A method of filling a mould with a settable material, such as a cementitious mixture, is disclosed. The mould includes a plurality of cavities that open to a top face of the mould, and is suitable for forming building elements, such as pavers, for covering surfaces. The method includes providing an additional volume per unit area of settable material to at least part of selected ones of the cavities, and compacting the settable material in at least part of all of the cavities, including the additional volume per unit area of settable material provided to the selected ones of the cavities, to substantially the same thickness. A mould and a scraper suitable for use in the method are also disclosed.

A technique for allowing the convenient and orderly withdrawal of contents is disclosed. An apparatus according to the technique may include a container which includes an enhancement at the rim of the container. The enhancement provides the functionality to move edible and/or inedible substances onto objects. In one example, the enhancement may protrude inwardly as a smoothed surface that may push substances onto objects as the objects are removed from the container.

A method of supplying a made-to-order flood source includes, in response to receiving an order for a flood source from a customer, selecting a mold from a plurality of molds to meet a size of the flood source ordered. A radionuclide is dispersed in a heat curable matrix material to form a mixture. The mixture is cured in the selected mold by application of heat. The cured mixture may be thereafter removed from the mold and encapsulated to form the flood source. The method allows the finished flood source to be shipped to the customer within twenty-four hours of receiving the order.

An adjustable baking form includes a strip of malleable material forming a series of longitudinally extending discrete links. Each link includes a wall section and a base section extending transversely from the wall section. The base sections are bent generally perpendicularly to the respective wall sections and the wall sections are bent relative to one another to hand-manipulate the strip into a desired shape. When opposite ends of the strip are brought together, the links cooperatively form a baking vessel. Baking a cake includes providing a roll forming a series of discrete links and manipulating the roll to a desired shape. The first and second ends of the roll are joined to form the baking vessel having the desired shape. A resultant cake is obtained in the shape of the baking vessel after placing the baking vessel on a baking pan and pouring batter into the baking vessel.

A tool for making a mounting or holder for a tablet-shaped sample which is to undergo analysis in an analytical instrument, the tool comprising a moulding which defines a lower surface and a side wall or walls, and a pin which, in use, extends upwardly above the lower surface of the moulding. The arrangement being such that in use a tablet is mounted on the upper end of the pin and mouldable material is introduced into the moulding so that it locates around the lower part of the tablet.

A process for producing a methacrylic resin molded article having a surface fine structure with a high aspect ratio. The method includes injecting a composition into a cell or cavity provided with a negative pattern corresponding to the surface fine structure, and solidifying the composition in the cell or cavity by polymerization. The composition contains components A, B, and C. A: an unsaturated monomer mixture, which includes 20 to 90% by weight of an unsaturated monomer including methylmethacrylate as a major component, and 10 to 80% by weight of an unsaturated monomer having at least two polymerizable double bonds in one molecule; B: a polymer of an unsaturated monomer including methylmethacrylate as a major component, which polymer includes 20 to 100% by weight of partially crosslinked polymer particles and 0 to 80% by weight of non-crosslinked polymer particles; and C: a polymerization initiator.
摘要:
In a method of manufacturing a resin molded article, resin including a foaming agent is injected into a cavity defined in a mold assembly. Then, a movable mold of the mold assembly is moved to partly expand the cavity so that the foaming is promoted at the part where the cavity is expanded. Therefore, a high foamed portion having voids therein and a low foamed portion having an expansion ratio less than that of the high foamed portion are integrally formed in the resin molded article.

A method is disclosed of making a mounting or holder for use in analysis in an analytical instrument of samples of similar shape. The method includes obtaining a moulding that includes a protrusion; securing a sample having a lower surface and a side surface to the top of the protrusion of the moulding; introducing a mouldable material into the moulding only up to a level that is along the side surface of the sample and above the lower surface of the sample; allowing the mouldable material to set to form a mounting or holder; and separating the mounting or holder from the sample and the moulding.
