Title: Production of half tone facsimile separations with optional screen angles
IPC: H04N1/52
Filed: 1979-06-22
Abstract: A method for producing half-tone printing blocks having an optional screen angle and screen line spacing by line-wise scanning of an original and recording by means of a recording element displaced over a recording medium is described. The recording medium has co-ordinated with it an UV co-ordinate system directed in the line direction and and XY co-ordinate system turned through the screen angle, both co-ordinate systems being subdivided into areal elements from which the picture elements or half-tone dots to be produced are collated. Notwithstanding the screen angle beta , screen threshold values are associated with the areal elements of a limited scanning pattern range which corresponds to at least one mesh element of the screen which is to be recorded, as a function of their XY locus co-ordinates. During the recording operation, the UV locus co-ordinates of the areal elements momentarily traversed by the recording element are registered on the recording medium, are recalculated in the form of the corresponding XY locus co-ordinates of the limited screen scanning range under consideration of the screen angle, and the screen threshold values associated with the XY locus co-ordinates determined are "called up". A control signal which determines whether the areal element in question is or is not recorded on the recording medium as part of a screen element, is generated for the recording element by current comparison of the screen threshold values called up with the image signal obtained by scanning an original.

Patent ES-482532-A1 (ES)
Title: Apparatus and method for classifying empty beverage containers.
IPC: G07F7/06
Filed: 1979-07-17
Abstract: An apparatus for receiving and evaluating empty beverage containers. The empty containers may be received either individually or in cartons upon a moving conveyor. An alignment mechanism separates the containers and moves them to one side of the conveyor. A switch arrangement senses cartons, so that the system can process cartons of empty containers in a different manner than individual empty containers. The containers, whether individually or in cartons, pass through an illumination station wherein they interrupt illumination falling upon a row of photocells. Output signals from the photocells are transmitted to identification circuitry together with clock signals generated in synchronism with the movement of the conveyor. The identification circuitry generates registration signals, which are used to compute value of the containers being received. A paddle mechanism shifts the cartons to a separating station, which forwards properly filled cartons to a storage area. Improperly filled cartons are returned to a point near the receiving area.

Title: Method of determining a value proportional to the length of yarn axially unwound from a bobbin of spun or cross wound yarn and devices for performing the method.
IPC: G01B7/04
Filed: 1980-03-25
Abstract: There is measured the length of a thread withdrawn overhead from a spinning cop or from a yarn bobbin. In order to circumvent the fault sources caused by slip and/or thread elongation there is generated a signal which periodically varies in accordance with the movement of the thread release or detachment point at the spinning cop or at the yarn bobbin, as the case may be, and there are counted the number of cycles of the fundamental frequency of this signal. The thread length is obtained by multiplication of the counted number of cycles by the constant thread length of two successive winding layers for spinning cops or yarn bobbins of the same origin and the same thread. The periodic signal can be derived from the thread withdrawal force or from the number of revolutions of the detachment point. The method is particularly suitable when rewinding a number of spinning cops on to a cross-wound bobbin.

Title: Method of operating a nuclear reactor by displacing in the core of the reactor groups of control rods.
IPC: G21C7/36
Filed: 1981-11-02
Abstract: When the control parameter ( DELTA T) is within its deadband, a correction of the axial deviation of power (DA) is effected by movement of at least one group of control rods, when DA is outside a predetermined range or deadband straddling a reference value DA ref. The group which is moved is chosen as a function of the sign of DELTA T, of the position of DELTA T with respect to its deadband and of the position of the other groups. When DELTA T is outside its deadband, the differences between the amplitudes of insertion of the groups participating in the control of the reactor are made to vary by stopping or starting of groups selected as a function of the positions of the groups of rods (G1, G2, N1, N2) in the core of the reactor and of the position of DA either with respect to its deadband if DA is outside this deadband, or with respect to DA ref, if DA is within this deadband. The invention is in particular applicable to pressurized-water nuclear reactors.
