Abstract: ABSTRACT This application is directed to an electromotive pro-cess for exciting a chemical species which includes orientating, re-positioning and transporting and for the separation of chemical species on a support.  Unlike conventional semiconductive tech-nology in the solid state and amorphous state, the present pro-cess is directed to electrically induced molecular transport in semiconductive media, as distinct from charge transport alone.       The semiconductive medium is generally of the liquid, gas or gel form.      The process of this invention is characterized by a high mobility rate in the separation process which is achieved by tailoring a semiconductive medium for operation over a wide range of voltages at low current density.  The voltage applied is preferably in the range of about 0.05 to about 25,000 volts/cm.   The semiconductive media used in this invention generally comprise several components which are chosen to give a current density in the range of about 0.001 to 400 micro amp/cm2 on filter paper as a substrate.  The media should also have a high boiling point.  A further aspect of the process is that an external cooling means is not ordinarily required.

Abstract: ABSTRACT:        This transition detector is intended to supply pulses which characterize the instants the signal passes a threshold. This signal, which appears in a rectangular form is applied to a first integrator which supplies a signal which increases or decreases in accordance with the sense of the rectangular sig-nal and to a branch which comprises a series arrange-ment of a delay circuit and a second integrator which is identical to the first. The outputs of the two in-tegrators are connected to a comparator which supplies the desired pulses. At least at the start, the output of the first integrator is entered in a store at a given instant and at an instant which is so much later as the delay supplied by the delay circuit the second integrator is forced to assume the value stor-ed in the store.        Use: Clock synchronization in a data trans-mission system.        Reference: Fig. 1.

Abstract: ABSTRACT      To start up a converter station of a high-voltage d.c. transmission system, the station being initially not connected to any functioning three-phase system, the active power required is drawn from the d.c. side of the converter station, and the reactive power required is drawn from an independent reactive power source.  The latter is initially run up to the a.c. operating voltage and frequency, whereupon the controllable rectifier elements of the converter station are triggered.  During run-up, converter losses may be made up by an active power source on the a.c. side e.g. a Diesel stand-by generator.  The converter station can then be used to transmit power from a network to start a generating plant associated with the converter station, after which the generating plant can feed the network through the converter station.  The converter station may be part of a HVDC transmission network, or of an internal HVDC block of a generating plant.

Abstract: ABSTRACT OF THE DISCLOSURE A finishing welt, comprised of a reinforcing polyethylene rod surrounded by a fabric scrim and an outer encasing layer of polyvinyl chloride, is formed in an extrusion-embossment method and apparatus.  The method includes feeding a composite preform, consisting of the polyethylene rod and the scrim, first through an essentially key-hole shaped passageway in a core pin of an ex-truder crosshead and then into a chamber within the crosshead where plastic material under pressure flows onto the preform.  Immediate-ly thereafter, the preform is conveyed through an essentially key-hole shaped orifice, where the welt is formed by extrusion.  Next, the opposed sides of the welt are sequentially embossed as the welt is conveyed over external peripheral embossing surfaces of two spaced rollers.  The resultant welt is essentially key-hole shaped in cross-section, with the scrim surrounding the rod within the enlarged head portion of the welt and extending into the smaller depending flange portion.  As a result of the extrusion step, the outer encasing layer of polyvinyl chloride is bonded through the scrim in the welt flange;  and as a result of the sequential embos-sment, the outer surface of the welt is free of any significant longitudinal rib.

Abstract: SYSTEM FOR AUTOMATICALLY PROOFREADING A DOCUMENT          ABSTRACT:    Spelling errors in a word processing system are de-tected and presented to the operator for correction at the end of a document page.  A dictionary memory contains repre-sentations of the correct spellings for words most frequently used.  As each word is typed, it is stored in a word queue where it is compared to the contents of the dictionary memory.  If the compare is unequal, then the word and its location on the page is stored in an error memory.  When an end of page indicator is set the printer automatically repositions the print head at the ending character of the first word in the error list.  When the operator keys in the correct spelling, the printer is caused to remove the mis-spelled word from the page and type the correct spelling.          The corresponding word in the error memory is also corrected.          As each misspelled word in the error memory is corrected, the remainder of the memory is scanned and repetitions of the same spelling error are automatically corrected.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved method and apparatus for the submerged-arc cladding of a metallic work piece, which has an obstruction extending generally transverse to the surface to be clad, with a metal electrode strip that melts in an electric arc while forming a weld bead on the work piece.  In this type of cladding apparatus, there exist means for moving an electrode strip and a work piece relative to each other and for passing an electric current through the electrode, creating an electric arc between the work piece and the electrode.  The electrode strip melts, and a cladding layer is thereby deposited on the work piece in a generally linearly cladding zone.  Such an apparatus also includes means for depositing a welding flux that covers the region of the electric arc and leaves a proportion of the weld bead still in its molten state.  The flux covering provides a layer of molten flux to cover the molten metal.  In addition, the cladding apparatus includes magnetic poles of opposite polarity positioned adjacent opposite edges of the electrode strip for the purpose of agitating the molten metal by agitating the molten flux in contact with it.  According to the improved method and apparatus, the magnetic flux is  caused to travel through the obstruction so the obstruction itself forms a magnetic pole.  In a preferred aspect, the electrode strip would be inclined away from the obstruction in the plane of the strip to facilitate strip cladding in a corner formed in the work piece by  the obstruction.
