Abstract: A NUCLEAR REACTOR OF THE               PRESSURIZED WATER TYPE     Abstract of the Disclosure In a pressurized water reactor, the pressure vessel contains a plurality of fuel wrappers of parallelepipedal section supported on a lower grid which carries projecting sleeves equal in number to the wrappers.  Each sleeve penetrates into a bore of a wrapper base plate and has a higher coefficient of thermal expansion than the base plate so that its external diameter is smaller than that of the bore in the cold state and equal thereto at the operating temperature of the reactor.  The bore is thus clamped against the sleeve as a result of thermal expansion, the fuel assemblies being secured within the wrappers by means of spring-type elastic devices.     US

Abstract: VELOCITY CHANGE SENSOR             ABSTRACT OF THE DISCLOSURE             A velocity change sensor adapted for mounting on a vehicle equipped with a passenger protective device, such as an inflatable air bag, comprises a body fitted with a normally open electrical switch connected to the passenger protective device's operating mechanism and adapted to be closed by a sensing mass upon movement of such sensing mass a predetermined distance in response to acceleration of the vehicle above a predetermined threshold.  The sensing mass is biased to a normally inactive, initial position under a force which establishes the acceleration threshold.  A biasing mass engages the sensing mass when the latter is in its initial position but moves out of engagement with the sensing mass in response to acceleration of the vehicle above the threshold level to permit movement of the sensing mass from its initial position toward its passenger protective device operating position.  Movement of the biasing mass is damped to prevent rebounding of the biasing mass and con-sequent interference with movement of the sensing mass.          Movement of the sensing mass also is damped to prevent operation of the passenger protective device except in those instances in which the acceleration and duration thereof are of such magnitude as to require operation of the pro-tective device.

Title: High density filter connector
Inventor: BOUTROS KAMAL S
IPC: H01R31/00
Filed: 1980-08-15
Granted: 1983-08-30
Abstract: ABSTRACT          The present invention relates to a multiple-contact connector for electrical circuits, of the type providing filtering of the indi-vidual circuits to suppress unwanted high frequency currents, and suitable for suppressing high values of current.  Filter connectors in the prior art have employed foil isolation planes, unsuitable for high currents, or have employed heavy ground plates in an expensive assembly requiring individual connection between each circuit and the ground plate.  Less expensive prior art connectors have employed encapsulation with conductive plastic to surround the filter elements and connect them to the shield, but have exhibited reduced shielding effectiveness due to the relatively high resistivity of the conductive plastic.  The present invention provides a connector having Improved shielding, in a low cost design.  Low cost and high performance are achieved by an encapsulated design which employs heavy end plates but does not require individual connection of the circuit element filters.

Abstract: Abstract of the Disclosure A method and apparatus for ink jet printing are disclosed which employ reverse charge coupling to increase character height.  A video signal is utilized to modulate the charge ring voltage.  Via a parallel path the ink in the nozzle is reversely charged by the video signal.  Thus, as the ink drops are formed their electrical charge is greater than can be ob-tained under ordinary circumstances.  This permits greater deflection of the drops resulting in larger characters on the printing media at the normal dis-tance between media and nozzle or higher quality characters of the same size if the media is moved closer to the nozzle.

Abstract: ABSTRACT                 A DIGITAL TIME-DELAY BEAMFORMER                    FOR SONAR SYSTEMS            There is described a digital sonar receiver having a novel beamformer, own doppler nullifier (O.D.N.), and adaptive time varied gain controller.  The beamformer interrogates a multi-element transducer by utilizing an interleaved sampling scheme which samples the elements in the transducer array sequentially, in such a fashion that continuous, uniformly spaced samples are obtained.  The samples are subsequently converted into digital format, weighed and summed.  The O.D.N. eliminates the own ship's doppler effect on the beam output signal resulting in a half beam output signal representative of the target doppler.          The O.D.N. offsets the frequency of the beam output signal and a digital generated signal representative of the own ship's doppler.  The O.D.N. multiplies these two offsetted signals resulting in a signal lying in each of the sum and difference frequency bands for which the signal lying in the difference frequency band corresponds to the target doppler.  The adaptive time varied gain controller varies the gain of preamplifiers at the input of the sonar receiver to be inversely proportional to the momentary average reverberation level of the medium in which the receiver operates.  The adaptive time varied gain control apparatus initially sets the gain of the preamplifiers to be inversely proportional to a standard reverberation curve during the first ping cycle and subsequently updates the gain of the preamplifiers during each successive ping-cycle by computing a gain correction from the average value of a pre-determined number of beam output signals.
