Abstract: The subject-matter of the invention is an intrinsic-safety nuclear reactor of the pressurized water type, having: - a reactor vessel (2) equipped with a core (4), a lower header (5) and an upper header (6), at least one heat exchanger (3) with a secondary fluid, means of hydraulic connection (9, 10) between said headers and said heat exchanger and at least one circulation pump (11), - a pressurized container (1) surrounding the reactor vessel (2) and which defines a tank (5) full of a cold, neutron-absorbing liquid; - pipes (20) allowing communication between the lower area of said tank and the lower header of the vessel, as well as pipes (21,22) allowing communication between the upper area of said vessel and the upper header, in which the pressure drop in the primary fluid across the core is substantially equal to the difference in head between the cold column of said tank and the hot column of the vessel. According to the invention, said pressurized container (1) is immersed in a pool (18) containing a neutron- absorbing liquid at atmospheric pressure. Furthermore, the wall of the vessel (2) is insulated, while the wall of the container (1) has no insulation, so as to achieve the greatest possible heat exchange between said wall and the water of the surrounding pool (18).

Abstract: Live vaccines are provided and methods for preparing the live vaccines for protection of a host from a pathogenic microorganism. The vaccines are prepared by introducing at least one modification in a gene involved in at least one, normally at least two, biosynthetic pathways involving the production of products which are unlikely to be found in the disease susceptible host. The modification results in a gene change which cannot be repaired by a single step, e.g. polynucleotide deletions and inversions. Where the aro gene suffers such a change, the resultant auxotrophic mutants require aromatic amino acids, p-aminobenzoic acid and 2,3-dihydroxybenzoic acid or a highly concentrated source of absorbable iron. The auxotrophic mutations have substantially reduced or nonexistent virulence while retaining the desired immunogenicity to initiate the immunogenic response. Various techniques can be employed for providing the desired change.

Abstract: A coupling for either rigidly or flexibly connecting the adjacent ends of a pair of aligned pipes (13, 14) is formed of a circular casing (10) made of a pair of aligned, semi-circular segments (11, 12) which surround a resilient pipe gasket (23). The opposite ends of the segments have radially outwardly extending lugs (25) which form pairs of overlapping fastening lugs. The lugs (25) of at least one pair each have transversely aligned bolt holes (28) and opposed sockets that are generally concentric with the bolt holes (28) and open towards each other. A bolt (30) extending through the sockets and bolt holes fasten the lugs (25) together and cause the segments (11, 12) to clamp radially inwardly towards the pipes (13, 14) for coupling the pipes together with some permissible flexibility of relative movement. A plug (40) having opposite end portions and a central bolt hole (43) is removably fitted within the opposed lug sockets, with the bolt extending through its central bolt hole. The plug end portions are offset from each other in an axial direction, relative to the axis of the coupling, so that tightening a nut on the bolt wedges the overlapped pair of lugs apart in an axial direction for causing the segments to clamp axially and radially against the pipes and rigidly hold them against relative movement.

Abstract: A field-based movement sensor adapted for measuring strain along a certain axis in an object on which the sensor is attached. The sensor includes a substrate having a working surface and formed with a pair of fingers projecting from a first direction, and a third finger projecting from a direction opposite the first direction, to a position between the pair of fingers. The pair of fingers and third finger extend generally perpendicular to the axis along which strain is to be measured, with the pair of fingers being moveable with respect to the third finger along the axis when the strain occurs. An electrically charged element for producing an electric field is disposed on the working surface of the third finger, and a pair of field-effect transistors (FETS) are each disposed on a working surface of a different one of the pair of fingers. As the object is subjected to strain causing the pair of fingers to move relative to the third finger, the variations in the strength of the electric field from the charged elements to the FETS is determined and this provides a measure of the variation in distance between the third finger and the pair of fingers and this, in turn, provides a measure of the strain in the object to which the substrate is attached.

Abstract: A device and method for permitting the separation of plasma or serum from whole blood. The device comprises a matrix of hydrophilic sintered porous material to which at least one red blood cell agglutinating agent has been applied. According to a first method of using the device, a sample of whole blood is applied to a first end of the matrix and the red blood cells within the sample come in contact with the agglutinating agents present in the matrix. The blood cells agglutinate, and are entrapped in the interstices of the matrix, while substantially blood-cell-free serum or plasma accumulates near the outlet of the device. A filter means in liquid receiving relationship with the matrix functions to wick the serum or plasma from the matrix. According to an alternative aspect of the invention, a filter means in liquid receiving relationship with the outlet of the matrix functions to retain any blood cells which pass through the matrix as the filter means wicks the plasma or serum from the matrix. Additional agglutinating agents may be incorporated within the filter means to facilitate retention of blood cells which pass through the matrix. Another aspect of the present invention involves a device for the measurement of a serum or plasma sample, utilizing a matrix of sintered porous material, such as sintered glass, sintered steel, sintered ceramics, sintered plastics, and eguivalents thereof. The matrix is characterized by a reproducible fluid uptake capacity proportional to the fixed dimensions of said matrix, a minimal reactivity with plasma or serum components, and a hydrophilic internal surface which enables the matrix to collect and retain a predetermined volume of sample for analysis. A further aspect of the present invention provides a porous reagent delivery system comprising a matrix of sintered porous material containing at least one reagent in a freeze-dried state, and method for making same. The system allows the delivery of a unitized form of a freeze-dried reagent which is recoverable upon contact with a liquid.

Abstract: Chromium carbide powder and/or powder of an easily sulfidable metal are added to powdered crude metallic chromium to form a mixture thereof, which is then heated in vacuum to remove S, N and O by degassing so that consequently the crude metallic chromium is free from impurities to a possible maximum extent. Alternatively, powdered crude metallic chromium is heated in an atmosphere of inert gas to temperature between 800 and 1,400 DEG C and then an easily sulfidable metal is added thereto to form a mixture thereof. Subsequently, the mixture is, directly or after adding carbon or chromium carbide, heated again in vacuum or in an atmosphere of inert gas to eliminate S, N and O by degassing so that the crude metallic chromium is free from impurities to a possible maximum extent. Still alternatively, powdered crude metallic chromium is washed with inorganic acid such as hydrochloric acid, sulfuric acid or nitric acid or organic acid such as acetic acid to remove metal impurities such as Fe. The washed crude metallic chromium is then mixed with carbon or chromium carbide and the mixture is heated in vacuum or in an atmosphere of inert gas to eliminate S, N and O by degassing and consequently produce high-purity metallic chromium.

Abstract: Soil microorganisms are obtained that produce a hemicellulase which is particularly useful in increasing the available energy content of hemicellulosic foodstuffs. These microorganisms can be cultured per se or can be used as sources of genetic information with which to engineer other microorganisms to produce the enzyme. Thus, commercially useful quantities of native or recombinant hemicellulase can be produced with cultures consisting essentially of microorganisms that produce the enzyme. The hemicellulase can then be employed in a feed composition containing complex carbohydrates which the enzyme degrades, enhancing the nutritional value of the composition.
