Patent ES-451546-A1 (ES)
Title: Method for explosive breaking of hard compact material
IPC: F42D3/04
Filed: 1976-09-15
Abstract: A hard compact material, such as rock, is broken by delivering an explosive into at least one hole which has been pre-drilled in the material to be broken and by forcing a relatively incompressible fluid, such as water, into the hole to impact the explosive to initiate same. Upon detonation of the explosive the fluid stems the hole thereby delaying leakage of blasting gases out of the hole before the material is broken. Preferably, the explosive and the fluid are launched together into the hole. In this case may the explosive and the fluid be encapsulated in a common cover.

Title: Automatic tank emptying mechanism - has discharge valve operated by actuator with blance arm and float slidable along vertical guides
IPC: F16K31/26
Filed: 1976-12-07
Abstract: This mechanism is designed to discharge liquid from a tank when a predetermined level is reached and to close the discharge port when the tank is virtually empty. The mechanism which actuates the discharge valve is not contaminated by the liquid. The tank (1) is divided into a deep section (2) and a shallow section (3), the first containing the liquid (5) and the second the actuator mechanism. A signal to operate the actuator is provided by a float (10). Both float and actuator can slide up and down vertical guides (11, 99). The actuator consists of a balance arm supported on a pivot (16) and having a container (80) at one end housing a mobile mass (12). This transfer causes the arm (15) to swing quickly up or down as the horizontal is reached under the action of the float and the motion then causes rapid opening or closing of the valve (6).

Patent ES-464877-A1 (ES)
Title: Axially alignable nuclear fuel pellets
IPC: G21C3/28
Filed: 1977-12-07
Abstract: The invention is directed to an axially alignable nuclear fuel pellet of the type stacked in end-to-end relationship within a tubular cladding. Experience has shown that fuel cladding failures can occur at pellet interface locations due to mechanical interaction between misaligned fuel pellets and the cladding. Mechanical interaction between the cladding and the fuel pellets loads the cladding and causes increased cladding stresses. Nuclear fuel pellets constructed according to the invention are provided with an end structure that increases plastic deformation of the pellets at the interface between pellets so that lower alignment forces are required to straighten axially misaligned pellets. Plastic deformation of the pellet ends results in less interaction between the cladding and the fuel pellets and significantly lowers cladding stresses. The geometry of pellets constructed according to the invention also reduces alignment forces required to straighten fuel pellets that are tilted within the cladding. Plastic deformation of the pellets at the pellet interfaces in both axial and transverse directions is increased by providing pellets with at least one end face having a centrally-disposed raised area of generally convex shape so that the mean temperature and shear stress of the contact area is much higher than that of prior art pellets. Fuel pellets constructed according to the invention may be provided with one end having a centrally-disposed raised area and the opposite end flat or the opposite end may also be provided with a centrally-disposed raised area, or the opposite end may be provided wth a centrally-disposed depression having a depth less than the height of the raised area of an adjacent pellet.

The one-way throttling valve may be arranged in one of the two vacuum line connectors of the valve housing of a thermostat relief valve.
Patent ES-8102306-A1 (ES)
Title: Seal and seal assembly.
IPC: F16J15/32
Filed: 1979-12-26
Abstract: A seal (16) has a body (38), a leg (40) and first and second sealing areas (42, 44). The seal (16) is used in a seal assembly (10) having first and second members (12, 14) such as, for example, a frame portion (20) and steering knuckle (27) of a work vehicle. Apparatus (28) such as a bearing (30) supports the knuckle (27) in rotation relative to a king pin (24) of the frame portion (20). The foreign matter can enter between the frame portion (20) and steering knuckle (27) and interfere with vehicle steering. In the assembly (10), the sealing surfaces (42, 44) contact substantially perpendicular surfaces (32, 34) of the frame portion (20) to block passage of foreign matter to the bearing (30). A second end portion (54) of the seal leg (40) can be controllably deflectable in order to permit overfill of lubricant to pass from the bearing cavity between the frame portion (20) and steering knuckle (27).

Patent ES-8305871-A1 (ES)
Title: Rain water roof outlet or similar for a building
IPC: E04D13/04
Filed: 1982-05-26
Abstract: A rain water roof outlet for a building for conducting rain water from a roof as an airless flow, i.e. as a full water flow. The arrangement includes a vertical pipe which at its upper end is connected to a wider trough mounted at the level of the roof. In the trough, above the mouth of the vertical pipe, is mounted a lid, which by special formation of its shape or by means of additional elements is adapted to increase the friction against the water flowing towards the mouth of the vertical pipe. This friction counteracts the tendency of creating whirls in the water stream and thereby contributes to producing full water flow in the vertical pipe by preventing air entry. The lid is preferably a net.
