Abstract: The present invention provides substituted dibenzoxazepine and dibenzthiazepine compounds of Formula I: ##STR1## which are useful as analgesic agents for the treatment of pain, pharmaceutical compositions comprising a therapeutically-effective amount of a compound of Formula I in combination with a pharmaceutically-acceptable carrier, and a method for eliminating or ameliorating pain in an animal comprising administering a therapeutically-effective amount of a compound of Formula I to the animal.

Abstract: Surface-hardening and smoothing rolling apparatus includes at least one movable rolling device at least including a die carrier with at least one backing element, as well as at least one additional rolling device, the movable and additional rolling device being carried by a standard disposed on a slide, the movable rolling device being arranged so that the position thereof is changeable relative to that of the additional rolling device in a radial plane of a crankshaft to be rolled.

Abstract: A rolling apparatus with a driving mechanism for a workpiece to be rolled and with at least one movable rolling device includes at least a die carrier with one rolling element and a die carrier with one backing element and including at least an additional one of the elements carried by at least one of the die carriers, the rolling element being changeable from one position thereof to at least another position thereof, one of the positions being a working position, at least one of the elements consisting of the rolling element in the working position thereof and at least one backing element associated therewith being kinematically connectible to a power actuating device.

Abstract: Surface-hardening and smoothing rolling machine for rolling at least eccentrically disposed surfaces on a workpiece, having equipment for seating and rotatably driving the workpiece, and comprising at least one movable rolling device at least including a die carrier with at least one rolling element and a die carrier with at least one backing element, the movable rolling device being movable together with the workpiece, and being arranged in a position which is linearly changeable in a radial plane of the workpiece.

Abstract: A crankshaft rolling machine includes a pair of model crankshafts mounted for synchronous rotation. One or more crankshaft rolling units are coupled to the model crankshafts in a manner enabling adjustment of the units along a linear path to adapt the device to the stroke length of a crankshaft to be rolled. The apparatus may be rapidly changed for rolling of crankshafts having different stroke lengths by linearly sliding the individual rolling units relative to the model cranks and thereafter locking the individual rolling units to the model cranks at positions corresponding with the stroke length of the crankshaft to be rolled.

Abstract: The present invention relates to a deep drilling machine including an elongate base, a headstock at one end, a tailstock at the other end, each of the headstock and tailstock being shiftable axially of the base by drive device interposed between the base and each of the headstock and tailstock. A coolant supply apparatus having a chuck member is interposed between the headstock and tailstock at a central position along the base. Devices are provided for enabling the chuck member of the coolant supply devices selectively to face the headstock or the tailstock as desired. The chuck of the headstock is provided with drive device. By the foregoing arrangement a chuck member may be oriented toward the headstock or the tailstock whereby the device may be set up such that either the workpiece or the drilling tool is rotated without the necessity for providing drive device at both the headstock and tailstock ends of the device.

Abstract: A boring tool having a tool head rotatable about its axis and movable in direction of the axis along a working stroke and a return stroke. A knife having a pair of opposite cutting edges is floatingly mounted in a slot of the tool head extending transverse to the axis thereof and tiltable in the slot between a working position and a withdrawal position in which the cutting edges of the knife project a smaller distance beyond the periphery of the tool head than in the working position to prevent damage of the machined surface during the return stroke of the tool head.
