Patent CA-2332534-C (CA)
Inventor: ANDRIEN BRUCE A JR
IPC: H01J49/06

Granted: 2008-07-22
Abstract: A mass spectrometer (40) is configured with individual multipole ion guides (60, 62) configured in an assembly in alignment along a common centerline (5 ) wherein at least a portion of each multiple ion guide (60, 62) mounted in th e assembly resides in a vacuum region (72, 73) with higher background pressure . Said multiple ion guides (60, 62) configured in a higher pressure vacuum region (72, 73) are operated in mass to charge selection and ion fragmentati on modes. Individual sets of RF, +/- DC and resonant frequency waveform voltage supplies provide potentials to the rods of each multiple ion guide allowing the operation of ion transmission, ion trapping, mass to charge selection an d ion fragmentation functions independently in each ion guide (60, 62). The presence of background pressure maintained sufficiently high to cause ion to neutral gas collisions along a portion of each multiple ion guide linear assembly allows the conducting of Collisional Induced Dissociation (CID) fragmentation of ions by axially accelerating ions from one multiple ion gui de into an adjacent ion guide, analoguous to a triple quadruple ion function.</ SDOAB>

Abstract: - 52 - In a method and an apparatus for transmitting information symbols using a plurality of carriers, the first transmission symbol is generated from an information symbol. Furthermore, a second transmission symbol is generated from the same information symbol, wherein the second transmission symbol is different to the first transmission symbol. The first and second transmission symbols are modulated on carriers, and transmitted at different times. A Method and an Apparatus for receiving information symbols, which are represented by the first and second transmission symbols, use the two transmission symbols received in order to arrive at the information symbol on which the two transmission symbols are based.
Patent CA-2349805-C (CA)

Granted: 2004-11-02
Abstract: A spiked H-style link for a sharp chain conveyor where the single centrally-placed saddle of the prior art is replaced by a double saddle with a centrally-located opening shaped to receive a sprocket tooth. The double saddle moves each saddle outward from the central portion of the spiked link to enhance the rigidity of the legs between which the connecting pins act. The legs are provided with a thickened offset step on the lower inner portion of each leg. There is a corresponding decrease in the thickness of the legs in the region where the connecting link works. By decreasing the thickness of the legs in the region outside the offset step, the connecting link may be widened, allowing for a greater bearing surface on the connecting pin and thus reducing the rate of wear on the connecting pin.
