Title: The Innovations of Donald W Tomkins
Introduction
Donald W Tomkins is a notable inventor based in Loughborough, GB. He has made significant contributions to the field of technology and materials science, holding a total of 2 patents. His work reflects a blend of creativity and technical expertise, particularly in the areas of positional detection and hydraulic cements.
Latest Patents
One of Tomkins' latest patents is a method of and apparatus for the positional detection of objects. This innovative holographic technique allows for the detection of the position of known items, enabling the rejection of samples that do not meet specific spatial parameters. The system utilizes a plate containing a single exposure of a three-dimensional holographic image, illuminated by parallel reference beams from a laser. This setup facilitates the reconstruction of a real focused image of the object. A displacement translator supports the object, allowing for movement in three orthogonal directions. The coincidence of the object and its holographic image can be detected optically or electrically using a stereoscopic microscope and a photo-diode.
Another significant patent by Tomkins involves modified hydraulic cements. This product comprises a hydraulic calcium silicate-based cement with specific characteristics, such as a Blain surface area of at least 3,000 cm²/g and an iron content of less than 2.5% by weight. The cement is treated with an additive that can enhance its properties, leading to modified morphologies and improved physical strength. These cements can be utilized in various applications, including the production of pre-cast units for the construction industry.
