A laser processing system includes a first positioning system for imparting first relative movement of a beam path along a beam trajectory with respect to a workpiece, a processor for determining a second relative movement of the beam path along a plurality of dither rows, a second positioning system for imparting the second relative movement, and a laser source for emitting laser beam pulses. The system may compensate for changes in processing velocity to maintain dither rows at a predetermined angle. For example, the dither rows may remain perpendicular to the beam trajectory regardless of processing velocity. The processing velocity may be adjusted to process for an integral number of dither rows to complete a trench. A number of dither points in each row may be selected based on a width of the trench. Fluence may be normalized by adjusting for changes to processing velocity and trench width.

The invention relates to an air freight transport system which is used to transport various freights to different destinations (26, 28, 30). According to the invention, a transport aeroplane (10), which crosses through at least three air zones (14, 16, 18) associated with one station (20, 22, 24), is prepared. The aeroplane can not land on one of the stations (20, 22, 24). Transportation of the freight between the transport aeroplane (10) and one of the stations (20, 22, 24) occurs with the help of feeder planes (32), whereby transfer of the freight between the feeder plane (32) and the transport plane (10) takes place in the air. The transport plane (10) and two feeder planes (32) form the inventive air freight transport system and the transport aeroplane (10) can comprise two feeder planes (32) which are connected together. The inventive air freight transport method improves the charge of the transport aeroplanes (10). Additionally, the transport paths for individual freights can be shortened thus making said method more economical.

A trocar having a blade split into two portions, a fixed portion and a movable portion. The movable portion is attached to the fixed portion at a pivot point that allows the movable blade portion to extend beyond the width of the fixed portion or be retracted within the width of the fixed portion. The cannula may be slidably received on the blade and provide the means to retract the movable portion of the blade to within the width of the fixed portion of the blade.

The invention relates to a device for applying a glue track (6) to a wrapping strip (1) of a rod-shaped product of the tobacco processing industry. The device is provided with a nozzle (2) which is fixed relative to the wrapping strip (1) in a period of applying the glue track (6). The nozzle is provided with an outlet opening (3) which is aligned with the passing wrapping strip (1). The glue gets out through the outlet opening, wherein a roller (4) which can be rotated and driven through a driving device is arranged between the wrapping strip (1) and the outlet opening (3) of the nozzle (2). The glue which gets out of the outlet opening (3) is applied to the roller. Furthermore the roller directly applies the glue to the wrapping strip (1), wherein the rotation direction of the roller (4) is set so that the motion of the roller (4) is opposite to the motion of the wrapping strip (1) on the side surface which faces the passing wrapping strip (1).

Overhead truss assemblies for use with retail displays are provided. The assemblies include multiple trusses that are parallel to and spaced from each other, spanning overhead or otherwise elevated and connecting merchandise display racks on opposing sides of an aisle or aligned with and atop a single merchandise display rack.
