Abstract: Genetic procedure for the allocation of calls issued via the landing call devices of elevators comprised in a multi-deck elevator group, in which procedure a multi-deck elevator model is formed in which the limitations of and rules of behaviour for each elevator in the multi-deck elevator group and each car of each elevator are defined; a plurality of allocation options, or chromosomes are formed, each of which contains a car data item and an elevator direction data item for each active landing call, and these data, or genes, together define a car to serve each landing call as well as a collective control direction for the elevator; for each chromosome, a fitness function value is determined; one or more of the chromosomes are selected and altered in respect of at least one gene to form one or more new chromosomes; fitness function values are determined for the new chromosomes; the process of altering the chromosomes, selecting chromosomes and determining fitness functions is continued until a termination criterion is met and, based on the fitness function values, the most suitable chromosome is selected and the calls are allocated to the elevators and cars in the elevator group in accordance with this solution.

Abstract: A terrestrial repeater is disclosed for use in a satellite transmission syst em that may also include a plurality of satellites. The terrestrial repeaters are implemented as OFDM transmitters to minimize the channel impairments caused by multi-pa th propagation. The OFDM terrestrial repeaters differentially encode the transmitted signal over frequency, as opposed to time, in order to avoid channel phase distortion. The OFDM receiver allocates two unmodulated sub-carriers as pilot bins and there by provides two sub-carriers as a reference within each OFDM symbol. At the OFD M receiver, the two unmodulated pilot bins contain no phase information and provide a reference for the differential demodulation performed by the OFDM receiver. The OFDM transmitter operates in two modes, namely, a normal mode and a transmitter identifier information (TII) mode. The TII mode contains all of the function s of the normal mode, and also transmits a repeater identification signal with the customer data, using the inactive OFDM sub-carriers (bins). In a normal mode, the OFDM transmitter optionally fills unused (inactive) sub-carriers with zeroes and in a TII mod e, the OFDM transmitter uses at least some of the unused (inactive) sub-carriers to transmit the transmitter identifier information (TII). The predefined TII value is mapped onto a set of complex symbols. The TII signal facilitates the receiver test equipment in associating the received signal with the terrestrial repeater(s) that generate the TII signa l.

Abstract: L'invention concerne des lubrifiants synthétiques de première qualité contenant une huile de base synthétique isoparaffanique d'hydrocarbure et une quantité efficace d'au moins un, et généralement de plusieurs additifs lubrifiants tels qu'un détergent, un agent dispersant, un antioxydant, un additif anti-usure, un améliorant du point d'écoulement, un améliorant de l'indice de viscosité et analogue. Un procédé d'hydroisomérisation de la charge et de déparaffinage de l'isomérat permet de faire dériver l'huile de base d'une fraction de charge paraffineuse, paraffinique, d'hydrocarbure obtenue par synthèse Fischer-Tropsch. Le point d'ébullition initial de ladite fraction varie entre environ 650-750  DEG F et peut continuer à augmenter jusqu'à 1050  DEG F au moins. La différence de température T90-T10 de la charge paraffineuse est d'au moins 350  DEG F et son hydroisomérisation est effectuée, de préférence, sans aucun prétraitement, autre que le fractionnement optimal. Le lubrifiant peut également contenir des matières du type hydrocarbure et d'huiles synthétiques de base. Le comportement des lubrifiants, tels que les huiles complètement formulées multigrades pour carter d'automobile et de transmission, obtenues par addition d'un ensemble additif approprié à l'huile de base isoparaffanique est supérieure à celle des huiles similaires complètement formulées à base de polyalphaoléfine (PAO) et d'huiles de base classiques dérivées du pétrole.

Abstract: En vue d'améliorer le fonctionnement on combine le codage de voie avec les principes du codage spatio-temporel. Avec K unités terminales synchronisées émettant sur des antennes N vers une station de base comprenant un nombre d'antennes de réception M  DOLLAR m(G K), on augmente la capacité du système et on améliore le fonctionnement au moyen d'un schéma de codage concaténé dans lequel le code interne est un code de bloc spatio-temporel et le code externe est un code de correction d'erreur de voie classique. Les symboles de données sont d'abord codés à l'aide d'un code de voie classique, puis les signaux résultants sont codés à l'aide d'un code de bloc spatio-temporel. Au niveau du récepteur, le code de bloc spatio-temporel interne est utilisé pour supprimer les interférences provenant des autres terminaux situés sur la même voie et des décisions pondérées sont prises au sujet des symboles transmis. Le décodage de voie qui suit produit les décisions fermes relatives aux symboles transmis. On obtient ainsi une cadence de transmission des données accrue du fait qu'on divise efficacement le débit binaire entrant en plusieurs voies, chaque voie étant transmise sur son propre terminal.

Abstract: The present invention deals with the problem with packet based services consuming considerable bandwidth over links with shortage of bandwidth. The object of the present invention is to reduce the amount of information when transferring a signalling message and thus save bandwidth. After receiving a signalling message in a first node the signalling message is identified. The signalling message is replaced by an indicator, under usage of information from the identification, which indicator is transferred to a second node. The second node restores the signalling message using the indicator.

Abstract: There is disclosed an improved pump (5, 5') particularly suitable for use in a method of "artificial lift" in an oil/gas well. Known pumps used in artificial lift methods suffer from a number of problems/disadvantages - e.g. low efficiency (hydraulic efficiency). The disclosed embodiments of the invention provide a pump (5, 5') which provides a positive displacement of a predetermined volume of well production fluid for each operative cycle of the pump - in contra-distinction known to pumps which provide axial flow of well production fluid. The inventive pump (5, 5') provides a chamber (10, 10') having a volume (V, V'), an inlet (15) to the chamber (10, 10'), an outlet (20) from the chamber (10, 10'), and means for varying the volume (V, V') of the chamber (10, 10'). The means for varying the volume (V, V') of the chamber (10, 10') is controlled by relative rotation of first and second bodies (30, 35; 30', 35').

Granted: 2006-07-04
Abstract: Rock bits comprising wear and fracture resistant surface of this invention include a steel bit body having at least one leg extending therefrom. A steel cone is rotatably disposed on the leg. The steel cone includes a plurality of steel cutting elements that each projecting outwardly a distance therefrom.      At least a portion of the cone comprises a wear resistant surface formed from a wear resistant composite material. The wear resistant composite material is made by the process of combining powders selected from the group consisting of carbides, borides, nitrides, carbonitrides, refractory metals, cermets, Co, Fe, Ni, steel, and combinations thereof, to form a material mixture. The material mixture is applied onto a designated surface of the cone, in one form or another, when the cone is in a pre-existing rigid state. Depending on the particular application, the material mixture can be applied in as a slurry to the designated surface of the cone to form a coating thereon. Alternatively, the material mixture can be preformed into a green part that is configured to be placed over the designated surface prior to being disposed thereon. The material mixture is then pressurized under conditions of elevated temperature to form the wear resistant surface. In the event that the material mixture is preformed into a green part, the preformed green part can be sintered prior to its placement on the designated cone surface.      The sintered part can then be attached to the cone surface by brazing process.
