Abstract: The present milling apparatus is constructed especially for milling crankshafts. A milling unit carrying milling cutters is adjustable on guide rails back and forth toward a workpiece such as a crankshaft. The crankshaft is held in respective chucks also supported on the machine base. Continuously adjustable bracing devices interconnect the milling unit with the workpiece supporting chucks on a side opposite the machine base, whereby undesired vibrations are avoided and the tool life is substantially increased.

Abstract: The present milling tool for crankshafts is equipped with an electric hea to assure uniform tool temperatures throughout its operation and to thereby avoid tolerance variations in the milled workpiece. The present milling machine is equipped with contact elements for supplying an electric current to the heater in the milling tool proper.

Abstract: A film of an oleaginous substance is interposed between the surfaces of plastic elements to be joined by a thermal bond. The heat necessary for bonding is obtained by the incorporation of heat generating particles in the bond region, either in the plastic element or in the film. The particles are indirectly heatable by a high frequency alternating magnetic field or other suitable field. This provides a rapid and efficient heating of the surfaces to the bonding temperature, with the oleaginous substance enhancing the bonding action and the properties of the bond.

Abstract: Winding slots in generator rotors which are cut out of the solid rotor block by means of a side mill cutter are finish machined by means of a tool having a plurality of cutting edges disposed linearly one behind the other and displaced with respect to each other by one depth of cut which is guided repetitively, linearly over the slot wall with the depth the tool extends into the slot as well as the depth the tool penetrates vertically into the slot walls being controlled by copying means.

Abstract: A drill for use especially with percussion drilling machines and rotary drill hammers for working rock and concrete is disclosed. The drill includes an elongated shank having a leading and trailing end, the latter of which is adapted to receive axial blows from the drilling machine. A unitary plastic receiving part at least partly encloses and mechanically interlocks with the shank periphery adjacent the trailing end of the shank. The exterior of the plastic receiving art is threaded for engagement with interior threads of a drilling machineadapter.

Abstract: In the process and apparatus for removing the drillings from the drilling te of a drill described, removal is effected through a conduit, extending along the axis of a drill and possibly an adapter for a drilling machine, by a vacuum provided by a compressed-air stream traversing the removal conduit, said compressed air also serving to blow the drillings sucked into the conduit out of the conduit and away from the drilling site.

Abstract: A technique for bonding plastic materials includes placement of minute particles at the interface, either between the interface surfaces or within one or both of the interface materials. A particle-moving field, such as an alternating magnetic field where magnetic particles are employed, is created across the interface to directly and correspondingly impress the alternating magnetic field on the magnetic particles while the interface is in a generally movable or yielding state. The alternating magnetic field continuously moves the particles and by proper orientation causes them to oscillate, rotate or otherwise move within the fluid interface material to move and intermix the plastic material and thereby produce an improved interface bond between the materials. The magnetic particles may be selected to also respond to a radio-frequency magnetic field to rapidly generate heat and thus simultaneously create the fluid material at the interface with the material agitation.

Abstract: A stratified structure suitable for joining first and second thermally bondable bodies exhibiting bonding incompatibility. The structure includes a first layer having bonding compatibility with a first of the bodies, a second material layer having bonding compatibility with a second of the bodies and a metallic mesh interposed between the first and second layers for providing internal cohesion and integrity to the bonding agent. The metal mesh also provides a means by which the structure may be heated as by exposure to an alternating magnetic field. In bonding the first and second bodies, the composite bonding agent is positioned between the two bodies and exposed to the alternating magnetic field to effect heat seals between the bodies and the agent and thus between the two bodies.

Abstract: The present apparatus provides for the automatic shaping and/or cutting of the leads of integrated circuit components which are intermittently advanced to and through a straightening and cutting portion of the apparatus. A base plate is disposed at an angle of approximately 40.degree. to the horizontal and provides a base for the gravitational feeding of integrated circuit components carried in plastic guides both before and after trimming. The untrimmed components are fed by gravity to a metering station whereat a rubber roller is intermittently rotated so that each component is brought in way of a pair of opposed processing blades. These blades are simultaneously advanced by eccentric means which are moved in strict timed relationship to the movement of the component in way of the processing blades. As cutoff blades they cooperate with a center guide die to provide the desired shearing action. Both blades and die may be sharpened several times without losing the desired registration.

