Abstract: A method is provided for manufacturing interlocking parts, in which at least one part is manufactured by powder injection molding. To compensate for the amount of contraction of one of the parts manufactured by powder injection molding and, if desired, to produce an additional clearance, a separation layer of plastic material is applied between the interlocking parts. After the injection process to form the separation layer, the separation layer and the binder are removed by a binder-removing and sintering process step. The method is also applicable to powdered metal extrusion for manufacture of double-layered metal parts.

Abstract: The damping element for damping translatory motion of a body over a relatively stationary base includes a housing holding a viscous fluid; a friction disk in the viscous fluid in the housing coupled with a shaft extending from the housing; a rotatable drive element having an axis of rotation, connected to the shaft outside the housing, formed so that the drive element can be driven rotatably due to a translatory motion of the body over the base and provided with a cavity coaxial to the axis of rotation; and a coupling device including a free-wheel device in the cavity of the drive element and connecting the friction disk and the rotatable drive element and structured so that rotation of the drive element in one direction results in a torque transferring connection between the friction disk and the drive element, while rotation of the drive element in an opposite direction opposite results in interruption of the torque transferring connection between the friction disk and the drive element.

Abstract: An anchoring means for anchoring by a bonding mass in a drilled hole in a concrete part or the like has a threaded bolt with a reduced portion and an expansion cone followed by a head part, forming at the same time a stop shoulder. Over the reduced portion and expansion cone is slipped an anchoring sleeve which is provided on its outer surface with a plurality of longitudinal grooves. By the longitudinal grooves and the elasticity of the anchoring sleeve consisting of plastics material, the possibility is obtained of compensating for the enlargement of the drilled hole when a crack forms, thus making it possible for the anchoring means to be used in the zone subject to tensile forces.

Abstract: The anchoring rod for anchoring an article to a base using a compounded mass including a synthetic resin, has a threaded portion at its rear end for fixing the article; a threaded nut engagable on the threaded portion for applying a mounting torque; a head having a shoulder facing toward the rear end, an outer surface tapering towards the front end of the anchoring rod and having a wedge-like tip at the front end; a conical portion connecting the head and the threaded portion and tapering toward the head; and a resilient annular washer bearing on the shoulder of the head.

Abstract: An expansible anchor for anchoring of an article to a component includes a shank having a portion of reduced cross-section at a front end, elements for fixing the article at a rear end, an adjoining expander cone at a rear end of the shank, and an expansible sleeve positioned over the shank portion of reduced cross-section and locking elements projecting beyond the diameter of the expansible sleeve. To allow the expander cone to enter the expansible sleeve for expansion of it even in the event the drilled hole becomes enlarged as a result of cracks being formed in its wall, the expansible sleeve is provided with a plurality of longitudinal slits so as to form expander arms. Each of the longitudinal slits extends over at least half the length of the expansible sleeve from a front end edge of the expansible sleeve and continues into an enlarged opening provided in the sleeve.

Abstract: A device for producing drilled holes with an undercut in facing panels includes a drill bit with a drill head that produces an undercut, and a drilling table for supporting a facing panel in which the drilled holes with an undercut are to be produced and displaceable in a plane of the drilling table. A trunnion projecting from a rotatable base member and engaging a bearing secured to the drilling table is movable between a first position in which the trunnion axis coincides with the axis of rotation of the base member, and a second position in which the trunnion axis is eccentric to the axis of rotation of the base member to effect swiveling of the drilling plate when the rotatable base is driven rotatably.The device has a mechanism for moving the trunnion between the first and second positions including a lever pivotally mounted on the base member, the trunnion being mounted on the lever, and a piston-cylinder drive secured to the base member for pivoting the lever.

Abstract: A container for magnetic tape cassettes has a housing having a plurality of insertion openings, a plurality of base plates subdividing the housing into a plurality of individual compartments, arresting elements provided on the base plate and engaging in a reel hub of a cassette to prevent their turning, elements for guiding the cassettes and including complementary guides provided on the housing, elements for stressing a cassette in an inserted position and including a spring element arranged on a rear wall of the housing, and a releasable catch element provided on the base plate and holding a cassette in the inserted position.

Abstract: A carding machine includes a feed roll, a feed table cooperating with the feed roll and defining a nip therewith; and a licker-in arranged for plucking exiting fiber material from the nip. The feed table has an end face which is oriented toward the licker-in and which carries a carding element having carding points projecting toward the licker-in. The carding points are formed by surface roughening or by the provision of a granular coating.

Abstract: The fixing element for anchoring in a hole drilled in a concrete part includes a threaded bolt, an expansible body with an expander cone and an expansible sleeve having an internal bore. The expansible sleeve has longitudinal slots extending from its front end and the expansible body is joined to the threaded bolt for expansion in the drilled hole. To ensure that the fixing element can continue to at least partially hold after experiencing a sever excessive stress such as occurs during an earthquake, the internal bore (14) of the expansible sleeve (11) has a first cylindrical portion (14a) in its front end, which has a length corresponding approximately to the length of the expander cone (5) and the diameter of the first cylindrical portion (14a) corresponds to the smallest expander cone diameter.

Abstract: A light-alloy piston for internal combustion engine, is formed in the piston head with a combustion chamber recess. The stresses which are induced at the rim of the combustion chamber recess by the ignition pressure are reduced by the provision of an inwardly extending blind hole in the portions between the ring groove for the lowermost compression ring and the top apex of the bores in the piston pin bosses.
