Abstract: A rotary joint for a decoking tool. The rotary joint includes a seal assembly that has one or more primary seals and one or more secondary seals. The secondary seals become operative upon the presence of a leak in the primary seals such that the rotary joint can continue to be used until a scheduled maintenance outage. A selective vent is used to route leaking fluid so that one or the other of the primary and secondary seals can be activated.

Abstract: The present invention is related to a method, system, and business process for configuration management of an item such as a network. A deployed state of being and a designed state of being for the item are identified. Configuration items in the states of being affected by the change request are identified. The incorporation of a requested change to the states of being is managed using a configuration management application. A pending state of being for the item is generated reflecting the requested change that identifies the configuration items in the states of being having at least one attribute of a configuration item affected by the change. Graphical models, displayable on a display, are generated of all three states of being allowing access to configuration item information, the status of the change, and approval/disapproval of the change.

Abstract: A lubricant flinger, for providing lubricant fluid to bearings on a horizontal shaft within a wet-sump bearing housing, has a rotationally balanced body with portions extending radially sufficiently to reach below a lubricant level in the wet-sump. The body has provisions for fixing it on the horizontal shaft and is capable of insertion, while mounted on the horizontal shaft, into the housing through a bearing bore of radius smaller than that of the body. Outer portions of the body may have features which enhance lubricant pick-up.

Abstract: A method of measuring physiological function of a group of body cells, includes the step of selecting a detectable agent capable of emitting a measurable electromagnetic emission. The agent is introduced into body fluid which contacts the group of body cells. The emission is measured, and physiological function is determined based on measurement of the emission.

Abstract: A system for lubricating bearings on a vertical rotatable shaft within a bearing housing, is comprised of an annular lower lubricant sump at a lower portion of the bearing housing; an annular upper lubricant reservoir at an upper portion of the bearing housing; and a conduit providing fluid communication between the lower lubricant sump and the upper lubricant reservoir. Provision is made for metering a flow of lubricant from the upper lubricant reservoir into upper bearings. The lubricant is pumped from the lower lubricant sump, through the conduit, to the upper lubricant reservoir at a rate exceeding the rate of metered flow into the upper bearings. A constant head of lubricant above the metering orifice is provided in the upper lubricant reservoir, as well as an outlet for shunting excess lubricant back to the lower lubricant sump.

Abstract: A reverse Galilean finder in which a front frame, preferably associated with a front element is projected away from the eye by the finder optics without separate frame projection optics to a position such that the distance between the apparent position of the frame to the eye and the rear vertex of the finder divided by the length of the finder is at least 2.2.

Abstract: A printer is disclosed for printing on plastic film which comprises a pivotal printer carriage carried by a printer frame of the printer. The printer carriage includes a thermal transfer print head and at least one driven ribbon roll for drawing an ink ribbon across the print head. The print frame includes a plurality of directional rollers which direct the plastic film to a driven platen roller and to a downstream driven film roller. The drives of the film and ribbon rollers are synchronized so that the film and ribbon are advanced in a superposed relation across the print head. The printer carriage is pivoted to a printing position from a non printing position by a rotary actuator. In the printing position, the platen roller which consists of an neoprene roller having a durometer of 45, is spring biased against the print head with a controlled spring rate, and with the film and ribbon sandwiched therebetween.

Abstract: The system of the present invention increases the resolution of an image that may be formed from an image sensor without increasing the resolution of the sensor. An image beam is directed along a path through a color filter wheel and a single non-rotating transparent plate and impinges on a CCD (Charge Coupled Device). A cam body with an angled surface rotates about the optical axis of the image beam and tilts the transparent plate in a plurality of discrete sampling positions. At each sampling position, the tilted transparent plate displaces the image beam in a different direction. Therefore, each pixel of the CCD samples a plurality of areas of the image. The color wheel is rotated to sequentially place each filter into the path of the image beam. The CCD sequentially receives the light passed through the transparent plate and color filter wheel and converts the image formed by the light to corresponding electrical signals.

The pulsing circuit offers a simple, flexible, and precise means of pump pulse control. Flashlamp simmer current is provided from the constant dc voltage source with a resistor in parallel with the switching transistor.

Abstract: Diffraction-limited output beam quality is achieved with a laser having an elongated homogeneous active medium pumped through two optically plane, parallel faces and situated within a resonant cavity defined by a plane reflector at one end and a concave spherical reflector at the opposite end. For a ray of optical energy passing through the active medium, there is a plane containing the ray in which the effective optical length in the medium is greater than the effective optical length in the orthogonal plane containing the ray. The separation between the cavity reflectors is selected to form a stable resonator in one of these planes and an unstable resonator in the orthogonal plane.
