The present invention provides a system 10 for construction of formwork where a settable compound is pourable into a cavity in the formwork and retained by the formwork to set to form a completed structure. The formwork comprises structural panels 12, 14 connected by adjustable connectors 34 for varying the spacing between the panels.

A method is for manufacturing an ornamental part, for example a watch, jewellery or telephone part, in particular a watch crown. The part includes, at least partially, a hard material with a Vickers hardness exceeding 1,000 HV. The method includes the following main steps: producing a precursor from a mixture of at least one powder material with a binder, producing an insert made of a polymer material, the insert having, at least partially, a negative shape of that desired for at least one portion of the part, overmoulding the precursor onto the insert made of a polymer material by injection into a mould to form a green body, and sintering the green body to form a body of the future part from the hard material.

A modular pavement slab including a paving material set around a plurality of forming tools and defining a side face and a top surface. Each of the forming tools includes an elongate body extending along a longitudinal axis and having a sidewall exterior surface configured for removal of the elongate body through the side face. Each of the forming tools also includes a riser releasably coupled to the elongate body and extending in a direction noncollinear to the corresponding longitudinal axis.

A void former is arranged in a mold (30). The void former includes an insert (1) made of flexible material that forms a loop around a core region (15) within the mold. Casting material is added in a fluid state into the mold so as to fill a predefined volume for the facing element, including the core region. After hardening of the casting material, the facing element (10) is removed from the mold, and the void former is removed from the facing element. The facing element comprises an anchoring core formed by the hardened casting material in the core region (15). Removing the void former comprises pulling the insert (1) away from a rear surface of the facing element (10). The flexible material of the at least one insert is deformed around the anchoring core (15) while it is pulled.

An arthroscopic or other surgical cutter has features which facilitate fabrication by ceramic molding. The arthroscopic cutter includes a cutter body having a longitudinal axis and a window, an interior channel, and a plurality of cutting edges extending radially outwardly from an outer surface thereof. The features include non-helical, longitudinally aligned cutting edges, controlled thicknesses of the cutting edges, controlled heights of the cutting edges, controlled areas of the windows, controlled diameters of the internal channels, controlled rake angles of the cutting edges, and other parameters.

A method and apparatus for forming a part having a cavity with a complex contour is presented. The molding apparatus comprises a mold cavity and a molding insert. The mold cavity is formed by a first mold portion and a second mold portion. The molding insert is within the mold cavity, wherein the molding insert has a forming surface, and wherein the molding insert is configured to move in more than one direction relative to the first mold portion.

A pocket former may include a pocket former body, the pocket former body having an outer surface. The pocket former may further include a collapsible element, the collapsible element formed on the outer surface of the pocket former body. The collapsible element may extend radially outwardly from the pocket former body.

The present invention provides a system 10 for construction of formwork where a settable compound is pourable into a cavity in the formwork and retained by the formwork to set to form a completed structure. The formwork comprises structural panels 12, 14 connected by adjustable connectors 34 for varying the spacing between the panels.
