The interior side has a part forming surface including a surface profile for forming a part. The exterior side has a plurality of hollow cores defined by longitudinal walls and lateral walls meeting at joints. Press inserts are coupled to the longitudinal walls and the lateral walls at the exterior side. The press inserts are configured to be pressed inward by a pressing load during a pressing operation for forming the part. The press inserts distribute the pressing load along the longitudinal and lateral walls.

Method and device for producing a bioartificial tissue construct

The tissue construct with viable cells in an extracellular matrix made of fibrin is produced with a special method, in which a matrix material and cells are shaped into a hollow body, in particular a tubular hollow body, by means of a rotational casting method in a hollow mould (1), the method comprising the following steps: (a) introduction of cells of at least one cell type and/or a fibrinogen preparation into the rotating hollow mould (1) with the aid of an applicator (4), said applicator (4) being displaced along the rotational axis during the introduction and step (a) being performed one or more times; (b) continuation of the rotation process until the fibrinogen solidifies into a dimensionally stable matrix, obtaining a primarily solidified tissue construct; (c) removal of the tissue construct from the mould. The construct can also he obtained in a relatively short time from autologous materials.

Solids in borehole fluids

Solid polymer objects have size at least 0.5 mm in each of three orthogonal dimensions and shape such that each object has one or more edges, points or corners and/or has a plurality of projections which extend out from a core portion. Such objects may be included in a drilling fluid as a lost circulation additive intended to bridge fractures and mitigate fluid loss. Their angular shape features make it harder for them to slide over fracture faces or each other and helps them to bridge a fracture. A method of making these objects provides a travelling endless belt made of elastomer and defining mould cavities. The mould cavities are filled with a polyerisable liquid composition, which is cured in the mould as the belt advances, and the cured objects are ejected from a mould as the belt bends around a roller.
