Abstract: Scintillation Camera Uniformity Correction Abstract A two-stage system (u) for enhancing imaging uniformity of a nuclear scintillation camera.  The system compensates for imprecision in the camera's indication of both radiation event regional image count density and event energy level.  A first stage (30, 32) locates and stores a representation of the respective peaks of the detected energy pulse height distribution for each of a plurality of regions in a camera's field of view.  This repre-sentation is used to successively realign for each count the pulse height energy window, to align the window over the respective energy peak for each count as a function of the count's location in the field.  A second flood correction stage (40, 42, 44) produces and stores a profile of regional variation in image count density indicated by the camera in response to a uniform radiation flood field.  The stored information is used for calculating regional count density correction factors for different regions of the camera field.  The correction factors are applied for controlling the ratio of radiation counts corresponding to each region which are actually imaged.

Abstract: Abstract of the Disclosure The present invention relates to processes for the preparation of novel tetrahydropyridine derivatives of the general formula (I)   in which R1 and R2 independently of one another are hydro-gen or alkyl containing 1 to 4 carbon atoms or together are alkylene  containing 3 to 5 carbon atoms, R3 is hydrogen, alkyl  containing 1 to 4 carbon atoms, alkenyl containing 3 or 4 carbon atoms, alkynyl containing 3 or 4 carbon atoms, cycloalkyl containing 3 to 6 carbon atoms or cycloalkyl-alkyl containing 4 to 7 carbon atoms and Y1 and Y2 are each hydrogen or together are an additional bond, and the ring A is not further substituted or is further substituted by alkyl containing 1 to 4 carbon atoms, alkoxy containing 1 to 4 carbon atoms, halogen with an atomic number of not more than 35, cyano, hydroxy or trifluoromethyl  and acid addition salts thereof. The compounds according to the invention have valuable pharmacological properties. In particular, they inhibit the absorption of serotonin by mesencephalic synaptosomes, the serotonin depletion induced in the brain of rats by H 75/12, and the absorp-tion of noradrenalin by mesencephalic synaptosomoes in rats and the noradrenalin depletion induced in the brain of rats by H 77/77. In the same dosage they also effect inhibition of monoamino-oxidase in the brain of rats and in the liver of rats. Furthermore, they intensify the "head twitch" in-duced by 5-hydroxy-tryptophan, and are distinguished by good tolerance. The compound of the general formula I and their pharmaceutically acceptable acid addition salts can therefore be used as psychopharmaceuticals and in parti-cular as antidepressants.

Abstract: "REEL-TYPE STUBBLE CONDITIONING DEVICE"          ABSTRACT OF THE DISCLOSURE         A frame assembly mounted in the windrow discharge area on a swather or windrower on which a plurality of ver-tical assemblies, are mounted thereto.  On these assemblies are mounted fraying and cutting blades.  These blades are operated at a required speed to fray and distort the tips of the stubble and/or cut and reduce the length of the straw of the standing stubble so as to ensure that the supportive strength of the straw is not exceeded by the weight of the swath or windrow placed upon it.  This will eliminate any dis-tortion or buckling of the remaining conditioned standing stubble straws.  A windrow delivery plate is mounted on the swather frame assembly within the windrow discharge area.          This plate assures delivery of the windrowed material onto the swath support fingers which effect a gradual release of the windrowed material onto the remaining standing frayed and conditioned stubble directly behind the frayer conditioners track of travel in the field.  The conditioned stubble height is controlled by a cantilever mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE     A corrugated metal building panel (e.g.,made of steel) is provided herein.  The panel has at least one (and preferably two) longitudinally extending major waves.  Each such major wave is provided with a plurality of spaced-apart, discontinuous, longitudinally extending wave-like stiffeners superposed thereon.  The wave-like stiffeners follow the general major corrugated pattern of the panel.  The spaces between the stiffeners include flattened portions of the general major corrugated pattern of the panel but in a preferred variant, also includes some wavelike corrugated portions interspersed between the flattened portions.  Furthermore, the stiffeners which are distributed along the major wave, always project from the exterior of the curvature of the major wave.  In this way, the local buckling factor is improved and the section modulus is increased, with the degree of improvement in local buckling factor and section modulus being optimized by the selection of a particular configuration from a series of alternative configurations.  Thus, the strength and rigidity of the corrugated panel is increased.

Abstract: ELECTRONIC LOADED/NONLOADED TELEPHONE      LOOP IDENTIFICATION CIRCUIT            Abstract of the Disclosure An electronic loop identification circuit identifies loaded and nonloaded customer telephone loops.  The loops can then be segregated to allow separate balance networks to be used for hybrid circuits which connect the customer loops to a digital switching office.  Separate balance networks for loaded and nonloaded loops improve singing margin on those loops.  An impedance measuring circuit measures the real part of the impedance of a connected loop which is compared to a reference signal.  If the real part of the loop impedance is greater than the reference signal, a loaded loop is identified; and, if the real part of the loop impedance is less than the reference signal, a nonloaded loop is identified.  The circuit includes a self-calibrating arrangement which connects a reference impedance to the impedance measuring circuit so that a capacitor held reference signal can be set before each loop identification operation.

Abstract: ABSTRACT OF THE DISCLOSURE An electronic test instrument for facilitating the analysis of a machine's response to cyclic perturbations in one of its control parameters and for adjusting the control parameter based upon the observed response so as to optimize the machine's performance. The instrument permits manual control over the rate and magnitude of the perturbation, the amount of bias, i. e., the deviation of the actual operating point from the optimum, and the upper and lower limits between which correction is permissible. The width of the engine's firing pulse can also be manually selected. To prevent undue hunting of the control parameter about an operating point, the instrument includes a buffering network that requires that the system call for a predetermined number of control parameter adjustments in a given direction before an actual correction will be effected. The number is selectable by manually settable switches.
