20110166823 | SURFACE MEASUREMENT INSTRUMENT - A surface measurement instrument for obtaining surface characteristic data of a sample surface is described. Relative movement between a reference surface and a sample support is caused to occur while a sensor senses light intensity at intervals along a scan path to provide a series of intensity values representing interference fringes produced by a region of a sample surface during said relative movement and from which series of intensity values surface characteristic data can be derived. The sample support is both translatable and tiltable in at least one direction perpendicular to a scan direction so that the sample support can be both tilted to cause the scan path to be normal to the sample surface region and translated to compensate for translation movement due to the tilting. | 07-07-2011 |
20120004888 | APPARATUS FOR AND A METHOD OF DETERMINING SURFACE CHARACTERISTICS - A coherence scanning interferometer carries out: a coherence scanning measurement operation on a surface area using a low numeric aperture objective so that the pitch of the surface structure elements is less that the spread of the point spread function at the surface to obtain structure surface intensity data; and a coherence scanning measurement operation on a non-structure surface area to obtain non-structure surface intensity data. A frequency transform ratio determiner determines a frequency transform ratio related to the ratio between the structure surface intensity data and the non-structure surface intensity data. A structure provider sets that frequency transform ratio equal to an expression representing the electric field at the image plane of the interferometer in terms of surface structure element size (height or depth) and width-to-pitch ratio and derives the surface structure element size and width-to-pitch ratio using the frequency transform ratio. | 01-05-2012 |
20120176624 | APPARATUS FOR AND A METHOD OF DETERMINING SURFACE CHARACTERISTICS - Light reflected by a sample surface region and a reference surface interfere. A detector senses light intensity at intervals during relative movement along a scan path between the sample surface and the reference surface to provide a series of intensity values representing interference fringes. A data processor receives first intensity data comprising a first series of intensity values resulting from a measurement operation on a surface area of a substrate and second intensity data comprising a second series of intensity values resulting from a measurement operation on a surface area of a thin film structure. A gain is determined for each thin film of the thin film structure. Substrate and apparent thin film structure surface characteristics are determined on the basis of the first and second intensity data, respectively. The apparent thin film structure surface characteristic is modified using the substrate surface characteristic and the determined gain or gains. | 07-12-2012 |

20150025845 | SURFACE MEASUREMENT APPARATUS AND METHOD - A stylus is deflected as a tip of the stylus follows surface variations along a measurement path on a surface of a workpiece. A transducer provides measurement data in a measurement coordinate system. A data processor is configured to: determine a relationship between the data in the measurement coordinate system and nominal surface data representing the expected surface characteristic of the workpiece in a workpiece coordinate system; simulate a measurement data set for the nominal surface using the nominal surface data and the determined relationship; if a simulated range of the simulated data set does not meet a given criterion, adjust a selected measurement data value for a selected point and repeat the simulation to determine an adjusted data value for which the simulated range meets the criterion; and determine start conditions required for a measurement procedure to provide the adjusted data value for the selected measurement point. | 01-22-2015 |

20090029837 | STITCH FLAP CUTTING BLOCK - A stitch flap cutting block is mountable to a cutting head of a board blank cutting machine, along with a slotting knife. A sheet of board passed between the cutting head and an anvil head is cut to form a blank for a box or the like. The cutting block comprises a steel body with a cylindrical barrel holding a cylindrical spring block, to which is mounted a blade holder carrying an elongate blade. The blade moves within a transverse slot across the body and is deflectable into the body and may rock about a midpoint of the slot. Impact forces are reduced, cleaner cuts are produced, and re-setting of the blade is required much less often. An alternative stitch flap cutting block is mountable to the cutting head by a separate side arm, facilitating mounting cutting to heads having different diameters. | 01-29-2009 |

20150161921 | DISPLAY UNIT - A display unit comprises a display stand—preferably of cardboard—having at least one marking (t/g) comprised of a material that fluoresces when irradiated with ultra-violet light, and an electrically operated source of ultra-violet light for irradiating said marking (t/g). The marking (t/g) may be on a surface of an open-fronted compartment of the unit and the ultra-violet light source may be partially shielded from extraneous light by a frontal lip of compartment. The unit may further comprise a box-like construction with a face having cut-outs defining stylised lettering. Behind the face is a fluorescent material visible through the cut-outs and at least one source of ultra-violet light, operation of which gives the appearance of the stylised letters being at the front of, and illuminated by, a lit chamber. | 06-11-2015 |

20090289620 | Clearance determination device - A device is provided for measuring the clearance between a member and a surface over and relative to which the member moves. The device has a first reference element, and a second reference element which faces the first reference element, and is movable to alter the distance to the first reference element. The device further has a fastening system for fastening the device to the member so that, during the relative motion, the first reference element is held in a fixed position relative to the member and the second reference element slides over the surface. The device further has an urging arrangement which urges the second reference element into contact with the surface so that, as the second reference element slides over the surface and the clearance between the member and the surface varies, the second reference element moves relative to the first reference element. The device further has a sensor which measures the distance between the first and second reference elements. | 11-26-2009 |
