A device for a hydraulic cutting tool (30) for cutting of at least one pipe (16, 18, 20) or tubular object beneath a water floor (10), wherein the cutting is carried out from a surface facility (2). The cutting tool (30) is anchored in a pressure tight manner in the pipe (16), whereupon pressurised gas (86) is pumped into a pipe section (80) immediately below the cutting tool (30). With this, liquid (8), and eventually pressurised gas (86), will flow out of the pipe section (80) via a short drain pipe (66) through the cutting tool (30), so as to create a gas filled pipe volume (90) comprising the relevant cutting depth (32) in the pipe section (80). The invention differs from prior art by the outflowing liquid being led onwards up to the surface facility (2) via a drain line (92). The upper end portion of the drain line (92) is connected to at least one adjustable choke device (102, 104). This allows the gas overpressure in said pipe volume (90) to be controlled during the cutting, providing optimal operating conditions during the hydraulic cutting.

A handheld food slicer including a first handle having a plurality of elongated fingers, each finger separated from an adjacent finger by a blade receiving slot, a second handle movably coupled to the first handle and a plurality of blade members spaced to align with the blade receiving slots to mate with the fingers to collectively define a food receiving passageway when the first and the second handles are in an expanded configuration in which a distal end of the first handle is at least partially spaced apart from a distal end of the second handle, the fingers of the first handle configured to pass through the food receiving passageway adjacent the blade members as the first and the second handles move from the expanded configuration towards a compressed configuration in which the distal end of each of the first and the second handles is relatively closer to the other.

An improved blade for use with an oscillating power tool is disclosed. A rectangular style blade includes side teeth to eject debris and allow rapid but well controlled blind plunge cuts. The side teeth are preferably asymmetric with a forward orientation to bias debris out and the blade inward. Preferably one or more openings or slots allow for additional debris removal. The side teeth also allow for controlled side cutting.

The invention provides an automatic cutting and turning method and device special for coiling a conical wrapper of croissant. The automatic cutting and turning method is characterized in that during parallel moving, strip-type wrappers are cut and are transversely cut into a plurality of conical wrappers by a cutter die; a plurality of transverse wrappers are turned to be straight wrappers; and therefore, stuffing is subsequently added into the wrappers or no stuffing is added into the wrappers to form the croissant.

The invention relates to a super-deep underground continuous wall which comprises an underground continuous wall body. Guide walls are symmetrically arranged on the two sides of the wall body, the cross sections of the guide walls are in the shape of an L, the lower ends of the guide walls are located on underground rock-soil, and the lug edges of the guide walls are connected with a concrete pavement. The invention further discloses a construction method of the super-deep underground continuous wall. The method includes the following steps of construction preparation, measuring, guide wall manufacturing, wall protection slurry manufacturing, grooving construction, bottom-clearing replacement, connector cleaning through wall brushing and unit slot section inspection, wherein a grabbing-milling integrated grooving method is used in the grooving construction. The method is high in grooving efficiency, short in construction time and short in groove wall soaking time, the grabbing-milling integrated grooving method is used in the grooving construction, technologies can be changed timely according to different stratum hardness situations, the characteristics that a grab bucket is high in digging speed at the soft soil layer and milling wheel can achieve rapid milling and digging footage at a hard soil layer or bed rod with standard penetration test blow count exceeding 45 are fully used, and therefore rapid and efficient grooving of the whole wall can be achieved.

The subject invention provides a portable saw table assembly for cutting a material longitudinally, laterally, and at various angles thereto. The assembly includes a first and a second table rail being parallel and spaced from each other and each extending between a proximal end and a distal end. A saw rail is moveably supported by the first and the second table rails for moving longitudinally along the table rails between the proximal and the distal ends and a mounting plate is moveably supported by the saw rails to allow movement of the mounting plate laterally along the saw rail between the first table rail and the second table rail. A saw plate is rotateably supported by the mounting plate for carrying a saw to cut the material. A guide bar is disposed diagonally relative to the first and the second table rails and engages the saw plate to guide the saw plate diagonally in response to simultaneous movement of the saw rail longitudinally and the mounting plate laterally.

The invention relates to a plastic recycling device with a compression structure for processing plastic shells, which includes a top plate, an annular sleeve, a workbench and a base. A pillar is fixed on the bottom of the top plate, and a servo motor is installed on the left side of the right pillar. The left side of the servo motor is provided with a connecting shaft, and the left side of the connecting shaft is provided with a first gear, the left side of the first gear is provided with a second gear, and the inner side of the second gear is provided with a screw, the The top of the screw rod is equipped with a bearing, and the top end of the bearing is provided with a top plate, and the bottom end of the screw rod is provided with a lifting column. The beneficial effect of the present invention is that: the hydraulic telescopic rod can make the movable rod inserted inside the lifting column descend downward, and the cutting piece can also cut downward to cut the remaining material exposed on the edge of the placement plate. The hopper drains into the hopper, cutting and collecting the waste quickly and efficiently, which can save the manual treatment of the waste, and the treatment method has high economic benefits.
