Patent CA-2081214-A1 (CA)
Inventor: BABCOCK H NASH
IPC: E01C7/12
Filed: 1992-02-27
Abstract: éthode d'immobilisation des déchets dangereux. Comprend, d'une part, la préparation d'une composition cimentaire sèche capable de durcir, formée de fines particules d'au moins un liant de ciment, et, d'autre part, l'utilisation d'une certaine quantité de cette composition dans les déchets dangereux avec ou sans l'ajout d'un volume d'eau, et sans avoir à intervenir en aucune façon pour mélanger la composition cimentaire et l'eau, le mélange se faisant par simple contact. La plus grande partie des particules de la composition cimentaire ont à peu près la même vitesse de chute dans l'eau. L'eau entre en contact avec la composition cimentaire sèche lorsque celle-ci est versée dans le volume d'eau et vient ainsi hydrater les particules de la composition cimentaire sèche qui s'enfoncent dans l'eau en chassant l'excès d'eau pour former une masse essentiellement homogène. On laisse ensuite la composition cimentaire hydratée figer et durcir en une masse solide. Le temps nécessaire à l'immobilisation complète des déchets dangereux peut varier d'à peine quelques secondes à plusieurs heures et même plusieurs jours. La composition cimentaire peut comporter un agent de neutralisation des déchets dangereux.

Title: Compliant drive link for tenter
Inventor: DUNCAN JEFFREY B
IPC: D06C3/10
Filed: 1992-12-18
Abstract: Abstract of the Disclosure A tentering machine having a compliant drive link allows for a considerable rate of stretch in a tentered fabric, web  or  film without  the  distortion  or bowing  frequently observed with the tentering machines of the prior art.  The tentering machine includes two conveyor tracks adjacent to and facing one another, each conveyor track having a number of fabric edge holders slidingly directable thereabout.  A fabric, web or film, grasped on opposite edges by the fabric edge holders, is conveyed thereby through the tentering machine in the  space  between  the  two  conveyor  tracks.    Widthwise stretching occurs where the conveyor tracks of the tentering machine have sections on each side of the fabric which diverge from one another, while the two conveyor tracks may be parallel to each other on the two sides of the fabric in applications where prevention of shrinkage is of interest.  The fabric edge holders on each conveyor track are run at a substantially common speed by drive chains.  Elongated, spring-like compliant drive links extend from the drive chains to the fabric edge holders, but are not connected thereto.  The compliant drive links allow adjacent fabric edge holders to move relative to one another, permitting a considerable rate of stretch without the distortion or bowing of the fabric, web or film observed during the use of prior-art tentering machines.

Title: Intermittent, machine-direction fluff contouring roll
Inventor: KUGLER JOSEPH M
IPC: D04H1/70
Filed: 1993-02-23
Abstract: ABSTRACT            A distinctive apparatus for contouring a fibrous web comprises a supplying mechanism for providing a fibrous web which defines an interconnected series of appointed article segments along a length dimension of the web.  A conveying mechanism moves the web at a selected speed along an appointed machine direction.  A scarfing mechanism removes predetermined quantities of fibers from selected regions of the fibrous web.  The scarfing mechanism is constructed to provide each of the article segments with a selected contoured basis weight which varies at least along the length dimension of the segment in a selected correspondence with a predetermined scarfing pattern.  The scarfing pattern is provided by an outer peripheral surface of the scarfing mechanism, and the pattern is configured to have a selected variation at least along a movement direction of the scarfing mechanism.  A regulating mechanism controls a relative movement between the conveying mechanism and the scarfing mechanism to provide the selected correspondence and to thereby form the selected contoured basis weight on substantially each of the article segments.

Abstract: Intracavity Raman lasers comprising a pump resonator and a Raman resonator that eliminates alignment problems associated with multi-mirror intracavity lasers. The pump resonators include a laser rod and a pump source.  In one embodiment, a first retroreflector is disposed at one end of the pump resonator, and an output mirror is disposed at an opposite end thereof.  A Q-switch, a dichroic mirror, and a prism are disposed between the laser rod and the output mirror.  The pump resonator radiates pump energy at a first wavelength (1.06 µm) between the first retroreflector and the output mirror.  The Raman resonator includes a Raman gas cell having first and second lenses disposed on opposite ends thereof for focusing laser energy into the Raman cell, and a second retroreflector that forms one end of the Raman resonator. The output mirror forms an opposite end of the cell, and the dichroic mirror and the prism are disposed between the second retroreflector and the first lens.  The Raman resonator radiates Raman laser energy at a second wavelength (1.54 µm) between the second retroreflector and the output mirror.  A second embodiment eliminates the the second retroreflector and dichroic mirror and moves the position of the Q-switch to a point between the retroreflector and the laser rod.  The present lasers are extremely insensi-tive to misalignment and have eyesafe output energy and acceptable beam divergence. The present lasers, in a production design, may be mechanically toleranced so that no optical alignment is necessary.  Due to their self-aligning nature, the present lasers have fewer components and operate at higher pulse repetition frequencies than conventional multi-mirror intracavity lasers.

Abstract: A method for improving the seakeeping characteristics of an icebreaking ship (20) so that the breadth of the ship's hull (21) will be decreased on the aft wide foreship (65) in the vicinity of the water line (22). It can be implemented with solid hull form or so that on the side of the hull there is a section (30) removable with respect to the solid hull, location or position of which will be changed with respect to the hull. In the solid structure on side of the hull there will be formed a recess (60) and above it a reamer (70), rising towards the stern and formed by a sloping surface (71). The recess forms a pass between the bilge keel (24) and the reamer becoming wider towards the stern and joining the hull's narrower part of the aft body (64) of the ship.

Abstract: A key is provided, the body of the key having a movable element incorporated therein, such as a pin, movable between a first indicating position indicating that the door has been locked, and a second indicating position indicating that the door has been unlocked.  Preferably, the movable element comes into contact with another element on the lock itself when the key is rotated, such contact acting to move the pin to the appropriate indicating position.  In the preferred embodiment of the invention, the face of the lock is provided with at least one appropriately-positioned stationary pin which protrudes slightly therefrom, and the body of the key is provided with a movable pin parallel to the face of the lock.  Rotation of the key brings the movable pin into contact with the stationary pin, or at least with one of the stationary pins.  The contact drives the movable pin into the appropriate position to designate locked or unlocked as the case may be.  The homeowner can then tell by looking at the key whether it was last used to lock the door, or to unlock the door.
