Patent CA-2287499-C (CA)
Title: Rf-only mass spectrometer with auxiliary excitation
Inventor: COUSINS LISA
IPC: B01D59/44
Filed: 1998-04-22
Granted: 2006-11-07
Abstract: An RF-only quadrupole mass spectrometer in which an auxiliary RF field (dipole or quadrupole) excites selected ions at low q (typically between 0.20 and 0.89). The excited ions experience radial excursions, but many do not experience excursions sufficient to strike the rods, and are therefore transmitted and acquire increased kinetic energy in the fringing fields at the exit ends of the rods. The excited ions may therefore be selected from the non-excited ions either by their increased axial kinetic energy, or by their radial dispersion, or both, and are detected for analysis, producing sharp peaks of high sensitivity at low q, while retaining the high acceptance and other advantages of RF-only mass spectrometers. Operated in converse fashion, a high quality notch filter can be achieved. In the notch filter, an auxiliary RF field again excites ions and notches some of them out by causing them to strike the rods. Ions which are not notched out but which are nevertheless excited by the auxiliary field are discriminated against, again either by reason of their higher axial kinetic energy or their spatial dispersion or both, so that only ions on axis are detected, producing a high resolution high sensitivity notch filter.

Title: Door operator control system and method
Inventor: REED BRETT A
IPC: E06B9/68
Filed: 2000-05-12
Granted: 2004-11-02
Abstract: An operator control system for controlling the operation of an electric motor driven door or gate operator unit having a speed reducing gear drive mechanism and a brake unit for positive braking of the motor output shaft. A programmable microcontroller is operably connected to a motor drive circuit with interlock relays to energize the operator unit drive motor for rotation in opposite directions. The motor drive circuit is interconnected with a motor watchdog circuit to effect motor shutdown if the microcontroller malfunctions. The motor drive circuit is operably connected to a brake release circuit to prevent motor operation unless the electrically operated brake is energized to release braking of an operator output shaft. The microcontroller receives input signals from manually or radio-controlled door open, close and stop switches and from door position limit switches. The microcontroller is connected to a non-volatile memory for storing door mid-stop time delay values, braking rates, a door position limit overrun signal, a door cycle count, door reversals upon receiving an obstruction detector signal and error codes associated with door operator and control system malfunctions. The door may be operated to provide a down position limit overrun, progressive braking and a mid-stop set position by time based signals. The electrically operated brake may be controlled on a variable duty cycle to provide smooth braking action in both directions of movement of the door.

Abstract: An analytical rotor (10) for separating cellular components from a biological sample includes a plurality of internal chambers and passages for combining the cell-free sample with one or more reagents and distributing the sample to a plurality of individual test wells (92). The chambers and passages necessary for separating cellular components from a sample such as whole blood include a measuring chamber (40), an overflow chamber (44), a separation chamber (60), and a reagent chamber (80). The measuring chamber (40) and overflow chamber (44) have capillary dimensions so that an initial volume of whole blood partitions therebetween, with the measuring chamber filling first to provide a preselected volume. The separation chamber (60) is located radially outward from both the measuring chamber (40) and the reagent chamber (80) so that spinning of the rotor causes both the reagent and the measured blue volume to flow outward into the separation chamber (60). A collection chamber (90) is formed to receive the plasma from the separation chamber (60). Further spinning of the rotor causes the plasma to flow radially outward into a plurality of test well (92) formed around the periphery of the collection chamber (90). Testing of the separated plasma volumes may be performed without removing the plasma from the rotor.

Abstract: A lock for securing the head of a fuelling machine, defuelling machine or inspection machine to the end fitting of a fuel channel of a nuclear reactor is a rod and piston lock which engages or disengages according to the differential between the pressure in the snout cavity and the pressure in the fuelling machine magazine. The lock is engaged when the snout cavity pressure and the fuelling machine pressure are substantially equalized. When the pressure in the snout cavity is reduced sufficiently below the level of the pressure in the fuelling machine, the lock is engaged. The lock remains engaged if there is a drop in reactor pressure during refuelling and during reactor shutdown conditions. Engagement of the lock prevents inadvertent unclamping of the fuelling machine from the fuel channel.
