Abstract: INVENTORS              Harley Burke LINDEMANN   John Boyden GOODELL                         TITLE; OPTICAL AIR LENS SYSTEM     ABSTRACT OF THE DISCLOSURE      In an optical system the use of one or a plurality of air lenses set in an optical  medium of higher refractive index than air at a predetermined distance from an object such that various optical aberrations are minimized or eliminated by using aplanatic optical surfaces.  Refraction occurs only for a ray going from the higher to the lower refractive index medium.  Rays entering the higher refractive index medium from the lower are never refracted since the optical surface is always chosen to have its center of radius coincident with the  object or image being optically operated on by the lens. The system can be used to magnify the image of an object, the object being most any two-dimensional representation such as a negative or a positive print.  The object might alternatively be a light source or an external object whose rays are imaged onto an embedded light sensor so that the functions of the source or sensor respectively can be enhanced by the optical system.

Abstract: Abstract:            An improved case for a self-extending rule having a resilient blade which assumes a straight position when in a relaxed state and has a pair of case sections formed with flat top, bottom, and back walls, and arcuate side walls enclosing a cylindrical interior chamber and with a front wall having a generally arcuate opening in a lower sector thereof defined by the rim of the adjacent side wall and the edge of a reen-trant web extending from the opposite side wall.  The under-side of the web has a center post extending into the chamber to mount a cylindrical cup for nesting the convolutions of the blade when inserted endwise through said arcuate opening and underneath the edge of the web.  A brake is mounted for rec-tilinear movement in a radial opening in the top wall of the case adjacent the front side of the cup and is biased into en-gagement with a converging open rim of the cup.  The back of the case is spaced from the bottom of the cup and forms an annular chamber in which pivotal weights are mounted to ro-tate with the cup and engage the annular wall of the chamber for limiting the speed of rotation of the cup.

There is a spacing between the core and the second helical spring.          The bristles can thus flex to facilitate reversal of the brushing movement without strenuous effort while the brush is still within a flue, even if the length of the bristles is considerably in excess of the diameter required for cleaning the flue.

Abstract: METHOD OF MAKING INELASTICALLY COMPRESSIBLE DUCTILE PARTICULATE MATERIAL ARTICILE AND SUBSEQUENT         WORKING THEREOF            ABSTRACT OF THE DISCLOSURE           Ductility is controlled by controlling the size of the particles of particulate material and/or the degree of sphericity of the particles, the smaller and/or more spherical the particles, the greater the ductility of the material. The material has preferably spherical pores, pre-ferably hermetic, with a controlled ratio of pore volume to material volume to provide the property of compressibility.          The particulate material itself must have the capability of becoming ductile.  The ratio of pore volume to total volume of the material is controlled by particle size, sint-ering profile the property of the material and the initial volume loading of the pre-sintered part (i.e. the ratio of binder to particulate material).  Some materials which are not ductile in and of themselves can be formed into ductile and/or compressible materials in accordance with the system of the present invention,  This material can then be formed into a predetermined shape with subsequent binder removal and sintering in accordance with prior art methods except that the sintering profile may be controlled, if necessary, as one means of controlling the desire porosity of the part.     Materials as described above can be formed by in-elastic compression techniques since the articles are compres-sible due to the voids, the compressed material retaining its compressed shape.  This can be provided by the well known coining, hot isotatic pressing techniques and other well known techniques,  Precision parts with densities approaching theoreticl maximum density for the material involved can be preformed using these techniques.   In accordance with this method, a part is formed and sintered having a shape which is substantially the same as the final shape desired but of slightly larger dimension.  This article is then placed in a forming die cavity and compressed according to the contour-of the die.  unlike conventional materials, the form will compress to the shape of the die with great accuracy.  It is necessary, of course, that the degree of compression in the forming machine in volumetric terms be the same as or less than the volumetric content of the pores within the body to be formed.  In this way precision parts can be formed to predetermined substantially exact dimension with substantially no flash.

The gate electrode of the first IGFET is used as a first input terminal of the differential amplifier and the gate electrode of the second IGFET is used as a second input terminal of the differential amplifier. This amplifier has an output terminal for deriving an output signal in response to a potential difference between the first and second input terminals, and also has an input offset corresponding to the difference of threshold voltages. The first input terminal of the amplifier has the voltage of the battery applied thereto. The second input terminal of the amplifier has a reference potential applied thereto, whereby an output signal in response to a potential difference between the battery voltage and said input offset of the amplifier is derived at its output terminal.
