Granted: 1982-04-13
Abstract: Abstract of the Disclosure Breaks in heat seals between a paper member and a clear plastic member are detected by providing a paper member with a relatively dark coloration, for example dark blue, dark green or dark red, at least in the area of the heat seal, heat sealing the clear plastic member to the paper member in the desired seal. area whereby upon breaking the heat seal there is a distinct color contrast between the break in the heat seal and the relatively dark coloration of the paper and any remaining heat sealed area.  The method is especially suited for the manufacture of steril-izable packages or pooches for medical implements.  The paper member may have a portion which extends beyond the area to be enclosed by the heat seal when completed.  This portion bears indicia, generally printed on the paper, that changes color upon sterilization (either steam or gas sterilization).  The indicia herein, portion is adapted to be separated from the package and inserted therein together with any package contents before the heat seal is completed and the package contents are sterilized.

Abstract: TITLE:       PHOTOCOMPOSING MACHINE AND METHOD          INVENTOR:    LOUIS M. MOYROUD     ABSTRACT OF THE DISCLOSURE         The machine preferably has a character matrix comprising a rotating drum with character-bearing film strips wrapped around it.  The machine has a light source comprising a plurality of flash lamps and fiber-optic light pipes.  The light-pipes are arranged in a linear array aligned parallel to the direction of travel of the flim strips on the drum. Photographic film is formed into a semi-cylindrical arc and remains stationary during composition of up to a full newspaper page of text before the film is moved to another exposure position. Both character spacing and line spacing are performed by a combination of selective timing of the operation of the flash lamps, a lens and reflector traveling parallel to the film in a beam of collimated light, and a swinging mirror mounted on the axis of the semi-cylinder formed by the film.  Both timing slits and base-line reference marks are located on the film strips near each character.  The base-line reference marks are detected and used to make automatic corrections of the character image locations to ensure excellent base-alignment of the characters on the film.  Other corrections of the character image locations are stored in a memory and are made automatically during composition.  Several steps are taken to ensure accurate character spacing.  A separate, independent timing circuit is used to time the flashing of each character.  Also, the timing is determined by reference only to the timing slit immediately next to the character to be flashed.  Furthermore, timing delay is controlled by a clock pulse source whose frequency is controlled by the drum rotation so as to compensate for instantaneous variations in drum speed and/or position.  Each film strip bears coded indicia indicating the illumination level required for each different type face on the strip.  Automatic adjustments are made to compensate for the divergence     of the collimated light towards the end of very long lines of type composition. Special means are provided to compensate for the extension of italics and slanted characters to one side or the other of the normal character area.  Means also are provided for the insertion of "pi" characters and forming rules.

Abstract: * * ABSTRACT * *             MULTIPLE-STAGE HYDROCARBON CONVERSION WITH GRAVITY-FLOWING CATALYST PARTICLES              A multiple-stage catalytic conversion system in which a hydrocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones in each of which the catalyst particles are movable via gravity-flow.  The flow of the product effluent from at least one reaction zone is restricted.  This technique in-creases the pressure drop within the entire reactor cir-cuit, and serves to alleviate the problems associated with the occurrence of stagnant catalyst areas within the reaction zone which are unable to assume a downward gravity-flow pattern.  Flow restriction may be effected either be-fore, or after the inter-reaction zone heaters, preferably before.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention is directed to stable dispersions of copolymers in polyols containing added unsaturation. The polymer dispersions are prepared by reacting a polyol containing added ethylenic unsaturation and an ethyleni-cally unsaturated monomer or mixtures thereof in the presence of a free radical catalyst characterized in that the dispersion is prepared by the Williamson synthesis or a phase transfer catalyst modification thereof employing in situ polymerization of the ethylenically unsaturated monomer or mixtures thereof in the polymer containing added ethylenic unsaturation. The unsaturated polyols prepared by these methods may be used alone or they may be blended with polyols not containing added unsaturation. The dispersions are relatively low viscosity liquids which are useful in the preparation of polyurethanes such as, for example, foams and elastomers.   18,402-F

Abstract: Abstract of the Disclosure A single pair of conductors in a drill cable in a borehole is used not only to transmit power into the hole, but to transmit control commands into the hole, and to communicate sensor data back up to the surface.  A frequency for power and communication of 1 kHz is employed; but this is frequency modulated by deviation of about 5 percent to transmit commands down-hole.  A different non-interfering phase modulation is used to send data back to the surface by causing a susceptance (preferably capacitive) to be connected across the supply cable to signify a binary pulse.  The alteration in phase between current into the cable and potential across it is observed at the surface and the pulses so detected are processed by con-ventional data processing techniques.  A novel coding method is used for sending commands into the hole:  Each of a series of possible commands is assigned a binary value so that, for example, if commands #2 and #4 are to be sent, a total of 2 + 8 pulses (all of equal weight) forming a command word are sent down-hole where they are counted by a binary counter.  When the total number has been counted, outputs #2 and #4 of the counter 21 and 23 will have signals on them which constitute the transmitted orders.  This method is wasteful of time-bandwidth product (which is in abundant supply in this inventions's applications) but avoids problems of timing inherent is serial transmission of conventional binary signals.

Abstract: Abstract of the disclosure A stylus having an electrically-conductive writing tip is used to write on an electrically-sensitive paper, for example a metallized paper in which the metallization is eroded by the current passed by the stulus.   The stylus is energised by a coded train of electrical pulses whereby the coding is reproduced in the writing which can thus be verified as genuine.  The material to be written on, for example an airline ticket whose fraudulent alteration is to be exposed, may be supported on a stand having a conductive resilient arm bearing on the electrically sensitive surface to provide a return path for the stylus current.          The principle can be applied with coded optical pulses directed onto an optically-sensitive paper.

Granted: 1982-10-26
Abstract: ABSTRACT           Portions of an adaptive equalizer can be used for exact preamble synchronization by modifying the digital filter section to recognize pre-determined sequences of signals in the received signal.   This may be accomplished by applying to the modifying means of the digital filter input signals which are proportional to the complex conju-gate of the signals in the received signal.   When the signals in the tapped delay line are aligned with this complex conjugate, the output of the summing means will be discernibly greater than otherwise.  As a result, a thresh-old device can be used to recognize the exact baud time the preselected signals in the received signal are contained in the tapped delay line.
