A system for a pneumatically-actuated engine throttle of a snubber ram unit of an oil service/drilling rig, to stop accidental engine engagement of a pipe section and its being pulled into or pushed through the snubber ram unit of the rig, the system comprising a switch positioned in an air line between a pneumatic throttle control and an engine throttle of the rig, the switch manually actuatable ...

The invention relates to a method of arranging communication in a local area networking system comprising a first device, a second device and an intermediate node for arranging data transmission between the first device and the second device. The second device is arranged to multicast and/or broadcast messages to devices in the system. The transmission of multicast and/or broadcast messages to the...

A power unit in a hybrid vehicle consists of two combustion engines (1,2) which drive a generator (6) via automatic clutches (3,4) and a gear system (5) . The energy of the generator can be transmitted either to the wheel engines or to a battery unit according to choice. The power unit and the battery unit are housed in pull-out cassettes (8,14). The cassette (8) of the power unit can be used as a...

The invention relates to a process for manufacturing a particulate titanium dioxide product, wherein hydrated titanium dioxide is precipitated from an aqueous solution of titanium oxychloride by adding to the solution titanium dioxide particles as crystal nuclei and the product obtained from the precipitation step is isolated and optionally calcined. The process is characterized by the addition of...

A control system basing on the use of gestures and functioning especially in mobile terminals. The gesture control system is provided with a general purpose interface ( 320 ) with its commands for applications ( 310 ) to be controlled. The processing software ( 330 ) of the gesture signals includes a training program ( 331 ), trained free-form gestures made by the user being stored in the gesture ...

Fixing a cylindrical tube (3) passing through a bore (5) in a spherical wall (4) of a nuclear pressurized water reactor cover comprises machining an annular recess (7) in the inner surface of the cover round the bore and filling it with two layers of metal (8, 12) to which the tube is welded. The metal layers are deposited by an automatic welding torch (20) with a continuous metal feed (23) and fu...

Additional metal deposition is performed automatically by a welding torch (20) fitted with metal fusion (20') and additional metal supply (21) units. The torch is rotated about an axis (9) aligned in a radial direction relative to the concave surface of the spherical wall of a nuclear pressurized water reactor cover and located at the center of a machined annular recess (7). The rotating torch is ...

The arrangement (2) is for dismantling or fitting a work tool from or on a vehicle (1) and has a platform (4) on which the work tool is fitted and is slidably connected with other parts of the arrangement. The arrangement or the tool incorporates support feet (3). - The arrangement incorporates a fork construction (5), which has at least two arms (6) with which the platform is slidably connected a...
