Abstract: A tubular element (1) adapted for use downhole in drilling and oil & gas prospecting comprises a metallic mandrel (6) adapted to be connected (2,3) within a string of elongate elements, with a GRP(GFK) composite material (7) upon an outer surface of the mandrel in which a plurality of ceramic particles are partially embedded to present exposed contact surfaces in the formed composite material. The surface can be ribbed (4) with flow channels (5) therebetween. Suitable particles are of zirconium oxide, silicon nitride, cubic boron nitride, and mixtures of two or more thereof, whereby improvements in weight/strength ratio, fatigue endurance, increased torsional properties, with reduction of wear on the casing are obtained when such composite tubulars of the invention are used as drill pipe or work string sub-assembly elements.

Abstract: A water supply system for supplying water to a building including a water tank (13) for collecting water from the roof (10) and gutters (12) of the building (11); a water level sensor means (21) for sensing the level of water in the water tank; a tank water system (22) for supplying water from the water tank (13); a water pump (23) for pumping water from the water tank (13) along the tank water system (22); a non-return valve (25) downstream of the pump in the tank water system; a pressure sensor means (26) for sensing water pressure of water within the tank water system, said pressure sensor means (26) is located downstream of the non-return valve (25); a mains water system for supplying mains water; a three port valve (35) having a first port (34) connected to the tank water system downstream from the pressure sensor means (26), a second port (37) connected to the mains water system and a third port (41) connected to the building's water reticulation system; wherein when the first (34) and third port (41) a

Abstract: A method of processing textile material is disclosed in which the material (13) is passed along a predetermined path through a liquid jet device (50, 70, 80, 90, 100, 120, 130) applying a force to the material (13) transversely to the axis of the material (13). High pressure water is used to form one or more belts (11, 12) for applying twist to a yarn (13), sliver or roving (273), or as a jet to intermingle one or more yarns (13). The water may serve to cool the yarn (13) after beating in a false twist process.

Abstract: A method and apparatus are disclosed for fabrication of textiles. The method includes the step of passing a yarn or product along a path through a device. The method also includes applying a rotation force to the yarn or product with at least one jet of liquid directed by the device.

Abstract: A telecommunications service node includes a multi-level architecture comprising an operating system layer interfaced using a compile time linked interface to a service framework layer, and a service application layer interfaced using an object oriented, run time linked interface to the service framework layer. Run time linking of the service applications supports the introduction or modification of service applications during run time execution of the service node. Each service application inherits from the same base class, and is defined by certain criteria which need to be met in order to execute the service. A trader maintains a reference to each available service application. When a certain service needs to be performed, a set of criteria for that certain service are evaluated by the trader, and a particular one of the service applications within the service layer defined to meet the criteria set is selected. The selected service application is then invoked to support the certain service.

Abstract: An automatic activation of a roamer mobile station is implemented in a visited network home location register. Responsive to a registration attempt by the roamer mobile station a default subscriber profile is defined, and a temporary subscriber (directory) number is assigned. Arrangements are also made to insure subscriber payment for any network provided wireless telephone services. Following activation of the roamer mobile station, the default subscriber profile is downloaded for use in providing service. A timer is also started and thereafter monitored for expiration. If the timer expires before the occurrence of a wireless telephone service traffic event involving the roamer mobile station, automatic deactivation of the roamer in the home location register is implemented. In this regard, the default subscriber profile is deleted and the temporary subscriber (directory) number is returned. The billing account for any network provided wireless telephone services is also closed.

Abstract: A bulked multifilament yarn having filaments of polymeric material has alternating points of maximum polymeric density and minimum polymeric density occurring along the length of each filament with a maximum spacing of 10 meters. The yarn may have a crimped structure in which the crimps are of undulating form with more than 50% of the filaments having maximum amplitudes of undulation less than the diameter of the yarn and more than 50% of each filament lies on one side of a diametral plane of the yarn particular to that filament. A process of producing the yarn includes the steps of jet bulking yarn and projecting it against one end of an elongated package during which the pressure prevailing at said one end of the package fluctuates. The pressure varies between a maximum value and a minimum value with a frequency related to the rate of feed of the yarn.

Abstract: Apparatus for producing bulked multifilament yarn incorporates a high pressure fluid passage debouching into an intermediate pressure expansion chamber. The high pressure fluid passage is formed with entries for yarn and high pressure fluid and the intermediate expansion chamber is formed with a yarn-deflecting surface and yarn-discharge passage both located across the chamber from the point where the high pressure fluid passage enters the chamber.

Abstract: Bulked and crimped yarn is produced by a process comprising driving heated yarn forward to form an elongated package of compressed yarn, to which yarn is continually added at one end and withdrawn from the other end. The magnitude of the deviation of the position of the take-off end from a predetermined position is measured and used as a control parameter to control the temperature of the heated yarn.

Abstract: Bulked and crimped yarn is produced by a device comprising yarn feed means arranged to form a yarn package, means for taking off yarn from an end of the package and heat exchanging means arranged to be in heat-exchanging relation with the yarn on its way to the package. Means capable of sensing the position of the take-off end of the package is arranged to send a control signal controlling operation of the heat exchanging means. The yarn feed means may be a fluid jet or feed nip rollers. A stuffer tube or a movable surface may be provided to receive the yarn package. The take-off position sensing means may be optical, electrical, acoustical, pneumatic, or mechanical.
