Title: Lifting device for group-wise hanging of electrodes onto electrolytic baths
Inventor: LERCHENMUELLER PETER
IPC: B66C1/22
Filed: 1988-12-09
Abstract: The lifting device serves for groupwise hanging of electrodes onto electrolytic baths, for the purpose of electrolytic refining of copper. The device has a supporting frame (7) which can be lifted, lowered and displaced horizontally, and has a number of pairs of hooks (16, 25), whose number corresponds to the number of the electrodes and which pairs of hooks can be adjusted with respect to the supporting frame (7). The supporting frame (7) has three pairs of rails (10-10, 11-11, 12-12), the rails forming a pair each being situated symmetrically with respect to the vertical longitudinal centre plane of the frame (7). Two of the pairs of rails (10-10; 11-11) carry adjustable hook strips (13, 14), and the rails (12) of the third pair of rails (12-12) can be raised and lowered and have a comb strip (15) whose comb teeth are directed downwards. The rails (12) with the comb strips (15) are situated between the rails (10, 11) with the hook strips (13, 14). In this arrangement, the rails (12) having the comb strips (15), merely acted upon by influence of their own weight, adopt their bottom limit position with respect to the supporting frame (7) and can be raised against the action of their own weight. By means of this lifting device it is possible for the cathodes and anodes, which are arranged with very small spacings in the electrolytic bath and which successively alternate with one another, to be seized and lifted out or to be inserted, respectively, in a group-wise manner. <IMAGE>

Title: Method for controlling driverless transport systems
Inventor: PIETSCHMANN ERHARD DIPL ING
IPC: G05D1/02
Filed: 1988-12-23
Abstract: A method is specified for controlling driverless transport systems, a plurality of driverless transport systems being operated in an installation. These driverless transport systems are equipped with ultrasonic distance sensors for the detection of obstacles, which detect the distance of an obstacle on the basis of the transit time between a transmitted ultrasonic signal and an echo signal reflected from the obstacle and, in the case of undershooting a safety distance, the corresponding transport system is stopped. On the basis of the known intrinsic speed of the driverless transport system, a decision is made as to whether an echo signal is a passive echo signal reflected from an obstacle or an active transmitter signal transmitted by another driverless transport system. All transport systems are provided with different priorities (n = 0, 1, 2, 3...) and each priority has assigned to it a multiple of a device-specific waiting time (n.tOR), for which the operation of the driverless transport system is stopped when an active disturbing echo is received by the relevant transport system.

Filed: 1989-05-19
Abstract: (A) In a catalyst (1) consisting of a support structure (2) having a thermally sprayed layer of a multi-component catalytically active material, at least one component of which is heat sensitive, the novelty is that the catalytically active material layer comprises particles which, apart from the lowest melting component, are unfused.

USE/ADVANTAGE - The catalyst is esp. an anatase TiO2-contg.  oxidn. catalyst for NOx redn. in flue gases. An adherent, highly catalytically active coating is obtd. by thermal spraying without excessive heating of the heat sensitive component causing e.g. conversion of the anatase to a less active crystal structure or modification. Thick coatings can be produced.
Patent DE-3922181-A1 (DE)
Inventor: TISSLER ARNO DR
IPC: B01J29/70
Filed: 1989-07-06
Abstract: 2.1. Zeolites are microporous crystalline aluminosilicates which are distinguished by a number of particular properties. They have a defined cavity system with orifices of 0.3 to 0.9 nm. They are cation exchangers. In the H form, they have high acidity in the solid state. The hydrophobic character can be controlled by the ratio of silicon to aluminium. They exhibit high thermal stability. These substances were generally prepared only with the addition of organic, structure-controlling compounds to the synthesis mixture. Processes which dispense with the use of these organic substances, for example US 4,257,885, lead only very slowly (after several days) and generally incompletely to the desired product. Furthermore, the occurrence of undesirable secondary phases cannot in general be ruled out. The present invention relates to a purely inorganic synthesis process which virtually completely excludes the formation of secondary phases and which can be carried out in a short time. 2.2. The zeolites prepared by the process according to the invention have a chemical composition which can be described as follows in molar ratios: 0-3M2O : Al2O3 : 15-40SiO2 : 0-40H2O, in which M denotes an alkali metal cation. These zeolites can be subjected to exchange with the aid of a mineral acid, an ammonium compound, other proton donors or other cations. In conjunction with the above chemical composition and the interplanar spacings listed in Table I, the zeolites prepared according to this invention have, in the 29-silicon solid state Mas nuclear resonance spectrum, adsorption bands at about -100, -106, -112 and -116 ppm, based on tetramethylsilane as standard, with the aid of which this novel aluminosilicate can be distinguished from all similar zeolites (Fig. 1 and 2). 2.3. Because of these structural units, the zeolite catalysts prepared according to the invention have a much higher catalytic activity than similar pentasils prepared by conventional methods.  3.

The difference between the braking pressures for the same wheel axle is compared with a difference threshold dependent on the vehicle velocity, to allow the higher braking pressure to be reduced when the difference threshold is exceeded. Pref. the difference threshold is also dependent on the vehicle retardation. ADVANTAGE - Ensures safe braking.
