Disclosed is a method implemented by computer for determining a lens blank intended to be used for the manufacturing of a finished optical article. The method includes: —a virtual volume data determining step, during which virtual volume data are determined based at least on finished optical article data representative of the volume of the finished optical article and over-thickness data representative of over-thickness requirements, the virtual volume data are determined so that the virtual volume defined by the virtual volume data includes the volume of the finished optical article volume of the finished optical article and the over-thickness, —a lens blank determining step, during which a lens blank is determined based on the virtual volume data so as to include the virtual volume defined by the virtual volume data.

Three-dimensional decorative articles are produced from blanks of heat-shrinkable plastic sheet material, using a mold base having an outer surface with a recess over which a blank is placed, and a convex mold insert that moves into the recess by gravity as the blank softens and cooperates with the interior wall of the recess to shape the sheet material into a three-dimensional decorative article. A guide peg extends outward from the bottom of the recess past the outer surface of the mold base and extends through a hole formed in the blank, and through a guide hole in the mold insert to support the mold insert before heating and to guide the mold insert as it moves into the recess of the mold base.

A method of manufacturing a midsole includes placing first and second preforms into a midsole recess of a mold, with first and second portions of the mold defining a first overflow chamber connected to the first recess; closing the mold by positioning the first and second portions in contact with one another; heating the mold for a predetermined period of time at a predetermined temperature such that the first and second preforms melt and bond together to form a midsole, with a portion of each of the first and second preforms flowing into the first overflow chamber to form a first overflow portion; removing the midsole from the mold; allowing the midsole to expand; and cutting away the first overflow portion.

The invention relates to a method for producing a tubular hollow body (1) with at least three pipe openings, partly or completely consisting of plastics material. It is provided that a lost core pipe (9), which has a connection opening (13, 14) on each of its ends and has at least one docking opening (11) along its length, is produced, that the core pipe (9) is introduced into a cavity of a mold, with two non-lost core pieces (17, 18) being arranged with one of their ends (3, 4) respectively against the connection openings (13, 14) in a sealing manner and a non-lost core part (19) being arranged with one end against the docking opening (11) in a sealing manner, in that plastics material (25) is then introduced into the mold cavity to encapsulate the core pipe (9), the core pieces (17, 18) and the core part (19) and that, once the plastics material (25) has cured, the core pieces (17, 18) and the core part (19) are withdrawn from the hollow body (1) created. The invention also relates to a corresponding hollow body (1).

An assembly for densification under load along at least one direction of compression. The assembly includes: at least one volume to be densified having a powdery and/or porous composition and having variations in thickness along the direction of compression; and at least one counter-form of a powdery and/or porous composition, having at least one face facing at least one portion of the volume. The face and each of the portions are separated by at least one deformable interface layer.

A tape dispenser system includes a monolithic plastic injection molded frame with an integral anti-reverse rotation pawl. To help prevent the free end of a roll of tape from accidentally retracting, falling back, and frustratingly bonding onto the coiled portion of the tape, the pawl engages the inner diameter of a cardboard spool that holds the roll of tape. Strategically located mold parting lines and certain air gaps allow injection molding of a dispenser frame that has two spool-supporting sidewalls plus the integral pawl.

A contact lens mold part and a contact lens mold assembly (1) are provided. The contact lens mold assembly includes a first mold part (2) and a second mold part (3) assembled together. Each mold part has a lens-forming surface with a circumferential edge, a stop surface extending from the circumferential edge, an intermediate region extending from the stop surface, and an alignment surface extending from the intermediate region. The mold parts can be made to fit together with an interference fit. A method of making a contact lens using the contact lens mold assembly is also provided.

A tire vulcanizer is disclosed that has superior durability and in which mold parting surfaces defined by a sector and side plates are less likely to be worn even after repeated use. The tire vulcanizer includes: the sector that shapes a tread of a tire; paired upper and lower side plates that shape sidewalls of the tire; a segment that is fixed to the sector and causes the sector to move in a tire radial direction; paired upper and lower attachment plates that are respectively fixed to the paired upper and lower side plates; and the mold parting surfaces defined by the sector and the side plates. Mold inner ends of the mold parting surfaces are arranged on the tread, and the mold parting surfaces extend outward in the tire radial direction from the mold inner ends.

A closure (1) for sealingly closing a container neck (11) having a tubular body (2) with a top wall (4), an annular side wall (5), an intermediate wall (6) joining the side wall (5) to the top wall (4) and an annular tamper evidence band (3) frangibly connected to an open end (21) described by the side wall (5). The band (3) includes retaining cams (31) protruding from its inner surface (30). Each cam (31) has a lead-in ramp (32) for engaging, in use, the flange (12) of a container neck (11) as the neck (11) is introduced into the open end (21) of the body (2) and a stop (33) for engaging the flange (12) to separate the band (3) from the body (2) when the closure (1) is subsequently removed from the neck (11). Each lead-in ramp (32) has a central recess (34) therein.

The disclosed embodiments relate to a lacrosse head and a method of manufacture to form the same. A lacrosse head may include a scoop, a throat, and a pair of opposed sidewalls configured to interconnect the scoop to the throat, each sidewall having an interior edge and an exterior edge. The lacrosse head may further include a hub connected to the throat, the hub including a socket configured to receive a stick. Additionally, at least one of the scoop, throat, pair of opposed sidewalls, and hub comprise a matrix material embedded with a plurality of substantially randomly dispersed reinforcing fibers. A method of forming a lacrosse head may include forming a mold assembly having a positive side and a negative side, mixing a composite matrix material by feeding chopped reinforcing fibers randomly into a resinous material, setting the matrix material into the mold assembly, and closing the mold assembly.
