomers grafted to a polyolefin copolymer is disclosed. The grafted polyolefin preferably has a weight average molecular weight of from about 20,000 to about 500,000, a polydispersity of less than about 10, and an ADT value of at least about 8. The grafted polyolefin can be defined as containing more than about 1.2% by weight of grafted monomer on a polyolefin, or as containing at least about 13 moles of graftable monomers per mole of polyolefin, or as having an asphaltene dispersancy test (ADT) value of at least about 8. Also described is a lubricating oil comprising a lubricant base oil and a grafted polyolefin as described above. Also described is a method of making a dispersant viscosity index improver. N-vinyl-imidazole or other ethylenically unsaturated nitrogen-containing and/or oxygen-containing graftable monomers and a graftable polyolefin are reacted with enough of an initiator to graft the monomer to the polyolefin. The initiator and/or graftable monomer is added to the other ingredients, maintained at the reaction temperature, over a period of time. The reaction temperature is maintained at a level high enough to give acceptable reaction times. The N-vinylimidazole and the initiator each can be added at a uniform, relatively slow rate during the reaction.

Title: Sending System for Detecting Presence of an Ink Container and Level of Ink Therein
Inventor: ALTFATHER KENNETH W
IPC: B41J2/125
Filed: 1996-09-16
Abstract: A low ink sensing system is combined with an ink cartridge detection system to enable a more efficient ink jet printer. An ink container which supplies ink to an associated printhead is modified by the incorporation of two light directing elements, in the preferred embodiment, a faceted prism and a roof mirror, into a transparent wall of the container housing. The cartridge, comprising the ink container and associated printhead, is mounted on a scan carriage. Periodically, the carriage is conveyed to a sensing station comprising a pair of light sources and a commonly used photosensor. A first light source is energized and a beam of light is directed to a location where the roof mirror, would be positioned if the cartridge is present. If the cartridge is absent, lack of a reflected return signal is sensed, indicating a cartridge has not been inserted. Print operation is halted until a cartridge is inserted. If a cartridge is properly inserted, the roof mirror returns most of the incident light to the photosensor which generates a signal indicating the presence of the cartridge. A second light source is then energized and directed towards the faceted prism, which is either immersed in ink or exposed to air within the interior of the container. If the latter, light is internally reflected by the prism facets back to the photosensor. If a print operation has been in progress, and the ink level has fallen, the common photosensor detects either a strong or weak redirected light component and initiates a status check and generates appropriate displays of low ink level or out of ink warnings.

Title: Article-information display system using electronically controlled tags
Inventor: FREDERICK W RICHARD
IPC: G06Q30/02
Filed: 1995-09-19
Abstract: A product information display system has electronic display tags for displaying pricing and product information for products in stores or warehouses. The electronic display tags are electromagnetically coupled to a conductor. A  control circuit is used to generate an information signal which contains a tag address and related data. A modulator circuit modulates an a-c. power signal with the information signal and applies it to the conductor for transmission to the display tags. Each of the display tags is equipped with a coil that is electromagnetically coupled to the conductor for picking up the signals carried by the conductor. A  demodulator is used to demodulate the signal picked up by the coil to obtain the original information signal. Each of the display tags is provided with a manually operated switch for initializing the tags with initial addresses transmitted by the conductor. A microprocessor in the electronic tag then compares the address contained in subsequent information signals with the address stored in the tag's memory. If the addresses match, the microprocessor further processes the information signal for visual display or verification functions. An electrical power system supplies a-c. power to the display tags. A main power distribution loop is connected to the power supply and is magnetically coupled to multiple branch power distribution loops which extend along selected groups of display tags for supplying power to those display tags.

Title: Improved receptacle for a shopping cart
Inventor: JOHNSON CAMERON
IPC: B62B9/26
Filed: 1997-05-12
Abstract: Abstract This invention is directed towards an improved receptacle for holding a beverage container for use with shopping carts which nest one within the other for storage. The receptacle of this invention is secured to the handle of the shopping cart so that the body of the receptacle extends generally horizontally to the handle and away from the shopping cart. The receptacle comprises a body having an upper surface and an aperture within the upper surface of a size and configuration to receive therein a beverage container. Depending below the aperture of the body of the receptacle is a stop pivotally secured to the body. The pivotal securement allows the stop to swing freely below the aperture yet support the bottom surface of a typical beverage container which rests thereon. This prevents the beverage container from falling through the aperture in the upper surface of the receptacle. Moreover, when like shopping carts are nested one within the other for storage, the pivotal connection of the stop to the body allows the stop to swing freely out of the way. The receptacle thus avoids impeding the nesting of like shopping cart for storage.

Abstract: La présente invention concerne un procédé destiné à l'élimination du cholestérol, des triglycérides ou autres lipides d'un plas ma ou d'un sérum d'animal ou d'autres fractions sanguines appropriées, selon un système à écoulement discontinu. Ce procédé consiste à prélever du sang sur un patient, à séparer la fraction nécessaire de sang et à mélanger celle-ci avec un mélange de solvants qui extrait les lipides de ladite fraction, après quoi la fraction délipidée est recombinée avec les globules sanguins et renvoyée au patient. Ce procédé se caractérise en ce que l'opération d'extraction du solvant est effectuée séparément et à distance du patient. La fraction délipidée est lavée avec un second solvant avant d'être recombinée avec les globules sanguins. De façon à s'assurer que la fraction délipidée ne contient plus aucun solvant d'extrac tion, ladite fraction est mélangée à un absorbant spécifique du solvant que l'on extrait. L'absorbant préféré est constitué d'une bille polymère macroporeuse contenue dans les pores d'une sphère en verre fritté ou en plastique, ladite bille étant capable d'absorber les molécules organiques d'une solution aqueuse. Le traitement du plasma, du sérum ou d'une autre fraction sanguine adaptée d'un patient au moyen de ces procédés, permet d'améliorer la rhéologie sanguine chez le patient présentant une mauvaise circulation sanguine. De plus, on assiste à une régression rapide de l'arthérosclérose coronarienne.
