Abstract: Integrated structures of various combinations of inductors, capacitors and resistors are formed by bonded laminations of films of electrical conductors of desired configurations and electrical properties separated by films of dielectric material. Electrical terminals extending from appropriate ones of the conductors may be interconnected selectively to provide various single, series and parallel circuit component arrangements.

Abstract: A method and apparatus for determining the low temperature characteristics of materials measures the resistivity of a sample material and the resistivity of a comparision material and plots the ratio of the resistivity of the comparision material to the resistivity of the sample material versus the temperature of the sample material. In addition, the method and apparatus measures the temperature of the sample and the temperature of a reference material and plots the difference there between as a function of the temperature of the reference material. The method and apparatus is usable in monitoring and/or controlling lyophilization appartus in order to increase the efficiency of the freeze drying process, that is, increasing product yield while reducing processing time.

Abstract: Technique and apparatus for measuring liquids and granular material comprises a combination including a measuring vessel attached adjacent to the top and communicating with the primary container through the modifying pour spout of the latter. The measuring vessel includes an outwardly directed dispensing mouth having a removable closure, and a second upwardly directed opening vertically aligned with the pour spout of the primary vessel. In a preferred embodiment, the modifying pour spout of the primary container serves as a handle for the combination. After the primary container is filled through a tube extended through the second opening of the measuring vessel, this opening is either sealed, or a manually-operable valve is interposed into the opening. The manually-operable valve may alternatively take the form of a flap valve, or a piston valve, either of which operates to open and close communication through the modifying pour spout between the measuring vessel and the primary container.

Abstract: A technique and apparatus for measuring liquids and granular materials comprising a measuring head which may either take the form of an attachment to or an integral part of a conventional primary container. The measuring head comprises two elements: (1) an upwardly extended modifying pour spout seated on the mouth of the primary container and disposed at an acute clockwise angle to the axis of the primary container; and (2) a measuring vessel which encloses or is coupled to the modifying pour spout of the primary container, and which has its own dispensing mouth disposed at a counterclockwise angle relative to the axis of the primary container. The pour angle of the primary container is so modified relative to the dispensing mouth of the measuring vessel that the filled contents of the measuring vessel can be completely dispensed without any of the contents of the primary container escaping into the measuring vessel.

Abstract: An electrical inductance coil, having a central opening therethrough, is surrounded by a spaced shield of magnetic metal, and a screw of magnetic metal is mounted in engagement with one side of the shield for adjustable extension through the central opening in the coil for varying the spacing between the inner end of the screw and the confronting, opposite side of the shield.
