Title: Proteins involved in targeting of peptidyl transfer center, and corresponding therapeutic agents and methods
Inventor: DINMAN JONATHAN D
IPC: C12N15/11
Filed: 1996-10-04
Abstract: mRNA degradation is an important control point in the regulation of gene expression and has been shown to be linked to the process of translation. One clear example of this linkage is the observation that nonsense mutations accelerate the degradation of mRNAs. In this report we demonstrate that a subset of the mof alleles (maintenance of frame) in yeast, which were isolated as chromosomal mutations that increased the frameshifting efficiency at the L-A virus frameshift site and caused loss of the L-A satellite virus M1, also affect the nonsense-mediated mRNA decay pathway. The levels of nonsense-containing mRNAs were elevated in cells harboring the mof4-1 alleles.  Furthermore, mof4-1 is allelic to UPF1, which has been demonstrated to be involved in the nonsense-mediated mRNA decay pathway. Although cells harboring the mof4-1 allele lose the M1 virus, the other f alleles (i.e., upf1, upf2 and upf3) involved in nonsense-mediated mRNA decay maintain M1. The ifs1 and ifs2 alleles previously identified as mutations that enhance frameshifting at the -1 ribosomal frameshift signal from the mouse mannary tumor virus were shown to be allelic to the UPF2 and UPF1 genes, respectively, and both ifs strains maintained M1. The mof4-1 strain is more sensitive to the aminoglycoside paromomycin than a upf1.DELTA. strain, and frameshifting efficiency increases in a mof4-1 strain grown in the presence of paromomycin. These results indicate that the upf1p has a dual function in both translation and mRNA  turnover.

Patent CA-2244545-A1 (CA)
Inventor: OSMENT DAVID L
IPC: A63H19/36
Filed: 1998-07-30
Abstract: A structure is provided for creating an elevated subroadbed for an artificial landscape. The structure includes a flexible riser section of a given length that has a generally planar bottom. The riser section also has a generally planar top extending and supported parallel to the bottom so that the height of the section is consistent along its entire length. The riser is provided with first and second side walls, which each have a series of channels that extend into the riser in spaced apart relation. The channels allow the riser to be positioned in a radius. The top forms an elevated surface that enables low- lying areas to be more easily created on the artificial landscape below the elevated surface. A flexible incline section is also provided for creating a roadbed for an artificial landscape. The incline section has a top that extends at an angle relative to its bottom so that the section increases in elevation from one end to the other. Further, the incline section has channels formed therein which allow it to be flexed in either direction. A first flexible incline section may be provided that rises from a base to a higher elevation. A second incline section is provided which starts from the highest elevation of the first section and further increases in elevation. The second incline section and the first section can be placed in abutting relationship to form a roadbed having a continuous grade. Subsequent sections may be provided which further increase the elevation achieved.

Patent CA-2249132-A1 (CA)
Title: Method of simulating a photographic camera
Inventor: RIOUX MARC
IPC: G06T15/00
Filed: 1998-10-01
Abstract: Simulating a photographic camera for rendering two-dimensional images of virtual three-dimensional objects enhances flexibility and ease of use of a rendering system.  Simulating a photographic camera is performed by determining light from virtual light sources that passes through a lens of the simulated photographic camera having an aperture, focus, and shutter speed and is incident upon the imaging plane within the camera. The method also has application in teaching photography because, in some instances, computer simulation reduces the cost of equipment and consumables.

Title: Boot with insertable bushing
Inventor: ZORIC GEORGE
IPC: F16D3/84
Filed: 1999-02-23
Abstract: An automotive boot for use with a connection such as a constant velocity joint includes a separate boot and a separate bushing. The bushing has an internal configuration which is tri-lobed to contact the surface of one of the mechanical components encapsulated by the boot.   The internal surface of the skirt of the boot and the corresponding external surface of the bushing each contain interlocking components, preferentially these are ribs and corresponding grooves. The bushing is slightly larger than the boot to produce an interference fit and the ribs are slightly radially longer than the grooves are deep to deform the ribs when received in the grooves, thereby retaining the bushing without tightening the typical hose clamp and providing an effective seal between the bushing and boot to retain lubricants within the boot in use.

IPC: H04W4/00
Filed: 1999-03-17
Abstract: A system and method for recovering from a lost connection between a mobile station and a mobile communications system after a traffic channel has been successfully assigned are provided. After the connection is lost, rather than dropping the call altogether, the party on the other end of the call is connected to an announcement. While the announcement is playing, the system pages the mobile station in an effort to re-locate it and re-establish a traffic channel. When a traffic channel is successfully re-established, the call is connected. The connection may be lost during handoff, conversation (normal use), mobile termination or mobile origination for example.

Filed: 1998-07-29
Abstract: An improved cable tie dispensing apparatus includes a cutting and feeding apparatus which advances and severs a cable tie from an elongate strip of cable ties for delivery to an automatic cable tie installation tool. The cutting and feeding apparatus provides an elongate platform for supporting a cable tie strip therealong and a severing location adjacent one end of the platform which is defined to support one cable tie. An alignment pilot is supported adjacent the severing location and is movable towards the severing location so as to separate the supported cable tie from the strip to which it is connected. The alignment pilot includes a punch for severing the web between adjacent cable ties upon movement of the pilot toward the severing location. A firing chamber is included which has an open face for insertion of a single cable tie therein. The open face is sealably closed by movement of the pilot toward the severing location. In this manner, a single cable tie is separated from the web and almost instantaneously positioned for delivery to an installation tool.
