Patent CA-2134609-A1 (CA)
Title: Folding marker for agricultural implement
Inventor: HAUGEN OLIVER P
IPC: A01B69/02
Filed: 1994-10-28
Abstract: An improved folding marker for an agricultural implement that is partially self-supporting in the use position and during a portion of the folding operation. An inner arm is pivotally attached to the agricultural implement for simultaneous movement in both the horizonal and vertical directions. A caster wheel is attached to the inner arm to support the inner arm above the ground. An outer arm is pivotally attached to the inner arm for movement in a generally vertical direction. A marker device is attached to the outer arm for scoring the ground. An actuator is attached to the implement and the back portion of the inner arm for moving the inner arm between the use position and backwards toward the rear of the implement to a transport position. A series of pulley systems are attached to the marker so that the inner and outer arms raise vertically upward when the inner arm is moved from the use position to the transport position, and vice versa.
Patent CA-2136202-A1 (CA)
Inventor: PETERSON JEFFREY L
IPC: B23K9/067
Filed: 1993-04-30
Abstract: A high frequency, high voltage starting circuit (10) for a plasma arc cutting torch (16) is operated in pulses to restart the torch if an initial arc extinguishes before the arc transfers to the workpiece (24). The starting circuit (1) includes a D.C. power supply (28) with its negative output (28A) connected to an electrode (18) of the torch (16). A positive output (29b) is connected to a nozzle (22), and at a higher positive voltage, to a workpiece (24). A surge injector circuit (38) of a resistor (R2) and surge capaci-tor (C4) is connected in parallel with the power supply to supply current to the arc as soon as breakdown occurs. The duration of the interval between restart pulses is sufficient to allow the surge injector circuit (38) to recharge to a value that will reliably restart the arc as the power supply ramps up to a steady state pilot arc current.
Patent CA-2138126-A1 (CA)
Inventor: DIAMOND GEORGE BERNARD
IPC: B65D83/38
Filed: 1993-05-26
Abstract: A low pressure aerosol dispensing can which is distinguished from existing high pressure aerosol dispensing cans. The generally cylindrical can has a thin wall thickness, like that of a carbonated beverage can, which can be distorted by finger pressure but whose shape is maintained by internal gas pressure. The liquid contents to be dispensed and the propellant gas are mixed in the can. The dispensing valve at the top of the can dispenses the liquid contents and propellant in a controlled manner. The valve may include an additional narrow bore vapor tap between the gaseous propellant head space in the can and the valve chamber for delivering extra gas for atomizing the liquid and propelling it from the nozzle. The gas pressure in the can is coordinated with the can wall and bottom thickness so that the can will have sufficient distortion resistance and burst resistance at elevated temperature. Yet the can has side walls of a thickness low enough to permit the can to be easily crushed by hand pressure when the can is empty.

Patent CA-2140463-A1 (CA)
Title: Circular saw leveling and tensioning machine
Inventor: BROWN ERNEST W
IPC: B23D63/18
Filed: 1995-01-18
Abstract: A circular saw blade straightening and tensioning machine has a set of straightening and tensioning rollers on both sides of a saw blade. The rollers are mounted on parallel shafts. Each shaft has a hub at its end, comprising a center portion horizontally eccentric with respect to the center line of the shaft, and a pair of side portions disposed on opposite sides of the center portion. Each of the side portions is horizontally eccentric with respect to the shaft center line, but in a direction opposite to that of the center portion. A roller is rotatably mounted on each of the center and side portions of the hubs. An actuator rotates each of the upper and lower shafts selectively ninety degrees in both the clockwise and counterclockwise directions. Rotation of the shafts selectively force a center roller against one surface of the saw blade while simultaneously forcing the side rollers against the other surface of the saw blade, thereby to level deformations in the blade. Rotation of the shafts in opposite directions forces the center rollers on both shafts against both surfaces of the saw blade, thereby to tension the blade. A sensor includes a movable foot pivotably mounted intermediate four fixed foot supports. The movable foot carries a gauge that measures the deviation underneath the movable foot from the plane determined by the fixed supports.

Abstract: A method and apparatus for a command system is disclosed. Commands include variables that reflect the command's content appearance. This includes status information determinative of the command's state (enabled/disabled), its name, its associated graphic, and whether its appearance is currently valid. Each of these were initialized when the command was created. The invention creates a command including an object's data structure containing a command sequence. The command is added to a list of commands, and initialized as an invalid appearance. Later when the command is selected, the appearance state is recomputed based on the system state.
Patent CA-2147676-A1 (CA)
Title: Sequential blasting system
Inventor: RITTER HEINZ
IPC: F42D1/055
Filed: 1995-04-24
Abstract: A sequential blasting system for use in particular in mining comprises a plurality of detonator stages S1, S2, ..., each of which contains  a series  circuit  consisting of  a thyristor T and a detonator means ZE, said series circuit be-ing interposed between two supply leads A, O; B, O. The sig-nal voltage for the thyristor T in each stage is derived solely from the switching state of the thyristor T of the preceding stage.  This causes activation to be transferred from stage to stage independently of the detonator means ZE, in particular irrespectively of whether or not a detonator has been attached and whether or not this detonator becomes highly resistive or not as it should upon being activated. This eliminates the errors that have occurred in known cir-cuits. Upon firing the blasting system, such errors can cause the  detonation to occur not only at  the  first  detonator stage, but simultaneously at a location where a detonator is missing as well. In other cases,  such errors terminate the detonating sequence at the site of an improperly functioning detonator and induce impermissible delays and thus consider-ably shorten the length of time between the electrical se-quence and the blast, thus causing undesirable changes in the shock wave caused by the blasting sequence.
