Patent DE-4306382-A1 (DE)
Inventor: BREUERS WERNER DR
IPC: C08F4/654
Filed: 1993-03-02
Abstract: Bead-form polymers can be obtained in the polymerisation of alpha-olefins by using a highly active, spherical Ziegler catalyst based on a dialkylmagnesium compound. A further advantage of the novel catalyst is the high catalyst activity, meaning that only very small amounts of the catalyst are necessary for the polymerisation. The residual content of titanium and/or zirconium in the polymers prepared according to the invention is less than 10 ppm. Its very good hydrogen sensitivity means that the catalyst is particularly suitable in two-step processes for the preparation of polymers having a broad, bimodal molecular weight distribution. The replacement of sulphur-containing electron donors, such as diethyl sulphite, by alcohols, such as ethanol, results in lower odour nuisance and a broadened range of possible applications of the polymer. The spherical shape of the particles and the consequent very good flow properties of the polymers and copolymers mean considerable simplification and advantages during handling, drying and processing.   <IMAGE>

Title: Method for the electrochemical treatment of contaminated soils and/or ground water
Inventor: JEHRING HARRY DR
IPC: C02F1/461
Filed: 1993-03-01
Abstract: The method according to the invention is distinguished by the contaminated soil being rinsed with an electrolytic fluid and the residual contamination being immobilised, the transport of the electrolytic fluid, of the pollutants and of the immobilising agent being effected under the influence of an electric field in the soil. To protect metallic useful objects in the soil, the potential of the objects to be protected is set to the protective potential by local arrangement and/or electrical connection with the sanitation electrodes. The method according to the invention avoids the drawbacks of the prior art, possible threats to metallic useful objects (structural components, reinforcements/armourings, pipelines, containers etc.) due to stray-current corrosion (electrocorrosion).

Patent DE-4318327-A1 (DE)
Title: Gas sensor
Inventor: MEIXNER HANS DR
IPC: H05B3/26
Filed: 1993-06-02
Abstract: In order to set the desired operating temperature of up to 1000 DEG C and maintain it independently of external influences, gas sensors based on semiconducting metal oxides are conventionally actively heated with the aid of a resistor element (8). However, during the heating, mechanical stresses may build up in the sensor which are so large that its substrate tears and it is thereby destroyed. The object of the invention is to provide a gas sensor in which no mechanical stresses which impair the sensor function build up during heating and operation. By using a resistor layer (8) consisting of titanate, local overheating effects of the sensor substrate (1) and thereby large temperature gradients are avoided. The temperature dependence of the electrical resistivity of titanate ensures that the heating power is reduced in hot sensor regions, but comparatively more heat energy is supplied to colder sensor regions. Motor vehicle exhaust gas sensors. <IMAGE>

Abstract: The invention relates to a method for monitoring the functioning of illumination devices (NL) which can be controlled (driven, activated) via two power supply lines, in particular emergency illumination devices, having a centrally located DC and/or AC supply. In a test cycle, a plurality of pulse packets (IP...) for resetting a counting stage (ZT) in a peripheral module (PER) assigned to the respective illumination device are transmitted by a central control device and the readiness for operation of the illumination device (NL...) is reported back, by a specifically controllable response pulse (AI), to the central control device. A method of this type is used for monitoring lamps, in particular in emergency illumination devices (standby illumination devices). <IMAGE>
Patent DE-4322186-A1 (DE)
Inventor: SCHWARZ SIGFRID PROF
IPC: C07J53/00
Filed: 1993-07-03
Abstract: The invention concerns 14 alpha ,15 alpha -methylene oestradiol esters in which the 17-hydroxy group and/or the 3-hydroxy group is esterified. These esters are suitable for use, in conjunction with pharmaceutical auxiliaries, as drugs, in particular as contraceptive agents or anticlimacterics. They exhibit an oestrogenic action which is precisely defined compared with that of ethinyl oestradiol or naturally occurring oestrogens, and are preferably administered orally. Not only are the side-effects of customary contraceptive agents thus reduced, but oestrogen-substitution therapy is significantly improved.
