Patent CA-2405858-A1 (CA)
Inventor: BERGMAN GEORGE
IPC: F24F7/06
Filed: 2002-10-01
Abstract: A stairwell pressurization system is interconnected to a fire alarm for simultaneous operation. As a result, when the fire alarm system is sounding, the pressurization system is used to create a positive pressure in the stairwell and prevent smoke or substantially reduce any smoke penetration into the stairways. The system includes one or more fans which are operated at the same time as the existing fire alarm system. The operation of the fans forces smoke free air from outside the building into the top and bottom of each stairwell. This creates a positive air pressure in the stairwell, which prevents the movements of smoke from the building hallways and common areas into the stairwells, creating a safe area for individuals to exit the building. The system maybe further configured to turn off any secondary roof top ventilation system which provides airflow to the building hallways or common areas. This advantageously reduces pressure from the common and hallway areas, resulting in enhanced airflow from the pressurized stairwells into the hallways. In case of stairwell exit doors being opened simultaneously, pressure sensors in the stairwells are used to sense a pressure drop. Upon sensing a pressure drop, the sensors are used to provide control signals to the fans to operate at increased power and speed until the pressure in the stairwell is returned to a desired level.

Title: Variable shut off teat cup liner
Inventor: MCLEOD RICK
IPC: A01J5/08
Filed: 2002-12-31
Abstract: A variable shut off teat cup liner has a mouthpiece, a barrel and a short milk tube adapted for mounting onto a nipple of a milking claw. The short milk tube includes a segment intended for engagement with an edge of the nipple defining an opening, the segment being intended for bending over the opening to substantial close it to passage of vacuum-drawn air therethrough when the teat cup liner is in a non-milking generally downwardly bending position.

Title: Mass spectrometry method and apparatus
Inventor: SENKO MICHAEL W
IPC: H01J49/42
Filed: 2002-03-20
Abstract: A mass spectrometer (10) comprises an ion source (12) which generates nebulized ions which enter an ion cooler (20) via an ion source block (16).  Ions within a window of m/z of interest are extracted via a quadrupole mass filter (24) and passed to a linear trap (30). Ions are trapped in a potential well in the linear trap (30) and are bunched at the bottom of the potential well adjacent an exit segment (50). Ions are gated out of the linear trap (30) into an electrostatic ion trap (130) and are detected by a secondary electron multiplier (10). By bunching the ions in the linear trap (30) prior to ejection, and by focussing the ions in time of flight (TOF) upon the entrance of the electrostatic trap (130), the ions arrive at the electrostatic trap (130) as a convolution of short, energetic packets of similar m/z. Such packets are particularly suited to an electrostatic trap because the FWHM of each packet's TOF distribution is less than the period of oscillation of those ions in the electrostatic trap.
