Title: Treatment of metals for coating or activation
Inventor: BALDI ALFONSO L
IPC: F42B12/70
Filed: 1990-09-13
Granted: 2000-12-05
Abstract: Coating with high-melting metals can be simplified by alloying high-melting metal with sufficient aluminum to make low-melting alloy that is applied, bonded in place, and then subjected to the leaching out of some or most of the aluminum. The resulting surface is porous and will receive and hold tap coatings as from spraying nozzles (12). Leached surface can be pyrophoric and top coating can be exothermically combustible. Pyrophoric powder can also be coated on boron or carbon fibers or sintered with combustible particles. Porosity can be created by subjecting workpiece to diffusion conditions in contact with depleting material such as powdered nickel or high-nickel aluminides or cobalt or high-cobalt aluminides. Aluminum particles can be electrophoretically deposited on foil and then diffused in. Leaching aluminum out with caustic is improved when a little H2O2 is present in the caustic in the leach tank (22). Subsequent treatment of the leached surface with weak acid further improves pyrophoricity, and folding of the pyrophoric member extends its pyrophorically-generated high temperature dwell. Resin foil containing pyrophoric particles makes effective decoy,

Inventor: FEARS CLOIS D
IPC: F16L57/00
Filed: 1992-09-01
Granted: 1998-08-04
Abstract: A method and material for the manufacturing or retrofitting of fluid transport systems.  The material chosen for the lining, or the pipe itself, will be selected based on physical properties such as a high impact strength and a low coefficient of friction.  The low coefficient of friction will be essential to prevent the initial adhesion of foreign substances to the inner surface of pipes.  In particular, an improved pipe composite will be useful in the lining or construction of water intake pipes where there is a well-recognized problem of the buildup of foreign substances including algae and other marine microorganisms.  Therefore, by preventing buildup, the present invention will provide a more economical and efficient method to maintain the overall piping system.

Abstract: READ-ONLY SEQUENCE CONTROLLER      A read-only sequence controller has a main circuit and a sub-circuit operated by a command signal from the main circuit at a predetermined cycle time.  The cycle time of the main circuit is longer than the sub-circuit in order to control the sub-circuit.  A sensor is provided on an outlet of a machine for detecting a discharge of a work at every cycle end and producing a discharge signal which is fed to the sub-circuit.  In normal operation, the sub-circuit is re-started in response to the discharge signal and the command signal from the main circuit.  When abnormality occurs, the sensor does not produce the discharge signal.  In response to absence of the discharge signal and to the command signal, a stop control circuit produces stop signals to stop the main circuit and the sub-circuit.

Abstract: Raster display memories are often arranged to output groups of pixels in progressive blocks, each having a plurality of pixels and each pixel having a plurality of fields. The fields in each, pixel may provide color, overlay and cursor information for an individual position on a video screen. The numbers of bits in each pixel and in each field may be variable in different applications. In this system, control information indicates the starting position of each block, the location of each pixel in each block and each field in each pixel and the width of each pixel and each field in number of bits. Using this control information, the system recovers the pixels in each block and the fields in each pixel and processes such information to provide a display of the pixel information on a video screen. The number of bits contained in each field may be expanded to a width (e.g. 8) when the field width is less than eight (8) bits. In this expansion, the expanded field value has an error, compared to the field value before expansion, less than half of the least significant bit in the expanded field. Frequently, the bits in each field before expansion are provided in the positions of greatest binary significance in the expanded field. The unused positions in the expanded field are then filled in the order of progressively decreasing significance by the bits of progressively decreasing significance in the field before expansion, starting from the bit of greatest significance.
