Abstract: Blister pack panel for face powder compact display in which the purchaser checks the color of the face powder to determine the suitability of that color for the personal preferance of the purchaser by opening the compact, the blister pack being of a special novel construction to fit over the latching projection and around the hinge opposite the latching projection so that the blister retains the compact securely in tamper proof relation to the solid supporting panel used to display the case. Heretofore a pressure sensitive label which was dyed to match the color of the powder in the compact was affixed to the panel next to the printed description of the shade of the powder. These dyed pressure sensitive labels become soiled during handling by the purchasers and change color. Also the dyed labels may change color because of exposure to strong lighting as for example in a high intensity spot light which may be used for a cosmetic display case.

Abstract: A continuous rack support apparatus utilizing the gravity feed principle and in which goods to be stored are supported on rolling vehicles comprises thrust rods which are formed as motional impulse generators and arranged so as to be longitudinally displaceable in the center of a track. Pawls are associated with the thrust rods for acting upon the rolling vehicles. Each thrust rod has a locking member for holding it in a locked position following a displacement against the action of a spring. The locking member can be disengaged by the foremost rolling vehicle when the latter is removed. Along the thrust rods are wedges with which the pawls come into contact upon displacement of the thrust rods against the action of the spring to cause the wedges to swivel into a rest position below the track.

Abstract: In the process for the production of synthetic anhydrite and pure hydrofluoric acid, a reaction is initiated using fluorspar with a mixture containing sulphuric acid, oleum and the reflux of the acidic scrubbing. The aim is to produce synthetic anhydrite which contains only the desired small proportion of CaF.sub.2, while the free H.sub.2 SO.sub.4 is completely neutralized, but other desirable accelerators are still retained. The reaction is so arranged that fluorosulphonic acid does not enter the reactor at all or only in minute quantity and the new formation of fluorosulphonic acid is effectively repressed. For this end, the components of CaF.sub.2 and acid mixture are fed into the reactor at an elevated temperature and the reactor intake is so heated, whereby the reaction is initiated at 100.degree. C. and thus new formation of fluorosulphonic acid is arrested. The exhaust gases from the reactor are hot-dried in a first stage and the dust is expelled, before the material is cooled in the subsequent stages.
