Title: Planner for monitoring time limits and arrangements
Inventor: LANGER MANFRED
IPC: G09B29/00
Filed: 1983-03-12
Abstract: In order to avoid the disadvantages, which exist in known systems, of non-movable time-limit recording and planning, there are in the metal chassis of the planner two spools, on which a writing surface is wound up. The writing surface is printed with a year calendar. By actuating the advance spool, the writing surface is set to the latest date, as a result of which all entries on the writing surface move automatically to the time limit line. Four months are always visible on the writing surface. By displacing the time limit line, it is possible clearly visibly to represent e.g. 1 month for exceeding time limits and 3 months for planning time limits. The entire writing surface is divided by horizontally tautened round rubber bands into compartments of different size. By actuating the reverse spool, it is possible to trace back up to 12 months time limits and arrangements met, as all entries on the writing surface remain. After expiry of the year, filing of the complete spool is easily possible.

IPC: C01F7/22
Filed: 1983-06-18
Abstract: The invention relates to a process for the preparation of pure aluminium oxide by digesting clays or alumina-containing minerals with hydrochloric acid. The aim of the invention is to remove all the acid-soluble alkali metals and alkaline earth metals, coming forward with the clay, together with the crystallisation mother liquor. The invention is based on the object of processing the dust contained in the decomposition gases to give a solution which is as rich in AlCl3 as possible and as low in HCl as possible, or to give solid AlCl3.6H2O. According to the invention, the object is achieved when the fine-granular dust from the exit gases of the thermal decomposition of the crystallised product is converted by washing with suitable AlCl3 solutions into an AlCl3-rich, HCl-poor solution or solid AlCl3.6H2O, the resulting quantity of solution or crystals being removed from the washing solution circulation and the quantity of HCl required to be discharged and a part of the required water being condensed out of the decomposition gas by suitable temperature control.

Title: Process for the purification of flue gas
Inventor: VOGG HUBERT PROF DR
IPC: B01D53/68
Filed: 1983-07-05
Abstract: The invention relates to a process for the purification of flue gas which results from the combustion of wastes and contains both solids of the most wide ranging composition and also pollutant gases and heavy metals in gaseous form, in which process the chief solid fractions are removed from the flue gas in a separation plant and are collected as fly ash and in which the flue gas is scrubbed for the purpose of binding pollutant gases of the remaining solids fractions, in particular in the slag. The object of the invention is to offer a process in which not only the gaseous heavy metal pollutants but also primarily the heavy metal pollutants present in soluble form in the fly ash and slag can be eliminated in the flue gas purification in as compact a form as possible from the flue gas purification process, where at the same time a good purification from HCl, SO2, NOx can be achieved or even improved. All other residues are to be capable of being recycled. The solution lies in that a remainder of the heavy metal fractions not bound in the slag is isolated from the slag by a weakly acid after treatment.

Title: Parts cleaning device
Inventor: HAMMANN MANFRED
IPC: B08B3/04
Filed: 1984-01-25
Abstract: A parts cleaning device has a parts cleaning basket (10) which can be rotated in a first direction by a first liquid jet (13.1) which acts on a drive vane (12) and in the opposite direction by a second liquid jet (13.2). The revolutions of the basket (10) are measured by a revolution counter (22) which emits to a control circuit (20) a first changeover signal (US1) when a predetermined number of revolutions in one direction has been reached and a second changeover signal (US2) when the set number in the other direction has been reached. The control circuit (20) then changes over the liquid feed so that always only one of the two liquid jets (13.1 or 13.2) is delivered. The direction of rotation of the basket (10) is thus continually reversed, thereby reliably avoiding a maximum permissible number of revolutions being exceeded. <IMAGE>
