    摘要: This invention relates to an improved amorphous zirconium hydroxide and a method for its production. The hydroxide has a surface area of at least 300 m2/g, a total pore volume of at least 0.70 cm3/g and an average pore size of between 5 nm and 15 nm, and is prepared by a process which comprises the steps of: a) preparing an aqueous solution comprising sulphate anions and a zirconium salt such that the ZrO2:SO3 ratio is 1:0.40 to 1:0.52, (b) chilling the solution to below 25° C., (c) adding an alkali in order to precipitate the amorphous zirconium hydroxide, (d) filtering and washing the precipitated zirconium hydroxide with water or an alkali to remove residual sulphate and chloride, (e) hydrothermally treating the zirconium hydroxide at a pressure of less than 3 barg, and (f) drying the zirconium hydroxide. The zirconium hydroxide of the present invention, which can be doped, is particularly useful in catalytic applications.

    摘要: A probe for position-determining apparatus and the like having a housing and in the housing a sensing space and an aperture to the sensing space, a stylus extending out of the sensing space through the aperture, and a stylus-support at the aperture. The stylus is constrained in low-friction engagement with the stylus support towards a generally neutral axis while permitting position-determining displacement on the stylus support. The stylus is linked to the constraining low friction engagement through a lever arrangement including a first lever element extending sideways from and around the stylus and a second lever from the first lever to transfer stylus displacement to the constraining low friction engagement. The lever arrangement includes an abutment engageable by the second lever.

    摘要: A probe for a position determining apparatus includes a sensing space and a movable stylus supported for three-dimensional position determining movement which extends into the space. A device emits sensing radiation into the space and a collector collects the sensing radiation from the space. A deflector is supported on the stylus within the space to deflect emitted sensing radiation and is movable with position determining movement of the stylus. The deflector concentrates the sensing radiation and the collector is sensitive to variations in the intensity distribution of collected deflected radiation which occur due to the three-dimensional movement of the stylus.

In one embodiment (FIG. 1) the probe incorporates a bundle of, say, seven optical fibers which each have one end exposed at an end plane of the bundle and constituting a respective one the light-collecting elements, the fibers being connected at their other ends to photodiodes or other photodetector means for measuring the Incidence of light on the exposed ends of the fibers. In another embodiment, the light-collecting elements are the individual detector cells comprised in the detector array of a solid state camera, the cells being organized in groups each having a central cell and a plurality of surrounding cells, and the illuminating means may be a screen with appropriately located apertures illuminated from behind.
