Abstract: ABSTRACT OF THE DISCLOSURE     A preimpregnated material has a reinforcement substrate impregnated with a thermoset resin mix which includes an initiator susceptible to light in the visible range.          The material  has cover films in the conventional manner but at least one of them is opaque whereby to protect the material from premature hardening.  It gels and cures on exposure to ordinary daylight.  The material has wide applicability in patching or locally reinforcing, and in laying-up laminating processes.         A preferred mix has a polyester resin, or small amount of a thickener and a photoinitiator system comprising tribenzylamine, eosin and a benzoyl substituted-oxime carbonate ester.

Abstract: ABSTRACT A testing system is disclosed for telephone subscriber loops which are in part derived by multiplex facilities in what have come to be known as pair gain systems.  In this testing arrangement, the local drop wires from the remote terminal of the pair gain system to the subscriber are separated from the carrier system itself and tested by connecting them to a separate metallic pair extending from the central office to the remote terminal location.  Simultaneously, the carrier-derived portion of the subscriber loop is corrected to automatic testing apparatus which sequences through a plurality of automatic tests for not only transmission characteristics of the carrier-derived channel but also tests for the ability of the derived channel to transmit supervisory information such as ringing, coin control and party identification information.  The remote terminal of the pair gain channel is selectively terminated by a reflective or absorptive termination to assist in these testing procedures.  The testing system is designed 80 as to make carrier-derived channels appear to the central office testing personnel as if they were identical to metallic loops, thus saving considerable administrative burden in testing subscriber loops.

Abstract: ABSTRACT OF THE DISCLOSURE      A memory subsysem which couples to a multiword bus for processing memory requests received therefrom includes at least a pair of independently addressable dynamic memory module units.  Each memory unit includes a number of rows of random access memory (RAM) chips. The sub-system further includes an adder circuit, a pair of tri-state operated address register circuits and timing cir-cuits.  The address circuits include a pair of tri-state operated address registers which couple to the bus and to the set of address lines to each memory unit.  In response to a memory request, the registers store row and column address portions of a chip address of the memory request. A multibit adder circuit is connected to increment by one the low order row address when the least significant address bits of the memory request indicate a subboundary address condition thereby enabling access to a pair of sequential word locations.  Whenever a memory request specifies an address which cannot access a double word, boundary circuits upon detecting the condition cause the timing circuits to generate only timing signals necessary for accessing the first word location.

Abstract: TIME DIVISION SWITCHING SYSTEM            Abstract A multimodule time division switching system is disclosed in which intermodule calls are served by transmitting call information words over a bus system interconnecting all modules.  Each transmitted word contains information specifying the receiving module identification number, the time slot in which the call is to be served in the receiving module, as well as the message or intelligence representing the subject matter of the call.  A FIFO memory in each module is used as an input buffer to temporarily store each received word and thereby reduce the need for short term time slot synchronization between modules.

Abstract: Abstract of the Disclosure A hierarchical communication system has multipaths for different levels of the hierarchy, each set of paths is assigned a criticalness to the successful operation of the system.  Error races for all of the paths are monitored.  A threshold for defining an unusable data path is based upon the criticalness of the path to successful operation. That is, the more critical the path, the higher the error rate that will be sustained. A specific embodiment employs shift-registers for indicating the error rate of the last predetermined number of usages of the given paths.  A mass storage system employing the error-rate system is described.

Abstract: DIGITAL ROUGHNESS SENSOR            ABSTRACT           A closed loop engine roughness fuel control for an internal combustion engine operative to maintain the operation of the engine at a predetermined roughness level is disclosed herein.  The control measures two rotational intervals  within  each torque  impulse  imparted  to  the engine's  crankshaft  by  the  combustion  process  and generates a speed normalized engine roughness signal indi-cative  of  the  engine's  actual  roughness.   The  engine roughness signal is multiplied by the engine speed and summed with a reference signal to generate a bias signal operative to modify the quantity of fuel being delivered to the engine maintaining the operation of the engine at a predetermined roughness level.  A signal indicative of the first derivative of the engine speed is also summed with the reference and roughness signal to compensate for false roughness  signals  generated  during  transient  modes  of operation.  A start enrichment circuit, activated when the engine speed is below a predetermined speed, causes the roughness control to output a fixed bias signal indicative of the engine having a roughness level greater than the desired roughness level.  The fixed bias signal causes the fuel control computer to increase the quantity of fuel to the engine to enhance starting of the engine and until the engine reaches the predetermined speed.
