Title: Soluble, electrically conducting polymers, process for producing them and their use
Inventor: FELDHUES MICHAEL DR
IPC: C08G61/12
Filed: 1986-08-26
Abstract: The invention relates to intrinsically electrically conductive polymers which are completely soluble in the oxidised form in dipolar aprotic solvents at room temperature and which contain structural units derived from at least one monomer of the general formula (I) below: <IMAGE> in which at least one of the two radicals R<1> and R<2> is an alkoxy group and the other radical is optionally (C1-C6)-alkyl or hydrogen. Furthermore, the invention relates to a process for producing said polymer by electrochemical polymerisation of at least one monomer of said formula (I) in the presence of an electrolyte solvent and conducting salt. In this process the anode has a specific surface of at least 0.01 m<2>/g, the electrolyte solvent is dipolarly aprotic and the electrolyte system is not displaced relative to the anode or is only slightly displaced. The polymers according to the invention are well suited, in particular, for coating purposes.
Patent DE-3630635-A1 (DE)
Title: Packaging and dispenser for medical swab rolls and bandaging material
Inventor: ZANKER HELMUT
IPC: A61F15/00
Filed: 1986-09-09
Abstract: Bandaging material and cellulose swabs on rolls have to meet higher hygienic requirements as regards their packaging and storage, so that the possibility of microbial contamination is largely ruled out. To meet these requirements, the invention proposes a simple plastic packaging which is simultaneously designed as a dispenser, so that the agents packaged therein do not have to be removed and repackaged in the hospital or medical practice. For removal of individual swabs or strips of bandaging material the rolls together with their respective end-piece remain within the package until finally used. The individual devices can be inserted, by means of a simple mounting or clamp, selectively and as required on a wall rail or in a holder where they can be extended in any sequence to form a functional wall from which they can be removed at any time and carried to other treatment rooms. The emptied containers are then destroyed, being disposable containers. This innovation simultaneously takes into account the technical work requirements and the differences in space available in hospitals and medical practices, in an ideal and hygienic manner. <IMAGE>
Patent DE-3632958-A1 (DE)
Title: Electronically recordable and readable identification ring, particularly for carrier pigeons
Inventor: HEIMES HORST-PETER DR ING
IPC: A01K11/00
Filed: 1986-09-27
Abstract: To simplify and improve the timing of carrier pigeons, a novel identification ring is described which contains a microcircuit with an electrically recordable and electrically erasable semiconductor memory which can process serial data and receives data without power supply. The ring contains irregularly arranged contact zones which are scanned by contact pliers which forward the data present in the memory to a reading/writing device. These data are decoded or respectively encoded and transmitted, together with the time and date information of an internal crystal clock, to a serial interface where they can be processed further by an EDP system. The external system can also write into the control device and thus also directly into the memory of the ring. It is also possible to remotely control or correct the clock time. This novel invention prevents manipulation and input errors whilst at the same time considerably increasing the speed of the entire data and time acquisition process.
Patent DE-3635575-A1 (DE)
Title: Protective-blind device with transparent lamellae, in particular for forcing frames
Inventor: STIFFEL HERMANN
IPC: A01G9/22
Filed: 1986-10-20
Abstract: The invention proposes a protective-blind device in which the lamellae consist of a transparent material and by means of which the incidence of light is ensured in the closed state. For watering, ventilating, sowing and planting, there is no longer any need to lift up and secure a glass pane, because all that needs to be done is to adjust the position of lamellae or to draw them together on one side. Moreover, rain can be channelled in as watering water by positioning the lamellae obliquely.

