Patent CA-2186273-C (CA)
Inventor: SHU ZHI X
IPC: H01M10/26
Filed: 1996-09-19
Granted: 2003-07-01
Abstract: A conventional electrolyte for a secondary cell having a carbonaceous anode is comprised of an alkali metal salt  dissolved   in  an  organic  electrolyte  solvent. Intercalation   and   de-intercalation   during   repeated discharge/charge  cycles  of  the  secondary  cell  using  a conventional electrolyte solvent causes continual exposure of  bare  surfaces  of  the  carbonaceous  material  to  the electrolyte,   resulting   in   continual   consumption   of electrolyte in the formation of new passivation films on the bared or partially covered surfaces, adversely affecting the performance and capacity of the cell.   In accordance with the  present  invention,  the  organic  electrolyte  solvent comprises chloroethylene carbonate, propylene carbonate and ethylene carbonate.  The chloroethylene carbonate is capable of forming a very stable passivation film on the anode.  The performance and capacity of the secondary cell is improved substantially by the addition of the halogenated organic solvent.

Title: Colour image generation systems and applications
Inventor: RASCH ANDREAS
IPC: G02B30/25
Filed: 1996-02-06
Granted: 2000-10-17
Abstract: The invention concerns colour image formation systems for displaying real or virtual, two-dimensional or three-dimensional, colour or monochrome images, and the use thereof, in particular for television and video or printing applications. The basic concept of one variant printing applications. The basic concept of one variant (a) is the use of a "unit for three-dimensional beam combination" (14) for combining three light components of different wavelengths in the visible spectrum and the diffraction of the light (LVM) thus combined in such a way as to create, by intensity or amplitude modulation and colour modulation of the light components carried out synchronously with the diffraction of the combined light (LVM), a virtual image in space or a real image on a projection screen (5) which can be perceived by the eye (12) of the observer. The "unit for three-dimensional beam combination" (14) comprises waveguides (2, 9) capable, with more or less equal effectiveness, of broad-band or spectrally selective transmission and three-dimensional combination of light. All electronic and optical assemblies for the colour image formation can be integrated on a substrate (11) in either monolithic or hybrid form. The colour picture formation system can be realised in the form of a module enclosed in a housing.

Abstract: A collapsible pump chamber (60) is provided which includes several functional elements of a pump device. For example, the collapsible pump chamber (60) may be a bellows which includes a functional element of an outlet valve (80), a functional element of a biasing feature, and a functional element of a spin chamber. Consequently, functional elements of all of the downstream functions are incorporated into the bellows. This can significantly reduce costs; due to reduced tooling, and assembly, for example. Dunnage means (51) is provided for occupying volume within the collapsible pump chamber (60) to improve pump priming. The dunnage means (51) may be free floating or associated with the inlet valve (50). A process is provided for severing the functional element of the outlet valve (80), the functional element of the biaising feature, and the functional element of a spin chamber from the collapsible pump chamber (60) during assembly.

Title: Coupling device for locking an excavation tooth onto an adaptor
Inventor: ADAMIC DWIGHT
IPC: E02F9/28
Filed: 1997-11-13
Granted: 2001-09-04
Abstract: The present invention is a coupling device for locking an excavation tooth onto an adaptor. The adaptor and tooth have a passage extending therethrough. The device includes a pin and retainer. The pin is shaped in such a manner as to improve its resiliency and its ability to be disengaged from the retainer to remove the tooth from the adaptor.      The retainer is inserted into the adaptor. The pin includes a retainer seat for engaging the retainer. The retainer seat has a front wall perpendicular to the longitudinal axis of the passage and a back wall which slopes away from the front wall. As the pin is inserted into the passage, the retainer engages the pin until it enters the seat. The front wall then prevents the pin from being retracted from the passage. To remove the pin, force is applied to the driven end of the pin. The pin will continue through the passage while the retainer slides along the sloped back wall of the retainer seat. This arrangement allows for the easy insertion and removal of the pin with a relatively small amount of force.

Title: A system for transmitting electric power
Inventor: SVENSSON KJELL
IPC: H02J5/00
Filed: 1997-11-13
Granted: 2001-05-08
Abstract: A system for transmitting power over a direct voltage network. A first power station connects one alternating voltage network to the direct voltage network. The first power station includes a converter for bidirectionally transferring power between the direct voltage network and the alternating voltage network. The converter maintains constant value of voltage on the network, or operates in a second alternative mode of controlling constant current between the alternating voltage network and the direct voltage network. When the voltage on the direct voltage network drops below a reference value, a second power station connected to the direct voltage network and to a remaining alternating voltage network takes over the voltage regulation function. The second power station prior to taking over the voltage regulating function was in a current regulating function. In this way, when the first station reaches its limits of voltage regulation, the second station is enabled to take over the voltage regulating function switching out of a current regulating function.
