Abstract: The present invention relates to a welding method in the manufacture of a spirally wound tube having a thermoplastic pro-file (1) of a mainly rectangular cross-section. A hole profile (1) is wound in a screw line form manner on a welding drum (2) si-multaneously as profile surfaces (1a, 1b), which are to be welded together are heated with hot air to a desired temperature, wher-eafter a welding mass (S) is extruded onto the heated profile surfaces (1a, 1b) in two streams along each edge of the profile surface (1a, 1b) and the welding mass coated hole profile portions are pressed together by means of a press roller (10). The inven-tion is characterized in that the welding is performed with a welding head (3) coupled to an extruder and provided with a welding keel (4), which from the outside is inserted between two profile surfaces (1a, 1b) to be welded together. Hat air (L1, L2) is blown out through two pairs of air openings (5, 7) in the welding keel (4) against the edge portions of the profile walls (1a, 1b). A keel nose (9) located between the two pairs of air openings is arranged to guide the four hot-air streams (L1, L2) and to pre-vent heating of the middle portion of the profile surfaces (1a, 1b). The extruded welding mass (S) is pressed out on the heat-ed portions of the profile surfaces (1a, 1b) through two pairs of welding mass openings (6, 8) in the rear section of the weld-ing keel (4). The welding pressure is maintained on a desired level by regulating the friction between the hole profile (1) and the welding drum (2).

Title: Process for producing an iron melt
Inventor: GRUENBACHER HERBERT
IPC: C21B13/14
Filed: 1995-04-10
Granted: 2001-01-23
Abstract: In a process for producing an iron melt, iron ore is reduced to sponge iron in a direct reduction zone. The sponge iron is melted in a meltdown gasifying zone while supplying carbon-containing material under gasification of the carbon-containing material to reducing gas and under formation of a slag. The reducing gas is injected into the direct reduction zone, is reacted there and is drawn off as a top gas. The reducing gas and/or the top gas is subjected to gas scrubbing and the sludges separated during scrubbing are admixed with binder and coal dust and subsequently are agglomerated. In order to be able to supply back to the direct reduction process in large amounts sludges incurring in the direct reduction of iron ore without disturbing the process course of the direct reduction in any way, the sludges separated during scrubbing are dehydrated to a residual moisture content prior to being further treated, coal dust and, as a binder, quick lime are then admixed to the sludges, the sludges subsequently are granulated and the granulate thus formed is supplied to the meltdown gasifying zone while increasing the basicity of the slag to a maximum of 1.25.

Title: A repertoire of mappings for a cryptosystem
Inventor: LIU ZUNQUAN
IPC: G09C1/00
Filed: 1994-03-16
Granted: 2005-09-20
Abstract: A cryptographic device and method provide a repertoire of mappings and associated inverse mappings between plaintext and cipher-text vectors. The plaintext (200) is partitioned block-by-block, the block size being userselectable such as N characters. Each mappings maps between a pair of N-dimensional plaintext (200) and ciphertext vectors (280). The mapping or associated inverse mappings is implemented by a matrix with N × N matrix elements, where each element is allowed to take on a range of L values. By permuting the matrix elements within their range, the repertoire has a size = L exp (N × N). A secret key shaved between the users includes information about the selected mapping or associated inverse mapping and may include values N and L. In the preferred embodiment, a pseudo-random vector (247) that varies block-by-block is added as another component to the ciphertext vector (280).

Title: Channel sharing in a mixed macro/micro cellular system
Inventor: BRODIE IAIN RICHARD
IPC: H04W16/32
Filed: 1994-12-02
Granted: 2000-04-04
Abstract: A cellular radio system includes three neighbouring cells (A3, A2, A1) which each have a number of channels (1 to 13, 14 to 26, 27 to 39, respectively) allocated for their use. A microcell M contained within cell (A1) is served by a separate base station. The microcell has available to it channels (1 to 16 and 21 to 26) from the allocations of neighbouring cells (A2 and A3). The base stations (A2, A3 and M) are controlled such that no channel is in use simultaneously in both the microcell (M) and cell (A2 or A3). This arrangement allows channels to be reallocated between neighbouring cells according to demand, without reducing the peak capacity in individual cells.

Abstract: A grafted polyolefin containing one or more of N-vinylimidazole, 4vinylpyridine, or other ethylenically-unsaturated nitrogen-containing or oxygen-containing graftable monomers grafted to a polyolefin backbone is disclosed. The grafted polyolefin preferably has a weight average molecular weight of from about 20.000 to about 500.000, a polydispersity of less than about 10, and an ADT value of at least about 8. The grafted polyolefin can be defined as containing more than about 1.2 % by weight of grafted monomer on a polyolefin, or as containing at least about 13 moles of graftable monomers per mole of polyolefin, or as having an asphaltene dispersancy test (ADT) value of at least about 8. Also described is a lubricating oil comprising a lubricant base oil and a grafted polyolefin as described above. Also described is a method of making a dispersant viscosity index improver. N-vinyl-imidazole or other ethylenically unsaturated nitrogen-containing and/or oxygen-containing graftable monomers and a graftable polyolefin are reacted with enough of an initiator to graft the monomer to the polyolefin. The initiator and/or graftable monomer is added to the other ingredients, maintained at the reaction temperature, over a period of time. The reaction temperature is maintained at a level high enough to give acceptable reaction times. The Nvinylimidazole and the initiator each can be added at a uniform, relatively slow rate during the reaction.

Abstract: A compressor housing and method of manufacture and assembly are disclosed.  The compressor housing includes a cylinder block and a front housing.  An annular projection is formed on the front end of the cylinder block. An annular groove is formed on the rear end of the front housing.  The cylinder block and the front housing are secured to each other to prevent the front housing from being displaced in relation to the cylinder block by engaging the annular projection with the annular groove.  A gasket is located between the front end of the cylinder block and the rear end of the front housing secured to each other to seal between the cylinder block and the front housing.  This compressor and its method of manufacture reduce the amount of misalignment between a shaft bore in the cylinder block and a shaft bore in the front housing, which improves the performance of the compressor.

Abstract: A method and device are provided for controlling an activity mode of a mobile station after the system has originated or terminated a transaction with the mobile station. The activity mode corresponds to whether the mobile station stays "awake" or goes into a sleep mode, which must be made known to the system. If the mobile station does not immediately go to the sleep mode, the base station can expect the mobile station to be reading all slots. If the mobile station is in the sleep mode, the mobile station only reads its assigned paging slots. The mobile station may not go to the sleep mode until a selected amount of activity time has expired; during the activity time, the mobile station continues to read all slots. As a result, the mobile station can immediately receive packets, thereby saving set-up time which increases the response time of the mobile station.
