Abstract: The invention relates to an arrangement for supercharging a multi-cylinder internal combustion engine (1), the exhaust manifold of which engine (1) is divided into at least two separate sections (3, 4), each connected to a respective group of the cylinders of the engine. The arrangement includes at least two superchargers (5, 6), each comprising a turbine (7, 8) for connection to the outlets of exhaust manifold sections (3, 4), and a compressor (9, 10) which is driven by the turbine and the outlet of which is connected to the engine inlet manifold. The turbine (7, 8) in each supercharger (5, 6) is connected to the outlets of at least two exhaust manifold sections (3, 4) in a manner such that the pressure pulses in the exhaust gases from one section (3, 4) are supplied to the turbine (7, 8) substantially without influencing the course of the pressure in remaining sections (3, 4). A valve arrangement (25) is arranged upstream of the turbine (8), and a valve arrangement is arranged preferably upstream of the compressor (10) in at least one of the superchargers (6), this supercharger (6), or these superchargers (6), being smaller than the remaining superchargers (5).

Abstract: Daughter missiles 11 are catapulted forward from a mother missile 10 when a rocket motor 12 of the mother no longer accelerates the missiles. A catapult force generated at a piston head 43 by the pressure of gas from the rocket motor on rearward facing surfaces 26 of the daughters is large enough to shear pins 34 holding the daughters to the mother, but only when the forces of reaction of the daughters 11 on the piston 43, due to acceleration, have fallen off. Preferably the daughters are thrown outwardly at release, most preferably by axial spinning of the structure of the mother to which they are mounted.

Abstract: A monocrystalline semi-conductor layer (7) is sintered firmly to an oxide layer (6) on the epitaxial layer, and the thus produced body is coated with a nitride layer (8a) and an organic polymer layer. The lower part of the nitride, layer and the oxide layer is etched away, and then the main part of the semi-conductor plate is etched away with sodium hydroxy-soln. A residue of the semi-conductor palte is etched away with a doping-selective etching soln. which does not etch into the eipthaxial layer. This is demonstrated by photolithographic methods, and the required parts of the layer are etched away with anisotropic etching fluid so that semi-conductor islands (2) remain. The freed surfaces (2b,5b) of the islands are doped and oxidised to an insulating oxide layer (3), and the base (1) is deposited. The nitride layer (8a) is etched away in company with the semi-conductor layer so that electronic components can be produced in the semi-conductor islands.

Abstract: The male part (2) is connected at one end with a safety line (6), whilst its other end inserts into the female part (3) telescopically to a specific depth. The other end of the female part fixes into a key holder. The two parts have a circular cross-section, and are formed partly with diametrically orientated bayonet lock-type slots and partly with axially movable spring-loaded lock components. The straight part (1a) of the key ring is inserted in the slots which run radially and have a peripheral section corresp. to a predetermined rotation angle, for the one part clockwise, and for the other anti-clockwise. The lock component is activated by pressure on the opposed parts to free the slots so that the key ring can be inserted in them. Activated only by spring loading, the lock component bridges an outer part of the peripheral section of the slots so that a key ring is retained in them.

Abstract: A system for natural language (NL) analyzis is provided which comprises apparatus and method. It has the capability to analyze NL expressions and to resolve ambiguities and present them to the user for verification of correct interpretation. The invention is based on a language independent model of the contents of a data base. The model contains records of information defining entity types and relations between such entity types. The model is created (customizing the system) by the user, and is stored as a conceptual schema. The entities of the schema are linked or connected to natural language terms in a vocabulary. The entities represent objects in the data base, and there is a link or connection between the entities and those objects of the data base. The actual analysis of NL expressions is performed by a Natural Language Engine (NLE) in cooperation with an Analysis Grammar and the schema. The analysis results in an intermediate, language independent logic form representation of the input, which is paraphrased back to NL for verification, and if the input is a query, there is a translation into a query language such as SQL.

Abstract: The tongs have two parallel jaws, a housing, and an arm movable relatively to the housing. Under the influence of the movable arm, the jaws are moved towards one another. A generator circuit is located in the housing, and applies a high frequency voltage between the jaws, causing the hose to melt whilst the jaws are clamped around it. - The generator circuit comprises an oscillator, an amplifier, a transformer, and a time circuit. It applies the high frequency voltage for a period of approximately 0.5 to 2 seconds. The high frequency signal has a frequency of around 40 MHz, and a voltage of between 150 to 250 volts. A rectifier is located separately from the tongs, and supplies the tongs with direct current via a conductor. This current has a voltage of 10 to 15 volts, which the transformer transforms to the higher level. - The time circuit, on receipt of a signal from a micro-switch, emits a signal starting the oscillator and amplifier, and a further signal to stop them after the predetermined time of 0.5 to 2 seconds.

Abstract: In the laying of straight stretches of heat insulated district heating pipes it is known that the usual problems with respect to thermally conditioned expansions and contractions can be entirely avoided, if the pipes are of annealed copper with its associated special and relevant relaxation properties. With the invention it has been found that much cheaper pipes (2) of aluminium have similar properties, whereby these pipes are applicable when only a galvanic insulation (8, 10, 36) is provided between the pipes and the surroundings for counteracting galvanic corrosion. It is disclosed how this is achievable with particularly developed pipe joints, and it is emphasized that the pipes will be well suited to be mounted in the ground without the digging of trenches, viz. in being shot through the ground between wells (18, 20) spaced e.g. 50 m or more from each other.
