Abstract: A static converter circuit has a voltage summing transformer (Tr-Tr13) with several part transformers (Tr1-Tr13) the static-converter-side winding of which are connected via one four-quadrant actuator each to a direct-voltage link circuit. The four-quadrant actuators are single-phase bridge circuits with one GTO thyristor each and a diode, which is antiparallel thereto, per bridge branch. The static-converter-side windings of the part transformers can be short circuited in each case by means of an alternating-current circuit breaker with antiparallel-connected thyristors. Each part transformer has a separate core. The power-system-side windings of the power transformers are connected in series and are connected at their ends to a railroad power system with 162/3-Hz. The direct-voltage link circuit is connected via power-system-commutated static converters and a static converter transformer to a national power system with 50 Hz. For generating an approximately sinusoidal alternating voltage part voltages of equal amplitude which are supplied by the part transformers are added and/or subtracted step-by-step in the voltage summing transformer. Each thyristor of a four-quadrant actuator is turned-on and turned-off at the most, twice per period of the alternating voltage. This reduces power losses and expenditures for cooling the semiconductor components. The static converter circuit is suitable for frequency converters and reactive-power compensators.

Abstract: A process for profile control in a high permeability zone of a formation.  A water flooding or carbon dioxide stimulation enhanced oil recovery (EOR) process is conducted in an oil-containing formation having a high permeability zone.  After breakthrough occurs, the EOR process is ceased.  The high permeability zone is heated to a temperature of 300°F or higher by steam injection.  Subsequently, steam injection is ceased and a temperature activated mixture is injected into the high permeability zone where it forms a solid gel.  Thereafter, an EOR process can be used to remove hydrocarbons from a low permeability zone.

Title: Directional comparison blocking protective relay system
Inventor: LI HUNG JEN
IPC: H02H7/26
Filed: 1990-01-15
Granted: 1995-08-01
Abstract: A directional comparison  relaying  system includes  forward  looking  pilot  relays  at  each terminal of a protected line segment and monitors which detect predetermined  incremental  changes  in line currents and voltages indicative of a fault. These predetermined incremental changes in current or voltage, which can be detected before the pilot relays  respond,  generate  local  blocking  signals which  are  transmitted  to  the  other  terminal  as remote    blocking    signals    over    a    two-way communications channel.   Trip signals for tripping circuit  breakers  at  the  associated  terminals  are generated from forward fault signals produced by the pilot  relays  but  are blocked by  the presence  of either a local or remote blocking signal.   However, the forward fault signal cancels the local blocking signal and the corresponding remote blocking signal at the other terminal so that when both pilot relays see an internal fault, the circuit breakers at the two terminals are tripped simultaneously.   Either a reverse direction distance relay or a reserve ground current relay and a zero sequence current monitor, generate a transient blocking signal which maintains the  local  blocking  signal  and  its  corresponding remote blocking signal at the other terminal,  and blocks a trip signal during transient fault clearing in other line segments to prevent overtripping.

Granted: 1994-09-27
Abstract: A jib stretching and folding device including an auxiliary connector mounted on a lower surface of a jib in the vicinity of a base end portion of the jib under the jib folded condition.  The auxiliary connector includes a cylindrical housing fixed to the lower surface of the jib and a connecting rod supported to the housing in such a manner as to be rotatable about the axis of the connecting rod substantially parallel to the lower surface of the jib and be movable along the axis of the connecting rod.  The jib is twisted about the axis of the connecting rod to effect a jib stretching or folding operation.  A twist guiding groove is formed on one of the housing and the connecting rod of the auxiliary connector, and an engagement projection is provided on the other of the housing and the connecting rod to engage the twist guiding groove.  When the jib is raised or lowered by a jib raising/lowering means, the engagement projection is moved in the twist guiding groove to generate a jib twisting force.          Thus, the jib is automatically twisted in the jib stretching or folding operation. Accordingly, a burden of labor of an operator in stretching and folding the jib can be reduced.          Further, the operation can be made continuous to thereby improve the efficiency of the jib stretching and folding operation.

Title: Method and apparatus for filing contours in digital typefaces
Inventor: MARTINEZ EDUARDO
IPC: G09G5/24
Filed: 1990-08-21
Granted: 2001-05-29
Abstract: A method and apparatus is described which fills in the pixels missed when drop-out occurs during the fill process of character contours. The character contour is decomposed into a series of rook moves.  The pixel selected is the one more covered by the actual shape of the portion of the curve where the rook moves are coincident and dropout occurs. This is dependent upon the slope of each of the curves at the location of dropout.  Preferably the length of the sequence of colinear consecutive rook moves is used to approximate the slopes of the curves. The target pixel of the longest sequence of colinear rook moves is more covered than its opposite pixel and therefore the target pixel is set.   The target pixel for a rook move is the pixel in the winding direction (i.e., left or right direction) along the rook move. Thus the target pixel of the stronger rook moves will be set and added to the bit map image generated using a outline fill process. In the preferred embodiment, the rook moves are examined to determine the length of a sequence, that is the number of rook moves that are sequentially in alignment with one another. A strength value is then assigned to each of those rook mopes in a sequence equal to the number of rook moves in the sequence. The strength value of the rook move is then compared to the strength value of the opposite pixel, that is the pixel opposite the target pixel for a particular rook move. If the strength value of the target pixel of the rook move is greater than the strength of the opposite pixel, the opposite pixel value is reset to zero and the target pixel is set to equal the strength of the sequence. This process is performed for each rook move in a sequence and for each sequence of rook moves around the contour of the character. Once all rook moves have been evaluated, the value is assigned to the pixels of the character according to this process, are adjusted to reflect a bit map image to be displayed. This is achieved by turning on all bits which are greater than zero. The bit map generated is then logically ORed with the bit map generated using the contour fill process to provide a filled character in which drop out is eliminated and the distortion to the character is minimized.

Title: Control of overload in communications networks
Inventor: FAREL RICHARD A
IPC: H04M3/36
Filed: 1990-08-30
Granted: 1993-09-14
Abstract: Abstract This invention relates to a method and apparatus for throttling request messages to an overloaded database and for throttling overload traffic to a particular destination. The database sends a gap value to the sources of messages or traffic; following any message or call to the destination, no messages will be sent or calls to the destination completed for one gap interval. In a departure from the prior art, the gap interval, a function of the number of request messages flushed or overload calls to the destination is not recurrently calculated anew, but is instead recurrently adjusted from its previous value. Advantageously, this arrangement permits a relatively stable value of the gap to be maintained and reduces overhead for preliminary processing of request messages that cannot be handled.
