Inventor: GERAETS JACQUES J M
IPC: G03G15/20
Filed: 1989-10-27
Abstract: A fixing device for fixing a powder image on a receiving sheet in a fixing nip formed by a fining roller and a pressure roller which has a lower flexural stiffness than the fixing roller. These rollers are pressed against one another by a stationary cushion filled with compressed air and pressing against the pressure roller in a pressure zone situated opposite the fixing nip. When the pressure roller and the fixing roller are driven, tangentially directed frictional forces are exerted on the pressure roller that causes the presssure roller to deflect against a curved support surface which limits the deflection. The pressure roller deflected in the operative position causes a receiving sheet fed through the fixing nip to be stretched in a direction transversely of the direction of conveyance to eliminate any bubbles or corrugations in the receiving sheet.

Title: Moving-bed regeneration of hydrocarbon conversion with variable regeneration gas flow
Inventor: KOVES WILLIAM J
IPC: C10G35/12
Filed: 1989-11-14
Abstract: "MOVING-BED REGENERATION OF HYDROCARBON CONVERSION CATALYST WITH VARIABLE REGENERATION GAS FLOW"                  ABSTRACT Spent hydrocarbon conversion catalyst is regenerated in a variable gas flow regeneration apparatus in which catalyst particles are confined in a vertically-elongated movable bed and therein contacted with a hot oxygen-containing gas stream in order to remove, by means of combustion, coke which accumulated on the catalyst particles while they were used in a hydrocarbon conversion zone. The catalyst particles are confined in the bed by means of catalyst retention screens. The catalyst retention screens are configured such that gas flow through the bedvaries from a maximum at the top of the bed to a minimum at the bottom of the bed. The variation in gas flow is accomplished by varying the size and/or number of gas flow apertures in one of the retention screens so that the effective cross-sectional area available for gas flow through the screen varies from a maximum at the top of the bed to a minimum at the bottom of the bed. The varying gas flow pattern results in the delivery of oxygen in a manner which more closely matches the oxygen requirement for combustion at each point in the bed, thus increasing the coke burning capacity of the bed. Catalytic reforming is an example of a hydrocarbon conversion process in which the invention may be advantageously employed.

Patent CA-2019600-A1 (CA)
IPC: H04L1/00
Filed: 1990-06-22
Abstract: ABSTRACT OF THE DISCLOSURE      A multiple access satellite communication system in which a plurality of mini-earth stations each transmits data packets to a hub earth station via a satellite over an inbound channel, while the hub station transmits to the mini-earth stations in a broadcast mode over outbound channels.  Each mini-earth station selectively uses a fixed assignement access method, random access method, and demand assignment access method, depending on the frequency of the transmission from a terminal connected thereto, the amount of transmitted data, and whether or not the transmission from the terminal is periodic.  The hub station outputs a reception response signal to the outbound channels by determining whether or not a conflict of data packets or a transmission error has occurred on the inbound channels.  Packets for re-transmission are sent out to the inbound channels by the demand assignment access method at all times, with no regard to the access method used at the time of transmission.

Abstract: PROCESS OF PREPARING A TABULAR GRAIN            SILVER BROMOIODIDE EMULSION AND            EMULSIONS PRODUCED THEREBY            Abstract of the Disclosure A process is disclosed for the preparation of a tabular grain silver bromoiodide emulsion in which silver bromoiodide laminae are formed on the major faces of the tabular grains.  The sensitivity of the emulsion as a function of pressure applied is rendered more nearly constant by forming the silver bromoiodide laminae on the major faces of the tabular grains within a pAg and temperature range defined by Curve A in Figure 1.  The laminae are formed by first precipitating iodide as a silver salt at peripheral sites on the tabular grains and then precipitating silver bromoiodide onto the major faces of the host tabular grains with the primary source of iodide being the previously deposited iodide.  The emulsions produced exhibit high sensitivity to exposing radiation and reduced sensitivity to localized pressure.

Title: In situ soil decontamination method and apparatus
Inventor: NELSON JOSEPH M
IPC: E21B43/30
Filed: 1990-12-12
Abstract: Disclosed is in situ decontamination methods and apparatus for injecting a hot gas into boreholes formed in a contaminated soil area to vaporize the soil moisture and contaminants, and for collecting the vaporized contaminants at the surface of the soil. A burner heats pressurized gases and mixes the same with combustion gases for injection into the contaminated zone. A central collection system recovers the vaporized contaminants and couples such vapors to an on-site incinerator for disposal. Controlled heating of the injection gas is effective to sequentially remove different types of contaminants, as well as to provide in situ oxidation of other contaminants, while minimizing recondensation of the soil vapors. Wellbore casings are especially adapted for injecting the gas in predetermined patterns. In addition, a heater and incinerator assembly utilizes a single burner for both heating the dry gas and for incinerating.the vapor contaminants.
