Patent DE-19520547-A1 (DE)
Title: Measuring volume of any shaped body using closed tubular hollow body e.g. for gold jewellery
Inventor: GROS J DR
IPC: G01F17/00
Filed: 1995-06-06
Abstract: In the cavity in which the body to be measured is introduced, a sound resonance is also produced with a selected phase relationship. The vol. of the body is determined from the two resonance frequencies and the vol. of the cavity. A second resonator is arranged in the cavity, the resonance frequency of which cannot be influenced by the body being measured. This second resonance frequency is used as the frequency norm for the longitudinal resonance. The gas pressure in the measuring tube can be altered.

Title: Desulphurising flue gas from coal fired power stations
Inventor: PFEIFFER JUERGEN DIPL CHEM
IPC: F23J15/04
Filed: 1995-06-16
Abstract: DE19502632-A describes a process for desulphurisation of flue gas from coal fired power stations by scrubbing the gases with a suspension of quicklime and sulphate-enriched process water introduced into the sump and spray inlets of a gas scrubber, and controlling the pH of the suspension in the sump of the scrubber and in the spray levels to greater than 6.5 depending on the SO2 content of the flue gas. The process is now improved by controlling the pH of the suspension to an upper limit of less than 8.3, and operating the gas washer until the pH is in the region of the upper limiting value relevant to the individual installation.

Patent DE-19535450-A1 (DE)
Inventor: FLOOD GERALD
IPC: C07C29/76
Filed: 1995-09-23
Abstract: The invention concerns a process for separating solids from aqueous 1,4-butyne diol solutions by trickling a solids-containing aqueous butyne diol solution through a column and so bringing it into contact with a solvent which has lower density than the solids-containing butyne diol solution and forms a second phase therewith. The solvent rises in counter-flow to the aqueous butyne diol solution, the solids accumulate at the interface between the aqueous butyne diol and the solvent, and the solids are removed from the column by removing a mixture of aqueous butyne diol and solvent.

IPC: D21C9/10
Filed: 1996-04-13
Abstract: The invention relates to a method for the bleaching of lignocellulosic fibers wherein lignocellulosic fibers are treated with at least one oxidizing bleaching chemical in aqueous solution. The invention also relates to the application of additives for bleaching lignocellulosic fibers and to the application of an aqueous solution containing at least one additive for bleaching lignocellulosic fibers. In the context of this paper, the term "lignocellulosic fibers" includes all sorts and types of pulp like e.g. chemical and mechanical pulp, dissolving pulp or pulp prepared from waste paper but also natural fibers like cotton or flax fibers. The method for bleaching of lignocellulosic fibers according to the invention is characterized in that lignocellulosic fibers are treated with at least one oxidizing bleaching agent in aqueous solution in the presence of at least one additive which activates delignification and/or bleaching, the additive being selected among the phenanthrolines and/or polypyridyles. The method is applicable to all known oxidizing bleaching agents like oxygen, ozone and/or peroxo-chemicals or mixtures thereof especially for peroxo-chemicals which comprise hydrogen peroxide, sodium peroxide, perborates, performic acid, peracetic acid or caroic acid and/or salts thereof.
Patent DE-19621196-A1 (DE)
Inventor: BRAUNECKER BERNHARD DR
IPC: G01S17/66
Filed: 1996-05-25
Abstract: The invention concerns an optical sensor (50) for tracking an aiming mark (10) using an optical radiation source (6) and a high-sensitive resolution optoelectronic detector (7). To guide the radiation beam, optical elements (2a, 2b, 2c, 3a, 3b, 3c) are integrated monolithically on or in a base body (1). The radiation beam is directed from the base body (1) and is reflected by the target (10) before it is again received by the base body (1). The monolithic integration of the optical elements (2a, 2b, 2c, 3a, 3b, 3c) enables the tracking sensor (50) to be miniaturized, thus reducing manufacturing costs and weight and consequently improving tracking speed, space requirements, stability and manufacturing reliability. The optical elements (2a, 2b, 2c, 3a, 3b, 3c) may be reflective, refractive or diffractive. Moreover, instead of the radiation spot (20) an intensity pattern may be generated on the detector (7) by a monolithically integrated optical element, thus improving the accuracy of measurement and coverage of the tracking sensor (50).
