Inventor: SCHULTE PETER
IPC: E06B9/17
Filed: 1996-02-08
Abstract: A curtain bottom tensioning assembly comprised primarily of a resilient member (50) extending across the bottom of the door (10). The resilient member (50) is directly or indirectly coupled to a guide extension (100) extending beyond the leading edge of the door (10) and engaging vertical guide members (20, 30) to guide the door (10) in a vertical plane. The guide extensions (100) also engage the vertical guide members (20, 30) to restrict the guide extensions (100) from moving horizontally toward the curtain (10). The coupling between these horizontally restricted guide extensions (100) and the resilient member (50) places a tension on the resilient member (50). The resilient member (50) is thus stretchedacross the bottom of the door or curtain (10), and serves as a bottom bar that also substantially conforms to or deflects around an obstruction, thus preventing or minimizing damage to the door (10), the bottom bar and the obstruction.

Patent CA-2230009-A1 (CA)
Title: Anti-tamper integrated circuit
Inventor: CANDELORE BRANT
IPC: G06F21/00
Filed: 1998-02-20
Abstract: An anti-tamper integrated circuit (IC) apparatus is adapted for use with an IC that carries an active component, such as a secure processor, which requires a constant power signal to operate.      If the power signal is interrupted, data is erased from a volatile memory of the secure processor. The memory is located within the IC package. An external power signal is coupled to the memory via a conductive path which is carried outside the housing and which may be embedded in a decoder board, micro-module substrate, or smart card body in which the IC is carried. The conductive path may carry the power signal directly to the memory, or it may carry the power signal to bias a transistor. Removal of the IC package from the decoder board, micro-module substrate or smart card, will open the conductive path and interrupt the power signal to the memory by causing a short circuit or an open circuit. As a result, the data stored in the memory will be lost.      The apparatus therefore deters a pirate from tampering with the IC.

Inventor: NOMURA MANABU
IPC: B29K307/04
Filed: 1998-05-06
Abstract: Disclosed is a method of molding a fiber-reinforced resin laminate which can manufacture a lightweight laminated molding having excellent mechanical characteristics regardless of the shape of a molding, which can readily unite a surface coat material and a molding while the surface coat material is held in good condition, and which can impart excellent appearance to a laminated molding. Also disclosed is a laminated molding manufactured by the method. The method uses a molding material which contains fiber-containing thermoplastic resin pellets which, in turn, contain reinforcing fibers having a length of 2 mm to 100 mm. The reinforcing fibers account for 5% to 70% by weight of the molding material.      A molten resin obtained through the plasticization of the molding material is injected into a die, onto which a surface coat material for covering the surface of a molding is previously attached. After injection of the molten resin into the die cavity is started, a movable die is advanced so as to compress the molten resin contained in the die cavity, followed by expansion of the volume of the die cavity to that of an intended molding.

Abstract: This invention is a dental implant system having a temporary abutment (110) made of plastic. An impression coping (226), also made of plastic, is attached to the temporary abutment using a snap fit. This snap fit obviates the need to remove the temporary abutment during the process of taking an impression of the mouth in the area around an implant. The cap (218) may be provided for the temporary abutment that is attached thereto using the same snap fit mechanism.  The snap fit mechanism comprises projections (142) formed on one of the components and recesses (238) formed on the other of the components, where the projections engage the recesses to maintain the components in a desired position relative to each other against incidental force. However, these components may be separated by deliberate application of manual force when required.

Abstract: A process is disclosed for treating the scrubbing water from the gas scrubbing process in an iron ore reduction plant. The scrubbing water is brought into direct contact with the gas in two gas scrubbers (1 to 4) arranged in two successive scrubbing stages at the gas-side, is withdrawn from the gas scrubbers and is supplied again to the gas scrubbers after the solids it contains are separated, and after it is treated and cooled. The scrubbing water is separately withdrawn from the two scrubbing stages and only the scrubbing water from the first scrubbing stage is largely freed from solids in a thickener (6), then led into a warm water container (8). The scrubbing water from the second scrubbing stage is directly led into a return water container (10) in which it releases carbon dioxide-rich flash gas led into the scrubbing water in the warm water container to enrich it with carbon dioxide. The scrubbing water from the warm water container is cooled in a heat exchanger (19), then fed back to the gas scrubbers of the two scrubbing stages together with the scrubbing water from the return water container (10). Moreover, part of the carbon dioxide-rich scrubbed gas or part of the carbon dioxide-rich water contained in the return water container may also be led into the warm water container to enrich the scrubbing water in the warm water container with carbon dioxide.
