Abstract: A method of producing a container with a desired opening profile. The process of blow molding is used to produce a bottle (10). The bottle (10) has one or more integral dimple (13), posts (15), or hole features, which are in radial alignment. These features may be produced in the molding process or produced in a separate operation once the bottle has been ejected from the mold press. The neck (12) is then trimmed away and the desired opening profile is created. A second part, a door (14), may then be snapped onto the container's radial features to form a hinge (16).

Abstract: The present invention relates to a clock recovery circuit for generation of a recovered clock signal from a received data stream using a weighted combination of phase component signals. The clock recovery circuit comprises: a detector to detect the phase of a received data stream; a selector comprising a differential generator arranged to generate at least two related signals in dependence on the detected phase; and a clock signal generator to receive the at least two related signals and select related proportions of two or more of a plurality of phase component signals for combination, thereby to generate a recovered clock signal.
