Patent CA-2630403-A1 (CA)
Title: Wear assembly
Inventor: MCCLANAHAN ROBERT
IPC: E02F9/28
Filed: 2006-12-04
Abstract: In a wear assembly for securing wear members to excavating equipment, a spool iis used with a wedge to hold the wear member in place. The spool is formed with at. least one laterally extending arm at its upper end in lieu of an axial arm such as useid in a conventional C-shaped spool. In this way, the spool can be easily supported in the assembly as the wedge is installed. The spool does not fall through the opening and no special care is needed to prevent it from falling. The spool also holds itself in place when the wedge is driven into the passage. As a result, installation of the wear assembly is easier and less hazardous. In addition, the lateral support reduces the risk that the spool will suffer spreading.

Abstract: The invention relates to a method and a device for the production of stampings with almost smooth cutting and enlarged functional surface, especially fine blanking and/or forming a workpiece out of a flat strip, wherein the flat strip at closing is clamped between an upper part consisting of a shearing punch, a pressure pad for the shearing punch, an arranged on the pressure pad V-shaped projection and an ejector and a lower part consisting of cutting die, ejector and an inner form stamp and in the cutting zone is enforced a cut by shearing at high compressive stress, wherein the V--shaped projection has been pressed into the flat strip beforehand and a compressive stress acts on the flat strip to be cut.   The invention has the task to avoid tears at cutting and functional surfaces of fine blanking parts by systematically controlling the state of stress in the cutting zone and at the same time to make it possible to economically and effectively realize the fine blanking of thicker parts with higher process security and reduced edge rollover.   This task is solved by adjusting the state of stress in the cutting zone to a position oriented compressive stress from the beginning of the cutting process to its end by a movement slightly retarded with regard to the movement of the shearing punch additionally pressing in material in a direction almost perpendicular to the cutting direction by means of a tool element acting with controlled force depending on the part geometry and the thickness of the workpiece parallel to the cutting line between shearing punch and cutting die.     Fig. 4 is to be designated as main drawing.

Abstract: An optical sampling device and an optical signal monitor device are comprised of an optical synthesizing unit for synthesizing a sampling subject optical signal and a sampling optical pulse, and an electric field absorption type optical modulator. The electric field absorption type optical modulator is provided with two optical terminals for projecting and receiving light, and an electric power source terminal to apply an electric field to an optical path to connect the two optical terminals. The electric field absorption type optical modulator has a characteristic that changes an absorption rate of light propagating through the optical pathin response to the magnitude of the electric field, receives projected light through one of the two optical terminals from the optical synthesizing unit, and makes the absorption rate high when the sampling optical pulse is not incident while lowering the absorption rate when the sampling optical pulse is incident. The optical sampling device and the optical signal monitor device further include a direct current electric power source to supply a predetermined direct current to the electric power source terminal, and an optical separating unit for selectively projecting the sampling subject optical signal component out of the optical signals projected from the other terminal of the two optical terminals.
