Patent CA-2388368-A1 (CA)
Inventor: SIMONDS EDWARD
IPC: F16D41/04
Filed: 1999-10-19
Abstract: A drive shaft assembly is provided for allowing rotation of a drive shaft in  a single direction. The drive shaft assembly includes a housing, a drive shaft  and an overrunning clutch. The overruning clutch includes an inner race havi ng an outer annular contact surface and an outer race having an inner annular contact surface spaced radially from the inner race. The inner annular conta ct surface and the outer annular contact surface form an annular space therebetween. Provided within this annular space are a plurality of sprags which allow the inner race to rotate in a first direction relative to the outer race while preventing the inner race from rotating in a second directi on to the outer race. A drive housing is secured to the outer race and a drive shaft is secured to the inner race so that when rotational force is provided  to the drive shaft in the first direction, the drive shaft rotates, but when  force is applied to rotate the drive shaft in the reverse direction, the torsional forces on the drive shaft are transferred through the overrunning clutch to the housing thereby preventing rotation of the drive shaft in the second direction. In the preferred embodiment, the drive shaft is coupled to  a piston assembly which transfers linear actuation of the piston to rotational  movement of the drive shaft.

Title: Device for fast and uniform heating of a substrate with infrared radiation
Inventor: LAPORTE FRANCK
IPC: H01L21/205
Filed: 2001-10-12
Abstract: The invention concerns a heating device comprising infrared radiation lamps (24, 26) for providing a fast heat treatment of a substrate (12) inside a reaction chamber (14) with transparent window (34). The infrared lamps (24, 26) are distributed on two superimposed stages (A, B) extending on a common side of the substrate (12), the lamps (24) of the lower stage (A) being arranged perpendicular relative to the lamps (26) of the upper stage (B). Means adjusting power input for each unit of lamps provide more heat on the edges than at the centre of the substrate (12). A reflector (36) is configur ed as a distribution grid (38) designed to reflect the infrared radiation to control the power ratios between the different heating zones. Thus the substrate (12) is uniformly heated, whatever its shape and its dimensions.</ SDOAB>

Patent CA-2401958-A1 (CA)
Title: Multiple gene expression for engineering novel pathways and hyperexpression of foreign proteins in plants
Inventor: MOAR WILLIAM
IPC: C07K14/325
Filed: 2001-02-28
Abstract: Introducing blocks of foreign genes in a single operon would avoid complications such as position effect and gene silencing inherent in putting  one gene at a time into random locations in the nuclear genome. Cloning several genes into a single T-DNA does not avoid the compounded variable expression problem encountered in nuclear transgenic plants. This disclosure  shows that a bacterial operon can be expressed in a single integration event  as opposed to multiple events requiring several years to accomplish. Expression of multiple genes via a single transformation event opens the possibility of expressing foreign pathways or pharmaceutical proteins involving multiple genes. Expressing the Cry2aA2 operon, including a putativ e chaperonin to aid in protein folding, in the chloroplast via a single transformation event leads to production of crystalized insecticidal protein s. Expressing the Mer operon via a single transformation event leads to a phytoremediation system.

Title: Cellular phone that exposes the user's brain to much less microwave radiation than ordinary cellular phones with the help of a proxy (intermediary) device
Inventor: MAYER YARON
IPC: H04R1/00
Filed: 2001-10-24
Abstract: Cellular phones are becoming more common and popular amongst all sectors of the population for business and private conversations, including many children, with about 500 Million users worldwide, and about 300,000 new joiners each day. There is much concern and there is already some accumulating evidence that the Microwave emission transmitted by the cellular antenna that is held close to user's head may have deleterious effects on the user, such as for example brain or eye cancer, and possibly even more so for children. One of the most common ways to try to avoid these problems has been the usage of personal earphones with microphone, but on 4/4/2000 it was published worldwide that a research conducted by the "Which" consumer Magazine in Britain found that in fact the earphone and its cable can act as an Antenna and also expose the user to the microwave radiation. The present invention solves the above problem in using earphones with cellular phones by a reverse and more sophisticated solution than short range wireless earphones, and also solves the problem that many people don t like using headsets at all.
