Abstract: This invention relates to a polyaromatic cyanate characterized by having the formula <IMG> wherein: Ar is an aromatic radical; B is a C7-20 polycyclic aliphatic radical; D is independently in each occurrence any nonactive hydrogen-containing substituent; q, r and s are independently in each occurrence the integers 0, 1, 2, or 3; with the proviso that the sum of q, 4 and s is greater than or equal to 2; t is independently in each occurrence an integer of between 0 and 4 inclusive; and x is a number between 0 and 5 inclusive; and the process for their preparation. The process is characterized by first preparing cyanogen chloride in situ in a chlorinated hydrocarbon solution. The aqueous layer containing the alkali metal chloride by-product is separated from the chlorinated hydrocarbon layer. Then the polyaromatic cyanate is prepared by contacting a bridged hydroxy -substituted polyaromatic compound with the cyanogen chloride solution. The polyaromatic cyanate compounds of this invention are useful in the preparation of polytriazine compounds which can be used as cure-in- -place resins or fabricated in the form of shaped articles. These polytriazines have good thermal stability, chemical inertness and solvent resistance.

Abstract: ABSTRACT OF THE DISCLOSURE      A flat cable system includes a flat cable of a first type which has equally spaced flat conductors in a body of insulating material.  A cable of a second type has three conductors, the centers of two of which are separated by the same spacing as in the cable of the first type but the third conductor is separated from the second by twice the spacing.  A cable of a third type has three conductors which are uniformly spaced by the same center-to-center spacing as in the first type.  When the cables are used together, the proper conductors are easily aligned for interconnec-tion by using a reference edge adjacent the first conductor in each cable.  The conductors are also color-coded.

Abstract: ABSTRACT: Amplifier arrangement.           A bias current (It) which is dependent on the input signal (Vi) is applied to the junction point (2) of the source electrodes of a first and a second transis-tor (T1, T2). The amplifier comprises a control circuit, which ensures that this bias current (It) cannot increase more than is necessary to obtain a high slew rate, thereby minimizing dissipation by the arrangement. This control circuit comprises a third and a fourth transistor (T3, T4) which are arranged in parallel with the first transistor (T1) and the second transistor (T2), respectively, and which carry currents (I3, I4) which are proportional to the currents (I1, I2) in the first and the second transis-tor (T1, T2). A selection circuit (5) applies the smaller of the two currents (I3, I4) in the third and the fourth transistor (T3, T4) to an output (8), where this current is compared with a reference current (I0) from a current source (9). The difference between these currents is applied to a current amplifier (10), which supplies an in-creasing bias current (It) until the smaller of the two currents (I3, I4) in the third and the fourth transistor (T3, T4) has become equal to the reference current (I0).

Abstract: Abstract of the Disclosure Until now, it has not yet been succeeded to prepare high performance carbon fibers having satisfactory strength from heavy oils of coal or petroleum origin.  We now succeeded to prepare an excellent intermediate pitch which allows the preparation of high performance carbon fibers having tensile strength of higher than 300 Kg/mm2 and Young's modulus of 50 ton/mm2.      The intermediate pitch can be obtained by heating a heavy oil of coal or petroleum origin in a tubular heater under a specific conditions, and then flash distilling the heater effluent in a flash distillation column under a specific condition so as to remove lighter fractions and recovering heavy fraction from the column bottom as the intermediate pitch.  The process for the preparation of the intermediate pitch is simple and economical and allows continuous production without fluctuation of quality of the intermediate pitch.  The intermediate pitch is also suitable for the production of higher density carbon products.

Abstract: Abstract An apparatus for counting occurrences of a plurality of events characterized by unique event numbers includes a random access memory for storing event count numbers at addresses corresponding to the event numbers.  The memory is addressed by an event number as the associated event occurs, and the event count number stored at such address is read and latched to an input of an adder.  The adder increments the latched event count number and the incremented event count number is then written back into the memory at the current event number address.  A buffer is provided to store the current event number whenever the adder overflows as a result of a count.  Several such event numbers may be stored in the buffer for subsequent retrieval by an external controller thereby permitting the con-troller to determine when an event has been counted a fixed number of times and to increment its own internally stored count at a slower rate than the rate at which data is applied to the prescaler.

Abstract: CIRCUIT BOARD ASSEMBLY FOR ACCURATE INSERTION            Abstract To provide accurate insertion of a circuit board into a high density socket in an equipment frame, a lever arrangement is mounted to the circuit board near its upper front edge on a pivot.  Rotational force applied to a first lever arm causes a second arm to engage the frame, translating the rotational force to insertion force acting at the pivot.  The combination of the acting insertion force and the insertion resisting force of the socket set up a moment couple.  The moment couple tends to rotate the circuit board, forcing a reference surface on the board against a mating reference surface on the socket during insertion.         The lever arrangement also provides mechanical advantage for extraction and, by using the resilience of the board, latching.  The lever also doubles as a faceplate to protect and beautify the equipment.
