Process for glueing two non-metallic substrates by means of an adhesive

Tubes partly filled with a blend of two or more metals in powder form and containing loose hard bodies are subject to linear and oscillating motion; under the impact of the bodies knocking against each other, the metals alloy together mechanically and form a patterned amorphous coating on the surface of the clashing bodies.

Method for simultaneously mechanically alloying metals and plating parts

Melt extraction of ceramics

A framework template of non-reinforcing material is provided containing, distributed therein and bonded to the building constituents thereof, a reinforcing material such as particles, fibers or whiskers of high tenacity nitrides, carbides, borides, oxides and the like, this distribution being arranged according to some given pattern of orientation and packing density. The template is placed in a mould which is then filled with molten metal which solidifies by cooling. During casting, the constituents of the template may be destroyed by the heat, or they may dissolve in the metal, or they can remain embedded therein.

Efficient in-situ stirring in pressure casting is difficult. Here, the casting die is provided with internal mechanical agitating means which allow homogeneous distribution of the partially solidified phase at temperatures near liquidus and of optionally incorporated reinforcing materials. One form of agitating means is a masher type plate which moves back and forth within the mould.

To unravel a terminal portion of a textile yarn, in particular in preparation for joining that yarn to another one by twisting their ends together, an extremity of the yarn is vibrated to loosen the fibers while a part of the yarn spaced from its end is held fast and the yarn extremity is combed or subjected to an aspirated air stream to remove loose fibers. In a preferred arrangement the air stream also causes vibration of a flexible tongue mounted in an air duct alongside the yarn extremity to oscillate its fibers.

Method of and means for unraveling a portion of textile yarn

The yarn pieces to be joined are stretched between the two pairs of suction tubes (28, 29; 30, 31) and untwisted by being wound about spindles (20, 21). Hot compressed air fed along the surface of two blocks (32, 33) adjacent to the untwisted yarn portions remove free fibers and distribute the fiber tufts in the base of a channel formed in said blocks (32, 33). Said tufts are retained in the base of the channel by an electrostatic field formed with the aid of conductors (46) and the generator (GE). The blocks are then rotated about the rotation shafts (4, 5) until the channel edges are in contact with each other. Air is fed perpendicularly to the plane containing the fiber tufts in proximity to their respective ends in order to cause the fibers of the two tufts to interpenetrate, the spindles (20, 21) then being driven in the reverse direction in order to twist the fiber tufts and to disengage the yarn.
