Title: Total protein detection method
Inventor: PUGIA MICHAEL J
IPC: G01N33/493
Filed: 1998-07-03
Abstract: Disclosed is an improved assay for the determination of total protein in an aqueous test fluid such as urine. The assay involves combining the test fluid with a molybdate or tungstate salt and a dye which forms a complex with molybdate or tungstate ion at a pH of 1.0 to 3.0 to shift the absorption band of the complex in the presence of protein. There is introduced into the assay a substituted phenolsulfonephthalein dye having a pKa which enables it to operate at a pH of from about 1.0 to 3.0 and whose affinity for protein is such that it will provide a detectable response only in the presence of greater than 50 mg/dL of protein to increase the scope of the assay.

Title: Method and system for parallel demodulation of multiple chips of a cdma signal
Inventor: SPOCK GREGORY PETER
IPC: H04B7/216
Filed: 1997-12-05
Abstract: In a code division multiple access (CDMA) signal demodulator in a communication system (50), samples of a CDMA signal are stored in a sample buffer (52). A plurality of the samples that represent a plurality of chips of a symbol are then recalled from the sample buffer (52). Thereafter, the plurality of samples are demodulated in parallel (56) using a selected user code (68) to produce at least a portion of a user's symbol in the code division multiple access signal. Signals from multiple users (22, 24) having multiple fingers are demodulated by sharing the resources of a parallel demodulator (56). Signal searching may use the same parallel demodulator (56).  Fingers for multiple users may be dynamically allocated and reallocated according to the needs of each user's signal and the total demodulation resources available.

Title: Coil car structure
Inventor: FORBES JAMES W
IPC: B61D3/16
Filed: 1998-10-07
Abstract: A railcar unit has a pair of deep sidewalls and a cradle mounted between the sidewalls for carrying coils. The sidewalk span the distance between the two railcar trucks, and act as a pair of deep beams for carrying vertical loads. The deep sidewalls are arranged to extend above and below the centre sill of the cradle and to give vertical stiffness to the car. The centre sill is a straight through sill for carrying buff and draft loads between the couplers. The cradle is made from a set of cross bearers welded to the centre sill to form a series of segmented beams, covered by plating. The cross bearers are welded to the sidewalls at lap joints. The cross bearers are all of the same design and can be made from a rolled beam. The sidewalls have their deepest section at mid-span, and are tapered to a thinner section toward the end structure of the cars. The tapering includes provision of an access way between the railcar truck wheels and the sidewall to permit brake maintenance.

Patent CA-2264574-A1 (CA)
Inventor: WALLER CLIVE
IPC: G01F23/30
Filed: 1997-09-02
Abstract: L'invention porte sur un dispositif de contrôle à temporisation de niveau de fluide (10), ce dispositif étant destiné à contrôler le niveau d'huile dans le carter d'un compresseur (non figuré). Ce dispositif comporte un logement (12) délimitant une cavité intérieure (18) et dont une extrémité (16) est pourvue de deux orifices (20 et 22) permettant une communication fluidique entre l'intérieur du carter du compresseur et la cavité (18). L'orifice 20 est un trou de réduction de passage réduisant le débit de fluide entre la cavité (18) et le carter de sorte qu'il se produit un certain retard dans l'équilibrage des niveaux de fluide à l'intérieur du carter et de la cavité (18). L'orifice 22 est celui d'un trou d'aération. Un flotteur (24) est installé, grâce à un montage lui permettant de pivoter, dans une extrémité de la cavité (18) avec un aimant (36) lui permettant de commuter un commutateur à lames souples (26) situé entre les parois du logement (12). Si la durée de variation du niveau de fluide à l'intérieur du carter, entre les bords opposés d'un niveau prédéterminé, est inférieure au retard, le niveau de fluide ne varie pas dans la cavité (18) autour du niveau prédéterminé et, par conséquent, le déplacement du flotteur (24) est insuffisant pour entraîner une modification de l'état du commutateur à lames souples (26). Si la durée de la variation est supérieure au retard, le flotteur (24) pivote selon un degré donné, ce qui entraîne une modification dans l'état du commutateur à lames souples (26) et, partant, reflète la modification du niveau de l'huile dans le carter.
