Abstract: Cette invention concerne une méthode de dosage de l'alimentation en produit détergent d'une machine à laver industrielle qui fait appel à la détermination d'une propriété de l'eau de lavage fonction de la concentration de détergent dans l'eau et qui commande l'ajout de détergent lorsque la valeur de la propriété mesurée correspond à une concentration de détergent inférieure à une valeur de consigne, la propriété mesurée étant la conductivité électrique de l'eau de lavage et l'instrument de mesure, une cellule comportant une ou plusieurs électrodes (3, 4). La méthode comporte une étape a) d'ajout à l'eau fraîche de remplissage initial de la machine d'une quantité de détergent propre à réaliser la concentration de consigne, suivi du brassage de l'eau additionnée de détergent; une étape b) de mesurage de la conductivité de la liqueur de lavage après moins de deux minutes de brassage et une étape c) d'entrée de la valeur de conductivité mesurée et de la concentration de détergent correspondante dans la mémoire d'un contrôleur (1) pour servir de valeurs de consigne en fonction desquelles régler l'ajout de détergent au besoin.

Title: Automatic multiple-decanting centrifuge
Inventor: GANN STEVEN M
IPC: B65D41/50
Filed: 1996-04-30
Granted: 2007-02-20
Abstract: A centrifuge is capable of holding a sample container in selected orientations, either during or after centrifugation, to drain supernatants between two or more chambers of the container. The draining may be gravity or centrifugal draining. This allows an automated process to subject a sample to a first physical or chemical treatment to produce a first supernatant, the first supernatant to be subjected to a second physical or chemical treatment, and a second supernatant to be separated from a desired component.

Abstract: Cross-over modulation between radio frequency circuits and audio circuits is minimized in a wireless portable transceiver by locating all audio circuitry in a first section of the portable transceiver and all radio frequency circuitry in a second, separate section of the portable transceiver. In view of modality considerations in small portable transceivers, an audio signal is either radiated or received in the vicinity of the radio frequency circuitry. Isolation of the audio signal is achieved by routing this signal while in its acoustic form. Since audio signals in an electrical form are not routed around or near the radio frequency circuitry, cross-over modulation does not occur between the radio frequency circuitry and the audio circuitry.

Abstract: Mutants of the human PAI-1 protein are described which are inhibitors of neutrophil elastase or are inhibitors of vitronectin (Vn)-dependent cell migration. These mutants preferably comprise one or two amino acid substitutions in the reactive center loop of PAI-1, particularly at positions 331 and 346 of the mature protein. These mutants are notable in being resistant to inactivation by elastase, having high affinity for Vn, or both properties. These mutant proteins as pharmaceutical compositions are used to inhibit elastase in a subject, thereby treating a number of disorders associated with elastase activity, most notably emphysema, ARDS, inflammatory lung injury and cystic fibrosis. The mutants which interact with Vn are used to inhibit cell migration in a subject, thereby treating diseases or conditions associated with undesired cell migration and proliferation, particularly of smooth muscle cells. Such conditions include atherosclerosis, post angioplasty restenosis, fibrosis associated with chronic inflammation or chemotherapy, tumor invasion and metastasis and conditions in which angiogenesis is pathogenic. Also disclosed are peptides of such mutant proteins, mutant-specific antibodies, nucleic acid molecules, particularly DNA, encoding the mutant protein and host cells transformed by such nucleic acids.

Abstract: A flameless combustor eliminates the flamme as a radiant heat source, which results in a more even temperature distribution throughout the length of the burner. Flameless combustion is accomplished by preheating the fuel and the combustion air to a temperature above the autoignition temperature of the mixture. The present invention lowers the autoignition temperature by placing a catalytic surface within the desired combustion chamber. Temperatures are maintained above the catalyzed autoignition temperature but less than the noncatalyzed autoignition temperatures for noncatalyzed reaction. Thus, the amount and location of reaction can be controlled by varying the amount and distribution of catalyst within the burner. Removing heat from the combustion chamber in amounts that correspond to the oxidation of fuel within different segments of the combustion chamber can result in low temperatures and relatively even distribution of heat from the burner.

Abstract: A transvenous bipolar lead (1) specifically designed for coronary sinus implantation. The lead has essentially two main characteristics, the distal end has a 45-degree pre-shape to facilitate introduction of the lead through a catheter and provide optimal positioning of the lead (1) within the coronary sinus. The lead further features a distal electrode tip (20) which itself is canted at an angle of 45 degrees on the distal end of the lead to provide a very close contact with the coronary sin us upper wall and, thus, with the left atrium inferolateral wall. In addition, each of these sections (51, 53) is flexible to permit the lead to be introduced through a relatively small-sized guide-catheter. Finally, the lead further features a center lumen to also permit the lead to be straightened for introduction with a stylet.

Abstract: A detector 50 is included in a laser apparatus for generating a high energy laser beam to protect against the uncontrolled escape of the high energy laser beam from its prescribed optical path 40. The high energy laser beam proceeds along the optical path 40 and is directed to a work site 44 by a series of reflective surfaces in its path 26 and 30. The series of reflective surfaces function to change the path 14 of the beam 32 from the generating source to the work station 44. Associated with each of the reflective surfaces is a detector 50 which comprises a conductive frame 51 having a front face 52 and a back face 54. The back face 54 is equipped with a thermal sensor 60 which is positioned in a base portion 64 of the heat conductive frame 51. The detector is equipped with cooling means 58 and 66 for maintaining the threshold temperature. The sensor 60 which is affixed to the base portion 64 having a controlled thickness is preset at a threshold temperature such that in the event the reflective surfaces 26 or 30 breaks or otherwise fails permitting the beam 34 to strike the heat conductive frame 51 it would cause sudden rise in temperature of the sensor which would trigger the control circuit 69 to shut down the power supply 92 that energizes the high energy gain module 12.
