Abstract: 9- l 1-1977 ABSTRACT:     In tomosynthesis, as is known, a series of individual images taken-in different orientations, are superimposed. By shifting the individual images relative to each other the position of the layer which is sharply re-produced can be changed. However, there may still be unsharpness in said layer, in the case of image distortion during recording of the individual images, for example owing to the curvature of the input screen. This image distortion can hardly be compensated for, because it greatly depends on the projection angle. The invention provides a simple method of compensating for such image distortion. The image intensifier is then arranged and steered so that its optical axis is always parallel to the central ray. The distortion caused by the image intensifier curvature is then independent of the projection angle and can be eliminated in a com-paratively simple manner. Steering the image intensifier in this way gives rise to additional distortion, because the planes, of which subsequently laminar radiograms are made by superposition, and the optical axis of the image inten-sifier are no longer perpendicular to each other. However, this is a simple geometric distortion which can be eliminated in a simple manner.

Abstract: DEMODULATOR FOR FREQUENCY MODULATED SIGNALS                       ABSTRACT         This new demodulator for frequency modulated signals separates the signals into two distinct paths and delays the signals in one of the paths, with reference to those in the other of said paths, by an integral odd multiple of a quarter of one wavelength of the center wavelength of the signals.  A phase detector compares the outputs of said two paths and pro-duces an output varying in amplitude according to the phase difference between the signals at the outputs of said two paths. The above improvement has peculiar advantages in FM receivers for the relatively weak, wide band (excess of 2MHz), frequency modulated, television signals received from satellites.

Abstract: ABSTRACT OF THE DISCLOSURE         A device for use in the art or craft of molding hollow artistic objects from thermoplastic molding material, such as wax.  The molding device includes a frame with a vertical stationary, circular gear rack secured thereto.  A crank driven shaft is journaled through the frame in a position concentric with the rack.  A yoke-like mold carrier is secured to the end of the shaft for rotation therewith.  A mold holder is, in turn, mounted on the mold carrier for rotation about an axis generally perpendicular to the crank shaft axis between the yoke arms of the mold carrier.  The mold holder has a shaft projecting through one of the yoke arms of the mold carrier and is secured to and driven with a disc gear, which is enmeshed with the gear rack.  As the crank is turned to rotate the mold carrier, the disc gear rides on the gear rack and rotates the mold holder.  In operation, a mold in the form of a pair of mating mold halves providing a mold cavity is supplied with molten thermoplastic material, assembled, and mounted on the mold holder.  Turning of the crank causes the mold to be rotated on the two generally perpendicular axes and generally evenly distributes the thermoplastic material on the interior of the mold cavity surface as it cools and sets.

Abstract: ABSTRACT            A screwless electrical terminal unit comprises a pair of parallel channels for receiving respective conductors, with the open sides of the channels facing one another.    Between the channels is mounted a W-shaped leaf spring with its central bend mounted on a retaining member, each outer bend adjoining an abutment between the outer bends to limit movement of the latter, and the free limbs extending obliquely towards respective channels for clamping conductors therein.    Such an arrangement ensures that manipulation of one limb of the spring has no effect on the clamping of a conductor by the other limb.    A rocker member may be provided for selectively moving the free limbs from their conductor- clamping positions.

Abstract: LEAK TESTING METHOD AND APPARATUS FOR TUBULAR MEMBERS AND PACKER MEANS THEREFOR            Abstract of the Disclosure A body having a longitudinal opening through which a tubular member may extend for testing, such as two tubular members connected together by threaded connections or a coupling.  Positioned along the longitudinal opening in the body are longitudinally spaced annular seal means.  The body includes passage means for conducting fluid pressure against the outer circumferential surface of each of the annular seal means.  Back-up means are mounted in association with each annular seal means for inward and outward radial movement with such seal means, each of the back-up means comprising anti-extrusion means to prevent significant extrusion of the seal means responsive to pressure imposed thereon.  Means on each of the back-up means and on the seal means coact to urge the back-up means into tighter frictional engagement with the tubular members upon the application of a continuing radial force to the seal means by the pressurized actuating fluid after the seal means are moved into sealing engagement with the tubular member.  The application of the pressurized actuating fluid against the outer circumferential surface of the annular seal means forces the seal means and the back-up means carried thereby into engagement with the tubular member whereby the spaced annular seal means and the body form a closed chamber which seals the exterior of the tubular member.  The body includes a further passageway for supplying a pres-surized test fluid into the closed chamber for externally testing the tubular member.
