The rotational speed of a rotary drum with a rubber sample attached on the outer surface is set to a desired rotational speed, the impact cycle for the surface of the rubber sample of the contact member by the repeat-impact mechanism is set to a desired cycle, the impact load by the contact member is set to a desired impact load by a weight member, a desired contact member is selected from among the plurality of contact members with different specifications, and the contact member is repeatedly made to collide with the surface of the rubber sample by rotating a vertical excitation roller and pivoting the arm portion in the vertical direction with a rotation shaft.

Abstract: According to one embodiment of the invention, a method includes generating a person-name Information Gain (IG)-Tree and a relation IG-Tree from annotated data. The method also includes tagging and partial parsing of an input document. The names of the persons are extracted within the input document using the person-name IG-tree. Additionally, names of organizations are extracted within the input document. The method also includes extracting entity names that are not names of persons and organizations within the input document. Further, the relations between the identified entity names are extracted using the relation-IG-tree.

Abstract: A device for planishing a band saw blades or the like, includes elements for continuously driving the blade, elements for detecting deformations of the blade and planishing elements. The detecting elements consist of position sensors integral with a table positioned underneath the blade, the sensors being uniformly spaced on a line transverse to the forward moving direction of the blade, and the planishing elements consist of hammers co-operating with an anvil positioned underneath the blade, such that, when a sensor detects a deformation of the surface of the blade body, the hammer corresponding to the sensor is actuated to even out the deformation.

Abstract: Procedure for straightening a circular-saw blade (2), in which procedure the blade (2) is mounted on a shaft (3). The geometry of the blade is measured, the measured values are compared with reference values, deformations in the blade are straightened by means of blade treating elements (10, 11, 12, 13, 14, 15, 16, 23, 24), the blade is tensioned by means of working devices (13, 14), the blade (2) is rotated, lateral forces are applied to the blade (2), the effect of the forces on the blade (2) is measured while the blade is rotating, the measured values are compared with the reference values, and some or all of the operations mentioned above are repeated, if necessary, in a desired order, until the desired rigidity and straightness of the blade (2) have been achieved. The invention also relates to an apparatus for straightening a blade.

Abstract: A locking apparatus for vehicles of the present invention is constituted by a rigid lock body and a hook. The hook is connected to the lock body in a ring shape such that, at least one end thereof can be separated from the lock body. The lock body includes a moving plate which engages with and disengages from the separating end side of the hook, responding to the external operation for unlocking and locking, and an operating shaft capable of reciprocating in an interlocking fashion with the moving plate. On the operating shaft, a plurality of dials are respectively disposed rotatably via bushes. Between the dials and the bushes, an unlocking code sequence setting mechanism for setting an unlocking code sequence freely is formed, and between the operating shaft and the bush, a lock mechanism is formed.

Abstract: Ball units for conveyor systems are known in which a load-bearing ball is seated in an essentially radially symmetric bearing unit having ball bearings in a bearing shell. The load-bearing ball is held in the bearing unit by a securing apparatus. The bearing unit has a supporting structure that enables the bearing unit to be fixed in an opening of a carrier plate in such a way that it can support a load. Detents are provided to lock the unit in the opening against the load direction. It is suggested that the bearing shell should be constructed integrally with the supporting structure as a semielastic formed element.

Abstract: An apparatus for the straightening (dressing or peening) of relatively large circular-sawblade blanks, especially for hot-sawing circular saw blanks, comprises a stand for a forging hammer which is provided with a pneumatic peening hammer directed upon a working point and a support which is linearly shiftable relative to the hammer. The hammer is vertically reciprocatable and the translation direction of the support is horizontal and perpendicular to the axis of the hammer. The support comprises linearly-shiftable carriage provided with a table which can be rotated about a vertical axis through at least 180.degree. and the peening portion of the hammer is also rotatable about a vertical axis through at least 90.degree..

Abstract: A method and machine for hammering circular saw blades automatically, to correct uneven distributions of residual stresses, and distortions of the blade surfaces from true planes, so that the blades will run true. This operation has previously only been performed manually, by highly-skilled craftsmen. The saw blade is elastically deflected so that its normally-planar surface lies in a curved surface of a predetermined contour. A proximity sensor passes over the blade to detect deviations of its surface from the predetermined contour, which occur at points of uneven stress distribution or surface distortion. At such points, the blade is arrested and hammered until the fault is corrected.
