Patent DE-3806854-A1 (DE)
Inventor: RUF HEINZ DIPL PHYS DR
IPC: C04B28/14
Filed: 1988-03-03
Abstract: In a process, in which a flowing plaster mass of  alpha -calcium sulphate hemihydrate is the sole binder, of inert aggregate material, plasticiser, retarder and water is mixed, cast and, after setting, allowed to dry until cover-ready, it is desirable to produce a plaster which is cover-ready at an early stage from a flowing plaster mass in an economical manner. This is achieved by mixing, separately from the mixing with water, a dry mortar with at most 50% by weight of  alpha - calcium sulphate hemihydrate which has been obtained from the gypsum arising in flue gas desulphurisation, in the continuous autoclave process, and limestone free of a fines fraction below 40 mu m as aggregate material, and by subjecting the set flowing plaster mass to drying by means of an apparatus. The composition of this flowing plaster mass renders the production of a flooring from  alpha -calcium sulphate hemihydrate economically feasible, the drying-out being accelerated by the drying measure, so that the cover-ready state is reached earlier than hitherto and disadvantageous building delays are avoided.

Title: Coding of bobbin cases
Inventor: KATHKE GREGOR
IPC: B65H67/06
Filed: 1988-03-04
Abstract: The coding of bobbin cases in rough operation in spinning and winding must be permanent and easy to read. These requirements are achieved by the coding of the bobbin cases according to the invention. With it, an assignment or supply of spooled or unspooled bobbin cases to given textile machines which produce or process bobbins or to one or more workplaces of these machines is possible. To this end, the bobbin cases (6) are in each case equipped with an electric resistance element (32) of defined size. The value of this resistance is scanned at contact points (33, 34) and measured with the aid of a resistance meter (35). As a result, an assignment or supply to given textile machines or one or more workplaces of a machine is made possible, on which bobbin cases with the corresponding codings have been or are being used. <IMAGE>

Filed: 1988-06-14
Abstract: Method for the production of bag-type packages which are filled with stackable piece goods e.g. biscuits consisting of at least two stack rows R1 R2, in which firstly an under-weight bag filling is produced and the shortage amount is then added. Stack rows R1 R2 with approximately equal length are produced the total weight of which lies below the ideal weight, and are then piled up into a material group P which corresponds to one bag filling. The total missing weight is ascertained and the number of missing individual pieces resulting from the weight shortage is determined by the balance W and microprocessor M. The missing pieces are allocated to the stack rows e.g. by microprocessor controlled magnets Z1, Z2 so that one of the outer stack rows corresponds to the length of the bag width and the other missing pieces are allocated in staggered form to the following rows, a maximum of two pieces of material being allocated to each stack row and the bag filling thus formed being inserted with the longest stack row lying uppermost in the bag thus ensuring neatly shaped closure folds. P', P'', P''', and P'''' indicate how one, two, three, or four missing pieces are allocated to the stacks. <IMAGE>
