Patent CA-2204558-A1 (CA)
Inventor: ZULKOSKI BLAINE R
IPC: E04B1/16
Filed: 1997-05-06
Abstract: In one basic form, the invention discloses a system with associated methods of providing a flexible and economical modular system for use as a container-form for building structures from typically light weight expandable foam, such as expandable polystyrene foam. The invention includes molding a component portion with spacers, then fabricating a module by coupling the various portions, such as wall components, to a variable spacing, yet with sufficient strength to withstand the rigors of such applications as the pouring of concrete structural walls. The module may cooperate with other modules to form a modular form. This spacing may be accomplished by either molding, trimming, removing or otherwise providing a certain length to the spacers in an area of the spacers nominated a variable length removable section. The spacers may also have a tapered centering configuration to assist in located reinforcing materials. The invention also describes the use of the container-form systems with structural walls to form, for instance, preformed walls, an insulated firewall system, a structural wall with a fitting formed integral with the wall, and other like uses and applications. The walls may even be semi-prefinished and may include attaching a foam form for insulation. Thus, a preformed insulating structural wall with finish surfaces could be made in a facility, hauled to a job site, quickly erected, and with minimal finishing, the walls completed. The finish surfaces could be connected to either the wall component, the structural wall member, or both and may be on one or both sides.

Title: Vectors for tissue-specific replication
Inventor: CHIANG YAWEN L
IPC: A61K35/76
Filed: 1995-11-28
Abstract: The invention generally relates to targeted gene therapy using recombinant vectors and particularly adenovirus vectors. The invention specifically relates to replication-conditional vectors and methods for using them. Such vectors are able to selectively replicate in a target tissue to provide a therapeutic benefit from the presence of the vector per se or from heterologous gene products expressed from the vector and distributed throughout the tissue. In such vectors, a gene essential for replication is placed under the control of a heterologous tissue-specific transcriptional regulatory sequence. Thus, replication is conditioned on the presence of a factor(s) that induces transcription or the absence of a factor(s) that ihibits transcription of the gene by means of the transcriptional regulatory sequence with this vector, therefore, a target tissue can be selectively treated.

Inventor: PASANEN KARI
IPC: G06F11/00
Filed: 1996-10-29
Abstract: In process controlling computers, such as switching exchanges, faults may prove to be very expensive. Particularly hard to solve are software defects. If problems occur, it is important that maintenance can be directed at the correct target as soon as possible. A threat is constituted by vandals and hackers. If the option for maintaining from elsewhere is incorporated in computers, the danger for misuse consequently increases. Prior art techniques for detecting memory problems do not necessarily reveal defects occurring at regular intervals caused by the method of calculation. Memory defects will occur at regular intervals e.g., if an address line of a memory circuit becomes faulty. A second drawback of the prior art is that the checksum has to be calculated anew if the contents of just one storage location change. The method of detecting memory problems according to the invention is "regularly irregular" so that it detects in a reliable manner an uncontrolled change in any storage area (MA). Furthermore, the checksum (CS) calculated according to the method may be updated upon changes of an element in a storage area (MA) so that the updating requires much less calculation than would calculating the checksum over the entire storage area (MA) being monitored. The method is applicable in detecting hardware and software defects and in expediting the restart of a computer.

Abstract: A nozzle assembly for use in injection molding comprises a pair of spacers acting between the manifold and either a cover plate or a hot runner plate of an injection molding machine to apply a contact pressure between the nozzle body melt channel and the manifold melt channel to achieve a seal therebetween. The resilience of the spacers result in an increased operational temperature range for the nozzle assembly, the contact pressure being generated and/or maintained over the range of the operational temperatures. An additional advantage is provided in that the nozzle assembly is compact and can be closely spaced with similar nozzle assemblies to achieve center spacings as small as eight millimeters. The assemblies can be mounted and/or removed from the cavity of the manifold plate, and/or changing of the nozzle heater elements, without requiring removal of the mold from the injection mold machine. In one embodiment, the nozzle assemblies can be removed or mounted by removing a cover plate from the manifold plate, the cover plate being capable of retaining multiple nozzle assemblies in place. In another embodiment, the nozzle assembly has a mounting flange and one or more bolts extend through the and engage the manifold plate and these bolts allow mounting and removal of the nozzle assembly.

Filed: 1998-07-16
Abstract: Synchronizing local timing units to a central timing unit to determine the difference in timing between external links and the local timing units so as to synchronize the centralized timing unit to the external links. This difference in timing is then transmitted to the central timing unit, which utilizes this information to adjust the timing of the central timingunit. The adjustment to the central timing unit brings it into synchronization with the selected external link. The local timing units are synchronized to the central timing unit via multiple timing paths set up through switching units within the network. Each switching unit switches one bit of data for each group of data being received on each of the external links. In addition, information received by each of the external links designating the accuracy of the external link is transmitted to the central timing unit so that the central timing unit can select the external link having the highest accuracy.
