| 20090026184 | Method and Apparatus for Scale Manufacture Without Substantial Removal of Material - A method of making metrological scale for scale reading apparatus includes directing a laser beam onto a scale substrate ( | 01-29-2009 |
| 20090032506 | Method of Scale Manufacture - The present invention relates to an apparatus for the manufacture of a metrological scale comprises a scale substrate ( | 02-05-2009 |
| 20090127131 | Scale Making Method - Apparatus and method for making a metrological scale by electrochemical machining of a scale substrate using a tool having at least one feature. The method has the steps of passing an electrolyte solution between the tool and the scale substrate and forming an electrical connection between the scale substrate and the tool. Electrochemical dissolution of the scale substrate occurs adjacent to the feature of the tool to produce at least one scale marking. This is suitable for making linear, rotary and two dimensional scales. | 05-21-2009 |
| 20100223778 | METROLOGICAL SCALE AND METHOD OF MANUFACTURE - A metrological scale for scale reading apparatus is described, along with a method of manufacture of said metro-logical scale. The scale comprises a fibre reinforced substrate, such as a carbon fibre composite, and a layer of material, such as a plated or stuck on layer of metal, into or onto which scale markings are made. The method of manufacture of said metrological scale comprises the steps of: making a scale body comprising a layer of material, and a fibre reinforced composite substrate, wherein the qualities of the substrate are tailored to achieve the required coefficient of thermal expansion; and, making graduations in or on the layer of material of the scale body to form a scale. | 09-09-2010 |
| 20110162223 | SCALE TRACK - A metrological scale track comprising at least first and second metrological scale track strips. The at least first and second metrological scale track strips are held in a spaced apart relationship by at least one spacer. The at least one spacer is configured to be removed once the at least first and second metrological scale track strips have been secured to a substrate. | 07-07-2011 |
