Abstract: COUNTER APPARATUS                Abstract of the Disclosure Apparatus for measuring the radioactivity of the contents of a plurality of receptacles supported in a rotatable ring.  A first group of a selected number of the receptacles is aligned,by the incremental rotation of the rotatable ring, above a like number of probes for re-ceiving the receptacles and for measuring the radioactivity of the contents thereof.  Upon this alignment, the rota-tional movement of the ring stops and the ring is vertically lowered a selected distance so that the selected number of receptacles are received in the probes.  After a time interval sufficient for the measurement of the radioactivity of the contents of the selected number of receptacles by the probes, the ring is vertically raised to its original position thereby removing the receptacles from the probes.          The ring is then rotated another incremental distance to bring a second group of the selected number of receptacles into alignment above the probes and the cycle is repeated.          This cycle is continued until the radioactivity of the contents of all the receptacles supported in the rotatable ring is measured.     S P E C I F I C A T I O N

Abstract: Abstract of the Disclosure The present invention relates to an additional concentrator for use in a Traffic Service Position System (TSPS) to facilitate the handling of operator assistance telephone calls requiring routing back to originating offices.  More specifically, on the toll office side of this additional concentrator in addition to the normal TSPS remote toll trunks, "loopback" trunks are provided for establishing connections through this concentrator directly back to a plurality of "local" offices served by the concentrator.  Operator assistance calls in which only a single digit (normally 0) is dialed are connected to these loopback trunks with the expectation that the call will be completed back to the originating or associated office.  If, however, the calling party later indicates to the operator that the call is actually destined for a telephone station accessible through the toll office, then the original concentrator connection is broken-down and a new connection is established between the calling station and one of the TSPS remote toll trunks.

Abstract: ABSTRACT OF THE DISCLOSURE      A shoring or scaffold for construction, maintenance and other work, using stacked scaffold sections of a demountable type and having a heighth adjusting construction is provided. Each section has a pair of spaced-apart end frames that are demountably cross-connected with respect to each other and the end frames of upper and lower sections have a telescopic adjustable relation to meet heighth requirements.  To provide strength and support rigidity, dual-tire bracing members are utilized to extend from the end frame of a lower section across and in an interconnecting relation with an opposed and frame of an upper section.  A simple adjustment of the bracing members in conformance with vertical adjustments made between upper and lower sections is accomplished by utilizing members that at one  end have a gooser pivot mounting on a horizontally extending connecting member of a frame of one section and that at the other end have a latching arm which is provided with a group of spaced-apart latching hole portions whose spacing is proportioned to vertical adjustment positions between the upper and lower sections.  The latching hole portions are adapted to selectively detachably latch with a single latching pin means which is carried in a protected relation on an inwardly offset, short length or secondary leg member of the opposed frame of the other section.  This enables the use of a single brace member for different heighth adjustments of stacked sections.

Abstract: ABSTRACT OF THE DISCLOSURE          A two phase sprayer and process are disclosed in which the sprayer has a liquid supply tube surrounded by a coaxial gas or gas mixture supply tube which extends beyond the length of the liquid supply tube where the gas flow sur-rounds and atomizes the expelled liquid. The sprayer has a unique structure in part characterized by a narrowed taper gas supply tube which converges towards the outlet at an angle of 70-90° with respect to the sprayer axis. The inter-nally-positioned, coaxial liquid supply tube is chamfered also at a similar 70-90° angle, the gas and liquid tubes at their outlet being essentially parallel.           The joint of the narrowing part of the gas tube and the outflow channel is rounded.           These sprayers efficiently spray relatively large amounts of liquid at low gas velocities and are particularly adapted for spraying a mixture of urea and ammonia into a bed of reactive, fluidized particles to form melamine without destroying desirable features of the fluidized bed into which the urea/ammonia mixture is sprayed.

