Abstract: A panel sawing machine comprises a horizontal table (5) on which a movable device (6) pushes a stack of panels (3a) in a forward direction (F) or reverse direction (F1) to feed a sawing device (or to a device for rotating the stack) which divides the panel up into two or more smaller boards. The pusher (6) is equipped with two or more pickup elements (16) that hold the rear edge of the stack in position during positioning and/or sawing operations. The pickup elements (16) are mounted on the movable device (6) in such a way that they can run in guides (15, 15a, 15b) in the following three directions, respectively: horizontal at right angles to, and horizontal parallel to, the forward direction (F) or the reverse direction (F1), and vertical.

Abstract: A workpiece support accessory in the form of a sloping extension panel is coupled for pivotal and horizontal displacement relative to a table-mounted power saw for supporting oversized stock. When an oversized piece of stock is cut, the extension panel prevents the workpiece from inadvertently falling or twisting. A horizontal roller at the delivery end of the workpiece support accessory reduces the friction between the oversized stock and work surface allowing for easy movement during the saw operation. The operator can adjust the horizontal placement of the workpiece support accessory, the slope angle of the extended support surface, the elevation of the horizontal roller and the separation between the horizontal roller and the delivery end of the extension panel.

Abstract: A worktable of a workpiece finishing machine comprises a first worktable and a second worktable. The first worktable has a first joining portion. The second worktable has a second joining portion which is joined with the first joining portion to enable the second worktable to slide back and forth along a predetermined direction provided by the first joining portion, thereby resulting in a change in the area formed between the first worktable and the second worktable for placing a workpiece to be finished by the workpiece finishing machine. The worktable further comprises a locating device formed of an arresting member with a first friction portion, and an actuating mechanism which is mounted on the second worktable and is connected with the arresting member. The arresting member is actuated to move back and forth between a first position and a second position, so as to enable the arresting member to press against the first worktable to attain the effect of locating the second worktable.

Abstract: A worktable apparatus for a machine tool, such as a CNC punch press, a laser equipped machine tool or plasma torch equipped machine tool, which processes a metal sheet or plate workpiece. The worktable apparatus serves a dual function as (a) a worktable that supports a workpiece during processing by a machine tool and as (b) an unloading station for unloading a workpiece or a skeletal remnant produced by the machine tool. The machine tool has a set of workclamps, which move under CNC control along at least one of the numerically controlled axes, grip the workpiece and carry it through the machine for processing. Located on one side of the machine tool, the worktable apparatus has a surface adapted to allow the workpiece to ride smoothly under the motive power of the workclamps.

Abstract: The invention concerns a process for the production of osteosynthesis plates with a varying thickness to whatever degree. The plates are manufactured by a metal cutting process carried out on a composite structure made by a layer of the material which will form the osteosynthesis plate, bound through a layer of adhesive to a supporting layer with high thermal conductivity and mechanical strength. When the cutting process terminates, the osteosynthesis plate is separated from the supporting layer by heating the composite structure until the adhesive melts or by using a thinner suitable for the adopted adhesive.

Abstract: A waterjet cutting head for cutting a moving sheet has a base plate and a cover plate positioned over the base plate. The cover plate includes an upper support surface for supporting the sheet and has depending chamfered sidewalls extending downwardly to the base plate to define a chamber. The upper support surface includes two matrix arrays of circular shaped suction apertures through which air is drawn by a fluid motor to draw the sheet into flat engagement with and over the upper support surface. A waterjet emitting aperture is located in the upper support surface between an upstream suction aperture and a downstream suction aperture in a first general direction relative to sheet travel. A waterjet nozzle is positioned in the chamber below the waterjet emitting aperture for directing a waterjet through this aperture to cut through the sheet. The upstream aperture is positioned partially offset in a direction orthogonal to the first general direction relative to the downstream suction aperture.

Abstract: The invention features implementation of a flat triangular blade which has wo cutting edges and a sharp point. The blade is caused to move pointwise across a cylindrical can's diameter, with the plane of the blade perpendicular to the can's axis, so that the point pierces the can, the two cutting edges slice through the can in both directions around the can's circumference, and the point again, diametrically oppositely, pierces the can. The inventive removal of the residual contents and propellants from a spent aerosol can is optimally effective, because the invention divides the can into two separate parts, concomitantly subdividing the can's internal components.

Abstract: A method for precisely perforating an opening in footwear by positioning the footwear on a foot form with the outsole facing upward, supporting the vamp area of the footwear by a V-shaped support, clamping the rear section of the footwear to stabilize the footwear and moving the footwear upwardly against the die under pressure so that an opening is perforated in the heel area of the footwear. The apparatus includes a shuttle member on which the foot form, the V-shaped support and the clamp are carried. The clamp is activated when the shuttle is moved to contact a limit switch. The footwear is caused to be moved upwardly against the die under pressure upon the operator activating a switch.

Abstract: As a cutter having first and second cutter blades is driven toward a molded ceiling consisting of a base material and a surface material which is attached to the base material in a stretched state, the surface material is first cut by the first cutter blade which is adapted to cut the molded ceiling at a position outside of a predetermined trimming or cutting position such that the trimmed or cut end of the surface material is inclined to have a flat triangular sectional shape. Then, the inclined end of the surface material is cut off together with an excess portion of the base material by means of the second cutter blade which is adapted to cut the molded ceiling at the predetermined trimming or cutting position.

Abstract: A table top machine of box-like construction has a cutting mechanism in its interior and an entry bore that receives a microhematocrit tube. In a first embodiment, the end of a tube inserted into the machine closes a switch that activates the cutting mechanism so that tubes are always cut in the same place, without regard to the ratio of linear space in the tube occupied by red blood cells, clotted blood cells and clear plasma or serum. In a second embodiment, a photoelectric cell positioned at the inner end of the entry bore triggers the cutting mechanism when the end of the tube filled with red or clotted blood cells has passed the eye. Thus, tubes are cut at differing positions along the extent of the tube, depending upon how much each tube is filled with red blood cells or clotted blood cells and how much is filled with clear plasma or serum.

Abstract: Elongated metal stock is advanced intermittently past punch presses which form holes in the stock when the stock dwells. A shear cuts off successive leading end portions of the stock and forms the stock into short pieces. The same machine is capable of running both angle iron and flat stock without making any significant conversons to the machine between runs. This is achieved through the provision of a feed mechanism and clamping units which are adapted to feed and clamp flat stock as well as angle iron.
