Abstract: The invention is for a flat electrical heating resistance element, so called foil elements. Elements according to the invention can be used for many purposes, however, it is specially intended for use as heating elements for water beds. The object of the invention is to minimize the electromagnetic fields caused by the elements. The influence of such magnetic fields on humans is on the whole unknown why there is a common desire that the strength of these magnetic fields shall be as low as possible in order to minimize effects, if any. Heating elements according to the invention have electrical resistance wire or band placed in loops on a plastic foil surface, whereby the loops have four with each other parallel conductors, electrically connected so that in any given moment the direction of the current in the two outer conductors are in the same direction and in the two inner conductors in the same direction opposite to the outer conductors.

Abstract: A three-point safety harness for use in a motor vehicle consists of two safety belts, each having its own individual retractor mechanism, the retractor mechanisms being mounted on the side of the relevant seat which is furthest from the associated door of the vehicle. One safety belt extends to a carriage movable along a rail mounted on the roof of the motor vehicle extending over the door opening. This safety belt is to form a chest strap. The other safety belt extends to a carriage movable along a rail formed in the door of the motor vehicle. This is the lap strap. The two straps are connected together by means of a slidable element which defines a passage or passages through which the safety belts pass in a sliding manner. The safety belt that forms the lap strap has a thickened portion which cannot pass through the said element. The safety harness if of the "passive" kind and the arrangement ensures that the belts are kept free of the seat when the door is open and the person using the harness is getting into or out of the motor vehicle.

Title: Gas aircraft motor with stator and rotor - has compressor wheel in rotor and is driven directly by combustion gases
Inventor: ILIUTA RADU
Filed: 1988-08-12
Abstract: The drive of the compressor wheel by combustion gases does not involve the use of a turbine. Using a so-called 'intermistic cooling system', and by reason of the compact format of the rotor, the combustion temp. can be raised to a high level, thus improving the engine performance. The motor can be built with an incorporated starter motor/generator, and with a fan, for use in vertical take-off and landing type aircraft. Using a feed-back diffuser method for air compression, the pressure can be increased 25 times.

Abstract: The rear wall (6) of the trolley basket is hinged under the top edge, just under the handgrip (5), to swing up when another trolley is pushed into the basket from the rear, for stacking. The bottom edge of the rear wall has a hinged wall (9) which swings forwards to become the sloping rear support for a folding seat (11) for a child. The top of this rear support has a shaped extension (16) which eases the folding action on stacking. The extension has a spring loaded mounting on the top of the rear support. It strikes the handgrip of the trolley it is being pushed into. The sprung extension then causes the rear support to fold flat before the rear wall is swung up with the support.  ADVANTAGE - Simpler stacking action, simple construction.

Abstract: The invention relates to an internal combustion engine 1 and a method of supercharging an internal combustion engine 1 with a turbo unit 4 consisting of a turbocompressor 6 and an exhaust-gas turbine 5 where the turbine 5 is driven by a first 2 of two cylinder groups 2, 3 forming part of the engine 1 and the compressor supplies supercharged air to all the cylinders 25 in both the cylinder groups 2, 3. The invention makes it possible, in for example a V- engine, to use only one turbo unit 4 with a reduced exhaust pipe run in the engine space. In a preferred embodiment, regulation 13, 14, 30 of the intake air pressure is effected between the cylinder groups 2, 3 so that the cylinder group providing the exhaust gases which are driving the turbine 5 receives an intake air pressure higher than that for the cylinders 25 of which the exhaust gases are bypassed around the turbine 5 directly to any catalyst 27 and silencer arrangement 28. In this way, it is possible to achieve inter alia essentially the same degree of filling in both cylinder groups, which results in simpler fuel control to achieve the same additional torque on the crankshaft of the engine from both cylinder groups. <IMAGE>

Abstract: The invention relates to an arrangement for a cooling system for cooling telecommunications equipment. This is installed in rack cabinets positioned one after the other. A duct section (4) is present beneath each rack cabinet. The duct section is so arranged as to direct at least one jet of cool air (6) upwards along the front wall of the rack cabinet. This is executed with openings through which the cooling air can reach the equipment. The duct section (4) is so arranged as to support the rack cabinet at four support points (4b1) at the respective ends of the duct section (4). In conjunction with this the walls of the duct section (4) are reinforced locally in order to withstand the load. In this way the duct section (4) exhibits a smaller flow cross section in the end areas (4d, 4e) than in a central area (4f) situated between the end areas. A gentle transition is provided between the central area (4f) and the flow surfaces of the end areas (4d, 4e). The front area (4a) of the duct section (4) lies in the same plane as the front wall of the rack cabinet. A number of upward-facing gills (4a1) is arranged in the central area (4f) in order to produce the upward-facing jets of cool air. The cool air unit produces an excess pressure inside the cooling duct, which has an approximately constant level of static pressure.

Abstract: The present invention relates to a method for distribution of cryptographic keys by using public-key handling in a cryptographic method for data communication in a hierarchical communication network, which comprises nodes in the form of administrators and final operators. An identity in the form of a unique prime number which is known to all administrators and final operators is associated with each administrator in the tree. The main administrator of the tree selects one or more directly subordinated administrators. He also selects a basic secret which he keeps secret. The main administrator creates a subsecret for each directly subordinated administrator based on his own secret and the identity of each directly subordinated administrator. The subsecret is allocated to the associated subordinated administrator and he keeps it secret. In a recursive method, subordinated administrators in turn select in a corresponding manner subordinated administrators and create subsecrets for them. The final operators are allocated a pair of keys by their respective administrators, consisting of a private key, selected in a manner similar to the manner in which the identity of subordinated administrators is selected and a public key created in a manner corresponding to the manner in which a subsecret for a subordinated administrator is selected or vice versa.
