摘要:
A method for placing at least one duct/communication cable below a road surface in an area. The area comprises a first layer and a second layer, the first layer being a road layer, such as asphalt or concrete, and the second layer being a bearing layer for the first layer and being located below the first layer. The method comprising the steps of cutting a micro trench in the area through the first layer into the second layer, placing at least one duct/communication cable in the micro trench so that that duct/communication cable is placed below the first layer, and filling the micro trench so as to restore the road surface.

Woodworking machines and safety methods for use with those machines are disclosed. The machines include a detection system adapted to detect one or more dangerous conditions and a reaction system associated with the detection system. The reaction system can include an explosive to trigger the system, and also can be configured to retract a cutting tool at least partially away from a cutting region upon detection of a dangerous condition by the detection system.

摘要:
A system for cutting blocks of food product into bars of substantially equal weight. The system includes a cutter conveyor configured to receive incoming blocks of food product and move the blocks along an in-line processing path in a plane for cutting; a programmable logic controller coupled to the cutter conveyor; and, multiple stations associated with the cutter conveyor. One such station is a camera vision system configured to create an image of the slab portion, and further including a camera controller coupled to the vision system and the PLC, and configured to determine an optimized cut solution of the slab portion from the image and data related to the food product, and is configured to provide the cut solution to the PLC. The PLC is configured to control the cutting of the food product, based on the optimized cut solution, into bars of substantially equal weight.

Woodworking machines including conductive cutters adapted to cut workpieces, and motors adapted to drive the cutters are disclosed. The machines also include a contact detection system adapted to detect contact between a person and the cutter, and to distinguish contact between the person and the cutter from contact between the workpiece and the cutter. The machines further include a reaction system adapted to cause a predetermined action to take place upon detection of contact between the person and the cutter by the contact detection system.
摘要:
A cutting arrangement for longitudinally cutting material includes two blades disposed across from one another and which cooperate during cutting. Each blade is embodied as a circular blade having a sharp cutting edge and supported by an adjusting or placement mechanism. During the cutting process, the circular blades are positioned by the adjusting or placement mechanisms so that the cutting edges overlap one another to form an overlap zone, the center of which coincides with the middle of the material that is to be cut. An adaptive control assembly includes individual drive motors for driving each blade and enables constant side load force control for each blade, such that side load pressures are adjustable in response to changes in web sped, web tension, and blade condition in real time. Automatic blade diameter sensors calculate the zero point of the cut, determine the appropriate blade speed and automatically set the overlap.

摘要:
In a brush cutter (100), when it is determined based on acceleration information including frequency components, supplied from an acceleration sensor (24) included in the brush cutter (100) that the acceleration shows a peak in a range of frequencies lower than 100 Hz, the flow moves to step S5 to amplify the acceleration peak. In next step S6, the acceleration peak is compared with a threshold. When the result of comparison shows that the acceleration peak is higher than the threshold, the flow moves to step S7 to produce a safety signal. The safety signal is output from the controller (26) to a high voltage generation circuit (30) to stop generation of a high voltage in the high voltage generating circuit (30). In this manner, the acceleration sensor (24) is used to detect any unexpected, sudden danger, while diminishing influence of the acceleration caused by vibration inherent to the own nature of the work apparatus, its intended regular operation and its posture change in regular operation.
