Title: Hole saw guide clamp system
Inventor: COOPER MICHAEL S
IPC: B25B7/02
Filed: 1997-01-15
Abstract: A system and method are provided for using a portable tool for assisting the making of holes in installed pipes, e.g., as water pipes and the like, to prepare for interconnected piping. Such system includes a hollow, cylindrical hole-saw guide, having an axis, for guiding the hole-saw while the hole-saw is making a hole in only the first side of the hollow installed pipe. The tool is constructed and arranged to maintain user-selected relative positions between the hollow installed pipe and the hole-saw while the hole-saw is making the hole in only the first side of the hollow installed pipe. A first fixed clamp-head is provided for positioning the hollow, cylindrical hole-saw guide adjacent the first side of the hollow installed pipe. A second movable and swivelable clamp-head is provided for holding a second side, opposed to the first side, of the hollow installed pipe in such manner as to have the centre line of the hollow installed pipe intersect the axis of the hollow cylindrical hole-saw guide. The second movable and swivelable clamp-head includes a V-shaped member solid which is closed along the axis of the hollow cylindrical hole-saw guide. A grip is provided for adjusting and positioning the first and second clamp-heads into a user-selected clamping position about the hollow installed pipe. The hole saw guide is preferably contained in a clamp-head at the end of the fixed jaw of a VICE-GRIP .TM. -like device. Such clamp-head accommodates various sizes of guide bushings and hole-saws for making various size holes in various size pipes. Other features assist accurate hole positioning, e.g., horizontal and vertical levels, centre marks, and V-shaped holding surfaces on the clamp-heads.

Title: Sequence analysis of saccharide material
Inventor: TURNBULL JEREMY EWAN
IPC: G01N33/50
Filed: 1995-10-30
Abstract: In a method of analysing saccharide material such as glycosaminoglycans (GAG's) to determine the sequence of monosaccharide units in oligosaccharide chains thereof, the saccharide chains are end referenced, e.g. by labelling or tagging at their reducing ends, and the saccharide material is subjected to a controlled partial depolymerisation using a selective scission reagent, for example low pH nitrous acid, which cleaves internal glycosidic linkages in accordance with a known linkage specificity so as to produce a mixed set of saccharide chain fragments having different lengths ranging throughout the full spectrum of possible lengths for the particular glycosidic linkage specificity of the selective scission reagent employed. Samples of the mixed set of saccharide chain fragments are then treated with selected exoenzymes including exoglycosidases that cleave only particular glycosidic linkages at the non-reducing end of saccharide chains and exosulphatases that selectively remove sulphate groups from monosaccharide residues at the non-reducing end of saccharide chains. These exoenzymes are applied to the samples either singly or in combination in accordance with a predetermined strategy. The treated samples are then analysed, conveniently by polyacrylamide gel electrophoresis (PAGE) to detect the chain fragments present which have a reducing end derived from the reducing end of the corresponding chain in the original saccharide material. Using PAGE, preferably gradient PAGE, the different samples are run in parallel tracks of the gel and a migration banding pattern is obtained that provides information which enables the monosaccharide sequence in the original saccharide material to be deduced.

Patent CA-2212335-A1 (CA)
IPC: B66F11/04
Filed: 1997-09-11
Abstract: A device for supporting and rotating a personnel platform with respect to a fixed attachment point comprises three main structural members, two of which are brackets which are attached through a vertical hinge point to two separate hinge points on the third member, a means of locking one bracket or the other to the intermediate member, and a means of rotating one bracket with respect to the other. Onto one bracket is fixed a personnel platform and the other bracket is connected to a fixed attachment point. The securing of either one or the other brackets to the intermediate member allows a minimum of 90° rotation in either direction from the neutral position of the platform using one and the same rotating means. This produces a support that fits into a relatively compact space between the fixed attachment point and the platform, and can be positioned to more easily avoid interference with possible other nearby attachments.

Filed: 1997-09-24
Abstract: In order to improve a transcoder unit (TRCU) for use in a telecommunications network in such a way that digital voice signals can be transmitted at different transcoding rates, it is proposed to dispose at least two arithmetic units (FR; HR, EFR) with different transcoding rates on respective plug-in circuit boards in the transcoder unit, and to provide the transcoder unit with a subrack with backpanel wiring which receives these plug-in circuit boards.  In this manner, arithmetic units each containing eight digital signal processors, for example, are provided for each of the different transcoding rates.  The arithmetic unit can be optimized for each transcoding rate.  Individual plug-in circuit boards can be replaced or added as supplements.  The transcoder unit (TRCU) is modular in construction and can be assembled or converted very flexibly, e.g., in the manner of a backplane system. The transcoder unit is used, for example, in a wireless telecommunications network, i.e., in a mobile radio network.
