Abstract: ABSTRACT OF THE DISCLOSURE   An eyeglass temple including a pair of telescopic temple members, the inner telescopic member having a longitudinal opening, and the outer telescopic member having a projection entering the opening for relative movement therealong upon telescoping of the members, the opening and projection being configured for retaining engagement with each other at selected positions of telescopic movement to maintain a desired adjustment.  The invention is relatively simple in construct-ion and avoids the necessity for complex and expensive components, which have tended to characterize prior art adjustable temples.  Also, the invention provides a durable and reliable construction and also provides for ready adjustability by comparison with prior art arrangements.

Abstract: PRIORITY MIXER CONTROL          Abstract of the Disclosure A priority mixer control for a multi-microphone audio system which limits access of individual microphones to the system output without the imposition of a fixed entry threshold; the control comprises a threshold signal generator that develops a D.C. threshold signal starting at a maximum level for a time T1 and then decreasing in amplitude as a function of time.  Each microphone channel is provided with a control channel including a comparator that compares the microphone signal, as an A.C. signal, with the threshold signal, and that switches the microphone channel to "on" condition when the microphone signal exceeds the threshold; all of the control channels are coupled to a threshold signal restoration means that drives the threshold signal back to its maximum level each time an audio channel is switched "on".          An audio channel that has been switched "on" remains "on" for a time T2 substantially longer than the time T1.  The number of channels currently in "on" condition is continuously monitored and the output gain is reduced whenever two or more channels are in "on" condition.

Abstract: The disclosure relates to a modular form of solar energy collector apparatus in which several double-wall glass tube collectors, each with vacuum jacket, depend from opposite sides of an elongated manifold.  The manifold includes split halves of foamed polymer insulation and rigid fiberglass reinforced skin thereon, assembled about closed-looped, serpentine liquid carrying tubes preferably of metal or glass in U-tube configurations depending from the manifold halves and extending into the larger double-walled glass tubes, the serpentine tube being connected, respectively, into inlet and outlet header pipes. The interior chamber of the collector tubes is closed by the manifold, thereby enclosing a part of each U-tube branch of the serpentine in a non-turbulent air space.  Solar energy collected on the absorber surface of the inner glass tube wall is transmitted to the U-tube and liquid therein.  The U-tube within the collectors is blackened and non-reflecting.  Principal heat transfer from absorber to U-tube is by radiation with some conduction and convection transfer.  The heat transfer liquid is entirely within a closed circuit, which avoids leaks, reduces weight, and cycle time of the liquid is reduced to a fraction of other liquid systems. The manifold and tubes are fastened to a support structure of novel construction enabling fabrication as a module and mounting on a solar exposure of a structure such as a roof, wall or frame.  Several modules are interconnectable to desired capacity for a particular solar powered heating or cooling system.

Abstract: Inventor:  Hugh Gibson Lawford ETHANOL PRODUCTION BY HIGH PERFORMANCE BACTERIAL FERMENTATION            ABSTRACT           The present invention is directed to the preparation of ethanol by bacterial fermentation.  It makes use of a micro-organism capable of producing ethanol and the process is car-ried out in two stages.  In the first stage a bacterial cell suspension is produced together with ethanol in an ethanol con-centration range that does not substantially inhibit produc-tion of the bacterial cells in a medium containing a source of nitrogen and a source of carbon.  Ethanol is then produced in the absence of substantial bacterial cell production by the addition of fermentable sugar to the bacterial cell sus-pension which is produced in the first stage.  The preferred microorganism is a member of the genus Zymomonas.
