Title: Method of operating a light water reactor
Inventor: MILLOT JEAN-PAUL
IPC: G21C7/26
Filed: 1983-10-27
Granted: 1987-07-02
Abstract: 1. A process for operating a light water moderated and cooled nuclear reactor having a core consisting of fuel assemblies immersed in the moderated and cooling light water and which are at least partially replaced at predetermined intervals, corresponding to operating cycles of the reactor, wherein : during a first phase of the cycle, neutron energy spectrum variation bars which are regularly distributed in the core are maintained within the core for decreasing the ratio between the volume of moderator and the volume of fissile material in the core and for shifting the neutron energy spectrum towards higher energies and, during a second phase of the cycle, the spectrum variation bars are withdrawn for operating with a lower energy spectrum, characterized in that the spectrum variation bars contain fertile material which absorbs the slow or low energy neutrons for locally obtaining an increased shift of the neutron energy spectrum towards higher energies resulting in an increased conversion of fertile fuel material into fissile fuel material.

Abstract: Methods and apparatuses are described for manufacturing, from a coextrusion, food pieces wherein an inner food is fully or partially enrobed by an outer food. In one embodiment the inner food is a dough that is enrobed by an outer dough by severing the outher dough with a blunt severing edge on a severing element which, as it enters the coextrusion, simultaneously draws the outer dough over the inner dough on both sides of the element to form the food piece. A coextrusion of an inner dough inside and outer dough is formed below a die with the extrusion of the inner dough periodically interrupted to form a region in the coextrusion where there is a greater amount of outer dough. A pair of severing elements are operatively located at a predetermined distance below the die where convergence of the severing elements cuts the extrusion in a region having a greater amount of outer dough while simultaneously drawing the outer dough over the inner dough above and below the severing elements. Several embodiments are described.

Date May 22, 1986.A method as well as an apparatus for processing asphalt mixtures is provided in which broken-up used asphalt is employed and new material is added, utilizing a plurality of burner-heated drum devices, with the used asphalt component and the new material for the asphalt mixture to be processed or produced being processed, i.e. heated in particular, in respectively differently configured drum devices. The used asphalt component is heated separately in a drum mixer operated with parallel flow and the new material component is heated in a drying drum operated with counterflow. After leaving their respective drum devices, the components are conducted into at least one further connected mixer and are further treated there with fresh bitumen and possibly with filler material being added in the mixer. Furthermore, the exhaust gases of the drum mixer are introduced directly into the drying drum and are further heated there, thus combusting the CHx and CO component contained therein. In this process, the exhaust gases of the drum mixer are introduced into the interior of the drying drum in the immediate vicinity of the burner flame through flow channels in the form of nozzles via a feed device formed at the frontal face of the drying drum in which the burner is disposed, with the direction of the nozzles being adjustable as a function of the size of the burner flame.

Title: Valve
Inventor: BERNARD JERALD DEAN
IPC: F15B11/08
Filed: 1986-04-24
Granted: 1989-09-14
Abstract: A spool valve has a seal-carrying spool movable in a valve bore terminated at one end by an end wall. A stem projects toward the end wall from an end of the spool. A hollow cylinder member is mounted coaxially on the stem via a radially inwardly extending flange which slidably receives the stem. A spring is coaxially mounted on the stem and is biased to urge the cylinder member away from the spool. A stop near the end of the stem retains the cylinder member on the stem and maintains a minimum preload in the spring. When the spool is in a position near the end wall, the end wall engages the cylinder member and moves it away from the stop, thereby compressing the spring so that the spring will be biased to move the spool away from the end wall.

Abstract: A process for preparing alkali metal salts of trifluoroacetic acid in the anhydrous and crystalline state. In a first stage, trifluoroacetic acid is neutralized with an alkaline agent in a medium consisting essentially of an alcohol containing 3 to 4 carbon atoms. In a second stage, the water formed by the neutralization reaction is removed by azeotropic distillation. In a third state, the remainder not removed by distillation in the second stage is treated by adding a hydrocarbon which does not solubilize an alkali metal trifluoroacetate and which forms an azeotrope with the alcohol to separate crystals of anhydrous alkali metal trifluoroacetate.

Abstract: A method and apparatus are described for the nondestructive readout of a latent electrostatic image formed on a sheet or layer of insulating material. A sheet or layer of semiconductor material is disposed in relatively close proximity to the insulating material forming a multi-layer material (41). The latent electrostatic image formed on the insulating material causes a surface depletion layer to be produced by induction at the surface of the semiconductor material. The location and distribution of the accumulated charges on the semiconductor material are read out by electronic circuits (59) as analog electrical signals corresponding to the ac surface photovoltage induced on the semiconductor material as the semiconductor material is scanned with a low intensity modulated light beam of appropriate wavelength generated by light source (53), the magnitude of the analog signals depending on the local charge density. The analog electrical signals so obtained are then digitized (61), processed (63) and stored and/or displayed (65).

Abstract: A hydraulically operated consumer appliance (3) is supplied with hydraulic fluid from a pump (2), and the flow to the appliance is controlled by the valve (1). The latter has a spring-loaded piston (8), with one side enclosing a chamber (5) in the valve body. The chamber is connected at one side to the pump through a non-return valve (26). The other side of the piston encloses a chamber (6) connected to the return flow tank (14). If the pump delivery flow rate exceeds the rate of consumption by the appliance, the pressure in the first chamber rises and moves the piston which, in turn, moves a sliding sleeve (12) so that a chamber (7), which is permanently connected to the pump, is then connected to the return flow tank.
