Patent CA-2208158-A1 (CA)
Title: Machining vehicle
Inventor: ISHIMOTO KATSUZOU
IPC: B23K9/127
Filed: 1997-06-19
Abstract: A machining vehicle includes a vehicle body, drive mechanism, wheels rotatably supported by the vehicle body, rotation transmission mechanism for transmitting to the wheels rotation generated by the drive mechanism, and a permanent magnet disposed on the vehicle body. The permanent magnet assumes an operation position and a retracted position.      The machining vehicle further includes a lever connected to the permanent magnet, a machining torch attached to the vehicle body, and a handle fixed to the vehicle body. When an operator places the machining vehicle on the travel surface and rotates the lever slightly, an attraction force is generated between the permanent magnet and the travel surface, so that the permanent magnet swings down quickly and assumes the operation position. While the permanent magnet is in the operation position, a sufficient frictional force can be generated between each wheel and the travel surface. When the operator operates the lever such that the permanent magnet moves to the retracted position, the attraction force generated between the permanent magnet and the travel surface decreases to zero.

A doctor blade is mounted in engagement with the queen roll in line with the tail to direct the tail away from the queen roll and towards the next section of the papermaking machine. Guide trays positioned downstream of the doctor blade guide the tail to the next section of the papermaking machine. The doctor blade can be mounted stationary against the queen roll.
Patent CA-2209806-A1 (CA)
Inventor: MASLOW BRENT
IPC: E04H15/04
Filed: 1997-07-07
Abstract: A tent arranged to be supported above the ground is described. The tent comprises an all-weather suspended shelter that incorporates a collapsible, flexible frame which supports a bedding area. The frame comprises T-shaped members, pipes and arcuate rods. The T-shaped members and the pipes are stitched into the base of the tent such that the pipes reversibly engage the ends of the T-shaped members, thereby connecting adjacent T-shaped members along the length of the base of the tent. The arcuate rods are inserted into the base of the T-shaped members on opposite sides of the base so that the arcuate rods extend across the width of the base of the tent. Thus, the bedding area retains its shape and distributes the weight of a person in the bedding area as a result of the design of the frame. Specifically, the frame is designed to maintain the characteristic shape of the bedding area while remaining flexible and taut. As a result of this arrangement, the weight of the person in the bedding area is transferred to the support structures from which the tent is suspended.

IPC: B01D53/56
Filed: 1998-04-02
Abstract: The present invention provides a method of controlling NO x emissions from a glass melting process in which combustion fuel produces exhaust gas in a melting furnace including NO x compounds. Furnace exhaust gas passes from the melting furnace through a regenerator to a zone downstream from the regenerator. Ammonia is injected into the furnace exhaust gas at the downstream zone while the furnace exhaust gas is within a desired temperature range to reduce the amount of NO x compounds. Additional gas is introduced into the furnace exhaust gas as it moves from the regenerator to the downstream zone whenever the furnace exhaust gas has a temperature which is outside the desired temperature range at the downstream zone so as to modify the furnace exhaust gas temperature such that the furnace exhaust gas is within the desired temperature range when furnace exhaust gas reaches to the downstream zone. In one particular embodiment of the invention, the additional gas is the exhaust from an excess air burner which is injected into the furnace exhaust gas at a temperature such that the furnace exhaust gas and the injected gas have a combined temperature between about 870 to 1090°C at the downstream zone.
