Title: Bleaching of montan wax - by continuous mixing with chromic acid and distn. of water
Inventor: STETTER KARL-HEINZ DIPL CHEM D
IPC: C10G73/38
Filed: 1979-04-19
Abstract: Continuous bleaching of montan wax (opt. mixed with other waxes) is carried out by (a) mixing the molten wax with a chromic acid soln. contg. 60-140 g/l CrO3, 400-600 g/l total H2SO4 and 300-500 g/l free H2SO4 at elevated temp., and (b) agitating the mixt. while distilling off H2O in an amt. such that the free H2SO4 content remains >=200 g/l. The process is carried out in one or more stages using a total amt. of chromic acid corresp. to 50-250 pts. wt. CrO3 per 100 pts. wt. wax. In the 1-stage process, the wax is mixed directly with the total amt. of chromic acid. In the multistage process, the wax is initially mixed with chromic acid in an amt. corresp. to a CrO3:wax wt. ratio of 0.5-1:1, and the rest of the chromic acid is added in one or more stages with intermediate removal of spent oxidising agent. Compared with prior art processes, the reaction times are reduced and smaller reactors can be used, giving increased space-time yields with less wax degradation and thus lower chromic acid consumption.

Title: Biological cell fractionation - based on modular system of disrupter and fractionating centrifuges
Inventor: BRUNNER GERD PROF DR
IPC: C12M3/08
Filed: 1979-05-10
Abstract: The fractionation of biological cells by means of a cell disruptor is based on a continuous break-up of cells and a continuous passage of the fractionated material through one or several series-connected rotors (e.g. counterflow centrifuges with elutriator/rotor). Each cell fractionator is pref. assembled from modules of a fractionating centrifuge; representative modules would be the transformer electronic control, vacuum, diffusion pump, cooling, rotor chamber drive, reservoir/pump and detector. This facilitates the completion of a fractionator and makes it usable more universally. The modular system reduces the path to be travelled by the biological material.

Title: Ice cream portion scoop - with counter for every turn of the ice detaching wire loop
Inventor: PONTE BECHER BORTOLO DA
IPC: A47J43/28
Filed: 1979-06-15
Abstract: An ice cream dispensing scoop is a hemispherical cup in which a semicircular wire loop can be turned to detach the portion. The turning motion is carried out by compressing two pincer handles to move a rack attached to one handle relative to a pinion, supported on a bracket of the other handle. This pinion turns a shaft with the detaching wire loop at the end. Each operation of the pincers also moves a lever between two pins which advances the position of a mechanical counter by one digit. This is a simple device which can be produced at low cost. It provides an exact check of the number of ice cream balls issued by the salesman and cuts out any arguments. It also prevents them from playing with the tools empty and wearing them out.
