Abstract: A locking device is disclosed for preventing rotation of one component relative to another component to which it is connected. The locking device comprises a locking plate having a component engaging portion to engage one component, A surface of the locking plate is grooved to engage with a grooved surface carried by the other component. One or more fixing holes are provided for one or more fixing members to be passed through, to force the grooved surface of the locking plate into engagement with the grooved surface carried by the other component.

Abstract: The invention relates to a pipe connector for a pressure-resistant, positive-fit, high pressure screwed joint. The connection includes a formed tube; a screw body or connector branch with a cone, which connects to a parallel axis drilling, with a radial end surface; a union nut; a sealing ring; and a retaining ring. The formed tube has a parallel axis end-piece with the same tube diameter and which corresponds to the depth of the tube seat base. The formed tube has a pronounced head which forms a mating face, with a cone surface of the union nut, and which leads to an abutment face at a front face of the retaining ring, essentially aligned with the tube axis. The retaining ring has a radial ring surface, which, in the assembled state, contacts with the front face of the cone of the connector branch or screw body, and thus permits a block assembly.

Abstract: A connection system comprising first and second fluid-conducting components, each of which includes a connection face with a fluid port and at least one slot arrangement comprising first and second substantially parallel slots. The slots each include an aperture and first and second tapered surfaces. The system further includes a connector comprising a coupling element with a support and first and second coupling members which extend in substantially parallel relation therefrom, and a slide element moveable between a first, unlocked position in which the connector is movable relative to the fluid-conducting components and a second, locked position in which the slide element engages the fluid-conducting components. The coupling members each include first and second tapered cam surfaces, and first and second cam surfaces.

Abstract: An auto-drain unit for a compressed gas supply system, comprising: a first, main chamber including a liquid collection reservoir; a second, reference chamber; a discharge valve actuatable to discharge collected liquid from the liquid collection reservoir; a trigger mechanism for actuating the discharge valve; a diaphragm at least in part defining the liquid collection reservoir and the reference chamber, the diaphragm being configured to be movable under the weight of liquid collected in the liquid collection reservoir and operate the trigger mechanism when the weight of collected liquid exceeds a predetermined threshold; and a fluid conduit fluidly connecting the reference chamber to a location in the main chamber above the maximum possible liquid level therein.

Abstract: A modular fluid control system, comprising: a control module for receiving parallel electronic control signals as a plurality of data streams, the control module including a control unit configured to convert the data streams of the parallel electronic control signals to serial electronic control signals, each including a plurality of data pulses as control instruction signals, and an electrical connector; a plurality of valve modules, each valve module including at least one valve operable to control the flow of pressurized fluid; and a plurality of manifold modules connectable in series to the control module and connected to respective ones of the valve modules, each manifold module including a fluid supply conduit to provide a common manifold for receiving pressurized fluid, first and second electrical connectors for connection with ones of the connectors of adjacent manifold modules and the connector of the control module to provide an electrical bus for transmission of the serial control signals and powe
