A method of forming a retaining device with hooks, wherein: a molding strip is provided that presents an inside face and an outside face, and that has a plurality of cavities, each cavity defining a stem extending from the outside face towards the inside face and including an end forming a head that extends from the stem towards the inside face of the molding strip; the molding strip is positioned on rotary drive means, the inside face of the molding strip being arranged to bear against the drive means; and molding material is dispensed against the outside face of the molding strip.

A method of and fixture for molding a product with an embedded ring. A system for molding a ring into a product including a rotational molding mold with an opening formed in the rotational molding mold sized to fit a ring. A fixture is removably couplable to the ring, wherein the ring and the fixture when coupled are removably couplable in the opening. The fixture is removed from the ring after the ring is molded into a product. A method of manufacturing a product with an embedded ring includes: coupling a ring to a fixture; clamping the fixture and the ring in an opening in a mold top; clamping the mold top to a mold bottom; rotomolding a product; unclamping the fixture from the mold top; uncoupling the fixture from the ring; unclamping the mold top and the mold bottom; and removing the product from the mold.

This relates a lifter bar, method for making a lifter bar, a method for assembling a lifter bar and a grinding mill for ore grinding. The lifter bar comprises a lifter bar body having an outer surface conforming the outer surface of the lifter bar, and a fixing element for connecting the lifter bar to the shell of the grinding mill. The lifter bar body further comprises a first portion and a second portion forming a continuous lifter bar body. The fixing element is embedded to the first portion such that it forms part of the fixing surface of the lifter bar. The second portion is made of polyurethane and forming 35-85% of the volume of the lifter bar.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

A device for pastillating a flowable product, in particular a melt. The device has a revolving belt and a drop former, and the drop former deposits product drops on an upper run of the belt. The product drops, in the course of transportation on the upper run of the belt, solidify to form pastilles, and an arrangement for wetting the belt with a liquid release agent is provided upstream of that region in which the product drops are deposited on the belt. The release agent prevents or reduces the adhesion of the product drops to the belt, and a proportional metering pump is provided for continuously mixing the release agent from at least two liquid components during the operation of the device.
