Abstract: A variable diameter rotor (3) for a flit rotor aircraft (1) has an inboard section (11) having a linear twist from a root end (12) to an outboard end (13) thereof; and an outboard section (14) telescoped over the inboard section (11) which additionally has a linear twist from a root end (17) to an outboard end (14) thereof. The outboard section (14) is disposed at an offset of about 4 to 15.degree. relative to the inboard section, (11) to provide a stepwise change in twist angle when in the extended condition, such that the rotor when operated in the helicopter mode, can be operated at high blade pitch angles without premature stalling along the in-board airfoil surfaces. This allows efficient operation at high thrust coefficient/solidarity ratios. Optionally, the trailing edge of the outboard section is rotated along the aft 34 % of chord of the airfoil section to provide an equivalent twist increase in the off-set at the transition between the blade sections. When in the forward flight cruise made, the inboard equivalent twist increment allows operation of the inboard airfoil sections at higher pitch angles to reduce negative lift regions and increase cruise propulsion efficiency.

Abstract: A method for the removal and recovery of paint overspray in a water wash spray booth is disclosed.  The method uses a circulating agitated dispersion of an organic solvent component in water which collects the paint overspray. The dispersion containing the overspray is permitted to phase separate into an organic phase and an aqueous phase. The organic phase is further treated such as by distillation to separate the paint solids from an organic solvent portion which contains the original organic solvent component and the organic solvents associated with the paint. The organic solvent portion can be recycled and reused in the circulating dispersion and the paint solids can be recovered for further use such as a filler for adhesives or can be disposed of.

Title: Field ground fault detector and field ground fault relay for detecting ground fault corresponding to dc component extracted from ground fault current
Inventor: TANAKA TOSHIO
IPC: H02H7/06
Filed: 1995-02-24
Granted: 2001-11-27
Abstract: According to a field ground fault detector, a predetermined resistor is connected in series to a predetermined DC voltage. A DC voltage is applied between an N electrode side field circuit of a generator and a ground through the resistor. A voltage applied between terminals of the resistor is input to a low-pass filter. A voltage applied between the N electrode side field circuit and the ground is input to another low-pass filter. Output voltages of the low-pass filters are input to a level ratio determining circuit.      The level ratio determining circuit outputs the determined result of the ground fault to the outside of the field ground fault detector corresponding to these voltages. Thus, even if the DC voltage varies or a higher harmonic voltage takes place in a generator of a thyristor exciting type, it does not affect the detecting sensitivity of the ground fault.

Abstract: A video traffic monitor and method for counting people using video imaging provides an inexpensive hardware implementation for analyzing real-time video where the operational environment presents a reasonably restricted traffic flow, such as in the entryway of a building. The video traffic monitor utilizes a windowed subsample of an image frame, and the image frame is further subdivided into gates. The video traffic monitor processes this windowed area to highlight the objects moving through the gates. The gates are then analyzed to determine a direction of movement for the people and support the logic for noise elimination and object discrimination. The video traffic monitor counts the detected people and records the count according to the direction of movement of the people.

Abstract: Apparatus and methods for reducing the risk of flashover during loadbreak operations of insulated separable connectors. In one aspect, the flashover distance for an electrical connector assembly is increased by supplementing exposed conductive portions of the male connector with insulated portions such that energized points on the energized connector are placed a greater distance away from the nearest ground plane on the complimentary connector. The additional insulation compensates for reductions in dielectric strength of the air occurring during separation of the male connector from the female connector. Also, the semi-conductive ground shield of the bushing is supplemented by an insulating sleeve. The insulative sleeve effectively removes a common ground plane to which an arc might tend during a flashover. In another aspect, a substantial airtight seal is prevented between elastomeric seals of the female connector and the probe of the male connector. The connection being thus vented, the available volume of air surrounding the energized components of the connector assembly is increased. In described embodiments, the probe portion of the elbow is configured to prevent substantial sealing between the connector components. An annular reduced diameter recess is located between the probe's metal rod and its arc follower and is elongated to prevent substantially airtight sealing between the elbow and bushing during the initial stages of the loadbreak operation itself. In alternative embodiments, the probe may be hollow and vented or include a groove disposed along its length.

Abstract: A low-cost monitor includes two comparators which are adapted to form a window comparator which frames a laser transmitter's normal range of operation. An apparatus for generating an amplified back-face-monitor voltage corresponding to the laser transmitter's optical output power level is coupled to the window comparator. A reference voltage is also coupled to the window comparator which defines the upper threshold of the normal operational range. A controllable variable voltage source is coupled to the window comparator and is used to define the lower threshold of the normal operating range, where this lower threshold has two associated threshold values as described above. The lower threshold is initialized to the first threshold value which corresponds to an end-of-life operating state of the laser transmitter. When the back-face-monitor voltage signal equals or drops below the first threshold value, an alarm signal is generated by the laser monitor, and the controllable variable voltage source is switched to a second state for providing a second threshold value which corresponds to failed operating state of the laser transmitter. As the optical output power level continues to decline with temperature and time, it eventually falls belows the second threshold and a second alarm is generated to indicate failure of the laser. A variable gain instrumentation amplifier is coupled to the generating apparatus and utilized to measure the optical output power of the laser transmitter.

Abstract: When illumination light is externally incident on a liquid crystal display, of the incident light, light of a polarized component in one direction passes through a polarizing film to reach a liquid crystal panel. After the light reaching the liquid crystal panel is optically rotated in accordance with the display pattern displayed on the liquid crystal panel, it reaches a polarizing film. The light passing through the polarizing film enters a holographic reflector. The incident light passes through a hologram without being diffracted due to the angle selectivity of the hologram. Light passing through the hologram is regularly reflected by a metal reflective layer arranged on the back surface of the hologram to be incident on the hologram again. Incident light (reflected light) is incident on the hologram at an incident angle having a plus or a minus sign reverse to the previous incident light. The incident light matches the angle selectivity of the hologram, and is transmitted aid diffracted at a specific angle to become diffracted light. The diffracted light passes through the polarizing film, the liquid crystal panel, and the polarizing film again to reach observer's eyes as pattern display light.
