Patent CA-2424449-A1 (CA)
Title: Operating device
Inventor: WASCHGLER MICHAEL
IPC: E05B17/04
Filed: 2003-03-31
Abstract: An operating device for doors, windows, etc. comprises a rosette (20) for holding a rotating handle (10) whose head (12) contains a lock cylinder (18) with an axially displaceable locking bolt (44) that is axially spring-loaded and automatically assumes an engaging position at a defined angle of rotation of the handle (10) by sliding over a stepped locking sleeve (30) of the rosette (20). The lock cylinder (18) has a core (40) with a radial opening (50) in a non-rotating wall (58) for controlled movement of a spindle (48) that radially extends from the locking bolt (44) which engages the locking sleeve in defined angular positions of the handle (10). The opening (50) extends over a peripheral angle of e.g. 180° to 220°, and is a con-toured window having a lower flat segment (52), a depression (54) and a steeper segment (flank 56). On top, two straight edge sections (62, 66) run out at a vertical intermediate edge (58) above the depression (54), with lateral edges of the opening (50) forming stops for the spindle (48). If the key S is in the cylinder (18), pivoting the handle (10) from a horizontal position into an upward position (12 o'clock) requires two-hand operation. As the handle (10) is turned down into a transverse position (3 o'clock or 9 o'clock), the locking bolt (44) engages behind a tangential stop (68) under spring load, whether or not the key (S) is in the lock cylinder (18).

Abstract: A tool for housing and supplying bits by which they can be driven such as a screw driver or drill has a housing with an elongate tube extending through the housing along the axis to a forward presentation end of the tube at which the bits are presented for use. The housing has a rotatable storage holder mounted in the housing for holding and storing a plurality of tool bits and arranged by manual engagement with an exposed side portion to rotate about a second axis parallel to the tube. The rotatable holder has a plurality of receptacles each for receiving a respective one of the tool bits arranged parallel to the second axis and in angularly spaced relation around the second axis. The rotatable holder is manually rotated to cause each receptacle in turn to move to a position aligned with the tube where a plunger mounted within the tube is moved forward and rearward therein from a retracted position, in which a forward end of the plunger is retracted rearwardly of the holder, to a forward position adjacent the forward presentation end. The plunger has a flat magnetic bit carrying face at the forward end. The holder is rotatable in the housing when the plunger is moved to the retracted position to move the bit off the flat face. The housing includes a drive member which may be just a manual rotation of the housing for causing rotation of the tube and thus the bit at the forward presentation end.

Title: Improvements to oxidising processes by oxygen transfer within a liquid medium in a reactor under pressure
Inventor: MUGUET MICHEL
IPC: B01J19/00
Filed: 2001-12-18
Abstract: Methods for oxidizing a liquid with an oxidization gas in a closed volume reactor. A feed liquid which contains compounds to be oxidized is fed into the closed volume reactor, and a feed gas containing oxygen is fed into the reactor so as to form a gas overhead above the feed liquid. The overhead is later purged at a specific rate so as to ensure a predetermined oxygen partial pressure is maintained in the gas overhead. The value of this partial pressure corresponds to a predetermined, desired rate of oxidation of the compounds contained in the feed liquid.

Title: High vertical resolution antennas for nmr logging
Inventor: TAHERIAN REZA
IPC: G01R33/44
Filed: 2003-08-20
Abstract: A high vertical resolution antenna design is provided for use in an NMR measurement apparatus. Multiple coils are situated along the length of a magnet. A primary coil is energized to cause an oscillating magnetic field in a portion of earth formation surrounding a borehole. A secondary coil having smaller dimensions than the primary coil is operated to receive spin echoes from a depth of investigation associated with the secondary coil. A distance sufficient to minimize electrical coupling separates the coils. The separation distance can be reduced by selecting a secondary coil with orthogonal polarization to the primary coil.  Alternatively, a cross coil configuration can be implemented where the orthogonal secondary coil at least partially overlaps the primary coil, thereby reducing the overall length necessary for the polarizing magnet.

Title: Microneedles for minimally invasive drug delivery
Inventor: CHO STEVE T
IPC: B81C1/00
Filed: 2002-05-22
Abstract: The present invention provides a microneedle incorporating a base that is broad relative to a height of the microneedle, to minimize breakage. The microneedle further includes a fluid channel and a beveled noncoring tip. Preferably arrays of such microneedles are fabricated utilizing conventional semiconductor derived microscale fabrication techniques. A dot pattern mask is formed on an upper surface of a silicon substrate, with each orifice of the dot pattern mask corresponding to a desired location of a microneedle. Orifices are formed that pass completely through the substrate by etching. A nitride pattern mask is formed to mask all areas in which a nitride layer is not desired. A nitride layer is then deposited on the bottom of the silicon substrate, on the walls of the orifice, and on the top of the silicon substrate around the periphery of the orifice. The nitride layer around the periphery of the orifice is offset somewhat, such that one side of the orifi ce has a larger nitride layer. Anisotropic etching is used to remove a substantial portion of the substrate, creating a plurality of angular, blunt , and generally pyramidal-shaped microneedles. A subsequent removal of the nitride layer, followed by an isotropic etching step, softens and rounds out the blunt angular microneedles, providing generally conical-shaped microneedles. The uneven nitride layer adjacent the orifice ensures that the microneedles will include a beveled tip. Such microneedle arrays are preferably incorporated into handheld diagnostic and drug delivery systems.< /SDOAB>
