Patent ES-352694-A1 (ES)
Title: Improvements relating to thermal insulation
IPC: F16L59/04
Filed: 1968-04-11
Abstract: The reactor concrete pressure vessel 1 has a metal lining 2 which is covered by a layer of non- metallic fibrous insulating material, 4, secured by the studs 3 and metal sheets 6. The material 4 is compressed by the metal coverplates, 7, engaged by the nuts 8 and washers 9. The latter make line contact with 7 to reduce heat losses, and thermal convection within the fibrous layers is prevented by the metal strip seals 12. Gaps between adjacent coverplates 7 serve as vents to permit rapid gas pressure changes without damage. Metal gauze filters are fitted at the gaps. An alternative form of seal 12 is formed by corrugations in the sheets 6, of sufficient depth to engage the adjacent sheets. The seals may extend through one or more layers of the insulating material. Distance pieces 5 may be provided between successive layers of insulating material or shoulders may be mounted on the studs 3.

Patent ES-447943-A1 (ES)
Title: Hydraulic ram valve unit
IPC: F04F7/02
Filed: 1976-05-14
Abstract: A ram valve is connected in the supply line through which water flows at a high mass flow rate. A branch line branches off upstream of the valve and includes a check valve and a pressure vessel upstream of the check valve. The ram valve is constructed to have an elongated valve housing and a movable valve body therein, slidable axially in the direction of flow, and shaped to provide for smooth fluid flow therethrough when open and forming a smoothly continuous decreasing flow cross-sectional area. The valve body is held open by an adjustable force, such as a spring or a magnet. When the force is exceeded, the valve body closes suddenly, causing a pressure pulse to be transmitted through the then open check valve into the branch pressure vessel to build up pressure therein. A closed supply pressure vessel having an air cushion is included in the inlet supply line to the valve. The pressure vessels, the supply line, the ram valve and the check valve are a unitary assembly capable of installation and transportation as a unit, the inlet supply line preferably being formed as a spiral coil surrounding the branch pressure vessel and terminating in a tangential outflow to decrease flow turbulence to the valve.

Title: Means for reducing cavitation-induced erosion of centrifugal pumps
IPC: F04D29/66
Filed: 1976-12-23
Abstract: Erosion of parts owing to cavitation in the part-load region of operation of a centrifugal pump is reduced or eliminated by equipping the pump with an annular diffuser which is installed upstream of the annular intake of the impeller. The impeller portion immediately downstream of the inlet edge, where the vanes begin, is bounded by a surface which diverges at an angle of 8 to 20 degrees, as considered in the direction of fluid flow in the impeller. The diffuser has a smaller first cross section which is remote from and a larger second cross section which is nearer to the impeller. The area of the smaller cross section is between one-half and nine-tenths of the area of the larger cross section. If the diffuser has a conical internal surface, the angle of divergence of such conical surface (as considered in the direction of fluid flow toward the impeller) is between 5 and 15 degrees. If the diffuser is internally stepped, the ratio of its length to the diameter of the larger cross section is between 0.2 to one and one to one.

Title: Single stroke dispensing apparatus
IPC: A61F2/958
Filed: 1977-08-05
Abstract: A material dispensing apparatus for placing a material in the uterine cavity and moving the material from the uterine cavity into the fallopian tubes of a female. An elongated probe carries an expandable member, and a housing connected to the probe has a piston and cylinder structure and a container for storing the material. Material and expansion drive mechanisms are connected to a single actuator selectively controllable by an operator. When the actuator is operated it is moved into the housing to both dispense the material and expand the expandable member. Pressure control means are provided in the drive linkage for expanding the expandable member to assure that a predetermined maximum pressure is not surpassed. The operator may fully depress the actuator and the pressure control means will both determine the maximum pressure and substantially maintain that pressure should a leak occur. Additional pressure control means are provided in the cylinder structure to compensate for atmospheric pressue change and to coordinate the balloon expansion relative to the material dispensing. Means are also provided in the material dispensing drive linkage to prevent the dispensed material from flowing back into its container when maximum pressure is applied. A replaceable probe portion is provided in the preferred embodiment.

Title: Reflective insulation assembly
IPC: E04B1/74
Filed: 1979-01-31
Abstract: A highly flexible reflective insulation inner assembly is provided which spaces a pair of flexible reflective insulation sheets while also sealing a volume of space therebetween.
