Abstract: A load conductor for use with a circuit breaker includes a load terminal and a conductive tang engaged with one another. The load terminal is manufactured out of a first material having a first electrical conductivity, and the tang is manufactured out of a second material having a second electrical conductivity. The first electrical conductivity of the first material is such that the load terminal remains at a desirably high temperature during operation of the circuit breaker to avoid interference with the function of a bimetallic strip mounted on the load terminal. The tang extends across a bend formed in the load terminal to avoid the bend from becoming undesirably hot during operation of the circuit breaker. The tang also provides additional conductive cross-section and a higher conductivity surface to reduce the temperature of the load terminal in the vicinity of the clamped joint between the load terminal and the load. The abstract shall not be used for interpreting the scope of the claims.

Abstract: Multiple light emitting diodes (LEDs) capable of emitting light at different optical wavelengths are provided in a hand held device with switches for activating the LEDs separately or jointly. A matrix of radiant energy detectors are arrayed across a presentation screen at the display pixel locations of a screen. These radiant energy detectors are capable of distinguishing between the two radiant energy sources. A position location matrix is provided on the screen for detection where radiant energy is received from one or more of the radiant energy sources. Detection signal logic provides Boolean signals representative of which of the radiant energy signals is detected by the radiant energy detectors and control function logic responds to the position information and the Boolean signals to generate a cursor on a display screen and to manipulate display objects on the screen intercepted by the cursor.

Abstract: A cooled cooling air (CCA) system is provided for application with gas turbine cycles. In an embodiment of the invention, the CCA system includes a shell and tube heat exchanger in which water flow is provided inside the tube(s) and air flow is provided on the shell side. Water exiting the heat exchanger is partially evaporated. Accordingly, the resulting two phase water/steam flow is admitted to a separator where the steam and water are separated. The saturated steam is flowed to the HRSG whereas the separator water is recycled to the heat exchanger.

Abstract: A clear coat dicyandiamide cured epoxy powder coating for non-metallic substrates wherein the finish coat is visually haze-free as a result of the addition of a small amount of an aromatic substituted urea compound. Non-metallic substrates, such as brass, cannot withstand extremely high temperatures which are required to cure well known powder coatings. However, coating systems which cure at lower temperatures often produce a haze within the finish clear coat. The present invention alleviates this problem.

The system includes a circumferential electrically conductor ring which is coupled to, and insulated from, a tubular subsea element such as a tubing hanger, by an elastomeric electrically insulating sealing element, surrounding the conductor ring. The conductor ring is coupled to an electrical annular connector and is adapted to receive an electrical connector of a horizontally mounted electrical connector assembly which is hydraulically actuated to penetrate the elastomeric element in the direction transverse to the longitudinal axis of the tubular element to make electrical contact with the conductor ring.

Abstract: An electrical distribution system and method has storage battery mechanism of very large equivalent capacitance providing excellent ripple filtering and an ideal path to ground, and filter capacitor mechanism of microfarad size providing DC blocking and limited AC path to ground. The storage battery entity is maintained as to its charge by DC supply, which provides regulated DC power in which switching regulation may be involved. The system and method provides dual voltage capability, both DC and AC, in which circuit breakers may be ganged for simultaneous tripping, and in which intrinsic DC circuit(s) may be looped to increase current-carrying capability. A DC isolation capacitor is connected to a common current path, such as to one of the busses, such as, for example, in series with the neutral circuit, as a means for avoiding undesirable DC current paths as may be encountered due to a multitude of established neutral-line connections to earthing grounds established throughout in AC power supply network.

Abstract: Transient conditions, such as startup, shutdown, and contingencies, in gas turbine power plants are difficult to manage; oftentimes in designs employing a fuel moisturization system, such conditions require the use of backup fuel or a temporary fuel stream flare. The present invention enables the use of cold, dry fuel during startup and smoothly transitions to the use of moisturized, superheated fuel at high load without using a backup fuel. A bypass line allows fuel to enter a fuel superheater without passing through a fuel saturator. This enables the independent operation of the fuel superheater from the fuel saturator. Additionally, dry fuel is heated in the fuel superheater before moisturized fuel enters the fuel superheater. Gradually, a transition from dry fuel to moisturized fuel occurs before the gas turbine system operates at premixed combustion mode of operation.

Abstract: A diagnostic tool to assist patients in understanding the nature of medical conditions such as arthritis, includes a graphic display having a central scale with end points showing “REMISSION” and “WORST”. In addition, the tool comprises scales placed on either side and substantially equidistant from the central scale. One of the side scales is a patient assessment scale while the other scale is a clinical assessment scale. The side scales are arranged with end points adjacent the end points of the central scale. Lines may be drawn on the scale joining a patient's self assessment point with a clinical assessment done at the same time to demonstrate to the patient the patient's present condition, the therapeutic potential and the therapeutic opportunity.

Abstract: To provide auxiliary steam, a low pressure valve is opened in a combined cycle system to divert low pressure steam from the heat recovery steam generator to a header for supplying steam to a second combined cycle's steam turbine seals, sparging devices and cooling steam for the steam turbine if the steam turbine and gas turbine lie on a common shaft with the generator. Cooling steam is supplied the gas turbine in the combined cycle system from the high pressure steam turbine. Spent gas turbine cooling steam may augment the low pressure steam supplied to the header by opening a high pressure valve whereby high and low pressure steam flows are combined. An attemperator is used to reduce the temperature of the combined steam in response to auxiliary steam flows above a predetermined flow and a steam header temperature above a predetermined temperature.

Abstract: The invention provides a game apparatus which is in the nature of a vehicle or an attachment for a vehicle, the vehicle being operated by a driver, who travels with the vehicle. The idea is that the apparatus is equipped to receive from a play surface, hold and propel over the play surface a play member, in particular a ball. The apparatus can be described as a motorized version of football. The apparatus has an inlet by which the ball is received, and either the ball is propelled back out of the inlet or out of either of one or more separate outlets in the apparatus. When the ball enters the inlet it is held by a holding plate which rests, by gravity, on the top of the ball.