Abstract: ABSTRACT OF THE DISCLOSURE           A control system for controlling a process having at least one significant parameter has a primary control loop responsive to the rate of change of the magnitude of the parameter and a secondary cascaded control loop responsive to the magnitude of the parameter representing a time integral of the rate of change of the magnitude of the parameter.  In prior art systems which are responsive to rate of change and to magnitude of a parameter, it is usual to have a primary control loop responsive to the magnitude of the parameter and a secondary control loop which imposes some secondary limitations on the rate at which the magnitude can change.  Such prior art systems suffer two disadvantages.  Firstly, due to interaction between the primary and secondary loops, the procedure for ad-justing the controller gains to achieve optimum or near optimum control of the individual loops as well as of the two loops acting in concert typically involves a successive approximations approach, and so can be relatively cumbersome and difficult.  Secondly, automatic gain control may not be easily applied.  However in the control system according to the invention, the primary control is of the rate of change of the magnitude of the parameter and this may control the magnitude of the parameter for example as a time integral of the rate of change.  This facilitates obtaining optimum or near optimum stability and regulation in the control of the rate of change of the magnitude of the parameter as well as in the control of the parameter itself; it also permits automatic gain control to be easily applied.

Abstract: TERNARY LOGIC CIRCUITS WITH CMOS INTEGRATED CIRCUITS            Abstract of the Disclosure:           Ternary storage elements are realized using ternary operators and fundamental circuits, designed to make practical use of CMOS (or COS/MOS) integrated circuits.  Word-organized and trit-organized memory cells are designed for the construction of a ternary random-access-memory array (TRAM).  Several flip-flops (tri-flops) are constructed and described in detail, including a PZN (set positive, set zero and set negative), a clocked PZN, a D-type and a T-type.  Ternary shift registers and ring counters are formed by means of these tri-flops.  A master-slave T-type tri-flop is used for the construction of a ternary up counter which is able to count from 0 to 3n using the normal ternary code or from -(3n-1)/2 to +(3n-1)/2 when the signed-ternary code is employed.  With a little modification, a ternary down counter may also be constructed.  A divide-by-M ternary counter which can be programmed is described.  A ternary decoder and encoder are presented, which are the elements of a complete ternary read-only-memory (TROM).  A modified ternary inverter (MTI) is taken as a unit cell of a ternary memory matrix.

Abstract: Abstract Of The Disclosure A jet drop printing head comprises a transportable upper assembly and a lower assembly adapted for receiving the upper assembly in such a manner as to control the alignment between the two assemblies.  The upper assembly, which is primarily a fluidics package, carries an orifice plate and fluidic elements for producing a jet-forming flow of printing liquid through a series of orifices in the orifice plate.  The upper assembly also carries a set of three rests which have been prealigned for mating engagement with a set of precision machine balls mounted in a charge ring plate carried by the lower assembly. Upon assembly the three rests are readily received by the three balls, and the orifice plate orifices are brought into precise registration with corresponding apertures in the charge ring plate.  In this arrangement the charge plate assembly, including the three balls, functions as a reference subassembly, and once an upper assembly has bad its three rests adjusted for alignment with any charge plate assembly, then the upper assembly may be mated with any lower assembly carrying a similar charge plate and ball arrangement.  A novel catcher mounting assembly permits ready operational positioning of a pair of catchers and easy downward swinging for inspection of the orifice plate.  There is also a fluidics system which minimizes accumulation of coagulated ink and includes a double diaphragm having a valving diaphragm which works against the raised lip of a conduit insert and a control diaphragm which works against a valve closing spring.

Abstract: A MARKOV PROCESSOR FOR CONTEXT ENCODING           FROM GIVEN CHARACTERS AND FOR CHARACTER                DECODING FROM GIVEN CONTEXTS                  Abstract In an apparatus for generating variable length codewords c(ai) and c(aj) responsive to corresponding fixed length codewords b(ai) and b(aj), where ai and aj are source alphabet characters, ai.epsilon.A1 and aj.epsilon.A2,ambiguity arises whenever any fixed length charac-ter to be encoded can instantaneously represent source characters ai and aj drawn from two or more dissimilar alphabets i.e., A1 or A2.  This is resolved by the inclusion of a Markov processor in com-bination with the apparatus.  The processor establishes the point in the sequence when transitions occur between fixed length char-acters in one alphabet to fixed length characters in another alpha-bet by the message context.  The processor includes a map of state and transition paths.  This map models certain statistical regulari-ties of runs of fixed code elements and the relative likelihood that an ambiguous fixed code character appearing in a first run belongs to a given alphabet.  The processor, starting from an arbitrary initial position, tracks any given run of fixed code characters applied to the encoder in terms of a succession of states and paths.
