An integrated process for the manufacture of HFO trans-1,3,3,3-tetrafluoropropene by first catalytically dehydrofluorinating 1,1,1,3,3-pentafluoropropane to thereby produce a mixture of cis-1,3,3,3-tetrafluoropropene, trans-1,3,3,3-tetrafluoropropene and hydrogen fluoride. The air is heated to a temperature of 250\xb0 C. In other types of apparatus, SMA shock-absorbing components are mounted in a frame so that the way in which the shock-absorbing component is deformed is independent of the direction of the shock received by the frame. In the housing and in the slide unit, at least one additional inner part is arranged in each case, each additional inner part enclosing the spout sleeve or the inlet sleeve. Thus obtained is a diffuser panel for a rear projection screen capable of contributing to improved clarity of images. Neurological or cognitive conditions are treated by administering to a subject an effective amount of a therapeutic compound comprising a nitrate ester, or a pharmaceutically acceptable salt or ester thereof.
