A processing method for a workpiece includes a cutting step of cutting the workpiece along streets by a cutting blade having a V-shaped tip end, to form V grooves of which shallower parts are wider than deeper parts, and a cleaning step of cleaning a back surface of the workpiece with cleaning water, after the cutting step is carried out.

A wing-box structure for an aircraft is disclosed having an upper cover, a lower cover, longitudinal forward and rearward spars, and a plurality of transverse ribs. One of the transverse ribs is retained by a pair of opposed captive features disposed on an interior side of either the forward and rearward spars or the upper and lower covers. The rib is bonded rib to the forward and rearward spars and/or the upper and lower covers at a location where the rib is retained.

Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes causing provision of negative pressure, via a flow path, to a wound dressing configured to be positioned over a wound, the flow path configured to fluidically connect the pump system to the wound dressing, measuring a first pressure value in the flow path at a first time, measuring a second pressure value in the flow path at a second time, calculating a first rate of pressure change using the first and second pressure values, and in response to determining that the calculated first rate of pressure change satisfies a threshold rate of change, providing an indication that the wound dressing is full, wherein the method is performed under control of a controller of the pump system.

A device for assembling plastic objects including caps for coupling to base support at least partially counter-shaped to the cap. The device includes at least part of an assembly line defining assembly path and assembly plane including the assembly path and plurality of spindles moveable along the assembly path by an apparatus and configured to controlledly pick up the caps, the spindles position and push the caps onto the base supports along the assembly path; positioning apparatus including first and second detectors, controller with auxiliary control system to translate and rotate spindles along directions perpendicular to assembly path and plane and third encoder to detect spindle orientation relative to assembly path. First detector to detect first orientation, second detector to detect second orientation and controller to detect first orientation and second orientation by detectors and operate auxiliary control system to align base support and cap.

A method of making a wind turbine blade is described. The blade comprises first (12) and second (14) half shells bonded together and a shear web (16) bonded inside the shells. Prior to joining the shells together, the shear web is positioned in one of the shells. A plurality of bars (70) are attached to the shear web and engaged with a plurality of mounts (80) in order to support and stabilise the shear web relative to that shell. The shells are then arranged one above the other whilst the bars remain attached to the shear web. The bars continue to support the shear web whilst the shear web is aligned with the other shell. The bars are then detached from the shear web and the shells are brought together to bond the shells to each other and to bond the shear web between the shells.

A molded resin product includes a design layer including a decorative layer having a first color, a shielding layer having a second color different from the first color, and a resin base layer. A cover layer formed of a polymer film is disposed close to one end of the design layer. Part of the decorative layer exposed from the shielding layer serves as an exposed region. The exposed region and part of the shielding layer constitute a pattern portion presenting a predetermined figure or character when viewed in plan through the cover layer. The rest of the shielding layer constitutes a base portion. The layer thickness of the base portion is set smaller than the layer thickness of the pattern portion in a region thereof where the shielding layer is formed.

A method of assembling a member and a cap of a vane using a tool which allows the application of a pressing force of the cap against the member during a step of polymerisation by heating a resin for bonding these components. To this end, the tool includes an inflatable bladder and a pocket which surrounds the bladder and the vane so that the inflated bladder applies the pressing force. The heating can be carried out by resistors which are mounted in the bladder and/or using a device for supplying external heat.

A drive system for driving an automatic welding machine for joining the edges of sealing sheets, comprising pressing/advancing rollers located vertically opposite one another and driven by a shared drive motor, downstream of which a transmission gear mechanism is connected, and an upper pressing/advancing roller is disposed rotatably about a roller rotational axis on a tensioning arm of the automatic welding machine, which is pivotable about a tensioning arm axis, and a lower pressing/advancing roller is disposed rotatably about a roller rotational axis on a frame of the automatic welding machine, which is supported by at least two drive rollers, wherein the drive motor and the transmission gear mechanism are rigidly attached to the frame, and the drive motor comprises a motor armature including a protruding rotational shaft, and the transmission gear mechanism comprises a rotatable protruding input shaft and output shaft.
