Abstract: Abstract of the Disclosure An extruded, low friction weather seal is disclosed which in transverse cross section consists of a semirigid base member of polypropylene, a tubular sealing member of thermoplastic elastomer, and a thin film of polypropylene or a blend of polypropylene and thermoplastic elastomer capping all or part of the tubu-lar sealing member.  The thermoplastic elastomer enables the tubular sealing member to be resilient and compliant over a wide range of temperatures, including extremely cold conditions, but has a high friction surface which is subject to wear particularly where there is relative sliding movement between the weather seal and surface to be sealed.  The polypropylene thin film cap provides a low friction contact surface without adversely affecting the resilience and compliance of the tubular sealing member.

Abstract: ABSTRACT OF THE DISCLOSURE A teleconferencing system for connection to telephone lines or other communication links. Directionally gated microphones receive local speech for audio send signal transmission to the far end on the telephone line, and audio receive signals from the far end are output locally via a loudspeaker. The outgoing send signals and incoming receive signals are automatically suppressed in accordance with user and setup controls (volume and suppression) and in accordance with the strength of the incoming receive signal. When the system is in a send mode, the receive signals are suppressed to a lower audible level; when the system is in a receive mode, the send signals are suppressed. The mode of the system is switched during conversation. When simultaneous talking (speech from both ends) occurs, priority is given to the interrupting party.

Abstract: ABSTRACT:          Integrated logic buffer circuit.     Integrated logic circuit comprising a pushpull amplifier stage, in which by means of a bootstrap circuit the potential at the gate of the "push" transistor is brought above the supply voltage so that the output voltage of the amplifier lies above the supply voltage minus the threshold voltage of the said transistor. In order to prevent the charge from leaking away after the bootstrap capacitance has been charged via an enhancement transistor, the enhancement transistor is cut off by means of the "low" input signal. A second bootstrap circuit (between the input and the gate of the enhancement transistor) ensures that the first bootstrap capacitance is charged up to the full supply voltage because the latter gate electrode is lifted above the supply voltage by the second bootstrap.

Abstract: ABSTRACT       This invention provides a specially shaped arc tube for a high-intensity arc discharge lamp, particularly a lamp for vertical operation.  The arc tube has a hemispherical top with radius R1, a hemispherical bottom with radius R2, and a middle section being a frustum of a right circular cone which on one end mates with the top and on the other end mates with the bottom so than the arc tube has a smooth and continuous surface.  R2 is greater than or equal to two millimeters.  The ratio R1/R2 is always greater than one, and in preferred embodiments R1/R2 is within the range of 1.5 to 3, inclusive.  This arc tube virtually eliminates species segregation in metal halide lamps even though the arc is vertical. The invention also includes an arc discharge lamp employing an arc tube as described herein together with an optimum choice of design parameters, such as wall loading and nitrogen pressure within the outer envelope.  The virtual elimination of species segregation of the additives along the arc axis provides this lamp with higher luminous output, lower color temperature, improved luminous efficacy, extended life, an no perceptible flicker with electrical current at fifty hertz compared with counterparts in the existing art.

Abstract: ABSTRACT OF THE DISCLOSURE      A clock buffer circuit for multiple phase complementary clocking signals that receives a plurality of corresponding enabling signals and generates a like plurality of clock signals in response thereto.  Each clocking signal is generated by a buffer module including a resistor, a pull-up transistor and a pull-down transistor, which are connected in series between a positive power supply and ground, with the clocking signal being taken from the node between the pull-up and pull-down transistors.  In each module, before the clocking signal shifts from a low state to a high, the pull-down transistor is on so that the clocking signal is at a low state.  The pull-up transistor in each module is controlled by the corresponding enabling signal and is enabled to begin conducting at the time that the clocking signal is to shift to a high state.  The resistor keeps the pull-up transistor in its linear, non-saturated operating regions, which results in an increase in the intrinsic capacitance in the pull-up transistor from the saturated condition.  After the pull-up transistor is turned on, allowing the intrinsic capacitance of the pull-up transistor to charge, the pull-down transistor is then turned off and the gate of the pull-up transistor is isolated.  The voltage levels at the gate and source terminals of the pull-up transistor rise in a bootstrapping operation.  When the clock signal is to shift to a low state, the complementary phase clocking signal turns on the pull-down transistor.
