Abstract: TIMER AND POWER CONTROL SYSTEM                     Abstract of Disclosure A timer system includes a power switch operable to power circuit closing and opening conditions, timing means for identifying various timing segments over a 24-hour period and marker storage means having respective power turn on and off marker storage locations assigned to the time intervals encompassing a 24-hour period.  An on-off push button or other on-off control operates the power switch and may act as an aid in setting the markers in the storage means.  The timer system may also include a rotatable present time setting dial, also adjustable to different positions representing the different time intervals, and a manually operable timer on-off setting member.  For real time programming, control means respond to normal operation of the on-off control during a first 24-hour period, initially to set said markers in the storage locations.  For fast programming, the control means responds to the successive advancement of said dial from a present time setting through said various positions and the selective operation of the push button or other on-off control to set the markers in the storage locations assigned to the time interval involved, which markers automatically control the operation of the power switch when the timer on-off setting member is in its timer-on position, except when overriden by operation of the on-off control.

Abstract: A B S T R A C T       A mixture which is used for the manufacture of electrodes and comprises dry material and electrode binding agent.  The mixture is prepared in a system which is at least in part dust and gas-tight and such that the mixture is simultaneously stirred up or fluidised, degassed and homogenised, and treated thermally.  In the course of such treatment further additions can be made to the mixture.  The described procedure takes place mainly in mixers operating continuously or discontinuously, various arrangements and designs of mixer being possible.  Fundamental to the thermal treatment is that the mixture can be cooled in a mixer such that the coolant vaporises completely during the mixing.  The thermal treatment is regulated by way of given operational parameters.

Abstract: TITLE OF THE INVENTION        A Thermal Printing System ABSTRACT OF THE DISCLOSURE         A thermal printing system having a plurality of thermal elements aligned on a straight line in the direction perpendicular to the moving direction of a thermal paper for printing characters on a dot matrix principle has been found.          Each thermal element is selectively energized by a power pulse according to the desired pattern to be printed, and the pulse width of said power pulse which is applied to a thermal element is controlled according to the moving speed of a thermal paper and/or the status (black/white) of the previously printed several dots so that the desired concentration or color density is obtained.  A digital memory which stores the status of the previously printed dots or the duration between the time that the last black dot is printed and the present time is provided, and according to that digital memory, the trigger pulse for initiating the power pulse for each thermal element is defined.  Thus, a thermal paper is always heated to a proper temperature to provide the desired printed concentration in spite of the change of the moving speed of a thermal paper and/or the status of the previously printed dots.          Then, the high speed printing and/or the variable speed printing is obtained.

Abstract: ABSTRACT         A freestanding  stair assembly which is simple and economical to produce and assemble is disclosed.  The assembly utilizes a plurality of interengagable tubular links each of which is provided with a pair of axially directed parallel slots in the annular wall.  The slots extend from one end of the link and are oriented and dimensioned so as to receive therein the other end of a superjacent link.  The links may be rotated relative to each other to achieve a linear or a non-linear stairway,  Each link is adapted to have a stair tread member secured thereto.  Also each main slot may be provided with a locking slot in the annular wall which is perpendicular to the main slot.  Each riser may than have a lower flange at the other end, which flange can engage with the locking slots as relative rotation of the risers is performed.  The circumferential extent of the lower flange is such that adjacent risers are locked together thereby at any reasonable relative angular orientation.  The uppermost and lowermost risers are adapted to be respectively secured to an upper support such as a joist, and a base support, such as a floor.  With the invention a spiral staircase, for example, may be achieved without requiring a central support pole.

Abstract: ABSTRACT OF THE DISCLOSURE     The isolation chamber (100) has an aluminum outer housing (106) with heat transfer fins (110L, 110D, 110R) extending therefrom on the outside vertical surfaces, and insulation material (114) mounted along each inside surface thereof forming a thermally insulative shell. Large aluminum studs (118L, 118R, 118D) extend inwardly from the side surfaces of the housing through the insulative shell for supporting a solid state heat pump (122). Each pump has a set of inwardly directed heat exchange fins (126). Each stud and associated pump and inwardly directed set of fins forms a heat conductive path between the surrounding ambient air and the interior of the isolation chamber for controlling the heat flow therebetween. The combined configuration of the inner heat exchange fins defines a central cavity (140) which is temperature controlled to within a desired operating temperature range. A card cage (130) containing the electronic devices is installed in the temperature regulated central region. The atmosphere within the central region is isolated from the surrounding ambient air, and supports internal convective heat transfer between the electronic devices and the inner fins by recirculating throughout the card cage and between the inner heat transfer fins. The operating level of the heat pumps are adjustable to provide the most efficient pumping as the external temperature varies. The outer housing and card cage form a double walled electrically conductive structure which twice encloses the electronic devices for providing double shielding from electrical interference. The card cage is cushioned from external vibration by the absorption affect of the insulative shell material.

First and second coatings of glass soot are deposited on the surface of the thin stratum to form a porous preform.   The refrac-tive  index of the soot particles of the first coating is greater than that of the soot of the second coating, and the soot of the first coating has a viscosity lower than that of the second coating   The mandrel is removed. and the soot preform is subjected to a high temperature whereby it is consolidated to form a dense glass blank.  The glass surface tension and the relative viscosities of the inner and outer portions of the preform cause the aperture to close during the consolidation process.  The thin stratum, which preferably include  P205, smoothes over the damage caused by removing the mandrel and reduces or even eliminates seed formation at the axis of the resultant glass blank.  The blank may be heated and drawn into a filament, or it may be sliced into optical windows, lenses or the like.
