Abstract: A device for detecting the degree of deterioration of bank notes has a driving rotary body and a detection rotary body, which are a pair of oppositely disposed rollers each having alternately disposed enlarged diameter portions and annular grooves. These enlarged portions and the grooves of the two rotary bodies are in staggered, opposed relationship so that when a bank note is conveyed between the two rotary bodies, the note is deformed into a wave shape. The rotation of the driving rotary body influences the rotary movement of the detection rotary body depending on the stiffness of the bank note in the wave shape. When the bank note is new and stiff, the influence is strong, while when the bank note is old and deteriorated with a small stiffness, the influence is small. Such influence is detected from variation in rotary movement of the detection rotary body to which a predetermined rotational characteristic is given by a resistance imparting device.

Abstract: A measuring device measures the torsional rigidity of a motor vehicle weatherstrip of the type which tends to twist upon bending about its longitudinal axis as experienced during installation of the weatherstrip around a corner of a vehicle body opening. The measuring device includes a pair of a rotatably mounted arms carrying mounting shoes for gripping the weatherstrip at spaced apart points along the length of the weatherstrip. Pivot means mount the arms for movement to swing the mounting shoes in an arcuate path and thereby bend the weatherstrip about its longitudinal axis so that the weatherstrip tends to twist. An indicator clip is removably mounted on the weatherstrip intermediate the mounting shoes and twists with the twisting of the weatherstrip to indicate that the weatherstrip has experienced a predetermined degree of twisting during the arcuate bending of the weatherstrip.

Abstract: A device for detecting postal articles unsuited for mechanical handling is equipped with a bed of belts formed by a large number of side-by-side resilient belts (2) assembled with predetermined tension around two pulleys (3,4), which can turn freely around shafts fixedly mounted on a base plate. A conveyor belt passes over a guiding roller (6) opposite the bed of belts. The conveyor direction of motion is deflected around the roller and the bed of belts is taken along by the conveyor belt (1) by means of friction. An article on the conveyor approaching the guiding roller while moving between the conveyor and the bed of belts is subjected to a bending force when passing the guiding roller. The belts of the bed of belts here work as scanning elements. Deflection of one or more of them from the normal path, away from the guiding roller (6), can be detected by a combination (11) of an infrared radiator and a detector.

Abstract: A non-destructive method and apparatus is provided for testing a wood panel, such as a sheet of plywood, to establish values which may be used in calculating a measure of the modulus of elasticity (MOE) for the panel. The invention involves supporting the bottom surface of the panel horizontally with two spaced parallel rollers and contacting the top surface of the panel with a pivotally mounted loading bar which is adapted to apply linear loading to the panel substantially uniformly across its width, even though the panel may be warped or bent. The loading bar is biased by a double-acting cylinder so as to apply a first load and then, in quick succession, a second incremental load. The two loads are selected so as to fall on the substantially linear portion of the load deflection curve for the panel. The magnitudes of the two loads are measured with suitable means, such as a load cell. The extension or distance moved by the cylinder in applying the incremental load is known or measured.

Abstract: A limpness detector for examining documents at high speed. A pair of rollers having star-like cross-sectional configurations comprised of substantially V-shaped projections and interspaced V-shaped grooves are cooperatively arranged so that the projections of one of said rollers at least partially enter into the grooves of the other. The rollers are rotated in a synchronous manner. One swingably mounted roller is preferably yieldably urged toward the other. Documents to be examined are fed between the rollers and, depending upon their relative limpness or stiffness, serve to "lift" the swingable roller such that the amount of displacement between the rollers is a function of document limpness. Sensor means is utilized to detect the amount of displacement. Threshold detection circuitry is provided to facilitate calssification of the documents into limp, moderately stiff and stiff documents, for example. The apparatus may also be utilized to detect the presence of overlapping and/or multiply-fed documents.
