摘要： A controller for a spot-welding machine compares the temperature evolution at a site at which a spot weld is being made to a standard thermal history stored in a digital read/write memory in controlling the welding current for the weld. Standard thermal histories can be generated and written into the memory as needed by an operator of the welding machine to take into account changes in operating conditions. The temperature evolution of the spot-welding operation is monitored by detecting radiant energy whose intensity provides a measure of a temperature of the weld. Phosphorescent radiation from a thermographic phosphor located in a welding tip of the welding machine and thermal infrared radiation are preferred for monitoring the temperature evolution of the spot-welding operation.

摘要： An apparatus for inspecting a device made up of a plurality of different infrared radiating elements includes an optical head which is moveable along X-Y coordinates above the fixed device to sequentially scan the infrared radiating elements. A laser beam source is operatively connected to the moveable head for injecting thermal energy into the infrared radiating elements and an infrared detector is provided for sensing the infrared radiation emanating from the elements. The infrared detector may be mounted directly on the moveable head or in a remote location wherein the detector would be connected to the moveable head by a flexible optical fiber. A second moveable head may be located on the opposite side of the device so that thermal energy from the laser source may be injected into opposite sides of the infrared radiating element.

摘要： Control of spot weld quality is effected by observing the progress of heat generation within the weld and initiating automatic corrective action if the heating rate is initially too high or too low. A flexible optical fiber bundle has one end located in the welding tip and the other end optically coupled to an infrared detector. Due to the excellent thermal conductivity of the copper material of the welding tip, thermal energy is conducted very rapidly for a short distance into the tip during the weld formation so that the infrared detector produces an output signal proportional to the weld temperature. This signal is sampled and compared with a previously-recorded signal corresponding to the heating rate that produced a good spot weld in the material being welded.

摘要： A clock is provided having a luminous digital display. The clock is enclosed in a housing having a glass covered display face. A stationary light source is provided within the housing. The first end of each of a plurality of optical fiber light conductors are mounted in annular concentric bands on a mounting board inside of the clock. The second end of each of the optical fiber light conductors are arranged in a pattern on the display face to indicate time. The light guides receive light from the light source and cause illumination of the display. Filters are mounted on arms which are in turn rotatably attached to the output shafts of a clock motor. The arms are disposed in such position that the filters come between the light source and the first ends of a group of light conductors as the filters rotate, filtering the light received by that group of conductors, and creating a colored display of time information at the second ends.A special arrangement of the light guides produces a simulated pendulum effect. An arrangement of a stationary filter disc in register with a rotating filter disc utilizes a vernier principle to allow use of a lesser number of output shafts of the clock motor. The display produced by the stationary and rotating discs is a moire pattern of light intensities which streaks across the time scale.
