Title: Sistema y metodo para asegurar y controlar el flujo turbulento para limpiar ductos.
Inventor: PLUMMER RAYMOND G
IPC: B05B15/02
Filed: 1993-06-07
Abstract: Esta invención se refiere a un sistema para asegurar y controlar con exactitud el flujo turbulento de una mezcla comprimida o presurizada de un gas y de un fluido de limpieza, par purgar y limpiar conductos. Las presiones del fluido de limpieza del gas son detectadas continuamente y se transducen en señales eléctricas para controlar válvulas para el gas comprimido, para mantener y asegurar su presión en una cantidad predeterminada con relación a la presión del fluido de limpieza, de modo que cuando el gas y el fluido son mezclado en un aparato para producir una corriente turbulenta, se asegure el flujo turbulento. Las mejoras de este circuito incluyen un transductor-detector de presión, para detectar la presión de la entrada del aire en el dispositivo o aparato para producir una corriente turbulenta, y alimentarlo de regreso al transductor de presión del aire, principal, para mantener en forma exacta una proporción predeterminada entre las presiones del gas y del fluido de limpieza, dentro de menos de aproximadamente 0.07 kg/cm2 (1 psi) en presiones de al menos 10.55 kg/cm2 (150 psi). Una señal de aviso o advertencia de la presión, indica cuando la presión del fluido de limpieza y/o del gas, es demasiado baja para producir un flujo turbulento efectivo. Además, puesto que los circuitos van a ser sensibles, se conecta un filtro pasabajos a al salida del transductor del fluido de limpieza, para evitar la operación innecesaria de las válvulas que controlan la presión del gas  en el aparato que produce una corriente turbulenta, cuando el circuito está en su estado en espera de funcionamiento, por medio de lo cual. se incrementa la duración de estas válvulas para el control del gas. Un circuito de enriquecimiento para los detectores de la presión de fluido de limpieza, puede hacer variar las diferencias en la presión entre el fluido de limpieza, sino también durante la acción de turbulencia. Además, el control exacto de las presiones relativas del gas y del fluido de limpieza, en el aparato que produce una corriente turbulenta, hace posible que la mezcla que fluye en forma turbulenta no solamente limpie los conductos, sino que también los purgue.

Title: Ruber/metal combustion seal.
Inventor: TENSOR PAUL M
IPC: F16J15/12
Filed: 1997-09-25
Abstract: A combustion seal for a cylinder head gasket of an internal combustion engine includes a corrugated rigid carrier having a radially extending base portion, the radially innermost peripheral edge defining a portion of a cylinder bore opening, and three channels defined radially inwardly of the base portion and radially outwardly of the inner peripheral edge. The radially innermost and outermost channels open in a first axial direction while the channel disposed between them opens in the opposite axial direction. An elastomeric ring is received in all but the radially outermost channel, first face of the rings in facial contact with a root of the channel and an opposing second face defined outwardly of the channels when the seal is in a relaxed state. When the gasket is installed, the elastomeric rings elastically compress to become generally flush with the walls of the channel in which they are received.

Abstract: Bij een werkwijze voor het vervaardigen van een paar brillenglazen voor het verbeteren van de visuele prestaties bij patiënten met keratoconus die gecorrigeerd zijn met harde, respectievelijk zachte contactlenzen, wordt gebruik gemaakt van een set pasglazen waarvan een zich aan de onderzijde van het pasglas bevindend segment een positieve respectievelijk negatieve sterkte heeft. Eerst wordt bepaald welk oog van de patiënt de geringste graad van keratoconus heeft. Vervolgens wordt volgens de normale regels van de subjectieve refractie eerst het beste sferische glas bepaald en daarna, uit de set van pasglazen bepaald door verschillende pasglazen van de genoemde set pasglazen volgens de methode voor te houden terwijl de patiënt met beide ogen naar optotypen kijkt. Daarna wordt dit herhaald voor het andere oog van de patiënt. Tijdens de refractie kan het andere oog geneveld worden. Daarna wordt voor elk oog een brillenglas vervaardigd met een sterkte gelijk aan die van het gevonden pasglas, en die een segment heeft met een sterkte gelijk aan de som van de sterkte van het segment van het geselecteerde pasglas en van de sterkte van het sferische pasglas.

Abstract: The material is compressed or comminuted or is used as sludge. Ferrous metal is removed. It is fermented at room temp. It is inoculated with fungus, yeast or mould chosen from the classes Blastomycetes, Basidiomycetes or Deuteromycetes. Fungi imperfecti types are used which have a strong tendancy to form colonies and to compete with other organisms.
