Abstract: Disclosed are overvoltage arresters comprising a columnar arrangement of arrester elements, insulating elements and conducting elements. The elements are arranged to provide a current flow in at least one plane extending transversely to the columns. The conducting frame elements connect other elements thereto which elements extend both axially and transversely of the columns. For an arrester including n conducting frame members per plane, n-1 arrester elements are arranged per plane of the columnar structure. The current connection between adjacent plane is made by an arrester element or by a conducting member preferably such that opposite current flows are obtained in adjacent planes. Overvoltage arresters according to the invention are particularly suited for using voltage-dependent resistors of the zinc oxide type alone or in conjunction with spark gaps. The columnar structure may be disposed in a customary insulating gas such as nitrogen or in a gas with particularly high insulating strength such as SF6.

Abstract: Method and apparatus for injection compression molding of thermoplastic parts. A preferred apparatus (100) includes a platen assembly 106, a toggle clamp assembly 102, a screw injection assembly 101, a hydraulic system suitable for providing power to the toggle clamp assembly 102 and the screw injection assembly 101, and a control system 88 for operatively controlling the various hydraulic devices associated with the molding apparatus. The platen assembly 106 provides for a plurality of variable-volume mold cavities 7. In one embodiment, enlarged mold cavities 7 receive plasticized resin from the screw injection assembly 101, and compression of the injected resin is provided by the toggle clamp assembly 102. In another embodiment, the platen assembly 106 includes a floating die assembly wherein pressure created by injected resin causes die inserts 5 and support pillars 15 to slide relative to a molding plate 74. Compression in this embodiment is also preferably provided by the main toggle clamp assembly 102. Preferably, the toggle clamp assembly 102 provides multiple-stage compression of the resin to first redistribute the resin and vent the cavities and, second, compress the resin to compensate for cooling-induced shrinkage thereof. In the multiple cavity embodiment, because all cavities 7 are equally compressed simultaneously, control of the molding process and balancing of the mold are readily accomplished. The method and apparatus are particularly well suited for molding optical lenses and disks. Printed circuit substrates can also be molded thereby.

Abstract: In order to start or recommence spinning of a yarn in a friction spinning apparatus, in the course of starting of spinning or piecing after a yarn break, by means of a fiber transport duct, fibers separated by an opening device, are delivered to a rotating friction spinning drum and twisted to form a twisted fiber structure. When the twisted fiber structure has reached a substantially predetermined diameter, the twisted fiber structure is moved by an airstream delivered from a pressure air infeed channel towards and into a guide tube and from that location, into the convergent space of rotating withdrawal rolls. The twisted fiber structure is entrained at production speed by these withdrawal rolls and is delivered to the diverging or outlet side of the withdrawal rolls to a suction device placed in readiness. This suction device can transfer the formed yarn following the twisted fiber structure to the succeeding or downstream elements provided for further processing.

Abstract: In the shear mode piezoelectric transducer for an ink jet system described in the specification, a piezoelectric plate is polarized parallel to the plane of the plate and in directions extending away from the center of the pressure chamber with which the transducer is used, and electrodes mounted on opposite surfaces of the plate impose electric fields orthogonal to the direction of polarization. The resulting shear motion of the transducer decreases the volume of the pressure chamber, ejecting a drop of ink from an orifice communicating with the pressure chamber. The piezeelectric plate used in the transducer is prepared by imposing electric fields within the plate in the direction parallel to the plane of the plate between electrodes mounted on opposite sides of the plate in the central region of the pressure chamber and electrodes mounted on opposite sides of the plate in the peripheral regions of the pressure chamber.
