摘要： A pulser unit is composed of two high strength magnets (30, 32) spaced apart from one another and establishing an intense magnetic field therebetween. Forward faces (30f, 32f) of the two magnets (30,32) establish a working surface for the pulser unit. A Wiegand wire module consisting of a Wiegand wire segment (34) around which a pickup coil (36) is wound is mounted in the pulser unit immediately behind the working surface of the pulser unit and adjacent the sides of the two spaced apart magnets (30,32). The magnetic field is sufficiently strong to determine the state of the Wiegand wire (34). When a low reluctance element (20) is brought adjacenttothe front of the working surface, the field is substantially distorted and the field to which the Wiegand wire (34) is subjected changes materially. The result is that the Wiegand wire (34) switches state and the substantial rate of change of the flux in that switching of state is sensed by the pickup coil (36) to provide an output pulse. Similarly, removal of the low reluctance element causes the field to revert so that the wire switches state back thereby inducing an output pulse in the pickup coil (36). The pulser can conveniently be kept stationary while the actuating low reluctance element (20) is moved past the working face of the pulser.

摘要： A pressure actuated switch is provided in which one face of a diaphragm (22) engages a metal contact plate (20) which has a pair of integral contact areas thereon or a pair of contacts (17,18) fused thereto for engagement with contacts (15,16) on the ends of a pair of terminal posts (13,14) moulded in a plastic housing part (30). The contact plate (20) also has a central deformation (40) disposed between the contacts (15,16) thereon and engaged with a spring metal strip (37) of arcuate cross-sectional configuration, one or more additional strips (38) being optionally provided.

摘要： A read head for a Wiegand type wire. The read head establishes an asymmetric field to which the wire is subjected. A setting magnet at a first position establishes a sufficiently strong positive field to set the core and shell of the Wiegand wire in a first confluent state. At a second position, the field is sufficiently negative so as to assure that the core switches state thereby establishing a reverse state for the wire. The field does not go strongly negative and thus the state of the shell is not reversed. At a third position, the field becomes sufficiently positive so as to cause the core to reserve its state again thereby switching the wire from its reverse state to its confluent state. This particular switching occurs in close proximity to the pickup coil thereby providing an output pulse in response to the switch of state of the wire from reverse state to confluent state.
摘要翻译： Wiegand型电线读头。读取磁头建立电线所对应的不对称磁场。在第一位置处的设定磁体建立足够强的正场，以将第一汇合状态的韦根线的芯和壳设置。在第二位置，场足够负，以确保铁心切换状态，从而建立线的反向状态。该领域并没有强烈地消极，因此壳体的状态不会逆转。在第三位置，磁场变得足够正，从而使磁芯再次保留其状态，从而将电线从其反向状态切换到其汇合状态。这种特定的切换发生在靠近拾取线圈处，从而响应于线的状态从反向状态转换到汇合状态而提供输出脉冲。
