Abstract: ABSTRACT OF THE DISCLOSURE This invention provides an improvement in a high solids content coal-aqueous mixture comprising particulate coal as a dispersed solid material; water as a carrier medium; a polyalkyleneoxide nonionic surfactant having a hydrophobic portion and a hydrophilic portion, the hydrophilic portion comprising at least about 100 units of ethylene oxide, the poly-alkyleneoxide nonionic surfactant being present in the mixture in an amount to disperse the particulate coal in the water carrier. The improvement is wherein the mixture includes fuel oil in an amount effective to increase the stability of the mixture and a viscosity stabilizing amount of a viscosity stabilizer. The improvement provides coal-aqueous mixtures of increased stability, that is, they experience even less settling and have increased shear stability as well as being characterized with lower viscosity of both the unthickened and the finished slurry. The compositions also have improved combustibility.

Abstract: METHOD AND SYSTEM FOR PROVIDING SYSTEM SECURITY         IN A REMOTE TERMINAL ENVIRONMENT            Abstract of the Disclosure A security system and method for gaining access to files in a central processor from a remote terminal.  A user's secret PIN number and desired file number are entered at a terminal and are used to compute a second number which is compared with an internally generated first number.  Upon comparison, the requested file number is sent to the central processor which generates a random number.  The central processor sends the random number back to the terminal which uses the random number its assigned terminal number, and an algorithm to generate a third number.  At the same time, the central processor uses this random number and the terminal number and algorithm which are both associated with the desired file number to calculate a fourth number.  If the third and fourth numbers properly compare in the central processor, the terminal is verified and access to the desired file number is allowed.

Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus for a microinstruction controlled unit to recover from a read error in reading microinstructions from a control store.  The method provides for the overlapping of the execution of a current microinstruction while the next microinstruction is being addressed and read from the control store.   Execution of  the  current microinstruction is  begun before it is known whether or not it was read without error. The  apparatus  provides  for  aborting  the  execution  of  the current microinstruction with  the  read error  and  the  next microinstruction.   During the aborted execution of  the next microinstruction,  the current microinstruction is reread from the   control   store  and  then  executed  while   the   next microinstruction  is   being   reread.      The   execution   of microinstructions is aborted in a manner that does not alter the state of the microinstruction controlled unit beyond the point  that  would  inhibit  the  re-execution  of  the  aborted microinstructions.

The packaged chip has a plurality of lead frame conductors extending through the encapsulating material which are adhesively joined to the semiconductor chip, preferably by means of an alpha barrier.  The conductors cover a substantial portion of the surface of the chip and thereby serve as conduits for the dissipation of heat from the chip.  Wires are bonded to the conductors and extend from the conductors to the terminals on the semiconductor chip.  In a preferred embodiment the semiconductor chip terminals are located along a center line of the chip.  This allows for short connecting wires which in turn contribute to faster chip response.

Abstract: Abstract of the Disclosure An improved magnetic recording disk drive,  in particular a flexible disk drive,  includes a head positioning servo system which utilizes servo informa-tion recorded on the disk by the disk drive.  The servo information is located within one of the data sectors and is in the form of a pattern of radially spaced-apart segments, each segment overlapping a number of data tracks and comprising magnetic transitions which increase in frequency in the radial direction to provide a digital head position error signal (PES).  A similar segment is located in each of the other data sectors around the perimeter of the disk to provide track profile information so that the head positioning system can compensate for disk runout and distortion. The disk drive includes means for eliminating the effect of the amplitude of the readback signal from the servo and profile segments on the head positioning system, thus assuring a reliable PES at all radial locations on the disk and allowing interchangeability of disks among disk drives.

Abstract: Abstract of the Disclosure:     A fast settling amplifier for use in a phase locking system operative to phase lock a local clock to incoming data bits in a packet of short duration within a specified accuracy range, using no more than a few initial bits of the packet. Phase locking is achieved by phase shifting the data packet bits relative to a local clock signal a fixed, non-integral fraction of a bit period until the phasing lies within the specified range. The phasing is then accurate enough to permit signal decoding with an open loop over the limited duration of the packet. The phase locking process is activated each time the beginning of a new packet is detected. A Manchester code is typically utilized as the representation of the signal upon which synchronization is achieved. The Manchester code or biphase signal is recovered from the telecommunications network by a fast settling amplifier that rapidly establishes thresholding to accurately distinguish between high and low level signal levels in the Manchester code while maintaining a well filtered signal level.
