The hydrostatic fluid bearing comprises a cylindrical stator having orifices for introducing a fluid under pressure, on its inside surface the stator has a split ring constituted by an assembly comprising a plane metal plate and a layer of self-lubricating composite material. The layer of composite material has cells for surrounding orifices for introducing fluid under pressure, once the assembly has been put into place inside the stator.

An electric power tool has a motor-driven circular tool that can be clamped by means of a clamping device. A mechanical braking device (2) serves to brake the tool. A safety element (4) prevents improper handling of the electric power tool. In a safety position, the safety element (4) prevents the motor from being turned on and activates the braking device (2). In a release position, the safety element (4) allows the motor to be turned on and the braking device (12) is released. An additional locking mechanism prevents that a clamping lever, needed to actuate the clamping device, can be actuated in the clamped state in the safety position. In the release position of the safety element, the locking mechanism is unlocked.

A valve for controlling a fluid, in particular for controlling a gas. The valve includes a valve housing which accommodates an electromagnetic actuating unit for a solenoid armature which is guided axially displaceably in the valve housing and which cooperates with a valve seat via a valve-closing member, so that a fluid stream from an inflow side to an outflow side of the valve is controllable. At least one lubricant chamber adjacent to the guide gap between the valve housing and the solenoid armature is provided.

A partially assembled grill comprises a frame unit having a bottom and two sides, one side mounted to pivot on one end of the bottom so that it is folded against the bottom, and the other side mounted to pivot on the other end of the bottom and positioned generally perpendicular to the bottom, to form a partially folded frame, and a grill casing, wherein the partially folded frame unit encloses the grill casing on two adjacent perpendicular surfaces.

The invention relates to an electrical clip connector for an electrical connection of a cable (20) to an electrical mating connector, in particular to an electrical connection device of a controller for an electric motor of a cooling fan, wherein the clip connector (100) has a holder section (110) and a fastening section (120), and at least one electrical line (200) of the cable (20) can be provided in the holder section (110) in such a way that an electrical contact device (210) of the line (200) projects freely from said holder section, and the clip connector (1) can be fitted to the connection device by means of the fastening section (120). The invention also relates to an electrical clip connection having an electrical clip connector (100) and an electrical mating connector, in particular an electrical connection device of an electrical / electronic device, wherein an electrical contact device (210), in particular a flat plug sleeve (210) or a socket contact, of the clip connector (100) can be accommodated and is accommodated in the mating connector by way of a circumferential section in at least two steps in a successively more interlocking manner when the clip connection comprising the clip connector (100) and the mating connector is established. The invention also relates to a ready-to-use electrical cable (20), in particular for electrically connecting a controller (3) to an electric motor (2) of a cooling fan, having an electrical clip connector (100) according to the invention.

A system and method for continually updating a large and substantially continually changing dataset that is accessed by multiple application threads, such as a group identity database of members in communication groups of wireless communication devices. A first server holds the group identity database and, as application threads on the first server access the database to set up group communications, a second server sends new group identity data to update the database, with the new data arriving as discrete, ordered blocks. A first server-resident data-index table is updated with the ordering information of the new data blocks, and a first server-resident checkpointing thread places the ordering information of the new data blocks into a checkpoint cache and checkpoints the ordering information as the new data blocks are updated into the group identity database and verifies the ordering (or version) of the data as against the data-index table.

A lance for injecting a solid material into a vessel, such as a direct smelting vessel for producing molten iron, has a core tube assembly comprising a passageway for solid material. The core tube assembly has an inlet for receiving solid material at a rear end and an outlet for discharging material at a forward end. The core tube assembly comprises an outer tube of a structural material and an inner tube of a wear resistant material that are bonded together. A method of manufacturing the core tube assembly may include spin casting the outer tube of the structural material; spin casting the inner tube of the wear resistant material onto the inner surface of the outer tube; and metallurgically bonding the tubes together.

A threaded coupling for a drill string component includes a body on which is formed a thread.

A method of joining a metal-ceramic substrate having metallization on at least one side to a metal body by using metal alloy is disclosed. The metal body has a thickness of less than 1.0 mm and the metal alloy contains aluminum and has a liquidus temperature of greater than 450° C. The resulting metal-ceramic module provides a strong bond between the metal body and the ceramic substrate. The resulting module is useful as a circuit carrier in electronic appliances, with the metal body preferably functioning as a cooling body.

A shroud lock for locking a position of a needle shroud relative to a housing of an autoinjector, includes a shroud beam arranged on the needle shroud and biased radially outwards, a stop arranged within the housing, a recess arranged proximal of the stop, and a cap coupled to the housing and adapted to prevent distal translation of the needle shroud relative to the housing. At least a portion of the shroud beam is within the recess when the cap is in place and, the shroud beam abuts the stop after the needle shroud is locked relative to the housing of the autoinjector. The disclosure further relates to an autoinjector and to a method for assembling such an autoinjector.
