Patent CA-2241104-A1 (CA)
Inventor: GILBERT DALE A
IPC: H02G3/00
Filed: 1998-06-18
Abstract: A cutting tool and associated positioning templates locate and cut rectangular junction box holes in dry wall or similar sheet material forming structural surfaces. Templates defining a medial positioning slot and providing a pair of spaced positioning pins are carried by pre-established junction boxes and surface sheeting material is established thereover with the positioning pins projecting through the sheet material to indicate positioning slot location. The tool provides a body articulately carrying two perpendicular pairs of spaced parallel saw blades that are moved reciprocably by spring biased driving linkage to cut rectilinear holes in the sheet material over the junction boxes. The saw blades have convexly arcuate edges defining cutting teeth of opposite pitch on each side of the arcuate edge of the tool to aid positional maintenance and prevent chatter during cutting. A positioning blade carried by the body and extending beyond the saw blades passes through sheet material between the positioning pins and into the positioning orifice of the positioning template for tool positioning. The tool is partially covered by a peripheral casement carried by the body and is powered by an independent powering source positionally maintained by the casement.

Title: Method and system for reducing polymer degradation products in two stage injection molding machines
Inventor: CHOI CHRISTOPHER W M
IPC: B29C45/54
Filed: 1999-03-15
Abstract: A method and system of operating a two stage injection molding machine wherein movement of the injection plunger in the shooting pot is co-ordinated with movement of the plasticizing screw and melt flow into the shooting pot such that the plunger provides minimal resistance to the melt flow into the shooting pot while avoiding the production of voids or air inside the melt. The undesired shear forces to which the melt is exposed are thus reduced, correspondingly reducing the melt degradation products which would otherwise result.

Title: Receipt form handling system for automated banking machine
Inventor: HOOVER TIMOTHY R
IPC: B65H29/58
Filed: 1997-11-25
Abstract: A receipt form handling system for an automated banking machine includes a printer (30) which prints indicia on paper extending in a paper path (151). Paper is moved in the paper path by engagement with a drive mechanism (157, 159). Paper sheets are delivered by the drive mechanism to a delivery area, which includes a nip (114) of a sheet transport (26). The transport removes the sheets from the delivery area. A cutter (153) is positioned in the paper path and operates to selectively cut the paper. A sensor (155) is positioned at a location in the paper path upstream from the cutter.      A controller (112) is in operative connection with the sensor and the cutter. The controller operates the cutter so that the paper is cut to produce a form sheet after indicia is printed on a portion of the paper. Upon the sensor detecting an approaching end of the paper, the controller ceases operation of the cutter. This avoids producing forms that are of insufficient length to be handled by the drive or transport.

Title: Desetalement de signaux de communications a spectre etale a sequence directe

IPC: H04B1/707
Filed: 1997-11-12
Abstract: Cette invention présente un certain nombre d'architectures de complexité réduite destinées à désétaler des signaux de communications à spectre étalé à séquence directe. Dans une première architecture de désétalement pour une unité de retrait de séquence, les échantillons complexes reçus à éléments espacés sont inversés en fonction de la phase traitée d'une séquence d'étalement complexe. En outre, les valeurs d'échantillons en phase et à quadrature de phase sont commutées entre elles en fonction de la phase traitée. Dans une deuxième architecture de désétalement, dans une unité de retrait de séquence, les échantillons complexes reçus à éléments espacés sont traités dans le domaine logarithmique, où la phase de la séquence d'étalement complexe est ajoutée à la phase détectée, et le signal complexe qui en résulte est ensuite reconverti en coordonnées cartésiennes. Dans une troisième architecture de désétalement pour un corrélateur, les opérations de retrait de séquence et de corrélation sont effectuées dans le domaine logarithmique où on calcule la moyenne arithmétique des amplitudes et des phases du signal complexe résultant et on les reconvertit en coordonnées cartésiennes. Dans une quatrième architecture de désétalement, également pour un corrélateur, les opérations de retrait de séquence et de corrélation sont effectuées dans le domaine logarithmique à l'aide d'un calcul de moyenne circulaire. Dans une cinquième architecture de désétalement, également pour un corrélateur, où des séquences constituantes multiples sont combinées les unes aux autres pour former une séquence globale et où l'une de ces multiples séquences constituantes est partagée par tous les canaux, un retrait de séquence commun est prévu pour retirer la séquence partagée de tous les canaux. Les signaux qui en résultent sont ensuite envoyés à plusieurs corrélateurs individuels pour effectuer le retrait de séquences spécifiques de canaux.
