    摘要： Titanates of zinc and/or alkaline earth metals are produced by simultaneously adding to a suspension of finely divided TiO.sub.2, maintained at a substantially constant pH above about 8, a solution of a salt of zinc and/or alkaline earth metal and alkali to form a hydroxide precipitate. Filtration produces a filter cake mixture of TiO.sub.2 and hydroxide and calcination at above 500.degree. C. produces the desired titanate of narrow particle size distribution and desirable optical properties. Non-simultaneous addition results in a non-filterable material. Zinc, magnesium and/or calcium are preferred and doping elements such as aluminum, phosphorus, boron and/or silicon may also be present.

    摘要： A thermal fuse includes a leaf spring formed of a narrow sheet metal strip. The leaf spring has ends and at least two contact points at the ends. At least one of the contact points is a soldering point for connection with corresponding circuit contacts of a circuit substrate. The leaf spring has at least one spring arm interconnecting the contact points. The spring arm has a roof-shaped deformation in the vicinity of one contact point. The spring arm has a flat and elongated spring segment with a transition adjoining the deformation and a transition extending to the other contact point. The spring segment is bending resistant in the vicinities of the transitions, for transforming a compressive deformation applied to the roof-shaped deformation into a lateral movement and into an arching of the spring segment, with both ends of the leaf spring attached to the circuit substrate without pretensioning. A method for activation of the thermal fuse includes placing the contact points of the leaf springs free of tension on the circuit contacts, soldering the contact points to the circuit contacts, and compressively deforming the roof-shaped deformation after the soldering for creating an arching of the spring segment and a desired pretensioning.

    摘要： A method for the production of a radiographic screen comprising the following steps:1) dispersing phosphor particles in an organic liquid in the presence of a charge controlling agent that charges said phosphor particles with a positive or negative net charge,2) arranging said dispersion between a pair of electrodes, wherein one of said electrodes is or carries a conductive support of said radiographic screen,3) applying and maintaining between said electrodes a sufficiently high direct current voltage to deposit charged phosphor particles onto said conductive support, and4) separating said support carrying electrophoretically deposited phosphor particles from said organic liquid,wherein the dispersing of said phosphor particles proceeds by means of an organic surface active compound acting as dispersing agent for said phosphor particles, and said phosphor particles are electrostatically charged through adsorption thereon of ionic components of said organic surface active compound and/or through adsorption of cations or anions stemming from an ionic inorganic compound incorporated in said liquid.
