Patent ES-307183-A1 (ES)
Title: Containment system for pressurized nuclear reactor installation
IPC: G21C1/20
Filed: 1964-12-16
Abstract: In a superheated steam generating, heavy water moderated, nuclear reactor power plant, provision is made to prevent the escape of radio-active contaminated coolant into the atmosphere following a fault in the coolant circuit. The fault is considered to have two separate phases, in the first, a large column of uncontaminated coolant high pressure is permitted to escape, in the second phase, the reactor fuel element sheaths fail, due to loss of coolant, and fission products are released with a small volume of low pressure coolant which is prevented from escaping. Steam may escape from the coolant circuit through condensing water pools for a period of 20 seconds, following this, pressure-sensitive elements close vents to the atmosphere and steam and fission products, subsequently discharged from the reactor are retained in the turbine hold, designed to withstand low pressures. A relief valve is mounted at the end of the turbine hold remote from the reactor from which steam and air may escape initially. The resulting reduction in pressure is such that the valve closes before contaminated vapour reaches it. If a failure occurs within the core it is considered that fission products will be released immediately as low pressure. To prevent escape in this instance, burstable panels are mounted over the vents which retain the contaminated vapours. High pressure faults of the first type would remove the panels to permit the pressure controlled vents to operate.

The variable length of the melt duct may be achieved by the use of more than one helical turn 11 or by replacing the duct by cylindrical tubes, one sliding within the other in a fluid-tight manner. The heating container may be subdivided into two heating sections by a partition above the nozzle assembly, and a separate supply of heating medium may circulate in each section.

Title: Laminated Glass Assembly
IPC: B32B17/10
Filed: 1967-09-30
Abstract: In laminated safety glass having a plastics layer interposed between two sheets of glass, at least one of the latter is of float glass and is arranged with its face that has been in contact with the bath during its formation exposed and with its other face, which may have surface irregularities, adjacent to the plastics layer. As a result of the lamination process, the plastics which has a refractive index similar to that of the glass, e.g. polyvinyl butyral, fills the surface irregularities. The other sheet of glass may also be of float glass or it may be of plate glass. The sheets of glass may be bent prior to being laminated so as to form a windscreen when laminated by heat and pressure. The bloom on the face of the float glass to be exposed in the laminate may be reduced by polishing or by reducing the degree of oxidation of the tin in the float chamber during the manufacture of the float glass.

Patent ES-392607-A1 (ES)
Title: Color bar printer
IPC: G06K1/12
Filed: 1971-06-25
Abstract: A printer, which includes a pair of green printing elements and a pair of black printing elements, causes a sequence of green, black, and white colored bars to exist on a tag, where the green and black bars are printed and the white bars are the tag color resulting from a lack of printing. The tag is moved through the printer in discrete steps of two bar widths at a time, so that two new areas of the tag are beneath each pair of printing elements after each discrete movement. Signals are then applied to those printing elements which are then to print bars. A ribbon, which is associated with each pair of printing elements, is moved one bar width each time a print signal is applied to the pair of printing elements. This movement occurs after the leading one of the printing elements prints and before the trailing one of the printing elements prints. Logic circuitry is also included for converting a binary code into signals representing the colored bar code and for providing necessary signals to the printing elements and the ribbons. The code-converting circuitry uses a module three up-down counter, and the then existing count in the counter represents the then required color bar.

Title: Electrically controlled target throwing device
IPC: F41J9/24
Filed: 1974-07-17
Abstract: Apparatus for throwing "clay pigeons" for target shooting wherein a spring driven throwing arm is moved to the "cocked" position through the action of a drive including an electric motor.
