Title: Producto ignífugo.
Inventor: MARTINEZ DE LA TORRE CARLOS
IPC: C09K21/14
Filed: 2011-11-22
Granted: 2014-04-24
Abstract: Existen pinturas ignífugas que, con diferentes composiciones o formulaciones, ofrecen unos resultados que cumplen escasamente con las exigencias de la normativa legal existente al respecto. El producto ignífugo de la invención supone un avance tecnológico espectacular por cuanto que sus propiedades ignífugas sobrepasan en mucho los límites establecidos por la citada legislación. Para ello el producto ignífugo en cuestión consiste en una mezcla de polifosfato de amonio micronizado, resina polímero estirenado en base acuosa, fibra mineral (lana de roca) y melaminas, en proporciones variables en función de las características de la superficie a la que se va a aplicar el producto o de las características del producto en masa del que ha de formar parte. Complementariamente y también en función de su aplicación, la formulación básica citada puede acompañarse de una serie de aditivos, concretamente hidróxido de magnesio, hidróxido de aluminio, dipentas, micas, trióxido de antimonio y/o serrín de madera o corcho.

Title: Cojinete de levitación fluídica.
Inventor: FERREIRO GARCIA RAMÓN
IPC: F16C32/06
Filed: 2012-04-20

Abstract: El cojinete de levitación fluídica por repulsión inversa objeto de la invención sustenta radial y/o axialmente rotores mediante levitación fluídica conseguida por repulsión inversa hidrostática, o tracción mecánica hidrostática. El estator está dotado en las zonas de sustentación radial y axial del rotor de huecos o cámaras rellenadas con un fluido a presión (normalmente aceite) que es inyectado a través de orificios restrictores de fluido que capacita al rotor para sustentarse en una posición auto-levitante y evitar el contacto entre el estátor y el rotor, de modo que al separarse el rotor del estátor aumenta la fuga de fluido contribuyendo a la disminución de presión del fluido y a la aproximación del rotor al estátor, con lo que se estabiliza en una posición auto-levitante de equilibrio.

Title: Threaded tappet adjuster
Inventor: PETER J GILL
IPC: F01L1/14
Filed: 1980-03-27
Granted: 1984-12-06
Abstract: The valve operating mechanism(10) includes an automatic clearance adjuster (14) between two components, one component(22) being a push rod and the other(12) a nut. The components (12,14) have cooperating screw threads(16,32) and are spring-loaded into engagement when no valve-operating force is being transmitted. A predetermined axial free play is provided in the threads to determine the clearance in the valve operating mechanism. A high friction is provided in one direction of axial loading of the screw threads compared to the friction in the opposite direction to prevent relative rotation between the components(12,14) during valve actuation. Thus, excess clearance is taken up by relative linear movement of the components.

Title: Central air conditioning system
Inventor: TULOWIECKI DAVID A
IPC: F24F11/76
Filed: 1981-07-01
Granted: 1984-11-09
Abstract: The damper arrangement employed to control of flow of conditioned air from a plenum further includes aligned cutoff plates which are provided with a curved surface for coacting with inflatable bellows. By varying the inflation of the bellows, the area between each of the bellows and the cutoff plates may be varied to regulate the quantity of conditioned air discharged into the area or space being conditioned. A normally open solenoid valve is located in line and when the valve is open the unit operates under the control of thermostat. When the valve is closed, the thermostat is no longer able to bleed air and control the inflation of bellows which then inflate fully to close off air flow from the plenum into the zone. As a result, the air conditioning system is positively disabled. Because a solenoid can produce an undesirable hum, a diode bridge is located in the solenoid circuit.
