Abstract: ABSTRACT OF THE DISCLOSURE     A phoneme-based speech synthesizer that is particularly adapted for implementation on a single integrated circuit chip.  The vocal tract is comprised of a fixed resonant filter and a plurality of tunable resonant filters whose resonant frequencies are con-trolled in accordance with the values of certain control parameters.  The vocal tract is implemented utilizing a capacitive switching technique which eliminates the need for large valued components to achieve the relatively low frequencies of human speech. In addition, a novel digital transition circuit is included which gradually transitions the values of the vocal tract control parameters as they change from phoneme to phoneme.  A unique glottal source generator is also disclosed which is adapted to digitally generate a glottal pulse signal in a manner which readily permits the glottal pulse to be spectrally shaped in any desired configuration.

Abstract: Abstract of the Disclosure An  improved  pendant  or  ceiling mounted  luminaire  having improved quick disconnect features is disclosed.   The luminaire is capable of being ceiling mounted and has a through-way electrical connection formed in a fixed housing which is mounted on the ceiling or suspended from the ceiling by an attached pipe. The top fixed housing contains a finger-safe female terminal block and a through-way means allowing building wire to be pulled straight through the housing.  A pivotable housing  is pivotably connected to the fixed housing and contains a mating male terminal block which is positioned within the housing. The fixed housing and the pivotable housing may be locked together by means of a locking latch so that upon release of the latch, the intermediate pivotable housing is capable of pivoting away from the fixed housing to electrically disconnect the  fixture  from the electrical  circuit.   The new and novel luminaire may be fused as desired adjacent to one or two of the male terminal corrections.

Abstract: ABSTRACT OF THE DISCLOSURE         Lengths of rail which are to be butt-welded together end to end are clamped in respective heads of a butt-welding machine.  Alignment of the rail lengths is checked by an alignment device.  Any adjustment necessary to achieve the required degree of alignment is made before welding.  The alignment device comprises suspended structure which forms a downwardly-opening bight.  The structure carries locating stops, clamping cylinders and electromechanical transducers with sensing plungers, all of which project into the bight.  To check alignment, the device is lowered until the ends of the rail lengths are received within the bight.  One of the rail lengths is clamped against the stops by the opposed clamping cylinders.  The location of the other rail length relative to the structure is sensed by the transducer and the machine clamps are adjusted until those transducers indicate alignment of the rails.
