Patent CA-2115729-A1 (CA)
Inventor: KASAHARA YOSHIYUKI
IPC: B24B3/36
Filed: 1994-02-15
Abstract: An apparatus for grinding an elongated knife blade used in a veneer lathe or a veneer slicer has a blade mount with a mounting surface on which the blade is fixed. In order to prevent a thermal distortion of the cutting edge of the blade after it has been ground by the grinding wheel and naturally cools, the blade mount and the blade thereon are cooled by supplying a cooling medium even to an intervening surface or area therebetween. The blade and mount are also cooled entirely by direct contact with the cooling medium. The grinding wheel is controlled such that when it is lowered to abut against the blade, a resistance torque increase is detected and the grinding wheel is raised slightly to a grinding start level from where the grinding feed and stroke of the wheel is started so that interference between the wheel and the blade is prevented during the initial longitudinal stroke of the wheel along the blade.

Title: Postmortem finalization
Inventor: JACKSON FRANKLIN R
IPC: G06F12/00
Filed: 1992-11-19
Abstract: Frequently some final action or sequence of actions needs to be taken when a memory object becomes a garbage object, beyond simply reclaiming the memory occupied by such objects. An automated finalization mechanism performs such a pre-specified set of actions when it has determined that a memory object has become garbage. A  postmortem finalization mechanism performs these finalization actions only after the garbage object has actually been reclaimed by the system's garbage collector. Delaying the execution of the finalization actions until the object in question has been fully reclaimed prevents this object from accidentally being resurrected as a possible side effect of the finalization actions. A  mechanism for supporting postmortem finalization is constructed by extending the capabilities of an automatic storage-reclamation system.
Patent CA-2126153-A1 (CA)
Inventor: RUVANG JOHN A
IPC: E02F3/96
Filed: 1994-06-17
Abstract: An  upper  end portion  of  an  excavation  ripper  shank  is captively and removably retained in a ripper box using a specially designed flex pin connector longitudinally driven into generally aligned openings in the ripper box and shank.   The flex pin connector includes first and second rigid pin members held in a spaced  apart,  parallel,  laterally  facing  relationship  by  a plurality of elastomeric members bonded to facing side surfaces of the pin members.  When the flex pin connector is driven into the aligned  box  and  shank  openings  the  elastomeric  members  are compressed, causing the first and second pin members to drive the shank  and  box  into  forcible  abutment  with  one  another  to substantially eliminate relative side-to-side play therebetween.    Additionally, as the flex pin connector passes through the first and second openings its first and second pin members are caused to pivot relative to one another about an axis parallel to the compression direction of the elastomeric members.  When the flex pin connector reaches its installed position the first and second pin members return to their original pivotal orientation,  and locking  projections  on  their  end  portions  releasably  block longitudinal removal of the flex pin connector.  A second flex pin connector, substantially identical to the first flex pin connector, is removably received in a third opening formed in the ripper box and has outer side portions that resiliently bear against the received ripper shank portion and an interior side surface portion of the third opening that faces such ripper shank portion.

Title: Silanes for the surface coating of dielectric materials
Inventor: BARNER RICHARD
IPC: C07F7/18
Filed: 1994-10-20
Abstract: The present invention is concerned with novel silanes and their application for the silanization of dielectric materials for anchoring biologically active compounds. The silanes have the general formula I (R1R2R3)Si-Y-X wherein R1, R2 and R3 signify alkyl, alkoxy or halogen, but at least one of these groups is alkoxy or halogen, Y signifies an alkylene chain [-CH2-(CH2)n-CH2-], a fluoroalkylene chain [-CH2-(CF2)n-CH2-], (-CH2-(CF2)n-CF2-] with n = 1-20 or an oligooxyalkylene chain -[(CH2)n'-O-(CH2)n"]m- with n', n" = 2-6 and m = 2-6 and X signifies an epoxide, an anhydride of a dicarboxylic acid with 4-5 C atoms, an isothiocyanate, an aryl carboxylic acid chloride or an aryl sulphonic acid chloride, provided that at least one of R1, R2 and R3 is halogen when X signifies an epoxide.      The new silanes according to the invention offer the following advantages:      The reactive groups X of the silanes are hydrolysis-stable but sufficiently reactive for the immobilization of an organic or biological recognition molecule to take place without further activation of the silane layer.      The silanes are suitable for the direct coating of dielectric materials, in particular of dielectric waveguides which are preferably made of ZrO2, HfO2, Ta2O5, SiO2, Al2O3 or TiO2.      The silanes can be applied to the surface of dielectric materials not only from solution, but also from the gas phase.      The hydrolysis stability of the reactive groups gives rise to better stability during storage of silane layers and permits their direct application in an aqueous medium.

Patent CA-2140236-A1 (CA)
Title: Liner tie-back sleeve
Inventor: KENNEDY BRIAN S
IPC: E21B43/10
Filed: 1995-01-13
Abstract: A scoophead/diverter assembly functions to orient and anchor multiple tubing strings at the Y-juncture in an oil or gas well with multiple lateral wellbores. An important advantage of this arrangement is to provide communication to multiple reservoirs or tap different locations within the same reservoir and enable re-entry to these wellbores for remediation and stimulation. The large bore of the scoophead enables a secondary wellbore's production tubing (liner) to pass through until the top of the liner is in the scoophead. In accordance with an important feature of this invention, a novel liner tie-back sleeve is used to thread onto the top of a lateral liner, and locate, latch and provide a seal receptacle to isolate the secondary wellbore's production fluids. The liner tie-back sleeve also includes a running profile for a suitable running tool. The liner tie-back sleeve comprises two cylindrical parts that, when assembled, provide a running tool profile for running the liner in the wellbore. The sleeve has a locating shoulder on the outer surface to indicate when the sleeve is located in the scoophead, and a locking groove for locking dogs from the scoophead to snap into to provide resistance when pulling tension against the sleeve.  Once the sleeve is in place and the running tool removed, an internal latch thread and seal bore is exposed for a parallel seal assembly (or other tool or production tubing) to plug into for isolating the secondary lateral wellbore. Providing the seal point between the parallel seal assembly and sleeve eliminates the need to effect a seal in the scoophead on the large bore side.
