Abstract: ABSTRACT      A down-hole drilling apparatus having a drill tool assembly with a cutting head at one end connected to an umbilical which extends to a retrieval reel on the surface.  The umbilical provides electrical power, drilling fluid and means for instrumentation and control signals to be transmitted between the drill tool assembly and a processing device on the surface.  The drill tool assembly can propel itself into or out of a bore hole by the cyclical actuation of anchor and ram units or change the direction of drilling by actuation of thruster assemblies in response to control signals sent manually by an operator or automatically by the processing device.

Abstract: ABSTRACT     A musical instrument is disclosed in which light beams striking a detector produce various tones and the loudness of the sounds produced is dependent upon the intensity of the light beam which can be changed by interrupting the beam or reflecting the light backwards to a detector situated next to the light source.  A special amplifier circuit is provided which responds to both the amount of light beam interruption as well as the rapidity of interruption.  The invention can be variously embodied in woodwind, string and percussion instruments and can also be used on a stage and controlled by moving dancers or musicians.

Abstract: ABSTRACT   An energy efficient thermoremanent magnetic imaging method and apparatus comprising a moving magnetic recording medium which is passed through a nip formed by a thermal printhead and a pressure roller, so that the magnetizable surface of the recording medium is in pressure contact with the heating elements of the thermal printhead. The recording medium is pre-magnetized prior to entry in the nip and passed through a magnetic field of lower strength and opposite polarity at the nip. Small areas or pixels of the pre-magnetized recording medium are heated by the thermal printhead in image configuration and allowed to cool in the presence of the magnetic field at the nip. The magnetic poles of the imagewise pixels are switched, forming fringe fields between the pixels and pre-magnetized background areas. The pixels with the switched magnetic poles are spaced from each other to prevent the fringe fields from forming around the periphery of clusters of pixels and collapsing inbetween some or all of the pixels making up the cluster.

Abstract: ABSTRACT OF THE DISCLOSURE   SYSTEM FOR OPERATING A DOT MATRIX          DISPLAY PANEL TO PREVENT CROSSTALK     The disclosure is of a system for operating a dot matrix display panel including elongated anodes and cathodes oriented transversely to each other to define columns of D.C. scanning cells.  An array of quasi A.C. display cells is provided spaced from the D.C. scan cells by an apertured electrode plate.  Operation of the D.C. scan cells to transfer glow from a scan cell to an associated display cell is achieved by momentarily turning off the scan cell by the application of a negative pulse to its anode.  To prevent the coupling of this pulse to adjacent anodes and spurious operation of adjacent scan cells and display cells, a counter-balancing positive pulse is applied to all anodes and a counter-balancing negative pulse is applied to all "off" cathodes.
