Abstract: MONOBUS INTERFACE CIRCUIT USING OPTO-COUPLED HYBRIDS     Abstract of the Disclosure In order to reduce the signal loss in a telephone line switching and conferencing system there is interposed between each line and the switching matrix a monobus port circuit arranged to convert a transmitted telephone signal into an equivalent current source. An opto-coupled hybrid replaces the port circuit transformer and served to provide the desired voltage to current conversion. The currents from several monobus circuits are added in a bus resistor before distribution back to the individual monobus circuits as a voltage where the original signal is subtracted from the bus signal.  The resultant signal is transmitted to the telephone receiver via the opto-coupled hybrid. When the switching matrix crosspoint resistance is negligible, the component of the bus voltage measured at the current source output which results from current generated from each port circuit is equal and opposite in magnitude to the voltage generated in the port circuit. In any given line these voltages cancel each other, thereby eliminating the feedback signal.

Abstract: KEY CONTROLLED ADDRESS RELOCATION TRANSLATION SYSTEM            ABSTRACT    Translates each active address key (AAK) into a respective address-ability in physical main memory.  Each addressability comprises one or more physical blocks which may be scattered in the main memory.  Address keys are contained in plural key register sections, and AAK select circuits outgate to the translator each M K from a key register section corresponding to the access type for each storage access request currently received from a processor or I/O channel.    Each address key identifies a particular stack of one or more segmentation registers.  Each segmentation register can be assigned the address of any segment (i.e. a block of contiguous physical addresses located anywhere in the main memory).  Each segmentation register also has validity and read-only flag bits for its assigned block. Each stack can translate a contiguous set of logical program addres-ses into physical addresses.  Any stack can support all logical addresses apparent to a program, although the machine can cause a single program to access plural addressabilities due to the machine assignment of address keys.      For each storage access request for a logical program address, a stack is addressed by the AAK to determine an addressability.  Then a register in the stack is addressed by high-order bits in the logical program address.  The addressed register outputs the translated block address. The main memory can have any physical size in relation to the number of stacks, and to the number of segmentation registers in each stack.

Abstract: PISTON TYPE SEAL UNIT                  Abstract of the Disclosure A seal unit for movement through a flow conductor for pumpdown piston or well swab service, including a mandrel body, a seal element mounting sleeve disposed for limited travel on the body, and elastic annular seal means secured on the mounting sleeve to seal with the flow conductor wall in response to a first fluid differential across the unit and to permit controlled bypass and load transfer under a second higher differential.  The seal means includes spaced annular lips or fins and an annular choke ring which is expanded by limited sleeve movement in response to a fluid pressure differential load applied across the fins.  When the pressure differential across the fins exceeds a predetermined value, the sleeve expands the choke ring which assumes a major por-tion of the pressure differential load relieving the fins to reduce fin wear.  As a pumpdown piston, the unit is pumped along a flow conductor to drive a tool train by fluid flow in a direction from the fins toward the choke ring.  As a swab, the unit is pulled in the opposite direction to agitate or displace fluid in a well.
