Abstract: A vertical exterior weather seal for use in an adhesively glazed curtain wall system has opposing gasket members formed on either side of a central stem. The rear edge of the stem is received within a channel formed in the front wall of a frame member, and splines formed on the sides of the stem adjacent its rear edge engage the walls of the channel to retain the weather seal in place. A pair of curtain wall panels are butt-glazed to the front wall of the framing member on opposing sides of the weather seal, and the tubular gasket members on either side of the stem bear against the mutually facing lateral edges of the adjacent curtain wall panels to seal the joint between the panels. Because the weather seal requires only that a channel be provided on the front wall of the mullion, the seal is easily adapted to a wide variety of mullion configurations.

Abstract: A pulsed welding power supply with short circuit and overcurrent protection. A switching device (55) provides output voltage and output current to the output (17, 18, 19) of a pulse welding power supply. A welding parameter selection means (30, 32, 34, 37) provides a control signal to the switching device (55) which turns the switching device (55) on or off. A short circuit detector (72) monitors the output voltage and inhibits the control signal to the switching device (55) if the output voltage drops below a predetermined value. in order to allow the pulsed welding power supply to start operation, or restart after the short is removed, a resistor (45), connected in parallel with the switching device (55), access a limited current source means which provides a limited output current to the output when the switching device (55) is disabled.

Abstract: Agriculturally active materials, such as pesticides, herbicides and the like and a process for microencapsulating said material. The present invention includes trifluralin having a polymorphic form characterized by a yellow color and a melting point of approximately 41.degree.-43.degree. C. The present invention also includes a method using the yellow polymorphic form of trifluralin as a herbicide. In addition, the present invention includes a method of microencapsulating low-melting agriculturally active materials, such as trifluralin. The microencapsulation process comprises the steps of heating a low-melting, water-immiscible, agriculturally active material to a molten state. The molten active material is then combined with an aqueous solution of a water-soluble, film-forming polymer at a temperature sufficient to maintain the active material in its molten state.

Abstract: A DSP receiver for a fast turnaround modem, particularly suited for a half duplex fast turnaround modem which prevents destruction of communication channel related adaptive equalizer parameters upon loss of carrier. Upon detection of carrier loss, after sufficient time has been allowed for the last informational data bits to pass through the receiver's adaptive equalizer, the output of the equalizer's FIR filter delay line is looped back, via a multiplexer, to the input of the equalizer so that communications channel related samples are continuously provided to the equalizer to maintain the parameters at values based on the receiver's actual experience with data transmitted through the communications channel to which it is connected. A delay timer responsive to the loss of carrier signal will terminate updating of the adaptive equalizer parameters a predetermined time after loss of carrier. Alternately, detection of a standard end of data flag in the data stream will also terminate parameter update.

Abstract: Methods for avoiding a call blocking feature. In a first method a list is kept for the trunks previously used to call a particular telephone number. Each time that particular telephone number is called a different trunk, not on that list, is used to place the call. The list is cleared and restarted whenever all the trunks have been used. In a second method a list is kept for trunks for which a call blocking message has been received when an attempt was made to call that telephone number. Each time that particular telephone number is called a trunk which is not on that list is used to place the call. Only non-blocked trunks are used to call a telephone number.

Abstract: A carbon black reactor having an extended reaction choke substantially reduces the presence of coke and refractory grit in the carbon black product and erosion of the carbon black reactor due to impingement of particles of forming carbon black within the reactor. The carbon black reactor generally comprises a reaction choke which extends into an exit chamber to an outlet opening within the exit chamber. Hot gas and particles of forming carbon black flow through the reaction choke, through the outlet opening into the exit chamber. The outlet opening of the reaction choke is located within the exit chamber sufficiently distal from the upstream end of the exit chamber to substantially eliminate impingement of the particles of forming carbon black against the upsteam end of the exit chamber.
