Patent CA-2075048-C (CA)
Title: Networked facilities management system
Inventor: PASCUCCI GREGORY A
IPC: G06F17/30
Filed: 1991-01-25
Granted: 1999-08-17
Abstract: A networked system having a wide variety of applications and particularly applicable to facilities management systems has multiple levels of software in processing nodes. The levels include a "features" processing level which communicates requests for data to a software object level containing databases of processes and attributes and database managers.      The database managers in the software object level operate to provide data to the high level features in the same format. The software object level communicates with a hardware object level which also contains databases and database managers to mask differences between operational hardware units. By categorizing operational units by type, additional units of a known type can be added with only low level hardware object database changes. Adding units of a new type is facilitated by software changes confined to the lower level hardware and software objects, avoiding software changes at high level features. Individual software objects are tailored for typical types of inputs and output devices encountered by facilities management systems. Universal drive circuitry also provides applicability to a broad range of devices.

Title: Production of fluoxetine and new intermediates
Inventor: SCHWARTZ EDUARD
IPC: C07C217/48
Filed: 1992-08-12
Granted: 1997-10-14
Abstract: 4-methyl-3-[(4-trifluormethyl)phenoxy]-3-phenyl propylamine (I) is prepared by reacting 3-dimethylamino-1-phenyl-1-propanol (III) with haloformate (VIII) to obtain a substituted propyl carbamate (IX) which is hydrolyzed under basic conditions to yield methylamino-1-phenyl-1-propanol (X).  The methylamino-1-phenyl-1-propanol is then converted to fluoxetine (I) by reaction with 4-halo-benzotrifluoride (XI).           In the process certain substituted carbamates are obtained as intermediates.

Abstract: A cover forming apparatus for forming a flower pot or flower pot cover from a sheet of material by engaging a sheet of material about the outer surface of a mold, die or pot.      The cover forming apparatus includes a plurality of pivotable forming members resting in a surface which supports a sheet of material upon which is positioned a flower pot mold or flower pot. When the forming members are pivotally moved from the storage position to an extended position, the forming members cause the sheet of material to be appressed to or engaged with the mold or pot. The article formed in accordance with the present invention may be separable from the mold or pot and usable as a flower pot or flower pot cover or may be more or less securely attached to the pot by adhesive, cohesive, barbs, friction pinches or other securing means thereby forming a decorative cover connected to a flower pot. The forming members may be spaced by gaps in their closed positions, and gathering fingers can be employed in functional relationship to the forming members to produce different pot or cover features. The cover forming apparatus may be incorporated within a mobile platform enabling the cover forming apparatus to be moved from one location to another.

Abstract: A gas investigation apparatus is provided herein to determine the amount of gas in a liquid. The apparatus includes a hollow, longitudinally-extending cylindrical barrel for holding a liquid and a sample liquid with gas dissolved therewithin and with an associated gaseous headspace above. The barrel has a lower inlet and an upper outlet. At least a portion of the barrel is transparent. A plunger is slidably-fitted in a leak-proof manner within the barrel, the plunger being free to slide along the longitudinal length of the barrel, thereby forming a variable volume of air and gas in the headspace.  A gas inlet tube has a lower inlet, and an upper outlet within the plunger and extends along the longitudinal axis of the plunger. A longitudinally-extending, heat transfer jacket surrounds the cylindrical barrel for the regulation of the temperature of the liquid sample. An upper valve is connected to the upper outlet of the barrel by means of a zero dead-space, butt-end connection. Selective entry means is provided through the upper valve for admitting a study liquid or tissue suspension into the barrel. A lower valve is connected to the lower inlet of the gas inlet tube by means of a zero dead-space, butt-end connection. An inlet conduit is provided for the selective introduction of test gas, a calibration gas, a carrier gas, or a flushing gas into the gas inlet tube through the lower valve. An inlet tube is provided for the selective introduction of a gas sample into the inlet conduit means through the lower valve. Finally, an exit tube is connected to the upper valve by means of a zero dead-space, butt-end connection, for leading gas exiting from the plunger-position-dependent variable volume of gaseous space at the upper portion of the barrel to a mass spectrometer.

Abstract: A cable crosstalk measurement system provides fault diagnostic information to locates faults in addition to providing a crosstalk versus frequency function to test and troubleshoot LAN cables. In a preferred embodiment, a narrow pulse is introduced into one twisted pair of a standard LAN cable, and another twisted pair in the same cable is monitored for crosstalk signal coupling . A measurement system digitizes crosstalk signals using sequential sampling of repetitive signals to provide a waveform record that is a reconstructed equivalent time representation of a real-time crosstalk signal. A microprocessor performs a fast Fourier transform of the waveform record to provide crosstalk versus frequency information, while the waveform record is also examined for higher-than-acceptable amplitude levels to locate poor quality or faulty connectors and cables.
