摘要: A temperature sensor is provided comprising a conductor having a low-melting-point, a fibrous insulating layer adjacent the low-melting-point conductor and separating it from a second conductor. An oscillator applying a pulse signal to the sensor and a receiver receiving the pulse signal through the sensor can detect changes in the signal wave form due to melting or distortion of the low-melting-point conductor. The specific temperature to be sensed can be preset by providing preheating of the sensor, as by Joule heating, by passing a current through the low-melting-point conductor.

摘要: Means are provided for radiating electromagnetic waves from a receiving end zone of a dielectric line for transmitting electromagnetic waves without the need for a metal horn antenna or a metal waveguide, and matching problems are thereby substantially avoided. Said means are provided by shaping the end of the line to specified contours, by varying the dielectric constant of the material of the line in a gradient longitudinally near the end zone of the line, and by arranging a reflecting mirror or lens to receive the waves emitted from the line. This waveguide is useful in wireless communications, radar transmission and similar applications.

摘要: A detector for detecting leaks of a corrosive liquid such as strong acids or bases is provided comprising a light guide core having a covering which generates heat upon contact with the liquid to the detected, thereby changing the light transmissivity of the light guide, which change can be measured. The covering comprises a porous polymer having a salt within its pores such as an ammonium salt which dissolves in the liquid to be detected and generates heat thereby.

摘要: A dielectric sheet material useful in electronics applications is provided. The material preferably is porous, expanded polytetrafluoroethylene (PTFE) having a plurality of through-holes. The walls of the through-holes are solid, sintered PTFE which impart a high degree of compressive strength to the otherwise highly compressible porous PTFE. The through-holes having solid walls may be formed in the material by a laser or by other means.

摘要: A coaxial cable and a bare wire are aligned in parallel relationship and affixed within insulation covers which have openings therein so as to partly expose both the bare wire and the outer conductor of the coaxial cable at the atmosphere, forming a leak detecting sensor. By the use of resistance meters, the core wire of the coaxial cable is utilized to detect both the presence and the location of a leak.
