摘要： There is disclosed a fiber optic waveguide which is particularly suited for infrared radiation transmission at extended wavelengths. The core of the waveguide is fabricated from heavy ionic compounds selected from metal halides in order to achieve such extended infrared transparency. While it is impossible to prepare these materials into optical fibers using conventional fiber drawing techniques, the present invention teaches how such materials may be prepared into optical fibers using an extrusion process at elevated temperatures and high pressures.

摘要： A method of forming a low-cost drop cable (10) is disclosed. The method includes providing a protective cover material (352) having an extrusion temperature of 140° C.≦TE≦160° C. The protective cover material is extruded through a die (420) having a single aperture (424) that defines the cable's elongate cross-sectional shape. The extrusion process involves covering first and second strength members (30) on either side of at least one optical fiber (50). The combination of the low temperature of the extrudable protective cover material and the elongate shape of the single die aperture cause the formation of an oval cavity (20) within the extruded protective cover material. The oval cavity has major and central axes (A1, AC) and surrounds the at least one optical fiber. The strength members lie along the cavity major axis. Tensioning the strength members during extrusion and then releasing the tension causes the drop cable length to be reduced. This gives rise to an excess fiber length, which adopts a serpentine configuration substantially in a plane (PF) defined by the major and central axes (A1, A2) of the oval cavity.

摘要： A hydraulic adjusting system is provided for the continuous adjustment of the vibration amplitude of a rotating eccentric element. The hydraulic adjusting device includes a piston in a single acting cylinder. A piston connecting rod extends through the cylinder and is rigidly journalled axially inside the piston. One end of the rod is rigidly connected to a drive shaft of the eccentric element and the other end to a power source for rotatably driving the eccentric element. The system provides for continuous adjustment of amplitude vibration and, since the vibration amplitude is directly proportional to the hydraulic pressure acting on the piston, the system also facilitates setting and monitoring of such vibration amplitude.

摘要： A connecting device for a pair of light waveguide cables with each cable having an optical fiber which is loosely enclosed in a tubular sheath characterized by a joint between the ends of the pair of sheaths of the two cables being bridged by an appropriate tube which is fixed to the ends of the two sheaths and does not require any special housing such as bushing and the like. The tube may be an inner tube, which is inserted into the interiors of the pair of tubular sheaths being connected together or an outer tube which is fixed onto the tubular sheaths. In another embodiment, both an inner and outer tube are utilized. A length adjustment of the optical fiber within the pair of tubular sheaths can be carried out by virtue of a helical arrangement of the optical fiber and the bridging which is provided by the one or more tubes.

摘要： A cable includes a guide element and a signal line. The guide element extends flatly on a guide plane, and the signal line is guided along a winding path on the guide plane by the guide element. The signal line has multiple bends on the guide plane. In particular, the cable is suitable for use under high stretching loads by virtue of the winding course of the signal line. The cable is simultaneously particularly space-saving in that the line is guided solely within the guide plane. A method for producing the cable is also provided.
