    • A magnetic theft detection system marker is adapted to generate magnetic fields at frequencies that (1) are harmonically related to an incident magnetic field applied within an interrogation zone and (2) have selected tones that provide the marker with signal identity. The marker is an elongated, ductile strip of amorphous ferromagnetic material having a composition defined by the formula Fe.sub.a Cr.sub.b C.sub.c P.sub.d Mo.sub.e Cu.sub.f B.sub.g Si.sub.h where "a" ranges from about 63-81 atom %, "b" ranges from about 0-10 atom %, "c" ranges from about 11-16 atom %, "d" ranges from about 4-10 atom %, "e" ranges from about 0-2 atom %, "f" ranges from about 0-1 atom %, "g" ranges from about 0-4 atom % and "i" ranges from about 0-2 atom %, with the proviso that the sum (c+d+g+h) ranges from 19-24 atom % and the fraction [c/(c+d+g+h)] is less than about 0.84.

    • The effectiveness of thermal insulation of barriers, such as walls, floors, or ceilings of a residence, is assessed by measuring the effective values of insulation or R values, of thermal barriers. Suitable devices and procedures for utilizing such devices are provided. The R values so measured can be compared with those suggested for economic insulation in such sources as government publications to determine the desirability of augmenting existing insulation.The device comprises a holder and a temperature sensor and indicator means supported on a support slidably mounted in the holder. In one embodiment, a single device combines measurement of thermal insulation and comparison with suggested values for economic insulation. A direct measurement of whether installed insulation is adequate is thus provided.
    • 通过测量隔热层的绝热或R值的有效值来评估隔热层隔热效果,例如住宅的墙壁,地板或天花板。 提供了适用于使用这种装置的装置和程序。 可以将这样测量的R值与政府出版物等来源的经济绝缘建议进行比较,以确定增加现有绝缘的可取性。 该装置包括保持器和温度传感器以及支撑在可滑动地安装在保持器中的支撑件上的指示器装置。 在一个实施例中,单个设备将热绝缘测量与建议的经济绝缘值进行比较。 因此提供了安装绝缘是否足够的直接测量。
