Patent CA-2160194-A1 (CA)
Inventor: MONTGOMERY JAMES R
IPC: B65B69/00
Filed: 1995-10-10
Abstract: A plurality of parallel chain loops have outwardly extending blades and travel in plastic channels over an inclined deck. The chains extend between shafts which rotate in opposite directions and are mounted to the shafts so that alternating chains move up the incline and the others move down. Refuse bags deposited on the deck are torn open by the blades. Small refuse objects fall between the chains and slide down the deck to be discharged, while larger objects are carried by the upwardlymoving chains to the top of the deck. Refuse objects are thereby initially segregated by size.

Patent CA-2162926-A1 (CA)
Inventor: TOWNSEND BRYAN ROBERT
IPC: H04B1/707
Filed: 1994-11-22
Abstract: Un récepteur destiné à des signaux codés de bruit pseudo-aléatoire comporte un circuit d'échantillonnage, de multiples circuits de synchronisation de porteuse et de code, et de multiples corrélateurs numériques. Le circuit d'échantillonnage fournit à chacun des circuits des canaux du récepteur des échantillons numériques d'un signal composite reçu. Les circuits de synchronisation sont de préférence non cohérents du fait qu'ils suivent tout déphasage du signal reçu et ajustent en conséquence la fréquence et la phase d'un signal de référence multiplex généré localement, même en présence d'une distorsion Doppler ou ionosphérique. Les corrélateurs multiples de chaque canal mettent en corrélation les échantillons numériques avec des codes de bruit pseudo-aléatoire généré localement, présentant de multiples décalages, pour produire une pluralité de signaux de corrélation. Ces derniers sont appliqués à un calculateur de paramètres permettant de calculer les paramètres de temps de propagation et de phase du signal à trajet direct, ainsi que de tous signaux à trajets multiples, et de corriger une mesure de distance.

Title: Method and apparatus for reproducing encoded data
Inventor: KAWAMURA MAKOTO
IPC: H04N19/50
Filed: 1996-01-30
Abstract: A method and apparatus for reproducing data compressed in accordance with a motion picture experts group (MPEG) standard and recorded on a recording medium. The data represents a plurality of frames which correspond to a plurality of groups of pictures (GOPs), in which each of the GOPs includes different types of pictures including intraframe predictively (I) encoded and interframe predictively (P) encoded pictures. The compressed data is read from the recording medium, and the type of pictures corresponding to the read data is determined. The read image data is decoded and supplied to a display device. When special processing (such as, random accessing) is performed, image data may not be properly decoded during an initial period. During this time period, an auxiliary signal may be supplied to the display device. Such supply of the auxilliary signal continues until image data corresponding to an intraframe predictively encoded (I) picture and either another intraframe predictively encoded (I) picture or an interframe predictively encoded (P) picture are detected, whereupon the respective image data is properly decoded by utilizing the image data corresponding to the detected P and/or I pictures and supplied to the display device instead of the auxiliary signal.

Patent CA-2183121-A1 (CA)
Inventor: MURAKAMI KAZUO
IPC: B29C35/08
Filed: 1996-08-12
Abstract: The present invention relates to a method for bonding together two disc substrates, at least one disc substrate having a UV transmissive-visible light reflective information recording layer provided on a UV transmissive base. In this method, the disc substrates are bonded together, so that the information recording layer of one disc substrate faces the other disc substrate, by employing UV irradiation to cure a UV curable composition used as a bonding agent.  In the case of the present invention, to cure the bonding agent, UV is irradiated in a single or repeating flash so as not to impair the information recording layer.  As a result, the bonding agent can be cured in a shorter period of time with less energy consumed as compared to the conventional method of using continuous irradiation of UV light to cure a UV curable composition used as a bonding agent.  Accordingly, the present method enables a product disc to be obtained in a shorter time, with less energy used, so that productivity (i.e., number of bondings per unit time) is improved.

Patent CA-2191848-A1 (CA)
Inventor: GILBOA PAZ
IPC: H04J3/06
Filed: 1995-06-02
Abstract: Jitter is limited in the mapping of a first telecommunications signal into a second telecommunications signal moving in a first direction, generating a compensative payload pointer movement of the first telecommunications signal in a second direction which is opposite the first direction. The invention has a particular application to the mapping of three E3 (490a-1 to 490a-3) telecommunications signals which are in the format of a TUG-3 signal into an STS-3C SONET telecommunications signal in the STM-1 VC-4 format. When the STS-3C signal requires a pointer movement due to frequency compensation in the system, a compensative pointer movement at the TUG-3 level avoids eight units of fitter in the TUG-3 signal which could adversely affect system performance.
