Patent CA-2482537-A1 (CA)
Inventor: BI DAOSHEN
IPC: B42D15/10
Filed: 2003-05-09
Abstract: The present invention relates to assembling identification documents in an over-the-counter issuing environment. In one implementation of the present invention, we provide an identification document capable of being printed by an ink jet printer-based system in an over-the-counter environment. The identification document comprises a core layer and a first indicium. The core layer has a first surface, and the first indicium is printed directly onto at the first surface of the core layer. The first indicium is formed by a pigmented ink jet ink. The core material can have an affinity for a particular substance (e.g., water) and the pigmented jet ink can include that substance (e.g., an aqueous-based ink jet ink). An identification document substrate can receive pigmented ink jet ink from an ink jet printer without requiring a receiver layer or receiver coating on the substrate. The absence of the receiver layer allows for direct bonding of additional layers, such as laminates, to an unprinted substrate, thereby not interfering with the bonding mechanism of the laminate to the substrate. Identification documents formed in this manner can meet or exceed all AAMVA, ANSI, and ISO requirements.

Title: Self-sealing retractable writing instrument
Inventor: CARROLL CRAIG
IPC: B43K5/17
Filed: 2003-04-17
Abstract: This invention provides a retractable writing instrument (100) that substantially prevents writing fluid from evaporating through the tip (102) when the tip (102) is in a retracted position to eliminate the need for a cap.  Within the writing instrument (100) is an enclosure member (300) that has a vapor chamber (306). In the retracted position, the tip (102) of the writing instrument (100) is within the vapor chamber (306) to substantially seal the tip (102) from ambient air so that writing fluid does not evaporate through the tip (102) The enclosure member (300) has a lip (302) that opens to allow the tip (102) to move forward and extend from the writing instrumen (100) so that writing fluid can be delivered to the writing surface for writing. When the tip (102) is moved back into the retracted position the lip (302) closes to substantially seal the tip (102) from the ambient air. An external compression may be made of a material that is durable so that the lip (302) does not wear out after many cycles of moving the tip (102) between the retracted and protracted positions, such as silicone, butyl rubber, and thermoplastic vulcanizate (TPV) material including butyl rubber cross-linked with polypropylene.

Title: Method for the production of hybrid spherical molded bodies from soluble polymers
Inventor: SCHULZE THOMAS
IPC: C04B35/486
Filed: 2003-05-14
Abstract: The invention relates to a method for producing hybrid spherical molded bodies from soluble polymers and at least one embedded additive. According to the inventive method, an additive-loaded polymer solution is dispersed in an inert solvent, said dispersion process being carried out at a reduced pressure. The resulting particle dispersion is cooled to a temperature lying below the solidification point of the polymer solution. The stabilized particles of the polymer solution are separated from the inert solvent. The separated particles of the polymer solution are precipitated in a solvent coagulating the polymer.  The solvent-moistened polymer particles are dried until said particles are maximally condensed, and the resulting particles that are made of polymer and the additive are sintered by means of a thermal treatment so as to be turned into porous and/or highly condensed molded bodies. The inventive method makes it possible to obtain highly stable molded bodies which do not sinter together during the sintering process.

Title: Method for joining two metal sheets respectively consisting of an aluminium material and an iron or titanium material by means of a braze welding joint
Inventor: LEITNER ALOIS
IPC: B23K35/24
Filed: 2003-10-06
Abstract: A method is described for joining two sheets (1, 2) of aluminum material on the one hand and iron or titanium material on the other hand by a welding-soldering joint by using a filler, with the iron or titanium material being provided at least in the joining region with a coating preferably on the basis of zinc or aluminum before the filler is applied by forming a weld seam (4) under melting. In order to provide advantageous joining conditions it is proposed that the two sheets (1, 2) are joined in the form of a butt-joint, with the filler on the basis of aluminum being applied for the formation of the weld seam (4) on both sides of the sheet in a region bridging the joint onto the sheet (1) made of iron or titanium material in a width (b) corresponding to at least three times the thickness (d) of said sheet (1).

Assertions (322, 422) from an authentication authority (318, 418) can be used to establish identities of the participants.  Positive and negative events (342, 344) can be determined based on controlling events (340) and if, when, how often requests for a key for decryption occur.  The key server can also store information from assertions in association with a transaction ID, to establish senders and recipients of communications in a manner that cannot plausibly be repudiated and can easily be audited.

Abstract: A process of making staple fibers of poly(trimethylene terephthalate) includes feeding undrawn yarn (1) to a dip tank (2), forwarding by rolls (3, 4) and wetted under water. Wetted undrawn yarn (1) is forwarded by rolls (5, 6, 7, 8, 10) to a first drawing stage in a dip tank (9) and is partially drawn between rolls (10,11) under water in the dip tank (9). The yarn (1~) is then partially drawn by rolls (11, 12, 13, 14, 15, 16) which are driven at a faster speed than roll (10). The partially drawn yarn (1~~) is then rewetted by water spray jets (17) and is further drawn by rolls (18, 19, 20, 21) and puller rolls (22, 23) which are driven at a faster speed than roll (16). Nip rolls (5~, 8~, 14~, 22~, 25~) are used to minimize yarn slippage. After the second drawing, a finish sprayer (24) applies a dilute processing finish to the drawn yarn (1~~~), which is then forwarded and maintened under tension by puller rolls (25, 26) into a suffer box crimper (27) by driven crimper nip rolls (26~), where it is crimped and thermofixed by application of steam (28). The crimped yarn (1~~~~) is then forwarded in a relaxed state throuph a conventional belt dryer (29), cut by a rotary cutter (30) and baled (31) for storage and shipping.
