Abstract: HIGH LEVEL SELF-CHECKING INTELLIGENT I/O CONTROLLER                 ABSTRACT OF THE INVENTION         The present invention is an input/output con-troller for providing total data integrity for any sin-gle point failure.  The I/O controller comprises a pro-cessor module having two microprocessors, an associated memory, a direct memory access module ("DMA"), and a processor support module ("PSM"); a device drive inter-face; and a channel interface.  The two microprocessors are operated in lockstep as a dual modular redundant processor system.  The processors provide true and com-plement, respectively, addresses, data and control strobes.  The PSM compares the true and complement data to detect errors (i.e., corresponding data bits not being a true-complement pair) and generates parity pro-tected data (and checks parity) on the data bus.  The PSM also generates and checks dual railed control strobes and provides synchronization of all control strobes and interrupt signals to enable the true-complement pair of microprocessors to operate in lockstep.  The DMA com-pares the redundant addresses from the processors to detect errors and to generate parity protected addresses (and check parity) on the address bus.  The DMA also generates and checks bus arbitration signals and con-trols direct memory access.  Self-checking checkers are used to check the various dual railed, true-complement pairs of signals to detect, locate and isolate internal faults.  Miscompares between true-complement address, data and control signals and parity errors detected in reading program instructions from memory all are -treated as fatal errors, which cause both processors to halt. Other types of errors are treated as nonfatal, which cause processor exceptions during which appropriate programming is executed to locate and isolate such errors.

Abstract: Abstract A method and apparatus for performing variable length data read transactions is presented in accordance with a preferred embodiment of the present invention.  An input/output (I/O) device which performs variable length data read transactions, such as one which includes a terminal, has associated with it a command linked list, located in system memory, in which a system processor or memory controller has placed command elements.  For read transactions, each element typically specifies the place in system memory where data will be transferred, and the number of bytes of data to be transferred.  The I/O device autonomously fetches elements on the linked list and executes them.  As bytes are being transferred from the I/O device to system memory a residual byte count is kept by the I/O device.  When the I/O device has completed the data transfer, it may interrupt or otherwise provide the system processor with status information as to the data transfer.  Additionally, the system processor may terminate a data transfer by sending a special flush command to the I/O device.  Upon receipt of the flush command, the I/O device stops the data transaction, and returns to the system processor the residual byte count.  The residual byte count is used by the system processor to determine how many bytes of information were transferred to system memory.

Abstract: ABSTRACT OF THE DISCLOSURE An  assembly   of   rotating ring  rotary  compressors comprising a cylinder defining a compression chamber,  a rotary  shaft  having  an eccentric  core  for  orbiting within  the  compression  chamber, a  rotating  ring  or roller  fitted around the eccentric core of  the  shaft, and first and second supports mounted on opposite  sides of  the cylinder for supporting the rotary shaft  in  a rotational  position within the cylinder itself.  Fixing means such as, for example, screws are provided  between the cylinder and the supports and allow the cylinder and the  supports  to  be clamped in  a  final  position  of assembly  of the compressor.  The cylinder,  the  shaft, the  roller  and the supports  are  initially  assembled together,  the  fixing means being kept in  a  slackened position.   A  preliminary centering operation  is  then carried  out for bringing the axis of the shaft  into  a diametral  plane   of   the   cylinder   constituting  a predetermined  reference   plane.    This  operation  is carried out by orientation of the shaft into two angular positions spaced from each other by 180°.  The shaft  is then  oriented relative to the cylinder, the  region  of maximum eccentricity of the core being brought into  the said  reference  plane.  The support  and  the  cylinder (this  latter with the interposition of the roller)  are then  pressed onto the shaft by a thrust exerted in  the said  predetermined plane.  They are thus  brought  into and  held  in a position of firm  mutual  contact:   the cylinder on the roller, the roller on the eccentric core of  the shaft and the support on the shaft at the  sides of the eccentric core.  The shaft and the support being kept  in the position of firm contact, the  cylinder  is then  given  a  relative  movement  of  a  predetermined magnitude  in the opposite direction from the  direction of  the force previously exerted. The magnitude of  this movement  identifies  the   minimum  aperture  which  is established,  in use, between the outer surface  of  the roller and the wall of the compression chamber.

Abstract: (005A/M4) "Offset-Compensated Switched-Capacitor Filter for TDM Multichannel Analog Signals"             ABSTRACT OF THE DISCLOSURE       For adaptive line equalization of a time-division multiplexed analog signal, an offset-compensated filter circuit comprises a timing circuit for generating channel-switching signals respectively synchronized with the time slots of the TDM signal.  A switched-capacitor filter comprising an operational amplifier and a switched-capacitor circuit is responsive to the channel-switching signals for sequentially establishing transfer functions specific to the time slots of the TDM signal.  A plurality of switched capacitor DC decoupling circuits are connected to the output of the switched-capacitor filter.  These DC decoupling circuits are respectively associated with the channel-switching signals for coupling a respective one of the filtered components to an input terminal of a summing amplifier.  Each of the DC decoupling circuits has a first and a second capacitor and switches responsive to the presence of the associated channel-switching signal for charging the first capacitor with a voltage developed at the output terminal of the switched capacitor filter and charging the second capacitor with a voltage developed between the output of the switched capacitor filter and the input terminal of the summing amplifier and discharging the first and second capacitors in response to the absence of the associated channel-switching signal.  The operational amplifier offset voltage and clock feedthrough of the switched-capacitor filter are eliminated.
