Title: Assembly language programming potential error detection scheme sensing apparent inconsistency with a previous operation
Inventor: HANSEN ROBERT G
IPC: G06F11/36
Filed: 1990-11-19
Granted: 1994-07-05
Abstract: ABSTRACT OF THE DISCLOSURE      A computer aided software engineering tool is disclosed which is particularly well adapted to identity potential Assembly language  source code  errors  resulting  from the analysis  of  statements  which  do  not  contain  incorrect syntax, limits, operand specification,  etc.;  i.e., do not contain  any  errors  of  the  type  which  can  be  generally categorized as incorrect usage.  This objective is achieved by  providing  a  debugging  program  which  has  a  complete awareness of the specific machine architecture, such as the function of  each instruction and the register(s),  flags, etc.  it  affects.    By  essentially  stepping  through  the Assembly language statements in much the same manner as a computer   would   while   executing   the   corresponding instructions, the debugging program is able, through such simulation, to identify,  in the Assembly language program under  study,   specific  potential  inconsistencies  with previous operations which the debugging program has been coded  to  detect  and,  upon such  detection,  to  issue  an appropriate  warning  message.    The  programmer  may  then examine the flagged Assembly language code to determine if a genuine error exists.

Filed: 1991-01-28
Granted: 1993-04-27
Abstract: ABSTRACT   An  apparatus  for measuring the diffusion  of hydrogen atoms  from a second surface to a first surface of a ferrous metal body as a means of measuring the magnitude of  corrosion  occurring  at  the  second  surface.    The apparatus comprises a chamber-defining member which can be sealed to the first surface of the body so as to define with the first surface a sealed chamber.   The chamber-defining  member  is  constructed  of  material sufficiently flexible that upon evacuation of the sealed chamber the chamber-defining member deflects toward the first  surface  to  reduce  the  chamber  volume.    The apparatus provides a connecting means for attaching an evacuating pump which is used to evacuate substantially all of the contents of the chamber.  A valve is provided to  isolate the  evacuated  chamber from the evacuation pump so that hydrogen atoms,  generated as a result of corrosion of the second surface, migrate through the body and exit the first surface within the chamber and combine to form hydrogen molecules which collect in the chamber. A vacuum gauge is provided to monitoring the decay of the vacuum in the chamber over time.

Title: System and method for monitoring synchronous blade vibration
Inventor: HILL PETER DOUGLAS
IPC: F01D25/00
Filed: 1992-01-29
Granted: 2004-04-13
Abstract: A system and method are provided for monitoring synchronous blade vibration in a turbo-machine. At least three sensors capable of detecting the arrival of each blade are arranged about the cylinder which surrounds the tips of the blades. The location of the sensors is selected to minimize the influence of errors in the data. To this end, and to simplify the installation of the sensors into the cylinder, the sensors may be non-uniformly spaced. The location of each sensor for purposes of constructing Fourier transforms is determined using the arrival times at the blades at peach sensor, expressed as a fraction of a rotor revolution.      The transform matrix is constructed for a predetermined discrete set of M harmonics, so that M harmonics are analyzed simultaneously, the number of harmonics which can be simultaneously analyzed is related to the number of sensors used. The blade arrival time data at each sensor, expressed as a fraction of a rotor revolution, is analyzed to determine the amplitude of the blade vibration at each of the harmonics selected for the set. The calculations are repeated for a variety of harmonic sets in order to accurately interpret the results in the event there is significant vibration at harmonics not included in the initial set.

Title: Coupled spinning and dewatering process
Inventor: SAMUELS SAM L
IPC: D01D4/02
Filed: 1992-02-21
Granted: 2002-06-11
Abstract: A continuous process for the manufacture of a fibrous material from a polyolefin. The process comprises feeding a solution of polyolefin dissolved in an organic solvent at elevated temperature and pressure to a spinneret. The exit of the spinneret is the inlet to an elongated vertical tube and is located in an upper section of an elongated vertical vessel. The tube extends for a major portion of the length of the vessel. Solvent is removed from an upper section of the vessel and water is sprayed both down the tube and into the vessel. The strands thus formed are shredded in a self-cleaning self-feeding shredder located at the bottom of the vessel. The shredded fibres and water are conveyed to a second vessel having a baffle located between the inlet and outlet thereof such that the shredded fibrous material passes from the inlet, over the baffle and to the outlet of the second vessel, the upper lip of the baffle being so that the level of water in the second vessel is in substantially the same horizontal plane as the shredder.      An inert gas e.g. steam, is fed to the second vessel to effect removal of volatile matter. The shredded fibres and liquid passing from the second vessel are fed to a dewatering device. The process may be used to manufacture fibrous polyolefin products e.g. in the form of a pulp.      The preferred polyolefin is a high molecular Weight homopolymer of ethylene or copolymer of ethylene and at least one C4-C10 hydrocarbon alpha-olefin.
