Abstract: ABSTRACT OF THE DISCLOSURE A PCM regenerated comprises an input transformer, amplitude and time decision devices and a pulse amplifier and shaper coupled in series with one another with a phase discriminator and a timing signal generator forming a phase-locked loop and the generator timing signal being applied to the time decision device.  To facilitate the processing of high bit rates each of the amplitude decision device, the time decision device, and the phase discriminator comprises two separate signal paths, one for positive and the other for negative input signals.  These regenerators are used in transmission paths for PCM signals for the amplitude and time-wise regeneration of transmitted time multiplex signals.

Abstract: ABSTRACT OF THE DISCLOSURE:     A gas stream containing nitrogen oxides, such as the tail gas from a nitric acid plant, is treated to reduce the nitrogen oxides content thereof.  In a series of liquid gas contact zones, the gas stream is first scrubbed with an aqueous solution of ammonium nitrate at a pH of about 0.1 to about 5.0; subse-quently scrubbed with an aqueous solution of ammonium nitrate at a pH of about 7.5 to about 8.5; and thereafter scrubbed with water.  The resulting scrubbed gas stream of reduced nitrogen oxides content may be safely discharged to the atomsphere without causing air pollution, the nitrogen oxides content being below imposed standards.  The apparatus useful for carrying out the above method includes in combination a plurality of packed gas-liquid contact zones, serially arranged, with the first of the contact zones having an inlet for the introduc-tion of a gas stream rich in the component to be removed, e.g., nitrogen oxides and the last of the contact zones having an outlet for the withdrawal of a gas stream lean in such gaseous component, each of the plurality of contact zones including an inlet for the introduction of a scrubb-ing liquid and an outlet for the withdrawal of spent scrubbing liquid and gas, the scrubbing liquid and gas in each contact zone passing concurrently therethrough; and separator means associated with each of the plurality of contact zones adjacent the outlet thereof to separate spent scrubbing liquid from the gas stream, the gas stream then being forwarded from each contact zone to the next succeed-ing contact zone.

Abstract: ABSTRACT OF THE DISCLOSURE            A cassette loading mechanism for use in conjunction with a tape transport apparatus in which the take-up and supply reels are simultaneously driven by surface engagement of a capstan with the outermost tape layer on each reel. The loading mechanism enables a hinged protective cassette containing a supply reel to be easily loaded into the tape transport apparatus and made ready for threading with only three simple actions to be performed by the operator. First, depending on the particular embodiment, the cassette is loaded into either a cassette tray or into a pocket in a hinged door directly over the take-off shaft. Second, pushing down, either on the cassette itself or on the hinged door, accomplishes the simultaneous snapping of the hub within the cassette onto the supply shaft and the releasing of the locks holding the cassette closed. Finally, the sliding of a single knob opens the cassette and advances the supply tape pack until brought into contact with the driving capstan. Removal of the cassette with the tape therein after use is accomplished by the reversal of the above operations.

Abstract: SIMPLIFIED CAB SIGNAL RECEIVER CIRCUIT              ABSTRACT OF THE DISCLOSURE    This invention covers train cab signal equipment for re-ceiving frequency modulated rail code signals which, when de-coded, provide a zone speed control signal which the railway train traversing the track rail must obey in order to proceed at a safe speed.  The invention includes a signal limiter cir-cuit which prevents the signal supplied to the several code frequency responsive networks in the decoder unit from exceed-ing a predetermined maximum value in order to assure a well-defined frequency bandwidth to which respective code filters in the frequency responsive networks are sensitive, so that only a single network is responsive to any given code signal.          In addition, the limiter circuit supplies the respective fre-quency responsive networks with a code signal whose amplitude is proportional to rail current so long as the code signal is below the maximum level set by the limiter.  This permits a level detector associated with each code filter to monitor the code signal received for minimum level detection in order to assure that the rail current code signal is a valid code signal.

Abstract: LINE PROTECTION SWITCHING SYSTEM            Abstract of the Disclosure Protection for service lines linking offices in a communications sytem is realized by linking the offices in a sequence with a serial connection of pro-tection lines.  Protection for service lines which by-pass one or more of the offices in the serial sequence is achieved by automatically controllably cascading appropriate ones of the protection lines.  The cascading of protection lines is realized on a nonhierarchical basis by assigning each service line in the system a unique address and by supplying a protection switch request message including the address of the requesting service line sequentially to each office in the serial sequence until the transmit-end of the requesting line is  located.  A switch-is automatically effected by equipment located at the offices only if all the pro-tection lines to be cascaded are available.  The availability of the protection lines is indicated at each office and an indication thereof is included in the protection switch request message being propagated sequentially to the offices in the system.

Abstract: PROGRAMMABLE CONTROLLER                   Abstract of the Disclosure A programmable system controller stores in memory a sequence of program words directly simulating a planar ladder diagram characterizing the desired operation of a con-trolled system.  The ladder diagram is a set of  n  rung-by-m column arrays of contacts interconnected with particular controlled devices of the system.  The program words are read out of the memory in a sequence to directly represent the ladder diagram on a rung-by-rung basis for each column.  The controller includes an interface unit coupled to a set of input switches for providing switch signals that are indicative of the operating status of the machine.  A data processing unit is provided with an accumulator having a plurality of at least  n  storage units respectively corresponding to each rung of the ladder diagram.  In response to the program words and to the switch signals, the accumulator sequentially determines the states of the storage units according to whether the switch signals are indicative that a particular rung of one column of the ladder diagram can contribute towards operating the controlled device as it is connected in the ladder diagram.  After the plurality of storage units have been conditioned according to the rungs in one column, the next column of the ladder diagram is considered for conditioning the storage units.          After all columns of the ladder diagram have been considered, a preselected one of the plurality of storage units contains an output signal indicative of whether the controlled device should be operated.   1.
