Abstract: ABSTRACT:    A process for the fluid-bed gasification of ash-containing carbonaceous solids with steam to produce synthesis gas wherein heat is supplied to the gasification zone by passing therethrough a stream of agglomerated ash particles, formed by heating ash particles derived from the carbonaceous solids in a combustion zone at a temperature sufficient to render the ash particles tacky and to cause them to undergo agglomeration.  The agglomerated ash particles are formed in a separate fluid-bed agglomerating combustion zone and the resulting agglomerated ash particles introduced into the main combustion zone where they are maintained below agglomerating temperatures but at sufficient temperatures to sustain the gasification zone.

Abstract: ABSTRACT OF THE DISCLOSURE         Grain is cleaned in a dry state and then admitted into a washing chamber for the removal of residual contamin-ants.  The grain is then introduced into a centrifugal dryer where excess water is removed.  Sufficient water remains in the grain so that it has a moisture content between 18 and 24% by weight.  This moisture content is such that the outer layers of individual grains become swollen thereby activating enzymes in the outer layers which are capable of synthesizing vitamins while, however, initiation of germination of the grain is avoid-ed.  The grain is now conveyed into a heating chamber where it is heated to temperature between 25 and 35°C.  Thereafter, the grain is admitted into an insulated silo composed of corrosion-resistant material where it remains for a period of 5 to 30 hours while the moisture content and temperature are maintained within the respective ranges indicated above.  In the silo, vitamins are synthesized by the activated enzymes. The grain travels through the silo and, in order to ensure that this occurs in a uniform manner, a vibrating valve is provided in the region of the outlet end of the silo.  Subsequent to issuing from the silo, the grain may optionally be conveyed through a steam chamber for the purpose of destorying microorganisms which may be present in the grain.  Also optionally, the grain may be held at tempera-tures between 40 and 50°C after issuing from the silo in order to permit decomposition of Phytin to occur. Thereafter, the grain is dried to a moisture content between 14 and 16% by weight so as to bring the grain into a grindable state.  The grain may then be brushed and exposed to suction so as to remove and separate  loosened skin and other contaminants from the grain.         The thus-treated grain is particularly well-suited for proces-sing into foods.  On the one hand, the baking characteristics of the grain are good since the quality and quantity of the gluten present in the grain are retained, which is not the case when germination of the grain occurs.  On the other hand, the nutritional value of the grain is high due to the vitamins synthesized by the activated enzymes.

Abstract: WATERPROOF ELECTRICAL CONNECTOR                 ABSTRACT OF THE DISCLOSURE         A Separable waterproof electrical connector for a plurality of pairs of axially interconnectable cylindrical electrical terminals coupled to the ends of insulated wires, each terminal having an annular external recess in its cylindrical peripheral surface.         The connector comprises a pair of elongated, rigid, non-conductive elastomeric, tubular members having generally complementary end portions fitted one into the other.  A soft elastomeric sealing sleeve is concentrically interposed between the interengaged end portions to prevent the passage of moisture therebetween.  Releasable clamping means on the exterior of the tubular member end portion hold the latter in engagement.  Each elastomeric tubular member has an interior partition wall extending laterally of its longitudinal axis in juxtaposition to the interengaged end portions.  Each partition wall has a plurality of axially extending apertures therethrough that are equally spaced around the longitudinal axis of the tubular members.  The electrical terminals are seated in the apertures.         A portion of the wall of each aperture comprises an axially extending cantilevered locking member hinged at one end to the partition wall and having a detent spaced from its hinged end.  The detent is adapted to engage the external recess on the terminal seated in a respective aper-ture to prevent axial displacement of the latter.  Each partition wall has an axially extending cavity communicating with the locking members.  A displaceable plug means is seated in the partition cavity in abutting relation to the locking member to hold the detents on the latter in the respective terminal recesses.        A grommet is seated in the tubular member outwardly of the partition wall through which the insulated wires extend.  The grommets are in sealing engagement with the interior walls of the tubular members and the insulated wires in watertight relation.

Abstract: PROCESS FOR THE PURIFICATION OF       ELECTROLYSIS BRINE             Abstract Brine is purified prior to electrolysis by dividing it into two streams, removing sulfate from one of the streams by precipitation with calcium chloride to form calcium sulfate, removing the precipitate and re-combining the streams.  Alkali hydroxide plus sodium carbonate are added to the re-combined streams to precipitate calcium carbonate which is removed.  Any magnesium comes down as the hydroxide.  The brine is then pure enough for electrolysis.  The calcium sulfate first precipitate is reacted with sodium hydroxide and carbon dioxide to form calcium carbonate which is then reacted with hydrochloric acid to form calcium chloride which is recycled to the process for precipitating calcium sulfate.

Abstract: Abstract The invention is concerned with an installation or plant for storing oil and similar petrol products in several underground storing rooms each communicating with a common oil-filled pump chamber housing submersed pumps for pumping out oil from any of the rooms. Selective pumping requires valves for selective connec-tion of room outlet pipes with a pump inlet pipe. Submersed location of those valves in the pump chamber, according to the prior art, involves several disadvantages such as the need of draining the complete system for repair and maintenance work on the valves, and, difficulty to remote-control the valves. These advantages are, according to the invention, eliminated by the use of a dry valve chamber sealed-off from an oil-containing pump chamber housing submersed pumps.

Abstract: A B S T R A C T            A data security system employing an automatic time-stamping mechanism for stamping a time accrued in a data storage area or register associated with each envelope or block of a memory or for each data channel of an auxiliary storage device, such that each access or data updates the appropriate time stamp in the memory of storage device.  A first instruction provides the fetch of the time stamp with regard to the main memory, and a second instruction provides the fetch with regard to information contained in the data channel corresponding to the auxiliary storage device.  For every envelope of a memory, there is a time stamp tag register associated with it. Similarly, there is a time stamp register associated with every data channel.        Whenever an envelope of memory is accessed, the time stamp in the form of a unique binary number from a clock, indicating the time of day, is inserted into the tag register associated with that envelope.  Examination of the contents of each tag register enables determination of whether there has been access to an envelope up to the present time.  A full memory address register is used to access data in the memory while only special high order bits of the memory address register are used to access the time stamp associated with the envelope.    The system provides a mechanism which automatically marks blocks of data as they are accessed and cannot be bypassed by altering the program.
