Title: Powder metallurgy workpieces prodn. system - in which carbon is added as necessary between annealing and compression stages before sintering
Inventor: DAIN RISHARD JAMES
IPC: B22F/
Filed: 1979-06-27
Granted: 1989-02-15
Abstract: The process produces metal items by heating a metal powder consisting mainly of tool, alloy or stainless steel or a high-tensile metal alloy. The powder is produced by pulverising and water-quenching of a melt to give irregularly-shaped particles, in a vacuum of 1.0 Torr at 900 degrees C to reduce the oxygen content, followed by controlled cooling to anneal the powder. The powder is compressed into blanks of >=60% relative density, and heated in a first stage in a vacuum below the setting temp. of the powder for at least half an hour to reduce the oxygen content to 0.7%. In a second stage their temp. is increased to a sintering temp., while a vacuum or partic. atmosphere is maintained round them. Sintering continues for 0.5-4 hrs. to increase the relative density to >=93%. The items are produced to standard dimensions, giving a charge weight of >=20 kg for the blanks heated in the first two stages. Between annealing and compression the powder is analysed for C and O content, C being added as necessary. Sintering temp. is selected to suit the C content, being maintained constant within +10 deg. C during sintering.

Title: Elimination of fixed and parasitic radar images - involves digital processing of echo phase comparison circuit outputs, and use of reference signal
IPC: G01S/
Filed: 1976-05-19
Granted: 1983-04-30
Abstract: Fixed object return radar echoes with a constant phase relationship to a reference signal while moving objects return variable phase signals. The phase comparison of these signals is converted into digital words for elimination of fixed and parasitic echoes while retaining moving target echoes. It-phase and quadrature radar signal resulting from reception of echoes are compared (37) with reference signal phasing to produce signals (39, 41) which are then converted (10) from analogue signals into digital words. These workds give echo distance and are processed (48, 50) by combining part of workd from one exploration with part of another exploration to produce correction signals representing average Doppler speed. Further combination and processing is effected to eliminate parasitic moving echoes.

Title: Process for the preparation of compounds for site-enhanced delivery of radionuclides and of chelating agents useful therefor
Inventor: BODOR NICHOLAS S
IPC: C07D285/00
Filed: 1985-07-19
Abstract: A dihydropyridine <SIGN> pyridinium salt type of redox, or chemical, delivery system for the site-specific and/or site-enhanced delivery of a radionuclide to the brain. A chelating agent capable of chelating with a radionuclide and having a reactive hydroxyl, carboxyl, amino, amide or imide group is coupled to a carrier moiety comprising a dihydropyridine <SIGN> pyridinium salt nucleus and then complexed with a radionuclide to provide a new radionuclide pharmaceutical that, in its lipoidal dihydropyridine form, penetrates the blood-brain barrier ("BBB") and allows increased levels of radionuclide concentration in the brain, particularly since oxidation of the dihydropyridine carrier moiety in vivo to the ionic pyridinium salt retards elimination from the brain while elimination from the general circulation is accelerated. This radionuclide delivery system is well suited for use in scintigraphy and similar radiographic techniques.

Abstract: A method is provided for growing highly oriented compound thin films on a substrate by subjecting the substrate to the vapor of a first single element which can react with the surface at a temperature sufficiently high for the reaction to occur which forms a single atomic layer of the first single element on the surface and then subjecting the thus formed surface with a first single element atomic layer thereon to the vapor of a second single element which can react with the first single element at a temperature sufficiently high for the reaction to occur so that a single atomic layer of the second single element is formed on the surface bound to the first single element. This procedure can then be repeated alternately subjecting the surface to the vapors of the first single element then to the second single element, etc. until the compound film reaches a desired thickness. There is further provided an apparatus for carrying out this method comprising a vacuum chamber with evacuating means, a support for supporting a substrate, sources for at least two vapors of two different single elements and operating means for providing on the substrate first a single atomic layer of one of the elements, and then a single atomic layer of the other of the elements.
