Title: Test method for ferromagnetic powders
Inventor: UHLE KARLHEINZ DR
IPC: B03B5/44
Filed: 1981-04-11
Granted: 1984-10-18
Abstract: The invention relates to a method permitting ferromagnetic powders for use in heavy medium suspensions for the float-sink dressing of minerals to be readily tested as to their efficiency in magnetic separation and demagnetization. To this end, the invention provides (a) for a heavy medium suspension specimen to be removed from the purification cycle directly downstream of the magnetic separation stage, for it to be freed from impurities by decantation, and its relative sedimentation velocity to be determined with the aid of a sedimentometer; (b) for a heavy medium suspension specimen to be removed from the purification cycle downstream of the demagnetization stage, for it to be freed from impurities by decantation, and for its relative sedimentation velocity to be determined with the aid of a sedimentometer; and (c) for the heavy medium suspension specimen according to (b) to be demagnetized in a cyclicly decreasing magnetic alternating field with a maximum field strength which is 1.1 to 1.5 times the maximum field strength of the magnetic separator, and for the relative sedimentation velocity of the specimen to be determined with the aid of sedimentometer. The ferromagnetic powder is reliably separable magnetically and demagnetizable with the aid of a demagnetizing means in the event of the relative sedimentation velocity according to (a) being at least ten times greater than the relative sedimentation velocity according to (c), and the relative sedimentation velocity according to (c) being at most 10% lower than that according to (b).

Title: Process for the preparation of carboxymethylated alcohols, ether alcohols, thioalcohols or alkyl phenols
Inventor: SPRINGMANN HERMANN DR
IPC: C07C67/00
Filed: 1983-06-18
Granted: 1985-11-28
Abstract: A process for the production of carboxymethylates comprises reacting alcohols, ether alcohols, or alkyl phenols with an aqueous solution of at most a stoichiometric amount of free chloroacetic acid and twice the stoichiometric amount of an aqueous base. The chloroacetic acid and base are added separately, but simultaneously under agitation (at elevated temperature and under reduced pressure) to the alcohol or alkyl phenol.

Title: Dispenser package
Inventor: REDMOND SANFORD
IPC: B65D75/58
Filed: 1983-09-20
Granted: 1988-02-11
Abstract: A dispenser package (10, 100) for flowable substances of the type where the flowable product is contained within a flexible pouch (22) adhered to a relatively stiff material (12) and may be opened along a fault line (24) or cut pattern scored in the relatively stiff material with one hand by folding the stiff ends towards one another into a "V" shape containing one or more dimples, pyramidal shapes (26) or other protrusions on the fault line (24) or fault area. The protrusions (26, 40, 52, 54, 56) not only increase and concentrate the stress forces, so that even very tough, high barrier materials may be used in constructing the package and will rupture at the protrusions by the aforesaid folding motion, but also control both the aperture shape and flow direction of the flowable substance as it is dispensed. The ability to make the package of tough materials enables the package to contain substances under pressure which subsequently will be dispensed. A sponge-like material (65, 70) also may be compressed within the package shaped so that a ' portion (66) will project from the package on opening for use as a swab for application of the contents.

Granted: 1988-06-16
Abstract: An engine or a similar torque generator with internal torque M1 and moment of inertia T1 and an electrical drive with electrical torque M2 and moment of inertia T2 coupled thereto interchange an interchange torque MA over a coupling according to the equation M1=(MA) (1+(5 T))2(12+(T1/T2))-M2,(T1/T2). Based on the actual values MA and M2 as well as a parameter (T1/T2)* and a model time constant T*, a model value M* is computed in accordance with this function, which indicates the actual internal torque if said parameters correspond to the actual parameters. Thus, using supplemental set values  DELTA M2 the preset electrical torque is varied and the parameters calibrated in such a manner that the effect of the M2 variation on the model value virtually disappears.
