Abstract: A contact lens includes at least two focal lengths, a single lower bearing surface capable of allowing the lens to be translated relative to an eye, and an area placed in the lower portion of the lens, the area having an outer face connected to a remainder of the outer face of the lens via a recess and the area having an inner face indistinguishable from the rest of an inner face of the lens, where the recess defines the lower bearing surface, and where the area is thin with an average thickness of the same order of magnitude as a thickness of an upper edge of said lens.

Abstract: A threadless cap for closing a potable liquid bottle is provided. The potable liquid bottle has a neck with an upper edge defining a discharge opening. The threadless cap comprises a lid for overlying and sealingly engaging the upper edge of the neck. The lid includes a tension ring for retaining the cap on the neck of the bottle, the tension ring having an inwardly extending rib for engaging the neck of the bottle. The threadless cap also comprises a skirt depending from the lid, the skirt including a line of weakness facilitating a manual tear of the skirt. The threadless cap further comprises a tear stop at a location intersecting a line of tear propagating as a result of a manual pull applied on the skirt, the tear stop preventing the line of tear to propagate beyond the tear stop.

Abstract: A threadless cap for closing a liquid bottle, the liquid bottle having a neck with an upper edge defining a discharge opening. The threadless cap comprises a lid for overlying the upper edge, the lid including a surface for facing the upper edge and a projection extending from the surface toward the upper edge. The threadless cap also comprises a skirt depending from the lid. The threadless cap further comprises a seal member on the surface for establishing a sealing engagement with the upper edge. The seal member includes an arcuate bead of resilient material located on the surface in a position to register with at least a portion of the upper edge. The projection engages and extends along the arcuate bead of resilient material. A blank for such a threadless cap and a method for manufacturing such a threadless cap are also provided.

Abstract: The invention relates to a stopper, provided with an obstructor (1), for a can. Said stopper comprises a cap (3) provided with a central opening (5) and an annular skirt (7), and an annular shaft (17) extending around the opening, in addition to a capsule (19) which is detachably fixed, by means of a tear element (23), to a free edge (25) of the shaft opposite the opening. The tear element joining the shaft to the capsule is placed in an entrance area at an angle in the free edge of the shaft. At least one sealing lip (37) is disposed on the inner surface of the shaft, and the cap, skirt and capsule of the stopper are moulded in a single piece without any welding or the addition of another component or detachable part. The invention also relates to a method for the production of said stopper by offset injection in a region which is outside the cap.

Abstract: A continuous casting installation for metals comprises a submerged nozzle surrounded by an annular electromagnet inductor with a magnetic field that rotates around the casting axis, and which drives the molten metal in an axial rotation. The inductor is a polyphase type with a magnetic field passing therethrough and is equipped with a pair of projecting poles (3) per phase. The end of each projecting pole opposite the nozzle is provided with a lateral narrowing which increases the distance separating the polar ends.

Abstract: A method of manufacturing a hollow shaft having internal swellings of revolution is disclosed. Hollow shaft sections, each having at least one internal swelling of revolution, are consecutively formed in a substantially continuous cold extrusion process using a single punch 7. Tubular blank 1a is extruded through narrowed orifice 14 of die 8. Tip 10 of punch 7 is inserted into axial passage 11 of blank 1a and shoulder 13 of punch 7 engages a rear end of blank 1a to push blank 1a partially through narrowed orifice 14 and thereby compress the front end of blank 1a between tip 10 and narrowed orifice 14. Punch 7 is then removed from die 8 and another tubular blank 12 is introduced in die 8 with its front end in abutment with the rear end of deformed blank 1b.
