In a method of joining a solidifiable liquid polymeric material to a solid material to produce a solid article, the solid material is contacted with the liquid polymeric material at an interface. Ultrasonic energy is applied so that the energy reaches the interface between the contacting solid material and liquid polymeric material. A joint is formed at the interface by allowing or causing the liquid polymeric material to solidify, to produce a solid article comprising the solidified polymeric material joined to the solid material.

Methods of joining polymers using ultrasonic energy

An integrated, automated system for terminating an optical fiber with an optical connector which includes a process for preparing adhesive for injection into an optical connector, an apparatus and process for injecting adhesive into an optical connector, an apparatus for inserting a fiber optic cable into an optical connector, and a process for curing an adhesive following insertion of optical fiber into the optical connector. Devices and methods that utilize vibratory or wave energy throughout the assembly process are also provided, as are feedback modules that enhance the accuracy and efficiency of the system.

System for terminating optical cables

Acoustic energy is used to detect and identify objects buried in soil by imaging acoustic energy reflected from the soil and buried objects. Acoustic energy is injected into soil at an oblique angle relative to the surface of the soil, reflected and received. Signals representative of the reflected energy are processed to generate image signals used to generate images representative of the reflected energy. Objects buried within the soil are identified by viewing the images. In one embodiment, obliquely oriented acoustic energy signals are carried from a source to a soil sample by a first duct and reflections of that energy are carried to a receiver within an adjacent second duct. The ducts acoustically isolate the source from the receiver. A beveled end of the first duct and the second duct are supported above the soil sample for noncontact operations. In another embodiment, an acoustic energy source is obliquely supported upon and forced into engagement with soil in a reservoir. The reservoir is placed in contact with soil to be probed to effect a soil 'impedance match' for oblique injection of acoustic energy into the soil. An acoustic energy receiver contacts the soil adjacent to the reservoir to receive acoustic energy reflected from the soil and objects buried within the soil. Pulse compression increases penetration depth. To compensate for soil attenuation characteristics, frequency-swept sinusoidal acoustic energy pulses are preferably amplitude modulated to have an exponentially changing envelope.

Method and apparatus for acoustic energy identification of objects

Apparatus and methods are disclosed for acoustically detecting different conditions of boiling occurring within a liquid and developing useful control signals correlated to the detected boiling condition. Distinctions are made between no-boiling, sub-cooled boiling, and full or rolling boiling conditions.
