Abstract: A device for covering and uncovering an opening of a container for a truck o r trailer has a pair of pivotal arms (30) that are mounted along opposite sides of the container with each arm having an outer and inne r end. A cross-member is mounted between the outer ends of the pivotal arms so that the pivotal arms are coupled together. The inner en d of each arm is mounted to the truck or trailer at a pivot point so that arms can be pivoted between a starting position and an end position. A flexible covering is coupled to the outer ends of the arms and is drawn or withdrawn over the opening when the arms are moved to the en d and starting positions. The arms are moved by providing a convex arcuate contact portion (44) located about the pivot point of the arm. A piston rod and cylinder (52) are mounted adjacent to the contact portion. An arm engagement member is coupled to the piston rod and cylinder and engages the contact portion of the arm so that linear movement of the arm engagement member causes the arms to pivot.</SDOA B>

Abstract: Open circuit faults in a cable are located by applying a step function DC voltage to one end of a conductor along the cable, for example the metallic shield along a fibre optic cable. The DC current along the conductor is measured over a sampling period and integrated to determine the capacitive charge on the cable. The distance between the end of the conductor and the open circuit fault is computed from the calculated charge and the known capacitance per unit length of the conductor.      The DC current in the conductor is measured by sampling the current at a predetermined sampling frequency. The sampling frequency is preferably an integral multiple of the local AC mains power frequency, either 60 Hz or 50 Hz to eliminate the effect of induced AC voltages in the calculations. To eliminate the effects of a resistive fault, the method may include the steps of determining the conductor resistance and subtracting from the calculation of capacitive charge a DC  fault current that is calculated from the conductor resistance and the DC voltage. An apparatus for carrying out the method is also disclosed.
Patent CA-2317175-C (CA)

Granted: 2006-11-28
Abstract: A method and device for synchronizing the motion between a chassis (master) motor and one or more enclosure feeder (slave) motors in an envelope inserting machine. The motion profile of one motor can be varied with time independently of the others. The displacement mapping method uses encoders, such as optical encoders, to obtain the displacement of each of the associated motors as a function of time. From the actual displacement of the master motor, an electronic computation device or process is used to calculate the theoretical displacement of each slave motor according the motion profile of the slave motor. The theoretical displacement is then compared to the actual displacement. If there is a discrepancy between the theoretical and the actual amount, then the motion of the slave motor will be adjusted so as to eliminate that displacement discrepancy.

Abstract: This invention is directed to making chemical derivatives of carbon nanotubes and to uses for the derivatized nanotubes, including making arrays as a basis for synthesis of carbon fibers. In one embodiment, this invention also provides a method for preparing single wall carbon nanotubes having substituents attached to the side wall of the nanotube by reacting single wall carbon nanotubes with fluorine gas and recovering fluorine derivatized carbon nanotubes, then reacting fluorine derivatized carbon nanotubes with a nucleophile. Some of the fluorine substituents are replaced by nucleophilic substitution. If desired, the remaining fluorine can be completely or partially eliminated to produce single wall carbon nanotubes having substituents attached to the side wall of the nanotube. The substituents will, of course, be dependent on the nucleophile, and preferred nucleophiles include alkyl lithium species such as methyl lithium.
