    • An encapsulated transformer includes a transformer coil assembly, a rigid core insert having an upstanding portion positioned within the hollow interior of the core and a base portion on which the core rests, and a thermoplastic rubber jacket that completely surrounds the transformer coil assembly and is bonded to the base portion of the core insert to provide a completely waterproof encapsulated transformer which is impervious to liquid and gasses that could be detrimental to the performance of the transformer. A method for producing such an encapsulated transformer includes placing a rigid core insert in a mold cavity of a mold, and positioning a transformer coil assembly in the mold cavity so that the transformer coil assembly rests on the core insert. Thermoplastic rubber is then injected into the mold cavity to completely encapsulate the transformer coil assembly in a jacket of thermoplastic rubber. During the injection step, gas in the mold cavity is vented through a vent space provided in the bottom surface of the mold cavity. A mold for encapsulating a transformer coil assembly in thermoplastic rubber includes a bottom mold portion having a mold cavity, an upstanding pin disposed within the mold cavity, a mold cover for closing the mold cavity, and a vent space positioned in the bottom surface of the mold cavity for venting gas within the mold cavity to the exterior of the mold during the injection of thermoplastic rubber into the mold cavity.
    • 封装的变压器包括变压器线圈组件,刚性芯插件,其具有位于芯的中空内部内的直立部分和芯部放置在其上的基部,以及完全围绕变压器线圈组件并结合的热塑性橡胶护套 到芯插入件的基部以提供完全防水的封装变压器,其对于可能对变压器的性能有害的液体和气体是不透水的。 一种用于制造这种封装变压器的方法包括将刚性芯插件放置在模具的模腔中,并将变压器线圈组件定位在模腔中,使得变压器线圈组件搁置在芯插入件上。 然后将热塑性橡胶注入模腔中,以将变压器线圈组件完全包封在热塑性橡胶的夹套中。 在注射步骤期间,模腔中的气体通过设置在模具腔的底表面中的通气空间排出。 用于将变压器线圈组件封装在热塑性橡胶中的模具包括具有模腔的底模部分,设置在模腔内的直立销,用于封闭模腔的模具盖,以及位于 模具腔,用于在将热塑性橡胶注入到模腔中期间将模腔内的气体排出到模具的外部。

    • A mass spectrometer having a mass filter which applies a transient voltage profile to accelerate ion packets. The voltage profile is chosen to have a functional form which imparts each ion species with a kinetic energy which is larger the larger the mass-to-charge ratio and a velocity which is smaller the larger the mass-to-charge ratio. The ions are detected in an ion detector which discriminates between different ion species based on their kinetic energy and taking account of the functional form of the voltage profile. Suitable voltage profiles include periodic functions such as sinusoids, triangles and sawtooths, which allow the amplification of drive pulses in the mass filter to be carried out with narrow band amplification stages, which are simple and inexpensive to construct.
