Patent CA-2199626-A1 (CA)
Inventor: DE AMBROGIO ATTILIO
IPC: B65H9/10
Filed: 1996-06-28
Abstract: The document aligning and feeding device comprises couples of rollers formed by a delivery roller (15) and a backup counter-roller (14), wherein each couple of rollers is subjected to a lower load during the aligning step and a higher load during the successive feeding step. The backup counter-roller is formed by two separate, coaxially coupling counter-rollers, one of which (33) has a lower coefficient of friction with the document and is the one operating during the aligning step, whereas the other (31) has a higher coefficient of friction and is operational during the successive feeding step. This allows the document to rotate freely about one of its corners during the aligning step, and to advance without being deflected during the successive feeding step.

Title: Pretreatment process in flour milling method
Inventor: KANEMOTO SHIGEHARU
IPC: B02B3/00
Filed: 1997-04-29
Abstract: A pretreatment process in a flour milling method in which raw wheat grains are first polished and the polished grains are ground and milled for producing end flour, includes a first polishing step, a second polishing step, a third polishing step, and a step of adding water. In the first polishing step a pericarp of each wheat grain is removed, in the second polishing step a seed coat of each raw wheat grain is removed, in the third polishing step a part of cell walls of aleuron layer cells that was in contact with the removed seed coat is removed so that a cell membrane of the aleuron layer cell is caused to be ruptured and that a substance in the aleuron layer cell is caused to be in a state which permits the substance to flow out. In step of adding water, by adding the water to each raw wheat grain, the substance in the aleuron layer cells is caused to flow out from the aleuron layer cells, resulting in producing a polished grain in a state in which the substance in the aleuron layer cell has been separated from each raw wheat grain. It is possible to increase the yield of the end flour collected by the subsequent grinding operation.

Abstract: Method and apparatus for generating orthogonally encoded communication signals for communication system subscribers using multiple orthogonal functions for each orthogonal communication channel. Digital data symbols for signal recipients are M-ary modulated using at least two n-length orthogonal modulation symbols, which are generally Walsh functions normally used within the communication system. These symbols are provided by a modulation symbol selector (124) typically from one or more code generators (126, 128), and the modulation is such that M equals a product of a total number of orthogonal functions and the number used to generate individual modulation symbols. Each group of log M encoded data symbols from data processing elements (100, 102) are mapped into one modulation symbol using the modulation symbol selection element (124) according to their binary values. In some embodiments, a fast Hadamard transformer is used for symbol mapping. The resulting communication signals are demodulated by correlating them with the preselected number of orthogonal functions, in parallel, and demodulating the results into M energy values representing each orthogonal modulation symbol. The energy values are mapped into energy metric data using a dual maximum metric generation process. The correlation and demodulation can be accomplished using at least two sets of N correlators (142), N being the number of functions used, and applying correlated signals to one demodulator for each set of correlators (144). Each demodulator outputs M energy values representing each of the M mutually orthogonal modulation symbols, which are then combined into a single set of M energy values. In further configurations, coherent demodulators (172, 174) can be used to produce amplitude values for received signals which are then combined (178) with dual maximum metric results (170) to produce composite metric values for data symbols (178).

Abstract: A user sets n=0, his mail account A and password S, then computes V0=E(A,S), W0=E(A,V0), V1=E(A,A~1), W1=E(A,V1) and M0=E(W1,V0), and initially registers W0, W1, M0 and A by e-mail in a mail server. At a visiting site the user sends a service request and A to the mail server from an arbitrary terminal connected to the Internet, and the mail server reads out the authentication session number n corresponding to the identifier A and sends it back to the user. The user computes V n-1=E (A,S+~(n-1)), V n+1=E(A,S~(n+1)), W n+1=E(A,V n+1)-V n=E(A,S~n) and M n=E(W n+1,V n) and sends V n-1, W n+1 and M n to the mail server. The mail server computes E(A,V n-1) and E(W n,V n-1) and if they agree with preregistered W n-1 and M n-1, respectively, the mail server accepts the user as valid and sends a mail message of the user.
