Abstract: A bottle for liquids is fitted with a dropper adaptor including a plastic body having extending longitudinally therethrough a flow channel. Over at least a first length portion thereof the flow channel has a cross section in the shape of a star with at least three branches. The channel opens outwardly from the body only at an outlet aperture at an outlet end of the flow channel and at an inlet aperture, defined by plural windows, at an internal end of the flow channel.

Abstract: Process for making transparent hollow bodies of terephthalate of polyethyleneglycol in which a preform is made, the preform is cooled rapidly to a temperature at least equal to the crystallization temperature, and is then rapidly expanded to obtain bi-orientation and solidification prior to substantial crystallization of the material. The preform can also be axially stretched during the operation. The apparatus for preforming the process includes a rotatable turret with mandrels, which operates to slightly expand the material on a mandrel.

Abstract: Hollow articles are made from a cylindrical preform by first elongating the preform to reduce its diameter and then blowing the elongated preform in a blow mold to produce the completed article, which is thus biaxially oriented.

Abstract: The invention relates to an apparatus for detecting the injection into an internal combustion engine, and in particular a diesel engine, comprising an injection pump, by means of an injector and at least one length of connecting tubing between the pump and the injector, this apparatus comprising means for detecting the transverse deformation of the connecting tubing under the pressure of the injected fuel.The detection means are disposed between gripper means for firmly locking the connecting tubing at two non-contiguous zones, and are carried by these gripper means in such a way that the sensitive parts of the detection means are applied, in the operative position of the apparatus, at least to the central part of the tubing between these two zones.
