Abstract: Method of determining and evaluating the rapid power recovery capacity of a pressurised water nuclear reactor, consisting in calculating a recovery power by the application of the general formula:… Prip = Prel +  DELTA P,… in which Prip is the maximum recovery power available by actuation of the control rods, Prel is the relative power supplied by the core, determined by the in-line measurement of the neutron flux emitted by the core and  DELTA P is the additional power resulting from the potential reactivity of the assembly of the reactor control rods when this assembly moves from the observed insertion to minimal insertion,  DELTA P being calculated from the measured position of the power control clusters, involving the measured axial power distribution (C1 to C6) and the core exhaustion defined previously. …<IMAGE>…

Abstract: An optical device for detecting bar codes (markings or patterns which symbolize data such as the name and vendor of a product) are detected by an optical device which serves as a bar code scanner. A laser diode (44) and associated optics (51, 52) provides an invisible beam. A visible marker beam coincident with the laser beam is generated by a lamp (56) and associated optics (60, 62) and directed coaxial with the laser beam so as to enable the laser beam to be scanned across the bar code by moving a housing in which the laser (44) and the lamp (56) and their associated optics are disposed. Also contained in the housing is a photodetector (66) on which scattered light from the code is incident after passing through a collection lens (32) located at an outlet port for the beams. An aperture (92) is positioned between the collection lens (32) and the detector (66). The location and size of the aperture and the focal length of the lens are related such that the illumination by the reflected light of the detector is substantially constant and the output signal from the detector which represents the bar code is also constant amplitude over a wide depth of focus in front of the beam port. Unwanted reflections (gloss over the bar code) are rejected by selecting the polarization of the reflections opposite to the polarization of the laser beam, as by the use of a polarizing beam splitter. A spectral beam splitter is used near the detector to select the scattered laser light for the photodetector which generates electrical signals corresponding to the bar code.

Abstract: A photodetector system (10) for producing electrical signals responsive to the orientation of a light source, such as the sun, with respect thereto utilizes in certain embodiments a diffuser (11) to eliminate position-dependent sensitivities of the photo­cathode. The extent to which the diffuser (11) or the photocathode itself is exposed to the incident radiation can be controlled by a shroud (12) or by applying an absorptive coating (32) in a predetermined pattern on an absorber cap (40), or on the diffuser (11) directly. In a shrouded embodiment of the invention, the diffuser element (11) is arranged within a mountable body (13) with the shroud (12) extending thereover. The shroud (12), by its configuration and its height above the photodetector, defines the range of angles of elevation and azimuth at which the diffuser (11) can be illuminated. Such angles can also be controlled with printed or sprayed-on markings (30) on the diffuser or absorber cover (11) which form an opaque coating so as to prevent light transmission over predetermined regions. In addition to transmissive and nontransmissive regions, a fine dot pattern (32) may be applied to the diffuser or the absorber cover (11), which may be translucent or transparent, or to the diffuser (11) directly, so that only partial transmission of the light can be achieved therethrough. The absorber cover (11) may be provided with a light absorbing coloration or dye therethrough, and have a predetermined variation in thickness, so that the amount of light transmitted therethrough is responsive to the thickness at the point of incidence of the light. Thus, the light which is transmitted to the photodetector is modulated in response to the orientation of the light source with respect to the photodetector system.

Abstract: The invention relates to a process for heat recovery during sludge treatment, especially in the hygienisation of sewage sludge, in which raw sludge is maintained at a temperature of about 60 to about 62 DEG C in a reactor 1. It is proposed, for preheating of the raw sludge and for cooling of the hygienised sludge drawn off from the reactor 1, that a heat exchanger 5, which has at least two chambers 8, 9, is charged in alternate periods with raw sludge and hygienised sludge. In the first period, the raw sludge is introduced into the first chamber 8 of the heat exchanger 5 and subjected to heat exchange with the precooled hygienised sludge present in the second chamber 9. Subsequently the hygienised sludge is drawn off and discharged, for example, into the digestion tank. In the second period, the hygienised sludge, which is at about 60 to about 62 DEG C from the reactor 1 is introduced into the second chamber 9 and subjected to heat exchange with the raw sludge preheated in the first period. Subsequently the raw sludge is discharged into the reactor 1. The first period then starts again.

Abstract: A mill container (10) and a tumbling shaft (12) arranged in the latter together delimit a grinding chamber (20) which is divided into an inlet zone (22) and a separating zone (24). The inlet zone (22) is connected to a grinding stock inlet (14) and is traversed axially, at least over an essential part of its length, by the tumbling shaft (12). The separating zone (24) is connected in the axial direction to the inlet zone (22) and is arranged around a cage (25) which is incorporated in and entrained by the tumbling shaft (12) and open at one end. A separating device (16) arranged in the cage (25) retains the raw grinding stock (30) and any grinding aids (32) present in the grinding chamber (20) but allows the ground product (30) to flow out through a ground product outlet (18). The throughput is increased if the separating zone (24) extends over 40 % to 80 % of the total length of the grinding chamber (20) and the separating device (16) has an effective surface whose area is equal to at least 20 % of the inner surface of the mill container (10) which delimits the grinding chamber (20).

Abstract: The invention relates to electrically programmable memories, and in particular memories known by the acronyms "EPROM", "EEPROM", "FLASH-EEPROM". 
<??>To increase the information storage capacity of a memory, it is proposed to define at least three (instead of two) segments of current which issues from a cell to which reading voltages are applied; these segments correspond to n possible programming states for the cell. Comparators (COMP1, COMP2, COMP3) define an item of information stored for example in 2-bit form on outputs S1, S2. However, to ensure security when reading, despite the uncertainties of programming, the cell is tested with the aid of additional comparators (COMP1A, COMP2A, COMP3A) and if the measured cell current for a specified programming level, out of n, is too close to the current threshold defining the programming threshold at this level, an operation of supplementary programming of the cell is triggered.

Abstract: Agricultural distributor, for example fertilizer broadcaster, with a metering device which can be adjusted and set during travel by means of a remote-control device, the remote-control device having a fast actuation stage for adjusting the metering device from "no metering" to "metering" and a slow actuation stage for adjusting the metering device in order to change the discharge quantities. In order in a simple way to ensure as quickly as possible that the slide assumes exactly the desired opening position immediately at the start of or after any interruption of the spreading, the fast actuation stage is cut in during the setting of the discharge-quantity value near to the desired discharge-quantity value, and then the slow actuation stage is subsequently cut in until the desired value is reached.

Abstract: Centrifuged material layer measurements are made in an evacuated glass or clear plastic tube (2) which contains a float (6). When possibly contaminated materials, such as blood, are being tested the use of the evacuated tube allows the measurements to be made without the technician being exposed to the blood. The tubes are large enough to hold approximately one ml of blood, and are filled with an inert gas at low pressure. Dimensional tolerances relative to those of a capillary tube are relaxed for the tube and float due to the larger sample capacity. The cell bands (32) are stabilized by a layer of a flowable material which settles onto the plasma layer (34) during centrifugation and forms a pellicle thereon.
