Title: Emergency venting cap and funnel assembly
Inventor: MYERS DONALD J
IPC: F16N31/00
Filed: 1990-09-13
Granted: 1993-04-13
Abstract: ABSTRACT         The invention relates to a combined funnel and cap member which can be attached to containers for receiving waste fluid such as fuel or lubricating oils. The cap member is pivotally attached to a funnel body and can be latched to the funnel body opposite the hinge mechanism. The hinge mechanism or the latch mechanism is constructed in such a manner as to permit the cap member to rise relative to the funnel body in the event of overpressures within the container so as to provide an emergency venting path for gases under pressure within the container. Once the overpressure condition has been relieved the cap member will return to its normally closed position under its own weight. The cap member can be unlatched from the funnel body and opened so that fluids may be introduced into the container therebelow.      .

Title: Gamma ray detecting device using crystal waveguides
Inventor: VALI VICTOR
IPC: G01T1/36
Filed: 1990-10-09
Granted: 1993-11-09
Abstract: GAMMA RAY DETECTING DEVICE  USING CRYSTAL WAVEGUIDES                                  ABSTRACT A .gamma.-ray telescope that comprises a dislocation-free single crystal. Typical crystals include silicon and germanium, for example. The crystal is surrounded by an active shield that functions as an anticoincidence counter and a .gamma.-ray detector is dis-posed adjacent the crystal in order to detect received .gamma.-rays. The .gamma.-ray detector com-prises an imaging proportional counter, scintillation counter, or a .gamma.-ray detecting charge coupled device, for example. The .gamma.-ray detector is based on the Borrmann ef-fect, which is the anomalous transmission of .gamma.-rays through dislocation free single crystals at the Bragg angle. For extended sources, data processing is provided to sep-arate the directional and wavelength dependence of the intensity variation. The .gamma.-ray telescope has angular resolution of at least one arc second and may have an effective aperture of several square meters. Reduction in background radiation, which is es-sentially determined by the crystal thickness, may be made quite large, greater than 1012. Consequently, the use of the present invention makes it possible to detect a weak .gamma.-ray source even in the presence of a large isotropic background.

Granted: 1997-07-15
Abstract: A  data  processing  system  is  responsive  to  a plurality of input languages, each language adhering to a prescribed syntax.   The presence of defined portions ("For" keys) in the incoming data indicate a vote  for  the presence  of  a  language  and  the presence of other defined portions ("Against" keys) indicate  a  vote  Against  the  presence  of  the language.  The system performs the following method for identifying the input language: analyzing,  for each expected language, the syntax of an incoming block of data to identify For and Against keys in the  block  of  data;   providing  For  and  Against tallies for each expected language in response to the analysis, each tally being a summation of key entries, each key entry comprising an identified key count multiplied by a skew, a skew value indicating the importance of the key in the syntax and in the context of said block of data, the For tally summing entries of For keys and the Against tally summing entries  of  Against  keys;  comparing  the  For  and Against tallies to determine whether or not they are so close as to signal uncertainty; and, based upon a further syntactical characteristic of block of data, resolving the uncertainty and indicating a value based on one of the tallies:  indicating a value derived from the larger of the tallies in the event of no uncertainty between the tallies; and deciding, based upon the indicated value for each  expected language, the identity of a received language.

Title: Surge current-limiting circuit for a large-capacitance load
Inventor: MCCAFFERTY LORY NEAL
IPC: H03K17/16
Filed: 1991-07-02
Granted: 1998-02-24
Abstract: A circuit for limiting switch-on surge current to a load including a large capacitance (12) includes a MOSFET (14) whose controlled path is connected in series with the capacitance across power supply terminals (+,-). A resistor (16) and a capacitor (20), having a relatively small capacitance, are connected in series with the controlled path, and a junction between the resistor and capacitor is connected to a gate of the MOSFET via a resistor (18) to provide a negative feedback path for charging the load capacitance with a constant current when power is applied. A capacitor (22) prevents initial turn-on of the MOSFET, and a zener diode (24) limits the gate voltage. Another arrangement uses a differential amplifier (50). The resistive part (10) of the load can be connected in parallel with the load capacitance, or to the power supply terminals for which it can be switched depending upon the gate voltage.

Title: Fully automatic energy efficient lighting control and method of making same
Inventor: ELWELL BRIAN E
IPC: H05B37/02
Filed: 1991-11-27
Granted: 2002-03-26
Abstract: A fully automatic and energy efficient lighting control or light switch (2, 150) comprises different settings, preset by a user, and activates all or a portion of at least one bank of lights (300, 320) upon detecting occupants within a room. In one embodi-ment, the light switch detects doppler-shifted, reflected ultrasonic waves caused by occupant motion within the room. In an auto-matic mode, the light switch (2, 150) is configured to automatically switch from an initial sensitivity level for detecting motion within a short range (260) therefrom, to a higher sensitivity level for detecting motion anywhere within the room. After the room is empty or no motion is sensed, the light switch (2, 150) is configured to turn the lights off following a variable time delay. The light switch (2, 150) returns to its initial low sensitivity level following a predetermined grace period which begins once the lights are turned off. The lights (300, 320) can be turned off manually when the light switch (2, 150) is in its automatic mode, in which case, the light switch (2, 150) continues to operate at the higher sensitivity level. When motion is no longer detected, and following the variable time delay and predetermined grace period, the switch (2, 150) automatically returns to an automatic "on" state. In an alternative manual mode, the light switch can be activated manually and deactivated both manually and automatically. In its manual mode, the light switch (2, 150) is configured to deactivate the lights (300, 320) upon sensing no motion and is configured to reactivate the lights automatically within the predetermined grace period upon sensing motion.

Filed: 1993-09-15
Granted: 1999-02-23
Abstract: A clamp circuit for use in a clock circuit having a phase-lock loop, the phase-lock loop including a phase detector, a loop filter, and a voltage-controlled oscillator, the clamping circuit connected between the loop filter and the voltage-controlled oscillator.  The clamping circuit selectively provides, under the control of a clamping signal either a path for the loop through the clamping circuit or clamping the input of the voltage-controlled oscillator to varying potential. The varying potential is provided by a resistor capacitor network. When the loop is closed the capacitor is charged to an average of the loop control voltage for the oscillator.  In response to the clamping signal the capacitor is connected to ground, thereby providing an RC time constant varying potential which allows the oscillator to be clamped to a fixed voltage in a slew-rate controlled manner.
