Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus are disclosed for cryogenic treatment of materials,  Liquefied gases are used for cooling instead of refrigeration units, thus avoiding maintenance of such units, and there are not the same constraints on chamber size as occurs with refrigeration units.  The process comprises inserting a predetermined quantity of a liquid gas into an enclosed insulated container to vaporize, reduce the moisture content, and purge air; recirculating the vaporized gas within the container to maintain a substantially uniform temperature therein; cooling the container at a predetermined rate, and maintaining the container at a minimum temperature for a predetermined period of time; and heating the recirculat-ing vaporized gas to raise the temperature at a predetermined rate.  The apparatus comprises an enclosed, insulated container having a sealed lid in the top thereof, open evaporator for liquid gas within the container, recirculating fan and duct means for maintaining substantially uniform temperature within the container, a primary cooling coil for liquid gas within the container, main cooling coils for liquid gas within the container, and heating means within the duct means.

Abstract: PHF 80.592               16 ABSTRACT:        Semiconductor device for use in bistable memory cells having two transistors with two emitters for use in emitter-coupled logic.  In such a cell one of the emitter regions of each transistor is integrated in a lateral extension of the base region which serves as a resistive zone.  The pinching zone which is situated below one of the emitters obtains a selective overdropping with respect to in particular the pinching zone which is present below the other emitter.  As a result a good ohmic value for the resistive zone is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE      A weatherproof housing and rotatable cover have radial lugs which are engaged when the cover is closed in a specific position and rotated clockwise.  The cover is hingedly attached to the housing by a J-shaped arm and the cover has a skirt, one surface-of which faces walls formed on the arm.  The skirt has cam and stop surfaces defining a recess which engages a wall on the arm in the specific position, acting as a detent to inhibit rotational movement of the cover when it is open. Limited tilting movement of the cover is permitted by a sin-uous spring in the mounting of the cover on the arm. A stop pin on the skirt prevents the cover from being rotated by 180°.

Abstract: ABSTRACT     The present invention provides for the heat treatment of a solid object with electron beam energy Electrons are generated and propagated within a vacuum along a predetermined direction and in a linear beam that extends transverse to that direction.  The beam is converged into a fine line of intense charge and impinged on a .region of the object being treated.  The kinetic energy and the power density (flux) of the beam and the time for which the beam impinges on the object axe regulated to limit the depth of penetration of the object by the electrons and to provide a layer of the ob ect in the region being treated, which layer has a maximum depth of the order of microns, with a temperature that is high enough to effect heat treatment of the layer while thermal diffusion to the solid material underlying the layer is largely precluded.  The present invention allows for annealing, welding, etching, curing, cutting, polishing and surface alteration of the solid object, and has been found particularly useful for melting a layer of semiconductor material having a small grain size for epitaxial recrystallization into a semiconductor having a large grain size

The assembly includes a first nut part having an internal thread complementary to the external thread of the screw, and a second nut part also having an internal thread complementary to the external thread of the screw.  A coil spring is interconnected between the first and second nut parts for applying torque thereto and rotatably biasing the nut parts together to eliminate backlash therebetween and improve the positional accuracy of the nut assembly along the screw.          A cylindrical collar is sandwiched between a pair of opposed por-tions of the nut parts and surrounds the coil spring.  With this structural combination, the anti-backlash nut assembly can be adjustably preloaded by relatively rotating the nut parts to selectively preload the coil spring to a desired torque.  The assembly then is rotated onto the screw with the torsion spring so preloaded.
