Abstract: A measuring circuit for the additive phase noise characteristic of a component in the vicinity of a carrier frequency. The measuring circuit is constructed of a central channel and two side channels. Each of these channels contains a model of the component to be characterized. Two phase detecting circuits are employed in which each processes an input signal from one of the side channels with an input signal from the central channel to generate signals which represent phase deviations between the two input signals. An intercorrelation circuit then utilizes the outputs from these phase detecting circuits to determine the characteristic additive phase noise of the component to be characterized by eliminating any additive phase noise superadded by other measuring circuit elements or induced by outside disturbances.

Abstract: A packaging pot for marketing various products, comprising a container housed within a casing body covered by a casing lid which pivots about a horizontal articulation, with a resilient snap-action closure system releasable by manual action on an externally projecting lug. The container is clamped in a single-piece ring comprising a lower annular member which is integral with the container and a pivoting upper annular member which is joined to the lower annular member by means of a flexible hinge-strap, the two annular members being provided respectively with complementary snap-fastening elements, the top portion of the casing body being fastened around the lower annular member and the bottom portion of the casing lid being fastened around the upper annular member.
