Patent CA-2339430-A1 (CA)
Title: Hammer
Inventor: HANKE ANDREAS
IPC: B25D17/08
Filed: 2001-03-07
Abstract: A hammer is provided which enables the orientation of a tool or bit mounted within a tool holder (spindle) of the hammer to be rotated to the required orientation.  The hammer comprises a housing part (1) having an aperture therein in which a spindle (2) that is mounted so that the spindle (2) extends out of the housing through the aperture. The spindle (2) is capable of being rotated about its axis to any of a plurality of orientations, so as to alter the orientation of a tool or bit mounted therein. A locking ring (4) is located around the spindle (2) which locking ring can be moved axially along the spindle at least to a limited extend into and out of engagement with the aperture of the housing part (1), but cannot rotate about the spindle (2), so that when the locking ring (4) engages the aperture, it prevents the spindle (2) from rotating with respect to the housing (1). A grip ring (12) is located around the spindle (2) and can be rotated about the axis of the spindle from a normal operating position in which it prevents disengagement of the locking ring (4) from the aperture in the housing. When the grip ring (12) is rotated about the axis of the spindle (12) by the operator of the hammer to a second position, the locking ring (4) is disengaged from the aperture of the housing (1), thereby to allow the spindle (2) to rotate with respect to the housing (1) to a different orientation. Thus, it is possible to form a hammer in which the orientation of the bit can be changed in a particularly simple manner: the operator simply rotates the grip ring (12) to a position in which the spindle lock is released, or at least can be released, and then rotates the grip ring further, to thereby rotate the spindle (2), until the tool or bit is in the correct orientation.

Patent CA-2361804-A1 (CA)
Title: Creasing device
Inventor: HARRIS GRAHAM
IPC: B65H45/30
Filed: 2000-02-17
Abstract: The invention is a creasing device for creasing paper or card before it is folded.  The device consists of a drum-shaped male component (2) featuring grooves (8, 10, 12) of various widths and depths to hold rubber O-rings (24, 26, 28). A female component (4) is almost identical to the male component (2) but has receiving grooves (14, 16, 18) that are slightly wider and deeper. When fixed to top and bottom shafts with one O-ring (24, 26, 28) in a groove (8, 10, 12) on the male component (2) aligned with a receiving groove (14, 16, 18) of the female component (4), a sheet of paper fed between the drums will be creased by the pressure of the O-ring (24, 26, 28) forcing the paper into the receiving groove (14, 16, 18). The invention allows the device to be quickly and easily set up to form creases of various widths and depths, while the resilient O-rings minimize damage to the paper.

Title: Hydrogen peroxide indicator employing enzyme and dye
Inventor: MORRISON TODD
IPC: C12Q1/28
Filed: 2001-12-21
Abstract: A method for determining exposure of a test sample to hydrogen peroxide in an atmosphere includes placing a substrate into the atmosphere, contacting the substrate with the hydrogen peroxide, reacting the hydrogen peroxide with a dye intermediate to produce a chromophore indicative of the integrated exposure of hydrogen peroxide in the atmosphere; and correlating the chromophore to the integrated exposure of hydrogen peroxide in the atmosphere. The dye intermediate may be a dye-couple of 3-methyl-2-benzothiazolinone hydrazone hydrochloride (MBTH) and 3-dimethylaminobenzoic acid (DMAB).

Patent CA-2369828-A1 (CA)
Title: Microbicidal formulations and methods for controlling microorganisms
Inventor: BATARSEH KAREEM
IPC: A01N47/44
Filed: 2000-04-19
Abstract: Microbicidal formulations are described which are preferably ecologically friendly and non-toxic to mammals, and are highly effective against a broad spectrum of detrimental pathogenic microorganisms. The microbicidal formulation contains complexes having the formula R-M, wherein R is at least  one organic chelating moiety and M is at least one metal ion which is microbicidal to at least one microorganism. These complexes can disrupt microorganism activities by penetrating the natural protecting bio-films of such microorganisms through the reaction of the R-group with the organic constituents of these microorganisms while releasing M into their intra- cellular media. Thus, this process exhibits its biocidal activities from the  inside-out, contrary to other methods which rely on damaging the protective biofilms. These microbicidal formulations can be diluted in suitable proportions into aqueous systems to produce the desired dosages for each individual case, depending on the level and the severity of the contaminatio n. The microbicidal formulations can be applied by conventional methods, e.g., spraying, soaking, fogging, impregnation, and the like.

The saddle elements (10) may be used in a structure (60) which includes four flip-flopped stacked elements (10).
Patent CA-2377782-A1 (CA)
Inventor: THOMAS GARETH
IPC: C21D1/22
Filed: 2000-03-28
Abstract: Alloy steels that combine high strength and toughness with high corrosion resistance are achieved by a dislocated lath microstructure, in which dislocated martensite laths that are substantially free of twinning alternate with thin films of retained austenite, with an absence of autotempered carbides, nitrides and carbonitrides in both the dislocated martensite laths and the retained austenite films. This microstructure is achieved by selecting an alloy composition whose martensite start temperature is 350 °C or greater, and by selecting a cooling regime from the austenite phase through the martensite transition region that avoids regions in which autotempering occurs.

Title: Method and system for measuring the relief of an object
Inventor: CANTIN MICHEL
IPC: G01B11/25
Filed: 2000-07-14
Abstract: A method and a system for measuring the relief of an object are described herein. The system includes a grid projecting for projecting a grid, an image acquisition apparatus that includes a camera, and a computer. Providing a reference object having common elements with the object to measure, the method includes the steps of a) positioning the grid at three different known positions relative to the camera and the common elements; b) for each position of the grid, projecting the grid unto the reference object and, with the camera, taking an image of the reference object to yield three images having values for each pixel of the camera and c) computing the reference object phase for each pixel using the three reference object intensity values for the corresponding pixel. Steps a), b) and c) are repeated by replacing the reference object by the object to be measured. The difference of height between the object to be measured and the reference object for each pixel are then computed by subtracting the reference object phase and the object phase for the corresponding pixel.

Title: Novel strategy for carbohydrate-based therapeutic vaccines
Inventor: LIU TIANMIN
IPC: A61K39/095
Filed: 2000-07-28
Abstract: The sialic acid component of a sialic acid unit-containing cell surface marker characteristic of cancerous mammalian cells, such as .alpha.2-8 polysialic acid, is modified, so that cells normally expressing such a marker express instead a modified sialic acid unit-containing cell surface marker which is strongly immunogenic. For example, the present invention enables, in a portion of patient cells which regularly express .alpha.2-8 polysialic acid (i.e.  various types of cancer cells), the expression of a highly immunogenic surface antigen namely, modified .alpha.2-8 polysialic acid. The modification is suitably N-acylation of a precursor of the sialic acid, so that the N-acylated precursor becomes chemically incorporated in the polysialic acid during its intracellular biochemical synthesis. Antibodies specific for the modified antigen, which can be induced using a conjugate of a suitable portion of the modified sialic acid unit-containing marker (such as .alpha.2-8 polysialic acid) and a protein, can then be used to eliminate cells which express .alpha.2-8 polysialic acid. Vaccines can be prepared utilizing conjugates of the modified sialic acid-containing marker, or utilizing antibodies produced in response to exposure of a suitable subject to the modified sialic acid-containing marker, for managing cancer conditions which involve cancer cells characterized, at least in part, by expression of modified sialic acid unit containing marker.
