Abstract: NONCONTACT FULL-LINE DYNAMIC AC TESTER FOR           INTEGRATED CIRCUITS     ABSTRACT OF THE DISCLOSURE            Simultaneous noncontact testing of voltages across a full line of test sites on an integrated circuit chip-to-test is achieved with high time resolution using photoelectron emission induced by a pulsed laser fo-cussed  to  a  line  on  the  chip-to-test,  together  with  high  speed electrostatic   deflection   perpendicular  to   the   line   focus. Photoelectrons  produced by the line focus of pulsed laser light are imaged to a line on an array detector, the measured photoelectron in-tensities  at array points  along this line representing voltages at corresponding points along the line illuminated by the  laser  focus. High  speed electrostatic deflection applied during the laser pulse, perpendicular to the direction of the line focus, disperses the line image (column) on the array detector across a sequence of sites at right angles (rows), thereby revealing the time-dependence of voltages in the column  of test  sites with high time resolution (in the picosecond range).

Abstract: COMPRESSED BLOCK CODE FOR FACSIMILE TRANSMISSION           ABSTRACT            A coding process for a facsimile transmission system employs block coding and dither matrices of black and white picture elements, wherein each matrix represents a portion of a subject.  The subject is scanned to provide gray-scale tone-level data, and the data of continuous tone regions of the subject is represented by standardized patterns in matrix form.  A run of identical patterns is counted in the scanning direction and a symbol indicating the number of such repetitions is placed in the code in lieu of the succession of code words representing individual ones of the repeating patterns.  A second symbol is inserted into the code to indicate a succession of runs of repeating patterns in the same column now positioned in two or more rows. The second symbol is utilized in lieu of a repetition of code words corresponding to each of the repeated patterns.  The two symbols provide for two dimensional compression of the length of the message for improved efficiency of transmission of pictorial data between the subject and a display of an image of the subject.

The process is a froth flotation process utilizing a novel collector emulsion, which is an emulsified mixture of: a secondary amine modified sulphonated fatty acid, a high rosin containing tall oil fatty acid, an anionic petroleum sulphonate, and a high molecular weight primary amine.           The collector emulsion mixture is added to the aqueous slurry of the comminuted rare earth metal compound containing oxidic mineral, which has been previously conditioned in a conventional manner.  The conditioning reagents may include alkaline pH modifiers and gangue depressants such as citric acid, oxalic acid, sodium silicates and fatty acids.           The rare earth metal compounds will be concentrated in the froth, and are separated in the conventional manner.

Abstract: ABSTRACT OF THE DISCLOSURE          According to the present invention, a file recovery system is provided in which the commands for recovering files such as a historical file are unneces-sitated and the recovery system configuration is independent of the host processing system.  That is, since the equip-ment for achieving a file recovery does not have an information about the location of the recovery data, an information about the content of a file to be recovered is transmitted to a transmission line.  The other equip-ments asynchronously receive the information and judges whether or not a file containing the same file exists in the own system.  If the file exists, the content of the file is transmitted to the transmission line.  The equip-ment achieving the file recovery asynchronously receives from the transmission line the file data of files such as a historical file and establishes data consistency by use of the buffered current data and the event number, thereby recovering files such as a historical file.

Abstract: CONNECTOR FOR ORTHOGONALLY MOUNTING CIRCUIT BOARDS               ABSTRACT OF THE DISCLOSURE           A connecting device is disclosed for electrically and mechanically linking multiple circuit boards arranged in two perpendicular stacks.  The connecting device includes two identical connectors, each with a plurality of outwardly extended electrical socket contacts, and a pair of opposite, electrically insulative shoulders projected outwardly beyond the socket contacts.  Electrical pin contacts are recessed into the shoulders.  The pair of connectors can be engaged when in facing relation, with one of them rotated 90° relative to the other.  As the connectors are moved toward engagement, each shoulder of each connector enters into a nesting relation between the opposed shoulders of the other connector, pre-aligning the opposed pin and socket contacts.  The shoulders have inclined edges at their outer faces, to assist in capturing their associated opposed shoulders and guide them, in a self-aligning manner, into the nesting relation.  The connectors require a 90° angular offset for their engagement, and thus facilitate interconnection of circuit boards in orthogonal stacks.

Abstract: A Spread Spectrum Code-Division-Multiple-Access (SS-CDMA) Lightwave Communication System Abstract The present invention relates to a lightwave communication system, and associated transmitters and receivers,      which uses both spread spectrum, code-division-multiple-access (SS-CDMA), and wavelength-division-multiplexing (WDM) techniques for 2-way transmissions over a lightwave waveguide arrangement      to use the overall spectrum of the waveguide arrangement      while providing sufficient interference rejection of randomly spaced carriers, and associated signals, which may drift into the bandwidth of transmissions of other transmitter/receiver pairs due to instabilities in carrier laser sources Techniques are also disclosed for a transceiver acquiring a 2-way link with another transceiver, while other transmitter/receiver pairs are concurrently communicating using WDM, SS-CDMA, signal transmissions. For example, a calling transceiver transmits a narrowband information message      on a random carrier which is detected by a called transceiver by scanning the frequency spectrum.  The called transceiver then returns a narrowband answer signal   on another random carrier which is detected by the calling transceiver. In this manner, each transceiver locks onto the carrier of the other transceiver and the appropriate pseudo-noise (PN) code sequence can then be determined and synchronized before WDM, SS-CDMA, 2-way transmissions begin.

Abstract: Abstract:    The invention relates to a method and apparatus for treating non-ferrous metal drosses in order to recover the free metal contained therein.  The dross is heated by a plasma torch in a rotary furnace.  The plasma heating and rotary motion make it possible to recover metal from the dross without employing the conventional salt bath.  This means that the gases exiting the furnace can be treated more easily to remove pollutants and the solid residues can be discarded without risk of causing environmental pollution. By controlling the speed of rotation of the furnace, large dross lumps can be accommodated and so the conventional grinding and screening procedure of the dross can advantageously be eliminated.

Abstract: A sloping roof construction has a supporting structure 72 and a number of roof slabs 74 which are mounted thereon, are elastically flexible and are convexly curved in the outward direction. The roof slabs are mounted such that they partially overlap one another, the lowermost marginal part of each slab overlapping the uppermost marginal part of an adjoining, lower placed slab. Each roof slab is fastened to the supporting structure by means of nails 75, screws or other fastening members in a part situated between the uppermost and lowermost marginal parts of the slab. The originally curved slab is fastened in an at least partially flattened state, the uppermost and lowermost marginal parts being pressed pliably against respectively the supporting structure 72 and the outer surface of the adjoining lower placed slab. The curved roof slabs 74 for a roof construction of this kind can be made of a layer 37 of a plastic, deformable material, for example a cement mixture, which can be reinforced by fibres. This material layer can be applied to a curved support surface 70 such that the material layer assumes a similar shape to the support surface.
