Title: Optically-guided indicia reader system
Inventor: ALEXANDER CATHERINE
IPC: G06K9/20
Filed: 1998-01-23
Abstract: An optically-guided indicia reader (10) system including a conveyor (12) carrying a parcel (14) bearing a destination address (20). An illumination source (24) defines a area (26) to assist the positioning of the parcel (14) on the conveyor (12). A scanner (32) and a computer memory (42) of a character recognition system (40) are operated so as to store an image of a region defined with respect to the moving illuminated area (26). A sensor assembly (28), including a height sensor and reflectivity sensor, is located toward the downstream location of the illumination source (24). The scanner (32) includes internal components (33) well known to those skilled in the art that automatically focuses the scanner in response to height data, and adjusts the gain of the scanner (32) in response to reflectivity data, so that the scanner (32) generates a clear image of the top of the parcel (14) as the parcel passes beneath the scanner (32). A photo sensor (45) is positioned upstream from the scanner (32) to detect the presence of the parcel (14). The video data generated by the scanner (32) may be stored in the computer memory (42) only when the beam (50) of the photo sensor (45) is broken. A time delay may be imposed to account for the distance between the beam (50) and the scan line (34). Alternatively, a moving-light illumination source (224) defines a spot (230) that moves at the same speed as the conveyor (212) to assist the positioning of the parcel (214) on the conveyor (212).

Patent CA-2280147-A1 (CA)
Inventor: KICKLIGHTER KEVIN C
IPC: H04L69/40
Filed: 1998-02-03
Abstract: A redundancy arrangement for use in connection with a programmable telecommunications switch or other device. An active hardware device, such as an ISDN packet engine card, is paired with a substantially identically configured standby device. During operation, the active device, in addition to performing all of its normal functions, also advises the standby device of all events which have an effect on the operational state of the active device. By ensuring that the standby device processes the same events in the same sequence as the active device, the standby device's operational state continuously tracks that of the active device. Should the active device malfunction or be taken out of service, the standby device becomes active without significant interruption or loss of service.

Patent CA-2282614-A1 (CA)
Inventor: LOGAN MARK C
IPC: F21V19/02
Filed: 1999-09-16
Abstract: A lamp assembly adjustable between narrow beam and wide beam light distributions, the lamp assembly is particularly intended for housing lamping or the like for mounting to industrial emergency unit fixtures of differing size and conformation. At least one and preferably two of the lamp assemblies are mounted to a unit fixture in spaced relation to illuminate critical areas within an industrial or commercial space during emergency conditions, such as failure of mains power, to allow evacuation of the space. In order to illuminate the desired areas, each of the lamp assemblies can be adjusted along an internal track to allow light to be directed toward a particular location within a wide range of possible locations, thereby facilitating illumination of the most desirable area in the vicinity of the unit fixture for a particular mounting location.  Additional flexibility in the delivery of illumination to a desired area is provided by adjustability between narrow and wide beams.

Title: Procede de formage par utilisation de zones de chauffe discretes
Inventor: FREEMAN RICHARD B
IPC: B21D26/033
Filed: 1998-03-27
Abstract: Le dispositif de formage de la présente invention comporte une pluralité de zones de chauffe discrètes (18a-18d) réparties le long de l'axe longitudinal et en périphérie d'une cavité de moulage (23). On a la possibilité de chauffer une zone de façon que la partie de tube chauffée devienne plus élastique que les parties non chauffées du tube. Il en résulte qu'il y a besoin de moins de force axiale et de pression radiale pour provoquer la nécessaire déformation du métal contre les moitiés de moules (12, 14). Les zones de chauffe (18a-18d) sont de préférence alimentées au moyen d'une série de bobines d'induction (16a-16d) réparties le long de l'axe longitudinal et en périphérie du tube (23). Chaque bobine d'induction (16a-16d) peut être activée individuellement de façon à pouvoir chauffer de façon contrôlée les parties sélectionnées du tube (26).

Title: Electrode type soderberg for making silicon alloys and silicon metal
Inventor: DOSTALER JACQUES
IPC: H05B7/107
Filed: 1998-04-27
Abstract: The self-baking electrode suitable for use in an electric arc furnace comprises an elongated open ended electrically conductive casing for extending generally vertically within the furnace. A central core made of a heat conductive material is disposed within and spaced from the casing. A  framework within is securing the central core to an inner surface of the casing for holding centrally the central core within the casing and for preventing an extrusion of the central core downward. The central core is surrounded by a carbonaceous electrode paste devised to cure into a solid electrode upon heating and to bond to the central core. This self-baking electrode allows the production of silicon metal in a Oderberg-type furnace without any modification to the usual slipping system or addition of another slipping system. An electrode according to the invention allows the same furnace to produce both FeSi of any grade and Si metal without any downtime between the gradual change from one product to the other and each time at the lowest electrode cost.

Title: Method and apparatus for braking an agricultural feed bagger
Inventor: CAMERON DANIEL ALEXANDER
IPC: A01F25/14
Filed: 1999-11-10
Abstract: A method and apparatus for braking an agricultural feed bagger includes the following steps. A first step involves providing an agricultural feed bagger having a frame. The frame includes a tunnel with an intake end for receiving material to be bagged and an output end adapted to receive an open mouth of an agricultural bag. A second step involves positioning a body at a remote end of a linkage which extends outwardly from the frame into a flow stream of agricultural feed entering the open mouth of the agricultural bag. The flow of agricultural feed acting against the body serves to slow the forward progress of the agricultural bagger, as the force exerted against the body is transmitted, via the linkage, to the frame.

Abstract: A system, device, and method for supporting multiple virtual private networks in an MPOA/NHRIP communication network involves encoding a Virtual Private Network (VPN) identifier in certain MPOA/NHRP control messages in order to associate those MPOA/NHRP control messages with a particular VPN, and using an in-band signaling technique to add/remove VPNs to/from a connection. Packets from multiple VPNs are multiplexed over the connection. Each packet is associated with a particular VPN. If packets do not inherently include information from which the VPN can be ascertained, then a VPN  identifier is encoded in the packet. The VPN identifier may be encoded in the packet via a tagging mechanism, in which each VPN is associated with a unique tag, and a tag is included in each packet. The VPN identifier may alternatively be encoded in the packet by including the VPN  identifier in the packet, for example, in a header (such as an LLC/SNAP header) within the packet.

Abstract: An all terrain vehicle, also know. as an ATV, has a seat designed to comfortably accommodate a rider over a wide variety of rugged terrain. The seat is profiled so that the rider may easily shift body weight and lean with the vehicle while traversing steep and uneven terrain. The seat has a dip and taper positioned beneath a riders' knee and lower thigh to provide the profile. The ATV is also provided with front fenders and mud flaps to protect the rider from debris. The fenders rotate with the wheel to provide the rider with maximum wheel visibility and access. The fenders can also be releasable, thereby rotating around the axis of rotation of the front wheels to break free from obstacles and provide easy access to the wheels beneath the fender.      The ATV provides exceptional rider comfort and control.
