Title: Panel, clip and method of mounting panel
Inventor: GOODWORTH JOHN P
IPC: E04B2/74
Filed: 1991-07-22
Granted: 1995-07-04
Abstract: A panel assembly includes a resiliently deflectable panel and a plurality of retainer clips. The panel includes a relatively thick rectangular base section and a relatively thin rectangular lip section which extends outwardly from the periphery of the base section.  The retainer clips are connected with the base section and cooperate with the lip section of the panel to engage a support structure to hold the panel in place.  To mount the panel in the support structure, the panel is resiliently flexed.  The panel is then released and its natural resilience causes a retainer clip to engage the support structure to hold the panel against movement relative to the support structure.  A disengagement tool may advantageously be inserted between the panel and the support structure to apply force against the retainer clip and to resiliently flex the panel to disengage the retainer clip from the support structure.

Patent CA-2062629-C (CA)
Title: Apparatus and method for liquid sample introduction
Inventor: FRENCH JOHN BARRY
IPC: H01J49/04
Filed: 1992-03-10
Granted: 1999-06-15
Abstract: A liquid sample to be analyzed is fed to an ink jet printer micro pump.  The pump directs the solution, as a stream of uniformly sized and spaced droplets, into a laminarly flowing stream of hot carrier gas.  The carrier gas evaporates the solvents (e.g. water) in the droplets to form a stream of dried particles.  The particles are vaporized by a plasma, laser or other heat source.  The vapour can be ionized and the ions analyzed by a mass spectrometer, or the vapour can be analyzed by optical spectroscopy.  The method reduces oxide and other interference effects, increases sample utilization, and reduces waste,  signal  noise,  and  memory  effects,  increasing instrument productivity.  Multiple nozzles can be used to change samples or to shoot calibrating droplets, further increasing productivity.   Signal detection can be synchronized with droplet firing, or the signal, which is intrinsically modulated at the drop frequency, can be low pass filtered and synchronously detected, to increase the signal to noise ratio.  The dried particles can also be directed into a vacuum chamber and deposited in a desired pattern on  a surface  in the vacuum,  thus  delivering controlled micro-dosages of material onto the surface.
