Filed: 1997-03-20
Abstract: A method of treating infertility disorders by 1) administering an LH-RH antagonist, preferably Cetrorelix, in amounts to selectively suppress endogenous LH but not FSH secretion and 2) inducing follicle growth by administration of exogenous gonadotropin. The selective suppression OF LH allows FSH secretion to be at natural level S thereby not affecting individual estrogen development. The LH-RH antagonist can be given as a single or dual subcutaneous dose in the range of 1 mg to 10 mg, preferably 2 mg - 6 mg. In multiple dosing posology, LH-RH antagonist can be administered subcutaneously in an amount in the range of 0.1 to 0.5 mg of LH-RH antagonist/day.  LH-RH antagonist is applied starting cycle day 1 to 10, preferably on day 4 to 8, and ovulation can be induced between day 9 and 20 of the menstruation cycle by administering rec. LH, native LH-RH, LH-RH agonist or by HCG. In addition rec. LH, native LH-RH or LH-RH agonist can be given to avoid hyperstimulation syndrome and native LH-RH or a LH-RH agonist can be administered to avoid luteal phase stimulation by neutralizing the negative effects of HCG.

Title: Process for manufacturing electrical circuit bases
Inventor: MEYER HEINRICH
IPC: H05K3/06
Filed: 1995-10-18
Abstract: To manufacture electrical circuit bases with extremely fine conducting paths, laminates without metal foil coverings are used as the initial materials; to produce the holes, a temporary metal layer is applied to the laminate surfaces, that metal layer is structured and etched and removed from the laminate surfaces once the holes have been etched in the laminate. A  foundation metal layer is then deposited on the laminate surfaces, including the hole walls, to create the conducting paths; this is done by the glow discharge decomposition of volatile metal compounds. Further metal layers are applied to those layers without current and/or electrolytically. The metal layers are structured using photomask techniques.

Abstract: A reciprocal skimmer has a ramp assembly and a skimming blade assembly.  The ramp assembly has a sheave with a lifting wheel and a guide wheel and is journaled on a carriage.  The carriage is interconnected with a skimming blade by a slot and pin arrangement.  A lifting cable is coiled on the lifting wheel and is attached to the skimming blade.   A guide cable is coiled on the guide wheel and attached to a hold down positioned above the carriage.  A ramp  on  a  dissolved  air  floatation basin  is  used  to separate surface sludge from the basin and remove it to a hopper.  The ramp has a slope equivalent to its angle of inclination with horizontal, and the ratio of the radii on the lifting wheel and the guide wheel is equal to the slope of the ramp.   This assures that the skimming blade is evenly raised and advanced over the ramp.  A skimming blade assembly has a lifting cable and two pulleys, for lifting and lowering a  skimming blade on a carriage which  is otherwise similar to the ramp blade assembly. The skimming blade also utilizes a pin and slot arrangement with a saddle positioned at the top of the slot.   The lifting cable pulls the pin out of the saddle prior to beginning a skimming run.  The reciprocal skimmer is driven by a ball screw apparatus.

Patent CA-2226506-A1 (CA)
Title: Thermometre clinique electronique
Inventor: NAIL WILLIAM L
IPC: G01K7/42
Filed: 1996-07-11
Abstract: L'invention a pour objet un thermomètre qui permet de prévoir dans des délais brefs la température du corps sur la base de signaux de température émis par une sonde de température lorsque celle-ci est mise en contact avec le corps. On établit les logarithmes représentant les différences entre les signaux de température sur une tranche de temps donnée. On construit une courbe des logarithmes dont la pente sert de constante de temps du système en vue de la prévision de la température finale du corps. Cette constante de temps sert, conjointement avec d'autres constantes prédéterminées, à calculer la température prévue. La qualité des données fournies dans la tranche de temps considérée est contrôlée. Si elle s'avère ne pas être d'un niveau acceptable, une tranche de temps différente de signaux de température est choisie aux fins de prévision. Le processeur commute sur un mode de contrôle si la qualité des données mesurées sur un nombre limité de tranches de temps est inacceptable. Pour déterminer l'instant de début sur lequel est basée la tranche de temps des mesures de prévision, on effectue la somme des dérivées secondes des signaux de température relevés par tranche de temps. L'instant de début est déterminé lorsque la somme des dérivées secondes d'une tranche de temps donnée dépasse un certain seuil.
