Title: Moisture separation in turbine interstage steam flow
Inventor: BLACK JAMES C
IPC: F01K7/16
Filed: 1992-05-07
Abstract: ABSTRACT OF THE DISCLOSURE     Any moisture present in a steam flow outletting from a high pressure steam turbine and before that flow is passed to the inlet of a low pressure turbine, is removed by passing the flow through a high velocity separator, this separator being a type in which at entry thereto vanes cause vortex-like swirling of the steam flow so that moisture therein is centrifuged against an inner wall surface of a separator housing from thence being carried forward in flow direction to outlet from the housing via a skimmer slot in the housing wall located intermediate the housing ends. The steam flow from which the moisture has been separated, passes to an outlet end of the housing but before making its exit therefrom passes through straightening vanes which reorient the flow from vortex-like swirling to longitudinal straight line course thereof.

Title: Method and apparatus for casting an arc melted metallic material in ingot form
Inventor: LILLQUIST ROBERT D
IPC: B22D11/041
Filed: 1992-05-07
Abstract: METHOD AND APPARATUS FOR CASTING AN ARC MELTED            METALLIC MATERIAL IN INGOT FORM                 Abstract of the Disclosure A method and apparatus for casting a molten metallic material in ingot form are provided wherein the molten metallic material is transported to the ingot mold and an upper surface temperature and temperature distribution of the molten metal pool in the casting mold are measured by an imaging radiometer which is disposed external to an inert gas filled chamber enclosing the ingot mold, and is disposed to view the ingot pool surface through a sight port.  At least plasma arc torch is employed to direct an arc at the ingot pool surface, the intensity of which is selectively modulated and the impingement of the arc is simultaneously selectively positioned in order to maintain a desired preselected mold pool surface temperature and temperature distribution thereby yielding a preselected metallurgical structure in the solidified ingot.  The imaging radiometer may provide a video signal as an output, and may be connected to a video analyzer and video monitor which are used to provide an image of the surface temperature and temperature distribution, enabling an operator to control the plasma arc torch in performing the ingot casting method.

Title: Transverse gradient coils for imaging the head
Inventor: ROEMER PETER B
IPC: A61B5/055
Filed: 1992-06-04
Abstract: RD-20,936 TRANSVERSE GRADIENT COIL FOR IMAGING THE HEAD                        ABSTRACT    Apparatus for producing a magnetic field gradient for magnetic resonant imaging of the head of a subject employs two fingerprint coils disposed apart from each other, creating a generally cylindrical cavity in which subject's head is placed.  A power supply provides current through the two fingerprint coils.  The fingerprint coils are comprised of concentric current-carrying paths with each path being elongated along the length of the cylindrical cavity on only one end. The shape and geometry of the fingerprint coils create a magnetic field gradient that has high linearity inside the cavity, and monotonically decreases outside the cavity, thereby minimizing artifacts introduced by the body of the subject.

Abstract: ABSTRACT OF THE DISCLOSURE            In a gas turbine combustion chamber which surrounds the rotor as an annulus and therefore has the shape of an annular combustion chamber,  the  front wall  (10)  is equipped with a number of burners whose ends occupy a uniform plane.  These burners form a double ring (10b, 10c) on the front wall (10).   In each ring, the same direction of rotation is present in the burners and this is opposite to the adjacent ring.  In addition, two burners at a time are alternately displaced out wards and inwards in each ring in order to achieve a favorable flow field for combustion.   The number of burners on the front wall (10) is divided into a larger quantity of piloting burners  (A1, A2)  and a smaller quantity of piloted burners (B1, B2).

Patent CA-2086331-A1 (CA)
Inventor: DUNK MICHAEL P
IPC: G01R31/58
Filed: 1991-06-21
Abstract: A faulted circuit detector (10) having an electrically isolated and remotely positioned indicator (14) detects fault currents in a monitored conductor (18). When a fault of a predetermined magnitude is detected, a light pulse is transmitted from the detector to the indicator via a fiber optic cable (15) where, upon receipt, the pulse is converted to an electrical pulse causing the indicator to indicate a "fault" state. A reset circuit (56) within the indicator resets the indicator at regular intervals to the "normal" state as long as a predetermined minimum voltage is present on the monitored conductor.  The detector includes a temperature compensation circuit (150) and low pass filter circuit (160) so as to prevent misoperation due to varying ambient temperatures or high frequency transients. A test circuit (48, 50, 34) is also provided to allow service personnel to field-test the device with the monitored conductor in an energized state.

Abstract: The relay is preferably used as polarity reversal relay for operating direct-current motors in two directions. 
<??>It consists of two electromagnetic systems (A, B) which are combined in a common housing, their contacts (5, 6, 7) being connected in a so-called "H-bridge circuit". Each of the two electromagnetic systems has a moving contact element (5), whereas both systems together exhibit a common pair of countercontact elements, namely a normally-closed contact element (6) and a normally-open contact element (7). Both electromagnetic systems each have a coil former (1) which are preferably of identical construction and are attached to one another by means of the common countercontact elements (6, 7) so that no additional mounting elements are needed. This keeps down the number of parts; the type of mutual attachment also largely reduces the expenditure for adjustment.

Title: System and method for image mapping in linear space
Inventor: EDGAR ALBERT D
IPC: G09G5/06
Filed: 1993-04-13
Abstract: ABSTRACT                SYSTEM AND METHOD FOR IMAGE   MAPPING IN LINEAR SPACE            Red, green and blue pixels of a digitized image are combined to form a single vector that points to three lookup tables translating each pixel  to linear Y,  I,  Q values thereby forming a linear image.  The color value of each pixel in the linear image, comprised of Y, I, Q "aim" values, is then sequentially processed to attempt a match to the closest available colors. These three aim values point to respective lookup tables which translate them to three corresponding intermediate numbers which, when summed, point to a larger table mapping them to a number corresponding to the closest color  in the predetermined palette.  Three  lookup  tables translate  the map number back to  the  linear  space with corresponding mapped Y, I, Q values. The difference between these values and prior aim values constitutes error arising from  the finite  palette.  The  error  is  corrected  with opposite  error  of  adjoining  pixels  by  error  diffusion techniques.  In one embodiment, the error alters the linear Y, I, Q values of yet unmapped pixels prior to their being converted to aim values. The linear image is precalculated so that error-correcting addition or subtraction is made prior to the pixel's conversion. In another embodiment, the value to add or subtract is stored in an array so that it may be added when the pixel is converted.
