Abstract: ABSTRACT A machine and method are disclosed for securing a loop of thermoplastic strap around an article so that two overlapping portions of strap are bonded together. One form of an apparatus in the machine has a strap engaging weld pad with spaced-apart, parallel strap-engaging ribs for effectively making a friction-fusion weld in thin film strap.  Another form of the apparatus in the machine includes a rack gear associated with a weld pad and engaged with an arc of teeth on a torsion bar for utilizing the torsional oscillation kinetic energy to reciprocate the weld pad along a linear path of motion. Another form of the apparatus in the machine includes a strap carrier chain for forming the strap in a loop about an article and the chain may include a resilient lug positioned between each pair of adjacent cross pins in the chain.  Another form of the apparatus in the machine includes 1) means for reciprocating an anvil between a retracted position and an extended position below an article, 2) grippers and cutters connected with a linkage system to move the grippers and cutters between a closed position against the anvil and open position away from the anvil, and 3) carriages for moving the cutters and grippers from a retracted position to an extended position independently of the anvil.  All of the forms of the apparatus may be used separately and independently of each other in various other types of strapping machines.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention provides a filter comprising a metal case associated with a metal base forming a guide of any section but under cut-off, that is to say which does not allow guided propagation.  Cylindrical dielectric rssonators are in contact with the metal securing base and the resonators resonate then in the TMO10 mode.  For frequency tuning of the filter, the distance between the bottom of the case and the ends of the dielectric resonators supported by the base is variable.  The invention applies more especially to tuneable band-pass filters.

Abstract: FIBER OPTIC PLENUM CABLE               ABSTRACT OF THE DISCLOSURE        A fiber optical cable is designed for good thermal stability over a broad temperature range and with low flame-spreading and low smoke-producing characteristics for interior use, such as in plenum areas.  Optical fibers are each buffered with a layer of resilient polymeric material with a broad dynamic temperature range.  A nonburning serving shields the buffer layer from flame, and a jacket of polymeric material surrounds the serving.  The jacketed cables are bundled with a like number of strength members formed of a material with a coefficient of thermal expansion roughly matched to that of the optical fibers.  The strength members and jacketed fibers are wrapped in tape, and the bundled components are tightly jacketed by a tube of polymeric material.  The jackets and outer tube are formed of low flame-spreading, low smoke-producing fluorocarbons, whereby the cable meets U.S. requirements for plenum use.  The strength and thermal stability provided by the strength members maintain the light-transmitting characteristics of the optical fibers over the broad temperature range.

Abstract: ABSTRACT   A system for measuring the coefficient of friction between the bottom two sheets of the stack. The vacuum corrugation feeder tray is rigidly mounted and supports a stack of sheets resting at one end of the tray against a movable backstop. An air knife provides air pressure between the bottom sheet from the rest of the stack. The stack of sheets is forced up the tray by the backstop and allowed to slide back down the tray when the backstop is moved. The coefficient of friction between the stack and the bottom sheet is determined by the acceleration of the stack as it moves back down the tray. The coefficient of friction is then used to control the amount of air pressure from the air knife until an optimum coefficient of friction is achieved.
