Abstract: INLEAD AND METHOD OF MAKING A DISCHARGE LAMP ABSTRACT OF THE DISCLOSURE An inlead for an electrode sealed into a quartz arc tube has a foil portion which is stiffened by reversely folded lateral edges.  The folded edges overlap a tapering region of greater stiffness where the foil portion joins end portions of the inlead.  In making a discharge lamp, the electrode-inlead assembly is self-centering as a result of making the overall width of the foil portion and its folded edges exceed slightly the internal diameter of the quartz tube.  The frictional engagement between the folded edges and the inside wall of the tube retains the electrode-inlead assembly while the tube is heat-collapsed onto the foil portion to seal the electrode-inlead assembly in place.

Abstract: ABSTRACT OF THE DISCLOSURE        A steam generator of the type comprising two combustion chambers separated by a partition.  The walls of the chambers and the partition is formed by a tubing system so arranged that the working medium flows first through the partition and therefrom through the walls of the chambers.  A steam separator is disposed at the outlet of the partition.  The water discharge of the separator communicates with the input of the chamber walls.  The steam outlet of the partition bypasses the walls and communicates with a superheater.  The invention increases uniformity of heat distribution in the walls of the chambers, eliminates the need for a second feed control system required in a known parallel system and increases boiler efficiency as the total pressure drop can be reduced at full load.

Abstract: ULTRA HIGH RESOLUTION JOSEPHSON SAMPLING TECHNIQUE.             ABSTRACT     A circuit is provided for sampling and accurately reproducing unknown signals with picosecond resolution, which could be electrical, optical, x-ray, gamma ray, or a particle signal.  The circuit comprises a super-conductive monitor gate having at least two states which are distinguishable from one another.  The monitor gate could be, for example, comprised of a Josephson device or a superconducting quantum interference device (SQUID). Switching means, including a source of the unknown signal, are provided to switch the state of the monitor gate.  This switching means includes a sampling pulse source and a bias current source which are combined with the unknown signal to change the state of the monitor gate.  A noise elimination means is also provided including a lock-in amplifier, a comparator, and a feedback loop.  A time averaging technique eliminates any incorrect indications resulting from noise. A timing means establishes a timing reference and sampling delay, and includes the sampling pulse source, delay lines, and a trigger pulse source connected to the source of the unknown signal and to the sampling pulse source.  A display, such as an x-y recorder or oscilloscope, indicates the unknown signal.  The circuit has applications in all devices where fast unknown waveform must be measured exactly, and in the field of non-equilibrium and superconductivity, where exceptionally high resolution and sensitivity are required.

Abstract: ABSTRACT            TITLE:  RANDOM ACTION TOY     A toy has a housing on which are located a plura-lity of individual operator buttons.  These slide from a first position to a second position.  The toy further includes an indicator member which moves from a nonindi-cating position where the indicator member is located inside of the toy to an indicating position wherein a portion of the indicator member is located outside of the toy.  Movement of the indicator member from its position inside the toy to its position outside of the toy is accomplished by movement of one of the buttons.          The toy further includes a control mechanism which couples only one of the buttons at a time in a seemingly random manner to the indicator member.  After the con-trol mechanism which couples only one of the buttons at a time in a seemingly random manner to the indica-tor member.  After the control mechanism is set, the player or players of the game systematically or hap-hazardly, as may be the case, move the buttons attempt-ing to discover which of the buttons controls the indi-cator member.  When the proper button is moved the indi-cator member moves to the indicating position.  After successfully choosing the right button, the control mechanism is then reset to change which of the operator buttons controls the indicator member.  This resetting is done in a seemingly random manner and when the game resumes once again the operator must find the correct button.
