Abstract: "Phase-Locked Clock Regeneration Circuit for Digital Transmission Systems"                      ABSTRACT OF THE DISCLOSURE     In a digital transmission system, a clock regeneration circuit includes a phase-locked loop having a low-pass filter, a voltage-controlled oscillator connected thereto, and a phase comparator for supplying to the low-pass filter a signal representative of the phase difference between an incoming two-level data bit stream and the output of the voltage-controlled oscillator.  The incoming data bit stream is converted into a plurality of parallel data bit streams and fed to a multi-level quadrature amplitude modulator in response to a clock signal derived from the output of the voltage-controlled oscillator and converted into an outgoing multi-level digital signal.  An incoming CMI (coded mark inversion) coded binary signal is sampled by a flip-flop for in response to the output of the voltage-controlled oscillator to supply an output signal to the VCO through the low-pass filter.

Title: Lanced fin condenser for central air conditioner
Inventor: OBOSU CHARLES B
IPC: F28D1/04
Filed: 1987-05-21
Granted: 1992-02-11
Abstract: ABSTRACT An improved fin configuration is provided for use in central air conditioning unit heat exchangers in which heat transfer takes place between a first fluid, typically a refrigerant, flowing inside a nested plurality of tubes and a second fluid, typically air, flowing between the tubes and through a plurality of heat conducting fins attached to and arrayed between the tubes.  Lanced pairs of streamwise adjacent bridge-like formations, one out each side of a generally corrugated fin surface, provide numerous leading edges to generate a plurality of reforming velocity and heat transfer boundary layers which leads to an increase in flow turbulence for enhanced heat transfer between the fins and the second fluid.  By strategic location of a pair of such formations between tubes, with the upstream one of the pair at a positive angle of attack to the flow, air flow is directed through the fin to mix with flow on the other side of the fin and hence the heat transfer rate is improved.  The provision of a shallow conical annular fin region around each collar attaching a fin to a tube, preferably with a 6° inclination of the conical surface to a plane orthogonal to the collar axis, provides additional enhancement to the heat transfer between the fin and the second fluid.

Title: Burner for solid and other high ash fuels
Inventor: BAR DALI
IPC: F02C3/28
Filed: 1988-02-05
Granted: 1991-07-16
Abstract: ABSTRACT OF DISCLOSURE          A novel combustion device is installed into a gas turbine to permit operation with solid or other high ash fuels. A refractory burner block defines an annular primary combustion chamber and a number of secondary cyclonic combustion chambers positioned radially inwardly of the primary chamber. Waste wood or other solid fuels are charged into the primary combustion chamber. Pressurized combustion air flows derived from the turbine's compressor are introduced tangentially into the primary chamber thereby creating a vortex. A number of passages place the primary chamber in communication with the secondary chambers. These passages are formed in a radially inner wall of the primary chamber so that fuel particles are retained within the primary chamber by centrifugal forces until reduced to an appropriate size for combustion in the secondary chambers. The primary chamber exhaust flows and additional combustion air are introduced tangentially into each secondary chamber adjacent to a short exhaust tube leading to the turbine's runner thereby creating a vortex in each secondary chamber. Ash produced in each secondary chamber travels under the influence of the vortex along an inner chamber wall in a direction opposite to combustion gas flows through the exhaust tube and escapes radially through an opening distant from the exhaust tube.

Title: Apparatus and method for data induced condition signaling
Inventor: CUTLER DAVID N
IPC: G06F11/07
Filed: 1988-06-30
Granted: 1992-06-16
Abstract: ABSTRACT    In a data processing system, an instruction is disclosed that generates a fault when a predetermined register position (e.g., the low or least significant bit position) has a predetermined logic signal (e.g., a logic  'O'  signal).   This instruction provides a mechanism to determine when a Boolean value indicates a  presence  of  a  fault  condition  and  provides  a mechanism to generate the fault when present.   For example,  in arrays of memory locations that can be addressed by a program, this instruction can respond to the presence of an array address (or reference) that is outside the prescribed bounds of the array.          When an invalid address is identified, a signal is entered  in  the  low  (i.e.,  least  significant)  bit position  of  a  processor  scalar  register.   The instruction repertoire includes a Fault on Low Bit Clear  instruction  that  tests  the  contents  of  the scalar register low bit position,  and when a logic 'O'  signal is found therein, an exception signal is generated and applied to the control program of the data processing system.
