Patent CA-2305883-A1 (CA)
Inventor: KAUFMANN GARRY CARL
IPC: G04B49/02
Filed: 2000-04-25
Abstract: A horizontal sundial constructed to accurately tell time at a specific latitude having female threads incorporated into both the north and south sides of the dial plate. Threadedly matched male gnomon angle-adjusting bolts serve to raise either the north or the south end of the dial plate and gnomon. This serves to bring the gnomon to the same angle with the horizontal as the latitude of intended use. The female threads can be located on the face of the dial plate to establish a simple mathematical relationship, such that a one degree change in gnomon elevation will correspond to a whole number of revolutions of the gnomon angle-adjusting bolts.

IPC: G02F1/1335
Filed: 1998-11-19
Abstract: Methods of and apparatuses for reducing the solar or infrared loading on display devices. A reflective material (39) is positioned between a radiant energy source (5) and the absorptive material (410) of a display device (400) to reflect wavelengths of radiant energy in the infrared or near-infrared range. The reflective material (30) allows visible radiant energy (60) to be transmitted, while reflecting the infrared radiant energy to reduce the infrared loading on the display device. The present invention reduces the temperature rise of the display device due to infrared loading by reflection rather than absorption of the radiant energy, while preserving the integrity of the visible wavelength range. The reflective material (30) reduces the infrared loading on the display device by up to 50 %.

Inventor: NDONG DANIEL
IPC: C12N15/82
Filed: 2000-10-27
Abstract: The present invention relates to engineering cells, tissues and organs, from animals or plants for low temperature, dehydration or salt tolerance by using a cold-regulated gene from cold-tolerant plants. The invention also relates to the method used to efficiently transform and generate stable transgenic strawberry plants. This method was efficient in producing a cold-tolerant strawberry using a gene from a cold tolerant species. The gene encodes a protein involved in protecting the cellular membrane against osmotic stress caused by freezing, salt, and dehydration. The gene product could be useful in protecting leaves flowers and fruit against these osmotic stresses. This will result in extending shelf life of these fresh produce. The invention also teach the use of cold-regulated genes or their products to protect different molecules, cells, tissues and organs during storage at low temperature.

Title: Usurpin, a mammalian ded-caspase homologue that precludes caspase-8 recruitment and activation by the cd-95 (fas, apo-1) receptor complex
Inventor: RASPER DITA M
IPC: C12N5/10
Filed: 1999-07-07
Abstract: The protein Usurpin, an endogenous mammalian regulator of the process of apoptotic cell suicide, is provided. Provided are three Usurpin proteins having an amino acid sequence selected from the group consisting of: SEQ.ID.NO.:4, SEQ.ID.NO.:5, and SEQ.ID.NO.:6 that arise from alternative splicing of the Usurpin gene. The full-length Usurpin polypeptide (Usurpin- .alpha.) has features in common with pro-caspase-8 and -10, including tandem  "death effector domains" (DEDs) on the N-terminus and a large subunit/small subunit caspase-like domain, but it lacks key residues that are necessary fo r caspase proteolytic activity. However, Usurpin heterodimerizes with pro- caspase-8 and precludes pro-caspase-8 recruitment by the FADD/MORT1 adapter protein, thus blocking an important interaction in the CD95 (Fas/APO-1) apoptotic process. Therefore, Usurpin is useful as a modulator of the sensitivity of cells to CD95 (Fas/APO-1)-mediated apoptosis. Accordingly, th e present invention also provides methods of modulating apoptosis by introduci ng Usurpin polypeptides into cells. Also provided are various purified nucleoti de sequences encoding Usurpin. Also provided are methods of identifying inhibitors of the interaction between Usurpin and pro-caspase-8. Such inhibitors will be useful in controlling the interaction between Usurpin and  pro-caspase-8, thus modulating apoptosis.

Title: Backscatter instrument for monitoring particulate levels in a gas stream
Inventor: ROSE THOMAS H
IPC: G01N15/00
Filed: 1999-06-11
Abstract: An automatic setup backscatter particulate monitor includes a small source (38) of narrow beam radiant energy directed into a gas stream containing particulates. A lens (34) that is mounted behind the radiant energy source (38) collects the energy reflected back from the particulates and concentrates it on a photodetector (48). The beam is directed into the duct at an angle greater than twice the beam spread, minimizing reflection off opposing wall surfaces. Internal radiant energy sources are periodically directed to the detector to verify system integrity. Backscattered energy is corrected for energy reflected from the opposite stack wall and for ambient energy.
