Title: Process for depositing hard coating in a nozzle orifice
Inventor: FLYNN PAUL L
IPC: C23C16/04
Filed: 1991-03-14
Granted: 2000-11-28
Abstract: The present invention is directed to a process for coating the interior surfaces of an orifice in a substrate that forms a slurry fuel injection nozzle. In a specific embodiment, the nozzle is part of a fuel injection system for metering a coal-water slurry into a large, medium-speed, multi-cylinder diesel engine. In order to retard erosion of the orifice, the substrate is placed in a chemical vapor deposition (CVD) reaction chamber. A reaction gas is passed into the chamber at a gas temperature below its reaction temperature and is directed through the orifice in the substrate. The gas reaction temperature is a temperature at and above which the reaction gas deposits as a coating, and the reaction gas is of a composition whereby improved resistance to-erosion by flow of the particulates in the slurry fuel is imparted by the deposited coating. Only the portion of the substrate in proximity to the orifice to be coated is selectively heated to at least the gas reaction temperature for effecting coating of the orifice's interior surfaces by the vapor deposited coating formed from the reaction gas.

Title: Pixel interlacing apparatus and method
Inventor: DEMOS GARY
IPC: G06F3/14
Filed: 1992-02-07
Granted: 2003-04-29
Abstract: An image processing system uses a pseudo-random pixel interlace method and apparatus for capturing groups of pixels as image frames. This pseudo-random method eliminates the artifacts commonly present in standard regular line raster scan imaging systems. Moreover, the pixel interlacing method permits the construction of higher resolution frames from a series of orthogonal lower resolution frames. An enhancement circuit deduces information from previous pixel group frames and contributes additional detail to the pixels of the frame being processed. The format of the pixel interlaced groups permits the present invention to be used in a wide variety of normally incompatible target display rates. The present invention can also be used in a computing system as an auto-synchronizer for processing signals from different sources.

Title: Mobile-telephone system call processing arrangement
Inventor: STROM KENNETH WAYNE
IPC: H04J3/06
Filed: 1992-04-21
Granted: 1997-12-23
Abstract: A CDMA cellular radio-telephone system (FIG. 2) comprises a packet-switched communications network (202, 207, 201) that interconnects cells (base stations; 202) with each other and with the public telephone network (100). A unique combination of a static addressing plan that uses a different LAPD DLCI (302 in FIG. 7) for each unidirectional virtual call path, direct cell (202)-to-cell and cell-to-call-processing unit (264 in FIG. 5) control information exchanges, and packet-switching techniques that permit call traffic and control communications to share call paths and permit different call paths to share physical resources, is applied to call processing. This enables soft handoffs (FIGS. 27-29) to be handled in a manner transparent to the parties to the call and without significant involvement of system control elements (134 and 261 in FIG. 2) whose involvement would adversely impact the system's call-handling capacity. It also enables soft handoffs to occur without change of the call processing unit that is handling the call, so that a single call processing unit continues to handle the call from start to finish through even multiple soft handoffs.

Granted: 1998-08-11
Abstract: A method and apparatus for cooling a heat load in which a pressure vessel is provided to contain a cryogen as a saturated liquid   and   saturated   vapor   separated   by   liquid-vapor interface.  The pressure vessel has an inlet adapted to receive a  subcooled  liquid  cryogen  and  thereby  convert  it  to  a saturated liquid through contact with the saturated vapor.  A heated overflow tube projects into the pressure vessel and is level, at one end, with the liquid-vapor interface so that any increase in the saturated liquid overflows into overflow tube and  is  vaporized  to  form  the  saturated  vapor.   The  heat transfer and the reintroduction of the vaporized liquid can be effected  through forced circulation provided by  an  ejector. Preferably the pressure vessel is provided with two outlets for discharging  the  saturated  cryogen  as  saturated  liquid  or vapor.  One or more ejectors having high pressure inlet(s) in communication with the two outlets of the pressure vessel are provided  for  drawing  the  heat  transfer  fluid,  after having cooled the heat load,  into a heat transfer relationship with the overflowed saturated liquid and then into mixture(s) with the  saturated  liquid  or  saturated  vapor,  or  both  and  for discharging  the  same out  of  a  high pressure  outlet  of  the ejector to the heat load.

Abstract: A radio paging receiver enables an user of the receiver later to see a received message even when an alert stopping operation or message confirmation operation is first executed in an environment too dark to see the received message. The receiver has a photosensor for detecting whether a display environment is light or dark. If the alert stopping operation is executed in the dark condition, the received message is stored in a memory as an unconfirmed message, so that the user later can see and read the received message in a light condition after a change of the environment. In addition, when the environment is changed from a dark condition to a light condition, if an unconfirmed message exists in the memory, the receiver alerts the user.

Abstract: A system and method for performing long range, non-linear, sector scan panoramic electro-optical reconnaissance of a scene from an airborne craft. According to the present invention, the reconnaissance can be performed at increased aircraft velocities with a given detector technology at a desired level of performance. The system according to the present invention comprises a focal plane array that is configured to detect an image of the scene, and to convert the image into electronic charge information representing the image, a main electronics unit that converts the electronic charge representation into an electronic signal which is a digital representation of the image. A lens arrangement is used to focus a narrow slit of the scene onto the focal plane array, and a rotating prism scans the slit across the scene at a non-linear scanning velocity as determined according no the present invention. The electronic signal is transmitted to a ground station where it is processed to provide visual image data and that represents the scene, distortion induced into this data as a result of the non-linear scan velocity is removed to provide a distortion free final image.