Abstract: The termination on one end of a heavy, preferably screened, plastic cable, especially for mining use underground must be capable of connection in a sealed manner to an entry. Reliable sealing of the entry must be ensured even in the case of cables having a different cross-section. For this purpose, a pushed-on tubular sleeve (14), preferably consisting of PVC, is connected to the cable end, which sleeve (14) has a cylindrical end part (16) which faces the free cable end and whose outer surface is used as a mating surface for sealing (4) against the entry (1) and which has a short intermediate part (18) of smaller diameter at a distance from the free end, and which sleeve furthermore is provided at its end facing away from the cable end with a stop ring (19) of larger external diameter than the end part (16), the region of the stop ring (19) being seated on the outer sheath of the cable, and the adjacent part of the cable end, which is offset in a stepped manner and is enclosed by the sleeve (14), being potted using casting resin. Such a termination makes available a defined contact surface for sealing, different conductor cross-sections being bridged by potting with resin within the sleeve (14). <IMAGE>

Patent DE-3710507-A1 (DE)
Inventor: NEY HERMANN DR
IPC: G10L15/00
Filed: 1987-03-30
Abstract: Recognition is achieved by sequentially comparing speech values derived from the speech signal with reference values provided by the words of the vocabulary. With a large vocabulary the number of reference values is very large so that the number of hypotheses followed has to be reduced. To carry out this reduction in an effective manner, after each comparison of a new speech value, the distance sums thereby obtained are stored in a memory together with the number of the relevant reference value and of the backward vector; this memory is controlled by a list in another memory; each line of the list has the number of a word in which there is an active hypothesis, and the address in the first memory at which the first and the last reference values of a coherent range in which hypotheses are running are stored, with the relevant values. After comparison with a threshold value, the values still remaining are transferred into a further memory structured and addressed in the same way. For this purpose, word transitions and in particular syntactical limitations are taken into account. From the transferred values, supplemented where necessary, the minimum distance sum of the reference values lying within a predetermined vicinity are assigned to each reference value, allowing for a direction-dependent additional value, while at the same time the hypotheses are extended and then the results of the comparison of the reference values that then become active are processed with the next speech signal. In addition, special measures are specified to take account of speech patterns. <IMAGE>

Title: Mobile apparatus for applying a viscous composition to horizontal surfaces, such as roads, squares and the like
Inventor: HAUSKE GERHARD ING GRAD
IPC: E01C19/16
Filed: 1987-05-11
Abstract: An apparatus for coating a horizontal surface, for example a road, square or the like, is provided, on a chassis, with a hollow distribution beam which extends transversely over the working width and has, on its underside, a slot from which the coating composition emerges as a viscous composition and can be caught and distributed by a broom-like or brush-like distribution device. The arrangement can be made such that composition coming out of the slot is firstly distributed by the distribution device on the surface of a press-on and smoothing roller and is transferred by the latter onto the surface to be coated. It is however also possible for the composition to be applied directly to the surface to be coated by means of the distribution device and for the press-on and smoothing roller to travel over this layer.

Title: Process for purifying water contaminated with pollutants, especially hydrocarbons
IPC: C02F1/20
Filed: 1987-10-02
Abstract: The process for purifying water contaminated with pollutants, especially hydrocarbons, provides for the injection of carbon dioxide into the vessel containing the water. As the carbon dioxide rises in the form of fine and very fine bubbles, pollutant particles are entrained and carried to the water surface whence they can be drawn off. The process employs a closed vessel with an offtake duct downstream of which there is a filter installation. The chamber serving for the carbon dioxide treatment of the water to be purified expediently has a plurality of chambers connected downstream which act as backpressure stages.

Patent DE-3740490-A1 (DE)
Title: Positive-locking overload coupling
Inventor: KOESTER ROLF
IPC: F16D7/04
Filed: 1987-11-29
Abstract: Overload couplings serve to protect the drive motors or gears in the event of overloading. Secure and rapid separation of the two parts of the overload coupling is achieved in that the coupling parts are fitted, in the contact region, with carrier faces which act as carriers, point obliquely towards and away from the shaft and thereby form wedge and notch. One of these carrier parts is pressed against the other carrier part via the pressing-on part, the two parts being arranged axially relative to one another. The carrier faces resting against one another ensure that the torque predetermined in each case according to the pressing-on part is maintained before the overload coupling can respond in the event of overloading occurring. It is thus possible deliberately to transmit the increased torques which occur in the start-up phase, whereas the typical overload cases with excessive torque automatically lead to a rapid and reliable response of the overload coupling. <IMAGE>
