Abstract: Abstract An apparatus codes a scanned document locally representing each graphic element within a prescribed measure of accuracy by a trapezoidal approximation.  The invention also includes a method for similarly coding a scanned document.  The apparatus determines whether each scanned run is indicative of a .gamma.- or .lambda. -junction, the termination of an old, or the commencement of a new graphic element, and whether a new linear approximation is necessary.  The invention in a preferred embodiment recognizes symbols by determining the center of mass and maximum extremity of a symbol candidate, and comparing it to a reference library after normalizing with respect to scale, orientation and center of mass.  In a preferred embodiment, an adaptive threshold parameter governs coding so as to reject noise and optimize a pair of linear predicters in a small number of scans.  In a further preferred embodiment the accuracy of the linear predicters is refined so that the error is exponentially bounded.

The record player also comprises a pivotable pres-sure lever (24) with a pressure member (29) for urging the disk against the turntable. The drawer (6) has side walls (9, 10) in which are formed grooves (14) in which the platform (15) is movable between an upper position and a lower position with respect to the drawing, the platform (15) being located below the level of the upper side in the turntable (21) when in the lower position. During a first part of the inward movement of the drawer the platform (15) is held in the upper position in the grooves by at least one positioning member (17), and during a second part of the inward movement is pressed against at least one stop (26), as a result of which the platform performs a substantially vertical movement in the grooves (14) to the lower position with respect to the turntable (21). The pressure lever (24) is engaged with the platform (15) during this movement of the platform (14) and is pivoted thereby in the downward direction.          Fig. 1.

Abstract: ABSTRACT OF THE DISCLOSURE    A microwave oscillator and a combination microwave oscillator/single balanced mixer for a satellite television receiver includes a cylindrical dielectric resonator located on one side of a ground plane formed by a conductive foil on a substrate with microstrip transmission lines formed by foil patterns on the opposite side of said substrate.  gallium arsenide FET is disposed in a hole through said substrate with its source electrode connected to the ground plane and its drain and gate electrodes coupled to first and second transmission line strips portions of which are following the contours of said dielectric resonator.  Two sets of coupling slots are formed in the ground plane for permitting magnetic coupling between the dielectric resonator and the opposite transmission line strips.  In one embodiment an additional coupling slot in the ground plane couples the dielectric resonator to an output transmission line strip.  In another embodiment a dual diode package is disposed in a square hole in the substrate and ground plane with the common junction of the two diodes being coupled to a third transmission line strip and the opposite ends of the series connected diodes coupled to the ground plane.  Coupled magnetic energy from the resonator creates a potential difference across the ground plane at the opposite sides of the square hole thus generating a local oscillator signal across the series connected diodes.  The third transmission line strip serves as a coupling for both an RF signal input to and an IF signal output from, the mixer.

Abstract: ILLUMINATED SPIRIT LEVEL            ABSTRACT OF THE DISCLOSURE     An illuminated spirit level comprises a bubble tube mounted in a support body with light source shielded to define two light paths directed through the bubble tube to apertures on the outside of the support body so that with the bubble positioned centrally the light is communi-cated directly from the light source through the bubble tube to the apertures.  On movement of the bubble relative to the bubble tube caused by inclination of the spirit level, the bubble intercepts one of the light paths so as to cause refraction directing the light away from the aperture.  The different refraction is caused by the dif-ference in shape between the lower surfaces of the bubble and the upper surface of the bubble tube.  The curvature of the bubble causes the edge to totally reflect the light path to divert the light.

Abstract: Abstract of the Disclosure The invention describes a method and an apparatus for the acoustic counting of individual particles, more particularly particles of seed material to be sown whereby, by comparison of the vibratory signals actually received as a result of grains impinging upon a sound transducer having pre-determined characteristic vibratory signals, it is determined whether a signal pattern typical of one grain or of another grain is present.  Individual particles are thus counted and this permits relatively accurate detection thereof.  The apparatus for the implementation of the method consists essentially of an evaluating circuit in which characteristic signal curves are stored, with which the signal curves actually detected are compared.  The number of particles actually impinging are also determined from this comparison.
