Abstract: A fuel injection system includes an injector body that defines a nozzle outlet connected to a nozzle supply passage having a flow restriction. A source of fuel at a supply pressure is in fluid communication with the nozzle supply passage. A needle valve member is positioned in the injector body and is moveable between an open position in which the nozzle outlet is open, and a closed position in which the nozzle outlet is blocked. The supply pressure is of a magnitude and the flow restriction is of a size that the needle valve member moves cyclically between its closed position and its open position.

Abstract: A bounce depression device 29 for a high speed poppet valve 11 in a electronically controlled hydraulically operated unit fuel injector 1 comprises a poppet valve 11 with a central bore 35 and a counter bore 33 having a flat inner end 37 and a annular grove 39 on the other end which receives a retainer ring 41 that holds a plurality of flat washer shaped damping rings 31 in the counter bore 33 to absorb momentum by rattling and bouncing as the poppet valve 11 seats to prevent the poppet valve 11 bouncing off the seats 13 and 15.

Abstract: A fuel injector having a plurality of spaced apart apertures modifies the rate of fluid flow of the fuel injectors. The apertures are sequentially opened by movement of the intensifier piston in a piston bore passing actuating fluid flow at an increasing rate to a piston pressure chamber defined by a first end surface of the intensifier piston, a closed end surface of the piston bore and the cylindrical surface of the piston bore. The opening of the spaced apart fluid delivery apertures provide a stepped rate trace. The stepped rate trace allows less fuel to be injected into the combustion chamber by injecting the fuel slower during the early phase of the combustion process where combustion is less harsh.

Abstract: A hydrocarbon feed pipe in a fluid catalytic cracking system includes a nozzle positioned in the upper section of the riser reactor pipe. This arrangement, together with one or more feed pipes at conventional locations in the riser reactor pipe, allows for feed segregation or feed splitting processes whereby different feed flow rates and/or compositions are fed to different points in the riser reactor pipe. Feed splitting/segregating processes provide for improved product yields and product properties.

Abstract: A fluid catalytic cracking unit equipped with multiple feed injection points along the length of the riser is operated such that all of the fresh feed is charged to one of different feed injection points, depending on the ratio of light distillate (gasoline) to middle distillate (light catalytic gas oil) that is desired in the product slate. When all of the fresh feed is charged to one of the upper injection points in the riser in order to increase middle distillate yield, the unconverted slurry oil (650.degree. F.+material) can be recycled to a location below the injection point of the fresh feed so as to increase conversion to middle distillate while lowering the activity of the catalyst (via coke deposition) for single pass conversion of the fresh feed. Steam in excess of levels typically employed for dispersion is used at the bottom of the riser to lift the regenerated catalyst up to the feed injection points.

Abstract: A process for rapidly forming a laminar ceramic shell mold on a supporting structure comprising alternately, in either order, the steps of: (1) dipping the support structure into a bath comprising either an alkali stabilized solution of ionic silicate or an alkali stabilized solution of colloidal silica to define a first coating on the support structure; and (2) dipping the support structure into a bath comprising an acid stabilized solution of phosphate modified aluminum salt to define a second coating on the support structure. The coatings on the support structure react to form a gel set shell which can be fired to create a ceramic material. The dipping step sequence is repeated to provide additional coatings which react to define additional layers of gel set shell. The rate of laminate thickness buildup can be increased by including fine particulate refractory in the coating baths and the coated surface can be contacted by dry, relatively coarse refractory to define a stucco layer between the dip coatings.

Abstract: Device for immobilizing a patient's limb. The device comprises an elongated, three-sided, resilient support member of generally U-shaped cross-section, open at the top and comprising a base or bottom wall and a pair of side walls extending upwardly from the base, and fastener means extending from one side wall to the other across the open top of the support member. The support member is preferably made of a closed cell plastic foam material, coated with a thin adherent washable coating. The side walls are preferably perpendicular to the base, defining an opening of rectangular cross-section for receiving a patient's limb or portion thereof. Fastener means may include either a plurality of transversely extending straps (preferably Velcro) or a plastic sheet having means (such as short Velcro strips) which will engage the side walls.

Abstract: A video endoscope aperture wheel drive system effective to position a predetermined aperture formed in an aperture wheel in an optical path of an image generated by an imaging device viewing an object, while eliminating oscillation of the aperture wheel caused by the rotational stepping of the aperture wheel in either direction in response to movement of a video probe in which an imaging device is positioned. The aperture wheel motor is rotated clockwise or counter-clockwise in response to the proximity of the imaging device relative to the object being viewed.

Abstract: A cover for use in covering a seat, such as an automobile bucket seat, is provided which includes a nonstretchable portion that covers the forward surfaces of the seat bottom and back, and a stretchable skirt and cap that permits the cover to be adapted to fit a variety of sizes of bucket seats including both those of the high-back and low-back variety. The cover includes the cap, which covers at least a portion of the high-back bucket seat. The cap is stretchable widthwise to accommodate the wider width of a low-back seat and the cap, as it stretches widthwise, simultaneouly decreases in vertical dimension thereby decreasing the overall length of the seat cover so that it more closely fits a low-back bucket seat. In the preferred embodiment, the nonstretchable portion of the seat cover is a sheepskin, while the stretchable portions are made of a wool cloth having a nap similar to the nap of the sheepskin.
