Title: Distinguishing natural from synthetic diamond
Inventor: SPEAR PAUL MARTYN
IPC: G01N21/64
Filed: 1994-03-04
Abstract: Natural and synthetic diamond are distinguished by irradiating diamond 1 with ultraviolet radiation which is preponderantly of wavelength 225nm or less from source 5, such that substantially only the surface region of the diamond is irradiated. By observing with eg. a microscope 11 or camera 12 the pattern of luminescence and/or phosphorescence produced by the diamond 1, an observer can identify the diamond 1 as a natural or synthetic diamond. In an alternative cathodoluminescence method, a diamond can be placed in an electron beam and the pattern of luminescence and/or phosphorescence produced by the diamond observed in order to determine whether there is a layer of synthetic diamond deposited upon the diamond. <IMAGE>

Zirconium and hafnium are separated from a material containing them by dissolving the material in sulphuric acid of concentration between 0.1 and 0.4 M, contacting an anionexchange resin in the bisulphate form with the solution formed, developing the resin by displacement using a sulphuric acid solution of a zirconium salt and recovering the hafnium thus displaced, and regenerating the resin by elution with sulphuric acid, at least part of the zirconium free from hafnium being obtained in the eluant. The process is preferably effected in a continuous and countercurrent fashion using a movable mass of resin. The anion exchange resins are advantageously of the strong base type, e.g. those known under the Trade Marks "Dowex 2" " and " Amberlite IRA-410." Specifications 755,601 and 838,262 are referred to.

Abstract: An active matrix liquid crystal display 40 or 50 comprises an active matrix of control elements arranged in rows at the intersections of data lines 43 and scan lines 41 or and having data inputs connected to the data lines 43 and scan inputs connected to the scan lines 41. The display further comprises a data line driver circuit 44 or 55 for sampling the input signal to produce data signals for each of the rows of control elements in a corresponding line period, and a scan line driver circuit 42 for addressing the scan lines 41 sequentially by applying a scan signal to the scan inputs of the control elements along each of the rows so as to supply said data signals to the control elements along the row. Such circuits are controlled so that a data input signal is sampled and stored to produce data signals for a first group of the control elements along the row in a first line subperiod and the stored data signals are applied to the first group of control elements in a second line subperiod, and so that the data input signal is sampled and stored to produce data signals for a second group of control elements along the row in the second line subperiod and the stored data signals are applied to the second group of control elements in a subsequent line subperiod. Such an arrangement provides an efficient driving scheme which can be implemented without undue circuit complexity, and in particular which requires only a single data memory for each data line.

IPC: H05B3/14
Filed: 1997-12-10
Abstract: A self-limiting electric heater comprises a PTC element 1 in the form of a body having first and second faces 2,3 opposite one another and first and second ends 4,5 opposite one another, and a series resistance element 6 in form of a layer (preferably a coating) on the first face 2 so as to be in intimate thermal contact with it.
