Abstract: RETRO-REFLECTING SHEET MATERIAL          Abstract of the Disclosure The specification relates to retro-reflectors of the type used for road signs and markers and vehicle licence plates to make these objects more noticeable to road users after dark.  In the invention, the surface of a metal substrate is made retro-reflective by applying a layer of an organic polymeric material and adhering glass beads thereto, and then passing the substrate through a roller mill or the like with the glass beads covered by a platen so that the beads form indentations in the metal surface.          The presence of the platen allows the pressing (indentation) step to take place without damage to the glass beads or to the layer between the beads and the metal surface.  By this means, a hard metal article can be made directly retro-reflective.

Abstract: SECTORIZED DATA PATH FOLLOWING SERVO SYSTEM                                  Abstract A servo system for accurately positioning a transducer relative to data paths on a recording medium by detecting sync and servo signals from two parallel abutting servo tracks sharing a common longitudinal boundary within circumferentially spaced sectors of the medium. Within each sector of the recording medium, two servo waveforms of different frequencies in two abutting servo tracks are preceded by a sync reference waveform of the same frequency in both servo tracks which is used as a reference for a phase locked oscillator, connected to the transducer, generating a pair of mudulation signals that are to be mixed with transducer signals from both servo waveforms. A pair of servo channels are provided for receiving the pair of modulation signals and the servo signals for deriving an imbalance error signal representing deviation of the transducer from the center line of a data path, which is the projection from the sectors of the common longitudinal boundary between servo tracks. The imbalance error signal is used to center the transducer on the data path.

Abstract: ABSTRACT OF THE DISCLOSURE          A reusable integrated cathode unit and an associated electrolytic method are disclosed for the simultaneous production of a multiplicity of metal electrodeposits by plating from a base metal electrolyte.  The rigid cathode unit has two integrated components, a slab of non-conductive material and a metal assembly which is embedded therein. The metal assembly has projections that penetrate the slab surface at spaced locations thereby forming an array of conductive metal islands flush with or raised above the surface of the cathode unit which serve as the sites for plating of the electro-deposits.  The method is advantageously characterized by the production of unique, crown shaped electrodeposits with basal areas much larger than the areas of the conductive islands on which they are formed, and a significant component of growth in a direction normal to the plating surface.  Following a single electrodeposition cycle, the electrodeposits are readily recovered from the cathode unit, the latter being recycled to the electrolytic operation.  The sequence is repeated many times, without interruption for repair, as a result of the rugged physical properties of the cathode unit which provide for an extremely long service life.

Abstract: RCA 74,082 ABSTRACT OF THE DISCLOSURE First and second capacitors are charged from a DC source of unregulated input voltage through the primary winding of a flyback transformer of a horizontal deflection circuit.  The average voltage across the first capacitor is established as the voltage difference between the input voltage and the average voltage across the second capacitor. The first capacitor functions as a trace capacitor for a horizontal deflection winding.  A switch applies a trace voltage to the horizontal deflection winding to generate a trace deflection current.  The switch also applies the voltages developed across the second capacitor and across a flyback transformer secondary winding to a regulator inductance to control the flow of current in the second capacitor.  The current flowing through the inductance is varied in order to control the voltage across the second capacitor for regulating a selected deflection circuit quantity.
