Abstract: A BUILT-IN LINEARITY TESTING ARRANGEMENT    FOR AN FM RADIO SYSTEM by Abram Froese Larry Yasuo Qnotera Alvin Liebelt Abstract of Disclosure me baseband input to a frequency modulation radio transmitter is switchably connectable to a square-wave generator, the amplitude of the square-wave being adjusted to provide a predetermined deviation of the FM radio transmitter.  The output signal of a pilot oscillator is also applied to another baseband input of the transmitter and is subjected to amplitude modulation because of non-linearities which exist in the system and which adversely affect the signal during transmission through the system.  At the receiving end of the radio system, the receiver output comprises the pilot frequency and a superimposed amplitude modulated signal which are applied to a product detector.  The output of the product detector is a pulsating DC signal comprising a basic DC component, which is representative of the amplitude of the pilot frequency and an AC component, which is representative of the system non-linearity.  The pulsating DC signal is applied to one terminal of a capacitor.  The AC component appears at the other terminal and is rectified and integrated to obtain a DC signal, the amplitude of which is proportional to the slope component in the system non-linearity.  This DC signal is measured by a direct current meter.

Abstract: A B S T R A C T            Procedure for the manufacture of an artificial leg with a sleeve for the fixing of the artificial limb to the remaining part of the leg, in which the procedure embraces the manufacture of a positive model of the extremity which is used for forming the sleeve which is built into the artificial limb.            The purpose of the invention is to facilitate individual adaptation concerning the form of the sleeve so that total surface contact is achieved against the leg, and also to reduce the manual work and the risk of failure.            The invention is characterized by the sleeve being manufactured from an injection moulded standard sleeve of clear thermoplastic material with truncated conic form which forms an inner sleeve in the finished sleeve. The inner sleeve is roughly shaped after the model in heated condition and is tried on the leg, when any deviations in form and irregularities in contact pressure are established by visual inspection through the clear material of the inner sleeve, after which the shape is finally adjusted in one or more steps. When essentially total surface contact has been achieved the inner sleeve is strengthened externally by laminating and is built into the artificial limb.

Abstract: BILEVEL CODING OF COLOUR VIDEO SIGNALS     Abstract of the Disclosure Bilevel coding of colour video signals, for example video teleconference or NTSC broadcast television signals, is used to reduce the required storage capacity or transmission channel bandwidth.  Each multi-level or continuous tone picture element in a frame is compared to a threshold and assigned one of two values depending upon whether or not it exceeds the threshold value.  The threshold is produced by averaging the luminance components of neighbouring picture elements and constraining the average by a signal derived from the chrominance of the original video signal.  A significant feature is that the use of the chrominance signal in this way obviates the need, common to known monochrome systems, of adding noise (or dither signal) to the signal with concomitant picture degrading artifacts.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention is in the field of graded-index optics and particularly relates to a singlet graded-index lens useful as a microscopic objective for video-disk lens pickup systems or the like.  For applications such as video-disk lenses, it is important that the lens exhibit very low monochromatic aberrations, particularly low spherical aberration, while at the same time being inexpensive.  The present specification provides a spherical singlet lens exhibiting the required low aberration.  Thus the specification provides a singlet lens including opposing first and second refracting surfaces having spherical curvatures C1 and C2, respectively, and a radial refractive index gradient wherein the refractive index N of the lens varies with radial distance r from the optical axis of the lens approximately according to the power series expansion formula:               N(r) = N00 + N10r2 + N20r4 wherein adjustment of the third-order spherical aberration of the lens to a value of about zero is effected by selective adjustment of the power series coefficient N20, wherein adjust-ment of the third order coma of the lens to a value of about zero is effected by selective adjustment of the curvature of the first refracting surface C1, wherein the remaining aberra-tions of the lens are sufficiently reduced that the lens exhibits an rms optical path difference not exceeding about .lambda./2 throughout the entire image field, and wherein the power series coefficient N10 and the curvature of the second refracting surface C2 are selected such that the lens exhibits an rms optical path difference not exceeding about .lambda./13 at field heights below 0.7.

Abstract: PAPER HOLE DETECTING APPARATUS                 ABSTRACT OF THE DISCLOSURE    An apparatus for detecting a feeding of paper has a reflector which is mounted on a bottom of a switch lever.  The switch lever, in turn, is slidably mounted on a black paper retainer plate which has poor re-flecting  properties,  and  a  light  emitting  element emits light which is reflected by the paper towards a light receiving element.  When paper which has good reflecting properties is being fed,  the reflector is slid so that it is no longer located opposite the light emitting element, and any light passing through holes in the paper is thus poorly reflected by the black paper retainer plate, thereby enabling the light receiving element to readily detect the presence or absence of a hole in the paper.  However, when the paper being fed has poor reflecting properties, the reflector is slid so that it is located opposite the light emitting element, and any light passing through one of the holes in the paper is strongly reflected by the reflector.  Therefore, again, the light receiving element can readily detect the presence or absence of the holes.

Abstract: ABSTRACT           A method and apparatus for intensifying contrast during the recording of masters in electronic image processing wherein a master is scanned opto-electronically and an image signal is produced as well as two unsharp masking signals by scanning a first unsharp masking area and an enlarged second unsharp masking area around the current image point.  Differential signals are generated from the image signal and each of the two unsharp masking signals and the two differential signals thus formed are mixed together in a selected ratio.  The mixed signal is divided into positive and negative correction components which can be differently amplified and after comparison to threshold signals are combined to form a correction signal which has an effective width which depends on the mixing ratio.  The mixing ratio may for example, be dependent on the gradient and/or the contrast of a master contour.  The correction signal thus formed is then superimposed on the image signal so as to provide contrasted intensification and the contrast enhancement can be matched to the properties of the master by controlling the effective width of the correction signal.
