Patent CA-2267418-A1 (CA)
Inventor: HESCH ROLF
IPC: B27N3/14
Filed: 1997-09-16
Abstract: This invention concerns an economical way to use shives, previously considered to be waste material, in the production of building materials. To that effect, shives of bast fiber or plant origin are targetedly added to bast fiber and a bonding agent. The shives can contain fibers which are not completely released and remain naturally attached. These fibers project laterally from the shives in an irregular fashion and are between 2 mm and 100 mm long. The shives and the loose fibers and/or the shives with the non-completely released fibers are fed, after corresponding dispersion and dosage, into a coating device for liquid additives and/or into a scatter system for solid additives, and subsequently evacuated as fleece or cake, during which mechanical matting can be performed by air flow.

Title: Method for associating one directory number with two mobile stations within a mobile telecommunications network
Inventor: WESTBROOK BRET
IPC: H04W8/26
Filed: 1997-12-03
Abstract: A home location register (HLR) associated with a particular mobile subscription correlates two different international mobile subscriber identity (IMSI) numbers with a particular mobile subscriber integrated service digital network (MSISDN) number. When an incoming call connection is received towards that MSISDN number, the HLR makes a determination as to which one of the two mobile stations associated with the two IMSI numbers is active. The incoming call connection is then forwarded to the active mobile station. In case both mobile stations are active, the received incoming call connection is rerouted to the mobile station preassigned as a primary mobile station.

Patent CA-2285347-A1 (CA)
Inventor: DEMARCO ANTHONY THOMAS
IPC: H03G3/02
Filed: 1998-03-23
Abstract: A product and system are disclosed for intelligently controlling the number of amplifier modules that are active in a linear amplification system. By exercising such control, the system can avoid using unnecessary power. The invention monitors the system and gathers information from signals associated with the system, particularly information concerning signal power. A control functionality evaluates the gathered information to decide how many modules are necessary to sufficiently operate the amplification system or to decide if it has been commanded to perform certain functions. Once this decision is made, the control functionality communicates control signals to the power amplification modules to activate the needed or desired number of modules and deactivate the unneeded or undesired number of modules. Likewise, the control functionality configures the splitter and the combiner according to the number of needed or desired amplifier modules. This gathering, evaluation, and control are conducted continuously.

Inventor: GLEBE G TED
IPC: B63B17/00
Filed: 1999-12-06
Abstract: A universal adjustable platform providing a horizontal surface for mounting equipment on the inside of a boat hull is disclosed. The platform has a back plate mountable to the boat hull preferably near the gunwale. A support plate is pivotally attached to the back plate by matched lugs on each plate rotatably joined by pivot pins. A support arm is connected between the back and support plates forming a diagonal brace. The support arm is pivotally connected at each end to a respective plate via a lug and clevis arrangement. The support arm is formed by two elongated shafts arranged in a parallel, spaced apart relationship interfitting within a clamping block. The elongated shafts can slide within the block allowing the length of the support arm to be adjusted in response to adjustment of the relative angle between the support plate and the back plate. The clamping block is formed from two oppositely arranged side portions which are bolted together. When the bolts are tightened, the side portions clamp down on the elongated shafts and fix the length of the support arm thereby fixing the relative angle between the plates.

Filed: 1998-06-02
Abstract: A system for delivering a tooth whitening substance to a plurality of adjacent teeth, the delivery system comprising a strip of flexible material having a sufficient flexibility to form a curved shape on a plurality of adjacent teeth and a tooth whitening substance. The strip of material is readily conformable to the teeth surfaces and to interstitial tooth spaces without permanent deformation when the delivery system is placed thereagainst. The tooth whitening substance is applied to the strip of material such that when the delivery system is placed on the surface of the teeth, the substance contacts the surface providing an active onto the surface. The substance also provides adhesive attachment between the strip of material and the surface to hold the delivery system in place for a sufficient amount of time to allow the active to act upon the surface. The method of delivery includes pre-coating the strip of material or having the wearer apply substance to the strip of material and then applying the delivery system to the teeth surfaces.

Title: How to affect the chlorophyll biosynthesis in plants
Inventor: GRIMM BERNHARD
IPC: C12N9/90
Filed: 1997-11-18
Abstract: A gene encoding a hybrid protein consisting of ALA-S yeast and a N-terminal transit sequence for the small carboxydismutase sub-unit is introduced into the genim of tobacco (nicotania tabacum) and a chlorophyll-poor tobacco transformant which expresses glutamate-1-semialdehyde-transminase (GSA-AT) antisense RNA. The expression of ALA-S in the GSA-AT transgenic antisense strain has produced green co-transformants, the chlorophyll content of which is similar to that of the wild type, while the wild-type transformants have shown no phenotypical changes. The capacity of plants to synthetize ALA and chlorophyll is increased, thereby demonstrating the contribution of ALA-S to the ALA supply required for the chlorophyll synthesis. The transgenic plants produce chlorophyll in the presence of gabaculine, a GSA-AT inhibitor. The permanent RNA and protein content of GSA-AT have been reduced, as well has the enzymatic activity of plants expressing ALA-S. The additional synthesis of ALA  also explains the expression of GSA-AT in the C5 way.
