    Abstract: This invention comprises a vibration sensor for detecting engine knock. The sensor has a tuning mechanism which is mechanically resonant with a preselected vibrational frequency. The resonating movements of this tuning mechanism are adapted to apply varying stress to an associated magnetostrictive element. A magnetic biasing element imparts a magnetization to the magnetostrictive element and a detecting means is associated with the magnetostrictive element for detecting changes in the magnetization caused by the varying applied stress.

    Abstract: A temperature-sensitive switch is provided with a resilient movable cantilever composed of amorphous ferromagnetic material having a Curie point. The cantilever is adapted to carry a first contact member. A second contact member is disposed adjacent the first contact member for at least intermittently establishing electrical contact with the first contact member. A magnet is associated with and adapted to bias the cantilever to a first position that establishes electrical continuity between the first and second contact members. The cantilever is transformed from a ferromagnetic phase to a paramagnetic phase when its temperature exceeds the Curie point, whereby the cantilever assumes a second position in which the electrical conductivity is interrupted. The switch is lightweight, compact, economical to manufacture and reliable in operation.

    Abstract translation: 温度敏感开关设置有由具有居里点的非晶铁磁材料组成的弹性可移动悬臂。 悬臂适于承载第一接触构件。 第二接触构件设置成与第一接触构件相邻,用于至少间歇地建立与第一接触构件的电接触。 磁体与悬臂相关联并适于将悬臂偏置到在第一和第二接触构件之间建立电连续性的第一位置。 当悬臂的温度超过居里点时,悬臂从铁磁相转变为顺磁相,由此悬臂呈现中断导电性的第二位置。 该开关重量轻,结构紧凑,制造经济,操作可靠。
