    摘要: An apparatus for producing an electrophotographic print on a photo-sensitive sheet (2) movable through a plurality of predetermined stations so as to produce an electrostatic latent image on the photosensitive sheet, the apparatus including a rotary drum (I) having a peripheral surface defining an image forming section (E) and a non-image forming section (F), the photosensitive sheet being placeable on the image forming section of the drum surface; a developing unit (3) having at least one developing section (30) for supplying a developer to the photosensitive sheet on the drum, thereby making the electrostatic latent image visible; and means (18) for collecting the used developer from the photosensitive sheet, the means being provided axially of the drum in the non-image forming section of the peripheral surface.

    摘要: A process for producing 2,4-dichlorobenzotrifluoride, which comprises reacting m-dichlorobenzene with a halogenated methane of the formula CF x Cl 4-x where x is 0, 1 or 2, and hydrogen fluoride at a temperature of from 80 to 180°C in the presence of a catalyst of at least one member selected from the group consisting of fluorides of antimony, boron, titanium, tantalum and niobium.
