Abstract: IMPROVED CHUCK ASSEMBLY AND COLLET          Abstract of the Disclosure The chuck assembly and the collet for retaining an end mill tool against axial pullout.  The collet includes a  radially  compressible  body  having  a  tapered  outer surface, a central bore and a radial aperture extending from the outer surface into the central bore.  The radial aperture has an undercut or larger diameter medial portion with a movable pin mounted therein, said pin being movably mounted and, adapted to extend into the bore to retain the tool.  The pin has a hole drilled through with a spring bar mounted  therein.    The  ends  of  the  spring  bar  are compressed to a length smaller than the diameter of the radial aperture and  inserted  into the larger undercut portions where the expansion of the spring bar retains the pin.  The hole in the pin is larger than the diameter of the spring bar to allow the pin to move along its axis (radially  into the collet bar).   The pin has a lower chamfered end which is urged inwardly into the bore as the collet  is  tightened  in  the  chuck  assembly  with  the chamfered end engaging a rear bevel end on a flat surface on the tool to secure the tool within the collet, and whereby the pin can move outwardly to release the tool when the collet is removed Prom the chuck assembly.

Abstract: SUSPENDED SOLIDS EXTRACTION      SYSTEM AND METHOD         Abstract Of The Disclosure A liquid containing suspended solids is first passed through an electrostatic treater, having no current flow across its electrodes, to initiate nucleation and coagulation of the particles.  Thereafter, it passes through an electrolytic treater wherein current may flow between the electrodes to further encourage coagulation to such an extent that flocculation begins.  The residual effects of the electrostatic treater prevent plating out on the electrodes of the electrolytic treater such that elec-trolysis can occur without sacrificing an electrode, and the electrodes are so arranged that the liquid passes sequentially through groups of concentrated lines of force whose repetitious, powerful action further encourages floc-culation.  From the electrolytic treater, the liquid with its flocculated material is delivered into a clarifying basin so designed that the floc will settle out and be removed from the basin with a minimum of manipulation because of the tendency of such material to immediately dissipate and disperse when handled while still in the liquid.

Abstract: D-22,344 BASEBAND SPECTRUM GENERATOR USING LOGIC                     LEVEL INPUT PULSES   by Lawrence E. Getgen ABSTRACT OF THE DISCLOSURE     A pulse source provides logic level pulses, having a pulse rate of fb and a pulse width of t', to the input of a switching amplifier having an open collector output.  A relatively high voltage, greater than the logic level voltage amplitude, is applied to the collector via a current limiting resistor R and the primary winding of a transformer.  The logic level pulses switch the switching amplifier on at intervals of T = l/fb for a duration of t' seconds.  The switching current in the primary winding of the transformer induces a current in the secondary winding thereof which has a spectrum that includes a spectral element at the switching rate fb and multiples thereof.  This output spectrum and power level depend upon the pulse amplitude and the pulse width t'.  The output power is proportional to the amplitude of the switched pulse and the pulse width t', whereas, the spectral bandwidth is inversely proportional to t'.

Abstract: ABSTRACT OF THE DISCLOSURE A novel burner, e.g. for a gaseous fuel is provided herein.  The burner includes a combustion nozzle housing having an axial gaseous fuel inlet and a plurality of radial combustion-supporting gas inlets and an axial nozzle.  The burner also includes a novel self-cooling shield having a pair of spaced-apart inner and outer concentric unapertured tubular mem-bers secured to, and projecting from, the forward end of the nozzle housing, providing an axially extending annular chamber therebetween, the annular chamber having an open forward end and communicating with a radially extend-ing closed ended rear annular zone, the outer tubular member being open at its forward end, and closed at its rear end, and the inner tubular member being open at both its forward end and  its rear end, the inner tubular member extending axially outwardly beyond the forward end of the outer tubular member, whereby cooling air is drawn in laminar flow into the annular chamber from the open end thereof to the rear annular zone and is expelled along with hot gaseous products of combustion through the inner tubular member.  Thus cooling air is drawn in laminar flow into the annular chamber and is expelled along with the hot gaseous products of combustion through the inner tubular member.  As well, preheated combustion-supporting gas (e.g. air) is admitted to the air inlets after passing rearwardly with-in the annular chamber.  Thus the torch not only is a self-cooling, hand-held, propane torch, but also the combustion is more efficient because of the preheating of the air.

The ventilator has a valve seat, a valve body, means for connecting the ventilator to an exterior air duct and operating means for resetting the position of the valve body.  Stationary support elements carry the valve body via a coupling of the kind which, on repeated operating impulses from the operating means alternatingly takes the valve body to an outer position and returns it to an inner position relative to the valve seat.  Both these positions are so selected that the inner one corresponds to the minimum demand for ventilation of an empty room while the outer one corres-ponds to the demand for ventilation with projected use by persons of the room.

Abstract: METHOD OF CONTROLLING THE INDEX PROFILE OF OPTICAL FIBER PREFORMS          Abstract of the Disclosure The refractive index profile of an optical fiber preform is controlled during manufacture by illuminating the gaseous precursor being fed to the preform substrate tube with ultraviolet radiation, measuring the intensity of either the uv that traverses the gas or the induced fluorescence, comparing this measurement with a reference signal, generating an error signal, in response to this comparison, and controlling composition of the gaseous precursor in response to said error signal.  A similar technique can be used to control the thickness and refractive index of each layer deposited upon the substrate tube by forming an x-ray shadowgraph of the layers as they are deposited and comparing the shadowgraph characteristics with appropriate reference signals to form a second set of error signals.  The latter are then used to fine tune the fabrication process.  The invention can also be employed in conjunction with the vapor axial deposition method of fabricating preforms.
