Abstract: Abstract of the Invention A diaphragm operated, air fuel control system for controlling the rate of fuel flow to an internal combustion engine in response to intake manifold pressure is disclosed wherein the transient response of the diaphragm operator is attenuated by a fuel filed control chamber.  An attenuator assembly connected with the control chamber causes fuel to be supplied to the chamber at a rate which is greater than the rate at which fuel may be discharged from the control chamber. In one embodiment the chamber is formed on the side of the diaphragm operator which is opposite to the side to which intake manifold pressure is supplied.  In  another embodiment the control chamber is formed to receive one end of a plunger valve connected with the diaphragm operator.

Abstract: ABSTRACT          Disclosed is apparatus and method for electrochemi-cally finishing the edges of airfoils and other thin edged objects.  When the edge on an airfoil varies in thickness along its length, a tapered electrode is provided which has both a decreased diameter and increased spacing distance, providing a means for obtaining an edge with a radius proportioned to the thickness.  Generally, in the system having an electrode with a unit surface area A, and with an electrode-workpiece surface spacing distance S, both A and S vary so that the ratio A/S is lowered for electrode portion  proximate to edge portions having lowered thickness.

Abstract: ABSTRACT               "METHOD OF FORMING SEALING GASKETS       IN CONTAINER CLOSURES"          The invention relates to forming sealing gaskets in container closures of a high-melting olefin polymer, especially polypropylene.        Sealing gaskets for metal closures, especially bottle caps, have conveniently been formed in the closure by depositing therein a plastisol of a vinyl chloride resin, shaping it and fluxing it in an air oven at 190 to 250°C.        The above process cannot be applied to polypropylene closures, melting at about 165°C, using the conventional plastisols.  Attempts to use plastisols which flux at a lower temperature failed because of other problems.  Other processes proposed involved supplying energy to the plastisol inside the closure without heating the closure itself directly.          Thus microwave heating was tried but led to intolerable overheating of the interior of the plastisol in order to flux its surface adequately.        The invention uses a combination of microwave heating and controlled heating by conventional means.     Even though the conventional heating is not by itself sufficient to flux the plastisol, the combination has surprisingly been found to cause the surfaces of the gasket to be adequately fluxed without the overheating effect.  The controlled conventional heating produces a closure temperature of from 5 to 35°C, preferably 5 to 15°C below its melting point at the time of the microwave heating.        The invention is useful in the gasketting of closures of high-melting olefin polymers principally for bottle caps, jar lids etc.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for computerized axial tomography (CAT) image reconstruction applicable to X-ray scanning of the human body.  Successive series of calculations determine the values of a characteristic in defined segmented areas of an examination plane.  A reduction in the time and equipment require-ments for reconstruction calculations may thereby be effected.  Images representa-tive of the difference between the value of the characteristic at a reconstruction point and the average value of the characteristic in adjacent regions (.DELTA.µ) may be calculated and displayed from measurements taken within a localized contiguous region of the examination plane.  Radiation dose to patients and computation time in X-ray computerized axial tomography scanning systems is thus reduced. Differential displays of the type described may be adjusted to image boundaries, in which case they do not suffer from gray scale resolution problems which are typical of prior art displays.

Abstract: MULTIPLE TONE PILOT SIGNAL SYSTEM            ABSTRACT OF THE DISCLOSURE   multiple low frequency tones are employed for stereo indication in an AM stereo radio system. The tones are modulated on a carrier wave which is also multiplex modulated by stereo related audio signals.  Detection of the presence of one of the tones in a received signal provides an indication of the possibility of stereo related modulation components in the received signal.  Detection of the presence of both tones in the received signal provides confirmation that stereo related modulation components are in the received signal.  In a preferred embodiment, 15 Hz and 30 Hz phase-related tones are used.  A stereo receiver incorporates 15 Hz and 30 Hz phase detectors which form interrelated phase-locked loops with a 30 Hz reference oscillator.  The presence of both tones in the proper phase relationship indicates reception from an AM radio station which is broadcasting in stereo.
