Abstract: ABSTRACT        A safety handle for use with a load binder of the overcentre type having an operating lever comprises a tubular socket which is adapted to receive the operating lever and an extensible handle assembly connected to the socket by a universal pivot.  The handle assembly carries a projecting abutment plate which engages the socket when the handle assembly is retracted so as to restrict pivotal movement about the pivot and thus permit securing of the load.  When the load binder is released, any load transferred therefrom to the handle assembly upon movement of the operating lever past its overcentre position disengages the abutment plate from the socket and so permits the operating lever to move without the transfer of force to the user.

Abstract: UNITIZED SEAL BEARING ASSEMBLY          Abstract of the Disclosure A unitized sealed thrust bearing includes two annular races with a complement of bearing balls therebetween.  One race includes an axially inwardly extending central cylindrical flange and the other race includes a pair of elastomeric sealing lips, one bonded to the outer edge and one bonded to the inner edge.  The central flange includes an unobstructed radially inwardly facing wall and a radially outwardly facing wall with a radially and axially inwardly facing sealing surface terminating in a radially out-wardly extending rib.  The inner sealing lip includes an outer sealing wall which slopes axially and radially inwardly at a greater angle than the sealing surface, in its undeformed state, and an axially inwardly facing shoulder at the terminus thereof.  As the races are moved axially together during assembly, the sealing wall of the inner lip flexes as it slides past the rib and into engagement with the sealing surface, the shoulder moves adjacent the rib, and the outer sealing lip engages the other race.  Axial movement of the races apart engages the shoulder with the rib to compress the inner lip and retain the races.

Abstract: FAULT-TOLERANT COMPUTER  SYSTEM            ABSTRACT          A fault-tolerant computer system provides information transfers between the units of a computing module, including a processor unit and a memory unit and one or more peripheral control units, on a bus structure common to all the units.  Information-handling parts of the system, both in the bus structure and in each unit, can have a duplicate partner. Error detectors check the operation of the bus structure and of each system unit to provide information transfers only on fault-free bus conductors and between fault-free units.  The computer system can operate in this manner essentially without interruption in the event of faults by using only fault-free conductors and functional units.           Arbitration circuits of unusual speed and simplicity provide units of the computing module with access to the common bus structure according to the priority of each unit.           The units of a module check incoming and outgoing signals for errors, signal other module units of a detected error, and disable the unit from sending potentially erroneous information onto the bus structure.

Abstract: ABSTRACT OF THE INVENTION      A method and system for selecting and arming each one of a plurality of firing modules in a single-line selective perforating system is disclosed.  A single firing line con nects each firing module one at a time in a sequence to a control unit to receive power and control signals there-from.  Each module generates internally a module active time interval in response to being connected to the firing line power.  Each time interval has a first portion during which the module generates an identification pulse to the control unit to indicate that another module has been con-nected to the firing line, and a second portion during which the module is enabled to receive a selection pulse from the control unit to terminate further sequencing of the modules to locate the module to be selected.  The next module to receive power from the control unit is connected to the firing line by a pass-thru switch in the last con-nected module at the end of its active time interval if that module was not selected for firing.
