Abstract: Logan-Reinhart-Sinclair 27-7-14 SEMICONDUCTOR RIB WAVEGUIDE OPTICAL    MODULATOR WITH HETROJUNCTION   CONTROL ELECTRODE CLADDING     Abstract of the Disclosure Formation of an optical modulator in an optical rib waveguide configuration in an epitaxial semiconductor layer is facilitated by using an electrode cladding (electrically conducting-optically transparent) layer for contacting the rib portion of the epitaxial layer.  The electrode cladding layer is essentially a polycrystalline compound semiconductive material of suitably low refractive index and is advantageously characterized by  a relatively high (0.4 to 1.0 volt or more) heterojunction potential barrier height at the epitaxial layer.  The electrode cladding layer results in relatively low optical waveguide cladding loss as well as good electrode contact, thereby facilitating the application of a modulating electric field into the epitaxial rib waveguide during operation.  The electrode cladding layer can also serve as a mask for con-trollably forming the rib portion with a predetermined rib height in the epitaxial layer.     - i -

The housing has a chamber which is connected to the dis-tribution mask and an opening which connects the chamber with the sur-rounding environment.  The anti-suffocation valve responds to an inhala-tion demand of a recipient to allow air from the surrounding environment to enter the chamber and satisfy the inhalation demand of a recipient to allow air from the surrounding environment to enter the chamber and satisfy the inhalation demand. A hydrophobic filter surrounds the opening and prevents the entry of any water present in the surrounding environment into the chamber which could inhibit cyclic inhalation of breathable fluid by the recipient.

Abstract: S P E C I F I C A T I O N                   IMPROVED APPARATUS FOR REPOSITIONING        BALES ON A BALE WAGON     ABSTRACT OF THE DISCLOSURE A bale wagon has improved apparatus for repositioning selected bales on its second, tier-forming table so as to provide a generally even stack side on the bale loader side of the bale wagon.  The apparatus includes a frame slidably mounted on the underside of the second table adjacent to the bale loader side thereof and a pair of bale engaging cleats mounted on the frame and extending upwardly through elongated slots formed in the second table.  The frame is slidable along a generally linear path which angles toward the forward right corner of the second table and is interconnected to a first, bale receiving table of the bale wagon through a cable and pulley system. A spring biases the slidable frame to an outer position toward the loader side of the second table.  When the first table pivots upwardly during delivery of bales to the second table, the cable pulls the frame to slidably move the same along its linear path to an inner position toward the longitudinal centerline of the second table which results in compression of the spring.  Oncethe bales have been deposited on the second table and the first table begins its descent back to its lower position, the cable slackens allowing the spring to pull the slidably frame back to its outer position during which the cleats on the frame engage and move an overlying bale along the angled linear path toward the loader side of the second table and away  from any other bales adjacent thereto.

Abstract: Abstract of the Disclosure The present invention relates to an easy open container end of the type that has a tab connected thereto by an integral rivet.  The invention resides in an improved method for forming a weakened area or frangible connection between a permanent section of a panel and a removable section. The frangible connection in the panel is formed in such a manner that the removable section is relieved of any compressive forces that may have developed during the formation of the frangible connection.   In addition, the removable section of the panel incorporates a further area of reduced cross-section that allows the tab and rivet to be pivoted relative to the removable panel section during initiation of rupture of the frangible connec-tion and provides a vent for the inside of the container prior to the rupture of the frangible connection.

Abstract: JOSEPHSON INTERFEROMETER STRUCTURE WHICH SUPPRESSES RESONANCES               Abstract of the Disclosure Josephson interferometers contain inductive, capacitive and resistive components, and, as a result, such devices are subject to the presence of relatively high amplitude resonances similar to those found in in-line gates.  Interferometer structures exhibit the same resonant behavior as long tunnel junctions, except that there exist only as many discrete resonance voltages as meshes in the interferometer device.          Hence, a two-junction interferometer has one resonance as compared to two resonances in a three-junction device.  In the I-V characteristic of a Josephson tunneling device such as an interferometer, such resonances appear as current steps which must be taken into account in the design of Josephson switching circuits primarily to avoid the situation where the load line of an external load intersects a resonance peak.  Where the load line and the resonance peak intersect, because such an intersection is stable, the device is prevented from switching to the full voltage desired.  Such resonances can be effectively suppressed in interferometers by providing a resistance which is in parallel with the main inductance of the interferometer.  In a two-junction interferometer, the resistance is effectively connected between the base electrode metallizations which are utilized to form one of the electrodes of each of the pair of electrodes required for each interferometer junction.  To the extent that more than two junctions are utilized, the resonance suppressing resistor is connected between pairs of junctions and across the main inductances which interconnect the junctions.  The structure of a two-junction interferometer with its resonance-suppressing resistor, RSR, is shown as well as the schematics of a multiple junction interferometer which clearly indicates how such structures may be fabricated.

Abstract: 25.8.77 ABSTRACT:         In a circuit arrangement for the digital correction of time base errors in a television signal this signal is converted into digital television sig-nals with a certain clock frequency in an analog/ digital converter, which signals are consecutively written into the individual addresses of a random access memory (RAM) with the same clock frequency and in the meantime are read from specific addres-ses of the memory with the game frequency. Which addresses are read depends on the magnitude and sign of the time base error, which is determined in a detection circuit from a comparison signal of the television signal and is converted into digital time base error signals which are quantized with a given time interval, which error signals are applied to all address signal which depending on the number of time intervals, which are defined by the clock frequency in the time base error signals relative to the number of addresses of the memory controls the selection of the addresses to be read.

Abstract: LORAN-C NAVIGATION APPARATUS                     Abstract LORAN-C navigation equipment is disclosed wherein digital circuitry is used to automatically distinguish a master LORAN-C trans-mitting station from a secondary station.  The equipment operator manually enters approximate time difference of signal arrival information for a par-ticular secondary station into the equipment after consulting a LORAN-C chart.  The operator then manually determines the exact time difference of arrival using thumbwheel switches and a LED lamp display.  This procedure is repeated to determine exact time difference of arrival information for the master and each selected secondary station, and the information is plotted in a well-known manner on the LORAN-C chart to locate the position of the craft upon which the equipment is located.  Manual acquisition of secondary stations simplifies the equipment and eliminates interference problems caused by skywaves and other transmissions.   The set oscillator is easily and quickly calibrated by the operator who manually enters the LORAN-C chain group repetition interval information found on the LORAN-C chart on the thumbwheel switches of the receiver and the adjusts the oscillator for a match as indicated on the LED display.
