Patent CA-2510599-A1 (CA)
Inventor: SHANNON THOMAS G
IPC: D21H17/53
Filed: 2003-11-13
Abstract: The disclosed invention is directed to pulp fibers suitable for forming a wet-laid paper product which include amino-functionality which is non-extractable in an aqueous phase. The pulp fibers may be prepared by applying (35a, 35b, 35c) an amino-functional additive to a fibrous web (33, 36) prior to the finishing operation at a pulp mill. The fibrous web (33, 36) may then be repulped at a papermaking machine (38) to form a paper web (64) which includes the amino-functionalized fibers of the present invention. A paper web formed of the amino-functionalized fibers may display unique and/or improved reactivity toward certain papermaking additives. For instance, the paper webs of the disclosed invention may show dry tensile strength increases of greater than 40 % when treated with a permanent wet strength agent such as a polyamine epichlorohydrin wet strength agent, whereas a paper web which does not include the amino-functionalized fibers of the present invention may show less than a 20 % increase in strength properties when treated with the same strength agents.

Title: Building construction assembly of structural modules
Inventor: ROTH JONATHAN
IPC: E04C2/34
Filed: 2003-02-26
Abstract: A building construction assembly composed of factory-manufactured thermoplastic structural modules which when interconnected at a building sit e then create the entire shell of an edifice having side walls and a roof. Eac h module which is formed of a pair of parallel panels bridged by transverse we bs is provided on either side along its length with a pair of flexible catch flanges projecting from the panels. When assembling these modules to create the shell of the edifice, adjacent modules are interconnected in coplanar relation by a double-faced joiner on each face of which is a pair of teeth. When one face of the joiner is pressed against a side of a module, its catch flanges then flex to snap into and behind the teeth to connect the joiner to this module. The other face of the joiner is similarly connected to the side of an adjacent module whereby the modules are then interconnected in coplana r relation. When it becomes necessary to interconnect four modules in a cross formation, use is then made of a square, quad-faced joiner on each face of which are a pair of teeth which are engageable by the catch flanges projecti ng from the side of the module to be joined to this face.

Title: Metallic pilfer-proof cap
Inventor: MATUKAWA YOSIHIKO
IPC: B65D41/34
Filed: 2003-02-28
Abstract: A metallic pilfer-proof cap, in which the skirt of a skirt portion of a cap can be so separated by a weakening portion having horizontal slits and bridges formed alternately in the circumferential direction of the cap that the skirt may be left in a ring shape as a pilfer-proof band on the side of a container mouth. The horizontal slits formed by shearing in the transverse direction from the outside to leave the bridges are offset radially more inward of the cap at the portion above a shearing plane than at the portion below the shearing plane so that the bridges are formed on the upper side of the shearing plane of the horizontal slits. The upper end portion, as located on the lower side of the shearing plane, of the pilfer-proof band is made to have an internal diameter larger than the maximum external diameter of the annular bulging portion which is formed at the container mouth for retaining the pilfer-proof band.

Inventor: BADENES CORELLA AGUSTIN
IPC: H04L27/34
Filed: 2004-05-11
Abstract: The invention relates to a normalised coherent amplitude and differential phase modulation method for multi-user communications.The invention is characterised in that the information to be modulated in terms of phase difference, which belongs to a set of possible information according to the number of phases of the constellation to be used, contains a one-to-one mapping between the aforementioned set and the set of possible information to be modulated corresponding to the constellation with the maximum number of phases. In this way, bits can be changed by a carrier without sending a new phase reference, the number of information symbols in the frame can be maximised and a low-complexity modulator and demodulator can be used. The invention is suitable for use in multi-user digital communications which require the bits to be changed by the constellation carrier in one data frame, in order to be adapted to the maximum transmission capacity of the channel, to monitor the amplitude variations in same and to enable the transmission of information from one to various users.
