Title: Separateur de plastique
Inventor: DUBE JEAN-DENIS
IPC: B07B1/10
Filed: 1999-12-29
Abstract: La présente invention se veut une méthode de séparation des pellicules de plastique de différents produits organiques tels les composts, les sols, les paillis, le bois broyé, etc. Le processus de séparation de plastique permet de récupérer la portion de matériel fin habituellement présente dans le produit  à traiter. La méthode utilisée consiste à amener le produit dans un cylindre rotatif mu ni de palettes de levage. L'action rotative du cylindre a pour effet de souleve r le produit, favorisant ainsi l'emprise du vent sur les pellicules de plastique présentes dans le produit. Une souffierie, placée à l'entrée du cylindre, propulse les matériaux légers (dont les pellicules de plastique) sur un convoyeur vertical, placé à la sortie du cylindre. Ce convoyeur est doté d'une courroie grillagé e. Le plastique est maintenu sur cette courroie grâce à la pression de la souffler ie alors que les matériaux fins passent au travers du grillage. Les matériaux lourds qui ne sont pas propulsés par la soufflerie tombent au pied du cylindre rotatif et sont récupérés par un convoyeur.  Le convoyeur grillagé amène le plastique jusque dans un compacteur de plastique. Le matériel fin est recueilli dans une boîte munie de chicanes. L es chicanes forcent le matériel fin à se déposer sur un convoyeur alors que l'a ir est évacué par une sortie située sur le haut de la boîte.

Title: Wireless radio frequency technique design and method for testing of integrated circuits and wafers
Inventor: MOORE BRIAN H
IPC: H01L21/822
Filed: 2000-05-15
Abstract: A wireless technique for testing of Very Large Scale ICs and wafers is presented. Presented is a test technique that uses standard CMOS without the use of inductors to achieve wireless parametric testing. In terms of existing technologies this system has virtually no area overhead, minimal power requirements and no process or design changes are required. A major feature is that wafer contact is not required. This work shows that a considerable reduction in testing time is possible with this technique. Also presented are specific circuits and simulations showing characteristics of operation under varying conditions.    The circuit operation is shown to work down to a 1 volt and sub milliwatt power level at the same time as being 1/10000th the area of a Pentium class VLSI circuit.
Patent CA-2310281-A1 (CA)
Inventor: GOLDSTEIN GARY ALLAN
IPC: H04L9/14
Filed: 1998-11-10
Abstract: In a telecommunications system, data having a higher sensitivity and data having a lower sensitivity are identified within a data set. The data having a higher sensitivity is encrypted to produce encrypted sensitive data.  Thereafter, the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The encrypted data set is then transferred from a sending unit to a receiving unit. Decryption information may be appended to the encrypted sensitive data before the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The decryption information may include an algorithm identifier, a key identifier, and receiver response instructions. At the receiving unit, the data set is decrypted to recover the data having lower sensitivity. A second decryption of the encrypted sensitive information recovers the data having a higher sensitivity. Appended decryption information may be used to locate and decrypt the encrypted sensitive information.

Title: Method and device for recording information in units
Inventor: SPRUIT JOHANNES H M
IPC: G11B5/09
Filed: 1999-12-06
Abstract: A method and device for recording information signals on a partly recorded writable record carrier (11), e.g. an optical disc. An information signal represents at least one information unit. The record carrier has a recording track with comprises preformed track position information indicative of locations for recording the information units. From the information signal a modulated signal is generated having successive frames, each frame including a synchronizing signal. The modulated signal is recorded at a one of said locations, while maintaining a fixed relationship between the track position information and the synchronizing signals. In the event that the location is after and adjacent to an already recorded location, the recording is started at a link position (31) before the end of a last frame of the earlier recorded information signal at a predefined distance before a first synchronizing signal (30) of the modulated signal.

Title: Endotoxin reduction in nucleic acid purification
Inventor: CRESWELL DONALD A
IPC: C12Q1/68
Filed: 1999-04-22
Abstract: The present invention presents a novel method for removing endotoxins from nucleic acids, such as DNA, RNA, or hybrids thereof, contaminated therewith.  Nucleic acid solutions which can be treated using the method of this invention include, but are not limited to, lysates of gram-negative bacteria and nucleic acid solutions contaminated with endotoxins from external sources. The present method removes endotoxins from such solutions using silica-based materials, such as silica gel particles, magnetic silica particles, or diatomaceous earth. In a preferred aspect of the method of this invention, magnetic silica particles are used to isolate plasmid DNA from a lysate of gram-negative bacteria transformed with the plasmid DNA. Application of the disclosed method produces nucleic acids which are sufficiently free of endotoxin contamination to be useful for a variety of different practical applications. Figure 1 shows a plot of units of endotoxin bound vs the number of milligrams of particles added to lysates of each of two differerent strains of bacteria, JM109 (◊) or DH5.alpha.(♦).
