A valve member in the form of a sleeve is mounted on the body, in a first configuration the valve member being configured to allow fluid to flow through the port and in a second configuration the valve member being configured to close the port. The valve member is movable from the first configuration to the second configuration in response to a positive pressure differential between the bore and the tool exterior.

Abstract: An inlet venturi for coal-side exhauster fan structure used to deliver pulverized coal to a combustion chamber. Generally, the inlet venturi has an axial length comparable to that of the exhauster fan inlet, resulting in a shallow, smooth transition angle from the venturi to whizzer ring or similar structure for guiding the coal flow into the center of the fan assembly. The inlet venturi includes a back plate or collar portion which prevents eddy effects and pressure drop between the venturi throat and the exhauster fan inlet, and further serves to accurately position the venturi in the exhauster fan inlet. The inventive inlet venturi structure additionally permits the removal of some or all of the "whizzer" structure commonly used on such fans, resulting in substantial savings in power needed to drive the fan.

Abstract: This invention is an automatic capture and docking mechanism for a pair of spacecraft. A largely passive capture mechanism disposed on a first spacecraft includes a concave cone section with the narrower interior end to admit a ball of a predetermined diameter. When tripped, a capture device restricts the diameter of passage for capture of the ball. In the release position passage for the ball is unrestricted. The capture device is preferably reset by the other spacecraft to release the ball. A docking mechanism disposed on the second spacecraft includes a convex cone section constructed to mate with the concave cone section, ball at the end of a cable and a boom. The cable may be extended from or retracted to the apex of the convex cone section. A rotary drive coupled to the convex cone section permits relative rotation of the spacecraft. The boom may be extended from or retracted into the second spacecraft. The spacecraft dock by directing the extended ball into the cylinder, where it is captured.

Abstract: A video recorder, adapted for use in conjunction with a remotely controllable unit associated with television recording and/or viewing, contains a remote-control signal transmitter to transmit control codes to the associated unit, and means to analyze the operation of the associated unit in response to the control codes. An electronic controller causes the transmitter to transmit test codes to the associated unit, then analyzes the resulting operation of the associated unit to determine its control codes, which it stores in a memory for later use.

Abstract: A group of cabinets or other units each have a solenoid operated lock controlled by an electronic lock accessible by one or more electronic keys. The locks are linked together in a chain by power and data lines so that power is supplied through a single 12 volt transformer, and key codes are transmitted from a lock that reads a key to other locks, to open any cabinet programmed with an access code matching the transmitted key code. To limit power requirements, when one solenoid is being energized a busy signal is transmitted to prevent concurrent operation of other solenoids. A user installed master code stored in the lock and a corresponding master key are used to permit programming or erasing of other access key codes. A factory installed permanent reset code is stored in the lock and a secret algorithm known only to the manufacturer can derive the reset code from the cabinet serial number.

Abstract: A balancing station includes a vertical spindle having a collet for frictionally engaging the center hole of a wheel. A motor driven drum is mounted on an arm which is moved by an actuator to urge the drum against the wheel with a radial force so that it can frictionally drive the wheel. An idler drum or a second driven drum mounted on a similar arm on the opposite side of the wheel is moved by an actuator to engage the wheel at a location diametrically opposite the driven drum to apply a radial force to the wheel equal and opposite to the force from the driven drum. The arms are symmetrically mounted with respect to the spindle so that the two drums will contact diametrically opposite locations on the wheel for any size wheel over a large size range.

Abstract: An apparatus for draining a biological substance from a collection bag attached to a patient. The apparatus includes a large bore, thin walled drainage tube which expands to have a substantially circular cross-sectional configuration when a biological substance such as fecal material passes therethrough, and collapses into a substantially flat cross-sectional configuration when the tube is empty. A connector in the form of two adhesively coated, resilient, fluid impervious pieces of sheet material is used to connect the large bore drainage tube to the collection bag.

Abstract: A system for locating microwave radiation sources such as radar, jamming equipment and the like, employs a cannon launched shell including a frequency scanning receiver for the microwave emissions. Received information is processed on the shell and can derive signals that are used to modulate a telemetry transmitter. A ground base telemetry receiver associated with the launching cannon, includes means for processing the signals to derive the location of the microwave sources relative to the shell, and for processing information relating to the shell launch to determine its instantaneous position and attitude. The location of the sources relative to the launch site is then calculated and is used to aim the cannon and destroy the emission site.

Abstract: A method and apparatus for determining the edge of an individual frame of photographic film on a strip of photographic film being moved along a photographic film transport path. A plurality of light sensors are positioned in a substantially linear array substantially perpendicular to and on one side of the path and a light is shined through the film toward the array of light sensors as the strip passes along the path. By sensing the level of illumination incident upon each of the sensors and comparing the level of illumination incident thereon with a predetermined level corresponding to a known degree of opacity associated with the interframe border between individual frames on the film, the presence of a film edge can be determined when the level of illumination associated with a predetermined number of tile sensors corresponds to a degree of opacity at least as great as the predetermined level.

Abstract: Measurement of the fluorescence of a layer of cells, disposed in a well, with supernatant liquid thereabove, is greatly enhanced in sensitivity by illuminating the cell layer with a beam of light incident thereupon at a first angle and detecting fluorescence emitted by the cells with a detector which views the illuminated cells at a second angle, wherein at least one of the first or second angles is oblique to the cell layer. By so controlling the geometry of the system, the contribution to background fluorescence by the supernatant liquid is greatly minimized. Sensitivity of the technique is further enhanced by restricting the portion of the illuminated cell layer which is viewed by the detector. The technique may be applied to an apparatus for rapidly scanning the fluorescence of a plurality of samples in a multiple well plate.
