Abstract: ABSTRACT OF THE DISCLOSURE:            Reactor plant comprising a light-water-cooled reactor core with vertical fuel assemblies and with an inlet end and an outlet end for cooling water, a reactor vessel, a heat-exchanger, a water-filled pool, two hydraulic connections arranged between the reactor vessel and the primary side of the heat-exchanger, and a circulating pump for the primary circuit of the heat-exchanger.  The reactor core is contained in the reactor vessel and the reactor vessel arranged in the pool.  The coolant of the primary coolant circuit during normal operation is blocked from the pool water by means of a blocking device with a liftable blocking effect.  The pool water during normal operation is provided with an additive of dissolved neutron-absorbing material in such an amount that a complete replacement of the water of the reactor vessel with pool water means a reduction of the reactor power by at least 25 %.

Abstract: ABSTRACT OF THE DISCLOSURE:           High strength cement conglomerates are produced by adding to a mix of water, inorganic binder and aggregates a mixture containing  5 to 99.9% by weight of a polymer obtained by poly-condensation of an aldehyde with a sulphonic acid of the aromatic series, free or salified and soluble in water, and 0.1 to 95% by weight of a product of the hydrolysis of starch obtained from a raw vegetable material, the mixture being added into the mix in an amount of from 0.01 to 3% of the weight of the binder.    Water soluble inorganic electrolytes may advantageously be added to the mixture for significantly improving the characteristics of fluidity and cohesion of the fresh mix, and the characteristics of strength of the hardened mix.

Abstract: ABSTRACT OF THE DISCLOSURE         A pair of optical beams of radiant energy from separate paths in a spectrophotometer are coaxially merged into a single composite beam with an optical member which resembles a coarse echelette grating.  A reflective surface which includes the surfaces of sidewalls within a plurality of parallel grooves is disposed on the optical member.  The grooves are arranged in a lateral array and are generally V-shaped cross-sectionally.  The beams to be combined are directed upon the sidewalls and the composite beam is emitted therefrom in accordance with the law of reflection.  When the beams to be combined include non-collimated rays, shadowing is provided by the portion of the optical member between adjoining sidewalls of adjacent grooves to reduce flare.          Furthermore, image abberations as caused by off-axis operation due to use of a spherical mirror in the beam combining arrangement, are substantially corrected by the optical member.

Primary heat recovery is effected using liquid water or other cooling liquid and is performed in such a manner that the temperature of the liquid does not exceed its boiling point at atmospheric pressure. Secondary neat recovery is effected by indirect heat exchange between the exhaust gas of the furnace and a gaseous cooling medium and is performed in such a manner that the gaseous medium is heated to a temperature above the boiling point of the cooling liquid.  A part or the entirety of the cooling liquid is then heated by the gaseous medium.

Abstract: A B S T R A C T        For holding while machining the end enlargement or enlargements of an elongated otherwise thin deformable work-piece, such as a jet engine blade, the lower block of a two-part hinged fixture has mechanically-adjustable stops which predetermine the location of the front edge and front end of the thin portion of the workpiece and has three upwardly inclined support pins upon which the lower surface of the thin portion rests.  An upper block hinged to the lower block contains three downwardly-inclined correspondingly located clamping pins which bear upon the upper surface of the thin portion immediately above the lower support pins.  Each block contains horizontally-movable forward and rearward hold-fast pins for the workpiece end enlargements.  A multiplicity of pairs of aligned hydraulically-actuated upper and lower de-formation-preventing plungers in both the lower and upper blocks are then set in motion to press simultaneously  against the upper and lower surfaces of the thin portion of the workpiece while forward and rearward lower and upper plungers are urged outward against its opposite ends by spring pressure and locked hydraulic pressure fluid created by rotating a screw-threaded piston against hydraulic fluid already present in the upper and lower blocks of the fixture and communicating with the hy-draulicly-actuated deformation-preventing plungers through upper and lower networks of passageways.  The clamping plung-ers are hydraulically-actuated (Figures 1 to 5), or spring-actuated (Figures 6 and 7) , or screw-actuated (Figure 8).

Abstract: ANCHOR BASE FASTENER            Abstract of Disclosure.         An anchor base for integral plastic structures includes an articulated series of lever arms joined together in at least one joint by means of a living hinge in order to establish a preferred point of articulation.  The leverage is such that, as a first pair of the lever arms are squeezed together to insert them into a mounting hole in a chassis, a second pair of lever arms, for giving lateral support, are initially pulled down.  As the anchor base penetrates the mounting hole, the entire lever system pivots while lateral support levers are pushed up to spread the first pair of arms.  Shoulders on the first pair of arms are forced under the lower side of the chassis, in order to capture the anchor base and to resist its removal.  If the first pair of arms are thereafter squeezed together below the underside of the chassis, it is easy to remove the anchor base.

Abstract: ABSTRACT OF THE DISCLOSURE     A rectifier unit for 3-phase a.c. to d.c. conversion is of the type having a transformer with a star-connected and a delta-connected secondary the outputs of which are rectified and combined to give 12-pulse operation.  To reduce the danger of current imbalance between the two secondaries, a compensating transformer unit is interposed between the secondaries and the rectifiers which modifies the signals such that any difference in the current drawn from one secondary compared with the other tends to equalize the current drawn from the secondaries.  The compensating transformer unit can take the form of 3 individual transformer units but is preferably a single transformer with 3 limbs, each of which carries a main winding connected to one secondary and two opposed subsidiary windings which receive the phases from the other secondary which are closest to and on either side of the phase of the associated main winding.
