Patent ES-467569-A1 (ES)
Title: Oxygen-lime distributor for steelmaking vessel
IPC: C21C5/48
Filed: 1978-03-04
Abstract: Excessive wear is eliminated in a distributor utilized in a bottom-blown oxygen steelmaking converter for distributing oxygen and entrained lime to the converter tuyeres by the provision of a spiral ramp that extends between the inlet and outlet regions of the affected portion of the distributor. The ramp is arranged to mechanically separate the entering oxygen-lime mixture from that flowing through the affected region thereby preventing the interference between the two flows and the wear-producing flow acceleration attendant therewith.

Patent ES-482319-A1 (ES)
Title: Tandem master cylinder
IPC: B60T8/26
Filed: 1979-07-09
Abstract: In a known tandem master cylinder with a regulator, machining and assembly of the parts is complicated which renders the master cylinder costly. Moreover, such an arrangement is only realizable with master cylinders having a large diameter. There are also functional disadvantages, particularly in the event of failure of one brake circuit, the brake fluid volume consumption of the other brake circuit is materially increased which results in an additional increase of the pedal travel. To avoid these shortcomings, the present invention provides a tandem master cylinder with a regulator including an arrangement, which in the event of failure of the front-axle brake circuit, mechanically actuates the regulator valve coupled to the rear-axle brake circuit by a pressure piston to keep the regulator valve in the open position to enable unreduced braking pressure to be coupled to the rear-axle brake circuit.

Patent ES-8106393-A1 (ES)
Title: Combined thermostatic control and thermal fuse overtemperature protector for electrical heating appliances
IPC: H05B1/02
Filed: 1980-11-28
Abstract: An overtemperature protector for an appliance having an electrical heating element, the overtemperature protector being formed basically of just a spring blade positionable to bring a contact on the surface of the blade into circuit-energizing engagement with a fixed contact, and an insulator-capped fusible pin retaining the blade in that position. Excessive heat in the appliance softens the pin, allowing the spring blade force on the insulator cap to shear the pin and interrupt the circuit. The overtemperature protector is preferably incorporated in a thermostatic control, the fixed contact being supported on a lateral extension projecting from one circuit element of the thermostat assembly and the spring blade being supported within the assembly with an insulating spacer separating it from the thermostat element having the lateral extension. The spring blade is preferably sickle-shaped for compactness despite having a long length for low force to minimize effects of creep of the fusible pin. The spring blade engages the fusible pin at a point well beyond the contact, the result being that a much smaller force is exerted on the pin for any desired force between the contacts.
Patent ES-8201090-A1 (ES)
Title: Container and closure having frangible opening means
IPC: B29C65/08
Filed: 1980-12-17
Abstract: A container (4) has a closure (15) which consists of a fastener (6) and a lid (1) which are joined together all the way round by a failure zone (2). When the container is originally sealed the closure is inserted into the opening and the fastener is fixed to a flanged top surface (5) which surrounds the opening. The failure zone is located at the point at which the internal surface (3) of the opening meets the top surface of the opening. The lid is dished inwards within the failure zone in such a way that the outer edge of the dishing (7) forms a guide (10) against the internal surface (3). A surface (8) of the lid running parallel with the top surface is connected to the guide (10). The lid is broken open and is torn along the length of the failure zone by a locally applied force. The application of force inwards will as a rule move the lid over the distance a until the surface (8) makes contact with a ledge (11) located inside the container (4). The surface (8) supporting the material of the lid thus forces the guide (10) against the wall of the container and holds the lid in a sealing position inside the opening. The lid adopts a similar position in a re-sealed container. Gripping devices, preferably in the form of stiffening ribs, make it easier to remove the lid from the position just mentioned.
