Patent CA-2469441-C (CA)
Inventor: MACDOUGALL TREVOR
IPC: G01L1/24

Granted: 2008-03-18
Abstract: Disclosed herein is an optical sensor design and method for continually interrogating that sensor to produce an accurate representation of a dynamic event (such as a change in strain, pressure or temperature) being monitored by the sensor. The sensor design preferably constitutes continuous wave optical source/detection equipment coupled in series to a first fiber Bragg grating (FBG), a long period grating (LPG), and a second FBG formed in an optical waveguide. The LPG broadly attenuates light in the vicinity of the Bragg reflection wavelength .lambda.2B of the second FBG, and this attenuation profile shifts in wavelength in accordance with the dynamic event being monitored. Perturbation of the attenuation profile thus attenuates the intensity of the light reflected from the second FBG, i.e., I(.lambda.B2), because such reflected light must pass (twice) through the LPG. Accordingly, continually monitoring I(.lambda.B2) as a function of time allows the dynamic event to be recreated and processed accordingly. If necessary, I(.lambda.B2) can be normalized by dividing it by the intensity of the Bragg reflection wavelength from the first FBG, I(.lambda.B1), to discard attenuation within the system not related to the dynamic event being monitored.

Abstract: In the dual port intake device of the present invention, the intake manifold assembly comprises three blocks each molded from a plastic material by injection molding, the three blocks consisting of a first block defining a half of the surge tank, a second block defining a half of the individual intake pipes and a third block defining a remaining half of the surge tank and a remaining half of the individual intake pipes. Thereby, the intake manifold assembly may be provided with various features for defining a pair of intake pipe sections arranged in a mutually parallel relationship while being made to be suitable for an injection molding process. Because the surge tank are defined by the first and third blocks (optionally with the aid of the second block) while the individual intake pipes are defined by the second and third blocks (optionally with the aid of the first block), the intake manifold assembly essentially consisting of three blocks can internally define essential features required for a dual port intake device without requiring additional component members.

Granted: 2011-06-21
Abstract: New process for the production of (6S)-5,6,7,8-tetrahydrofolic acid or derivatives thereof starting from the corresponding (6S, 6R) racemic mixture. The procedure comprises in the steps of adding an organic acid to a non-alkaline suspension of (6S,6R)-5,6,7,8-tetrahydrofolic acid, up to a pH value in the range of 1 to 3; heating the suspension from 30~ to 80~C; cooling the suspension from 20~ to 60~C, with selective crystallization of the (6S)-isomer. The procedure gives the (6S)-isomer in high yields and with a high degree of stereoselectivity. It follows that the synthetic access to a large number of pharmacologically active stereoisomers of folic acid is simpler and more effective.
