Abstract: Abstract of the Disclosure A mechanism for tensioning a cable or chain over a load and for maintaining such tension even though the load may shift and settle.  The mechanism includes a "U" shaped base ??at rotat-ably mounts an elongated cylindrical hollow spool.  The spool is connected at opposite ends to a spaced pair of ratchet wheels. Pawls are located on the base member for operatively engaging each of the ratchet wheels.  Inside the hollow spool is a torsion spring that is directly connected at one end to the spool.  The remaining spring end is connected to one of the ratchet wheels.  The spool and this particular ratchet wheel are relatively movable about the longitudinal spool axis since they are interconnected only through the torsion spring.  The remaining ratchet wheel is affixed directly to the spool for rotation therewith.  Turning the spool through this ratchet assembly does not wind the spring but instead serves only to wrap the cable or chain about the spool circumference. Once the desired tension has been applied to the cable or chain, the spring may be tightened by turning the other ratchet wheel. Thus, tensioning or winding of the spring may be accomplished as a function separate from the initial cable tightening function.

Abstract: OPTICAL RESONANCE PUMPED TRANSFER LASER WITH HIGH MULTILINE PHOTON-TO-SINGLE-LINE PHOTON CONVERSION EFFICIENCY     ABSTRACT OF THE DISCLOSURE     Lasers are disclosed wherein trapped multiline laser radiation from a DP laser is employed to pump a DP-CO2 working gas mixture within the optical resonator for the DE laser.  The multiline pumping energy is resonantly absorbed by the DP component of the working gas mixture and collisionally transferred to upper energy levels of lasing transitions in CO2.  A narrow-band optical resonator disposed about the working gas interaction region with the pumping radiation and tuned to a desired CO2 transition enables a single line laser output to be obtained on the desired transition.

Abstract: ABSTRACT         Head end apparatus delivers video signals, e.g., premium and standard television programming to distinct locations such as hotel/motel rooms, an apartment or the like via a common MATV cable.  The head end also transmits digital massages to receivers at each room location which are re-covered via a phase detector and supplied to predetermined appropriate out-put utilization apparatus via a multiplexer and microprocessor.  Similarly, messages generated at each room are transmitted upstream to the head end via the cable, employing a portion of the phase detector apparatus.  In ac-cordance with varying aspects of the present invention, the bilaterally propagating digital messages may comprise status controls for controlled equipment, e.g., electrical loads; and/or may comprise a data exchange for a communications application.  Further, the room transmission apparatus is adapted to fail, if at all, in a noninterfering mode which does not com-prise overall system operability.

Abstract: ?I-7299 AIR RELEASE CONTROL IN SEISMIC ENERGY SOURCE AIR GUN         ABSTRACT OF THE DISCLOSURE     Disclosed is a seismic source device, known in the industry as an air gun, having shuttle control for allowing a predetermined discharge of compressed air into water for purposes of seismic exploration.  The shuttle is controlled by secondary shuttle means for closing the exhaust ports before all of the compressed air in the firing chamber of the air gun is exhausted.      This point of closing the exhaust ports before virtually all of the compressed air is discharged differs from prior art air guns.  By preventing further discharge of air, secondary pulses are greatly reduced, thereby enhancing the operation of the entire system.  Further, by preventing all the air in the firing chamber from being discharged, the system becomes more efficient and more cost effective.
