Apparatus and method for inspecting the finish of transparent containers, particularly glass containers, which include facility for directing diffused light energy laterally through the container finish as the container is rotated about its central axis. A camera includes a plurality of light sensitive elements disposed in a linear array angulated with respect to the container axis to view the external and internal finish wall surfaces, the latter through the open container mouth. Individual elements of the camera linear array are sampled by an information processor at increments of container rotation, and corresponding data indicative of light intensity at each element is stored in an array memory as a combined function of element number and scan increment. Such data is compared following completion of container rotation to standard data indicative of acceptable container finish, and a reject signal is generated if such comparison exceeds an operator adjustable threshold.

Inspection of container finish

There is disclosed an apparatus and method of recovering a portion of the waste heat produced in a high temperature industrial process, such as a glass melting furnace, where the furnace has at least a pair of regenerators which are alternately used to preheat the combustion air and serve as hot exhaust heat storage means. The hot exhaust gases from the process are passed through a heat exchanger where the heat is indirectly transferred to the clean compressed air at 100 psi from the compressor of a Brayton cycle energy recovery system with the hot compressed air being expanded in a high performance turbine. The exhaust from the turbine will be at atmospheric pressure and at a temperature between 750.degree. F. and 900.degree. F. This turbine exhaust is fed to the opposite side regenerator as clean preheated combustion air. One embodiment is directed to the use of a regenerator that is made up of primary and secondary sections with the exhaust to the heat exchanger being taken from a connection between the sections whereby the glass melting furnace is not effected whether the Brayton cycle system is in operation or the secondary is functioning without the Brayton cycle energy recovery system.

Cogeneration from glass furnace waste heat recovery

A high voltage electric power transmission line having an electrical power carrying capacity of 50 megawatts or more. An electrical power conductor is contained within a substantially rigid dielectric casing formed of a plurality of elongated tubular glass casing sections hermetically bonded together linearly end to end forming a continuous elongated casing around the conductor. The casing is loosely contained in an outer duct which permits lateral movement of the casing in the duct but places a maximum limit on such movement.
