摘要:
A method of selectively combining particulate material, for example plastics material by sintering, comprises providing a layer of particulate material, providing radiation, for example using a radiation source over the layer, and varying the absorption of the provided radiation across a selected surface portion of the layer to combine a portion of the material of the layer. The method may comprise varying radiation absorption by varying the intensity of the radiation incident on the surface portion of the layer, or alternatively may comprise varying the radiation absorptive properties of the particulate material over the selected surface portion of the layer, for example by printing a radiation absorbent material onto the surface portion.

A method of verifying the integrity of a seal in a sealing region between a container and a sealing film applied to the container comprises viewing at least the sealing region to detect the presence of a detectable predetermined feature in the sealing region. The presence of the detectable predetermined feature in the sealing region is indicative of an improper seal between the container and the sealing film whilst the absence of the detectable predetermined feature in the sealing region is indicative of an integral seal between the container and the sealing film.
摘要:
The present invention provides a method of automatically translating modeling language code to hardware language code and a code translator. The modeling language code is parsed to extract values associated with predetermined ones of a plurality of constructs to generate parsed modeling language code; and a transformation block is applied to the parsed modeling language code. The transformation block is adapted to convert the parsed modeling language code into hardware language code.

An inorganic pigment, the pigment comprising a compound which is an oxysulphide or oxyselenide of tin and a metal chosen from niobium or tantalum. The pigments are brightly colored in the color range from yellow, through orange to red, and are especially suitable for the coloration of glass and plastic substrates. Methods for the production of the pigments are also described.

A method of automatically translating modelling language code to hardware language code including: parsing the modelling language code to extract values associated with predetermined ones of a plurality of constructs; and populating, in a predetermined manner using the extracted values, empty fields of one or more predetermined templates wherein the or each template comprises code of the hardware language.
