摘要:
A system and method in a wireless communications environment maximizes voice quality in low capacity situations. A Mobile services Switching Centre (MSC) that is associated with a base station of a cell is capable of assigning speech calls of mobile terminals to either a full-rate (FR) or a half-rate (HR) channel. The FR channels provide better transmitted voice quality but consume twice the bandwidth (two time slots versus only one for HR channels). When occupied cell capacity is low, an MSC assigns connections to FR channels. After occupied cell capacity reaches a predetermined threshold value, the MSC assigns connections to HR channels whenever possible. Also, handover procedures can reclaim available capacity by switching a connection from a FR to a HR channel. The superior voice quality of the FR channels are therefore provided to mobile terminal users more often.

In a cellular telecommunications network, geographical restriction is stored for a mobile subscriber in the subscriber's record (100A, 100B, 100C, 100D) in a database at a node of the network, preferably at a home location register [HLR] (24). In accordance with one mode of the invention, the mobile station is permitted to operate only in cells identified in the subscriber's record in the HLR. In accordance with this mode, only applicable cells listed in the subscriber's record are paged when a call is direct to the mobile station, and the mobile station can only originate calls and sustain calls from such cells. In a variation of this mode, calls originated by the mobile station in the applicable cells listed in the subscriber's record can be sustained when the mobile station travels into non-applicable cells. In accordance with another mode known as “soft” restriction, a first (e.g., reduced) tariff is applied to calls originated and received in cells listed in a geographical restriction field of the subscriber's record in the home location register, with calls to and from other cells being permitted at a second (e.g., standard) tariff.

A method and cast wear resistant component made of an alloy that includes carbon, tungsten, chromium, and cobalt with the balance essentially iron and other alloying components made using waste, surplus or worn-out cemented carbide product, such as cemented carbide cutting tool inserts. In one method, the alloy further includes silicon, manganese, nickel, titanium, and molybdenum. In practicing the method, pieces of waste, surplus or worn-out cemented carbide product having tungsten carbide (WC) are added to a cast iron alloy melt. The melt includes enough chromium to control solubility of the WC. In one method, precipitated carbide structure having chromium and carbon is produced with tungsten in the melt being substitutionally dissolved. In one implementation, tungsten is substitutionally dissolved in a lattice of the precipitated carbide structure. Carbide can be added to the melt via super inoculation. The cast wear resistant component can be a cutting tool.

The disclosure relates to a method and an apparatus for forming and thermosealing one end of a packaging container which is manufactured from thermosealing material. The packaging container is placed in a conveyor which brings it into contact with mechanical forming devices (22) which progressively reform the packaging container end so that a sealing fin (6) oriented in the direction of movement of the packaging container is formed. In a subsequent sealing station (12), thermoplastic material located in the sealing fin (6) is heated to sealing temperature, whereafter wall portions included in the sealing fin are mechanically urged against one another during simultaneous cooling and continued advancement.

A method of forming a two-layer plastic pipe (4;8) to be laid in the ground for conducting material therethrough forms a core pipe (2) consisting essentially of a first plastic material and forms a detachable outer hose (3;7) of a second plastic material around said core pipe (2) by a suitable coating method, including in said second plastic material an amount of additives effective to protect said core pipe with said outer hose from stresses and loads of laying said core pipe and outer hose and usage thereof in ground.
摘要:
During combustion of a water-vapor generating sulfur-containing fuel, the pressurized flue gases are cooled, while extracting the main part of the latent heat of evaporation of the water vapor included and while removing sulfur impurities, using a coolant liquid in drop form in a scrubber. After having passed through the scrubber, the flue gases are mixed with a proportion of heated flue gases, which have previously passed through the scrubber, so that the temperature of the flue gases after said mixing exceeds the dew point for sulfuric acid in the flue gases. The flue gases are then heated in a heat exchanger and are thereafter expanded in an expansion machine to atmospheric pressure while reducing their temperature again without falling below the dew point for sulfuric acid.
