Patent CA-2433701-A1 (CA)
Inventor: COSLOVI ILARIO A
IPC: B61F5/16
Filed: 2003-06-27
Abstract: A railroad car body has a longitudinally extending center sill, and a main bolster extending transversely relative to the center sill. A center plate is mounted under the center sill at the intersection of the center sill and the main bolster. The center plate seats in the center plate bowl of a truck that supports the rail road car body for rolling motion along the rail road tracks. The center plate is a casting that has a round peripheral wall that seats entirely within the center plate bowl. None of the center plate extends beyond the round peripheral wall, and none of the center plate overhangs the peripheral upstanding steel ring of the center plate bowl wall. The center plate has a continuous circumferential welding fillet relief such as may tend more easily to permit automated welding. The center plate has a hollow, upstanding truncated central cone member for accommodating a king pin. The truncated cone stands taller than the rim. A  keying fitting is mounted adjacent to the central cone to discourage angular mis-orientation of the lateral center plate edge reliefs.

Title: Cartridge shell and cartridge for blast holes and method of use
Inventor: ROGERS NIGEL
IPC: F42D3/04
Filed: 2001-02-22
Abstract: Cartridge (10c) comprises body (12) defining a volume for holding energetic material. Body (12) has a first end (16) located adjacenta toe (48) of hole (46) formed in hard material (47), and a second end (18) directed towards collar (50) of hole (46). End (18) is tapered to form a point or wedge-like member. Stemming material (52) is placed in hole (46) to a level below free face (54) of hard material (47) and mechanically held in place by stemming bar (56). When the energetic material is initiated, gas pressure forces cartridge (10c) towards collar (50). As this occurs, the point acts to increase the radial compressive force on stemming material (52) in the annular region between end (18) and the adjacent portion of hole (46). This increases the sealing effect of stemming material (52) and maintains constant the volume in hole (46) within which the gas operates.

Title: Method for the determination of telomere length
Inventor: BAIRD DUNCAN MARTIN
IPC: C12Q1/68
Filed: 2002-06-21
Abstract: A method is described for determining telomere length of mammalian chromosom al DNA, which method comprises the steps: (a) annealing the 3' end of a single- stranded oligonucleotide (hereinafter referred to as a 'telorette') to a single-stranded overhang of the telomere comprising the G-rich telomere stra nd (comprising TTAGGG repeat sequences) and covalently binding the telorette to the 5' end of the C-rich telomeric strand (having CCCTAA repeat sequences) thereby forming a ligation product; (b) amplifying the ligation product form ed in step (a) to form a primer extension product; and (c) detecting the length of the primer extension product(s) of step (b). Step (b) is preferably carri ed out by PCR using: (i) a first primer capable of annealing to a telomere- adjacent region of DNA but which first primer is not capable of annealing to the C-rich telomeric repeat sequence (CCCTAA); and (ii) a second primer (hereinafter referred to as a 'teltail' primer) identical to the 5' end sequence of the telorette of step (a) which amplification is effected under conditions such that the first primer hybridises to the C-rich telomeric strand (comprising the CCCTAA repeats) and is extended to form a first prime r extension product; and the teltail primer hybridises to the first primer extension product and is extended to form a second primer extension product. Also described are specific primers, including telorettes and teltails, for carrying out the method; a kit for use in the method; and the use of the method in determining telomere length and assessing biological conditions associated therewith.
