Granted: 2006-07-04
Abstract: A flexible armoured pipe, which comprises an inner liner, which is surrounded by a pressure armour, is built up by the joining together of profiles, which have a number of recesses. According to the invention, the profiles are configured as K-profiles (10, 16, 17), which have recesses (10a, 10b, 10c, 10d), which are arranged in adjoining surfaces of the profile. When the profiles are brought together, the recesses form a cavity in which a locking element (12, 14, 18) can be inserted, the function of which is to prevent displacement of the K-profiles at right-angles to the axial direction of the pipe when this is exposed to axial, compressive forces. The locking element can be I- shaped (14), be circular or be configured as a wire (18) with a C-shaped cross-section. The locking element can also be made either o f a rigid or an elastic, deformable material. With a C-shaped locking element, the whole of the cavity, which is formed by the recesses, is not filled out. A channel is hereby formed through which undesired fluids can be led away or through which cleaning fluids can be introduced.

Abstract: A plasma arc torch (10) has a secondary gas flow (46) that is extremely large during piercing of a workpiece (36). The secondary flow (46) exits the torch immediately adjacent the transferred plasma arc (34) and is an extremely uniform, swirling flow. A swirl ring (60) is located in the secondary gas flow path (50) at the exit point. A prechamber (58) feeds gas to the swirl ring (60), which is in turn fed through a flow restricting orifice (56). For certain applications the secondary gas (46) is a mixture of an oxidizing gas and a non-oxidizing gas in a flow ratio of oxydizing to non-oxidizing in the range of 2:3 to 9:1. A network (44) of conduits and solenoid valves (SV1-SV17) operated under the control of a central microprocessor (90) regulates the flows of plasma gas (42) and secondary gas (46) and mixes the secondary gas (46). The network (44) includes valued parallel branches (78,80,84,86) that provide a quick charge capability and a set of venting valves.(SV11-SV14), also electrically actuated by the microprocessor (90), to provide a quick discharge. In a preferred high-definition embodiment, a nozzle (28) with a cut back outer surface and a large, conical head (28b) allows a metal seal and enhanced cooling.

Abstract: The present invention provides a method and apparatus for transmitting NRZ data signals across an interface comprising an isolation barrier disposed between two devices interconnected via a bus. The apparatus comprises a signal differentiator for receiving an NRZ data signal and outputting a differentiated signal. A driver comprising a tristate gate has as a first input the data signal and as a second input the differentiated signal for enabling the tri-state gate when the differentiated signal is high. A bias voltage is applied to an output of the tri-state gate to derive as output a transmission signal for transmission via the bus across the interface between the two devices. In this way, the transmission signal output from the first device comprises an intermediate transmission signal corresponding to the bias voltage when the tri-state gate is disabled, a high transmission signal when the tri-state gate is enabled and the first input to the tri-state gate is high, and a low transmission signal when the tri-state gate is enabled and the first input to the tri-state gate is low. A Schmidt trigger is provided as a receiver in the second device for receiving as input the transmission signal and outputting a reconstituted data signal corresponding to the synchronized data signal.
