Patent DE-3618609-A1 (DE)
Title: Covering cap for wooden masts
IPC: E04H12/04
Filed: 1986-06-03
Abstract: The invention focuses on a plastic covering cap for wooden masts, by means of which the mast tip, bevelled in a roof-like manner for the purpose, is protected against the penetration of rain water and thus against rotting. Such caps are generally nailed on the mast tip, but moisture can penetrate into the wood along the driven-in nails, as a result of which the wood rots from the inside. Moreover, nails easily fall off during installation and are eaten by animals which then die. In order to avoid nailing-on, the invention proposes fastening strips 2, which rest on the mast circumference and are pressed onto the mast by means of a fastening band. For this purpose, the strips 2 exhibit means, e.g. eyelet-forming arched portions 16, which hold the fastening band during installation, and a toothing system 17 may be provided for securing the strips on the mast. The strips may be pushed in, by means of rectangular base flanges 14, from above through openings 9 in the legs 4 of the covering part 1 of the cap. <IMAGE>

Title: Device for increasing the efficiency of ships' propellers
Inventor: SCHMIDT DIEDRICH DIPL ING
IPC: B63H5/16
Filed: 1986-06-19
Abstract: The invention relates to the field of hydrodynamics in shipbuilding.   The object of the invention is to achieve a higher degree of efficiency of propellers and at the same time to produce an additional propulsion force. The invention is based on the object of achieving the most uniform possible distribution of the wash in the propeller disc by means of an appropriate, nozzle-shaped guiding device in front of the propeller by the largest possible amount of water being guided at a relatively high speed into the upper region of the propeller disc and deflected in an approximately axial direction. In order to achieve this object, the nozzle-shaped guiding body which is arranged at the stern of the ship in front of the upper half of the propeller disc is designed in such a way that it is formed from an approximately rotationally symmetrical upper part in the shape of a half ring which is securely connected to at least two flow guiding fins which form the lower termination of the nozzle-shaped guiding body.

Title: High-voltage cable having built-in pressure elements
Inventor: RASQUIN WERNER PROF DR ING
IPC: H01B9/06
Filed: 1986-07-07
Abstract: The invention relates to a high-voltage cable having a conductor (2) which is arranged centrally in insulation (8) having an inner and an outer guide layer (7 and 9 respectively), having a metal sheath (10) which is enclosed by a pressure binding (11) and a plastic outer sheath (12), and having built-in, elongated pressure elements. It achieves the object of creating a maintenance-free high-voltage or very-high-voltage cable (high-tension or very-high-tension cable) whose operating reliability is ensured without any requirement for external compensation vessels and/or pressure maintaining devices, and which can be laid without problems over great lengths on a pathless cable run or in the sea. The solution essentially comprises the construction of the pressure elements as mouldings (5 or 17 to 19) which are kidney-shaped or trapezoidal in cross-section and are twisted into the cable over each production length of the cable in at least one layer (14) which is adjacent to the insulation (8) and/or to the conductor (2). These pressure elements are installed with a gas overpressure or with spring force such that they always act with overpressure against the cable insulation (8) and prevent any cavities being formed therein. <IMAGE>

Title: Continuous dry-spinning and aftertreating process for highly shrinkable acrylonitrile filaments and fibres and such filaments and fibres
Inventor: REINEHR ULRICH DR
IPC: D01F6/54
Filed: 1986-09-05
Abstract: The invention relates to a continuous process for producing crimped, highly shrinkable filaments and fibres from acrylonitrile polymers containing at least 40% by weight of acrylonitrile units. For the purposes of the invention, a continuous process means that the filaments are in one operation, without interruption, dry-spun, spin-finished, steamed, drawn (stretched), crimped and optionally cut into staple fibres. The steaming and drawing of the spun material is effected without aqueous baths. The process can be carried out on heavy tows and at high production end speeds. The process is characterised in particular by the solvent residue removal by means of dry air or preferably superheated steam in countercurrent with low or no tension prior to the drawing and crimping process. This makes available essentially vacuole-free and vacuolisation-resistant fibres of enhanced density, a very low spin finish and residual moisture content, enhanced strength and excellent stability of the high shrinkage properties.

Title: Rapid signal detection, direction finding and locating device
Inventor: PFAFF KLAUS DR
IPC: G01S3/74
Filed: 1986-11-21
Abstract: Radio reconnaissance of the type practised until now using signal detection and direction finding is characterised by time-determining parameters which do not allow brief transmissions, which appear at any time and at any frequency, to be detected, their direction to be found and them to be located. The invention relates to a signal detection, direction finding and locating device which operates using fast signal detection direction finders, that is to say avoiding the otherwise normal detection receivers, at any station, initially with the aid of automatically time-related frequency tuning and detects all identifiable signals, the fusion of the resulting data being carried out in such a manner that further detection and direction-finding sequences are adaptively synchronised in time (that is to say the frequency band and frequency change per unit time) by means of correction measures which may be required. In comparison with the previous methods using conventional equipment and a conventional operating sequence, the device according to the invention achieves not only a reconnaissance speed which is increased by orders of magnitude but, at the same time, a reduction of the data flow which goes well beyond known measures (for example differential spectrum observation) as a result of the three-dimensional filtering which is also introduced.
Patent DE-3642939-A1 (DE)
Inventor: SPROAT BRIAN DR
IPC: C07H21/00
Filed: 1986-12-16
Abstract: A process for labelling DNA fragments (oligonucleotides) using fluorescent dyes. The labelling is carried out by converting the DNA fragment into its 5'-[HS-(Y)z]-derivative, and the latter is reacted with a derivative of a fluorescent dye, which together with the 5'-[HS-(Y)z]-derivative forms a DNA fragment of the formula (I) fluorophore-X-S-(Y)z-CH <SIGN>  -oligonucleotide, wherein X and Y independently are a group comprising one or more carbon atoms and/or hetero atoms, z = 0 or 1, and fluorophore is the residue of a fluorescent dye. In a preferred embodiment the DNA fragment is converted into its 5'-(S-triphenylmethyl-3-mercaptopropyl phospho)-derivative and the 5'-(3-mercaptopropyl phospho)-derivative obtained after cleavage of the triphenylmethyl group is reacted with a (5- and/or 6)-iodoacetamino-rhodamine or -fluorescein.

Title: Negating-complementing circuit in 5211 code
Inventor: MERKLE PAUL
IPC: G06F7/48
Filed: 1987-01-02
Abstract: The negating-complementing circuit according to the subject of the invention has an additional circuit (40), which is arranged in the input area. This additional circuit (40) is only effective if this circuit is pre-triggered for complementing, and if the potential series LHH is present at inputs A3 to A1. In this case, outputs B3 to B1 have the same potential series, because 4 - 2 = 2 and output B3 is not allowed to have high potential instead of outputs B1 and B2. This negating-complementing circuit also supplies complement number potential series which agree exactly with 5211 code. <IMAGE>
