Abstract: ABSTRACT           A process is provided for the production of solvent refined coal, which comprises heating the coal whilst slurried in a solvent under hydrogenation conditions to substantially liquefy the coal followed by a step of separating the non-dissolved solids from the solu-tion, e.g.  by filtration, improved by the feature that a small percentage of the liquefiable matter of the coal is combined or recombined chemically with itself and/or  existing insoluble matter so as to form aid, assist in the separation of the solids from the liquid.  These larger particles may be formed by hydrogen starvation during the heating of the slurry to the coal liquefying temperature or by controlled localised overheating prior to the liquefication step or by reducing the hydrogen partial pressure during the liquefication step to a value somewhat below a predetermined value for maximum extraction or by a posttreatment of the liquid product of the liqueri-cation step at a temperature higher than the coal liquefication step.  Two or more of these possiblili-ties may be employed in combination.

Abstract: Abstract of the Disclosure A cylindrical strand with a thermoplastic outer shell (e.g., plastic insulated wire) is bonded along its length to a similar or different cylindrical strand by laser heating.  The strands are brought into contact with one another at a contact point.  A laser beam of selected power and wavelength is directed at the contact point in a direction approximately parallel to the axis of the strands as the strands are carried past this point.           Absorption of the light by the plastic causes melting of the thermal energy into the plastic is controlled by selection of the wavelength of the laser radiation relative to the absorption spectrum of the thermoplastic material.  The laser power level is adjusted to control the total energy  input in accordance with the strand feed rate.

Abstract: AUTOMATIC BEAM CURRENT LIMITER            Abstract of the Invention An amplifier for combining color difference signals with luminance signals and for driving a color image reproducing device includes first and second tran-sistors of opposite conductivity type.  Color difference signals are coupled to the base of the first transistor.          The emitter of the first transistor is direct current coupled to the emitter of the second transistor.  Luminance signals are coupled to the base of the second transistor.          Color signals developed at the collector of the first transistor are coupled to the image reproducer.  A clamping circuit operates during the horizontal retrace interval to clamp the emitter of the first transistor to a voltage to control the operating point of the amplifier.  The voltage is related to the magnitude of the electron beam current drawn by the image reproducer in a manner such that after a predetermined amount of beam current has been drawn, the generation of the electron beam is in-creasingly inhibited with increasing beam current.  Since the amplifier which is controlled is supplied with both luminance and chrominance signals, excessive beam currents due to chrominance signals, as well as luminance signals, are inhibited.

Abstract: AUTOMATIC FUNCTION MECHANISM FOR TYPEWRITERS             ABSTRACT OF THE DISCLOSURE         A method and mechanism for automatically performing a typewriter function such as backspacing a carriage where the backspace mechanism is actuated upon removal of an insertable and removable ribbon cartridge.  Particularly adaptable to correcting typing errors, the present invention will automate the final backspacing operation that is necessary before the correct character is typed and normal typing can be continued.          A modified ribbon cartridge containing error correction ribbon carries at least one abutment that engages a backspace coupled actuating mechanism upon removal of the ribbon cartridge.          Therefore, automatic backspacing of the typewriter carriage occurs after a modified ribbon cartridge is inserted into the typewriter to perform an error correction operation simply by removing the error correction ribbon cartridge.  Although a backspace function has been selected as the most appropriate function for actuation by the modified cartridge, other selected functions may also be actuated by the modified cartridge.

Abstract: ABSTRACT OF THE DISCLOSURE           FM signals within a predetermined bandwidth representing light-dark variations in a document are transmitted over a communications network to a facsimile receiver.  The FM signals are applied to differen-tiating and frequency doubling means so as to generate trigger signals with substantially equal amplitude and width for application to a single shot multivibrator.  Reset means coupled directly to the input of the single shot multivibrator are responsive to the trigger pulses to reset the single shot multivibrator to the astable state when the frequency of the trigger pulses is sufficiently high that trigger pulses occur while the multivibrator is in a previously initiated astable state.  An average DC voltage detector is connected to the output of the multivibrator such that the average DC voltage represents the ratio of the astable state duration to the stable state duration.

An annular array of similar permanent magnets of sequential opposite polarity is dis-posed on the surface of the core pole opposing the rotor blades in serial intervention in the coil flux path.  The rotor blades are sized and spaced circumferentially relative to the magnet pole faces parallel to the surface of relative movement, to pro-duce successive stable rest positions for the rotor, wherein each blade partially overlaps a different pair of adjacent magnet pole faces of opposite polarity; and, the rotor blades and magnet pole faces are of dissimilar shape selected to produce substantially in excess of half the angular rotation of the rotor between suc-cessive stable rest positions in the designed direction of rota-tion while resiting such rotation in the opposite direction, all upon the application of alternate positive and negative electrical pulses to the coil.
