Title: Apparatus and method for installing line in conduit

IPC: H02G1/08

Granted: 1983-11-01
Abstract: APPARATUS AND METHOD FOR INSTALLING LINE IN CONDUIT Abstract of the Disclosure Pull lines are utilized for installing electric wires in electrical conduit between junction boxes by attaching a pull line to the near end of a hollow-core line carrier having its forward end closed by a collapsible bag-like member of highly flexible plastic film or fabric. The bag-like member has a cross-section greater than that of the conduit and is inflatable through the trailing end of the line carrier so to maintain a yieldable continuous contact with the conduit interior wall about the line carrier as the carrier is moved through the con-duit in response to a pressure differential created at one end of the conduit. In one form, the line carrier is a tubular sleeve of rigid or shape retaining material to which the pull line to be installed is attached; and, in a second form, it is a roll of the line itself which is disposed within the open end of the bag-like member. In a modification of the first form, the bag-like member is collapsed for storage within the sleeve. -1-

Abstract: ABSTRACT OF THE DISCLOSURE         A rotary sliding closure unit for use in a liquid melt container extends inwardly through the jacket of the container and into the lining thereof to selectively block and unblock a pouring opening of the container.  The unit includes a stationary refractory plate positioned within the lining and having there-through a flow passage in communication with the pouring opening, and a rotary refractory plate positioned in sliding abutting contact with the stationary refractory plate and having there-through at least one flow passage to be selectively moved into and  out of alignment with the flow passage of the stationary refractory plate.  The two refractory plates have complementary abutting relative sliding surfaces located within the interior of the jacket of the container.  A stationary tube member extends through the jacket and into the lining and has an inner end grasping the  stationary refractory plate.  An intermediate member fixes the rotary refractory plate, and a rotary tube member extends through the jacket coaxially within the stationary tube member.  The intermediate member is fixed with respect to the inner end of the rotary tube member to rotate therewith, but to enable relative axial movement therebetween.  The intermediate member is axially urged away from the rotary tube member to thus urge the rotary refractory plate into pressure contact with the stationary refractory plate.

Abstract: APPARATUS AND METHOD FOR BREAKING SAND              FREE FROM A PATTERN POCKET IN A MOLD                   Abstract of the Disclosure This invention relates to an apparatus and a method for breaking sand free from a pattern having a deep bore.  The apparatus is designed to support the pattern on a pattern plate having an aperture coaxially aligned to the deep bore.  A stripper block is movably positioned within both the apertures and the bore and is spring biased to a stationary back plate which is supported to the pattern plate.  As sand is packed about the pattern and into the bore, the stripper block is forced downward toward the back plate.  After the sand is set forming a sand mold, the pattern is removed.  Simultaneously, the spring exerts a force on the stripper block causing it to move back to its initial position whereby the sand is broken free from the inside surface of the deep bore.

Abstract: APPLIANCE STRAIN RELIEF                  ABSTRACT OF THE DISCLOSURE    In a portable electric appliance that is cord connected to internal electric terminals by multiple conductors as in an iron, an improved strain relief between the cord and appliance comprises a housing chamber at the cord entrance with a cover over the chamber enclosing the conductors.  A formed pocket in the chamber has a straight rear wall and a non-parallel sloped wall both molded as part of the housing and spaced from the rear wall, the two angling toward the cord entrance.  A boss in the pocket is formed on the rear wall extending toward the sloped wall to define a pair of spaced conductor channels and also a central anchor to secure the cover.  A separate barbed wedge-shaped member with barbs directed away from the cord entrance fits between the pocket walls to straddle the boss and slide in the channels. An elongated aperture provides for adjustable and aligning securement to the boss of the wedge between the cover and rear wall whereby the barbs clamp the conductors in the channels, regardless of their size, against any pull force on the cord such that the wedging action is continuously increased for strain relief between the cord and terminal by a simple three-piece construction.

Abstract: ABSTRACT       The method and the apparatus for determining the substance amount of quantities of fibres or for determining the substance cross section of slivers (5) uses the elastic or dynamic properties of a fibre quantity.  In a first variant, a resonance system comprising a spring and mass is formed, the fibre quantity or the sliver acting as the spring.  Thus, the resonance frequency is a measurement for the density of the fibre quantity, or the sliver.  In a second variant, in the case of a sliver, the sliver (5) which is guided in a tube or in a funnel (6) is exposed to mechanical, pulses or oscillations which are propagated in the sliver with a certain damping and with a velocity which depends both on the density of the sliver as well as on the modulus of elasticity thereof.  The transit time of these pulses or oscillations thus produces a measurement for the substance cross section of the fibre quantity or sliver.

Abstract: IMPROVED SENSING AND WELDING ARRANGEMENTS          FOR MANIPULATOR WELDING APPARATUS                      Abstract Manipulator apparatus with weld seam tracking capabilities is provided with a sensing  hand attached to the manipulator arm.  The manipulator apparatus traverses a taught welding path on a workpiece to determine any deviation between the workpiece path and the taught path.  The sensing hand includes a projection unit for projecting an optical slit pattern onto the workpiece.  The sensing hand  also includes a path sensing unit including an objective lens and a fiber optic cable for receiving by reflection from the workpiece the projected optical slit pattern.          The fiber optic cable is connected to a camera located remotely from the sensing hand.  The image received by the camera is utilize by the manipulator apparatus during a sensing step to determine the deviation between the path traversed by the manipulator during sensing and the actual  workpiece path.   The devi-ation is then utilized to calculate the workpiece path datafor welding the desired weld seam with a welding hand attached to the manipulator arm.  In a first arrangement, a welding hand and sensing hand are provided at a hand holder station at the work station adjacent the workpiece.  The manipulator auto-matically and selectively exchanges the hands at the hand holder station in accordance with the particular programmed operation to be performed.  In another arrangement, the manipulator arm carries a welding hand and a sensing hand.  The sensing hand is movably controlled by the manipulator apparatus between an operative sensing position and an inoperative welding position.
