Title: Signaling cell switching system
Inventor: MURAYAMA MASAMI
IPC: H04L12/70
Filed: 1991-02-07
Abstract: Abstract of the Disclosure An index value output circuit outputs an index value in response to a VCI added to the first signaling cell outputted from a terminal unit.     A switching data output circuit outputs switching data for determining a path for signaling cells, based on the index value.    Hence, by revising the index value according to a congestion state of an ATM switch, the above path is dynamically changed.     The same index value is inserted in the second and subsequent signaling cells outputted from the terminal unit.          Because switching data are based on the same index value, all signaling cells from the same terminal units are fed to the same signaling terminator.

Abstract: Tool for slitting and laterally expanding underground steel gas mains and inserting replacement plastic piping into the spread apart pipeline has a forward end cylindrical portion mounting a single, rearwardly angled blade to make only one line of cut, and a conical pipe spreader portion at its rearward end. The conical spreader portion is eccentrically disposed with respect to the forward end cylindrical portion. A single roller type pipe slitter aligned with the fixed blade may be mounted on a removable extension of the forward end cylindrical portion, to initially groove and weaken the pipe along the intended line of cut. A pneumatically operated impact ram is attached to the rearward end of the tool, as is the leading end of the replacement piping. A wire cable pulls the tool through the underground pipe, thereby grooving, slitting and laterally expanding the pipe. The spacing of the roller slitter in advance of the fixed knife blade is dimensionally related to the length of any coupling or clamp as may be anticipated along the line of cut, and the spacing distance of the fixed knife blade forwardly of the conical spreader portion is related to the cone angle of the latter to increase hoop tension immediately in front of the fixed blade as the cutting proceeds.

Filed: 1991-03-21
Abstract: A dispensing gun for viscous materials comprises a stock (12) supporting a push rod (28) which is advanceable along a keep (13) in which is mounted a cartridge of the material. The rod is advanced by means of a catch plate (41) and trigger (43) arrangement which bites on the rod and is retreated by a return spring (42). A release plate (51) prevents the rod retreating with the catch plate. The release plate is frictionally engaged with the rod so that it acts as a lost motion brake once force is removed from the trigger. In this way the rod is allowed a limited retreat to take the dispensing force off the cartridge to prevent leakage when the trigger is not depressed. <IMAGE>

Title: Method and apparatus for cleaning contaminated particulate material
Inventor: LAHODA EDWARD J
IPC: A62D3/00
Filed: 1991-05-02
Abstract: Abstract of the Disclosure Particulate  material  such  as  for  example  soil contaminated  with  heavy  metals,  radioactive  species  and organics,  singly or  in  combination,  is  treated by first washing  the  contaminated  material  with  a  contaminant mobilizing   solution comprising  a   leaching   agent,   a surfactant or a mixture thereof.  Large particles, typically greater than 5 mm are mechanically separated, washed with water and returned to the site as recovered soil.   Fines, along  with  contaminants  dissolved  or  dispersed  in  the contaminant   mobilizing   solution   are  separated   from intermediate sized particles by a countercurrent flow of the contaminant mobilizing  solution,  preferably  in a mineral jig.   The intermediate sized particles are then abraded in an attrition scrubber to dislodge attached mineral slimes or fines.    These  additional  fines  are  separated  from  the intermediate sized particles with a countercurrent flow of wash water in a second mineral jig.  For some applications, the intermediate sized particles can also be abraded in an attrition scrubber prior to size separation in the first mineral jig.  The slurry of intermediate sized particles and wash  water  discharged  from  the  second  mineral  jig  is dewatered  to  produce  additional  recovered soil.   If  the contamination includes insoluble heavy metal particles, they are separated from the effluent discharged from the second mineral  jig by density separation preferably in a cross-current flow jig, prior to dewatering. Various techniques can be  used  to separate  the  fines  and  the  contaminants dissolved and dispersed in the waste slurries discharged by the  two  mineral jigs  used  for  countercurrent  flow  size separation from the contaminant mobilizing solution which is recycled.

Title: Mask processing unit for high-performance processor
Inventor: BOUCHARD GREGG
IPC: G06F12/08
Filed: 1991-06-28
Abstract: MASK PROCESSING UNIT FOR HIGH-PERFORMANCE PROCESSOR          ABSTRACT OF THE DISCLOSURE    A pipelined CPU executing instructions of variable length, and referencing memory using various data widths. Macroinstruction pipelining is employed (instead of microinstruction pipelining), with queueing between units of the CPU to allow flexibility in instruction execution times.  A wide bandwidth is available for memory access; fetching 64-bit data blocks on each cycle.  A hierarchical cache arrangement has an improved method of cache set selection, increasing the likelihood of a cache hit.  A writeback cache is used (instead of writethrough) and writeback is allowed to proceed even though other accesses are suppressed due to queues being full.  A branch prediction method employs a branch history table which records the taken vs. not-taken history of branch opcodes recently used, and uses an empirical algorithm to predict which way the next occurrence of this branch will go, based upon the history table.  A floating point processor function is integrated on-chip, with enhanced speed due to a bypass technique; a trial mini-rounding is done on low-order bits of the result, and if correct, the last stage of the floating point processor can be bypassed, saving one cycle of latency.  For CAL type instructions, a method for determining which registers need to be saved is executed in a minimum number of cycles, examining groups of register mask bits at one time.  Internal processor registers are accessed with short (byte width) addresses instead of full physical addresses as used for memory and I/O references, but off-chip processor registers are memory-mapped and accessed by the same busses using the same controls as the memory and I/O.  If a non-recoverable error detected by ECC   circuits in the cache, an error transition mode is entered wherein the cache operates under limited access rules, allowing a maximum of access by the system for data blocks owned by the cache, but yet minimizing changes to the cache data so that diagnostics may be run. Separate queues are provided for the return data from memory and cache invalidates, yet the order or bus transactions is maintained by a pointer arrangement.  The bus protocol used by the CPU to communicate with the system bus is of the pended type, with transactions on the bus identified by an ID field specifying the originator, and arbitration for bus grant goes one simultaneously with address/data transactions on the bus.
