Abstract: ABSTRACT OF THE DISCLOSURE           Fluorosilicic acid solutions, which normally undergo decomposition when distilled, thereby creating unwanted forms of SiO2, are rendered stable during dis-tillation by providing in the fluorosilicic acid solution an amount of HF which is at least about 10 parts of HF per 36 parts of H2SiF6 and an amount of H2O which is at least about 54 parts of H2O per 36 parts of H2SiF6.          The mixture is distilled to remove any excess H2O and excess HF that is present, without encountering forma-tion of SiO2, until an azeotropic solution containing about 36% H2SiF6, about 10% HF and about 54% H2O is reached.  The ternary azeotrope, being of constant quality and concentration, is more suitable for use in various processes, such as processes for making fumed SiO2, than H2SiF6 solutions which are not of constant quality or concentration.

Abstract: ABSTRACT OF THE DISCLOSURE:            A continuous casting installation has a curved roller apron and a withdrawal and straightening unit.  The latter has upper and lower rollers, and the upper rollers are vertically movable so that a gap may be formed between the same and a strand which extends into the withdrawal and straightening unit.  A heating device is provided for the strand and may be moved from a position laterally of the withdrawal and straightening unit into the gap between the upper rollers and the strand when the upper rollers are raised.  The heating device is preferably arranged in the region of the tangent point.  When a strand cools to such an extent that the withdrawal and straightening unit can no longer bend it, as may occur in the event of a breakout, the upper rollers beyond the tangent point are raised.          The strand is then driven forward until, by virtue of its curvature, it touches the raised upper rollers.  Due to the curvature of the strand, the latter touches the raised upper rollers at a location spaced from the tangent point and a gap exists between the raised upper rollers and the strand over the span from this location to the tangent point.  The heating device is inserted in the gap and the strand is heated at a selected location to a temperature such that its resistance to bending is lowered sufficiently for it to be bent by the withdrawal and straightening unit.  The upper rollers are lowered and the strand is bent at the selected location.  The preceding operations are repeated until the strand can be removed from the installa-tion.

Abstract: ROTATIONAL MOLDING APPARATUS AND PROCESS     ABSTRACT OF THE DISCLOSURE         An apparatus and process is disclosed for rotational molding.  Rotational molding is a technique for the fabrication of parts from powdered thermoplastic material in which the thermo-plastic material is placed within a hollow mold and the mold is rotated in a heated environment until the thermoplastic material fuses and coats the entire interior surface of the mold.  Included in the apparatus is a holding mechanism for the mold and a power mechanism to provide the required rotational motion to the mold.          The power mechanism provides for simultaneous rotation of the mold about two orthogonal axes and is displaced spatially from the holding mechanism.  The holding mechanism is attached to a trans-lating mechanism which positions the molds both internal to and external of a heating chamber such as an oven while keeping the drive mechanism external of the oven at all times.        More specifically there is disclosed an apparatus which includes a truck mounted upon a guiding track and having extending therefrom an arm mechanism.  The arm is pivotally attached to the truck and is coupled thereto in such a manner that the arm may be translated about the pivotal point through a vertical path from a horizontal Position at a loading/unloading (mold rework) station through approximately 180° to be positioned into a heating chamber at a heating station and a cooling chamber or tower at a cooling station for fabrication of the molded part.  Subsequently thereto the mold attached to the arm may be repositioned at the mold re-work station for the removal of the plastic Part from the mold.          Automatic control mechanisms and interlocks are provided to enable safety measures to be exercised to prevent movement of the truck along the track except specified times and when the arm is in - 1a -appropriate position to clear the oven and cooling towers.

Abstract: METHOD FOR FABRICATING ULTRA-NARROW METALLIC LINES            ABSTRACT OF THE DISCLOSURE         A method for fabricating very narrow superconducting metallic lines on a substrate using ion-implantation and etching techniques.  The method permits lines to be produced which are much smaller than those fabricated by conventional masking and etching techniques.  It makes the fabrication of very small Josephson and other superconducting devices possible.  Also since lines are formed in metals, they have high conductivity, so are useful as ordinary conductors at high temperature or when the technique is utilized with non-superconducting materials.  The method includes the steps of depositing a selected metal film on a substrate, applying a photoresist or other masking pattern and exposing, etching away the exposed region, ion-implanting the edge of the resulting pattern, removing the photoresist and etching away the unimplanted portion of the metal leaving an ultra-narrow line pattern.

Abstract: CHEMICAL ANALYZER          ABSTRACT OF THE DISCLOSURE    To control a chemical analyzer, a program counter sequen-tially energizes the row conductors of a bus-bus type program card, with the columns being connected to a command interpreter prearranged to distinguish between commands not requiring a data input and commands that require a data input.  Commands re-quiring a data input automatically permit sequencing to the next command which is a data readout while inhibiting the out-puts from the conductors that provide commands for operations not requiring data such as the operations of raising and lowering pipettes or moving chemical receptacles one position.  The data is read through a decoder while the sequencing is temporarily inhibited and the command outputs are inhibited.  An additional command is provided by a direct signal from the program counter with no conductive connection between the rows and columns of the program card.
