Abstract: Procédé de fonctionnement d'un moteur à combustion interne permettant de limiter le plus possible les émissions de NO¿x? dans les gaz d'échappement et consistant à détecter la charge appliquée sur le moteur du véhicule, et à déterminer si elle est faible ou élevée. Quand une charge faible est détectée, l'air non étranglé et une certaine quantité de carburant permettant une combustion pauvre, sont mélangés à l'injection (4) de carburant, à proximité du point mort supérieur pendant la course de compression. Quand une charge élevée est détectée, l'air étranglé et une certaine quantité de carburant commandée par la teneur en oxygène détectée des gaz d'échappement, sont mélangés selon un rapport approximativement stoechiométrique avec l'injection (4) de carburant beaucoup plus tôt que pour l'injection à charge faible, de préférence, pendant la course d'admission.

Abstract: Apparatus and method for detecting surface defects on an article freely standing on a conveyer, which generate profile trace data corresponding to profile trace at a cross section of the article. A surface shape inspection unit comprising an optical ranging system using laser and camera is provided for obtaining the profile trace data through triangulation-based derivation techniques. Base reference curves are derived from regular portions of the profile trace data. Profile trace data are compared to defect threshold curves to recognize a defect induced departure of the trace data with respect to the base reference curve and to produce a defect output signal. The apparatus and method according to the invention are particulary useful for detecting roughness, cavities, wane, missing wood and altered wood on lumber pieces which are conveyed at high speed.

Abstract: The present invention is directed to a new and useful method and apparatus for use in determining, the levels of macular pigments in the tissue of live subjects.  Specifically, the method and apparatus of the present invention provide a. non-invasive, rapid, and objective determination of the macular carotenoid levels, and in lurn, offer valuable diagnostic intormation applicable to large populations. The present invention measures the levels of macular carotenoid pigments, as well as other retinal materials.  Monochromatic laser light is projected onto a retina, preferably in the macular area. A  very sensitive detection system then detects light scattered from the retina.  The majority of the light is scattered elastically at the same wavelength of the laser in a manner known as Rayleigh scattering. A very small fraction of laser light is scattered inelastically at a wavelength different from that of the laser in a manner known as Raman scattering. The Raman scattered light is selected and then routed to a detection system, wherein the results are calibrated against actual standards for the particular retinal material being tested

Abstract: A one trip whipstock system includes both a one trip combination mill and associated whipstock. The one trip combination mill comprises an upper cutter and lower cutter below the upper cutter. The upper cutter and lower cutter are joined by a cone that widens towards the upper cutter. In operation, a whipstock is connected to the drilling sub by shear bolts. A guide lug on the whipstock faces the drilling sub between the lower cutter and upper cutter for riding on the cone when the drilling sub is advanced along the whipstock. Preferably the shear bolts connect to the lower cutter. Also, the, lower cutter has smaller gauge than the upper cutter, to such an extent that the relative gauge sizes of the lower cutter and upper cutter permit the upper cutter to exit casing during drilling before the lower cutter exits casing. Further, there may be provided a watermelon mill and a string mill above the upper cutter and the watermelon mill, string mill and the upper cutter preferably have the same gauge. To reduce outer diameter wear on the upper cutter, it has a square leading edge.

The present invention also relates to methods of altering serum lipids in subjects to treat, for example, hyperlipidemia in hyperlipidemics, lipidemia in normolipidemics diagnosed with or predisposed to cardiovascular disease, and atherosclerosis, by administering such oral solid pharmaceutical combinations once per day as a single dose during the evening hours, without causing drug-induced hepatotoxicity myopathy or rhabdomyolysis, or without causing in at least an appreciable number of individuals drug-induced hepatotoxicity, myopathy or rhabdomyolysis to such a level that discontinuation of such therapy would be required. More particularly, the present invention concerns oral solid pharmaceutical combinations comprised of, for example, (1) an HMG-CoA reductase inhibitor for immediate or extended release, (2) nicotinic acid, a nicotinic acid compound or mixtures thereof, and (3) a swelling agent to form a sustained release composition for extended release of the nicotinic acid or nicotinic acid compound or mixtures thereof for nocturnal or evening dosing for reducing serum lipids and increasing HDL-cholesterol. In accordance with the present invention, and by way of example, a composition for oral administration during the evening hours to alter serum lipids comprised of nicotinic acid and hydroxypropyl methylcellulose in the form of an extended or sustained release tablet or caplet coated with a coating comprising an HMG-CoA reductase inhibitor in immediate release form is disclosed. Also in accordance with the present invention, the pharmaceutical combinations may include a nonsteroidal and-inflammatory agent for reducing the capacity of nicotinic acid or nicotinic acid compounds to provoke flushing reactions in individuals.

Abstract: A spanning or beam member for use in construction having a pair of opposing C-shaped flanges and a corrugated web. Laterally extended protrusions of the web strengthens the beam member by stiffening the web and increasing the load bearing forces that may be carried by the beam member without crushing. The C-shape of the flanges allows welding of the flanges to the protrusions of the web to reduce the unbraced and unstiffened size of the compression elements to allow for construction of beam members of a given strength out of thinner sheet material. An end plate secures to the opposing flanges and to the corrugated web interposed therebetween, providing a superior means for interconnecting the beam members.

Abstract: This invention is of a resin composition including an additive of one or more organic peroxide thermal imitators to cationic photoinitiators, that are sensitized with alpha-hydroxy-ketones, which composition provides a self-- propagating thermal curing reaction first activated by a short duration of surface ultraviolet radiation. The thermal reaction is non-directional, thus eliminating the line of sight limitation of current radiation curing processes. Complete curing can be achieved of the composition in a very short time; often after only a few minutes or less. The activation period can be provided by only a few seconds of ultraviolet light using a wide variety of commercial ultraviolet light sources.
