Abstract: In the operation of cutting a metallic work material, if the rotation of an electric motor 21 is reduced by a reduction gear mechanism including a gear mechanism and transmitted to a main shaft 23 and the metallic work material is cut by a circular saw 28 attached to one end of the main shaft, the moment of inertia I (kgf·m·sec2) of the main shaft is set to be more than F×(D/2)/[1000×250×(N/60)2] while an outside diameter of said circular saw is D (mm), the number of revolution is N (rpm) and a cutting force per tooth as a component of force in tangential direction is F (kgf). By so setting, at the initial cut positions of the work material and in a region in which the number of cutting related teeth Zi is 1.0 or less at the final cut positions, the moment of inertia is high compared with a cutting torque applied to the main shaft by intermittent cutting resistance, so that the rotational variation of the main shaft is very small.

In addition, a reamed bolt connection is provided.

Abstract: A continuous flighted conveyorbelt (18) is fed product (12) from a transverse direction. As the belt moves the product forward, offset water jets (56) cause some of the items not seated in a flight (20) to be rotated and captured in the flights. Further movement brings the product (12) to a zone where water jets (72) force all items to one side against a registration plate (76). Excess product and items not captured are forced off the surface of the belt by water jets (62) and are carried away to be fed again. A cutting blade (84) is set an appropriate distance from the registration plate (76) to trim product captured and registered. The products are then forced across the width of the belt by repositioning water jets 102 and stop against a second registration plate (104). A belt (82) covering the top of the belt flights (22) prevents items from escaping through the top of the conveyor.

Abstract: An automatic log-cutting apparatus, or log merchandiser, which is designed to analyze and rapidly process tree-length stems, or logs, into shorter segments for further processing in pole mills, sawmills, plywood plants and the like. The logs are loaded via a conveyor onto the support arms of a number of cutting stations, all of which are movable and pre-positioned according to the determined optimum cut locations. The logs are then cut by pivoting saw blades, and the cut segments are released by the support arms onto a conveyor for removal.

Abstract: A locking mechanism for scissors-type shear allows closing and locking of the shear even when the locking element is placed in a locked position before the shears are closed. The shear includes first and second blade assemblies pivotably connected to one another. Each blade assembly includes a blade and a handle. A locking mechanism is slidably mounted on a first handle. The locking element is moveable between locked and unlocked positions. In the locked position, the sliding lock mechanism engages a catch element on the second handle to lock the shear in the closed position. The locking mechanism includes resilient arms and the catch element includes inclined cam surfaces. When the locking mechanism is placed in a locked position before the shear is closed, the ends of the resilient arms engage the inclined surfaces of the catch element, allowing the resilient arms to flew outwardly and pass over the catch elements.

Preferably, the main handle, the auxiliary handle and the indicator are arranged so that, in the cutting position, the operator can view the saw blade as the saw blade cuts the workpiece and can view the indicator. The operator holds the main handle with one hand and the auxiliary handle with the other hand.

Abstract: A transparent self contained spoon which includes a food storage tank and a manually operable food dispensation valve and which allows food to be dispensed into the bowl of the spoon conveniently and without spillage. The feeding spoon has a flattened bowl at one end for supporting soft foods or liquids as they are placed into the mouth. The other end of the spoon is branched to form two completely separated structures, the handle and the food storage tank. The handle is linearly aligned with the bowl of the spoon, and the food storage tank extends upwardly from the handle at an angle. The food storage tank is hollow, and has an increased diameter relative to the handle so as to accommodate several ounces of soft food or liquid. By mounting the food storage tank at an upward angle relative to the bowl of the spoon and handle, gravity is used to urge the food material into the bowl portion and complicated mechanical parts are not required to propel the food toward the bowl of the spoon.

Abstract: A folding knife with a safety for blade is provided. When a blade of the folding knife has been turned to an extended position, a slip switch of the safety for blade is moved to a safety lock position to depress a push element, so that the push element engages a lower end with a first locking hole on the blade, preventing the blade from undesirably closing in the event a blade lock of the folding knife is unexpectedly released or the blade is subject to an over big impact. On the other hand, when the blade has been turned to a folded position in a handle of the knife and the slip switch is moved to the safety lock position, the push element engages its lower end with a second locking hole on the blade to prevent the blade from undesirably separating from the handle. The safety for blade therefore provides the folding knife with a further means to ensure the safe use of the folding knife.
