Abstract: TUBE WITH WEAKENED SIDE WALL SEGMENT AND METHOD FOR THE USE THEREOF IN PULLING CABLE                        ABSTRACT OF THE DISCLOSURE          An elongated cylinder is essentially comprised of a continuous side wall with a narrow weak wall segment along the length thereof for fracturing by the application of a small force to permit access to the interior of the cylinder along the fractured side wall.  The weak side wall segment is in the form of a very thin web section produced by grinding or in a molding operation which may additionally include the filling of the hollowed area of the side wall with a dissimilar material.  The article is used for cable placement, varmint protectors for tree trunks, protectors for wire harnesses, protectors for cable splices, and a mold for concrete.  The flexible feeder tube with a weakened longitudinal side wall is coupled at one end by a nozzle with an underground conduit while the remaining end of the feeder tube is located aboveground and joined with a lubricating collar that is split.  A supply of cable has a plain end and an end equipped with connectors joined to the conductors of the cable.  The plain end of the cable is joined with a pull-line that is fed from the conduit through the flexible feeder tube.  The plain end of the cable is then drawn into the feeder tube while lubricant is applied to the sheathing of the cable.  Pulling of the cable through the conduit is terminated before the end with the connector members contacts the feeder tube.  The lubricating collar is split and held together by fasteners which are loosened so that the collar can be removed from the cable and then the feeder tube is removed from the cable by severing the feeder tube along the weakened longitudinal side wall.  The feeder tube is light weight and removed laterally from the cable by the passage of the cable through the severed side wall of the feeder tube.

Abstract: ABSTRACT          A tractor draft sensing apparatus in which an elongated sensing shaft is supported in spaced fulcrum supports and carries a pair of draft links on its end portions located outward of the supports.  Draft force signals are provided by an elongate member which is attached at one end to the shaft, extends generally parallel to the shaft, and carries at its other end a follower which engages a cam and pivots the cam to give a signal proportional to shaft bending and hence to the draft forces applied to the shaft.          The elongate member also carries a separate follower which engages a guide surface on a guidance member to ensure that the elongate member moves relative to the shaft generally in a horizontal plane only during shaft bending.          The shaft may also be shaped so that its neutral axis between the fulcrum supports is displaced transversely of the shaft, generally in the direction of application of the draft force, relative to its neutral axis location within the supports.

Abstract: Case-2565 BELT TENSIONING ASSEMBLY FOR A CLOTHES DRYER.             ABSTRACT OF THE DISCLOSURE    A belt tensioning assembling for use in a clothes dryer positions a drive belt in tensioned relation about a rotatable drum and a drive pulley mounted within the dryer housing.  The belt tensioning assembly includes an idler pulley and a resilient mounting bar.  The mounting bar is preferably pre-stressed to maintain the belt in aligned tensioned relation about the pulleys.  The mounting bar includes a torsion arm member, a moment arm member, and a cantilevered positioning arm member onto which the idler pulley is rotatably mounted.  The moment member joins one end of the positioning member to one end of the torsion member.  The torsion member is secured in positioned load transfer relation with the housing.  This locates the positioning member in pre-determined spaced relation to the main axis of the drive pulley so that the idler pulley may be mounted thereon.  Once mounted, the idler pulley may be moved to receive the belt thereover so as to provide tension thereto.  In this position the idler pulley and drive pulley are substantially positioned in mutually aligned and parallel relation.  Previous belt tensioning assemblies include mounting supports for the idler pulley having many separate components taking on a relatively more complex and expensive construction than that of the mounting bar of the present assembly.

Abstract: PUFFER-TYPE CIRCUIT INTERRUPTER   ABSTRACT: A circuit interrupting device has a stationary contact. A movable contact is carried by a movable double-walled conductive tube which is telescoped and electrically continuous with a stationary tube. The tubes carry all of the current through the device. A piston carried by the stationary tube defines a piston-cylinder with the movable tube. When the movable tube moves to open the contacts, the piston-cylinder forces dielectric gas to and past the gap there-between. In a two-gap version of the device the stationary tube is also double-walled end carries a second stationary contact. A piston carried by the movable tube defines a piston-cylinder with the stationary tube. When a second movable contact jointly moves with the first movable contact to open the contact pairs, both piston-cylinders force dielectric gas to and past both gaps.

Abstract: 735.070-GKP             S P E C I F I C A T I O N     AIRGUN METHOD AND APPARATUS PROVIDING HIGH STRENGTH           AND HIGH PRESSURE CAPABILITIES     Inventor:   Stephen V. Chelminski ABSTRACT OF THE DISCLOSURE     Airgun method and apparatus are disclosed providing high strength, high pressure and large volume capabilities.          An integral high-strength cylindrical housing extends for the full length of the airgun and gives a sleek overall cylindrical configuration.  The components of the airgun advantageously are assembled within this cylindrical housing in two groups by sliding them in through the upper or lower end, respectively;  moreover, either of the groups of com-ponents can be removed independently of the other.   The components are pressed firmly together in place within the cylindrical housing by a strong screw-jack type of holding action, and tightening and locking apparatus is included on the airgun itself for enabling the mechanic to tighten and lock the holding means with enormous mechanical advantage.          Even though held together under great axial compression, the components are maintained in predetermined accurately regis-tered relationship with respect to the discharge ports in the cylindrical housing and with respect to each other by first and second internal shoulders located within the cylindrical housing near the discharge ports.  A reliable, rugged firing seal engages the periphery of the firing piston when it is in its closed position.   This firing seal is captivated in posi tion and does not involve any associated springs or movable members, and gas pressure is applied in a manner to increase the tightness of the sealing action.  This peripheral firing seal enables the firing chamber to have a wide-mouth so that discharged gas can flow out without restriction.  The rebound action of the shuttle near the top of its firing stroke is advantageously controlled and damped for reducing stresses, and the rebound control and damping effect can be adjusted.
