Abstract: ABSTRACT OF THE DISCLOSURE           An improved connector assembly is provided for providing sealed and preferably sterile connection between a pair of conduits which each terminate in a hollow, trans-parent housing where some of the wall of each housing comprises a meltable wall portion sealed to the remainder of the housing.  The meltable wall portions of each housing are positioned in facing contact with each other and are held in sealed, retentive relationship so that exposure to radiant energy causes them to fuse and open an aperture therethrough.  The meltable wall portion extends across the hollow interior of the housing in a generally nonparallel direction relative to the axis of a passage which communicates the housing interior with the end portion of the conduit.

Abstract: TITLE A DUAL RAIL TIME AND CONTROL UNIT FOR A DUPLEX T-S-T-DIGITAL SWITCHING SYSTEM               ABSTRACT A duplex time-space-time switching network is shown in which there is a crossover of voice in-formation from one rail to another rail in a large digital switching system.  The time and control unit is divided into two rails both incoming and outgoing. Each rail multiplexes two 193 channel streams into one 386 channel stream of information.  These two rails crossover in the terminating time switching stage but remain segregated throughout the space switching stage.

Abstract: TITLE                 REFRACTORY RUNNER     ABSTRACT OF THE DISCLOSURE Molten pig iron flows from the hearth of a blast furnace down a runner positioned on the floor of a cast house and into ladles for receiving the iron.   The runner is constructed by a plurality of precast refractory side blocks and an interconnecting base of compacted particulate refractory material to form a substantially U-shaped trough extending a preselected distance and along a preselected path from the hearth to one or more ladles for conveying the iron from the blast furnace.   The trough has opposed, upstanding side walls and a floor extending between the bottom of the side walls.   The side walls are formed by individual side blocks positioned in abutting end to end relation on the cast house floor.  The compacted base forming the trough floor extends between and interconnects with the side blocks.   The adjacent ends of the side blocks are notched to form a joint for receiving castable refractory material which, upon setting, interlocks the ends of the adjacent side blocks.   The side blocks are selectively positioned relative to one another to extend the path of the runner in a preselected direction and to connect branch runners with the main runner. In the event a portion of the side wall or floor of the trough becomes worn, a replacement side block is inserted and additional particulate refractory material compacted into position.  The trough can be covered by positioning individual refractory cover blocks in end to end relation on the upper edges of the side blocks to span the trough above the floor.

Abstract: DIGITALLY CONTROLLED TRANSVERSAL EQUALIZER                 ABSTRACT OF THE DISCLOSURE An adaptive  equalizer performs equalization at IF,  demodulates the input signal and then generates the  equalization coefficients  at baseband from the demodulated data.  Coefficient updating can be done on a non-real time basis and coefficients for individual bursts stored in a coefficient memory for retrieval when the same burst occurs in the next frame, thus obtaining a pseudo-continuous  equalization for each burst.  In one embodiment, the error signal is derived from demodulated equalized data and correlated with demodulated unequalized data to generate the correla-tion coefficients, and individual error signals from each channel can be combined into a single composite error signal for correlation purposes.
