Title: Coupling assembly for corrugated decks
Inventor: CORNWALL KENNETH R
IPC: E03F5/04
Filed: 1993-02-26
Granted: 1996-04-02
Abstract: An improved coupling assembly (10) mounted on a  corrugated  deck  (30)  and  embedded  in  a  concrete partition, such as floor (100), to provide an opening through the deck and the floor,  is described.   The coupling is comprised of an inner conduit (13) mounted inside of an outer sleeve (11).  A flange portion (15) is provided at one end of the  sleeve and  includes openings  (19)  for fastening means,  such as nails or screws (21) that serve to secure the coupling assembly in position on the deck.  The conduit is mounted to the inside (11A) of the sleeve to position the opposed open ends (13B) and (13C) of the conduit extending beyond the sleeve means and through an opening (50) in the deck. The sleeve enables the contact point between the sleeve and the conduit to be adjusted along the length of the conduit.  This is useful in those situations where the conduit  has  been  mounted  in  an  existing  building construction or where the mounting position between the conduit and sleeve needs to be adjusted.  The coupling is then embedded in the poured concrete floor and fluid carrying pipes can be connected to the opposed open ends of the conduit.  The partition need not necessarily be a floor, but instead can comprise a wall.  The floor can also be sloped and an upper end of the conduit can be provided with a drain conduit (61) for removing liquid from the top of the sloped floor.

Abstract: A method for aiding in the diagnosis of, and monitoring the progression or course of, lung cancer in a patient by measuring the amount of NCA 50/90 in a blood sample, e.g., serum sample, obtained from the patient. Measurement in a single sample of an amount of NCA 50/90 significantly higher than the mean amount of NCA 50/90 in the normal population is an indication of lung cancer in a symptomatic patient. The course of lung cancer can also be monitored by performing a series of specific immunoassays over time to determine changes in the level of NCA 50/90 in blood samples.      Increases in blood NCA 50/90 levels over time are indicative of a deteriorating condition whereas decreasing levels of blood NCA 50/90 over time indicate an improving condition.

Abstract: L'invention se rapporte à un outil de forage (20) servant à amener un fluide (par ex. du sable ou de la boue graveleuse) à différents niveaux à l'intérieur d'un puits de forage, qui se compose d'un conduit d'amenée (21) pourvu lui aussi d'une pluralité d'orifices de sortie (29) espacés sur sa longueur. Un tube de sortie (27) est raccordé à chaque orifice de sortie. Chaque tube de sortie (27) comprend une partie dont la longueur est sensiblement parallèle à l'axe longitudinal du conduit d'amenée (21), et l'utilisation de ces tubes permet d'élargir les orifices de sortie, et grâce au conduit d'amenée, les probabilités qu'aurait un orifice de sortie (29) d'être bouché par le sable avant l'achèvement d'une opération de forage, sont sensiblement réduites. De plus, lorsqu'au moins une partie d'un tube de sortie se trouve à l'intérieur du conduit d'amenée (29), la concentration de sable s'écoulant dans le tube de sortie (27) sera sensiblement identique à la concentration d'origine dans la boue puisque les particules de sable n'auront pas tendance à dévier d'un orifice de sortie (29) et resteront dans la boue. Ceci empêche la déshydratation prématurée de la boue et l'acccumulation du sable à l'intérieur du conduit d'amenée (21) normalement associée à ce phénomène.
