Abstract: A radiographic method and apparatus for nondestructively monitoring a specimen for density variations are disclosed.A positron-annihilation-radiation-emitting point source is situated approximately midway along the axis separating two detectors sensitive to positron-annihilation (0.511-MeV photon) radiation. The outputs of the two detectors are fed to an electronic circuit that reckons only time-coincident events that are sensed simultaneously in the two detectors. The specimen to be measured is positioned between the source and one of the detectors such that the cone of detected, i.e., coincident, photons intercepts the region of interest. The number of coincidences that are counted in a preset time interval are recorded, or, alternatively, the coincidence count rate is monitored directly with a ratemeter.

Abstract: A process for the production of a "fuel grade" mixture of methanol and higher alcohols from CO and H.sub.2.To reduce the amount of water contained in the mixture coming from the synthesis reactor of the alcohol synthesis the reaction product is cooled and fed to a secondary reactor wherein the reaction of conversion:CO+H.sub.2 O.revreaction.CO.sub.2 +H.sub.2is conducted in conditions near to equilibrium.The further reaction product is cooled down further so as to obtain a liquid phase constituted by the alcohols, and in which there are still dissolved some gases, and a gaseous phase containing the carbon dioxide produced in the secondary reactor together with the non-reacted gases. The gaseous phase is sent to a section of absorption of the CO.sub.2 wherein the absorbing liquid is constituted by the very alcoholic mixture produced; after removal of the CO.sub.2 the gas is partly recycled and partly let off in order to avoid the accumulation of inert gases contained in the feeding mixture.

Abstract: An apparatus and method for use in an n-element electronically scannable array antenna provides a notched auxillary radiation pattern for use in reducing interference energy received in the sidelobes of the antenna's main radiation pattern. The apparatus includes circuitry for feeding the antenna elements in series from one end of the array to the opposed end thereof. Each antenna element is fed through a directional coupler which is responsive to its associated antenna element along with the downstream antenna elements in the array. The directional couplers provide a first output signal for forming a primary radiation pattern. At least one directional coupler also provides a second output signal on receive for forming an auxiliary radiation pattern having a notch in the direction of the primary radiation pattern main beam and electronically steerable therewith, and a relatively uniform response in all other directions.
