Title: Cylinder lock- key- combination
Inventor: MIELONEN PEKKA
IPC: E05B29/04
Filed: 1999-08-31
Abstract: A cylinder lock and key combination comprises a lock body, a turnable lock cylinder located inside the lock body, and a set of locking discs located inside the lock cylinder.      Each locking disc has a peripheral notch and a key opening and is turnable in the lock body in a first direction by application of turning force to a counter surface bounding the key opening. Each locking disc has an opening position in which its peripheral notch is at the position of an axial slot in the lock cylinder, such that when all the locking discs are in their respective opening positions the peripheral notches form a uniform channel at the position of the axial slot. A locking bar has a locking position in which it prevents turning of the cylinder relative to the lock body and a releasing position in which it is received in the channel formed by the peripheral notches of the locking discs and releases the cylinder for turning relative to the lock body. A key for the lock is insertable in the lock when the locking discs are at an initial position. The key has a set of combination surfaces corresponding respectively to the locking discs, for engaging a counter surface of each locking disc and applying turning force thereto when the key is inserted in the lock and is turned in the first direction, so that the locking discs are turned in the first direction to their respective opening positions. The key opening of at least one locking disc is bounded by at least two discrete counter surfaces, and the combination surface corresponding to that locking disc can be provided selectively with one of at least two combination values, whereby the combination surface engages a selected one of the discrete counter surfaces for applying turning force to the locking disc.

The means (4) also includes a metal ring or union (8) with a groove (9) for receiving the end profile (6) and clamping device in the form of two tension bushes (9 and 10) which can be expanded radially to effect clamping.
Patent CA-2281653-A1 (CA)
Inventor: HESSELBOM HJALMAR
IPC: G02B6/44
Filed: 1998-02-18
Abstract: An optical fiber flexfoil (1) comprises optical fibers adhesively bonded between two flexible foils (3, 7) laminated to each other. A  surface of a base flexible plastic sheet (3) is coated with a pressure sensitive adhesive (5) and optical fibers are bonded to the sheet by the adhesive (5). A top foil (7) having a similar coating (9) is placed on top of the base foil (3) contacting the optical fibers, air located between the foils is removed and the foils are pressed against each other using a rubber bag formed of two superposed rubber sheets (11, 13) to bond the foils to each other only by means of the adhesive coatings (5, 9). The adhesive is selected to have a low glass transition temperature such as below -50 °C and to exhibit visco-elastic characteristics in the temperature range within which the flexfoil is to be used. The lamination of the foils is made at temperatures at the upper limit of the operational range using only moderate pressures. This gives low mechanical stresses on the fibers in the pressing operation. The fibers are not entirely rigidly fixed to the foils allowing them to move a little when bending the flexfoil, so that rather sharp bends of the flexfoil (1) can be made. Also, microbends formed in the lamination process can relax and thus be eliminated what produces a low attenuation in the optical fibers.

Title: Process for epoxidation of propylene
Inventor: CHANG TE
IPC: B01J38/64
Filed: 1998-06-29
Abstract: Propylene is converted to propylene oxide in a highly efficient liquid phase process wherein temperature and pressure are both increased over the course of the epoxidation, which is preferably conducted in a continuous mode of operation. The catalyst used is a heterogeneous catalyst such as titanium silicalite or titania-on-silica. The oxidizing agent is an active oxygen species such as hydrogen peroxide or an organic hydroperoxide. When the desired yield of propylene oxide can no longer be maintained, the catalyst is replaced or regenerated. Regeneration by washing the catalyst with a hot solvent containing a source of ammonium or alkali metal cations is highly effective, especially where the catalyst is a titanium-containing zeolite.

Title: Charged particle beam illumination of blanking aperture array
Inventor: MANKOS MARIAN
IPC: H01L21/027
Filed: 1999-04-28
Abstract: A charged particle beam column (100) efficiently illuminates a blanking aperture array (108) by splitting a charged particle beam (110) into multiple charged particle beams and focusing each charge particle beam on a separate aperture of the blanking aperture array (108). Where an electron source with a small effective source size is used, for example an electron field emission source or Schottky source, crossovers of the individual beams may occur within the separate apertures of the blanking aperture array. Consequently, no demagnification of the beams passing through the blanking aperture array is necessary to form a small exposure pixel on the writing plane. A beam splitter, shown as biprism (104) is aligned perpendicularly to optical axis (A) and splits electron beam (110) into separate beamlets.

Abstract: PRÉCIS  Même avant l'arrivé des systèmes de tubulure dans le domaine de l'acéricultu re le chalumeau était et est toujours communément utilisé afin de récolter la sève  de l'érable. Dans la présente invention, nous avons créé un chalumeau muni d'un e bande d'étanchéité sur la paroi extérieur. Ce chalumeau a bien sûre pour fonction primaire de récolter la sève de l'érable et de l'acheminer au système de tubulure, mais aussi de sceller l'embouchure de l'entaille et aussi le pouvoir d'administrer à l'érable un bactéricide (fongicide, bactéricide, désinfectant, anti-septique ) afin de désinfecter l'entaille où il se trouve. Ceci a pour effet de retarder les préliminaires du processus de cicatrisation de celle-ci à la fin de la saison acéricole.</SDO AB>

IPC: B32B5/00
Filed: 1998-07-23
Abstract: Large composite structures are produced using a vacuum assisted resin transfer molding process. The structures incorporate cores (12), which may be hollow cells or foam blocks. A plurality of cores (12), each of which may be wrapped with a fiber material (20, 22, 24), is arranged in a layer on a mold (29) with a fiber material (20, 22, 24) arranged to form face skins. The assembly is sealed under a vacuum bag (30) to a mold (29) surface. One or more main feeder conduits (14) are provided in communication with a resin distribution network of smaller channels which facilitates flow of uncured resin into and through the fiber material (20, 22, 24). The resin distribution network may comprise a network of grooves (14) formed in the surfaces or the cores (12) and/or rounded corners of the cores (12). The network of smaller channels may also be provided between the vacuum bag (30) and the fiber material (20, 22, 24), either integrally in the vacuum bag (30) or via a separate distribution medium. Resin, introduced under vacuum, travels relatively quickly through the main feeder channel(s) (14) and the network of smaller channels. After penetrating the fiber material (20, 22, 24) to reach the surface of the cores (12), the resin again travels relatively quickly along the cores (12) via the grooves (14) in the cores (12) or the spaces provided by the rounded corners to penetrate the fiber material (20, 22, 24) between the cores (12), if present, and between the cores (12) and the mold (29).
