Title: Attachment system for mounting road maintenance equipment on a vehicle
Inventor: MCMILLAN PERRY DARRELL
IPC: E02F9/00
Filed: 1996-07-17
Abstract: An attachment system for mounting road-maintenance equipment on a vehicle such as a motor grader includes a frame for mounting on the nose plate of the vehicle to straddle one of the front wheels and support the conditioning equipment outboard of the vehicle. The system includes pivotal attachment mounts for the front and rear ends of a draft frame of the conditioning equipment together with means for supporting the draft frame at a desired orientation during operation, and for raising the draft frame and surface conditioning equipment to a retracted position when not in use. A mast on the attachment system frame directs a cable to the rear end of the draft frame to effect raising movement of the latter to the transport position when desired.

Title: Data rate estimating device
Inventor: HAYASHI HIROSHI
IPC: H04B1/707
Filed: 1996-08-22
Abstract: A digital communication system is disclosed. A transmitter combines a digitized signal into a digital data stream with variable data rate and trnasmits it to a receiver. The receiver decodes the received signal with an actually transmitted data rate. For this reason, the receiver has to estimate the coding data rate of the received signal. The receiver decodes the received signal at one decoding rate, which is evaluated whether the decoding rate is correct or not. Such evaluation is achieved by, for example, measuring S/N ratio. According to such estimation the receiver estimates the actual transmitted data rate.

IPC: C01F7/062
Filed: 1995-08-23
Abstract: Un procédé, qui permet d'extraire l'alumine à partir d'une bauxite à relativement forte teneur en boehmite, consiste en des étapes de digestion de la fraction de gibbsite contenue dans la bauxite pendant environ 2 à 2,5 minutes, à une température d'environ 135 à 145 ~C et selon un rapport A/C d'environ 0,76, pour parvenir à une réversion de boehmite négligeable, à une dissolution pratiquement complète de la kaolinite et à une précipitation pratiquement nulle de produits de désiliciage. Ce procédé consiste ensuite à soumettre la fraction liquide provenant de l'étape de digestion de gibbsite à un post-désiliciage en présence de germes d'hydroxysodalite pour ramener la concentration en silice près de la solubilité d l'hydroxysodalite, puis à soumettre cette fraction liquide à un désiliciage secondaire à l'aide d'un aluminate de tricalcium produit à part par l'adjonction de chaux à une liqueur épuisée pour minimiser les pertes d'alumine à partir de la liqueur sursaturée et réduire la teneur en silice de la liqueur épuisée afin de limiter l'entartrage, puis à soumettre le résidu de digestion de gibbsite à une étape de digestion supplémentaire pour digérer la boehmite, cette digestion de la fraction de boehmite intervenant à une température plus basse et/ou pendant un temps de résidence plus court qu'il n'est habituel.

Title: Probe masking method of reducing background in an amplification reaction
Inventor: BRAINARD THOMAS D
IPC: C12Q1/68
Filed: 1996-05-30
Abstract: A method for reducing background caused by target-independent generation of amplification products, typically the products of a ligase chain reaction or a polymerase chain reaction, involves chemically "masking" or blocking the amplification probes or primers so that they cannot be extended or ligated until the occurence of a triggering event which can be delayed until the amplification reaction is begun. The probe masks take the form of complementary blocking oligonucleotides that are incapable of serving as template themselves and inhibit random tailing of the probe/primers. The blocking oligo masks are denatured from the probes during amplification and preferably are effectively eliminated from competing for probes in the amplification reaction
