Patent DE-3344056-A1 (DE)
Title: Beacon
Inventor: SCHOEN OTTO DR
IPC: E01F9/688
Filed: 1983-12-06
Abstract: Road traffic beacons serve for marking the edge of a roadway changing its direction or width. Usual beacons consist of a heavy foot which supports a vertical rod, on which the beacon plate having the warning symbol is fastened. These beacons are very dangerous because they can seriously damage a vehicle which only brushes past. The beacon according to the invention avoids this disadvantage in that the warning symbols are applied not to a rigid plate but to the elastic outer surface of a rubber or plastic bag which is sealed in an airtight manner and which is tightly filled with a light compressively elastic substance (e.g. air or foam) and which is fastened standing upright on a flat base plate to be anchored at the roadway edge. In order that the beacon is easier to observe in the dark, the bag can consist of light-permeable material and be illuminated from inside by an upwardly radiating light source fastened to the base plate. To increase the standing security, the bag interior can be divided into a number of airtight longitudinal chambers.

Title: Self-adjusting narrowband receiver
Inventor: BERMBACH RAINER DIPL ING
IPC: H03J7/02
Filed: 1983-12-21
Abstract: Unlike the self-adjusting narrowband receiver described in the main application, the resonant frequency and quality can be controlled and adjusted with simpler algorithms and thus with less memory space by means of special feedback, designed as a controlled current source, in the audion circuit and by means of frequency conversion of the signal after the audion circuit and by subsequent amplification. Complete interference-suppression of the receiver can furthermore be achieved by operating the audion circuit during adjustment below the freely oscillating state and, following a search through a predefined frequency window, the transmitter having the matching modulation is adjusted.

Title: Recovery of metal compounds from used catalysts, obtained from hydrogenation processes for hydrocarbon charges
Inventor: GANGULI PARTHA SARATHI
IPC: B01J38/00
Filed: 1984-04-12
Abstract: A method for recovery of valuable metals such as, for example, primarily nickel and vanadium, precipitated on used catalysts of catalytic hydrogenation processes for metal-containing hydrocarbon charges. In the method, the used catalyst containing metal precipitates is treated with a fresh dilute acid solution such as, for example, sulphuric acid, in order to extract and remove the metallic precipitates without damaging the catalyst, whereupon the resulting spent acid solution containing the metal salts is neutralised to a pH of from approximately 3.5 to 12, using a hydroxide solution in a sufficient amount to form a metal salt precipitation material. The precipitation material is removed from the liquid, for example by filtration, and the precipitate is then heated to drive off water vapour and water of hydration, the oxides of metals such as, for example, nickel and vanadium remaining as the products. If nickel oxides and vanadium oxides are required to be isolated separately, the metal oxide material can be further heated in the furnace, together with carbon, to the corresponding melting points of the metals which, consecutively, are separately discharged from the furnace. Alternatively, the spent acid solution containing the metal salts, in order to remove nickel oxide and vanadium oxide separately, is first ... with a ... Original abstract incomplete.

Title: Catamaran
Inventor: WIESER RUDOLF DR
IPC: B63B1/12
Filed: 1984-05-29
Abstract: The invention relates to the creation of a power-driven catamaran for high speeds and for high manoeuvrability, which can be used both on rivers and at sea and which is completely seaworthy even with larger dimensions and in rough seas. The main feature of the proposal is the joining of the two floating bodies by means of several trusses or by means of a three-dimensional trussed frame and the arrangement of the platform or the cabin on these trussed structures at a sufficient height above the water level. Two cabin forms are also disclosed which have a reduced air and water resistance. For the floating bodies, a configuration is proposed which guarantees full planing capacity and adequate stability at high speeds and in addition permits high manoeuvrability of the vessel. For a military version of the craft, an armoured cabin is proposed which provides the crew with an especially high degree of protection.   <IMAGE>

Patent DE-3504923-A1 (DE)
Title: Sparkless ignition plug for internal combustion engines
Inventor: JOHN GUSTAV
IPC: F02P23/00
Filed: 1985-02-13
Abstract: The ignition plug according to the invention does not produce any extremely hot high voltage sparks, thereby preventing the occurrence of pollutant nitrogen oxides in the engine exhaust gases. Ignition occurs due to a rhythmically flashing and electrically heated glow wire of extremely low thermal inertia. In order to achieve a very precise firing point an extremely sharp temperature rise is necessary which is produced by a greatly increased supply voltage. The otherwise unavoidable burning out of the glow wire is prevented by an electronic circuit, which registers the quantitative luminous flux or the spectral colour of the glow wire and when a limit is reached abruptly cuts off the current supply to the glow wire.
Patent DE-3507842-A1 (DE)
Title: Mechanical centrifugal force drive for vehicles of all types
Inventor: SCHERBAUM HELMUT DIPL ING
IPC: F03G3/00
Filed: 1985-03-06
Abstract: By combining the uniform and opposing rotations of weights on orbits which are themselves rotated uniformly and in opposite directions, a pulsating mass action force (centrifugal force) is produced in a reference direction. This mass action force is independent of the wheel rolling friction (state of the road) or other propulsion elements and owing to the quadratic function of the speed has a low power demand for relatively large drive forces.

Title: Blow moulding machine for the production of hollow bodies from thermoplastic
Inventor: REUEL HERMANN
IPC: B29C49/24
Filed: 1985-09-07
Abstract: If, in plastics blow moulding machines, the finished plastic hollow bodies, for example bottles, are to be provided with labels, it is advisable to introduce the label or labels into the mould cavity or mould cavities of the open blow mould disposed in the blowing station before a parison is received. However, there is usually insufficient if any space available around the blow mould for the labelling device, because this space is blocked for the movement of the blow mould from the blowing station into the parison receiving station, for the blowing and calibration device and other functionally important devices, apparatuses and parts. The invention therefore provides that the labelling device 12, in its stand-by position, be arranged behind or in front of the blow moulding device 3 in the blowing position in the blowing station and the blowing device can be moved from the blowing station into an intermediate station disposed in front of a finishing station or in front of the transfer station for the finished hollow body and back and, at the same time, the labelling device can be moved from its stand-by position into the blowing station and back. In a preferred embodiment, the blowing device and the labelling device are joined by a guide rod system 13, 15, in such a manner that when the blowing device is moved from the blowing station into the intermediate station the labelling device is pivoted from its stand-by position into the labelling position in the blowing station. <IMAGE>