Abstract: An improved process of attaching a book body to a case at the hinge to form a hard bound book. A liquid thermoplastic bonding agent is applied to the body or case at the hinge area. The bonding agent is allowed to dry and form a solidified layer. The body is then inserted into the case so that the portion to which the agent has been applied is located at the hinge of the completed book. The dried bonding agent is heatable upon exposure to an alternating electric field and melts to form the attachment at the hinge area. Pressure applied to the hinge area assists in forming the attachment and reduces the thickness and heat generation of the layer.

Abstract: A hose includes a hollow plastic core having an indirectly heatable agent bonded to the exterior thereof by a heat seal. A reinforcing net is embedded in the agent and the composite structure covered with a coating.

Abstract: A container article is formed from a stratified material having an inductively heatable layer. A first article part has a thermally joinable region. A second stratified article part, formed by coextrusion, has a layer containing an oxide susceptor. The container parts are assembled and subjected to an alternating magnetic field to heat the susceptor and thermally join the parts.

Abstract: A stratified structure suitable for joining first and second thermally bondable bodies exhibiting bonding incompatibility. The structure includes a first layer having bonding compatibility with a first of the bodies, a second material layer having bonding compatibility with a second of the bodies and a fibrous stratum interposed between the first and second layers for providing internal cohesion and integrity to the bonding agent by a mechanical interlocking action. In bonding the first and second bodies, the composite bonding agent is positioned between the two bodies and a heat seal effected between the bodies and the agent and thus between the two bodies.

Abstract: A combined skin or rough turning and smoothing roller tool comprising a body having a diametrical slit for a rough turning tool and an axially adjustable basket mounting smoothing rollers axially spaced from the slit. A frustoconically surfaced ring is disposed in an annular recess of the body forming a support surface for the rollers and the body is formed with a feed canal for a cooling-lubricant material. Outlet bores are provided in a space between the slit and the basket and communicate the feed canal with the surface of the body, the latter having a screw thread on an end adjacent the basket for a borehole feed tubing.

Abstract: Uneven wear of the cutting edges of rotating trepanning or drilling tools is avoided by employing at least two cutting blades, by providing a single support strip embedded in an elastically pliable material, and by arranging the cutting blades such, that the resultant force of the cutting forces produced during the drilling operation is directed to the support strip and is of a magnitude such that the lubricant film bracing said strip against the borehole wall does not break away.

Abstract: An improved technique of forming the hinge joint of a hard bound book. An adhesive is applied over the animal glue on the hinge area of the cover and allowed to dry. Thereafter, the body, coated with a synthetic resin, may be joined to the hinge area to bind the book. Priming the animal glue with the adhesive overcomes the bonding incompatibility which has heretofor existed between the animal glue and the synthetic resins and which has resulted in a weakening of the hinge.

Abstract: A drill for rock comprising a boring head arranged on one end of a drill shank and having radially projecting wings, an axial centering projection which projects in a boring direction in front of the wings, said wings and said projection constituting carriers of eccentrically arranged cutter bodies and a centering cutter body, respectively. Breaker surfaces are formed on the wing surfaces between the cutter bodies, respectively, pointing to the centering point of the centering cutter body. Each surface of the boring head located between the wings has at least one jacket line which extends longitudinally to the axis of the boring head and directly joins to a jacket line of the outer surface of the centering projection and is inclined relative thereto at an obtuse angle.

Abstract: An improved method and apparatus for bonding plastic materials includes placement of minute particles at the interface, either between the interface surfaces or within one or both of the interface materials. A particle-moving field, such as an alternating magnetic field where magnetic particles are employed, is created across the interface to directly and correspondingly impress the alternating magnetic field on the magnetic particles while the interface is in a generally movable or yielding state. The magnetic particles, either as a result of premagnetization or in response to the impressed magnetic field, form individual magnets which move to align themselves with the impressed field in accordance with the direction of the relative polarizations.
