Abstract: The process and apparatus for tension stringing a conductor through above-ground supports uses a length of rope affixed to the conductor wound on the tensioning machine and pulled by the puller machine. Each of the first and second stringing apparatuses includes an onboard control system which controls each of the first and second stringing apparatuses in pulling mode or in tensioning mode. Each of the first and second stringing apparatuses includes a motor/regenerative brake or other means of inducing tension into the conductor. Each of the machines includes a wireless transceiver which is hard-wired to said onboard control systems. A first operator resides on the puller machine and selects the machine as a puller machine operating in pulling mode using an onboard control system. An observer resides on the tensioner and selects the second machine to be the tensioner.

Abstract: An improved roll bending system is described for the work rolls and intermediate rolls in a six high mill. New bending blocks apply improved roll bending forces to the roll chocks, and additionally, are designed to move vertically and rotate, which provide important benefits to maintenance and enhance the rolling operation. Additionally, important related details to the mill operation and bending blocks provide operational improvements during roll changing.

Abstract: An electrocautery unit includes a light source that may be molded to the electrocautery tip during the manufacturing process. The light source may be chosen by the manufacturer that will work with the electrical system used to power the electrocautery. The light source may be monopolor (on demand lighting when the user initiates the electrocautery), bipolar with constant illumination, or separately wired from the electrocautery device and using its own power supply and on and off switch. The shape and/or angle of the light source may be determined by the function desired by the user. A broad angled light source could be used for large areas needing homeostasis. A narrow light could be used to direct illumination directly ahead of the electrocautery unit. The light source may be a light emitting diode (LED), as such a light source may be reusable through gas sterilization or a single use disposable item.

Abstract: A novel explosion-proof motor, which includes an integrated explosion-proof housing. In some embodiments, the integrated explosion-proof housing contains various electronic components that support the operation of the explosion-proof motor. To this end, embodiments of the explosion-proof motor may include a stator having an end ring, a plurality of stator coils extending from a core, and an end bracket fitted to the stator end ring to form a generally circumferential flame path. The end bracket may include an inner volume on one side thereof for receiving the stator coils, and an integrated explosion-proof housing on the other side. To reduce the number of explosion-proof seals, the inner volume and integrated explosion-proof housing may share the circumferential flame path to enclose their respective volumes.

Abstract: A novel explosion-proof motor, which, in certain embodiments, features a housing with flame paths between various joints in the housing. These flame paths may contain and cool hot gases and flames produced by a detonation within the housing. In certain embodiments, the explosion-proof motor includes a stator having a plurality of laminations and an end ring. The end ring may have a generally circumferential surface to interface with other components of the housing. The explosion-proof motor may also include an end-bracket having a second generally circumferential surface configured to mate with the end ring. The mating circumferential surfaces of the end-ring and the end-bracket may form a flame path to prevent the propagation of an internal detonation.

Abstract: A method for matching an acoustic load and an acoustic driver in a resonant acoustic system, and the acoustic system so formed. The load and driver may be independently designed. The invention provides, inter alia, a matching volume positioned between the acoustic driver and load that is substantially greater than a stroke volume of the driver. The matching volume is sized such that, in combination with the moving mass, the characteristic stiffness of the acoustic driver and the characteristic load impedance, a resulting pressure wave produces an operating resonant frequency substantially equal to the preferred operating frequency of the load. Alternatively, or in addition thereto, a stroke volume of the acoustic driver can be adjusted.
