Abstract: ABSTRACT OF THE DISCLOSURE             A two beam alternating light colorimeter is dis-closed wherein a light beam passing through a lens system having a shutter is periodically deflected by a pivoting mirror.  In a first non-deflecting position of the pivotable mirror a first measuring beam is created which passes through a first measuring cell and is guided to a common photo cell.  In a second deflect-ing position of the mirror a second measuring beam is created which is guided through a second measuring cell to the same photo cell.  Signals from the photo cell are connected through a controlled switching element to an analog memory.  A computing circuit is provided which connects to an output of the analog memory and also to the photo cell.  The switching element connects the first measuring signal to the analog memory when the mirror is in a non-deflecting position and opens when 'he mirror is in a deflecting position.  The computing circuit compares the signals corresponding to the first and second measuring beams.

Abstract: PRODUCTION OF TRITIUM                         ABSTRACT        Tritium and electricity are co-generated in an HTGR.  Nuclear fuel material and target particles are disposed in chambers formed in a body of refractory material, such as graphite.  The target particles comprise minute cores of a solid lithium compound, e.g., LiA1O2, an inner coating of porous material and an outer gas-tight coating of relatively dense material. Irradiation of the target particles by thermal neutrons results in transmutation of Li6 nuclides to create helium and tritium that is retained within said outer gas-tight coating, which preferably includes a relatively thick layer of SiC or ZrC.  Tritium is recovered by heating the irradiated target particles to a fairly high temperature or by crushing the SiC or ZrC coating layers.

Abstract: ABSTRACT    An electronic tennis game having a display panel with ball segments which are illuminated in different sequences to simulate a tennis ball which can move from one side of the tennis court to the other along different trajectories.  Player elements are provided on each side of the display panel at positions which intercept the trajectories, each player element including a body portion and racket segments which can be sequentially illum-inated to simulate a tennis player swinging his racket.  Corres-ponding to each player element is a volley button.  A game operator attempts to ascertain the trajectory of an approaching ball and depress the volley button corresponding to a player element positioned to intercept it.  If the volley button is depressed at the right time, the sequentially illuminated racket segments of the selected player element appear to hit the ball back to the other side of the tennis court.

Abstract: Abstract of the Disclosure An improved heating apparatus, for example for use as a wood or coal burning parlor stove and providing a significant heat output, has a construction for reducing thermally induced mechanical stress and for enabling the interior baffle assembly components of the apparatus to be removed therefrom, for replacement if necessary, without dismantling the apparatus exterior frame.  The elements of the interior baffle assembly are interconnecting and are secured in a mechanically stable configuration by single point connection to the apparatus frame.  The apparatus can have primary and secondary combustion chambers and a baffle system for directing flue gases along a circuitous path from the secondary combustion chamber to an exit aperture whereby a significant proportion of the heat of said gases is given up to the apparatus.  A vertically oriented downwardly directed two component baffle separates the combustion chambers.  A vertically directed, two component fireback separates the primary combustion chamber from the circuitous path.  First and second air paths supply air to the primary and secondary combustion chambers respectively.  The air provided by the supply conduits to the respective combustion chambers is preheated and the air provided through the second path promotes secondary combustion of the flue gases to thereby increase the overall efficiency of the stove.

Abstract: ABSTRACT OF THE DISCLOSURE         A manually manipulatable device for adjusting the position of a workpiece supported on a machine having relatively movable parts operated by electrically controlled, selectively energizable and deenergizable driving means comprises an elongate arm having a workpiece engageable fork at one end and a support at its other end for manipulation by an operator.  The support preferably is pistol-shaped having a grip at one end and a barrel at its other end.          The support includes two normally open, manually closable electrical switches in circuit with the machine's driving means to effect energization of the latter under the control of a workpiece manipulating device, but only when both of the switches are closed.  The switches are spaced apart from one another a distance greater than that which can be spanned by the fingers of one hand of the operator, thereby preventing closing of both switches unless the operator's hands are on the support.  The workpiece engageable fork and the support are spaced apart a distance sufficient to ensure that, when the fork engages the workpiece, the support is spaced from the machine a distance sufficient to ensure that the machine operator's hands are outside the machine.
