The invention also relates to tool arrangements having at least one such shim, and to machine tools having such tool arrangements.

Abstract: A step flashing bending device comprises a supporting a lower press block and an upper press block thereon for movement relative to one another for bending blank metal sheets into step flashing therebetween. The press blocks have working surfaces which are elongate in a longitudinal direction extending at a downward inclination from a top end to a bottom end thereof. The frame and the press blocks are open at the bottom end such that the working surfaces are arranged to automatically release the step flashing from the frame between the bottom ends of the upper and lower press blocks under force of gravity when the press blocks are separated into an open position.

Abstract: A punch for use in molding a workpiece with lubricating oil interposed between the punch and the workpiece includes a straight portion at its end and a diameter-increasing portion. The straight portion includes an end face at its end and a side face. The straight portion extends in an axial direction. The end surface extends in a radial direction perpendicular to the axial direction. The side surface is connected to the end surface. The diameter-increasing portion is connected to the straight portion. The diameter-increasing portion includes a width in the radial direction, which is identical to that of the straight portion, at a junction between the straight portion and the diameter-increasing portion. The width of the diameter-increasing portion in the radial direction increases with distance from the straight portion. At least one of the end surface and the side surface of the straight portion is formed with a pit.

Abstract: A die cushion pad 13 is divided into four small pads 15 and a large pad 16. With this arrangement, a load applied to an action point of each of the small pads 15 can be equalized by the large pad 16, and an overturning moment arising between the action point and a reaction force point that equates the center of the small pad 15 can be canceled, thereby preventing flexure of the small pad 15. Accordingly, since flexure of the cushion pin and the like can be prevented, there is no risk that the cushion pin is frictioned against the penetrating hole of a bolster, and the lifting operation can be smoothly performed, whereby a higher-accuracy pressing forming operation can be realized.

Abstract: A composite anti-friction bearing structure comprising a bearing substrate and an anti-friction layer. The bearing structure can be in the form of bushings, wear plates, wear rings, etc. The anti-friction layer includes particles of an alloy which combines lubricity of molybdenum with the wear resistance and corrosion resistance of elements such as cobalt and nickel. The invention is particularly related to anti-friction bushings for use in die sets, presses and other heavy duty machinery.

Abstract: A master control system for a rolling mill, especially a mill train, having at least one rolling stand driven by means of a drive system, and the master control system having an automation device for the open-loop and/or closed-loop control of the rolling stand. The master control system also has a commissioning computer for the commissioning of the drive system and of the automation device.

Abstract: A machine having a machine tool operatively connected thereto by manually manipulatable fastening members. A fastening member receiving and retaining device is adapted for placement beneath the machine tool for catching fastening members when inadvertently dropped. A device for temporary attachment to the machine or machine adjacent surface, and a flexible cable device are provided for connecting the fastening member receiving and retaining device to the for temporary attachment. The flexible cable device is adapted to be manually positioned and shaped and to retain its shape and position in a self-sustaining manner while holding the fastening member receiving and retaining device beneath the machine tool.

Abstract: Cathode cans for use in air depolarized cells, and cells made with such cans. The side wall is stronger than the bottom wall, and has a smoother outwardly-disposed surface than the respective bottom wall surface. Strength, and thus hardness, of the side wall relates to strength, and thus hardness, of the bottom wall, as hardness of 130-185 relates, to hardness of 93-117, on the Vickers scale. Preferred hardness of the side wall is about 130 to 185; and of the bottom wall is about 93 to 117. The side wall is drawn, and an outwardly-disposed surface of the side wall is ironed. As ironed, the surface finish is related to surface finish of the bottom wall, at the same stage, as surface finish RA of less than 2, preferably about 0.5 to about 1.5, microinches, is related to surface finish RA of about 2 to about 5, preferably about 2.5 to about 4.5, microinches. Thickness of the side wall is generally up to about 85 percent as great as thickness of the bottom wall.

Abstract: Support structure for carrying a vehicle body comprises a pair of spaced apart frames positioned about a front and rear end of the vehicle body. Each frame has an octagon shape formed by joined elongated members. A cross bar assembly of each frame includes a pair of sleeve supports positioned on side members of the frame body and a center member pivotally carried by the sleeve supports. Latching mechanisms at ends of the cross bar assembly limit the degree of center member rotation with respect to the frame body. During use the frames are positioned horizontally so that bottom sections may be slid under respective slightly raised ends of the vehicle body. Mounts on each cross bar assembly then are attached to mounting structure of the vehicle. Next, a top member of one frame is lifted upward which rotates the frame body and lifts that end of the vehicle body. When vertical, its latching mechanisms activate to inhibit further frame movement. Bracing carried by the frame then is attached to the vehicle body.

Abstract: A curtain apparatus having a hood with a top plate in which one or more slots and/or openings are positioned, such as approximately parallel to each other. A fixed woven mesh metal curtain is mounted within one slot or opening so that the fixed woven mesh metal curtain remains in a fixed position with respect to the top plate, during operation of a descaler. A moveable woven mesh metal curtain can be mounted within the same or another slot or opening so that during operation of the descaler, the moveable woven mesh metal curtain translates along a longitudinal axis of the slot or the opening.

Abstract: The present invention is directed to a method for producing a diaphragm for highly brittle metals used in loudspeakers, comprising a step of making a laminated plate by stacking a plate of superplastic material on a plate of highly brittle metal. The laminated plate is arranged on a mould, and the laminated plate is heated to a predetermined range of temperatures, determined according to the highly brittle metal. Subsequently, the laminated plate is deformed by pressuring the laminated plate in the mould, at the range of temperatures. Thus, a diaphragm can be formed from a plate of highly brittle metals, without causing brittle fracture or generating internal or surface defects.

Abstract: The method of gaplessly separating and identifying successive rolling lots of ingots or blooms in a production process for making tubes or the like wherein the stock is introduced into a furnace for heating and in a production line subsequently rolled, which comprises radio-actively marking the first or the last ingot of a given rolling lot of ingots at its subsequently lost end prior to being introduced into the furnace. A further step includes interposing a radio-active radiation responsive signal device in said production line before rolling. Apparatus for carrying out said method includes a device for imparting radioactivity to an ingot in advance of a rotary hearth furnace. Radiation counter-tubes are located in advance of a taper mill and a continuous rolling mill respectively. Further counter-tubes are arranged in advance of a stretch reducing or sizing mill.
