Patent CA-1295544-C (CA)
Inventor: LUCADAMO GENE A
IPC: F25J3/02
Filed: 1987-07-29
Granted: 1992-02-11
Abstract: ABSTRACT    A low capital cost, energy efficient process for separation of carbon dioxide, sulfide gases and hydrocarbons from carbonaceous off-gas streams, for example, oil shale retorting off-gases, coal gasification off-gases, oxygen fire flooding off-gases or carbon dioxide miscible flood enhanced oil recovery off-gases is disclosed.  The process comprises separation of the off-gases into an essentially sulfur-free light fuel gas, a heavy hydrocarbon stream and a carbon dioxide gas stream wherein the off-gas is compressed if necessary and cooled prior to separation of the various streams in a distillation column.  The carbon dioxide stream is expanded in an auto-refrigeration step to provide some of the necessary process refrigeration.

Title: Input output interface controller connecting a synchronous bus to an asynchronous bus and methods for performing operations on the buses
Inventor: BOURKE DONALL G
IPC: G06F13/40
Filed: 1987-08-12
Granted: 1992-03-24
Abstract: ABSTRACT OF THE DISCLOSURE            In a data processing system, an input output bus unit (IOBU) is connected to one end of an input output interface controller (IOIC) via an asynchronous bus.  The other end of the IOIC is connected to a storage controller (SC) and an input output interface unit (IOIU) via a synchronous bus. The SC and IOIU are connected to a memory unit and an instruction processing unit.  The asynchronous bus, which is comprised of three sub-buses and a control bus, conducts signals between the IOIC and an IOBU in an asynchronous "handshaking" manner. The synchronous bus, which is comprised of two sub-buses and a control bus, conducts signals between the IOIC and the SC/IOIU in an synchronous manner.  The IOIC, interconnected between the synchronous bus and asynchronous bus, functions as a buffer between the faster synchronous bus and the slower asynchronous bus.  Various operations are performed between an IOBU and the memory unit via the asynchronous bus, IOIC, synchronous bus, and SC/IOIU, such as a unit operation, a storage operation, and a message acceptance operation.

Title: High speed serial pixel neighborhood processor and method
Inventor: KRICH DAVID M
IPC: G06T5/20
Filed: 1987-12-17
Granted: 1991-07-16
Abstract: ABSTRACT     A serial pixel neighborhood processor serially receives successive rows of pixels at a 10 MHz rate, and operates on three digit by three digit pixel "neighborhoods" to serially output filtered pixels at the 10 MHz rate.  The processor includes first through sixth 16 kilobit memories.  Odd numbered rows of pixels are serially written into the first memory and even numbered rows of pixels are serially written into the fourth memory.  Odd numbered rows of pixels in the first and second memories are serially shifted into the second and third memories, respectively, while even numbered rows of pixels are being written into the fourth memory.          Similarly, even numbered rows of pixels in the fourth and fifth memories are serially shifted into the fifth and sixth memories, respectively, while odd numbered rows of pixels are being written into the first memory.  The outputs of all of the memories are multiplexed into three bit serial to parallel converters.  The nine outputs of the three serial-to-parallel converters produce nine bit pixel neighborhoods each centered about a successive object pixel at the ten MHz data rate.
