Abstract: DISPOSITIF ET PROCEDE DE TRANSPORT ET DE LARGAGE D'UNE PLURALITE DE CHARGES CONTENUES DANS UN CONTENEUR UNIQUE, ET CONTENEUR EQUIPE D'UN TEL DISPOSITIF. Invention de: Roger CREPIN Société dite: THOMSON-BRANDT L'invention concerne un dispositif et un procédé de transport et de largage d'une pluralité de charges contenues dans conteneur unique. Dans la virole du conteneur est agencée une pluralité de modules dont les corps contiennent une charge qui peut notamment être militaire ; ces modules sont extraits un à un, à la demande, par l'arrière de la virole. Cette extraction ne peut avoir lieu que si un organe mécanique de commande générale est passée d'une position dite de "sécurité" à une position dite "armée", mouvement qui ne peut avoir lieu que lorsque le moyen d'accrochage du conteneur est libéré du crochet qui la retenait à son véhicule porteur. L'invention s'applique notamment aux bombes modulaires à modules fragmentables destinés à la neutralisation au sol d'objectifs relativement étendus. FIGURE 6e

Abstract: ABSTRACT OF THE DISCLOSURE     The invention consists of a preamplifier for small signals generated in an inductive playback head by relative motion between the playback head and a magnetic recording medium having the signals recorded thereon.  It comprises amplifying means having an input and an output, means for extending the small signal from the playback head to the amplifying means input, and feedback means connected from the output to the input of the amplifying means.  This provides negative feedback of a portion of the signal applied to the input.  The feed-back means is operative to provide at the amplifying means output the integral of the signal within the playback head.

Abstract: ABSTRACT OF THE DISCLOSURE      Sulfur-containing compounds such as hydrogen sulfide and sulfur oxides arising from gasification or combustion of organic fuels such as coal may be removed from the hot gases by attrition resistant, highly reactive limestone-based sorbent agglomerates.  The agglomerates are formed by crushing and powdering naturally occurring limestone into grains with a binder that is stable at high temperature, for example a colloi-dal grade of attapulgite clay.  Volatile liquid is added to the mix of binder and powdered limestone to form a paste-like mix-ture, which is then agglomerated in compression-type agglomerat-ing equipment to form spheroidal agglomerates having good green strength.  In fluidized bed combustion applications, these ag-glomerates have attrition resistance equivalent to conventional natural limestone granules and far more reactive in terms of sulfur pickup.

Abstract: ABSTRACT     A new and improved computing apparatus for determining aircraft altitude has a pressure transducer to sense atmospheric pressure at which the aircraft is located, and from this and a preset local ground level atmospheric pressure reading, actually solve a non-linear altitude-pressure equation.  The computed altitude is used in con-junction with a time measurement to determine aircraft vertical rate.  The computed altitude also specifies an address in a memory circuit, with the data stored at such address being the grey code which is transmitted to others for air traffic control purposes.

Abstract: ABSTRACT        A method for developing a pattern of electrically conductive material on a ceramic substrate is disclosed. The method includes the steps of depositing on the ceramic substrate in a desired pattern a thin layer of a heat fusable material which contains a granular current conducting base metal.  An encasing layer is deposited over the pattern formed of the heat fusable material.  The encasing layer is formed from an oxygen barrier material containing an oxygen getting material.  This encasing layer is non-heat fusable and nonreactive with the heat fusable material.  All of this structure is heated in an oxygen containing ambient to a temperature sufficient to permit the heat fusable material to fuse to the ceramic substrate. The oxygen barrier material protects the granular, current conducting base metal of the fusable material from oxidation by physically blocking out oxygen and by chemically providing an oxygen getting material which will react with any oxygen which does manage to penetrate into the oxygen barrier material.  The ceramic substrate, fused heat fusable material, and remaining oxygen barrier material thereon are cooled back to room temperature and any remaining oxygen barrier material is removed from the ceramic substrate.

Abstract: ABSTRACT OF THE DISCLOSURE     A fuel control having an electrically operated metering valve and a manually operated metering valve through which fuel is independently scheduled to an engine.  During normal operation, the electrically operated metering valve controls the flow of fuel to the engine in response to an operator input signal.  Linkage connected to a power lever supplies the manually operated metering valve with an input corresponding to the fuel flow requirement requested by the operator of the electrically operated metering valve.  The manually operated metering valve is connected to the source of fuel through an electrically operated transfer valve.  Should an electrical failure occur, the electrically operated transfer valve is deactivated and if the fuel flow requirement is below a fixed level, fuel flows from the source through the manually operated metering valve without moving the power lever to maintain a substantially constant engine speed.
