Patent CA-2114494-A1 (CA)
Inventor: WINTEROWD JACK G
IPC: B27N7/00
Filed: 1994-01-28
Abstract: A method of producing a surfaced composite panel of cellulosic particulates, such as wood flakes, involves the application of polymer forming foamable material to at least one of the first and second major surfaces of the panel, contacting said at least one of the first and second surfaces with a pressure applying surface to apply pressure thereto, foaming the polymer forming foamable material while pressure is applied and curing the applied foam material to produce a polymeric coating on the panel with the desired surface, which is typically extremely smooth. One or both surfaces may be surface treated in this manner. A skin formed on the surface of the panel is believed to add to the strength and stiffness of the coating on the panel. A wide variety of foaming systems may be used to accomplish this surface treating. By avoiding sanding the surface treated panel, the skin remains intact. The resulting panel, in addition to being extremely smooth as desired, resists water penetration when subjected to water or high humidity conditions. The resulting panel is receptive to adhesives for purposes of securing overlaying materials such as vinyl, reduces formaldehyde emissions when a panel formed of the resin which emits formaldehydes is surface treated.

Patent CA-2117583-A1 (CA)
Title: Modified nucleotides
Inventor: HACES ALBERTO
IPC: C07H19/10
Filed: 1993-03-17
Abstract: The present invention provides novel modified nucleotide compounds having the general formula: X-n(J)-(d or r)NTP where N is adenosine, guanosine or cytidine; X is H, a fluorophore, a chromophore, a luminescent compound, a ligand or a hapten; n is an integer of 7 or more; and J is a Jeffamine (TM Texaco, Inc.) substituent.  These compounds are substantially superior substrates for incorporating label into nucleic acids during enzyme-catalyzed synthesis. Use of a Jeffamine-linked labelled nucleotide derivative as a partial substitute for unlabelled substrate therefore leads to significantly greater incorporation, hence increased label density per unit length of nucleic acid, than the same label joined by a prior art linker. Jeffamine-modified ribo- or deoxyribo-nucleotides are also provided for synthesis of Jeffamine-modified nucleic acids. The invention further provides an improved method of synthesizing labelled nucleic acids. This method provides greater frequency and higher efficiency of label incorporation, thus requiring lower amounts of nucleotide derivative in the reaction mixture.

Patent CA-2121748-A1 (CA)
Inventor: NICOLAI NORBERT
IPC: B29C55/02
Filed: 1994-04-20
Abstract: A process to increase resistance to tearing in a heat-resettable material is described, followed by extruding a polymer of a specified crosslinking density to produce a plastic web. After cooling the plastic web is heated by creating a  temperature  decreasing  towards  its  core  and stretched at  core  temperature below crystalline melting temperature of partially crystalline and crystalline polymers resulting in a distribution of orientation over the full section of the plastic web. Resistance to tearing will be essentially increased in this manner based on a simple, low-cost production process.

Abstract: A reactor for conducting a continuous multi-phase catalytic reaction such as the conversion of syngas to higher hydrocarbon fuels. Gaseous reactants are introduced via a gas-permeable plate (15) into a slurry {16) which includes the product and a finely divided catalyst. The liquid product is separated from the remainder of the slurry by means of a filter unit (13) including a filter member (22). A pressure differential is established across the fitter member (22) by means of a constant level device (23) within the filter unit which maintains a level of filtrate (32) within the filter unit (22) below the level of the slurry (16). The slurry (16) is maintained in a constant state of agitation by the introduction of the gaseous components as a steam of bubbles. Fluctuations in the pressure differential across the filter member (22) prevent the filter member from clogging and the gas spaces (28, 29) above the filtrate (32) and the slurry (16) are in communication.

Title: Method of input signal resolution for actively redundant process control computers
Inventor: BACA ELOY JR
IPC: G06F11/20
Filed: 1993-06-16
Abstract: A method of input signal resolution in a process control system where each of the actively redundant process control computers per-forms a common arbitration process on corresponding input signals. Blocks of corresponding input signals are mutually exchanged by the actively redundant process control computers, and an initial check is made to determine if these input signals are valid. For input signals re-presenting valid analog values, a determination is made as to whether a predefined tolerance has been exceeded between corresponding input signals in the present process control cycle. When the predefined toler-ance has been exceeded, then a check will be made to determine the predefined tolerance was also exceeded in the last process control cy-cle. If the predefined tolerance was not exceeded in the last process control cycle, then the analog input value selected during the last pro-cess control cycle will be employed in the present process control cycle. If the predefined tolerance was exceeded in both the present and the last process control cycle, then a predetermined magnitude criteria will be used to select the analog input value for use in making process con-trol decisions. An indication will also be provided in each of the active-ly redundant process control computers to identify which of the corre-sponding input signals were selected by that process control computer.
Patent CA-2140061-A1 (CA)
Inventor: GERSHEN BERNARD J
IPC: H02M5/257
Filed: 1995-01-12
Abstract: The present invention teaches a dimmer which incorporates an alternating current (AC) trigger which exhibits asymmetrical electrical characteristics. This eliminates the undesirable snap on hysteresis effect associated with conventional dimmers utilizing symmetrical AC triggers such as discs and silicon bilateral switches (SBS). One embodiment of the present invention utilizes a zener diode to create the asymmetry. During one polarity of the AC source, the breakover voltage of the trigger is increased, forcing the trigger to breakover at a time later in the AC cycle than it would otherwise have with a symmetric trigger. This compensates for charge dumping of the phase control capacitor into the gate of the triac which would otherwise cause the snap on hysteresis effect.

Title: Thermal polymerization of dicyclopentadiene
Inventor: WILLIAMS THEODORE J
IPC: C09D11/10
Filed: 1995-01-19
Abstract: The specification discloses a method for making DCPD based resins that have relatively narrow molecular weight distributions. The method comprises thermally polymerizing dicyclopentadiene monomer in the presence of one or more strong acids, preferably with an olefinic modifier, to provide a dicyclopentadiene oligomer. Optionally, an organic sulfur species can also be used to further effect molecular weight control. For end-use performance in inks, adhesives, coatings and other related areas, the invention provides dicyclopentadiene oligomer resins having weight average molecular weights less than 1000 and relatively narrow molecular weight distributions, as measured by a polydispersity index, of less than about 2.3. Among the strong acids that are effective for controlling molecular weight, hypophosphorous acid is preferred because it gives light colored resins.

IPC: H01R13/64
Filed: 1995-01-25
Abstract: The socket has a housing, an outer sleeve on the housing centered on an axis and having an axially extending and radially inwardly open groove. A latching element in the housing in axial alignment with the groove is displaceable axially relative to the outer sleeve. A spring or other biasing unit is braced between the element and the housing for urging the element into an outer position and a mechanical coupling between the latching element and the switch prevents a switch on the housing the switch from moving from its the position to its on position except when the element is in an inner position. A nonmatching plug has a body formed with a radially outwardly open recess and respective contacts in the body are engageable with contacts of the outer sleeve. A tubular adapter body is fittable over the plug body and inside the outer sleeve in an inserted position with the plug contacts engaging the socket contacts.      A radially outwardly projecting bump on the tubular body engages the latch element to hold same in the inner position in the inserted position, and a retaining element on the outer sleeve projects radially inward into the recess of the plug body and bears radially outward against the outer sleeve only in the inserted position so that in the inserted position the bump holds the element in the inner position and the retaining element locks the adapter and plug in the outer sleeve.
